Mountain lion (Puma concolor) depredation incidents on livestock herds were recorded at 15 ranches in southern Brazil from 1993 to 1995. Maximum losses to mountain lions were 78% for goats, 84% for sheep, and 16% for cattle. Cattle mortality arising from causes other than depredation assumed a greater importance in herd productivity. In contrast, a...
The puma (Puma concolor, Carnivora: Felidae), extinct from considerable extensions of its former distribution, is considered threatened in south, southeast and northeast Brazil. Areas in the south and southeast have only recently been recolonized by the species, following decrease in logging activities after depletion of the Atlantic rainforest in...

Information on martial arts may often be mislead by beliefs rather than guided by knowledge. It is not all about fighting nor it is all about misticism. This book links Tai Chi's philosophical approach with both well being, emotional inteligence and martial application (self defense).
