Resident and dispersal behavior among individuals within a population of American lobster Homarus americanus

摘要: Various biases and limitations associated with mark-recapture research have resulted in conflicting interpretations of individual movement patterns, rendering unclear the selective pressures that could be responsible for structuring populations influencing behavior patterns marine environment. To address these issues, novel modeling techniques developed mammalian systems were applied to trajectory data from an American lobster Homarus americanus population order describe quantitatively seasonal patterns. Basing individual- population-level analyses on a correlated random walk model, individuals found belong 1 2 types: residents or dispersers. Over course year, resident animals remained general area their release, whereas dispersing moved rapidly away release sites autumn slowly returned spring. Such can explained as responses hard-substrate habitat. The effect distribution structure lobsters significant consequences sustainable exploitation species.
