Florida manatee

Past Water Patterns Drive Present Wading Bird Numbers

Wading bird numbers in the Florida Everglades are driven by water patterns that play out over multiple years according to a new study by the U.S. Geological Survey and Florida Atlantic University. Previously, existing water conditions were seen as the primary driving factor affecting numbers of birds, but this research shows that the preceding years’ water conditions and availability are equally important. arrow iconLink to USGS Press Release




Florida manatee

Long-term Prognosis for Florida Manatees Improves

The risk of extinction for the endangered Florida manatee appears to be lower, according to a new U.S. Geological Survey led study.

Based on the data available in 2012, the long-term probability of the species surviving has increased compared to a 2007 analysis, as a result of higher aerial survey estimates of population size, improved methods of tracking survival rates, and better estimates of the availability of warm-water refuges.

USGS scientists, working with colleagues from several other agencies and universities, used the manatee Core Biological Model to analyze the long-term viability of the manatee population in Florida, and to evaluate the threats it faces. A similar analysis completed in 2007 was used by the U.S. Fish and Wildlife Service as part of its 5-year Review of the status of manatees. arrow iconLink to Press Release

Many Dry Tortugas Loggerheads Actually Bahamas Residents

Many loggerhead sea turtles that nest in Dry Tortugas National Park head to rich feeding sites in the Bahamas after nesting, a discovery that may help those working to protect this threatened species.

Researchers from the U.S. Geological Survey used satellites to track the population of loggerheads that nest in the Dry Tortugas – the smallest subpopulation of loggerheads in the northwest Atlantic – and found the turtles actually spend a considerable portion of their lives in the Bahamas, returning to the Dry Tortugas to nest every two-to-five years. They then spend three-to-four months nesting in the Dry Tortugas before returning to the Bahamas. arrow iconUSGS News Release

Cerianthid anemones, also known as tube anemones, are not true anemones. They live in a tube they build using mucus, surrounding mud, and thread-like structures produced by its cells. Credit: NOAA-OER/BOEM/USGS

Pathways to the Abyss

A new video by the Bureau of Ocean Energy Management includes highlights of some of the contributions of U.S. Geological Survey scientists during a five-year study of two deep mid-Atlantic canyons located 100 miles offshore of Virginia and Maryland.

USGS researchers collaborated with academic and private organizations and institutions, BOEM and the National Oceanic and Atmospheric Administration to conduct ecosystem-based science to support the responsible exploration and development of the nation’s resources. This interdisciplinary, collaborative effort represents one of the most comprehensive studies of deep-sea canyons. arrow iconUSGS Science Features - Top Story
