Dr. Ann Hedrick elected as a Fellow of the Animal Behavior Society

Dr. Ann Hedrick was recently elected a Fellow of the Animal Behavior Society, an honor that acknowledges a “distinguished contribution to the field.” Her research, mainly conducted on crickets, focusses on mate choice, anti-predator behavior and animal personalities, and has been funded by the National Science Foundation and the Academy of Finland. She is currently working on a collaborative NSF grant with Dr. Ned Dochtermann (North Dakota State University) on the genetic architecture of “behavioral syndromes” (suites of correlated behavioral traits).

Professors John Eadie and Gail Patricelli were chosen for the Academic Senate Distinguished Teaching Award for 2018.  This award is given to outstanding teachers who have had an extraordinary impact on their students. 

Professor Eadie, from the Department of Wildlife, Fish and Conservation Biology is notable for this welcoming and engaging style in the classroom, as well as his sincere concern for the well-being of his students.  His courses in Wildlife Biology and specifically on wild birds are extremely popular, even legendary, with students enthralled by his creative descriptions and extemporaneous stories.  And John does it while maintaining high expectations and instructional rigor.  Not only do students at all levels rave about his charisma and ability to translate complex information in a stimulating manner, but his colleagues laud his innate talent as an educator and mentor as well. 

Professor Patricelli excels at teaching at many different kinds of courses: huge lecture classes, small upper-division courses, breadth classes for non-majors, and individual mentoring of undergraduates in research.  She has supervised more than 300 undergraduates in laboratory and field projects.  She is known for her innovative assignments.  She asks students to find case studies of “Baloney Science” – examples of distortion of scientific research.  Students compare their case study to the original scientific publication and analyze the false representation of the findings.  In their evaluations, her students identify Patricelli’s dedication, enthusiasm, and creativity as qualities that make her an extraordinary teacher.

Cameron Jones, Ryane Logsdon, and Alexandra McInturf awarded an Animal Behavior Society Student Research Grant

The Animal Behavior Society’s Student Research Grants are designed to provide resources for junior graduate students to investigate proposed research topics that push the field of animal behavior.

Cameron’s proposal to study the role of behavioral phenotypes on invasive and native species interactions combines ecological and lab-based studies on the invasive brown widow, Latrodectus geometricus, and native western black widow, L. hesperus. The goal of this study will be to provide insight into the behavioral mechanisms that facilitate the establishment of invasive species. In doing so, Cameron hopes to begin providing a framework for understanding the interaction between behavioral variation and species invasions and its associated ecological effects.

Ryane's proposal, The Impacts of Habitat Structure on Social Network Structure, Information Flow, and Behavior in a Lek-Based System, will help to advance her work on the impacts of habitat and the social environment on greater sage-grouse (Centrocercus urophasianus) communication and mating behavior. With the help of this grant (and some amazing collaborators at Boise state), Ryane will be able to use high-resolution mapping technology to quantify the sage-grouse lekking habitat. The goal of this work is to combine this ground-based LiDAR technology with behavioral recordings to uncover how sage-grouse interact socially in the naturally-variable microhabitat of a lek.

Alex’s proposal, “Critical tracking studies of basking sharks for conservation management in the Irish Sea”, outlined the methods and outcomes for a pilot study using active tracking on migratory basking sharks in a known hotspot off of Malin Head, Ireland. A collaboration with Queen’s University, Belfast and the Irish Basking Shark Study Group, this study aimed to determine the drivers of movement in a basking shark population that annually returns to Malin Head in order to obtain more accurate population censuses. The number of apex predators that the environment can support will serve as an indicator of ecosystem health, contributing to the establishment of more effective conservation policies. This study was also designed to examine variation in basking shark behavior based on size and sex, which could be predictors affecting hotspot use in this population. Significantly, data for this project is collected using short-term acoustic tracking, a technique that has yet to be applied to this species.

Through this program, graduate students develop a project that addresses a challenge associated with graduate education and postdoctoral training. Alli's project focuses on training graduate students and post docs on inclusive mentoring, with the specific goals of providing mentors with effective and efficient strategies to maintain a diverse group of undergraduate mentees. 

October 2016

Donald R. Williams, a 1st year graduate student in Karen Bales’ lab, recently published two papers

The first was a first-author manuscript investigating oxytocin (OT) as an experimental therapeutic for schizophrenia published in the journal Psychoneuroendocrinology. Donald’s primary research investigates the opposing effects of OT on social behavior by characterizing oxytocin receptor (OTR) activation of distinct intracellular signaling pathways in prairie voles (Microtus ochrogaster), a social monogamous species. His research will have two broad implications: 1) elucidating the basic biology of social behavior; and 2) providing a foundation from which to build translational work for individuals that suffer from social disorders, such as schizophrenia and autism.


His second paper exploring quantitative methods, such as meta-analysis, from a Bayesian perspective was accepted for publication in the journal Psychological Science.  Donald learned early in his career that a commonality between all disciplines is statistics and that reasonable inferences are dependent upon properly specified statistical models. This realization and passion has allowed for international collaborations with researchers from Canada, Germany, and Sweden. While not directly related to the field of animal behavior, his publication in Psychological Science contributes to our shared body of knowledge concerning quantitative methods and thus ensuring rigor in the scientific literature. Moreover, Donald is a proponent of Bayesian multilevel modeling and will use these techniques to answer questions about animal behavior.

Myfanwy Johnston awarded the Leland Roy Saxon and Georgia Wood Saxon Fellowship

I am thrilled and honored to accept a Leland Roy Saxon and Georgia Wood Saxon Fellowship.  My Ph.D. research at UC Davis focuses on native migratory fish species in the floodplain of the Central Valley.  The project began in 2012 with the overarching goal of investigating the movement behavior of different types of migrants in the Yolo Bypass, an intensely altered seasonal floodplain in the Sacramento-San Joaquin Delta.  The Bypass, which occupies the extensive historic floodplain of the lowermost Sacramento River, is managed for a mix of uses, including farming, riparian and managed wetland habitat, tidal marsh habitat, upland and grassland habitat, and flood control.  Given substantial evidence over nearly fifteen years for its benefits to native fishes during flooded periods, the Bypass has become the focus of interest in managing seasonally flooded habitat in the Delta.  Upon completion, this project will compare and contrast the movements of semelparous and iteroparous migrant types (Chinook salmon and white sturgeon, respectively) while navigating the Yolo Bypass, as well as the factors affecting their migratory success, which may include life stage, migratory route, and response to passage barriers.  Understanding how these animals move through their environment is a fundamental part of determining how the landscape is best managed to promote successful migrations while still supporting human demands.

Conor Taff publishes a paper in the Proceedings of the Royal Society of London B

Conor Taff, who recently completed his PhD and won several major awards (see below) published a paper in the Proceedings of the Royal Society of London B entitled, “Fluctuations in Neighbourhood Fertility Generate Variable Signaling Effort”.  In this paper, Taff and his co-authors used autonomous recording devices and song detection algorithms to characterize singing throughout the breeding season in a population of Common Yellowthroat warblers. This approach allowed them to identify over 115,000 songs produced by focal individuals in our population over two breeding seasons. Using these data, they found strong evidence that males sing less when their mate is fertile, but sing more when females on nearby territories are fertile. This result is consistent with the idea that males maximize their breeding success by avoiding cuckoldry on their home territory, while simultaneously advertising their availability to extra-pair mates. The patterns that they observed suggest that males monitor a complex social environment and adjust their singing effort to match subtle changes in female fertility on territories up to 400 meters away.

Congratulations to Conor Taff for winning a trifecta of major awards in 2014!

Conor was awarded the Merton Love Award for Outstanding Dissertation in Ecology and Evolution at UC Davis, which goes to the student with the most outstanding PhD dissertation in the fields of ecology and evolutionary biology at UC Davis each year.  Conor was also awarded the Cooper Ornithological Society Young Professional’s Award, which is given to two young scientists each year for outstanding research and contributions to the ornithological profession. To top off his winning streak, Conor was awarded the Animal Behavior Society Warder Clyde Allee Award for best paper and oral presentation by a finishing PhD student at the Animal Behavior Society meeting at Princeton University.  These are all the top awards given to young scientists in their fields.  Conor was awarded a PhD in Animal behavior in 2013 working with Professor Gail Patricelli at UC Davis, and is now a USDA postdoctoral fellow with Professor Andrea Townsend at UC Davis.

Conor’s winning the Allee Award, the top award for a young animal behaviorist in North America continues a strong UC Davis tradition.  In recent years, other UC Davis students winning this award include Aaron Rundus in 2006, Karen Mabry in 2007 and Julia Saltz in 2012.  Conor’s major advisor, Gail Patricelli also won the Allee Award in 2002.

Andy Sih was the vice chair and co-organizer of the first Gordon Research Conference on Predator-Prey Interactions in Ventura, CA
Andy Sih was the vice chair and co-organizer of the first Gordon Research Conference on Predator-Prey Interactions in Ventura, CA, January 5-10, 2014. The theme was an interdisciplinary approach to understanding effects of fear on individuals (including human PTSD), populations, communities and ecosystems. Andy gave the closing talk on developing a theoretical framework to better understand responses of naïve prey to exotic, introduced predators. What explains why some prey respond appropriately to novel predators that they have never seen before, while other prey suffer high death rates because they do not respond well to novel predators?

Sean Ehlman attends workshop in Trondheim, Norway
ABGG student and Sih lab member Sean Ehlman attended a workshop on "Evolution in Stochastic Environments" attended by a select group of both empiricists and theoreticians working on the myriad types of adaptations to environmental unpredictability. Sean presented two recent models: one on bet-hedging in a heterogenous landscape and the other on predator/prey detection theory in uncertain predation regimes.
