Wolf pack size and food acquisition

Article Abstract:

The predation rates of gray wolves were analyzed to understand why wolves live in packs as well as to determine the relationship between wolf pack size and food acquisition. Results reveal that wolves live in packs so that adults pairs can efficiently feed their offsprings with surplus food. Results further suggest that there is a very weak relationship between increase in pack size and food acquired per wolf. A large wolf pack does not necessarily acquire more food.

Nest predation among vegetation layers and habitat types: revising the dogmas

Article Abstract:

Nest predation rates of ground-nesting birds are lower than that of off-ground nesting birds in the case of forest habitats. Nesting mortality appears to be greater in shrub and grassland habitats. Nest predation rates are believed to be higher in ground nesting species than off-ground nesting species. Studies in Arizona and Arkansas forests suggest that such a conclusion is not applicable to forest habitat.
