Male black rhinoceros “Faru,” which is short for Kifaru (the Swahili name for rhino), arrived at the Cincinnati Zoo on July 21, 2015.
Faru and Seyia – A Match Made…by the SSP!
The 2,800 pound rhino was brought to the Cincinnati Zoo from Zoo Atlanta on a breeding recommendation from the Association of Zoo and Aquarium’s (AZA) Species Survival Plan (SSP). The SSP has determined that Faru and the Cincinnati Zoo’s female black rhino, “Seyia,” are a good genetic match. So, if all goes well, there could be rhino calves in the Zoo’s future!
Keepers have spent the past several months getting to know Faru and his behavioral patterns. He will spend 2 to 6 weeks settling in, learning behaviors, and getting to know the Cincinnati Zoo animal care staff before being introduced to visitors.
“There is frequent communication between keepers before the rhinoceros is transferred. We really try to learn their behavioral patterns and habits so we can best accommodate them once they’ve arrived. The transfer process is incredibly involved,” said head keeper Randy Pairan.
Keeper Marjorie Barthel says, “He is doing well. We are taking things very slowly with him to allow him to move forward with the least amount of stress possible. He has come so far already in his new home. Right now I’m working on building a relationship with him. We need to trust each other.”
Faru was born at the San Antonio Zoological Gardens & Aquarium in 2004. He moved to Atlanta in April 2011 where he bred one calf. Because black rhinos are solitary animals, Faru will stay separated from Seyia until late fall. They will be put together when they are familiar with each other and ready to breed. Introductions are going well.
Faru’s Journey to Cincinnati
So how exactly do you move a large rhino from Atlanta to Cincinnati? Follow Faru’s journey in the images below to find out!
About Black Rhinos
The black rhinoceros (Diceros bicornis) is native to the eastern and central areas of Africa, including Kenya, Tanzania, and Zimbabwe. They eat mostly leafy plants, branches, shoots, thorny wood bushes, and fruit. Black rhinos also have two large horns made of keratin that they use for defense, intimidation, and feeding. An adult can weigh anywhere between 1,760 and 3,080 pounds, and newborns (calves) weigh between 35 and 55 pounds. Black rhinos breed year-round and have a gestation period that lasts 15 months. They are one of the oldest known species of mammals.
Faru’s species is critically endangered with more than 115 individuals being managed by the SSP. As recently as 1970, an estimated 65,000 black rhinos could be found throughout sub-Saharan Africa. However, between 1970 and 1992, 96-percent of Africa’s remaining black rhinos were killed in a wave of poaching due to the value of their horns. Heightened conservation efforts following the poaching increase led the black rhino population to grow from 2,410 in 1995 to a current total of 4,848. Today, black rhinos live in protected parks located in Zimbabwe, South Africa, Kenya, Namibia, and Tanzania. Poaching is still a serious problem, threatening to wipe out decades of conservation efforts. Even protected parks experience poaching breeches, which means the amount of safe land available to black rhinos is diminishing.
The Cincinnati Zoo’s Carl H. Lindner Jr. Family Center for Conservation and Research of Endangered Wildlife (CREW) will be doing reproductive research on Faru and Seyia as part of the continued efforts to save the black rhinos. All five species of rhinoceros—White, Black, Greater One-Horned (aka Indian), Sumatran, and Javan—are perilously close to extinction in the wild.

Florida has more fern species than any other state in the mainland United States, and CREW is working with partners at Fairchild Tropical Botanic Garden in Miami, Florida, to help propagate several of the most endangered from rapid urbanization and habitat loss.
The gridscale maiden fern, Thelypteris patens, is a large, beautiful fern that can reach over five feet in height. The patens variety is known only from the pine rockland habitat in Miami-Dade County and is listed as endangered in Florida. The population in one particular preserve declined to a single plant, which died in 2013.
However, before it died, researchers from Fairchild Tropical Botanic Garden collected spores from that plant and sent them to CREW’s Plant Lab here at the Cincinnati Zoo & Botanical Garden. CREW plant scientists germinated the spores in test tubes (in vitro) to produce tiny gametophytes, which represent the first stage in the fern life cycle.
These were then nurtured further in culture to produce sporophytes, which represent the second stage of fern growth and are the plants we normally think of as ferns. The sporophytes were acclimatized to soil at CREW, and then over 200 of these plants were sent to collaborators at Fairchild Tropical Botanic Garden where they were grown further in their greenhouses.
Finally, in May and June of last year, over 150 of the ferns propagated at CREW were outplanted back into the preserve where the species had been extirpated.
The plants are being monitored by Fairchild Tropical Botanic Garden. As of February 2015, the plants have had an 89% survival rate.

Welcoming Two New Post-Doctoral Fellows
Two new post-doctoral fellows, Dr. Lindsey Vansandt and Dr. Anne-Catherine Vanhove, were welcomed to CREW in the fall of 2014.
With funding support from the Joanie Bernard Foundation, Dr. Vansandt will be working with Dr. Bill Swanson, CREW’s Director of Animal Research. Dr. Vansandt obtained her Doctor of Veterinary Medicine degree from the University of Missouri and her Doctor of Philosophy degree from the University of Maryland (in collaboration with the Smithsonian Conservation Biology Institute). Her Ph.D. studies focused on characterization and propagation of spermatogonial stem cells in domestic cats as a model for conserving endangered cat species. Dr. Vansandt also has experience working in veterinary emergency services. At CREW, she will be conducting studies to improve the health and welfare of feral and shelter cats as well as helping to apply oviductal AI for propagation of endangered felids.
With funding from the Institute of Museum and Library Services (IMLS), Dr. Vanhove will be evaluating survival of plant samples in CREW’s Frozen Garden under the supervision of Dr. Valerie Pence, Director of Plant Research. Dr. Vanhove will complete the second phase of the IMLS project, focusing primarily on the survival of shoot tips and gametophytes after long-term storage in liquid nitrogen. She recently received her Ph.D. from the Division of Crop Biotechnics, Katholieke Universiteit Leuven, in Leuven, Belgium. Her thesis work with meristem culture, stress physiology, and cryopreservation makes her well suited for the IMLS project.
The University of Cincinnati/Cincinnati Zoo Connection
CREW has had a long-standing collaborative relationship with the University of Cincinnati’s (UC) Department of Biological Sciences, but today it is strengthened by two promising young scientists who split their time between CREW and UC. Corrina DeLorenzo and Megan Philpott are both enrolled in UC’s Ph.D. program under Drs. Ken Petren and Theresa Culley, respectively, but they are conducting much of their dissertation research at CREW.
Corrina earned her bachelor’s degree at Miami University, with a double major in Zoology and Environmental Science. As an undergraduate, she became involved in research evaluating the population genetics of the Italian wall lizard or “Lazarus lizard” in the Cincinnati area. After graduating, Corrina was accepted to CREW’s summer internship program, working with Dr. Erin Curry on the Polar Bear Signature Project. She was recruited into UC’s graduate program in January 2014. Since starting her Ph.D. research, Corrina has identified multiple antibodies that detect specific proteins in polar bear feces in an effort to develop a polar bear pregnancy test.
Megan received her bachelor’s degree from UC in Biology and was also an intern at the Cincinnati Museum Center, managing the Museum’s Philippine Bird Genetics project. Her Ph.D. research is part of the Plant Lab’s IMLS funded project to evaluate samples that have been stored for years in CREW’s CryoBioBank for genetic changes that might have occurred over time. In April, Megan was awarded the Botanical Society of America’s Public Policy award to attend Congressional Visits Day on Capitol Hill. There, she learned about communicating science to policy makers and met with the offices of Ohio Senators and Representatives to request their support for increased federal funding of scientific research, using CREW’s research as an example of the importance of federal funding and support.

P&G Wildlife Conservation Scholars
In 2011, CREW established a partnership with the Ohio State University’s College of Veterinary Medicine to train veterinary students in conservation sciences with funding support from Procter & Gamble Pet Care. This past summer, two OSU veterinary students, Kelly Vollman and JaCi Johnson, were selected as P&G Wildlife Conservation Scholars.
Kelly worked with Dr. Monica Stoops analyzing urinary testosterone and glucocorticoid concentrations to determine if the pattern of excretion could be used to predict gender, parturition date and assess fetal viability during Indian rhino gestation. Kelly analyzed urine samples collected throughout seven Indian rhino pregnancies that resulted in three male and four female calves. Six of the pregnancies ended with the birth of live calves, whereas one pregnancy ended in a stillbirth, a relatively common occurrence in this rhino species. By learning more about the endocrinology of pregnancy, results from Kelly’s study will help establish physiological markers to improve pregnancy outcome in this species.
JaCi worked with Dr. Bill Swanson to investigate cat sperm vitrification as an alternative to standard slow freezing methods. Vitrification involves ultra-rapid cooling to avoid ice crystal formation and form a “glass” instead. For this study, JaCi collected semen from domestic cats (and one ocelot) and compared vitrification in a sucrose solution, with direct pelleting in liquid nitrogen, to slow freezing with glycerol in straws over liquid nitrogen vapor. Post-thaw sperm motility and acrosome status were similar between methods and 25% of domestic cat oocytes were fertilized following insemination with vitrified
sperm. This simplified approach to cat semen preservation may be particularly useful for field biologists working with felids in the wild.
