This note is intended to propose a correction in the report of the first occurrence of natural infection of Leishmania (Viannia) in this species. We and the other scientific groups reinforced that Tr. auraensis is a possible vector involved in th...

The relationship between energy intake and metabolic requirements of beavers {Castor canadensis) is discussed in regard to the spatial requirements of three colonies. A 26pound yearling beaver requires 850 kcal of digestible energy, or 1.5 lb of fresh aspen per day, to maintain its daily metabolic processes with no additional growth. In order for such a beaver to attain maximum growth, 2040 kca...
