Birds that are related, such as Darwin’s finches, but that vary in beak size and behavior specially evolved to their habitat are examples of a process called speciation. It has long been thought that dramatic changes in a landscape like the formation of the Andes Mountain range or the Amazon River is the main… Read More

It’s dark, it’s cold, it’s largely cut off from the outside world, but the lake water under a half-mile of ice in Antarctica is teeming with microbial life. That discovery is the focus of an article in the most recent Nature magazine published Thursday.
LSU’s Brent Christner and Colleagues Document the Existence of Microbial Life Below the Surface of the West Antarctic Ice Sheet in Nature Publication In a finding that has implications for life in other extreme environments, both on Earth and planets elsewhere in the solar system, LSU Associate Professor of Biological Sciences Brent Christner and fellow… Read More

A decadeslong fight over cleaning up one of the nation’s most contaminated riverbeds has posed a difficult question: how to safely remove enough toxic material from New Jersey’s Passaic River to fill two MetLife Stadiums.
Sarcopterygii, or the lobe-finned fishes, includes the coelacanths, lungfishes, fishes involved in the transition to land, and all tetrapods (mammals, amphibians, and reptiles [the birds, turtles, crocodiles, and squamates]). The lobe-finned fishes are Devonian in age and the sister group to Actinopterygii, or ray-finned fishes. Actinopterygii and Sarcopterygii are nearly of equal size (c. 30,000 spp. each). Actinopterygii… Read More
“We still are seeing sick fish, but the incidence of gaping sores has gone down,” Louisiana State University oceanographer Jim Cowan said last week. “We are seeing a high number of fish that have discolored areas on the body … where the scales easily slough off when the fish are handled. We have continued to… Read More
When the Deepwater Horizon disaster leaked an estimated 4.9 million barrels of oil into the Gulf of Mexico, many researchers feared that coastal ecosystems would never be the same. In May 2010, as part of the Gulf of Mexico Research Initiative, or GoMRI, BP committed $500 million over a 10-year period to create a broad… Read More
