Tree of Life Revealed for Flowering Plants

AUSTIN, Texas—The evolutionary Tree of Life for flowering plants has been revealed using the largest collection of genomic data of these plants to date, report scientists from The University of Texas at Austin and University of Florida. The scientists, publishing two papers in Proceedings of the National Academy of Sciences this week online, found...

Marine Scientists Funded to Study 'Dead Zone'

PORT ARANSAS, Texas— University of Texas at Austin marine scientists have been awarded $781,000 by the National Oceanic and Atmospheric Association (NOAA) to better understand how nutrient pollution from the Mississippi River affects the large area of low oxygen water called the “Dead Zone” in the Gulf of Mexico, and consequently its impact on comm...

Low Oxygen in Coastal Waters Impairs Fish Reproduction

Low oxygen levels in coastal waters interfere with fish reproduction by disrupting the fishes’ hormones, marine scientist Peter Thomas has found.

Global Warming Increases Species Extinctions Worldwide, University of Texas at Austin Researcher Finds

AUSTIN, Texas—Global warming has already caused extinctions in the most sensitive habitats and will continue to cause more species to go extinct over the next 50 to 100 years, confirms the most comprehensive study since 2003 on the effects of climate change on wild species worldwide by a University of Texas at Austin biologist. Dr. Camille Parmesa...

Global warming's impact on U.S. plants, animals determined from review of dozens of studies

AUSTIN, Texas—Global warming has forced U.S. plants and animals to change their behavior in recent decades in ways that can be harmful, according to a new report prepared for the Pew Center on Global Climate Change. The Pew Center review of more than 40 studies is co-authored by Camille Parmesan, integrative biologist at The University of Texas at...

Strongest evidence of global warming provided in new research study

AUSTIN, Texas—A biologist at The University of Texas at Austin has teamed up with an economist to provide the strongest statistical evidence yet that global warming is affecting the natural world. Even when the pair considered habitat destruction or other possible underlying causes for behavior changes in plants, animals and other wildlife, the ana...

UT Austin researcher presents hot new evidence of global warming

AUSTIN, Texas—Ecologists from around the world are finding provocative signs that global warming already may be altering the Earth's flora and fauna. And they worry that next century, when the climate is expected to change more abruptly than it has in at least 10,000 years, plants and animals will be pushed to the limit. If the Earth heats up, wil...
