Dr. Ruth of Detroit Zoo fosters amorous amphibians
ROYAL OAK, Michigan — Dr. Ruth is bringing her sex-pertise to the Detroit Zoo.
Not to be confused with famed human sex therapist Dr. Ruth Westheimer, Dr. Ruth Marcec is the new director of the zoo’s National Amphibian Conservation Center. She is tasked with inducing frogs and salamanders to make a love connection — something the little critters aren’t doing enough of these days.
Experts estimate that about half of the world’s 7,600 known species of amphibians is threatened.
“It’s very much a crisis,” said Marcec. “If you combine all the endangered mammals and birds, that still doesn’t add up to the percentage of amphibians that are threatened and endangered.”
Among her responsibilities, which include overseeing amphibian care and welfare as well as conservation and research programs, Marcec is tasked with encouraging the cold-blooded vertebrates in her care to get down.
“Amphibians are very difficult to breed in captivity,” she said. “They need specific barometric pressure. They need specific rainfall. Things like that.”
A veterinarian and reproductive physiologist, Marcec has developed a grading scale for amphibian ultrasound procedures used at zoos and aquariums across the globe, and she travels to other institutions to assist with their amphibian breeding efforts. The 30-year-old is a frequent visitor to Henry Doorly Zoo in Omaha, Nebraska, where she breeds bluespotted salamanders and Mississippi gopher frogs.
All of these efforts to keep amphibian species going are being undertaken for good reason, Marcec said.
“If we didn’t have amphibians, a lot of our ecosystems just wouldn’t exist.”
