Field observations of extreme sedimentation events
March 22, 2016

Sediment deposition serves an important role in the long-term maintenance of coastal marshes. USGS investigates the mechanisms of coastal marsh elevation regulation to help predict marsh sediment requirements under various sea level rise scenarios. ...

Understanding host-parasite and parasite consumer trophic relationships
March 22, 2016

Marine reserves and protected areas in the U.S. Virgin Islands and Puerto Rico encompass a variety of tropical ecosystems, including coral reefs, mangroves, and seagrass beds, but questions remain regarding how effective these areas are at preserving and protecting the habitats and species they encompass. USGS and collaborators address this question by examining the biodiversity and food web...

Sediment Elevation Table assembly and field shelter, Dongting Lake, China
March 18, 2016

Dongting Lake, one of the wetlands that make up the floodplains of China's Yangtze River, is important habitat for migratory waterfowl and other wildlife. However, the re-engineering of the water way and the intensification of agricultural practices has contributed to changes in hydrology and sedimentation. USGS and partners from China are assessing the potential impact of these...

A Decision Support Tool for Repatriation of Aquatic Fauna: A Case Study Involving the Striped Newt (Notophthalmus perstriatus) a
April 17, 2015

The Striped Newt is a small salamander found in xeric habitats (e.g., scrub, sandhill, dry flatwoods) of the lower coastal plain and northern peninsular Florida. Though once considered "common," they are currently a candidate species for federal listing. ...

Catawba rhododendron blooming at Round Bald, NC
August 11, 2016

“From the mountains to the coast, the southeastern U.S. contains ecosystems that harbor incredible biodiversity. Many of those ecosystems are already highly at risk from urbanization and other human land-use change. Identifying the ecosystems at risk from climate change will help inform conservation and management to ensure we don’t lose that biodiversity.” (Jennifer Constanza, report author)

Grizzly Bears and Wolves
August 10, 2016

Natural and cultural areas that will remain similar to what they are today -- despite climate change -- need to be identified, managed and conserved as “refugia” for at-risk species, according to a study published today in PLOS One. The study sets out, for the first time, specific steps to help identify and manage these more resilient and climate-stable havens for plants, animals and fishes.

Landsat 8
July 18, 2016

In western North America, mountain pine beetles infest and ravage thousands of acres of forest lands. Landsat satellites bear witness to the onslaught in a way that neither humans nor most other satellites can.
