Sex, lice and videotape

June 10, 2019 - A few years ago, Scott Villa of Emory University had a problem. Then a graduate student in the Clayton/Bush lab at the University of Utah, he was stumped with an issue never addressed in school: How does one film lice having sex? Villa and University of Utah biologists had demonstrated real-time adaptation in their lab that triggered reproductive isolation in just four years, mimicking millions of years of evolution. They began with a single population of parasitic feather lice, split the population in two and transferred them onto different-sized hosts—pigeons with small feathers, and pigeons with large feathers. The pigeons preened at the lice and populations adapted quickly by evolving differences in body size. See PNAS Article... See UNews Article...

Latest issue of 'our DNA'

June 4, 2019 - OUR DNA is a dynamic 360-degree snapshot of both the depth and breadth of the people, the research and the classroom instruction that make up one of the University of Utah's most celebrated academic units. Our first academic year as the School of Biological Sciences was a smashing success! Look here for new research in genetics (Nitin Phadnis Lab) | Alumni profiles (The Gandhi Siblings and Jeanne Novak of CBR fame) | Science Outreach (The Landscape Lab, which just broke ground here in SLC) and more.  Also…a special feature on retiring faculty member, cell biologist and former undergraduate advisor Dave Gard (these days you’ll find him angling on the Green River). Guess who’s an alumni of U Biology? Look for updates on LDS Church President Russell M. Nelson (BS’45),  founder of Clear Choice Dental Implants Ole Jensen (BS’72), Harvard PhD Daina Graybosch (BS’01) now at SVB Leerink in NYC, and Mixed Martial Arts bantamweight fighter the formidable Taylor Thompson (BS’14).See Current Issue of OUR DNA ...

Insect Endosymbiont from the Cradle to the Grave

June 3, 2019 - Host-beneficial endosymbioses, which are formed when a microorganism takes up residence inside another cell and provides a fitness advantage to the host, have had a dramatic influence on the evolution of life. These intimate relationships have yielded the mitochondrion and the plastid (chloroplast) — the ancient organelles that in part define eukaryotic life — along with many more recent associations involving a wide variety of hosts and microbial partners. These relationships are often envisioned as stable associations that appear cooperative and persist for extremely long periods of time. But recent evidence suggests that this stable state is often born from turbulent and conflicting origins. . .Read the article co-authored by U Biology professor Dr. Colin Dale.

A forest "glow" reveals awakening

May 29, 2019 - Winters in the northern hemisphere are brutal. The harsh conditions drive some species to hibernate; bears reduce their metabolic state to conserve energy until spring. Forests also endure winter by conserving energy; they shut down photosynthesis, the process by which a green pigment called chlorophyll captures sunlight and carbon dioxide (CO2) to produce the chemical energy that fuels the plants. “You and I can get sunburned. Too much ultraviolet radiation will damage our cells. Some people can protect themselves— their skin produces more of the pigment melanin to adjust to high-light environments,” said David Bowling of the Bowling Lab, biology professor at the University of Utah and coauthor of the study. “Plants have a different, but similar process.” See UNews story...

Faculty teaching excellence Award

May 1, 2019 - Congratulations to Dr. David Temme for being awarded the 2018-2019 Faculty Teaching Award for Excellence in General Education. The committee was most impressed by the unique approach Dr. Temme takes to teaching biology, the depth of his commitment to student learning and the years of dedicated service to high quality biology instruction in General Education. “It is commonplace to hear them [students] say that Dave is one of the most outstanding teachers they have experienced. They always state that he can take a vast field of knowledge and make it extremely conceptual and clear. He gives them tools and approaches to synthesize the knowledge, rather than just dispensing the knowledge itself. ” 

Are Coffee Farms for the Birds?

April 29, 2019 - Over 11 field seasons, between 1999 and 2010, ornithologist Çağan Şekercioğlu of the Şekercioğlu Lab trekked through the forests and coffee farms of Costa Rica to study how tropical birds were faring in a changing agricultural landscape. Through painstaking banding of individual birds, ?ekercio?lu asked whether the expansion of coffee plantations is reducing tropical bird biodiversity. The answer, published today in Proceedings of the National Academy of Sciencesis no. And yes. Sun coffee plantations are able to host a surprising number of bird species, even more if the plantation has some tree cover. But the plantations are not enough to maintain bird biodiversity.

Speaking for the raptors

April 22, 2019 - Birds of prey such as owls, eagles, falcons and vultures are soaring and elegant predators. But many raptors worldwide have flown under the scientific radar and are all but invisible: Ten species of raptors, out of 557 total, comprise one-third of all raptor research, and one-fifth of all species have never been studied in a scientific publication. That’s the conclusion of a recent paper in Diversity and Distributions by University of Utah researchers and their collaborators. The most understudied raptor species tend to be those with small geographic ranges and those in less developed regions. Unfortunately, those same factors contribute to a species’ extinction risk.

Putting Science in Science communication

Mar. 27, 2019 — Bring science to people where they are. That’s the driving philosophy that propels U biology professor Nalini Nadkarni to stretch the possibilities of science communication and bring the beauty of science to people and places that others have overlooked. Building public trust in science is about more than just providing information and improving science literacy, she says. It’s about building relationships between scientists and communities that are founded on shared values. In two recent studies, one published today in BioScience and another published in 2018 in Science CommunicationNadkarni and her colleagues present evidence-based conclusions about the effectiveness of science engagement in two programs: “Our goal is to help people realize that all citizens are interested in, capable of understanding and full of wonder at science, if it is presented in places and ways that are accessible to them,” Nadkarni says.

Fighting Leaf and Mandible

March 14, 2019 - Researchers have been baffled by tropical rainforest diversity for over a century; 650 different tree species can exist in an area covering two football fields, yet similar species never grow next to each other. It seems like it’s good to be different than your neighbors, but why?  To grow in a tropical rainforest is to engage in constant warfare. Related trees share the same pests and diseases—if one gets it, the infestation can spread. Scientists have asked, “What is the primary driver in tropical forest diversity–competition for resources, or herbivore pests?”  For the first time, University of Utah biologists in the Coley/Kursar Lab compared the two mechanisms in a single study. “Despite state-of-the-art laboratory facilities, there’s no substitute for spending months and months in the rainforest,” said Dr. Phyllis Coley, Distinguished Professor of Biology at the University of Utah, research affiliate at the Smithsonian Tropical Research Institute and co-author of the study. “It took us several years to collect data, and samples of leaves and herbivores. It’s hot, humid and buggy, but attempting to understand the diversity of species is a biologist’s dream.”See UNews story... See Science Article...

Cells under stress

March 14, 2019 - A new article has been published in the Journal of Cell Biology by Dr. Julie Hollien and members in her lab. "Cells respond to stress in the ER by initiating the widely conserved unfolded protein response. Activation of the ER transmembrane nuclease IRE1 leads to the degradation of specific mRNAs, but how this pathway affects the ability of cells to recover from stress is not known. Here, we show that degradation of the mRNA encoding biogenesis of lysosome-related organelles 1 subunit 1 (Blos1) leads to the repositioning of late endosomes (LEs)/lysosomes to the microtubule-organizing center in response to stress in mouse cells".

U Biologists trigger adaptive radiation

March 5, 2019 - University of Utah biologists experimentally triggered adaptive radiation; they used host-specific parasites isolated on individual pigeon "islands." Lead authors Sarah Bush and former U PostDoc Scott Villa showed that descendants of a single population of feather lice adapted rapidly in response to preening, the pigeons' main defense. "People have been trying to bridge micro- and macro- evolution for a long time," said Dale Clayton, professor in biology at the U and co-author of the paper. "This study actually does it. That's a big deal." Co-authors include U biologists Michael Shapiro and Juan Altuna. Story in AAAS EurekAlert... See full article... Story in The Atlantic... Commentary in Journal of Exp Biology...
