About 80 million years ago, a group of bees began exhibiting social behavior, which includes raising young together, sharing food resources and defending their colony. Today, their descendants—honey bees, stingless bees and bumble bees—carry stowaways from their ancient ancestors: five species of gut bacteria that have evolved along with the host bees.
Researchers from The University of Texas at Austin have found that honeybees treated with a common antibiotic were half as likely to survive the week after treatment compared with a group of untreated bees, a finding that may have health implications for bees and people alike.
Biologist Mike Ryan, a professor in the College of Natural Sciences at The University of Texas at Austin, has been chosen to receive the 2017 Distinguished Animal Behaviorist Award from the Animal Behavior Society. Considered the Society´s most prestigious award, it "recognizes an outstanding career in animal behavior."
The Ecological Society of America (ESA) announced this week that a University of Texas at Austin professor of integrative biology is one of 27 people in its new class of Fellows.
An assistant professor reflects on a life's work inspired by pollinators and plants.
Scientists at The University of Texas at Austin have observed for the first time that separate populations of the same species — in this case, coral — can diverge in their capacity to regulate genes when adapting to their local environment. The research, published today in Nature Ecology and Evolution, reveals a new way for populations to adapt that may help predict how they will fare under climate change.
A new hunting ground for medically important compounds may be the genome of a stressed-out, poisonous evergreen shrub. Rhazya stricta is a relative of a plant currently mined for chemotherapies and holds promise for future cancer therapies, according to scientists at The University of Texas at Austin, King Abdulaziz University (KAU) in Saudi Arabia and two institutions in Canada, University of Ottawa and Université de Montréal.
Like many predators, the fringe-lipped bat primarily uses its hearing to find its prey, but with human-generated noise on the rise, scientists are examining how bats and other animals might adapt to find their next meal. According to a new study, when noise masks the mating calls of the bat's prey, túngara frogs, the bat shifts to another sensory mode—echolocation.
Faculty members in the College of Natural Sciences are leading new Pop-Up Institutes as part of a new interdisciplinary research initiative at The University of Texas at Austin. Three Pop-Up Institutes were announced this week, with two originating in Natural Sciences. These research efforts will assemble fresh collaborations to address the influence of individual variation on the health and fitness of populations and the impact of discrimination on health outcomes.
Some of the bacteria in our guts were passed down over millions of years, since before we were human, suggesting that evolution plays a larger role than previously known in people's intestinal-microbe makeup, according to a new study in the journal Science.
Last week Robert Deans, a University of Texas at Austin graduate student in ecology, evolution and behavior, discovered an extremely rare orchid in an unexpected place—at an urban biological field station in the heart of Austin, Texas.
An extremely rare eyeless catfish species previously known to exist only in Mexico has been discovered in a National Recreation Area in Texas.
According to a new study by The University of Texas at Austin, increasing the diversity of pollinator species, including bees, flies and butterflies, can dramatically increase cotton production. The researchers estimate that in South Texas, the region they studied, increasing the diversity of pollinators could boost cotton production by up to 18 percent, yielding an increase in annual revenue of more than $1.1 million.
Evolutionary biologist James Bull of The University of Texas at Austin has been elected to the National Academy of Sciences (NAS).
