President 2016-2018; V.P. Latin America 2012-2015.
Anthony J. Giordano is the founder and executive director of S.P.E.C.I.E.S., an organization dedicated to the conservation of the world’s carnivores and the ecosystems that support them.  He holds a double major B.Sc. in zoology and environmental science, a M.Sc. in conservation biology and applied ecology, and a Ph.D. in wildlife science and management.  For his doctoral work, Anthony investigated the population status and genetics of jaguars in the Gran Chaco of Paraguay, where he received a Fulbright Scholarship for his jaguar conservation, landowner outreach, and capacity-building efforts.  Anthony has extensive experience with felid conservation issues and has field experience with a diversity of species, including pumas, clouded leopards, fishing cats, lions, leopards, tigers, jaguarundis, and ocelots  He is a member of the IUCN Cat Specialist Group and The Explorer’s Club, serves on the Conservation Committee for the American Society of Mammalogists, and is an active board member for the Latin American section of the Society for Conservation Biology.  He has also published several dozen peer-reviewed scientific and popular articles. Anthony is a former Wild Felid Legacy Scholarship recipient (2010), and makes regular contributions to the Wild Felid Monitor

Mark Lotz

Mark Lotz
Vice President, North America 2016-2018
Mark earned his bachelor’s degree in Wildlife Management from Ohio State University in 1992.  He is currently a Biological Scientist with the Florida Fish and Wildlife Conservation Commission (FWC) and has been studying Florida panthers since 1994.  Mark began his career with FWC at a pivotal time for panther conservation as genetic restoration of the isolated and severely inbred Florida panther population began. This management and monitoring project continues to this day.  His typical field duties have emphasized capturing, collaring, and tracking – from the ground and air - all age classes of panthers for long-term radio telemetry studies to monitor population demographics for genetic restoration and conservation of the species.   As a member of the capture team, he acts as the tree-climber, safely extracting anesthetized panthers from the tree tops.  Some of Mark’s past projects have included evaluating the effectiveness of various wildlife underpass designs, determining the feasibility of extracting DNA from scats, and defining panther prey selection on cattle ranches using GPS cluster point data.  As the Florida panther population has increased, Mark’s duties have evolved and he now is the principle investigator managing human-panther conflicts.  This typically entails investigating the loss of hobby farm animals (i.e. goats), providing living with wildlife knowledge to residents, and acting as liaison with NGO’s to provide further assistance with resolving predator conflicts.


Sandra Ortiz

She undertook a one-year internship in zoo animal medicine and husbandry at national zoos and has worked in clinics and private hospitals intermittently. She has participated as field veterinarian in several field projects with bats, rodents and carnivores and did a research internship at EcoHealth Alliance. From 2008 to date she has worked as field veterinarian for the “Jaguar and puma conservation project in the Calakmul Biosphere Reserve (CBR)” from the Institute of Ecology, UNAM and works also for two other jaguar projects in the Yucatán Peninsula in southern Mexico. Sandra has attended and presented lectures at several conferences, workshops and meetings of jaguar conservation, wildlife anesthesia and conservation medicine. She is currently finishing her Master of Animal Health Science at UNAM and her research project is focused on determination of the prevalence of exposure to canine distemper virus (CDV) of jaguars, pumas and domestic dogs in the surroundings of the CBR, tutored by top ecology and jaguar researchers Gerardo Suzán, Gerardo Ceballos and Sharon L. Deem. Sandra is curently field representative for Wildlife Pharmaceuticals Mexico and continues to develop her research project of carnivore diseases in Calakmul and the creation of a veterinary advisory group for jaguar and puma conservation strategies in Mexico.

Ken Logan

Ken Logan
WFA Secretary, 2016-2018.
Ken has a Bachelor’s Degree in Range & Wildlife Management, a Master’s Degree in Zoology & Physiology, and a Ph.D. in Wildlife Sciences. He has been involved in puma research and management applications for the past 34 years, involving 4 puma populations in Wyoming, New Mexico, California, and Colorado. Currently, Ken is a Mammals Researcher for Colorado Parks and Wildlife. Ken’s puma research has covered a broad range of topics, including population dynamics, behavior, social organization, puma-prey relationships and human-puma interactions. In those efforts he led two 10-year studies on puma populations in New Mexico and Colorado that involved experimental manipulation of the populations to address a variety of biological and ecological questions. Significant contributions from those works as they pertain to puma science, management, and conservation (and possibly to other big cats), include: the reproductive strategies hypothesis, source-sink demographic dynamics with application to a wide range of options through zone management, and puma—ungulate prey—habitat interactions that help us better understand population-level effects of predation and effects of sport-hunting on puma populations. Ken has authored and co-authored a number of professional papers, book chapters, and a book titled: Desert Puma: Evolutionary Ecology and Conservation of an Enduring Carnivore in 2001. The book was awarded The Outstanding Publication in Wildlife Ecology and Management by The Wildlife Society in 2002.
