Overview Fishes of the Adirondack Park face numerous challenges. Summer Suckers are the only endemic vertebrate yet have suffered major range reductions, so we are analyzing their genome, body shape, and spawning timing to verify their uniqueness and current range. Warming patterns are expected to shift their spawning earlier, potentially intersecting with their recent ancestor (White Suckers) to create hybridization and reduced reproductive success. Minnows are more diverse in the Adirondacks, and our analyses suggest that they show three major distributional patterns that reflect post-glacial colonization and temperature preferences. We are analyzing data from hundreds of lakes to discern the rules that structure...

There is growing evidence that headwater stream ecosystems are especially vulnerable to changing climate and land use, but managers are challenged by the need to address these threats at a landscape scale, often through coordination with multiple management agencies and landowners. This project sought to provide an example of cooperative landscape decision-making by addressing the conservation of headwater stream ecosystems in the face of climate change at the watershed scale. Predictive models were built for critical resources to examine the effects of the potential alternative actions on the objectives, taking account of climate effects and examining whether there are key uncertainties that impede decision making....

Appropriate ecological indicators of climate change can be used to measure concurrent changes in ecological systems, inform management decisions, and potentially to project the consequences of climate change. However, many of the available indicators for North American birds do not account for imperfect observation. We proposed to use correlated-detection occupancy models to develop indicators from the North American Breeding Bird Survey data. The indicators were used to test hypotheses regarding changes in range and distribution of breeding birds. The results will support the Northeast Climate Science Center’s Science Agenda, including the science priority: researching ecological vulnerability and species response...

USFWS Landscape Conservation Cooperatives (LCCs) throughout the Mississippi River Basin (MRB) have identified high nutrient runoff, a major contributor to Gulf hypoxia, and declines in wildlife populations (especially grassland and riparian birds), as conservation challenges requiring collaborative action. This project aimed to develop a spatial decision support system (DSS) to address these issues. The DSS was designed to identify MRB watersheds where application of conservation practices can (1) reduce nutrient export to the Gulf hypoxia zone and (2) enhance conservation for grassland and riparian birds, based on (3) identifying landowners willing and capable of implementing these practices. The DSS is expected...

Forests in the eastern United States are changing in response to ecological succession, tree harvest, and other disturbances and climate change has the potential to further change these forests. We predicted the distribution and abundance of common tree species across portions of the eastern U.S. under alternative climate scenarios that varied in the amount of warming by the end of the century from 1.1 to 4.2 degrees celsius. We used a forest landscape change model to forecast changes in tree abundances and distribution in the North Atlantic region of the U.S. while accounting for climate change, succession, and harvest. We then considered a broader region of the U.S. and combined our results with results from previous...

Prairies were once widespread across North America, but are now one of the most endangered and least protected ecosystems in the world. Agriculture and residential development have reduced once extensive prairies into a patchwork of remnant prairies and “surrogate” grasslands (e.g., hayfields, planted pastures). Grassland ecosystems and many grassland-dependent birds are also particularly vulnerable to rapid shifts in climate and associated changes in drought and extreme weather. The Central Flyway is a vast bird migration route that comprises more than half of the continental U.S., and extends from Central America to Canada, and harbors the greatest diversity of grassland birds in North America. Throughout this...

The fast pace of change in coastal zones, the trillions of dollars of investment in human communities in coastal areas, and the myriad of ecosystem services natural coastal environments provide makes managing climate-related risks along coasts a massive challenge for all of the U.S. coastal states and territories. Answering questions about both the costs and the benefits of alternative adaptation strategies in the near term is critical to taxpayers, decision-makers, and to the biodiversity of the planet. There is significant public and private interest in using ecosystem based adaptation approaches to conserve critical significant ecosystems in coastal watersheds, estuaries and intertidal zones and to protect man-made...

Prairie ecosystems and the grassland birds that rely on them for habitat may be particularly vulnerable to rapid changes in climate. Extensive portions of prairie have already been lost due to agriculture and urbanization, and as a result grassland birds have declined more than any other bird group in the last four decades. Now, climate change could exacerbate existing threats to these birds as temperatures in certain prairie ecosystems are expected to rise and extreme weather events, such as drought, could become more common. The goal of this project was to develop a framework to identify demographic sensitivities and assess the vulnerability of grassland bird species to future climate change. To do so, the researchers...

Climate change is expected to alter stream temperature and flow regimes over the coming decades, and in turn influence distributions of aquatic species in those freshwater ecosystems. To better anticipate these changes, there is a need to compile both short- and long-term stream temperature data for managers to gain an understanding of baseline conditions, historic trends, and future projections. Unfortunately, many agencies lack sufficient resources to compile, conduct quality assurance and control, and make accessible stream temperature data collected through routine monitoring. Yet, pooled data from many sources, even if temporally and spatially inconsistent, can have great value both in the realm of stream temperature...

A number of large-scale mapping projects have been completed in the U.S., and several cover all or some parts of the footprint of the Northeast Climate Science Center (NE CSC). These include maps by the Southeast GAP Analysis (SEGAP) program, the national LANDFIRE program, NatureServe, and The Nature Conservancy. These mapping projects represent a major step forward in describing the current extent of ecosystems on the landscape, and provide resource management agencies and organizations with unprecedented access to spatial information on these systems. In a number of cases, the ranges of these maps overlap. As a result, staff of resource management agencies and organizations are faced with trying to determine how...

This project addressed regional climate change effects on aquatic food webs in the Great Lakes. We sought insights by examining Lake Erie as a representative system with a high level of anthropogenic impacts, strong nutrient gradients, seasonal hypoxia, and spatial overlap of cold- and cool-water fish guilds. In Lake Erie and in large embayments throughout the Great Lakes basin, this situation is a concern for fishery managers, as climate change may exacerbate hypoxia and reduce habitat volume for some species. We examined fish community composition, fine-scale distribution, prey availability, diets, and biochemical tracers for dominant fishes from study areas with medium-high nutrient levels (mesotrophic, Fairport...

Spruce-fir forests and associated bird species are recognized as some of the most vulnerable ecosystems and species to the impacts of climate change. This work capitalized on a rich suite of long-term data from these ecosystems to document recent trends in these forests and their associated bird species and developed tools for predicting their future abundance under climate change. Findings from this work indicate declining trends in the abundance of spruce-fir obligate birds, including Bicknell’s Thrush, across the Lake States and New England. In contrast, montane spruce-fir forests in the White and Green Mountains of New England exhibited patterns of increasing abundance, potentially due to their recovery from...

Overview This project examines the ecological impacts of several introduced and expanding forest insects and diseases on forest habitats across the northeastern US and upper Lake States region. To address these novel threats, this work applies large-scale, co-developed experimental studies documenting impacts of ash mortality from emerald ash borer on lowland black ash communities in the Lake States and northern hardwood forests in New England; regional assessments of the impacts of the climate change-mediated expansion of southern pine beetle into northeastern pine barren communities; and ecological characterizations of areas experiencing suppression efforts to reduce the spread of the introduced Asian long-horned...

Overview Climate change is likely to impact erosion rates, the magnitude and frequency of extreme rainfall/mass wasting events, and the accumulation of sediment in coastal areas. However, long-term rates of erosion and sediment delivery to coastal systems are poorly constrained and there is limited understanding of the relative effects of climate change versus land-use change on these processes. Furthermore, existing instrumental and historical observations are inadequate for constraining the frequency of extreme events and evaluating the potential for changes in the magnitude and frequency of these events through time. This project will bolster two distinct but related research projects: (1) an ongoing study...

The number of fish collected in routine monitoring surveys often varies from year to year, from lake to lake, and from location to location within a lake. Although some variability in fish catches is expected across factors such as location and season, we know less about how large-scale disturbances like climate change will influence population variability. The Laurentian Great Lakes in North America are the largest group of freshwater lakes in the world, and they have experienced major changes due to fluctuations in pollution and nutrient loadings, exploitation of natural resources, introductions of non-native species, and shifting climatic patterns. In this project, we analyzed established long-term data about...

Many inland waters across the United States are experiencing warming water temperatures. The impacts of this warming on aquatic ecosystems are significant in many areas, causing problems for fisheries management, as many economically and ecologically important fish species are experiencing range shifts and population declines. Fisheries and natural resource managers need timely and usable data and tools in order to understand and predict changes to lakes and their biota. A previous Northeast CSC-funded project modeled lake temperatures to help state agencies in the Midwest understand trends in walleye and largemouth bass populations and predict lake-specific fish populations under future climate scenarios. These...

Coastal National Wildlife Refuges (NWRs) provide a myriad of beneficial services, including buffering storm surge, improving water quality, supporting commercial fisheries, and providing habitat for imperiled wildlife and plants. Yet in the last century, coastal ecosystems in the eastern U.S. have been severely altered by human development activities as well as sea-level rise and more frequent extreme events related to climate change. These influences threaten the goods and services provided by NWRs and pose decision-making challenges for refuge managers. The purpose of this project was to explore how structured decision-making – a formal, systematic method for analyzing decisions – could help NWR staff make informed...

The goal of this project is to identify statistical trends in observed and simulated maximum, minimum and base (mostly groundwater contribution during low flow months) flows in the Northeast Climate Science Center domain during the 20th and 21st century, assess the temporal (annual and seasonal) and spatial distribution of the trends, and evaluate the impact of warmer climates on the statistical properties of streamflows (mean and variance). A secondary goal is to determine what GCMs best represent the observed climatology of the region using statistical metrics. Base and minimum flows are vital for fish ecosystem functioning and for riparian vegetation. Climate projections indicate summers will get warmer and drier...

The Northeast United States and Atlantic Canada share many of the same types of forests, wetlands, and natural communities, and from a wildlife perspective the region is one contiguous forest. However, resources are classified and mapped differently on the two sides of the border, creating challenges for habitat evaluation, species modeling, and predicting the effects of climate change. To remedy this, ecologists from The Nature Conservancy collaborated with a committee of scientists from various Canadian institutions to produce the first international map of terrestrial habitats for northeast North America. The project used extensive spatial data on geology, soils, landforms, wetlands, elevation and climate. Additionally,...

In 2010, 39 percent of the U.S.population lived near the coast. This population is expected to increase by 8 percent from 2010 to 2020. Coastal regions are also home to species and habitats that provide critical services to humans, such as wetlands that buffer coasts from storms. Therefore, sea-level rise and the associated changes in coastlines challenge both human communities and ecosystems. Understanding which coastal lands will be vulnerable to sea-level rise is critical for policy makers, land-use planners, and coastal residents. Focusing on the coastal region from Virginia to Maine, researchers examined a range of different possible sea-level rise scenarios, combined with information on features of the coastal...
