Bronx Zoo ships 100 rare Kihansi spray toads to Tanzania to help create a new colony

The Kihansi spray toad has vanished from it's native habitat in Tanzania.
The cargo wasn't just precious - it was almost extinct.
An official from the Wildlife Conservation Society's Bronx Zoo flew to Tanzania last week with some seriously exotic carry-on luggage: 100 rare, tiny toads.
The Kihansi spray toad has vanished from its native habitat, and scientists hope to create a new colony by importing some from U.S. zoos.
"It's an amazing feeling," said Jim Breheny, director of the Bronx Zoo.
Last Tuesday, their handler, Alyssa Borek, packed 50 toads from the Bronx Zoo and 50 from the Toledo Zoo into plastic deli containers after swaddling them in paper towels soaked in purified water.
They were loaded into two cardboard boxes that Borek hauled onto a KLM Royal Dutch Airlines jet for the trip from Kennedy Airport to Africa.
She delivered them to a state-of-the-art propagation center. The goal is to eventually move them to the Kihansi Gorge, where the Tanzanian government has installed sprinklers in an attempt to recreate the toads' habitat.
The toads were discovered in 1998, living on less than five acres of a spray zone created by waterfalls in the gorge.
The 2000 opening of a hydroelectric dam, which provides a third of Tanzania's electricity, reduced the flow of the waterfalls, eliminating 90% of the mist.
The toads began to dry out and fall ill. Before they were declared extinct in the wild, scientists collected a colony of them and split them among a handful of zoos.
The Bronx Zoo pumps 1,500 gallons of mist a day to the toads, who are on display in the Reptile House. Food, water and air is carefully purified.
Breheny called it an "incredible commitment" that he and Toledo Zoo officials hope will pay off halfway across the world. "We both have worked very hard for a successful end to the story," he said.

Scientists plan ‘genome zoo’

6 November 2009

An international consortium of scientists plans to collect DNA sequences for 10,000 vertebrate species, approximately one for every vertebrate genus.

Known as the Genome 10K Project, it involves gathering specimens of thousands of animals from zoos, museums, and university collections worldwide, and then sequencing the genome of each species to reveal its complete genetic heritage.

The project was launched in April 2009 and now involves more than 68 scientists, calling themselves the Genome 10K Community of Scientists (G10KCOS). The group outlined its proposal in the Journal of Heredity this month.

According to one of the lead authors, the cost of genome sequencing has been dropping steadily over the past decade, making the sequencing of 10,000 genomes a realistic possibility.

So far, the online database contains samples from more than 16,000 different species of vertebrate animals compiled from more than 50 institutions.

Participants expect the Genome 10K Project to help understand the genetic basis of recent and rapid adaptive changes within vertebrate species and between closely related species. The results can help conservation efforts by enabling scientists to predict how species will respond to climate change, pollution, emerging diseases, and invasive competitors.
