The Memphis Zoo has a very active conservation department with six full time research positions, crossing a wide range of biological disciplines. In addition to our senior biologists, we also have a close working relationship with many academic faculty from regional universities that we have established research associate positions for similar to an adjunct arrangement.

How I Help Save Wildlife: lead Memphis Zoo's efforts to understand and protect wildlife. This work extends beyond the zoo itself to directly benefit animals in nature. For example, we're helping to restore giant panda habitat in China, reduce elephant poaching in Africa, and discover new populations of amphibians in the U.S. I work to safeguard all wildlife, but my passion is helping people get excited about species that aren't 'cute' or 'fuzzy', like the slime-covered hellbender, the bug-eyed gopher frog, or 5-foot-long pine snake. Trust me, once you get to know these rare and fascinating critters, it's easy to understand why we're fighting to ensure their survival alongside the adorable giant panda and the majestic African elephant.
Why I Love Science: I'm fascinated by life at its most basic level - cells and molecules. As a wildlife scientist, I work to understand how tiny processes in an animal can provide clues about big threats like climate change or habitat loss. For example, I'm studying immune cells in salamanders housed at different temperatures to help understand if these animals can survive a warmer climate. My research interests include wildlife physiology and reproduction, diseases of amphibians and reptiles, and unconventional approaches to monitoring wildlife populations in nature. These interests have taken me across the globe, from China to Africa, but my most exciting wildlife encounters have been right here in the U.S.
My Favorite Places to Work: The southern Appalachian Mountains and the Louisiana Gulf Coast
Dr. Lu ZhangPost-Doctoral Research Fellow
Academic Background: Ph.D. in Zoology
with a concentration in Wildlife Conservation, Peking University, Beijing,
China; B.A. in Beijing Technology and Business University, Beijing, China.
Conservation interests: wildlife
management, GIS-based habitat modeling, herpetology, forest ecology, conservation policy, wildlife-livestock
Current research direction/interests:
Dr. Zhang is now working in the Chinese Giant Salamander reintroduction project. As the largest amphibian in the world, the salamander is listed as Critically Endangered on the IUCN Red List. Although there are few populations remain in the wild, a large number of giant salamanders are bred in farms in China. The reintroduction project includes purchasing salamanders from breeding farms and releasing them into their original habitat, tracking them by Passive Integrated Transponder (PIT) tags and radio transmitters, and analyzing the environmental factors (e.g., temperature, water properties, climate, and forest type) that may affect the movements and survival of reintroduced salamanders. The results of the project
will provide guidelines for future reintroduction efforts to maintain Chinese giant
salamander populations in the wild, as well as to improve living condition for
giant salamanders kept in breeding farms. In the spring of 2013, about 30 giant
salamanders will be released into streams in the Qinling Mountain in China, and
monitored weekly for more than a year.
Dr. Katrina KnottPost-Doctoral Research Fellow
Academic Background: Ph.D. in Biological Sciences with a concentration in Wildlife
Toxicology, University of Alaska Fairbanks, AK; M.S. in Zoology studying
Nutritional Ecology and Development, University of Alaska Fairbanks, AK; B.A.
in Biology, University of Minnesota Morris, MN.
Conservation interests: reproductive physiology, endocrinology, comparative anatomy and
physiology, ecotoxicology, physiological ecology, nutritional ecology, histomorphology / pathology, wildlife disease
Current research direction/interests: Dr. Knott’s research examines reproductive hormones and pregnancy biomarkers
in mammals for improved knowledge of their reproductive physiology and
conservation. These studies include an evaluation of the reproductive cycles in
giant anteaters and polar bears by non-invasive sampling and detection of hormone metabolites in feces and urine. Dr. Knott is also
helping to monitor the reproductive status of giant panda. This summer, Dr.
Knott will also begin a project comparing reproductive physiology of ursids
including polar bears, giant panda, sloth bears, and Andean bears. The goal of her
research in these species is to increase breeding success and offspring survival
of the captive zoo population. Greater knowledge of the reproductive physiology
of these species will also be applicable to wild populations by providing
information regarding the timing and plasticity of reproductive events for
free-ranging animals and insight into the potential causes of reproductive
failures. Characterization of reproductive events may also aid in the
identification of key time periods when animals are most susceptible to natural
(e.g., climate associated changes in habitat, disease transmission) and
man-made (e.g., industrial development, environmental contaminants)
disturbances that can negatively impact the reproductive physiology and behavior
Beth RobertsResearch Fellow
Academic background: Ph.D.
candidate in Wildlife Biology with concentration in Animal Physiology, Utah
State University; M.S. Animal
Science with concentration in Reproductive Physiology, University of
California, Davis; B.S. in Zoology and Animal Science, The Ohio State
Conservation interests: nutrition
and social behavior effects on reproductive fitness, endocrinology, assisted
reproductive technologies, gamete biology and cryopreservation.
Current research directions/interests:
My past research has focused on efforts to understand physiological
mechanism that interconnect environmental stimulus to the reproductive system
in mammals, using coyotes as a model. I have studied diet effects on the
relationship of reproductive and metabolic hormone fluctuations and embryo
implantation rates; the connection of early postnatal litter hierarchy status
on physical development and sexual maturation; and the correlation of mate
choice behavior to reproductive hormones. At the Memphis Zoo, I am assisting
with reproductive studies of several species including the Giant Panda. Because
these animals have delayed implantation and pseudo-pregnancy, much research has
focused on early determination of pregnancy in pandas. I hope to contribute to
our understanding of Panda pregnancy profiles by looking at unique and new
biomarkers. I am also involved in developing
assisted reproductive technologies (ART) for endangered amphibians,
including work to further develop and improve sperm cryopreservation and
artificial fertilization techniques. Additionally, I will head up a research team to develop sperm
collection, characterization, and storage techniques for large lizard species,
using the Crocodile monitor as a model. Nearly 30% of the known reptile
populations are listed as endangered in the wild and many of the species in
captivity reproduce poorly. We hope to use the work with Crocodile monitor as a foundation for the development
of ART for this species and other endangered reptiles in this family including the
