Honoring one of Holly’s past students, Loreto Godoy, the 8th annual Loreto Godoy Memorial Fellowship has been awarded to Neetha Iyer

Neetha Iyer is an ecologist from India who is fascinated by the complex interactions between animal behavior, disease, and the environment.

She is interested in understanding the factors that influence sociality and group-living. She is specifically curious about the ecological dynamics that influence how and why wild animals become infected with parasites. For her PhD dissertation, she is scratching this curiosity itch by studying the behavior and parasites of the critically-endangered Grauer’s gorilla endemic to eastern Democratic Republic of Congo. She is investigating whether social groups of gorillas serve as islands for parasite transmission, despite the high degree of home range overlap observed in the species. To answer this question, she is using genetic data from gastrointestinal nematode worms that are transmitted between gorillas through the environment.

In addition, she is interested in ecological factors that influence behavioral variation in this African great ape, a close relative to humans. She hopes her research can be used by wildlife managers and applied to conservation efforts to protect endangered primates and other animals that are increasingly threatened by deforestation and other human-induced environmental changes.

Holly Ernest was Loreto’s professor at UC Davis and looks forward to honoring the past student every year with the memorial fellowship.

mule deer in front of road

Melanie LaCava, Holly Ernest, and the Wyoming Game & Fish Department recently published a paper about Chronic Wasting Disease in mule deer, finding evidence that the disease is driving evolution in the species.

With WGFD, the team collected samples from mule deer throughout Wyoming, where chronic wasting disease has gradually spread over the past several decades. They found that a single genetic mutation linked to slower disease progression has become more common over time and that individuals with the slow mutation were less likely to test positive for the disease, providing evidence of disease-driven evolution in mule deer.

Marine Mammal Science Editors' Select Series. Presents: Reintroductions have saved the sea otter throughout North America: why should we care? with Dr. Shawn Larson

Holly Ernest & Erick Gagne recently assisted Dr. Shawn Larson on her award-winning paper: “Translocations maintain genetic diversity and increase connectivity in sea otters”, published in Marine Mammal Science.

The paper was awarded the Society for Marine Mammalogy Editor’s Select Series, and is available to the public to read for the month of July. Larson will be giving an online talk about the work on July 15, and the talk will be available on YouTube thereafter.

After the maritime fur trade left scattered sea otter populations with low genetic diversity, subsequent reintroductions have resulted in several new populations of sea otters in North America. Ernest & Gagne assisted Larson in sampling the genetic data of sea otters in California to study the genetic diversity, population structure, and geneflow of the groups. They found that genetic diversity was the highest in reintroduced populations – showing that translocation is arguably the greatest success in sea otter conservation.

Bighorn Sheep

Photo credit Melanie LaCava

Bighorn sheep research of Dr. Sierra Love Stowell in our lab published last week found that Wyoming bighorn sheep have distinct genetic populations.

This has important ramifications for conservation of this iconic ungulate. This is an interesting contrast with the low genetic differentiation of pronghorn in Wyoming also published within the week.

Dr. Love Stowell and coauthors followed the long-term impact of translocation of bighorn sheep, which is used as a wildlife management tool by the state. We found that there are at least five distinct genetic clusters of the sheep in the major mountain ranges in Wyoming. Our study also found there was high gene flow — genetic interchange due to movement of animals with resulting successful breeding — among herds that had translocation sources in common, and herds that received translocated individuals from other herds.

The southern part of the Great Gray Owl breeding range in the western US.

Range map: The southern part of the Great Gray Owl breeding
range in the western US. Dark gray outline delineates areas of documented breeding range in detail; red points represent unique sampling locations, and the number of individuals sampled.

Our lab’s new paper showing low genetic diversity in Great Gray Owls over a four-state region, led by M.S. graduate Beth Mendelsohn, published this week.

Lower genetic diversity in the owls means they adapt less quickly to changes in their environment, like fire, human development, stresses caused by viruses like West Nile, and other diseases. This study constitutes the first genomic work on Great Gray owls and the first genetic analysis that includes Wyoming, which represents the southern extent of the species range in the Rocky Mountains, impacted by habitat loss.

Pronghorn in field

A new paper published from our lab, led by PhD Candidate Melanie LaCava, found that pronghorn have little-to-no genetic differentiation throughout Wyoming.

Pronghorn populations in Wyoming span hundreds of kilometers across multiple mountain ranges and major highways. While pronghorn behavior is impacted by these obstacles, they exhibit flexible behavior – some seasonally migrate, some don’t, and they switch social groups. This could be the reason for the low genetic differentiation across the state.

Boomerang article

The largest land bridge in the world, to be built in California, and featured in the LA Times and the Laramie Boomerang, is based on some of our lab’s genetic data on the mountain lion named P22 (the Griffin Park/Hollywood lion)

Our lab has been studying California mountain lions (and P22) since the mid-1990’s, and their population genetic structure in the highly fragmented southern California landscape. This fractured genetic connectivity has shown to threaten southern California mountain lions. This land bridge should eventually help to decrease their mortality rates and increase genetic diversity. University of Nebraska (see John Benson’s work here: http://snr.unl.edu/aboutus/who/people/faculty-member.asp?pid=2374), UCLA, and UC Davis also contributed data and research.

Missouri Southern student Cameron Priester looks for snails

Our lab affiliate and collaborator, Dr. Kyle Gustafson’s lab at Missouri Southern State University, is studying snails & the impact of mining cleanup

Dr. Kyle Gustafson, along with student Cameron Priester, are researching the shell composition of snails from areas that have undergone significant cleanup efforts decades after the mining industry left its mark on the landscape. Most snails take up minerals from their surroundings, at least to some degree, Priester said. But what he hopes to discover is whether the snails absorbed anything more harmful, such as lead or zinc.

Journal cover & thumnail of website

Emily Graves and our collaborators at UC Davis have an interesting paper just out: Analysis of insecticide exposure in CA hummingbirds using mass spectrometry

The paper documents that hummingbirds found in California are exposed to insecticides, including neonicotinoids that are widely available and have detrimental impacts to native bees and other ecologically-important invertebrates. Part of the problem is that these chemicals are systemic and incorporated into the pollen and nectar of treated plants, where they come into contact with or are ingested by pollinating species – including hummingbirds. This work also documented minimally-invasive feather testing as a viable method for monitoring bird exposure to pesticides.

New paper published about the local extinction of Southern CA mountain lions isolated by urbanization

The local extinction of mountain lions within 50 years is possible for two isolated mountain lion populations in southern California’s Santa Ana and Santa Monica Mountains. The extinction risk is due to low genetic diversity and mortality that affects the stability of the population, based on DNA data generated by the work of our lab and assistance from Dr. Kyle Gustafson (when he was working in our lab) and Dr. Tracy Drazenovich (when she was working in Holly’s lab in UC Davis). But increasing connectivity could help — our model predicted that these populations can persist with relatively modest increases in landscape connectivity.

Desert Bighorn sheep

Our research article studying the genetic outcomes of translocation of bighorn sheep in Arizona published in The Journal of Wildlife Management

Holly, along with Daphne Gille at the University of California-Davis, led a seven-year study following the genetic structure and diversity of bighorn sheep using microsatellite and DNA data in 16 native and translocated bighorn sheep populations. They found that it’s possible to re-establish bighorn sheep populations without a reduction of gene diversity and without erosion of ancestral lineage – great news for translocation efforts, which are often used in wildlife management to increase population abundance to threatened species, restore animals to their historical range, and preserve biodiversity, among other goals.

mountian lion

Our paper about California mountain lion populations becoming splintered as a result of development getting national attention

The new study, titled “Genetic Source-Sink Dynamics Among Naturally Structured and Anthropogenically Fragmented Puma Populations,” was published Dec. 10 in Conservation Genetics, and found that habitat fragmentation is splintering California’s mountain lion (Puma concolor) populations. As urbanization between Los Angeles and San Diego spreads across landscapes historically used by mountain lions, it is causing some groups of mountain lions to become less genetically diverse, and is leading to inbreeding, raising concerns about the populations’ long-term health.

The paper is now featured on the home page of The Wildlife Society’s website. Read the article here: http://wildlife.org/development-is-dividing-californias-puma-populations/

Loreto Godoy holding bird

Honoring Loreto Godoy, one of Holly’s past students, the Loreto Godoy Memorial Fellowship has been awarded to Gina Tarbill

In her Ph.D. research, Gina uses pollination networks in post-fire forests as a model system to better understand community dis/assembly, network dependence and vulnerability, and the community response to species invasions or extirpations after large-scale disturbance. She hopes to improve our understanding of how pollinators, particularly hummingbirds, use post-fire habitats during breeding and migration to identify important plant species or communities.  Gina’s passion for increasing diversity and inclusion in STEM fields has led her to volunteer to teach science, critical thinking skills, and environmental stewardship to students from underserved elementary schools in the Sacramento area with Sierra Nevada Journeys. After completing her Ph.D., she plans to continue teaching and conducting research in community ecology. Gina enjoys birding, hiking, kayaking and traveling with her family.

Holly Ernest was Loreto’s professor at UC Davis and looks forward to honoring the past student every year with the memorial fellowship.

New paper accepted to Journal for Nature Conservation: Optimal DNA blood extractions on preservation paper limits conservation genomics, not genetic applications.

Sierra M. Love Stowell, Erin G. Bentley, Roderick B. Gagne, Kyle D. Gustafson, Linda Y. Rutledge, Holly B. Ernest.

The paper covers the challenges of collecting and preserving biological samples from rare and elusive wildlife species. Blood samples on preservation paper are commonly used across a wide range of animals as a convenient and non-destructive method to obtain and store DNA. While this method has been successfully used for genetic applications, genomic methods require large quantities of high-quality DNA and paper preservation methods can limit DNA availability, especially for mammals which have non-nucleated blood cells. Thus, high-yield DNA extraction methods are required to providing adequate unfragmented DNA for downstream genomic applications. We recommend that researchers optimize their extraction methods and consider collecting fresh blood or tissue for genomic applications.

Hummingbird in hands

It’s pollinator week!

In honor of Pollinator Week (http://pollinator.org/pollinator-week), the Wildlife Genomics and Disease Ecology Lab would like to highlight their work on hummingbirds: important but perhaps underappreciated pollinators. The conservation genetics and population health work by Holly Ernest, Brady Godwin, and collaborators helps to better understand the ecology, health, and diseases of these birds throughout the Rocky Mountains and the American West. Support our pollinator friends this week and throughout the summer!

Brady & Holly completed a field work hummingbird road trip to the Bighorn Mountains last week (June 10-14, 2018)

They took the Humm-Mobile, mobile lab, to fill a remaining sampling gap for Brady’s Broad-tailed Hummingbird research. Many thanks to our Bighorn Mtns site hosts, a private family ranch (Thanks Charlie and owners!) and the HF Bar Ranch (Thanks Margi, Richard, and Ranch staff! http://www.hfbar.com/).  Many thanks as well to those who helped us make connections to good hummingbird study sites, including the Wyoming Game and Fish Department and Nature Conservancy Buffalo, WY regional offices.

Using next-generation DNA sequencing, genomic research techniques, geographic information systems (GIS) to map locations, field identifications, and health exams of individual birds, we are examining population biology and hummingbird health, including genetic diversity and disease ecology.

We’ll keep you updated on what we find out!

Sea otters

New sea otter conservation genetics paper accepted to Evolutionary Applications: Measures of effective pop. size reveal special considerations for wide-ranging species.

The paper provides analyses and data vitally necessary for southern sea otter (SSO) recovery.  This very small subspecies has been hovering at a few thousand animals along the California coast, and has been hit hard by diseases including Toxoplasma brain disease and others, as well as shark attacks and illegal shootings.  We provide evidence that SSO genetic diversity is low and staying low – even with modest increases in population numbers, genetic diversity has not increased.

The paper also examined one of the methods that is included in the US Fish and Wildlife Service’s southern sea otter recovery plan, “effective population size” (Ne), and shows that the way Ne is calculated can make important differences in the final number.  The US Fish and Wildlife Service uses Ne to determine when the SSO is to be delisted as a federally Threatened Species.  If they use old methods, the SSO may be delisted too soon for true recovery.

Mule Deer

Chronic Wasting Disease and mule deer population genetics in WY

With mule deer declines and diagnosed cases of Chronic Wasting Disease (CWD) increasing across Wyoming (most recently in Meeteetse), it’s more important than ever to look at how disease, genetic diversity, migratory movements, and land development and use activities in Wyoming are interacting to impact population health and numbers of mule deer.

Before this new study, there has been no comprehensive statewide population genetic and CWD genotype analysis of Wyoming mule deer. Providing such an analysis will allow wildlife agencies including the Wyoming Department of Game and Fish to better manage and conserve mule deer.

Holly giving Saturday-U talk
Saturday-U

Holly presented “Giving a Hoot about Wildlife Genetics: Enhancing the Survival of Western Wyoming’s Bighorn Sheep and Owls” at the Fall 2017 Saturday U at the National Museum of Wildlife in Jackson Hole.

Genetic diversity is key to the long-term survival of a healthy population of any animal species. This is even more true for threatened species near Jackson, like Bighorn Sheep and Great Gray Owls. Holly and her lab study these herds and flocks to work out their genome and help wildlife and land managers evaluate ways to assist in their long-term survival.

Saturday University is a collaborative program connecting popular University of Wyoming professors with Wyoming residents who have a desire to learn.

Honoring one of Holly’s past students, the Loreto Godoy Memorial Fellowship has been awarded to Phillip Brand

Philipp Brand received the 4rd annual Loreto Godoy Memorial Fellowship for 2017-2018. Philipp is an evolutionary biologist interested in speciation and sensory evolution in insects (the most abundant wildlife on earth!). Phillipp is interested in the sensory biology, neurophysiology, chemical ecology, and olfactory memory involved in pheromone communication and the underlying molecular mechanisms through which these evolve. His main focus is the evolution of chemical communication in orchid bees, a charismatic group of insects known for their unique “perfume collecting” behavior. Male orchid bees collect scents from flowers and non-floral sources such as rotting wood or fungi to concoct a species-specific chemical mixture we call ‘perfume’. The accumulated ‘perfume blend’ is eventually released in order to attract conspecific females for mating.

He holds a Masters of Science in Biology (Genetics and Evolution) and a Bachelor of Science from Heinrich-Heine-Universität Düsseldorf. He is currently a PhD student in the Santiago Ramirez Lab at the Center for Population Biology at UC Davis as a PhD candidate in the PopBio Graduate Group. Learn more about Phillipp

Holly Ernest was Loreto’s professor at UC Davis and looks forward to honoring the past student every year with the memorial fellowship.

Science Olympiad a success!

Beth Mendelsohn, Melanie LaCava, and Brady Godwin volunteered to create, administer and grade the ecology exam for the Wyoming State Science Olympiad Tournament (held in Casper this year). Their exam included museum skulls, microscopes, and food webs among other things for teams of middle and high school students – who participated for fun!

One sample question below… can you answer it?

What type of species interaction (competition, mutualism, commensalism, parasitism, predation) is each of the below strategies?

_________________Bees use flower nectar for food, and while collecting the nectar transport pollen from one flower to the next
_________________Algae and Fungi come together to create Lichens, fungus gets energy from the algae, and the algae get a moist protected habitat
_________________Red-breasted nuthatches excavate small cavities in dead trees for nesting
_________________Mountain pine beetles lay their eggs under the bark of pine trees. When the larvae hatch, they feed on the phloem of the tree, disrupting nutrient transport
_________________Pine martens hunt and eat squirrels

Answers, in order: Mutualism, Mutualism, Commensalism, Parasitism, Predation

Presentation screenshot of Genetic assessment of CA sea otters

Erick traveled to Seattle to present genetics of threatened southern sea otter at the 10th Annual Sea Otter Conservation Workshop

Erick Gagne traveled to Seattle to present genetic research on the threatened southern California sea otter at the 10th Sea Otter Conservation Workshop. The international conference is held in the Seattle Aquarium and is the largest meeting of sea otter biologists in the world. Our findings reveal that genetic diversity is not increasing over time despite an increase in sea otter population size. In addition, we explore multiple estimators of the effective population size, which is estimate of the number of individuals in the population that are contributing genetically. Accurate estimates of effective population size are important because maintaining an effective population size of 500 is considered necessary for long term conservation and is a part of the criteria for delisting southern sea otters as a threatened species.

Our paper investigating tool-use by sea otters, published in Biology Letters!

Our new paper investigating tool-use by sea otters, lead by our collaborator Katherine Ralls, has been published in Biology Letters! The evolutionary and ecological roots of tool-use vary greatly across taxa. Within marine mammals, the best examples of tool-use are sea otters and Indo-Pacific bottlenose dolphins. In both species, tool-use is not implemented by all individuals even within a population. Genetic analyses of the bottlenose dolphins revealed that tool-use was related to a single matriline (mother to offspring lineage) and that tool-use transmission is likely cultural (where individuals learn tool-use by observing other members of their group). In sea otters, however, we found no association between relatedness or mitochondrial haplotypes with tool-use. Instead, our work suggests a predisposition of all sea otters to use tools when faced with certain ecological conditions.

New Project in Lab: Cutthroat Trout Genomics

Sierra Love Stowell received a contract from the United States Fish & Wildlife Service to genotype 190 greenback cutthroat trout at the Leadville National Fish Hatchery in Colorado. The genotypes will be used to calculate relatedness, which will then be used to choose parents in controlled matings. The goal is to maximize genetic diversity by mating unrelated individuals and ensure the sustainability of the broodstock in the hatchery and the success of reintroductions into the native range.

pronghorn in field

The Wildlife Society recently published an article on our pronghorn migration genomic research

Melanie LaCava, along with Holly Ernest, are studying the genetics of pronghorn populations and their movements across Wyoming. The Wildlife Society article explains: “We know that highways are definitely barriers for seasonal movements. What I’m hoping do is provide information on whether they’re also acting as a genetic barrier,” LaCava said. “There have been two [wildlife highway overpasses] built in Wyoming recently and they’re looking to build more. What I’m hoping to provide is an extra layer of information to help inform decisions like that.”

Ernest’s 20-year research featured in UW’s Reflection Magazine

Holly Ernest’s research on mountain lions over the last 20 years is currently featured in UW’s Reflection Magazine. She and her team of students and collaborators provided important new insights into the ecology, genetics, and health of mountain lion populations. Previous to these studies, some wildlife professionals assumed mountain lions were broadly interbreeding, that there would not be much structure to their populations, and that western mountain lions would have healthy levels of genetic diversity. DNA evidence has proven this is not the case in California.

Mother and Child Black Bear

Lab receives new funding for 3-year study of black bear populations

Kyle Gustafson and Holly Ernest are studying the DNA and population of black bears, funded with a new three-year grant. Working with wildlife agencies to collect and analyze the hair samples of these bears, they study DNA mark recapture (how many times the same bears – versus new bears – are recaptured in the same location, based on DNA samples). Using this data, they can statistically determine the population of bears in a given area.  Currently, they’ll be looking at bears in the Eastern Sierra Nevada range, along with the mountain ranges around LA.

mother Southern Sea Otter with baby

California sea otter genetic research presented at Wildlife Disease Assoc. conference

Holly Ernest presented her and Erick Gagne’s research on the endangered southern California sea otter at the Wildlife Disease Association’s 2016 conference in Cornell University. Their research shows that the genetic diversity of these sea otters has stayed low and static over the last ten years.

Low genetic (DNA) diversity has adverse effects on populations, like the sea otters near Monterey Bay, limiting their ability to fight disease, climate change, predators, and more. Genetic variation within a population results in differences in how individuals can adapt and survive. This provides the variable raw material to allow populations to evolve in the face of novel threats. For example, if a population’s immune system is limited (low genetic diversity of immune system) to fighting only specific viruses, then one new disease could potentially eliminate most or all of the animals. In contrast, if individuals within the population have a variable immune system, they may be well-equipped to fight off the new disease.

In the past before the mid-1800’s fur trade era, sea otters used to inhabit almost the entire Pacific coast – from Mexico, to Alaska, the Bering Strait, down to Japan. Now fragmented, the population in California is isolated from breeding from other genetically diverse populations. California sea otters today suffer from an onslaught of disease threats and loss of their marine kelp habitat.

Hummingbird migration of Penny

We’ve followed Penny, a broad-tailed hummingbird, the last two summers

We’ve banded and followed Penny, a broad-tailed hummingbird, over the last two summers in Wyoming – and she migrated to southern Mexico in the interim! Holly Ernest and Brady Godwin banded Penny as a young hummingbird in late August last year near Fox Park, Wyoming. A year later, they were able to study her again in June, in the same location, where she’s likely returned to nest and reproduce. Hummingbirds like Penny make an incredible 4000 mile round-trip migration through a gauntlet of obstacles – dogs and cats (some of their main predators), glass windows on high-rise buildings, pesticides, cars, and exhaustion – eventually reaching southern Mexico, in the area of Oaxaca and surrounding Mexican states. They pack up to 1.8 grams of fat under their chins (gaining ~50% of their normal body weight) to make the 2-month journey. Both Penny’s winter and summer habitat are high elevations with open woodland and flowering shrubs – and sometimes, when returning to Wyoming in the late Spring, even sees snow!

Kyle Gustafson with conference group

Lab member Kyle Gustafson attends spatially-explicit capture-recapture workshop

A fundamental question in wildlife conservation is “What is the population size?” Although counting individuals seems simple, estimating population size is extremely complex. Wildlife populations that we study are not limited to a single location, and a better question might be “What is the population density and how does it change among locations?” To learn the techniques required to answer this question, Dr. Kyle Gustafson attended a Spatially-explicit capture–recapture modeling workshop at the University of Georgia, led by Andy Royle and Richard Chandler.

Wildlife Genomics workflow showing wildlife samples, DNA extraction, analysis, and reports

Using samples from wildlife to extract and analyze DNA

We are using tissue, blood, horn, hair, and even fecal samples from wildlife populations to extract DNA and analyze genetic information to learn about population history, health, and dynamics. We’re then sharing that information with stakeholders in wildlife conservation, from citizens to state and federal wildlife agencies, so that they can make informed decisions about wildlife management.

STUDYING ECOLOGY OF FERAL PIG POPULATIONS & HOW THEY INTERACT

Working with the USDA (U.S. Department of Agriculture) wildlife genetics unit Dr.Toni Piaggio and Dr. Michael Tabac, our lab is studying the ecology of feral pig populations in California.  Feral pigs, also called wild boars, or feral hogs, are very environmentally destructive, basically rototilling up whole hillsides and destroying native grasses and other plants.  Our study specifically uses population genetic and ecological data to determine breeding structures of pigs, how populations of pigs are grouped across the landscape, and what important social factors are associated with human-assisted movement of feral pigs. This information will be used to better understand the lifestyle of these unique and invasive animals as well as how to manage feral pig populations and the diseases they can spread to livestock, wildlife, and people.
