“…They also contend that the empirical evidence supporting the RPS is weak. This point is also made by Kacelnik and Krebs (1985) who cast doubt on Milinski (1984) and Regelmann's (1984) application of the RPS in their analysis of stickleback behaviour.…”

“…Some individual-based simulations have predicted a decrease in patch switching (Regelmann 1984;Bernstein et al 1991;Cezilly and Boy 1991). Kennedy and Gray (1993) and Morris (1987) analytically predicted that with greater travel costs there would be greater skewing of the distribution toward richer patches than the IFD would predict, as individuals would be attracted unidirectionally toward the richer patches.…”

“…The IFD has seen success in describing habitat selection (Lin and Batzli 2001;Pusenius and Schmidt 2002) and the distributions of foraging animals in the field (e.g., Harper 1982;Oksanen et al 1995;Jones et al 2006) and in laboratory experiments (e.g. , Milinski 1979;Regelmann 1984;Korona 1990). The IFD corresponds to an evolutionarily stable strategy (ESS; a strategy that if adopted by a population prevents invasion by another population that is initially rare and uses a different strategy; e.g., Cressman et al 2004;Cantrell et al 2007; Křivan et al 2008), for which at steady state no individual can improve fitness by moving to another patch.…”

Online enhancements: appendixes.abstract: A key assumption of the ideal free distribution (IFD) is that there are no costs in moving between habitat patches. However, because many populations exhibit more or less continuous population movement between patches and traveling cost is a frequent factor, it is important to determine the effects of costs on expected population movement patterns and spatial distributions. We consider a food chain (tritrophic or bitrophic) in which one species moves between patches, with energy cost or mortality risk in movement.In the two-patch case, assuming forced movement in one direction, an evolutionarily stable strategy requires bidirectional movement, even if costs during movement are high. In the N-patch case, assuming that at least one patch is linked bidirectionally to all other patches, optimal movement rates can lead to source-sink dynamics where patches with negative growth rates are maintained by other patches with positive growth rates. As well, dispersal between patches is not balanced (even in the two-patch case), leading to a deviation from the IFD. Our results indicate that cost-associated forced movement can have important consequences for spatial metapopulation dynamics. Relevance to marine reserve design and the study of stream communities subject to drift is discussed.

“…Although the studies generally support ideal free models, quantitative discrepancies between predictions and observations are common. The mechanisms invoked to account for these discrepancies, such as asymmetries in priority of access to a point food source (Harper 1982), the need for individuals to sample alternative resource clumps (Milinski 1984) and the switching between clumps that ensues (Regelmann 1984) easily apply at small spatial scales but are unlikely to account for discrepancies at large spatial scales such as choice of breeding habitats (Stamps 2001;Shochat et al 2002). The behavioural mechanisms that could account for such large-scale discrepancies remain relatively unexplored because studies conducted at large spatial scales, generally, ignore behaviour altogether and focus instead on broad environmental correlates of animal distributions.…”

Inadvertent social information in breeding site selection of natal dispersing birds

Several species use the number of young produced as public information (PI) to assess breeding site quality. PI is inaccessible for synchronously breeding birds because nests are empty by the time the young can collect this information. We investigate if location cues are the next best source of inadvertent social information (ISI) used by young prospectors during breeding site choice. We experimentally deployed ISI as decoys and song playbacks of breeding males in suitable and sub-optimal habitats during pre-and postbreeding periods, and monitored territory establishment during the subsequent breeding season for a social, bobolink (Dolichonyx oryzivorus), and a more solitary species, Nelson's sharp-tailed sparrow (Ammodramus nelsoni ). The sparrows did not respond to treatments, but bobolinks responded strongly to post-breeding location cues, irrespective of habitat quality. The following year, 17/20 sub-optimal plots to which bobolink males were recruited were defended for at least two weeks, indicating that song heard the previous year could exert a 'carry-over attraction' effect on conspecifics the following year. Sixteen recruited males were natal dispersers, as expected when animals have little opportunity to directly sample their natal habitat quality. We suggest that differences in breeding synchronicity may induce an equivalent clinal distribution of ISI use.
