South Atlantic Conservation Blueprint Version 2.0

The South Atlantic Conservation Blueprint is a living spatial plan to conserve natural and cultural resources for future generations. It identifies shared conservation priorities across the South Atlantic region. The second iteration of the Blueprint, Version 2.0, was released in July 2015. It was a completely data-driven plan based on ecosystem indicator models for terrestrial, freshwater, and marine environments, as well as a connectivity analysis. Blueprint 2.0 used a 200 m spatial scale. With Version 2.0, the total number of people actively involved in developing the Blueprint grew to more than 400 individuals from over 100 organizations.

Mercury Concentrations, Diet, and Gut Microbiota Diversity of Southern Beaufort Sea Polar Bears, 2008-2019

This dataset is two tables with data collected and derived from polar bears sampled in Alaska’s southern Beaufort Sea during 2008-2019. Collected data includes demographic and morphometric information and derived data includes mercury concentrations in hair samples. Ancillary data includes gut microbiome abundances, diversity indices, calculated body condition, and the proportions of prey species detected in individual bear diets. These data were used to determine whether gut microbiota community richness and diversity were associated with diet-acquired mercury.

Synthesis of high and low marsh habitat mapping, vulnerability and responses to sea-level rise in the South Atlantic region

Marshes are a critical habitat for a diversity of fauna and the ecological functioning of the coast. Despite their renowned vulnerability, uncertainty of wetland responses to sea-level rise remains a pervasive concern in coastal science and management, particularly for coastal resource conservation and climate change adaptation. Inventorying and mapping marsh dynamics have emerged as high priorities for assessing regional vulnerability to sea-level rise, requiring synthesis of existing marsh habitat maps, improved methodology for their continual monitoring, and assessment of their vulnerability with modeling and analysis. Multispectral remote sensing (balloon-, airplane- and satellite-based), LiDAR, NWI wetland...

Catch-Per-Unit-Effort (CPUE), Banding, and Morphometric Data Collected During Nocturnal Mist-Netting Sessions to Evaluate Trends and Variability Among Storm-Petrels of the California Channel Islands (1994-2018)

Herein we provide a comprehensive database of storm-petrel (Hydrobates spp.) morphometrics, banding, and associated mist-netting data collected within Channel Islands National Park (CHIS) from 1994 to 2018. The most abundant storm-petrel species in CHIS, the ashy storm-petrel (Hydrobates homochroa; ASSP), was the focal species in most mist-netting efforts, but data also were recorded for Leach’s (H. leucorhoa; Adams et al. 2016) and black (H. melania) storm-petrel. Collecting and compiling recent and historic mist-net datasets into one database has facilitated summary analyses of important components of these data including species morphometrics, recapture rates, and incubation patch condition (a potential indicator...

These data are estimates of the proportional contributions of bearded seal, beluga whale, bowhead whale, and ringed seal to the diets of southern Beaufort Sea polar bears. Fat biopsy samples were collected from polar bears captured or biopsy darted along the north coast of Alaska or on offshore ice during March, April, and May from 2004 to 2016. Fatty acid data of the above four prey species were compiled from online sources (Bromaghin et al. 2015ab, USGS 2021) and one private source that has been used in several polar bear diet studies (Thiemann et al. 2008). Diet composition was estimated from polar bear adipose tissue fatty acid composition data (USGS 2023) using three methods: the original quantitative fatty...
