Bedrock depth influences spatial patterns of summer baseflow, temperature and flow disconnection for mountainous headwater streams

In mountain headwater streams, the quality and resilience of summer cold-water habitat is generally regulated by stream discharge, longitudinal stream channel connectivity and groundwater exchange. These critical hydrologic processes are thought to be influenced by the stream corridor bedrock contact depth (sediment thickness), a parameter often inferred from sparse hillslope borehole information,

A comprehensive assessment of mangrove species and carbon stock on Pohnpei, Micronesia

Mangrove forests are the most important ecosystems on Pohnpei Island, Federated States of Micronesia, as the island communities of the central Pacific rely on the forests for many essential services including protection from sea-level rise that is occurring at a greater pace than the global average. As part of a multi-component assessment to evaluate vulnerabilities of mangrove forests on Pohnpei,

Sediment and nutrient retention on a reconnected floodplain of an Upper Mississippi River tributary, 2013–2018

The connection of rivers with their floodplains has been greatly reduced in agricultural drainage basins, especially in the Upper Mississippi River Basin. The restriction of the Mississippi River from its floodplain has reduced the sediment trapping and nutrient deposition capabilities of the floodplain, exacerbating water quality problems in the river and in downstream waterbodies. A small part o

Mapping Avian Habitat for the Gulf Coast Joint Venture

The Gulf Coast Joint Venture (GCJV) was established in 1988 as a result of the North American Waterfowl Management Plan, which espouses the restoration of continental waterfowl populations through conservation partnerships in priority habitat regions. Since that time GCJV partners have expanded their mission and purpose to include the provision of habitat to support other priority bird species...

CarpDAT Invasive Carp Data Catalog

Four types of invasive carp fish species are currently found in the United States: black, grass, silver, and bighead carps. These species are fast growing, prolific feeders that out-compete native fish species and drastically alter the natural ecosystems they invade.
