Crocodilian Evolution

UD’s Schmidt studies genome of crocodile family in evolution research

University of Delaware scientist Carl Schmidt is working to identify genes in crocodiles, alligators and gharials as he searches for links between the creatures that could give clues as to how they evolved over the years in relation to one another.

Schmidt’s effort is part of a National Science Foundation-funded project being conducted by a team of researchers assembled by David Ray, an evolutionary biologist at Mississippi State University. (more…)

Interior Releases First-of-its-Kind Regional Study as Part of National Assessment of Carbon Storage in U.S. Ecosystems

*Report evaluates amount of carbon absorbed by wetlands, grasslands and forests in the Great Plains region*

WASHINGTON, D.C. — The Department of the Interior today released the first in a series of regional studies measuring the amount of carbon stored in U.S. ecosystems. Published by Interior’s U.S. Geological Survey (USGS), the study examines the current and projected future carbon storage in the Great Plains region, as part of a nation-wide assessment.

“This is truly groundbreaking research that, for the first time, takes a landscape-level look at how our lands naturally store carbon and explores how we can encourage this capability in ways that enhance our stewardship of natural resources,” said Deputy Secretary of the Interior David J. Hayes. “Our landscapes are helping us to absorb carbon emissions that would otherwise contribute to atmospheric warming.” (more…)

New Understanding of How Humans and the Environment Interact

*National Science Foundation Grants Awarded for Research on Coupled Natural and Human Systems*

Water quality and environmental health in Botswana; wetlands in a working landscape; the collapse of the ancient Maya and what that has to tell us about society and environmental change today.

These and other projects that address how humans and the environment interact are the focus of $21 million in National Science Foundation (NSF) grants to scientists, engineers and educators across the country to study coupled natural and human systems. (more…)

Fossil Bird Study Describes Ripple Effect of Extinction in Animal Kingdom

GAINESVILLE, Fla. — A University of Florida study demonstrates extinction’s ripple effect through the animal kingdom, including how the demise of large mammals 20,000 years ago led to the disappearance of one species of cowbird.

The study shows the trickle-down effect the loss of large mammals has on other species, and researchers say it is a lesson from the past that should be remembered when making conservation, game and land-use decisions today. (more…)

Many Coastal Wetlands Likely to Disappear this Century

Many coastal wetlands worldwide — including several on the U.S. Atlantic coast — may be more sensitive than previously thought to climate change and sea-level rise projections for the 21st century.

U.S. Geological Survey scientists made this conclusion from an international research modeling effort published on December 1 in the journal Geophysical Research Letters, a publication of the American Geophysical Union. Scientists identified conditions under which coastal wetlands could survive rising sea level. (more…)
