The Arctic is Melting – So What?

A view of sea ice in the Artic Ocean.

The activities are as follows:

Think of the North Pole as one big ice cube – a vast sheet of ice, only a few meters thick, floating over the Arctic Ocean. Historically, the amount of Arctic sea ice would be at a maximum in March. The cold temperatures over the long winter cause the ocean water to freeze and ice to accumulate. By September, the warm summer temperatures cause about 60% of the sea ice to melt every year. With global warming, more sea ice is melting than ever before. If more ice melts in the summer than is formed in the winter, the Arctic Ocean will become ice-free, and would change the Earth as we know it.

This loss of sea ice can have huge impacts on Arctic species and can also affect climate around the globe. For example, polar bears stand on the sea ice when they hunt. Without this platform they can’t catch their prey, leading to increased starvation. Beyond the Arctic, loss of sea ice can increase global climate change through the albedo effect (or the amount of incoming solar radiation that is reflected by a surface). Because ice is so white, it has high albedo and reflects a lot of the sunlight that hits it and keeps the earth cooler. Ice’s high albedo is why it seems so bright when the sun reflects off snow. When the ice melts and is replaced by water, which has a much lower albedo, more sunlight is absorbed by the earth’s surface and temperatures go up.

Scientists wanted to know whether the loss of sea ice and decreased albedo could affect extreme weather in the northern hemisphere. Extreme weather events are short-term atmospheric conditions that have been historically uncommon, like a very cold winter or a summer with a lot of rain. Extreme weather has important impacts on humans and nature. For example, for humans, extreme cold requires greater energy use to heat our homes and clear our roads, often increasing the use of fossil fuels. For wildlife, extreme cold could require changes in behavior, like finding more food, building better shelter, or a moving to a warmer location.

To make predictions about how the climate might change in the coming decades to centuries, scientists use climate models. Models are representations, often simplifications, of a structure or system used to make predictions. Climate models are incredibly complex. For example, climate models must describe, through mathematical equations, how water that evaporates in one region is transferred through the atmosphere to another region, potentially hundreds of miles away, and falls to the ground as precipitation.

James is a climate scientist who, along with his colleagues, wondered how the loss of arctic sea ice would affect climates around the globe. He used two well-established climate models – (1) the UK’s Hadley Centre model and (2) the US’s National Center for Atmospheric Research model. These models have been used previously by the Intergovernmental Panel on Climate Change (IPCC) to predict how much sea ice to expect in 2100.

How the cricket lost its song, Part II

In Part I you determined that the Kauai flatwing mutation led to a decrease in parasitism rates for male crickets. Today, most of the male crickets on Kauai have evolved flat wings and can no longer produce songs that were previously used to attract female crickets. Without their songs, how do males attract females?

Robin collecting data on satellite behavior in normal and flatwing mutation males.

The activities are as follows:

Without their song, how are flatwing crickets able to attract females? In some other animal species, like birds, males use an alternative to singing, called satellite behavior. Satellite males hang out near a singing male and attempt to mate with females who have been attracted by the song. This helps satellite males in two ways: they don’t use energy to make a song, and they avoid attracting enemies like the fly. Perhaps the satellite behavior gives flatwing males the opportunity to mate with females who were attracted to the few singing males left on Kauai.

Collecting crickets at the speaker.

To test this idea, Robin set up a speaker playing cricket songs in the fields where the crickets live on Kauai, Oahu, and the Island of Hawaii. The speaker tricks male and female crickets into thinking there is a male cricket in the area making songs. Before the start of the experiment, Robin removed all the males found within a 2-meter circle around the speaker. She then broadcast cricket songs from the speaker for 20 minutes. She returned and counted the number of males in the 2-meter circle, measured the distance from male to the speaker, and noted whether each male was normal or flatwing. Robin expected that flatwing males would be more likely to use satellite behavior and, therefore, would be on average closer to the speaker than normal males.

Carina Baskett	Michigan State University	I became interested in biology when I was in high school, so I joined Science Olympiad. I went to college at Rice University in Houston, Texas, my hometown. I did some research on pollination in college, and decided that I really enjoyed learning about the relationships between plants and insects. Before starting my PhD, I did a year-long Watson Fellowship, an independent study abroad. I traveled to different ecosystems in Ecuador, Chile, Panama, and Spain, and made a podcast about relationships between people and nature. For my PhD, I studied pollination and herbivory and how they change with latitude—lots of travel again!	Where to find the hungry, hungry herbivores & Are plants more toxic in the tropics?
Heather Bateman	Arizona State University	I am a field ecologist and conservation biologist interested in how human land-use affects vertebrate populations and habitats. As Earth’s ecosystems move into a future of growing human influence, restoring the integrity of these ecosystems will become central to the conservation of biodiversity. Human activities tend to perturb ecosystems by suppressing natural disturbances such as flooding or fire. This can lead to a decline in native species and proliferation of non-native species. My research interests lie in exploring population responses to habitat alteration, with a particular interest in amphibians, reptiles, and birds.	Lizards, iguanas, and snakes! Oh my!
Karen Beard	Utah State University	My research focuses on how changing landscapes influence species interactions and ecosystem functioning. My research is often done in the context of non-native species and/or climate change.

Mangroves on the move
Sarah Davies	University of Texas at Austin & Boston University	Changing climates and ongoing anthropogenic habitat modifications threaten natural ecosystems worldwide. Research in my lab studies the potential roles of acclimation, adaptation, and dispersal in an organism’s response to rapid climate change. Understanding how symbioses are maintained is fundamental as climate change disrupts symbiotic relationships worldwide. The coral–Symbiodinium symbiosis is essential and serves as the cornerstone for the entire reef ecosystem.	Won’t you be my urchin?
Erin de Leon Sanchez	University of California - Santa Barbara	I am a Ph.D. student in Ecology, Evolution, and Marine Biology at the University of California, Santa Barbara studying the effects of marine heatwaves on the ecologically and commercially important red sea urchin, Mesocentrotus franciscanus. Prior to graduate school, I earned my B.S. in Biology at the University of California, Davis and researched how warming and hypoxia affect Chinook salmon. Overall, I am interested in how commercially important aquatic species may adapt to climate change and its associated stressors.	Do urchins flip out in hot water?
Clara Deser	National Center for Atmospheric Research	I study global climate variability and climate change using observations and models, with an emphasis on interactions among the atmosphere, ocean, and sea ice. My recent projects include the role of internal variability in regional climate change, the effects of projected Arctic sea ice loss on global climate, asymmetries between El Nino and La Nina, and Pacific decadal variability.	The Arctic is Melting – So What?
Leila Desotelle	Michigan State University	My research explores how food web subsidies can influence communities. I study the Kalamazoo River, which has several dams. Dams change the flow of the water and can increase the production of phytoplankton. The phytoplankton can act as a subsidy both temporally and spatially. Stream insect communities change along the river, and some of this response is to the subsidy from dams. Rivers frequently have multiple dams though many are aging and will be removed in the coming decades. Therefore, understanding how dams change food sources is important for the management of rivers.	Float down the Kalamazoo River
Colin Donihue	Harvard University & Washington University	I am an evolutionary ecologist studying the drivers and consequences in intra-specific variation in animal functional traits. In particular, my research focuses on predicting changes in behavioral, morphological, and performance traits as a result of changes in ecological context.

Carleigh Engstrom	Biotechnology High School & Monmouth University	I teach Molecular and Agricultural Biotechnology to tenth graders in New Jersey. I hope to instill my love for biology with all of my students, and one way I do that is by staying current. During the summer of 2018, I participated in a Research Experience for Teachers (RET) program at Monmouth University's Phifer-Rixey lab. This research experience allowed me to get involved with a striped bass project, where we determined the stock populations for striped bass that were sampled off the NJ coast. I truly enjoy sharing this experience with my students, as a way to show them all that science has to offer.	Fishy origins
Meredith Everett	University of Washington & NOAA	My research explores how organisms interact with and adapt to their environments on a genomic scale, and how knowledge of these interactions can be applied to conservation and management solutions. During my time in the Seeb Lab I worked on SNP discovery, developing novel genomic maps for Pacific salmonids, and using these maps to discover the genomic regions associated with ecological traits through QTL and association mapping. I was also involved in a project using SNPs to track sockeye salmon in Bristol Bay, Alaska. I currently work at NOAA on the phylogenetics of deep-water corals.	Salmon in hot water
Ilka (Candy) Feller	Smithsonian Environmental Research Center	I am a mangrove ecologist.

Michael Finiguerra	University of Connecticut-Avery Point	My PhD dissertation investigated the evolution of tolerance to toxins. Today I am a professor at the University of Connecticut, Teaching is my passion. I love interacting with students and coaching them through complex problems. To me, science is more than intellectual content. It is a lens through which to teach critical thinking. Helping my students become independent critical thinkers is my goal. I use my research as a tool for teaching; it connects the real-world to classroom lectures and gives student much needed hands-on experience, in both laboratory and field-settings.	Dangerous aquatic prey: can predators adapt to toxic algae?
Susan Finkbeiner	University of California, Irvine & Boston University	I spent my childhood chasing butterflies and collecting insects in Illinois, with the dream of studying butterflies in the tropical rainforest. As an undergrad at Cornell I did a semester abroad in Costa Rica where I was introduced to Heliconius butterflies. For my PhD I worked with these butterflies to examine how natural and sexual selection drive the evolution of butterfly wing patterns. I am currently a postdoctoral researcher at Boston University (Mullen Lab) working with Adelpha butterflies to understand the ecological and evolutionary processes that shape patterns of biodiversity.	Why are butterfly wings colorful?
Erika Foster	Colorado State University	I strive to answer complex questions about soil productivity and to inspire the next generation of soil ecologists. I aim to work with diverse communities from farmers to students, to discover best land management practices, and to ignite curiosity and passion for science.

Specifically, I study how land-use and climate changes in montane forest landscapes influence species distributions, abundance trends, and community composition. I apply novel analytical tools to address my research questions.	Trees and bushes, home sweet home for warblers
Becky Fuller	University of Illinois	I grew up in a small town riding horses in 4-H and working in a veterinary clinic. I’ve always been interested in biology, but two key experiences lead me to my career. I took courses at Cedar Point Biological Field Station. There I met Dr. Tony Joern who hired me onto his field crew to study grasshopper community ecology. I caught the “science bug” and never looked back. After undergrad I worked with Dr. Anders Berglund on pipefish on the west coast of Sweden. There I developed my love for fish and aquatics. I feel very fortunate to have a job where I can do science and teach young, enthusiastic students.	Why so blue? The determinants of color pattern in killifish Part 1 & Part 2

My area of specialization is Molecular Biology, Biochemistry, and Genomics.	Cheaters in nature – when is a mutualism not a mutualism?
Ali Gephart	Bayfield High School	I graduated from Bayfield High School in 2012. After graduation, I attended UW-La Crosse for 2 years and then transferred to UW Madison where I graduated in 2016 with a degree in Communication Arts - Film/Radio/TV. I spent 5 years in Los Angeles trying my best to avoid the sun before moving back to the Midwest. I now live in Chicago and work as a Studio Mechanic (Local 476) on TV shows such as Chicago Med, The Chi and Force. I much prefer the climate here in Chicago, Southern California is simply too hot. Not to mention I couldn’t stand living so far away from one of the Great Lakes.	Lake Superior rhythms
Gena Gephart	Bayfield High School	After graduating from Bayfield High School, Gena attended UW-Madison where she got her degree in Communication Arts and Gender & Women’s Studies. After college Gena moved to Chicago to pursue standup comedy which people think is an art but is actually a science.	Lake Superior rhythms
Eben Gering	Michigan State University	One of the most exciting things I learned as a college student was that natural populations sometimes evolve very quickly. Biologists used to think evolution was too slow to be studied “in action”, so their research focused on evolutionary changes that occurred over thousands (or even millions) of years. I study feral animal populations to learn how rapid evolutionary changes help them survive and reproduce, without direct help from us.	Feral chickens fly the coop
Anne Giblin	Marine Biological Laboratory & Plum Island Ecosystems LTER	My major research interest has been on the cycling of elements in the environment, especially the biogeochemistry of nitrogen, sulfur, iron, and phosphorus. Much of my work has been focused in soils and sediments where element cycling takes place under different conditions of oxidation and reduction. Much of my current research focuses on the nitrogen cycle and has been centered on understanding how ecosystems respond to high nutrient inputs from wastewater and fertilizer.	Keeping up with the sea level
Cara Giordano	University of Virginia	My research in sexual selection focuses on the dewlap, a secondary sexual trait in the brown anole lizard. I investigate if variation in the characteristics of this ornament relates to the fitness of the individual expressing it. I am interested in how ecological relationships change over time, particularly under pressures of environmental transition, as well as the physiological mechanisms that underlie conservation concerns.	Is it dangerous to be a showoff?
Laura Gough	Towson University	When I was young, I was always happiest when I was outside. I loved to walk in the woods and observe insects, birds, and mammals and think about how they could live with the plants I encountered there. I trained to be a plant ecologist and am still interested in how plants interact with other organisms in the same habitat. I have been studying the arctic tundra for many years and love thinking about how arctic organisms survive and thrive and how they are responding as climate change progresses and the Arctic warms.	Which tundra plants will win the climate change race?
Kristine Grayson	University of Richmond, Victoria University of Wellington	I am an Associate Professor in the Biology Department and an HHMI BioInteractive Ambassador and facilitator with the Quantitative Undergraduate Biology Education and Synthesis (QUBES) project. My work on tuatara was conducted during a postdoc at Victoria University of Wellington funded by an NSF International Research Fellowship. One of my claims to fame is capturing the state record holding snapping turtle for North Carolina – 52 pounds! To read more about my interest in science from a young age, check out this article.	When a species can’t stand the heat
Skye Greenler	Colorado College & Purdue University	As a child I was always asking why; questioning the behavior, characteristics, and interactions of plants and animals around me. This love of discovery, observation, questioning, and experimentation led me to pursue a career in science. As a graduate student at Purdue I study the factors influencing oak regeneration after ecologically based timber harvest and prescribed fire. While my primary focus is ecological research, I love getting to leave the lab and bring science into classrooms to inspire the next generation of young scientists and encourage all students to be always asking why!	Is chocolate for the birds?
Stanley Gregory	Oregon State University	I am a professor emeritus. My research focuses on the analysis of processes and patterns that shape aquatic and terrestrial ecosystems at landscape scales.

Travis Hagey	Michigan State University, BEACON	Ever since I was a kid, I've been interested in animals and wanted to be a paleontologist. I even had a bunch of dinosaur names memorized to back it up! In college I discovered evolutionary biology, which drove me to apply for graduate school and become a scientist. There, I fell in love with comparative biomechanics, which combines evolutionary biology and mechanical engineering. Today I study geckos and their sticky toes, which allow them to scale surfaces like glass windows and tree branches.	Sticky situations: big and small animals with sticky feet

Charles Hopkinson	University of Georgia & Marine Biological Laboratory	I have been studying estuaries since graduate school and in collaboration with colleagues from around the world, but especially here at Georgia and in Louisiana and Massachusetts (MBL). Estuaries are the most productive natural ecosystems of the world because they receive nutrient and water subsidies from every land use upstream and because of tidal pumping. It’s their location relative to land inputs however that also makes them vulnerable to N-enrichment and eutrophication.	Urbanization and estuary eutrophication
Forrest Howk	Bayfield High School, OneEnergy Renewables	I grew up in Bayfield, Wisconsin. In high school, I partnered with various local organizations and my science teacher to complete an independent project looking at long-term boat traffic data as a proxy for changing ice seasons in the Bayfield Harbor of Lake Superior.

Kevin Lee	University of Texas - Austin	My research uses sound to study the underwater environment, including ocean boundaries, aquatic life, and objects in the ocean. Many of my interests focus on the seabed: marine sediments, seagrass and aquatic vegetation, infauna (worms and other invertebrate animals that live in the seabed sediment), and carbon burial. I also study the acoustic effects of gas bubbles in the sediment and in the water, as well as how sound interacts and bounces off underwater objects (both natural and human-made). Another application of my research is finding ways to reduce human-made underwater noise pollution.	The sound of seagrass
Laura Lilly	Scripps Institution of Oceanography, UC San Diego	My research focuses on zooplankton responses to El Niño events in the California Current. I completed a joint B.S. and M.S. degrees at Stanford University in Earth Systems, with an oceanography focus. In conjunction with those degrees, I researched tuna physiology. Prior to graduate school, I completed a California Sea Grant Fellowship with the West Coast Governors' Alliance and Ocean Observing Systems to connect oceanographic data to policymakers. In my non-research time, I love to surf, ride horses, run, travel to Baja California, write poetry, and promote low-waste lifestyles.	Crunchy or squishy? How El Niño events change zooplankton
Michael Martin	University of Maryland, Baltimore County & University of Arizona	I started my college career as an engineer, but after taking a zoology class I was hooked on biology. I was amazed by the millions of different types of animals that have lived, and currently live, on Earth. I needed to know how so many different types of animals evolved, and so I decided to study the process of speciation. I am currently working in a group of stream fish, called darters, to try and learn how differences in mating behavior might lead to new animal species. This work has led me to a more general interest in animal behavior that I now study in fruit flies as well.	Are you my species?
Erin McCullough	University of Western Australia	I am fascinated by morphological diversity, and my research aims to understand the selective pressures that drive (and constrain) the evolution of animal form. Competition for mates is a particularly strong evolutionary force, and I study how sexual selection has contributed to the elaborate and diverse morphologies found throughout the animal kingdom. Using horned beetles as a model system, I am interested in how male-male competition has driven the evolution of diverse weapon morphologies, and how sexual selection has shaped the evolution of physical performance capabilities.	Beetle battles
Remington Moll	Michigan State University	I am currently a graduate student. My research uses cutting-edge technologies such as GPS collars and camera-traps to study predator-prey interactions between large carnivores and their prey. I am excited about evaluating how ecological theory developed in "natural" areas like national parks applies to urban contexts. I grew up in the city and fell in love with nature and ecology in city parks. Although it comes with challenges, I believe that humans and large predators can peaceably coexist, even in and around cities. It is my goal to use the lessons learned from my research to help make that belief a reality.	City parks: wildlife islands in a sea of cement

To address these questions, I study traits that are at the interface of species interactions.	A tail of two scorpions
Matt Rowe	University of Oklahoma	My research in behavioral ecology uses integrative approaches to study coevolution between predators and prey. These dynamic interactions show remarkable sophistication, from ground squirrels using rattling they provoke in rattlesnakes to assess the body size and temperature of their reptilian enemies, to grasshopper mice capable of feeding on highly neurotoxic scorpions because of subtle modifications in the mouse’s peripheral nerves. My conservation biology research examines habitat selection and habitat requirements in vertebrates.	A tail of two scorpions
Leilei Ruan	Michigan State University & University of California, Berkeley	I study the effects of nitrogen fertilizers on greenhouse gas emissions, a project that will help to maximize crop productivity while reducing emissions. In another research project, I examine biofuel crops.

Karina Scavo Lord	Boston University	I am a marine ecology PhD candidate interested in the population demographics and genomics of reef corals living in marginal, non-reef environments, such as mangroves and seagrass meadows. As coral reefs decline worldwide, scientists are looking beyond the reef to coral communities growing in these non-reef environments, which may serve as climate refugia or as reservoirs of resilient or hardy coral individuals. To better understand if these habitats are important to reef recovery, I use empirical, theoretical, and molecular approaches.	Corals in a strange place
Doug Schemske	Michigan State University	The goal of my research is to characterize the mechanisms of adaptation. This requires information on both the ecological significance of putative adaptive traits as well as an understanding of their genetic basis. Such comprehensive studies are extremely difficult to accomplish; thus it is perhaps not surprising that our current knowledge of adaptation is inadequate. A central theme of my work is the link between temporal and spatial variation in ecological conditions and the adaptive differentiation of populations and species. I rely on ecological and genetic approaches to investigate the origin and maintenance of biological diversity.	Winter is coming! Can you handle the freeze?

Make way for mummichogs

Collecting mummichogs and other fish out of research traps.

The activities are as follows:

Salt marshes are important habitats and contain a wide diversity of species. These ecosystems flood with salt water during the ocean’s high tide and drain as the tide goes out. Fresh water also flows into marshes from rivers and streams. Many species in the salt marsh can be affected when the movement of salt and fresh water across a tidal marsh is blocked by human activity, for example by the construction of roads. These restrictions to water movement, or tidal restrictions, can have many negative effects on salt marshes, such as changing the amount of salt in the marsh waters, or blocking fish from accessing different areas.

Local managers are working to remove tidal restrictions and bring back valuable habitat. At the same time, scientists are working to study how the remaining tidal restrictions impact fish populations. To do this, they measure the number of fish found upstream of tidal restrictions, which is the side connected to the river’s freshwater but cut off from the ocean when the restriction is in place. By taking measurements before and after the restriction is removed, scientists can study the impacts that the restriction had on fish populations

Mummichogs are a small species of fish that live in tidal marshes all along the Atlantic coast of the United States.

Mummichogs are a small species of fish that live in tidal marshes all along the Atlantic coast of the United States. They can be found in most streams and marsh areas and are therefore a valuable tool for scientists interested in comparing different marshes. The absence of mummichogs in a salt marsh is likely a sign that it is highly damaged.

In Gloucester, MA, students participating in Mass Audubon’s Salt Marsh Science Project are helping Liz and Robert use mummichogs to examine the health of a salt march. In 2002 and 2003 Liz, Robert, and the students set traps upstream of a road, which was acting as a tidal restriction. These traps collected mummichogs and other species of fish. The day after they set the traps, the students counted the number of each fish species found in the traps.

Students participating in Mass Audubon’s Salt Marsh Science Project Count fish at Eastern Point Wildlife Sanctuary, Gloucester, MA

In December 2003, a channel was dug below the road to remove the tidal restriction and restore the marsh. From 2004 to 2007, students in the program continued to place traps in the same upstream location and collect data in the same way each year. Students then compared the number of fish from before the restoration to the numbers found after the restriction was removed. The students thought that once the tidal restriction was removed, mummichogs would return to the upstream locations in the marsh.

The birds of Hubbard Brook, Part II

In Part I, you examined patterns of total bird abundance at Hubbard Brook Experimental Forest. These data showed bird numbers at Hubbard Brook have declined since 1969. Is this true for every species of bird? You will now examine data for four species of birds to see if each of these species follows the same trend.

Red-eyed vireo in the Hubbard Brook Experimental Forest

The activities are as follows:

It is very hard to study migratory birds because they are at Hubbard Brook only during their breeding season (summer in the Northern Hemisphere). They spend the rest of their time in the southeastern United States, the Caribbean or South America or migrating between their two homes. Therefore, it can be difficult to tease out the many variables affecting bird populations over their entire range. To start, scientists decided to focus on what they could study—the habitat types at Hubbard Brook and how they might affect bird populations.

Hubbard Brook Forest was heavily logged and disturbed in the early 1900s. Trees were cut down to make wood products, like paper and housing materials. Logging ended in 1915, and various plants began to grow back. The area went through what is called secondary succession, which refers to the naturally occurring changes in forest structure that happen as a forest recovers after it was cut down or otherwise disturbed. Today, the forest has grown back. Scientists know that as the forest grew older, its structure changed: Trees grew taller, the types of trees changed, and there was less shrubby understory. The forest now contains a mixture of deciduous trees that lose their leaves in the winter (about 80–90%; mostly beech, maples, and birches) and evergreen trees, mostly conifers, that stay green all year (about 10–20%; mostly hemlock, spruce, and fir).

Richard and his fellow scientists already knew a lot about the birds that live in the forest. For example, some bird species prefer habitats found in younger forests, while others prefer habitats found in older forests. They decided to look carefully into the habitat preferences of four important species of birds—Least Flycatcher, Red-eyed Vireo, Black-throated Green Warbler, and American Redstart—and compare them to habitats available at each stage of succession. They wondered if habitat preference of a bird species is associated with any change in the bird populations at Hubbard Brook since the beginning of succession.

Least Flycatcher: The Least Flycatcher prefers to live in semi-open, mid-successional forests. The term mid-successional refers to forests that are still growing back after a disturbance. These forests usually consist of trees that are all about the same age and have a thick canopy at the top with few gaps, a relatively open area under the canopy, and a denser shrub layer close to the ground.
Black-throated Green Warbler: The Black-throated Green Warbler occupies a wide variety of habitats. It seems to prefer areas where deciduous and coniferous forests meet and can be found in both forest types. It avoids disturbed areas and forests that are just beginning succession. This species prefers both mid-successional and mature forests.
Red-eyed Vireo: The Red-eyed Vireo breeds in deciduous forests as well as forests that are mixed with deciduous and coniferous trees. They are abundant deep in the center of a forest. They avoid areas where trees have been cut or blown down and do not live near the edge. After an area is logged, it often takes a very long time for this species to return.
American Redstart: The American Redstart generally prefers moist, deciduous, forests with many shrubs. Like the Least Flycatcher, this species prefers mid-successional forests.

The birds of Hubbard Brook, Part I

The activities are as follows:

The Hubbard Brook Experimental Forest is an area where scientists have collected ecological data for many years. It is located in the White Mountains of New Hampshire. Data collected in this forest helps uncover environmental trends over long periods of time, such as changes in air temperature, precipitation, forest growth, and animal populations. It is important to collect data on ecosystems over time because these patterns could be missed with shorter observation periods or short-term experiments.

Richard Holmes is an avian ecologist who began this study because he was interested in how bird populations were responding to long-term environmental change.

Each spring, Hubbard Brook comes alive with the arrival of migratory birds. Many come from the tropics to take advantage of abundant insects and the long summer days of northern areas. In the spring, avian ecologists, or scientists who study the ecology of birds, also become active in the forest at Hubbard Brook. They have been keeping records on the birds that live in the experimental forest for over 50 years. These data are important because they represent one of the longest bird studies ever conducted!

Richard is an avian ecologist who began this study early in his career as a scientist. He was interested in how bird populations respond to long-term environmental changes at Hubbard Brook. Every summer since 1969, Richard takes his team of trained scientists, students, and technicians into the field to identify which species are present. Richard’s team monitors populations of over 30 different bird species. They count the number of birds that are in the forest each year and study their activities during the breeding season. The researchers wake up every morning before the sun rises and travel to the far reaches of the forest. They listen for, look for, identify, and count all the birds they find. The team has been trained to be able to identify the birds by sight, but also by their calls. Team members are even able to identify how far away a bird is by hearing its call!

The study area is located away from any roads or other disturbed areas. To measure the abundance, or number of birds found in the 10 hectare study area, the researchers used what is called the spot-mapping method. They use plastic flags on trees 50 meters apart throughout the study area to create a 50×50 meter grid. The grid allows them to map where birds are found in this area, and when possible, where they locate their nests. Using the grid the researchers systematically walk through the plot several days each week from early May until July, recording the presence and activities of every bird they find. They also note the locations of nearby birds singing at the same time. These records are combined on a map to figure out a bird’s territory, or activity center. At the end of the breeding season they count up the number of territories to get an estimate of the number of birds on the study area. This information, when paired with observations on the presence and activities of mates, locations of nests, and other evidence of breeding activity provide an accurate estimate for bird abundance. Finally, some species under close study, like American Redstart and Black-throated Blue Warbler, were captured and given unique combinations of colored bands, which makes it easier to track individuals.

By looking at bird abundance data across many years, Richard and his colleagues can identify trends that reveal how avian populations change over time.

Keeping up with the sea level

A view of salt marsh hay (Spartina patens) growing in a marsh

The activities are as follows:

Salt marshes are ecosystems that occur along much of the coast of New England in the United States. Salt marshes are very important – they serve as habitat for many species, are a safer breeding location for many fish, absorb nutrients from fertilizer and sewage coming from land and prevent them from entering the ocean, and protect the coast from erosion during storms.

Unfortunately, rising sea levels are threatening these important ecosystems. Sea level is the elevation of the ocean water surface compared to the elevation of the soil surface. Two processes are causing sea levels to rise. First, as our world gets warmer, ocean waters are getting warmer too. When water warms, it also expands. This expansion causes ocean water to take up more space and it will continue to creep higher and higher onto the surrounding coastal land. Second, freshwater frozen in ice on land, such as glaciers in Antarctica, is now melting and running into the oceans. Along the New England coast, sea levels have risen by 0.26 cm a year for the last 80 years, and by 0.4 cm a year for the last 20 years. Because marshes are such important habitats, scientists want to know whether they can keep up with sea level rise.

Researcher Sam Bond taking Sediment Elevation Table (SET) measurements in the marsh

When exploring the marsh, Anne, a scientist at the Plum Island Ecosystems Long Term Ecological Research site, noticed that the salt marsh appeared to be changing over time. One species of plant, salt marsh cordgrass (Spartina alterniflora), appeared to be increasing in some areas. At the same time, some areas with another species of plant, salt marsh hay (Spartina patens), appeared to be dying back. Each of these species of plants is growing in the soil on the marsh floor and needs to keep its leaves above the surface of the water. As sea levels rise, the elevation of the marsh soil must rise as well so the plants have ground high enough to keep them above sea level. Basically, it is like a race between the marsh floor and sea level to see who can stay on top!

Anne and her colleges measured how fast marsh soil elevation was changing near both species of plants. They set up monitoring points in the marsh using a device called the Sediment Elevation Table (SET). SET is a pole set deep in the marsh that does not move or change in elevation. On top of this pole there is an arm with measuring rods that record the height of the marsh surface. The SETs were set up in 2 sites where there is salt marsh cordgrass and 2 sites where there is salt marsh hay. Anne has been taking these measurements for more than a decade. If the marsh surface is rising at the same rate as the sea, perhaps these marshes will continue to do well in the future.

Does sea level rise harm Saltmarsh Sparrows?

Painting of the saltmarsh sparrow

The activities are as follows:

For the last 100 years, sea levels around the globe have increased dramatically. The cause of sea level rise has been investigated and debated. Data from around the world supports the hypothesis that increasing sea levels are a result of climate change caused by the burning of fossil fuels. As we warm the Earth, the oceans get warmer and polar ice caps melt. The dramatic increase in sea level that results could seriously threaten ecosystems and the land that humans have developed along the coast.

Salt marshes are plains of grass that grow along the east coast of the United States and many coasts worldwide. Salt marshes grow right at sea level and are therefore very sensitive to sea level rise. In Boston Harbor, Massachusetts, the NOAA (National Oceanic and Atmospheric Administration) Tide Gauge has measured a 21mm rise in sea level over the last 8 years. That means every year sea level has gone up an average of 2.6mm since 2008 – more than two and a half times faster than before we started burning fossil fuels! Because sea level is going up at such a fast rate, Robert, a scientist in Boston, became concerned for the local salt marsh habitats near his home. Robert was curious about what will happen to species that depend on Boston’s Plum Island Sound salt marshes when sea levels continue to rise.

Robert preparing his team for a morning of salt marsh bird surveys.

Robert decided to look at species that are very sensitive to changes in the salt marsh. When these sensitive species are present, they indicate the marsh is healthy. When these species are no longer found in the salt marsh, there might be something wrong. The Saltmarsh Sparrow is one of the few bird species that builds its nests in the salt marsh, and is totally dependent on this habitat. Saltmarsh Sparrows rely completely on salt marshes for feeding and nesting, and therefore their numbers are expected to decline as sea levels rise and they lose nesting sites. Robert heard that scientists studying Connecticut marshes reported the nests of these sparrows have been flooded in recent years. He wanted to know if the sparrows in Massachusetts were also losing their nests because of high sea levels.

For the past two decades Robert has kept track of salt marsh breeding birds at Plum Island Sound. In his surveys since 2006, Robert counted the number of Saltmarsh Sparrows in a given area. He did these surveys in June when birds are most likely to be breeding. He used the “point count” method – standing at a center point he measured out a 100 meter circle around him. Then, for 10 minutes, he counted how many and what kinds of birds he saw or heard within and just outside the circle. Each year he set up six count circles and performed counts three times in June each year at each circle. Robert also used sea level data from Boston Harbor that he can relate to the data from his bird surveys. He predicted that sea levels would be rising in Plum Island Sound and Saltmarsh Sparrow populations would be falling over time.

History of Data Nuggets

Because Data Nuggets originated from a partnership of teachers and scientists, they address both the needs of scientists to share their research broadly while developing their communication skills, and of teachers who need resources that address education reform and teach science in an authentic way.

Data Nuggets are designed and developed by Elizabeth Schultheis and Melissa Kjelvik from Michigan State University. They have been under development since 2011 and originated through conversations between science teachers and graduate students during the NSF GK-12 project “New GK-12: Using the STEM Dimensions of Bioenergy Sustainability to Bring Leading-edge Graduate Research to K-12 Learning Settings”. This unique opportunity for collaboration between teachers and scientists led to the creation of teacher-inspired resources. Teachers shared that they were lacking educational resources that helped their students practice working with real, messy data like that collected during classroom inquiry-based projects. Graduate students in the sciences, not surprisingly, have lots of practice working with messy data and surprising results. Through this collaboration, Data Nuggets were created to bring real data from current and ongoing research into the classroom and take students through the process of science, from the inception of ideas to the analysis and interpretation of data.

Melissa Kjelvik and teacher Connie High working together to collect scientific data.

From 2013-2015, Data Nuggets were funded with seed grants from the NSF BEACON Center Study of Evolution in Action. These funds allowed us to greatly expand Data Nuggets as a resource, with activities now being developed in response to workshops held across the BEACON consortium. The funding has also provided opportunities to collaborate with science educators at Understanding Science (UCMP), National Institute for Mathematical and Biological Synthesis (NIMBioS), and Biological Sciences Curriculum Study (BSCS) to further refine the template and to align Data Nuggets with current science standards and reform, making them easier to integrate into existing curriculum.

Data Nuggets are currently funded by a 4-year NSF DRK-12 grant, awarded to MSU and BSCS in 2015, to conduct a research study to evaluate the effectiveness of integrating Data Nuggets into science curriculum. This research will help to determine whether these short activities can increase the mathematical skills of students and their ability to think scientifically and support claims using data.

Liz Schultheis working with teachers to collect herbivory data.

We will continue to develop and revise Data Nuggets to help teachers bring sets of data from graduate student research into their classroom, and help students become comfortable working with messy data and unexpected results. Data Nuggets have gone through an iterative development process, where materials developed by scientists were used in the classroom and modified based on teacher and student experiences and feedback. We continue to present Data Nuggets at national and local education conferences where teachers and science educators can provide feedback on the structure and content of each activity. Our innovative and iterative development approach has led to a product that teachers and students find easy to work with and integrate into existing curriculum.
