When She's Turned On, Some Of Her Genes Turn Off

AUSTIN, Texas—When a female is attracted to a male, entire suites of genes in her brain turn on and off, show biologists from The University of Texas at Austin studying swordtail fish. Molly Cummings and Hans Hofmann found that some genes were turned on when females found a male attractive, but a larger number of genes were turned off. “When fema...

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...
