Fish Marks 36th Non-Native Marine Fish Species Found in State

As coastal development along the Gulf Coast continues to expand, tidal saline wetlands could have difficulty adjusting to rising sea levels.

Genetics and tracking helps USGS researchers learn where the invasive fish are now – and where they may go next.

Researchers from the U.S. Geological Survey and Louisiana State University have identified a new genus and species of cavefish from Mexico, the Oaxaca Cave Sleeper, which is the first cave-adapted sleeper goby to be found in the Western Hemisphere.

A special edition of the journal Ecological Modelling has been dedicated to Donald DeAngelis, U.S. Geological Survey Research Ecologist, in honor of his 70th birthday. A a prominent contributor to the journal, DeAngelis has played a decisive role in the progression of ecological and mathematical modeling, specifically related to individual-based approaches.

Our transitional site includes the new usgs.gov and more than 180 top-level pages (Mission Areas, Programs, Regions, our three new Science Center websites, Products, Connect, About, etc.). We will migrate more USGS websites into this new experience; check back often to see our progress.

Snake fungal disease, or SFD, a disease causing high mortality rates in some species of snakes, has been found in Louisiana for the first time, according to a new study by U.S. Geological Survey scientists. SFD now has been confirmed in at least 16 states in the Eastern and Midwestern United States.

Boaters, swimmers or other members of the public who see Lionfish, Asian carp, Zebra mussels or any other invasive or non-native plant or animal species have two options to report sightings.

It may be hard to believe the legend that sailors long-at-sea once believed manatees to be mermaids. The manatee nickname the “Sea Cow” – named so for their affinity for grazing on vegetation and their slow, ambling way – just makes more sense. But a new U.S. Geological Survey video reveals that while they may be cow-like, they also have more than a bit of magical mermaid to them.

Researchers have found clear evidence that biological communities rich in species are substantially healthier and more productive than those depleted of species.

Alligators and the Everglades go hand-in-hand, and as water conditions change in the greater Everglades ecosystem, gators are one of the key species that could be affected.
