These data are part of the Gulf Watch Alaska (GWA) long-term monitoring program and contain diet data from Black-legged Kittiwakes (BLKI), Rhinoceros Auklets (RHAU), and Tufted puffins (TUPU) located on Middleton Island in Prince William Sound, Gulf of Alaska. The first table consists of information on seabird diet samples including the sampling method and number of prey types identified per sample ("seabirdDiets_foodSample_middletonIsland.csv"). The second table is similar to the first table, however, the samples have been subdivided by individual prey species ("seabirdDiets_samplePrey_middletonIsland.csv"). The third table consists of information specific to sampled prey items, such as prey taxa identification...
The primary objective is to provide guidance to conservation agencies and programs such as Texas Parks and Wildlife Department, Louisiana Department of Fisheries and Wildlife, U.S. Fish and Wildlife Service Region 2 and 4 National Wildlife Refuges, and U.S. Fish and Wildlife Service Migratory Bird Office Region 2 to focus banding activities (i.e., where and when) and minimum sample sizes necessary to meet harvest management objectives for mottled ducks. A secondary objective is to investigate alternate marking techniques (e.g., PIT tags, NANO tags) to supplement or replace assessments derived from band recoveries. The banding needs assessment will be a two part analysis. The first part will use multi-state simulation...

The mottled duck, a focal species for the Gulf Coast Prairie Landscape Conservation Cooperative, is one of only a few duck species adapted to breeding in southern marshes. A major part of its population spends its entire life cycle within a relatively small coastal area in eastern Texas and western Louisiana. This is a thriving part of the Mississippi and Central Flyways, two of four major waterfowl migration routes in North America. In recent years, the mottled duck’s habitat and surrounding areas have been compromised by urbanization, agricultural development, and changes to the area’s hydrology affecting coastal wetlands. The latter threat includes the ramifications of climate change, such as sea level rise and...

This data package contains digital images, survey location logs and a summary tabulation from carcass survey conducted at walrus haulouts in Alaska. A summary of image collection times is provided as a tabular file. The images are considered sensitive. They are archived at the U.S. Geological Survey, Alaska Science Center (a USGS Trusted Digital Repository). At this time, only this metadata record describing the data, an image inventory table, and a satellite (GNSS) log are publicly accessible.

The North American Breeding Bird Survey (BBS) is an ongoing effort that has collected data on bird populations and trends since 1966. The Rainwater Basin Joint Venture (RWBJV) has used this data from 2005 to 2010 to create species distribution models (SDMs) for target bird populations within Nebraska. Species targeted by this modeling include Dickcissel (DICK), Eastern Meadowlark (EAME), Grasshopper Sparrow (GRSP), and Western Meadowlark (WEME). These species were identified as high-priority Planning Species by the RWBJV Landbird Plan. The SDMs created by this analysis will be used to better inform conservation efforts throughout the state. For this analysis we used the following variable data: Missouri Resource...

Sea level rise caused by climate change is an ongoing phenomenon and a concern both locally and worldwide. Low-lying coastal areas are particularly at risk to flooding and inundation, affecting a large proportion of the human population concentrated in these areas as well as natural communities-particularly animal species that depend on these habitats as a key component of their life cycle. While more local, state, and federal governments have become concerned with the potential effects that predicted sea levels will have on their communities and coastal landscapes, more information is needed on the potential effects that changes in sea level will have on coastal habitats and species.

This dataset is one table with results of tests to determine exposure of Chukchi Sea polar bears to a suite of pathogens. Results are serological tests for antibodies and tests of fecal samples for presence of parasites. Serologic assays were conducted for Toxoplasma gondii, Neospora caninum, Francisella tularensis, Coxiella burnetii, Leptospira spp., Brucella canis, Brucella abortus/suis, and canine distemper virus. Parasitology analyses were conducted for presence of Giardia cysts and Cryptospiridium oocysts in fecal samples. Polar bears were sampled on sea ice in the Chukchi Sea between mid-March and early May 1987-1994 and 2008-2017. The dataset includes relevant information about the bears that were captured...

These were data collected from polar bears from the southern Beaufort Sea during the spring between 2004 and 2016. Data include individual bear identification, age and sex class, capture date, capture year, open water season lengths, melt season length, and diet composition (expressed as a percentage of prey species). These data were used to determine whether polar bear diets have recently changed or remained stable over time.

This data release is composed of seven datasets regarding colonial seabirds and forage fish at two seabird nesting colonies on Gull and Chisik Islands in lower Cook Inlet, Alaska. These data were collected to detect changes in the breeding population of Black-legged Kittiwakes and Common Murres on two nesting colonies in lower Cook Inlet and to compare those counts to baseline counts from 1995-1999. They are part of an ongoing study in lower Cook Inlet, Alaska to assess the recent status of forage fish and seabirds (2000-2020).
This project will expand abundance & distribution models for seabirds, currently underway in Aleutian Is region (USFWS-funded project under Survey, Monitoring & Assessment program) to the greater ABSI-LCC region, and integrate 2013 seabird surveys into the analysis. In particular, this expanded effort would first focus on the North Bering Sea/Bering Strait/southern Chukchi region, which has greatest potential for increased vessel traffic and development. Using at-sea survey data, colony data, and environmental parameters, Tern Again Consulting (Dr. M. Renner) is developing seasonal species-specific models of seabird distribution in the Aleutian Islands region for use in a shipping risk assessment. The resulting...
