Hamilton's rule confronts ideal free habitat selection

Hamilton's rule confronts ideal free habitat selection.

If individuals occupy habitats in a way that maximizes their fitness, if they are free to occupy the habitats they choose and if fitness declines with population density, then their abundance across habitats should follow an ideal free distribution. But, if individuals are genetically related, this simple fitness-maximization mechanism breaks down. Habitat occupation should obey Hamilton's rule...

Dispersal among habitats varying in fitness: reciprocating migration through ideal habitat selection

Seasonal Moose Habitat Selection

The moose is Minnesota’s largest wild animal. In December 2012 moose were proposed as a species of special concern under Minnesota law due to their population decline (Baker, 2012). Time series analysis of the northeast Minnesota moose population estimates conducted by Lenarz (2012) found a significant decline between 2005 and 2012. Moose habitat lacks highly specific requirements, depending mo...

Habitat selection in whiting

Given a choice of habitats in a laboratory experiment, whiting Merlangius merlangus preferentially spent most time over sand, then gravel and least time over a habitat with emergent structures. The introduction of a predator stimulus increased the preference for the sand habitat for large whiting, whereas small whiting had an increased preference for the habitat with emergent structures. # 2004...

Modeling rule-based behavior: habitat selection and the growth-survival trade-off in larval cod

Environmental variation can cause significant fluctuations in the survival of larval fish and plankton. Understanding these fluctuations is critical for developing more accurate fisheries models, which are needed for both scientific and socioeconomic research. Growth, survival, and dispersal of marine planktonic larvae rely strongly on their behavior. Larval fish change their vertical positioni...
