Connectivity among coral communities influences the probability of speciation and contributes to their ability to adapt to natural and anthropogenic stressors. Results from this study will enhance our understanding of Gulf ecosystems with regional conservation initiatives to inform the restoration of degraded deepwater coral communities and preserve long-term viability of coastal ecosystems.

Deep-sea canyons are complex environments encompassing a range of benthic habitats, including soft sediments along the axis of the canyon, and hard substrates along the canyon walls.

Pregnant polar bears enter maternity dens in October/November, give birth to cubs in December/January, and exit dens in March/April. Historically, most polar bears from the Southern Beaufort Sea (SBS) population constructed maternity dens on the sea ice. Over the last three decades, as sea ice has become thinner and prone to fragmentation, there has been a landward shift in the distribution of...

A massive die-off of Common Murres was documented in the Gulf of Alaska (GOA) during the fall and winter of 2015-2016 in association with a record-breaking marine heat wave in the GOA.

Reclamation on lands impacted by energy development is complicated and extremely challenging in arid environments due to unstable soils, exotic species, and low and variable precipitation. The reclamation tactics employed by energy operators vary widely and outcomes can differ across plant communities and soil types. In order to address the knowledge gaps regarding how to successfully and...

Widespread shale oil and gas (unconventional oil and gas, UOG) has only recently begun and many gaps in our knowledge of its potential effects to freshwaters exist.

Crude oil or oil distilled product (e.g. gasoline, diesel fuels, jet fuels) spills can occur during oil exploration, production, and transportation activities. Environmental impacts of spills are complex and can be difficult to assess. The chemical makeup of oil and oil products is diverse which affects oil behavior (e.g. volatilization, sinking). Oil degradation and fate are also influenced by...

Through the Changing Arctic Ecosystems (CAE) Initiative, the U.S. Geological Survey (USGS) is informing key resource management decisions by better understanding how wildlife populations of special interest to the Department of the Interior (DOI) are responding to rapid physical changes in the Arctic. Below are some examples of how CAE research is informing decision-making for oil and gas leasing...

Federal resource managers in the Williston Basin need to understand how the recent expansion of oil and gas development is affecting a range of natural resources. The Bakken Federal Executive Group (BFEG), a group of representatives from over a dozen federal and tribal agencies, called for a report that synthesizes existing information about the potential impacts from energy development. The BFEG...

Extraction of oil and gas via unconventional methods is becoming an important aspect of energy production worldwide. Studying the effects of this development in countries where these technologies are being widely used may provide managers in other oil producing parts of the world with some insight in terms of concerns associated with development. Rapid increases in energy development in North...

The recent expansion of unconventional oil and gas development in the Williston Basin of North America has raised concerns among managers about potential negative effects of such development on grassland birds. Others, however, have argued that agricultural land use in the region has had a much larger impact and that energy development may be a comparatively small stressor for grassland birds...

The U.S. Forest Service defines sensitive species as species that need special management to maintain and improve their status on National Forests and Grasslands, and prevent a need for listing under the Endangered Species Act. The Sprague’s pipit and Baird’s sparrow are listed as sensitive species in the Northern Region of the U.S. Forest Service. These species require large patches of native...
