Biology and Ecosystems
Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake and Water and information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted. For more information, please see www.doi.gov/shutdown
The Stockton, CA office of the US Fish and Wildlife (USFWS) is leading an intensive effort among Department of Interior (DOI) agencies to develop a first-of-its-kind statistical life-history model for the threatened species delta smelt in the San Francisco Estuary.
The coral microbial ecology group has an active research program identifying and characterizing the microbial associates of both tropical and cold-water (deep-sea) corals and their surrounding habitat. Current projects focus on coral disease dynamics, bacterial diversity, and using metagenomics to elucidate the functional roles of coral microbes.
This project uses amplicon sequencing, functional microarrays, and metagenomics to examine the microbiomes of several deep-sea coral species, with priority given to species that are also of interest to the population genetics group: Desmophyllum dianthus, Paragorgia arborea, Lophelia pertusa, and Primnoa resedaeformis.
The Ecology Section examines how environmental variability, human activities and infrastructure influence food web interactions and species performance in freshwater and marine ecosystems. We have extensive experience in quantifying aquatic food web processes as they relate to growth, survival and production of key species of interest, especially resident and anadromous salmonids.
Sturgeons appear in the fossil record as early as the Triassic, 200 million years ago. Although most populations could once tolerate harvesting pressures, most populations have collapsed and nearly all of the 28 species alive today are listed as threatened or endangered. In New England, dams and water regulation challenge population recoveries of the two resident species, the shortnose and...
Providing information on the implementation of agricultural practices in the Chesapeake Bay watershed
The U.S. Department of Agriculture (USDA) provides cost-share funding and technical assistance to support the implementation of agricultural conservation practices on farms throughout the Chesapeake Bay watershed. Farmer participation in USDA conservation programs is voluntary and the implementation data are privacy protected.
Droughts of the future will be hotter, longer-lasting, and larger than droughts of the past.
Drought can lead to increases in wildfire and insect outbreaks, local species extinctions, forest diebacks, and altered rates of carbon, nutrient, and water cycling – all of which can have real consequences for ecosystems and human communities alike.
The endeavor to ensure a viable population of the threatened wolverine to the mountains of the requires the characterization of suitable habitat.
Virtual reality (VR) provides exciting opportunities for environmental education and research. We invite your participation in a new program to engage students, anglers, and citizen scientists in fish ecology and climate change research using new VR methods. Participants will learn about fish ecology first-hand by exploring streams in VR and will be members of a research team lead by US...
Brine Contamination to Plains and Potholes Environments from Energy Development in the Williston Basin
The focus of our research is the ecological analysis of Pacific Northwest fishes through age and growth structures such as: scales, fin rays and otoliths (small calcium carbonate deposits beneath the brain used in hearing and balance that grow in proportion to the overall growth of the fish). These structures are utilized as research tools for understanding life histories and habitat...
The Mountains Recreation and Conservation Authority (MRCA) is considering plans for developing a new park at the confluence of the Los Angeles River and the Arroyo Seco. These plans include removing channel lining and creating a temporary lake using an inflatable rubber dam. Before implementing the plan, a wide array of scientific and engineering issues must be addressed. The U.S. Geological...
