Conservation Evidence: Evidence Data

Collected Evidence: Collected Evidence: Breed mammals in captivity Three studies evaluated the effects of breeding mammals in captivity. One study was across Europe, one was in the USA and one was global. COMMUNITY RESPONSE (0 STUDIES) POPULATION RESPONSE (3 STUDIES) Abundance (1 study): A review of captive-breeding programmes across the world found that the majority of 118 captive-bred mammal populations increased. Reproductive success (2 studies): A review of a captive breeding programme across Europe found that the number of European otters born in captivity tended to increase over 15 years. A study in the USA found that wild-caught Allegheny woodrats bred in captivity. Survival (1 study): A review of a captive breeding programme across Europe found that the number of European otters born in captivity that survived tended to increase over 15 years.

One study was in the USA and one was in Sweden and Norway. COMMUNITY RESPONSE (0 STUDIES) POPULATION RESPONSE (2 STUDIES) Survival (2 studies): A replicated, controlled study in the USA found that most captive coyote pups placed with foster parents were successfully reared. A replicated study in Sweden and Norway found that captive grey wolf pups placed with foster parents had higher survival rates than pups that stayed with their biological mother. Condition (1 study): A replicated study in Sweden and Norway found that captive grey wolf pups placed with foster parents weighed less than pups that stayed with their biological mother.

One study was in the USA, one was in Brazil and one was in China. COMMUNITY RESPONSE (0 STUDIES) POPULATION RESPONSE (3 STUDIES) Reproductive success (3 studies): A study in the USA found that following artificial insemination, fewer than half of female black‐footed ferrets gave birth. A study in Brazil found that following artificial insemination, a captive female Amazonian brown brocket deer gave birth. A replicated study in China found that following artificial insemination, a lower proportion of captive female giant pandas became pregnant than after natural mating.

This study was in Iran. COMMUNITY RESPONSE (0 STUDIES) POPULATION RESPONSE (1 STUDY) Reproductive success (1 study): A controlled study in Iran found that immature eggs of domestic sheep have potential to be used for cloning of Esfahan mouflon.

One study was in Mexico and one was in the USA. COMMUNITY RESPONSE (0 STUDIES) POPULATION RESPONSE (2 STUDIES) Survival (2 studies): A study in Mexico found that a series of non-traditional techniques, combined with natural mating, produced five aoudad embryos that could be cryogenically preserved. A study in USA, found that artificial insemination using preserved genetic material increased genetic diversity and lowered inbreeding in a captive black‐footed ferret population.
