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. ...

Generic Project Picture
January 6, 2004

Knowing the interactions of ground water and river water can help reduce the fluctuation of water supplies in alluvial (sediment-deposit) river basins.

To develop general principles of these interactions in order to identify and analyze them, the USGS is reviewing the results of the numerous studies of these interactions in Pacific Northwest basins. The review will describe common...

Did you know that tree canopy cover can be measured from space? The Moderate Resolution Imaging Spectroradiometer (MODIS) sensor onboard NASA’s Terra and Aqua satellites can do just that by providing data that are used to calculate Leaf Area Index (LAI). LAI is a measurement of green leaf area in broadleaf tree canopies and needle surface area in coniferous tree canopies. This data visualization...

New research from the U.S. Geological Survey and partners illustrates how climate change is perceived among different generations of indigenous residents in subarctic Alaska. While all subjects agreed climate change is occurring, the older participants observed more overall changes than the younger demographic.

An American pika collects grass and flowers to stockpile its winter food supplies.
August 25, 2016

American pikas – small herbivores that typically live in rocky slopes, known as talus, across many mountain ranges in the American West – are disappearing from some locations across the West due to climate change, according to a study by the U.S. Geological Survey and some of its partners.
