Alex received his B.S. in Biology from the National Autonomous University of Mexico. He then obtained a PhD in Natural Resources (with emphasis in Wildlife Management and Conservation) from the University of Arizona, where he focused on topics related to population genomics and genetics of endangered mammals, particularly of different felid species.  In this regard, Dr. Ochoa has published scientific articles describing the evolution and demographic history of pumas, and the effects of multiple genetic introgression events in the Florida panther gene pool.  Alex has also collaborated on projects evaluating the genetic diversity and structure of jaguars and ocelots from the U.S.-Mexico border, and occurrence and diet of pumas and jaguars from Sonora, Mexico.  As a current postdoctoral scholar at the University of Central Florida, Alex continues research with population genomics questions associated with wildlife management and conservation.

 

Ron Thompson

Treasurer 2026-2028

Ron is a graduate of the University of Arizona with a Bachelor of Science in Wildlife Biology. He worked as the large carnivore biologist for the Arizona Game and Fish Department.  Ron is the executive director for the nonprofit primeroconservation.org and most recently worked on a lion density study in NW Arizona. He is on the WFA election committee and has been a past Council member and Secretary of WFA. His nonprofit works to reduce puma predation on livestock in Sonora testing the non-lethal method of using conditioned taste aversion.  He has worked as a research associate with Borderlands Research Institute at Sul Ross State University documenting the diets of mountain lions in western Texas. The results of that study supported the Texas lion working group committee to submit and see passed the first-ever changes to the trapping laws for lions in Texas. For the past 15 years his nonprofit has been working with private ranch owners in Sonora, Mexico and documenting the prey off take by jaguars and puma to better inform communities and local ranchers that healthy native prey populations reduce predation by apex carnivores.

 

Winston Vickers

Winston Vickers

Councilor Overseeing Scholarships 2025-2027

Winston obtained his Doctor of Veterinary Medicine (DVM) degree at Oklahoma State University, and after a period in veterinary practice obtained a Master of Veterinary Preventive Medicine (MPVM) degree focused on the epidemiology of wildlife disease and wildlife ecology at UC Davis.   For the last 21 years he has been a wildlife research veterinarian working with the UC Davis Wildlife Health Center (UCD-WHC), a division of the One Health Institute at the School of Veterinary Medicine.  He co-directs their California mountain lion and wolf studies, and also works with the Institute for Wildlife Studies of Arcata, CA (IWS) on mountain lion and other wildlife projects.  He has participated in research into the ecology, sources of mortality, connectivity, infectious diseases, genetics, and parasites of many species, including mountain lions, bobcats, Channel Island foxes, gray wolves, Santa Cruz Island scrub jays, cactus wrens, bald eagles, and waterfowl.  He has conducted research into cancer in Channel Island foxes, and has participated in recovery efforts and monitoring of island fox populations across their 6-island range.  He has also worked with wildlife affected by oil spills in association with the Oiled Wildlife Care Network at UCD-WHC.  He co-developed and directed a series of short and full length documentary films about mountain lions.  He collaborates with numerous researchers from other universities, the California Department of Fish and Wildlife, highway and other governmental agencies, and NGO’s on mountain lion and other wildlife issues.

Mark Lotz

Mark Lotz

Past President 2026-2028

Mark’s wildlife career has been devoted to studying the Florida panther, a population of puma in south Florida.  When he began his wildlife biologist job with the Florida Fish and Wildlife Conservation Commission nearly a quarter century ago, Florida panther management had just entered a new era.  Florida’s experimental genetic restoration, by releasing 8 female pumas from Texas into south Florida, proved to be successful and changed this small and inbred population into a more robust panther population.  However, this success led to many new challenges as panther numbers increased and they began repopulating habitats adjacent to people.  Mark’s field experience includes capturing individuals for radiocollar studies, handling neonates at dens, and locating study animals from a fix-winged aircraft to monitor population demographics for genetic restoration.   With an increased panther population, much of Mark’s time is devoted to managing human-panther conflicts, investigating depredation complaints and working with residents to resolve their predator conflict issues.
