Species: Pallas’ cats (Otocolobus manul)
Status: Near Threatened (IUCN Redlist) in Mongolia due
to poaching, vermin control programs and habitat loss.
• CREW helped to initiate the first comprehensive
ecological study of wild Pallas’ cats in Mongolia to
assess their general health, disease exposure, habitat
and prey needs, and population status.
pallas• CREW scientists have characterized the seasonal
reproductive traits of Mongolian Pallas’ cats and have
cryopreserved semen from wild males to improve genetic
diversity of zoo populations (without removing any cats
from the wild).
• Scientific capacity building in Mongolia has included
training a Mongolian graduate student in reproductive
sciences for research with Pallas’ cats and other native




Species: Brazilian ocelot
(Leopardus pardalis mitis)
brazil_mapStatus: Vulnerable to extinction (IUCN Redlist) in southern
Brazil, primarily due to habitat loss and poaching.
• CREW scientists helped spearhead efforts to establish
the Brazilian Ocelot Consortium, an international
collaboration focused on conserving Brazilian ocelots in
the wild and captivity.
• CREW’s reproductive research with Brazilian ocelots has
resulted in the birth of several healthy kittens from
artificial insemination and embryo transfer using frozen
semen and frozen embryos.
• CREW is applying these proven reproductive
technologies to optimize captive management and
facilitate international exchange of genetic diversity
without transporting live ocelots between countries.
