Most Extensive Genetic Resource For Reef-Building Coral Created

AUSTIN, Texas — A nearly complete collection of genes for a species of reef-building coral has been assembled by a team led by biologists from The University of Texas at Austin. The scientists will use the genetic data to understand natural variations in corals from around the world and how they respond, at the genetic level, to rising water tempe...

Sex Isn't Everything

The ants, Mycocepurus smithii, amongst their fungus garden. Photo: Alex Wild. In the end, sex might not be everything. At least, that’s the story for a fungus-farming ant that seems to be doing just fine without it. In fact, they’ve done away with males entirely, a “first ever” for the ant world. Most social insects—the wasps, ants and bees—are...The ants, Mycocepurus smithii, amongst their fungus garden. Photo: Alex Wild.

Live-in Domestics: Mites as Maids

Mites not only inhabit the dust bunnies under the bed, they also occupy the nests of tropical sweat bees where they keep fungi in check. Bees and their young are healthier when mites live-in, report researchers from the Smithsonian Tropical Research Institute (STRI) in Panama and The University of Texas at Austin. Mutually beneficial cleaning relat...Stingless bee

Cool Class: Bug Boot Camp

Katy Kenny decided to take John Abbott’s Field Entomology class in the summer of 2007 for two reasons. One was that she’d heard from friends that the three week “mini-mester” course, which Abbott teaches just after the spring semester ends, was interesting. The other was that she wanted to overcome her fear of bugs. “It helped,” says Kenny, a biol...katy kenny

Dry Times

Images from a thermal camera show that the German Arabidopsis plants transpire less and are hotter (bottom three). This contrasts with the German plants that have a key section of chromosome from Cape Verdean plants. They transpire more and are much cooler (top three). Any farmer or gardener worth their salt understands the power of water to giv...Images from a thermal camera show that the German Arabidopsis plants transpire less and are hotter (bottom three).

Troubled Waters: A rare desert spring ecosystem considered one of Mexico's 13 natural wonders is threatened

Sprawling across a cactus-studded valley in México's Chihuahuan Desert is a place like no other on the planet.

The Endangered Aquatic Box Turtle

The Coahuilan aquatic box turtle is found in a unique valley in Mexico called Cuatrociénegas and no where else on the planet. It's the only aquatic box turtle in the world. Scientists estimate that only about 2000 exist in the wild and their habitat is quickly shrinking due to over use of water in agriculture, climate change and invasive species. U...

Cactus Odyssey

In January of this year, biologist James Mauseth published the fourth edition of his textbook, Botany: An Introduction to Plant Biology. It draws on his more than three decades of research and teaching in the field of plant biology, and in particular on the insights he’s gleaned from the study of cacti. I sat down with Mauseth, a professor of inte...jdm
Amazonian Amphibian Diversity Traced to Andes

Amazonian Amphibian Diversity Traced to Andes

AUSTIN, Texas — Colorful poison frogs in the Amazon owe their great diversity to ancestors that leapt into the region from the Andes Mountains several times during the last 10 million years, a new study from The University of Texas at Austin suggests. This is the first study to show that the Andes have been a major source of diversity for the Amaz...

The Lamprey Factor

Biologist Jennifer Morgan studies the regeneration of neural function in lampreys after spinal cord injury. Her work, which is funded by grants from the Paralyzed Veterans of America and the Morton Cure Paralysis Fund, may have implications for treatment of spinal cord injuries in humans.

Oldest Living Lineage of Ants Discovered in the Amazon

AUSTIN, Texas—A new species of blind, subterranean, predatory ant discovered in the Amazon rainforest by University of Texas at Austin evolutionary biologist Christian Rabeling is likely a descendant of the very first ants to evolve. The new ant is named Martialis heureka, which translates roughly to “ant from Mars,” because the ant has a combinat...

Genes of Attraction

This array shows 306 genes in female swordtails turning on (red), turning off (green) or not changing (black). When females were with attractive males, many of their genes turned off (first column, green). The same genes were turned on when females were with other females (second column, red). The third and fourth columns show gene activity when fe...This array shows 306 genes in female swordtails turning on (red), turning off (green) or not changing (black).

The third and forth columns show gene activity when females were swimming with unattractive males or alone, respectively.
