The American Naturalist, 1976
Models are proposed which examine emigration thresholds from resource patches encountered within a given search strategy. With one patch type and no competition during utilization, there is a single optimal investment duration (Iopt) which depends on the gain accumulated during investment in the patch, G(I), and on the mean search cost between patches.

To test several hypotheses concerning the optimal life-history characteristics expected to be associated with individuals encountering primarily high or low population density, we scored flying behavior, development time, fecundity, and competitive ability in two populations of flour beetles (Tribolium castaneum) differentiated with respect to ...

An investigation was carried out on 28 Misaki young female feral horses living in Misaki Island, Japan to explore the behavioral patterns, and proximate causes of emigration of these females when they left their natal band or mothers. All young females emigrated between 1 and 4 years of age.

AbstractTerrestrial hermit crabs in the family Coenobitidae (genera Coenobita and Birgus) must migrate onto land after completing a pelagic larval stage in the ocean. Better knowledge of emigration behavior would assist in the conservation and management of coenobitid populations by helping identify and protect the habitats they need to complete their ...

I examined the vigilance behavior of male Cebus capucinus residing in four groups in Santa Rosa Park, Costa Rica. One male emigrated from each of three study groups, providing ideal experimental conditions for examining the effect of coresident males on male vigilance behavior (social and non-social).
