“…In combination with certain values for the correlation degree, the bias resulted in a looping search strategy where individuals moved in small circles. Such a type of movement has been observed for a variety of animals (Hoffmann, 1983;Bell, 1985;Mu¨ller and Wehner, 1994;Durier and Rivault, 1999;Conradt et al, 2000;Bengtsson et al, 2004;Wiktorsson et al, 2004). If a simple rule such as a bias in a correlated random walk can emulate apparent systematic search strategies such as a looping strategy, we might expect to observe such systematic search strategies more frequently in nature -even for organisms with rather poor perceptive or orientation abilities.…”

The search strategies dispersers employ to search for new habitat patches affect individuals' search success and subsequently landscape connectivity and metapopulation viability. Some evidence indicates that individuals within the same species may display a variety of behavioural patch searching strategies rather than one species-specific strategy. This may result from landscape heterogeneity. We modelled the evolution of individual patch searching strategies in different landscapes. Specifically, we analysed whether evolution can favour different, co-existing, behavioural search strategies within one population and to what extent this coexistence of multiple strategies was dependent on landscape configuration. Using an individual-based simulation model, we studied the evolution of patch searching strategies in three different landscape configurations: uniform, random and clumped. We found that landscape configuration strongly influenced the evolved search strategy. In uniform landscapes, one fixed search strategy evolved for the entire spatially structured population, while in random and clumped landscapes, a set of different search strategies emerged. The coexistence of several search strategies also strongly depended on the dispersal mortality. We show that our result can affect landscape connectivity and metapopulation dynamics.

“…In addition, foray search has at least two further important advantages, namely, that foray dispersers regularly return to their starting habitat patch and that the shape of the search pattern can be fine-tuned through evolution to a particular landscape. The first property enables foray dispersers to reorient themselves periodically (Mueller and Wehner 1994;Durier and Rivault 1999) and to postpone or abandon futile dispersal attempts (Christian 1993;Conradt et al 2000). It also enables them to replenish resources ) so that they need only to carry with them smaller, predeterminable quantities of resources during dispersal.…”

“…1). The same type of search strategy (which we will term "foray search") has been reported in many other animals, including other insects (Wehner and Srinivasan 1981;Hoffmann 1983;Mueller and Wehner 1994;Durier and Rivault 1999;A. Seymour, personal communication: Plebejus argus), mammals (Wiggett et al 1989;Christian 1993;Sun 1997;E.…”

In the absence of evidence to the contrary, population models generally assume that the dispersal trajectories of animals are random, but systematic dispersal could be more efficient at detecting new habitat and may therefore constitute a more realistic assumption. Here, we investigate, by means of simulations, the properties of a potentially widespread systematic dispersal strategy termed "foray search." Foray search was more efficient in detecting suitable habitat than was random dispersal in most landscapes and was less subject to energetic constraints. However, it also resulted in considerably shorter net dispersed distances and higher mortality per net dispersed distance than did random dispersal, and it would therefore be likely to lead to lower dispersal rates toward the margins of population networks. Consequently, the use of foray search by dispersers could crucially affect the extinction-colonization balance of metapopulations and the evolution of dispersal rates. We conclude that population models need to take the dispersal trajectories of individuals into account in order to make reliable predictions.

In other walking insects, a vision-independent odometer is used by nocturnal cockroaches (Durier and Rivault 1999) and bumblebees estimating distances in naturally dark situations, such as in the nest (Chittka et al 1999). In the present laboratory work, we investigated whether or not Cataglyphis cursor ants can use their odometer even in complete darkness.…”

In contrast to flying insects, in which distance estimation is visually mediated, self-induced image motion and use of familiar landmarks are known to play a minor role in ants. Here we show that strictly diurnal Cataglyphis cursor ants can gauge with accuracy the distance they have travelled even in complete darkness in the absence of any other cues, i.e. chemical or protocounting information. Thus, an ant's odometer is a vision-independent system based on proprioceptive cues, implicating some form of step counting, which remain to be elucidated.
