DOI: 10.1016/j.anbehav.2017.05.007
Abstract: The marginal value theorem models patch departure decisions for foraging animals when resources are unevenly distributed. A key component of these models is the decelerating energy gain function used to represent patch depletion. However, the… read more here.

Abstract: Dominance hierarchies structure the adult social networks of many mammals. To identify the conditions that support the establishment of stable hierarchical relationships within groups of familiar rivals, we explored the ontogeny of spatial, social and… read more here.

DOI: 10.1093/conphys/coad034
Abstract: Abstract Evaluating consequences of stressors on vital rates in marine mammals is of considerable interest to scientific and regulatory bodies. Many of these species face numerous anthropogenic and environmental disturbances. Despite its importance as a… read more here.

DOI: 10.1098/rspb.2021.1258
Abstract: All organisms face resource limitations that will ultimately restrict population growth, but the controlling mechanisms vary across ecosystems, taxa, and reproductive strategies. Using four decades of data, we examine how variation in the environment and… read more here.

DOI: 10.1152/physiol.2023.38.s1.5794987
Abstract: Marine mammals face increased human activities in the ocean, including shipping, recreation, and seismic exploration. Such disturbances may alter short-term behavior and long-term life history patterns; however, many of the mechanistic details of responses remain… read more here.

DOI: 10.1177/1040638720907100
Abstract: In February 2015, we conducted a field study of causes of mortality of northern elephant seal (Mirounga angustirostris) pups on San Miguel Island, California. Autopsies were performed on 18 freshly dead pups. Ages of pups… read more here.
