Scientists Find New Clues to Explain Amazonian Biodiversity

AUSTIN, Texas--Ice age climate change and ancient flooding—but not barriers created by rivers—may have promoted the evolution of new insect species in the Amazon region of South America, a new study suggests. The Amazon basin is home to the richest diversity of life on earth, yet the reasons why this came to be are not well understood. A team of ...

Coral Health And Bacterial Communities

PORT ARANSAS, Texas—Bacterial communities endemic to healthy corals could change depending on the amount and type of natural and man-made dissolved organic matter in seawater, report researchers from The University of Texas at Austin Marine Science Institute and Mote Marine Laboratory in Sarasota, Florida. Healthy corals naturally exude a surround...

Monitoring Texas Bays For Dangerous Algal Blooms

PORT ARANSAS, Texas—A new electronic sentinel is on the lookout for dangerous algal blooms in Texas bays. The new instrument, called the Imaging FlowCytobot, automatically takes images of and classifies species of phytoplankton in real-time. It heralds the development of a warning system for the presence of harmful algae, like those that cause red...

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 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...
