A Frog Love Shack

While humans may need flowers, chocolate, and a candlelit dinner to get in the mood for love, amphibians have quite different requirements. The Bristol Zoo Garden in England has designed what it calls the AmphiPod to encourage frog love. The zoo opened this special “love shack” to breed two endangered frog species—the Lemur Leaf frog and the Golden Mantella.

The mating chambers will provide a safe home for these frogs, which are listed as critically endangered on the IUCN Red List of threatened species.

In this BBC video Amanda Parr takes a look around the new facility with the Bristol Zoo’s Curator of Reptiles, Tim Skelton, giving her tour a Valentine’s Day spin.

As Skelton says of the project:

Until a solution is found to help stop the [chrytid] fungus in the wild, the safekeeping and captive management of threatened amphibians is the only way to ensure their long-term survival.

Our new AmphiPod will allow us to keep frogs in a safe, isolated environment, away from any threat of disease, as well as giving our keepers the opportunity to learn the techniques required for the specialist amphibian care we can provide in the AmphiPod. In future we will be able to provide a safe haven to other amphibian species in immediate danger of extinction.

However, the Zoo is still £30,000 short of the target amount which will help pay for the continued cost of running the facility for the next three years. For a Valentine’s gift with a difference, why not make a donation towards the Zoo’s “love shack”?

What the Frogs Are Telling Us

In 1995, a teacher and her students in southern Minnesota discovered a pond full of frogs with deformities: some frogs with extra legs or eyes missing, others with extra eyes or missing limbs.

A Plague of Frogs by William Souder tells the story of what happened next as these deformed frogs were later found all over Minnesota, and in other parts of the US. The book is both an ecological detective story and a tale of scientific investigation. Were the deformities a natural occurrence or were they caused by toxins in the environment?

Ultimately Souder concludes that ecosystems are so complex and the organisms in them so interconnected that it is difficult for scientists to tease out the exact causes of these malformations. It’s likely, however, that the frogs were physically manifesting the unhealthiness of our environment.

As Souder writes:

So frogs are telling us a lot—so much, perhaps, that we cannot fully understand the message. Frogs are succumbing to parasites, to pesticides, to increases in ultraviolet radiation, to global warming. The earth is changing and the frogs are responding.

This book was written in 2000, before the chrytid fungus that is causing massive die-offs of amphibians became so widespread. I do think it’s worth a read, however, if only to remind us that we have to be careful what chemical and toxins we release into the environment because ultimately we don’t really know what the effects will be on wildlife—and on us. We need to listen to what the frogs are telling us.
