Allocare in St. Lawrence estuary belugas: patterns, prospective drivers, and potential benefits
Allocare, care provided to offspring by non-parents, challenges our understanding of how animals should allocate their time and energy. The evolution and maintenance of allocare in populations suggests that alloparents receive fitness benefits from allocare. In many species, recipient offspring also...

Allocare, care provided to offspring by non-parents, challenges our understanding of how animals should allocate their time and energy. The evolution and maintenance of allocare in populations suggests that alloparents receive fitness benefits from allocare. In many species, recipient offspring also receive important benefits from alloparents. My research represents the first in-depth investigation of allocare in wild belugas. By examining patterns of allocare, I seek to understand why beluga allomothers provide care to the offspring of others. My findings suggest that allocare in St. Lawrence Estuary belugas may be driven by kin selection and reciprocation.
