Like all living things, plants have to respond and adapt to various stressors in their environment. But unlike most living things, plants must cope with these issues while being completely immobile.

In the field.

This stalwart resilience fascinated Eleinis Ávila-Lovera in her undergraduate years, an interest that has guided her entire educational journey as a plant ecophysiologist. Drawn to the deserts of the region, she has found her way here as an assistant professor of the School of Biological Sciences

Starting in Venezuela where she was born and raised, Ávila-Lovera was inspired by her grandparents to live her life to its fullest potential. Her grandmother Leonidas Guevera de Lovera taught her to read and write at the age of four. When combined with her grandfather Luis Lovera’s work ethic setting a perfect example, Ávila-Lovera was able to adapt and thrive as efficiently as the plants she would eventually study. Guided by the insightful teaching of her undergraduate mentor Wilmer Tezera, she was quickly drawn to the arid environments of the region. It’s hard enough to weather the world while immobile, exponentially more so in the scorching heat with no water. And yet, countless plants are able to adapt and thrive in these conditions.

“There’s a particular genus called Parkinsonia (palo verde),” Ávila-Lovera explains when asked for an example, “Whose bark is completely green. It’s a drought-deciduous plant, meaning that it loses its leaves during the dry season. In a desert this could lead to zero carbon gain, yet the palo verde is still able to withstand the arid heat, because the green stem helps them continue acquiring carbon despite the lack of leaves.”

Plants such as this are the focus of Ávila-Lovera’s research. Her lab is currently working on two projects: One, led by graduate student Osedipo Adegbeyeni, is comparing the water status regulation between leaves and photosynthetic stems in desert plants. The other, led by postdoctoral researcher Oranys Marin, is studying the link between hydraulic conductivity and stem photosynthesis in desert plants. Ultimately the former project aims to decipher differences in how stems and leaves tolerate drought conditions. The latter explores the potential coordination of traits that allow better performance of plants in drought conditions.

Ávila-Lovera also currently teaches BIOL 5460, Plant Ecology in a Changing World. Taking inspiration from the adaptations she has studied, she wishes to create a classroom environment that provides students all the tools and resources they need to thrive. Being over 3,000 miles from home herself, she’s well versed in the process of learning to flourish in unfamiliar soil. She aspires not just to transmit information, but to provide the basis that allows  students to master and apply their newfound knowledge in turn.

“It’s important to remember that ecology as a science has the same rigorous background as other sciences,” Ávila-Lovera explains. “I do consider myself an environmentalist. I do not eat red meat or poultry and try to reduce my carbon footprint. But ecology itself is a science; we’re testing hypotheses, and it’s critical to approach it with the organization and structure one would expect.”

Having been allowed to thrive by multiple mentors before her, Ávila-Lovera eagerly looks forward to providing a similar mentorship role to her current and future students.

How Harmful is Great Salt Lake Dust? U Scientists Investigate

How Harmful is Great Salt Lake Dust?
U Scientists Investigate


September 17, 2024

As Utah’s Great Salt Lake shrinks, exposing more of its playa, concerns grow about the dust the dry lakebed emits. But scientists lack the data to fully understand what pollutants are present in these airborne sediments.

Researchers from the University of Utah, including atmospheric scientist Kevin Perry and biologist Michael Werner, are attempting to get a handle on this question and the latest findings are concerning.

Sediments in the lake’s exposed playa are potentially more harmful than other major dust sources affecting the Wasatch Front’s air quality, according to a study published online recently in the journal Atmospheric Environment.

“You’re talking about a very large dust source located next to a very large population, and you’ve got elevated levels of manganese, iron, copper and lead. Lead is a concern for developmental reasons,” said senior author Kerry Kelly, a professor of chemical engineering. “Manganese, iron and copper, these are transition metals and are known to be very irritating to your lungs. Once you get irritation, that can lead to this whole inflammatory response. And that’s part of the problem with particulate matter and it’s adverse health effects like asthma.”

Another recent study led by sociology professor Sara Grineski found dust from the lakebed disproportionately affects disadvantaged neighborhoods in Salt Lake County.

In a separate forthcoming study led by U biologist Michael Werner’s lab, another team of researchers characterized levels of toxic metals deposited in submerged lakebed sediments sampled during the lake’s record low-water year of 2021, noting how these levels have changed since the years of Utah’s mining era.

To conduct the published study, Kerry Kelly’s lab, which specializes in air quality, teamed up with researchers in the U’s College of Science. They examined previously collected sediment samples from the Great Salt Lake, comparing them with sediments from other dust sources in the Great Basin, namely Sevier Lake, Fish Springs Lake and West Desert in western Utah and Tule Lake in northeastern California. These places are known to contribute to dust pollution reaching Salt Lake City.

In recent years, co-author Kevin Perry, a professor of atmospheric sciences, has systematically gathered exposed lakebed sediments, logging hundreds of miles on a bike. His prior research has identified “hotspots” on the playa that appear to be enriched with potentially toxic elements.

Wolves and Humans in Rural Turkey

Utah biologists track gray wolves with GPS collars and camera traps as their numbers rebound into populated parts of northeast Turkey.

After 14 years of gathering and analyzing field data, an international research team led by University of Utah biologist Çağan Şekercioğlu has released the first and only study of gray wolf movements and ecology in Turkey. Using GPS collars and camera traps, researchers tracked seasonal variations of wolves’ range sizes in the highlands of Turkey’s rural northeastern corner, where people are widely present during the summer but mostly absent in the winter when the area is completely snowbound. The team was surprised to discover human presence had no effect on wolf movements.

“Even though human activity changes drastically, wolves are not taking advantage of that by increasing their home range size or changing their home range size between the seasons when humans are there and when they’re not there,” said J. David Blount, lead author of the study published this month in the journal Wildlife Biology. “Theoretically they have a lot of different needs during these times that should be fluctuating, especially with the dispersing wolves.”

“Wolves are very adjustable, which leads to many exciting behavioral adaptations,” said Blount, a graduate student in Şekercioğlu’s lab. “However, studies are pretty context-dependent.”

Since the mid-1990s, wolves have been making a comeback following re-introductions in the Yellowstone region, Arizona and, most recently, western Colorado. The wolf situation in eastern Turkey is completely different, according to Şekercioğlu, a professor of biology. While wolves have been a problem for livestock operations, shepherds and ranchers have learned to live with the apex predator with the help of Anatolian sheepdogs, which protect cattle and sheep without harming the wolves.

The study area covered 550 square kilometers surrounding Sarıkamış, a town of 15,500.  Over 14 research seasons, running from mid-May to mid-August, the research team captured 46 wolves and fitted them with GPS collars, which recorded a location every five hours and are designed to fall off after two years. The cameras yielded 26,000 photos of wildlife and countless others that recorded animals other than wildlife.

According to the study, as wolves resettle areas near towns, understanding how wolves adjust their temporal and spatial patterns in human-dominated landscapes can contribute to their conservation. An ornithologist who studies tropical songbirds, Şekercioğlu began eying wolves when he moved from Stanford University in 2010 and used startup funds provided by the University of Utah to initiate the project, also supported by grants from Fondation Segré, the Sigrid Rausing Trust and the Whitley Fund.

Biology Student Stories: Bailey Landis

Biology Student Stories: Bailey Landis


April 3, 2024

by Maisy Webb

From playing the clarinet and majoring in music to finding inspiration in deciphering the As, Ts, Gs, and Cs relevant to fruit fly evolution and genetics, Bailey Landis has many interests but has dedicated his educational pursuits to biology.

The “major” shift happened when Bailey took Genetics from Nitin Phadnis. That was the moment he realized he loved biology and wanted to give research a try.

Bailey asked Phadnis if he knew of any lab openings, and the very next day he entered the research world…in the Phadnis lab! “Even though research was new to me, I was given the opportunity to jump into cutting-edge science. I immediately began investigating the genetic basis of a hybrid incompatibility between two subspecies of Drosophila.” Bailey artfully explained that “When two populations of a species are isolated from each other, they rapidly evolve [and this can] lead to speciation.” Deciphering the molecular and genetic basis of this process is the focus of the Phadnis lab.

Bailey finds the lab environment “unequivocally amazing” and  “is inspired by the motivation and drive of his peers in the lab.” He says, “Whenever you are doing something, people want you to do well ... and are not hoping for your downfall. So I have gotten courage knowing when I am presenting or doing something scary that people are hoping to see me succeed.”

Bailey has gained an appreciation for the collaborative nature of science, receiving mentorship and mastering new techniques with support from two other biology professors, Kent Golic and Clayton Dale. As it goes in research, things often don’t work and you always have to be on the lookout for something unexpected, Bailey shared. “I became frustrated that my hard work had yielded no results and began doubting whether the X-ray machine was working correctly. I examined the neuroblasts of mutagenized males, looking for fragmented chromosomes to ensure that the genetic material was being irradiated. ... My irradiation approach was simple and reliable [yet] lacked efficiency, relying on randomly mutating a single gene out of over 13,000. I felt like I was waiting for an accident and wanted my approach to be more precise. I returned to the drawing board, searching for a more efficient way to identify this gene. I pivoted to a targeted deletion system using CRISPR/Cas-9.”

Bailey’s enthusiasm and dedication has led to an evolution in his knowledge, which will definitely give him a head start when he begins his PhD in biology, at the U, in the fall of 2024.

Bailey is from Chico, California. When he’s not in the lab, you can find Bailey indulging his many other interests from drawing and painting, fly fishing, working on his jiu jitsu, snowboarding, and cooking lots of different dishes!

Where the Wild Things Went During the Pandemic

Where the Wild Things Went During the Pandemic


March 18, 2024

A new study of camera-trap images complicates the idea that all wildlife thrived during the Covid lockdowns.

Austin Green

In the early months of the Covid pandemic, when every bit of news seemed bleak, there was one heartwarming narrative that took hold: With humans stuck in their homes, the world was safe again for wild animals, which could now wander freely through cities, parking lots or fields that once might have been crowded with people.

But a new global study, which used wildlife cameras to track human and animal activity during the Covid lockdowns, suggests that the story was not that simple. Austin Green HBS'16, PHD '22 , currently post-doctoral researcher in the College of Science's Science Research Initiative, is one of the many co-authors and a leader in Utah in the collection of data of wildlife as it intersects with urban environments.

“We went in with a somewhat simplistic notion,” said Cole Burton, a wildlife ecologist and conservation biologist at the University of British Columbia, who led the research. “You know, humans stop, animals are going to breathe a sigh of relief and move around more naturally. And what we saw was quite different.”

Although humans disappeared from some places during the lockdowns, they surged into others, like parks that remained open when little else was, the researchers found. And there was enormous variability in how wild mammals responded to changes in human behavior. Carnivores and animals living in remote, rural places, for instance, were more active when people faded from the landscape, while the opposite was generally true for large herbivores and urban animals.

The study, which was published in Nature Ecology & Evolution on Monday, deepens and complicates scientists’ understanding of what has been called the “anthropause,” when pandemic lockdowns radically altered human behavior. It also highlights the nuanced ways in which humans affect the lives of wild animals, as well as the need for varied and multifaceted conservation efforts, the authors said.

“There’s no ‘one size fits all’ solution when it comes to mitigating the impacts of human activity on wildlife,” said Kaitlyn Gaynor, a wildlife ecologist and conservation biologist at the University of British Columbia. “Because we see that not all species are responding similarly to people.”

Ribosome adventures

Venki Ramakrishnan, 'My adventures in the ribosome'

 

Venkataraman “Venki” Ramakrishnan’s story is the stuff of fiction. He went from an eager undergraduate student in India to a self-described “failed physicist” to a major player in the race to uncover one of biology’s biggest mysteries—the structure of the ribosome, the most important molecule that nobody’s heard of that earned him a Nobel Prize in chemistry in 2009.

The opportunity to research the ribosome drew Ramakrishnan to the University of Utah in the late ‘90s. The ancient molecule brings him back as a Nobel laureate to discuss his “Adventures in the Ribosome” at the College of Science’s Frontiers of Science Lecture Series on Sept. 26, at the Natural History Museum of Utah. The evening should be enthralling—his popular memoir Gene Machine reads like a thriller that navigates inspired collaborations, friendly rivalries, and cutthroat competition behind scientific discoveries and international accolades.

“Why did my career work out? I didn’t go to any famous schools for my undergrad or graduate school, and I was sort of an outsider most of my life. I think there’s some sort of general lessons there,” Ramakrishnan said. “One of them is if you find things don’t work out, you have to be open to change.”

Ramakrishnan has never been afraid of change. He earned a PhD in theoretical physics at the University of Ohio, but immediately realized that developing theories and mathematical calculations wasn’t for him. The field of biology grabbed his attention.

“Every issue of Scientific American when I was a grad student was full of big breakthroughs in biology. That was a time when the first sequences of DNA were being reported, Ramakrishnan said. “Biology was going through this huge revolution, and it hasn’t stopped.”
