Conserving grizzly bear populations is a significant challenge for wildlife managers throughout North America. Much fruitful research has been conducted on the biology of grizzlies, but the human dimensions of bear management remain poorly understood. This imbalance has created conflicts between management agencies and local inhabitants that can jeopardize ecosystem management and planning programs in which grizzlies often feature as key components. Broadly, the goal of this study was to understand how and why such conflicts occur. Qualitative data analysis methods and the policy sciences' interdisciplinary problem analysis framework, along with insights from adaptive governance and co-management concepts, resilience...

Climate change is expected to worsen the harmful effects of invasive species on native wildlife. This presents a growing conservation challenge for invasive species managers in the southeastern United States where thousands of invasive species exist. While many of these invasive species currently have relatively small ranges in the southeastern U.S., climate change may allow them to expand into new regions. To effectively plan and respond to the redistribution of invasive species, it is crucial to coordinate existing information and identify future information needs across regional boundaries. The ultimate goal of this project is to improve invasive species management in the face of climate change by establishing...
Climate change is affecting species and ecosystems across the Northeast and Midwest U.S. Natural resource managers looking to maintain ecological function and species persistence have requested information to improve resource management in the face of climate change. Leveraging the research that has already been supported by the Northeast Climate Adaptation Science Center and its partners, this project used the latest modeling techniques combined with robust field data to examine the impact of specific climate variables, land use change, and species interactions on the future distribution and abundance of species of conservation concern. An interdisciplinary team worked to understand the mechanisms that are driving...

Remote camera stations were set up in Lassen Volcanic National Park from August to October 2017 and June to September 2018 to document occurrence of mesocarnivores and other wildlife. 126 cameras were set up at 32 primary sampling units (clusters of two to four cameras) throughout the park. Random locations for primary sampling units were chosen using a 3-km sampling grid over the park area. The dataset contains all species observed within the study time-frame, the date and time of observation and the number of individuals detected as well as identification for individual locations, cameras and images. Of the three target species of conservation concern (Pacific fisher (Pekania pennanti), Pacific marten (Martes...

Northeastern boreal forests are an important habitat type for many wildlife species, including migratory birds and moose. These animals play vital roles in the boreal forest ecosystem, are a source of pleasure for bird and wildlife watchers, and contribute to tourism revenue for many communities. However, moose and migratory birds are thought to be particularly vulnerable to the impacts of climate change. For example, in New York’s Adirondack Park system, five species of boreal birds have shown occupancy declines of 15% or more. Meanwhile, moose are threatened by winter ticks that thrive in warmer climates and spread disease. A 2018 New York Department of Environmental Conservation (NYDEC) report found that there...

Researchers with the North Central Climate Science Center have made substantial progress in assessing the impacts of climate and land use change on wildlife and ecosystems across the region. Building on this progress, researchers will work with stakeholders to identify adaptation strategies and inform resource management in the areas that will be most affected by changing conditions. There are several components of this project. First, researchers will use the Department of Interior “resource briefs” as a mechanism to communicate information to resource managers on climate and land use change and their impacts to resources. These briefs will support coordinated management of ecosystems that contain public, private,...

OBIS-USA brings together marine biological occurrence data – recorded observations of identifiable marine species at a known time and place, collected primarily from U.S. Waters or with U.S. funding. Coordinated by the Science Analytics and Synthesis (SAS) Program of the United States Geological Survey (USGS), OBIS-USA, strives to meet national data integration and dissemination needs for marine data about organisms and ecosystems. OBIS-USA is part of an international data sharing network (Ocean Biodiversity Information System, OBIS) coordinated by the Intergovernmental Oceanographic Commission, of UNESCO (United Nations Educational, Science and Cultural Organization) International Oceanographic Data and Information...

This report summarizes the inventory of mammals of the five park units comprising the Arctic Network (ARCN) of the National Park Service, Alaska Region, between 2000 and 2003. This study was part of a cooperative effort of the Beringian Coevolution Project at the Museum of Southwestern Biology, University of New Mexico, and the ARCN Inventory and Monitoring Program of the National Park Service, Alaska division. We begin documenting the approximately 39 species of mammals that live in ARCN, with a primary focus on small mammals (i.e., shrews, voles, lemmings, weasels, porcupine, squirrels, and hares). This survey resulted in more than 3,000 primary specimens comprising 23 species. Small mammal abundance varied considerably...

There are comparatively few fossils that document the presence of the Pleistocene western camel (Camelops hesternus) in the unglaciated regions of Alaska and Yukon, northwestern North America (eastern Beringia). It has been previously reported on the basis of stratigraphic and radiocarbon data that this species was present within this region from the Sangamonian interglaciation (Marine Isotope Stage (MIS) 5) through the Last Glacial Maximum (LGM, MIS 2). However, the continued presence of western camel through the LGM is at odds with its ecological preferences as inferred from more southerly parts of the continent. Here we report 43 new radiocarbon dates on 34 western camel fossils from Alaska and Yukon, including...

The fundamental niche of a species is rarely if ever realized because the presence of other species restricts it to a narrower range of ecological conditions. The effects of this narrower range of conditions define how resources are partitioned. Resource partitioning has been inferred but not demonstrated previously for sympatric ursids. We estimated assimilated diet in relation to body condition (body fat and lean and total body mass) and reproduction for sympatric brown bears (Ursus arctos) and American black bears (U. americanus) in south-central Alaska, 1998?2000. Based on isotopic analysis of blood and keratin in claws, salmon (Oncorhynchus spp.) predominated in brown bear diets (>53% annually) whereas black...

Harbor porpoise, Phocoena phocoena vomerina, in Cook Inlet, Alaska, are managed as part of the Gulf ofAlaska (GOA) stock. It is not known if this population is distinct from porpoise in the GOA stock found outside Cook Inlet. No long- term dedicated studies of harbor porpoise have occurred in Cook In let. The objective here is to provide a summary of occurrence in Cook Inlet derived from archaeological data, anecdotal reports, and systematic surveys. Maps were created for each dataset. Therefore, each of these estimates is likely biased downward. In the last decade the region has seen expansion of the Port of Anchorage, proposals to build a bridge crossing Knik Arm, plans to develop mining operations and supporting...
