Department of Biology
The Department of Biology offers exceptional opportunities to learn, work, and collaborate across levels of biological organization and styles of research. Faculty research interests span the complete spectrum of biological phenomena and disciplines, from biochemistry to global environmental change. This breadth of research interests has led to development of three focused, yet overlapping, graduate training programs: Molecular, Cellular, and Evolutionary Biology (MCEB), Ecology Evolution and Organismal Biology (EEOB), and Microbial Biology.
May 26, 2016 - Sylvia Torti, Sylvia Torti has won the third annual Nicholas Schaffner Award for Music in Literature, and her novel Cages will be published by Schaffner Press in 2017. "Cages reminds me of the novels of Richard Powers in its mix of real science and real people grappling with issues like the ethics of experimentation," said publisher Timothy Schaffner. "The novel brings up fascinating and important questions about the source of memory, and whether it can be located in the human brain." Sylvia's first novel, The Scorpion's Tail won the 2005 Miguel Mármol Prize.

Why Vultures Matter
May 5, 2016 - Vultures. Cartoon characters in parched deserts often wish them to disappear, since circling vultures are a stereotypical harbinger of death. But, joking aside, vultures in some parts of the world are in danger of disappearing. And according to a new report from University of Utah biologists, Evan Buechley and Çağan Şekercioğlu, such a loss would have serious consequences for ecosystems and human populations alike.The primary threat to vultures, according to the report published today in Biological Conservation, is the presence of toxins in the carrion they consume. Populations of most vulture species around the world are now either declining or on the brink of extinction. See Full Story...

Which trees risk death
April 18, 2016 - Drought left 225 million trees dead in the U.S. Southwest in 2002. Nine years later, it killed 300 million trees in Texas. This past year, 12 million trees died in California. Throughout the world, large numbers of trees are dying in extreme heat and drought. Such mass die-offs can have critical consequences for the future of forests and Earth's climate. On Earth Week, scientists are trying to understand how a warming climate could affect how often tree mortality events occur -- and how severe they could become. A University of Utah biologist may be able to help. William Anderegg and his colleagues looked for patterns in previous studies of tree mortality and found some common traits that characterized which species lived and which died during drought. The results, published today in the journal Proceedings of the National Academy of Sciences (PNAS), can help chart the future of forests. See Full Story... More Coverage...

Broad diet helps birds in fast-changing world
April 8, 2016 - In 2000, biology professor Çağan Şekercioğlu began building a global database of bird traits that now contains 1.4 million entries covering all known bird species. The database is a rich and versatile resource for biologists. The latest study to draw on Şekercioğlu's database, “Omnivory in birds is a macroevolutionary sink”, was published Thursday in Nature Communications and examines the role of how birds’ diets affect how new species arise and how others fall to extinction. In a stable environment, being a jack-of-all foods is risky. Omnivorous birds lose out to birds with specialized diets, hence omnivory is generally associated with higher extinction risk and fewer new species. In our human-affected world with disappearing habitats and a changing climate, however, having a broad diet is an advantage and helps omnivorous birds survive while specialists face extinction. Şekercioğlu, a co-author on the paper, is available to discuss the work’s results and implications. See Full Story...
New species of Ethiopian Viper
March 28, 2016 - While driving through Ethiopia’s Bale Mountains National Park in 2013, graduate student Evan Buechley of the University of Utah, and his colleagues, spotted a black-colored snake with pale-yellowish markings. The driver stopped the vehicle, and the team photographed the one-meter long snake. To date, these are the only known photographs of what scientists say could be a new species of venomous Bitis viper. Now, in a study published in Zootaxa, researchers have confirmed that the snake is most likely a novel species of Bitis viper. See Full Story...
Pigeon Foot feather Genes identified
University of Utah scientists identified two genes that make some pigeon breeds develop feathered feet known as muffs, while others have scaled feet. The same or similar genes might explain scaled feet in chickens and other birds, and provide insight into how some dinosaurs got feathers before they evolved into birds. The study found that in pigeons with feathers on their hindlimbs or feet, a hindlimb-development gene named Pitx1 is less active than normal, while a forelimb-development gene named Tbx5 is active in the feet, where it normally is not. In other words, “pigeons’ fancy feathered feet are partially wings,” says biologist Dr. Michael Shapiro, senior author of the study published today by the journal eLife. See Full Story...
Nurturing nature’s habitat on campus
Feb. 9, 2016 - We may have forgotten that the University of Utah campus is an ecosystem, an environment for student learning to take place and a habitat for other species to live and thrive. A small group of students are paying attention to the latter issue by working to increase the kestrel populations on campus and learn more about the species’ natural history. Colter Dye, a biology student at the U, is at the forefront of this initiative. He says the idea hatched after taking a biology class last spring. “I hope that the University of Utah will serve as a model for other colleges, on how to integrate campus wildlife research and habitat preservation into grounds activities,” says Amy Sibul of the Biology Department's Community Engaged Learning. If you’re interested in getting involved, contact Sibul or attend the next Wildlife Society meeting. The Wildlife Society meets on the first and third Thursday of each month at 3:30 in ASB 304 and is open to students, staff, and faculty from all departments. See Full Story...

Dead or Alive-infrared cameras and beehives
Feb. 3, 2016 - The U of U Dept. of Biology, headed by Amy Sibul, using a grant from the Sustainable Campus Initiative Fund, has loaned the Utah Dept. of Agriculture and Food an infrared camera that allows inspectors to “see” into hives without opening the hives, which may expose living bees to freezing temperatures. The FLIR camera detects heat signatures in the hive. If the hive has a strong heat signature they will leave it alone. The infrared camera winter beehive health inspection program is among the first of its kind nationally and one of many free services available to registered beekeepers to help them better manage their colonies. "Some people imagine either that (bees) freeze and then thaw out in the winter or that they hibernate, but the bees are actually awake and alive through the winter and they stay in a cluster," said bee inspector Stephen Stanko in a Utah Agriculture video.

What a moth's nose knows
Jan. 27, 2016 - Moths sniff out others of their own species using specific pheromone blends. So if you transplant an antenna – the nose, essentially – from one species to another, which blend of pheromones does the moth respond to? The donor species’, or the recipients’? The answer is neither. Moths with transplanted antennae responded instead to a similar yet novel pheromone blend not naturally produced by either species, according to University of Utah research published online Jan. 27 in PLOS ONE. The result, says biology professor Neil Vickers, reveals how the brain depends on the senses to construct an impression of reality, and how changing the sensory hardware can cause the moths’ brains to be fooled.

Poison Warmed over
Jan. 21, 2016 - UofU Dearing Lab experiments found that when temperatures get warmer, woodrats suffer a reduced ability to live on their normal diet of toxic creosote – suggesting that global warming may hurt plant-eating animals. “This study adds to our understanding of how climate change may affect mammals, in that their ability to consume dietary toxins is impaired by warmer temperatures,” says biologist Denise Dearing , senior author of the research published online Jan. 13 in the British journal Proceedings of the Royal Society B. “This phenomenon will result in animals changing their diets and reducing the amount of plant material they eat, relocating to cooler habitats or going extinct in local areas,” says Dearing, a distinguished professor and chair of biology at the University of Utah, and Patrice Kurnath, a doctoral student in biology.
