RESUMO
Red pandas, Ailurus fulgens, are popular exhibit animals in zoos. It is clear from data in the global studbook that there is considerable variation in their breeding success in different zoos. Population managers have long suspected that environmental temperature plays a key role in these differences. It is generally thought that this species, which is so well adapted to life in the cold damp climate of the mid-altitude forests of the Himalayas, has a problem coping with warmer climates. However, this hypothesis has not been tested until now. Using data extracted from the global studbook, we have demonstrated that climate at the location of birth has a clear impact on the survival of infant red pandas.

The lion has historically probably been widespread at low densities in West and Central Africa, nowadays they are largely restricted to small isolated populations inside protected areas. The total number is probably between 1200 and 2700, the best possible guesstimate would be 1700. Mankind is the main cause for the suspected decline of lion populations, both inside and outside protected areas. Very little research has been done on West and Central African lions a few examples are summarized here. The international community is slowly becoming aware of threats to lions in the region and some initiatives for lion conservation have started.
