In The Eyes Of Another: Zoo Academy

Guest blogger: Monneka Johnson, Zoo Academy Senior

My name is Monneka and I am a student at the Zoo Academy. It’s my second year in the program and I had an amazing junior year. I plan to have a successful finish! As a senior, I am not only an example, but I consider myself a leader for the juniors.

Being a Zoo Academy student, my day isn’t just any old crazy day of doing English, math, science, or social studies. The Zoo Academy allows me to explore beyond the average high school day; it’s an ongoing adventure. I have passed several milestones to accomplishing challenges such as handling animals that I’ve never encountered, which gave me a fright at first, but in all, I achieved a personal growth goal. I have had the opportunity to handle multiple species of animals such as the blue-tongued skinks, Brazilian rainbow boas, and armadillos!

We learn how to interact with visitors here at the Zoo, as well as with the staff; between the staff and my peers we’ve become a camaraderie. A “camaraderie” is a trust among friends. We engage what we know, want to know, and how we relate to one another and this is how we build a camaraderie. We show that we take pride in contributing to the Cincinnati Zoo mission statement every day by putting on our uniforms and making sure our tasks get done efficiently and safe.

The Zoo is so engaging. There are no dull moments. We as a team enjoy the character in everyone’s attitude everyday. You’ll almost never be disappointed with an answer; our staff makes the days here at the Cincinnati Zoo interesting from all the informational facts. As a student at the Zoo, being able to learn as you work as well as interact with visitors is an awesome learning experience.

How do you diagnose pregnancy in a lion?

Many visitors to the Zoo have met our two African lions, John and Imani, in the new Africa exhibit. These two young cats were paired up earlier this year with the hope that they would breed and produce their first litter of cubs in the near future. The good news is that breeding activity has been observed on several occasions this past year, and, after at least one pseudopregnancy, it appears that Imani is now pregnant and due to give birth within the next month. Which raises the question – how do you diagnose pregnancy in a lion anyway?

Scientists at the Zoo’s Center for Conservation and Research of Endangered Wildlife (CREW) commonly use three methods for pregnancy diagnosis in wildlife species:  ultrasonography, fecal progesterone analysis, and urine relaxin analysis. Ultrasonography remains the gold standard since visualization of a fetus with a strong heartbeat is the definitive proof of pregnancy. CREW frequently uses abdominal ultrasonography to diagnose and monitor pregnancies in our domestic cats (see below). However, this method can be challenging to apply with a potentially dangerous carnivore, like Imani. Through the Zoo’s operant conditioning program, Imani eventually may be trained to allow voluntary abdominal ultrasound exams, but this method is currently not an option with her.

The second approach for pregnancy diagnosis is the use of fecal progesterone analysis. Lions, like other felids, show an increase in fecal progesterone levels shortly after ovulation that is detectable using CREW’s hormone assays. If lions ovulate but don’t conceive, they will have a pseudopregnancy that lasts 50 to 60 days and then progesterone will decline back to baseline levels. If progesterone concentrations stay elevated beyond 60 days post-breeding, then the female is most likely pregnant. Imani’s fecal hormone profile (below) shows progesterone levels increasing coincident with her last breeding activity and staying elevated through at least 66 days post-breeding (the last fecal sample tested).

The third option for pregnancy diagnosis involves measurement of another hormone, relaxin, that is produced by the placenta and excreted in the urine. CREW has helped to pioneer the use of a bench-top relaxin test for pregnancy diagnosis with urine from cats. Our previous research has found that pregnant domestic cats and Pallas’ cats produce high levels of urinary relaxin that are detectable with the bench-top test, but pregnant cheetahs and clouded leopards apparently do not. Imani is the first lion that we have evaluated late in a suspected pregnancy. Urine samples collected from Imani at day 73 and 74 post-breeding were both positive for relaxin (below, circled line in window #2), providing further presumptive evidence of an ongoing pregnancy. In the absence of a sonogram showing a viable fetus, the positive results from the progesterone and relaxin assays provide our best evidence that Imani is pregnant.

Hopefully, Imani will confirm our diagnosis in the next few weeks with the anticipated birth of her first litter of cubs. Since Imani will be a first-time mom, she will be provided with a quiet, off-exhibit den area to give birth and bond with her cubs, and likely will remain off-exhibit until early spring when the cubs are a bit older.

Bowling for Rhinos was a Smashing Success!

All five living species of rhinos are threatened in the wild due to habitat loss and poaching for their horns, which are worth more than their weight in gold on the black market. Poaching rates have soared sky high, but there are thousands of dedicated, passionate rangers standing in between the rhinos and the poachers – and they need our help.

Each year, the American Association of Zoo Keepers (AAZK) raises funds through Bowling for Rhinos (BFR) events held across North America to support critical rhino conservation projects in the wild. This year, the Greater Cincinnati AAZK Chapter organized its inaugural BFR fundraiser, which took place on October 11 at Stone Lanes.BFR Logo

The turnout was fantastic! More than 160 people registered to bowl and even more showed up just to take part in the festivities. Even J.J. Hoover and Logan Andrusek of the Cincinnati Reds came out to show their support!

Beyond bowling, there were plenty of other opportunities for fun and fundraising. The chapter held a silent auction and raffle and sold t-shirts, chocolate bars and shot glasses, and the bar even offered special rhino-themed drinks. The Zoo’s Sumatran rhino mascot even showed up to meet and greet the bowlers.

In addition to the Zoo and Stone Lanes, the event drew in several other local businesses and individuals as sponsors. A huge thank you goes out to:

  • Mac Paran
  • Riverside Topsoil
  • White Crane Tattoo
  • The Emily and Mark Frolick Foundation
  • Solid Training
  • The Wallace Group Dentistry for Today
  • Nancy Haas
  • Liquid Sasquatch Pottery
  • Listermann Brewery
  • North College Hill Chiropractic Center
  • T.J. Williams Electric Co.
  • Norwood City Schools
  • Gary’s Professional Dog Grooming
  • Mike Dulaney
  • Jeff Mitchell

All in all, the event pulled in more than $8,500! Every penny earned through BFR goes directly to field conservation efforts to protect all five endangered species of rhino. For example, in Indonesia, funds raised support Rhino Protection Units (RPUs) that safeguard Javan and Sumatran rhino populations in national parks. Dedicated wildlife rangers patrol the forests, arresting poachers and destroying snares and traps. And in Kenya, funds raised support the Lewa Conservancy’s Rhino Conservation Programme, which has been extremely successful in protecting black and white rhino populations.

The chapter is quite pleased with how the first annual BFR turned out. Thanks to all who showed their support. We hope you will come out and join us next year!
