Wolf World Item # 121
Category: Ecology & Behavior

Source:
 The American Naturalist, v150 n4 (October 1997) 4 pp.


Abstract:
This study contradicts previous findings that indicate wolf packs smaller than optimal size acquire less food per wolf than those of optimal size. Instead, the data presented indicates that there is less food per wolf as pack size increases. The authors propose a kin-selection hypothesis to explain why wolves live in packs.
