“…Consequently, individuals could use public information for assessing quality of patches and selecting future breeding habitats (Doligez et al 2003a). Such a strategy of breeding habitat selection requires that individuals prospect different habitat patches to gather cues of conspecific reproductive performance.…”

Because habitat quality strongly affects individual fitness, understanding individual habitat selection strategies is fundamental for most aspects of the evolution and conservation of species. Several studies suggest that individuals gather public information, i.e. information derived from the reproductive performance of conspecifics, to assess and select habitats. However, the behavioural mechanisms of information gathering, i.e. prospecting, are largely unknown, despite the fact that they directly constrain individual selection strategies. To test whether prospectors gather public information or other cues of habitat quality, we manipulated brood size of collared flycatchers (Ficedula albicollis) and investigated subsequent attraction of prospectors. Experimentally adding two nestlings increased the probability of attracting prospectors to the nest as a result of increased parental feeding rates. Prospectors were attracted to the most successful sites because feeding rate predicted subsequent fledgling production. In the year following prospecting, individuals selected a breeding site very close to the prospected site. These results provide the first experimental evidence, to our knowledge, of the links between information gathering behaviour and breeding habitat selection strategies based on public information.

“…This has been predicted to be important in shaping the optimal dispersal rate (Venable & Brown, 1988 ;Cohen & Levin, 1991;Travis, 2001) and also for the selection of condition-dependent dispersal strategies. When there is some autocorrelation, future environmental conditions can be predicted on the basis of the current conditions, and so condition-dependent dispersal may evolve, with dispersal cueing on the environmental parameters correlating with patch quality (Scheiner, 1993;Danchin, Heg & Doligez, 2001 ;Doligez et al, 2003).…”

“…For instance, dispersal dependent on environmental factors such as food availability is indicative of the importance of variation in intrinsic patch quality for the evolution of dispersal. The majority of evolutionary and population models typically treat dispersal as a fixed, unconditional strategy (for exceptions see Tables 1 and 2) though fixed strategies, insensitive to the environment, may only be expected when there are constraints on obtaining information on patch quality or when changes in habitat quality are unpredictable (Scheiner, 1993;Doligez et al, 2003).…”

“…In their study, movement out of a patch was greater when the population density was low and more variable due to demographic stochasticity, both characteristics of small patches. Patch size is likely to be a phenomenological description of patch carrying capacity, which has Doligez et al (2003) also been predicted to be negatively correlated with dispersal rate (McPeek & Holt, 1992 ;Doncaster et al, 1997). Covariation between patch size, population size and average degree of relatedness introduces further confounding variables.…”

Causes and consequences of animal dispersal strategies: relating individual behaviour to spatial dynamics

Knowledge of the ecological and evolutionary causes of dispersal can be crucial in understanding the behaviour of spatially structured populations, and predicting how species respond to environmental change. Despite the focus of much theoretical research, simplistic assumptions regarding the dispersal process are still made. Dispersal is usually regarded as an unconditional process although in many cases fitness gains of dispersal are dependent on environmental factors and individual state. Condition-dependent dispersal strategies will often be superior to unconditional, fixed strategies. In addition, dispersal is often collapsed into a single parameter, despite it being a process composed of three interdependent stages : emigration, inter-patch movement and immigration, each of which may display different condition dependencies. Empirical studies have investigated correlates of these stages, emigration in particular, providing evidence for the prevalence of conditional dispersal strategies. Ill-defined use of the term ' dispersal', for movement across many different spatial scales, further hinders making general conclusions and relating movement correlates to consequences at the population level. Logistical difficulties preclude a detailed study of dispersal for many species, however incorporating unrealistic dispersal assumptions in spatial population models may yield inaccurate and costly predictions. Further studies are necessary to explore the importance of incorporating specific condition-dependent dispersal strategies for evolutionary and population dynamic predictions.

“…Increased foraging is likely through reduced vigilance (Ims, 1990;Roberts, 1996;Childress & Lung, 2003;Mooring et al, 2004) and through information from conspecifics' foraging. The cues that conspecifics learn from their neighbours about reproductive success, predators, and resources is termed 'public information' (Danchin et al, 1998;Doligez et al, 2003;2004;Donahue, 2006;Boulinier et al, 2008).…”

Calving grounds of migratory tundra caribou (Rangifer tarandus) have two prominent characteristics. Firstly, the cows are gregarious, and secondly, the annual calving grounds spatially overlap in consecutive years (spatial fidelity). The location of consecutive annual calving grounds can gradually shift (either rotationally or un-directional) or more rarely, abruptly (non-overlapping). We propose a mechanism to interpret and predict changes in spatial fidelity. We propose that fidelity is linked to gregariousness with its advantages for individual fitness (positive density-dependence). Our argument is based on a curvilinear relationship between the density of cows on the calving ground (which we use to index gregariousness) and spatial fidelity. Extremely high or low densities are two different mechanisms which can lead to reduced spatial fidelity to annual calving grounds and reflect the caribou's adaptive use of its calving ranges.
