Testing a Small, Portable Remote Passive Acoustic Device to Monitor Wolves

Submitted by atripp on Tue, 12/27/2022 - 09:32

As part of a broader trial of noninvasive methods to research wild wolves (Canis lupus) in the Superior National Forest (SNF), Minnesota, the USGS Wolf and Deer Project (Northern Prairie Wildlife Research Center) explored whether wolves could be remotely monitored using a new, inexpensive (approximately $80 USD in 2019), remotely deployable, passive acoustic recording device.

Water Use for the Delaware River Basin from 1950–2099

Submitted by atripp on Fri, 12/23/2022 - 13:01

The Delaware River Basin is an important water resource for Philadelphia and other cities in the region. It was chosen to demonstrate USGS’s model integration efforts to investigate the relationships among water use, land cover, and climate to assess and forecast the impact of changes in these parameters on the environment and water resources.

Multiscale Spectroscopy of Intertidal Biofilm Quantity, Quality, and Composition

Submitted by tadamson on Tue, 12/20/2022 - 14:05

Microbial biofilm communities, which are comprised of bacteria, diatoms, protozoa, and fungi, inhabit the surface of intertidal mudflats. They play a major role in intertidal food webs and comprise a large proportion of shorebirds’ diets, so understanding biofilm distribution, quantity, and nutritional value is important for shorebird conservation and management.

Evaluating Crop Residue Bands for the Landsat Next Mission

Non-photosynthetic vegetation (NPV) includes the residual material left on a field after crop harvest, such as stalks, stubble, and seeds. Satellite-based detection and mapping of NPV supports better understanding of soil health, adoption of conservation tillage practices, and vegetation dynamics in cropland, pasture, and rangeland settings.

Distribution of Migratory Landbirds around the Gulf of Mexico

Submitted by atripp on Thu, 06/17/2021 - 16:01

Over two-thirds of all land birds and over half of the migratory species in North America move long distances to areas in Mexico, Central and South America, and the Caribbean islands. For birds crossing the Gulf of Mexico, habitats along the northern coast provide the last possible stopover before autumn migrants make a nonstop flight.

Automated Telemetry to Understand Habitat Use and Movement Ecology

Submitted by atripp on Thu, 06/17/2021 - 15:52

Telemetry has advanced understanding of wildlife biology in lockstep with advances in technology. Recent development of automated radio tracking systems can provide precise information on habitat use at small-scale and large-scale movements across continents by continually monitoring for tag frequencies.
