There are so few wild ocelots in the US that the cats are becoming inbred, with a bad prognosis for their ultimate survival. But researchers are perfecting ways to get new genes into the population.
Presenting accounts of technological success in captive lion breeding against the backdrop of rapidly diminishing wildlife loss lets humans off the hook too easily.
The Tonquin and Brazeau caribou herds in Jasper National Park are now so small that they cannot recover on their own.
Canada needs a national board of advisers to hold Parks Canada’s feet to the fire and shield it from political interference.
Breeding in captivity is expensive, and means the animal’s gene pool will be sorely depleted. Using sperm and egg freezing and IVF techniques can reduce that.
Many breeders say they’re stewards of conservation, but no captive tiger has ever been released into the wild.

The slaughtered tigers were not bred in zoos, yet their story should put captive breeding in general into question.
If we want any future for wild populations of the numerous species traded for pets, exhibits and use in medicines, drastic action is needed to control their international and domestic trade.

Some animals bred in captivity often lack the skills needed to survive in the wild. But the Tasmanian devil is showing it’s a natural born killer.
The program can work well for polygamous species such as gorillas.

Computer dating for animals? Finding the right matchup - using DNA rather than personality questionnaires - could help select the best partnerships for captive breeding programs.
Pandas breed in the wild after fighting off competition from other males – something they’re denied in captivity.
Zoos provide succor for species having a tough time of it in the wild.

Today, many zoos promote the protection of biodiversity as a significant part of their mission. As conservation “arks” for endangered species and, increasingly, as leaders in field conservation projects…
