“…McPeek & Holt, 1992). The structure of environmental variation also matters: increasing spatial autocorrelation selects for increased dispersal propensity (although see Fronhofer et al, 2014), while increasing temporal autocorrelation selects for a reduced dispersal propensity (e.g. Travis, 2001).…”

“…Modern approaches to modelling dispersal evolution typically allow the costs and benefits of the departure, transfer, and settlement stages to interact and co-evolve, which then influences trade-offs with other aspects of life history (e.g. Travis et al, 2012;Fronhofer et al, 2014). These models show how direct selection for dispersal in one stage can result in evolutionary changes in other stages, including settlement, both directly and indirectly (Stamps, Krishnan & Reid, 2005;Burton, Phillips & Travis, 2010).…”

“…For example, allelic variation in a gene underlying larval foraging in fruit flies (Drosophila melanogaster ) also relates to dispersal distances (Edelsparre et al, 2014). Selection for movement indirectly related to dispersal, such as foraging or exploration, might not only increase displacement distances during the transfer stage, but also influence selection on traits influencing the departure and settlement stages of dispersal (Stamps et al, 2005;Benard & McCauley, 2008;Mabry & Stamps, 2008Bonte, Hovestadt & Poethke, 2010Travis et al, 2012;Fronhofer et al, 2014). As with plants, many traits that influence dispersal in animals are clearly linked to fitness through the benefits brought about by dispersal (i.e.…”

When is dispersal for dispersal? Unifying marine and terrestrial perspectives

Recent syntheses on the evolutionary causes of dispersal have focused on dispersal as a direct adaptation, but many traits that influence dispersal have other functions, raising the question: when is dispersal 'for' dispersal? We review and critically evaluate the ecological causes of selection on traits that give rise to dispersal in marine and terrestrial organisms. In the sea, passive dispersal is relatively easy and specific morphological, behavioural, and physiological adaptations for dispersal are rare. Instead, there may often be selection to limit dispersal. On land, dispersal is relatively difficult without specific adaptations, which are relatively common. Although selection for dispersal is expected in both systems and traits leading to dispersal are often linked to fitness, systems may differ in the extent to which dispersal in nature arises from direct selection for dispersal or as a by-product of selection on traits with other functions. Our analysis highlights incompleteness of theories that assume a simple and direct relationship between dispersal and fitness, not just insofar as they ignore a vast array of taxa in the marine realm, but also because they may be missing critically important effects of traits influencing dispersal in all realms.

“…Of course, in purely winddispersed plants with monomorphic seeds such as modelled by Travis et al (2010) trade-offs may also occur between plant height which influences dispersal distance and seed production. Such tradeoffs may then lead to the evolution of different plant heights depending on habitat availability or local extinctions, for example (for the effect of local extinctions on the evolution of dispersal kernels see Fronhofer et al, 2014).…”

1As much dispersal research has focused on the eco-evolutionary dynamics of dispersal rates, it remains 2 unclear what shape evolutionarily stable dispersal kernels must be expected to have. Yet, detailed 3 knowledge about dispersal kernels, quantifying the statistical distribution of dispersal distances, is of 4 pivotal importance for understanding biogeographic diversity, predicting species invasions, and explaining 5 range shifts. We therefore examine the evolution of dispersal kernels in an individual-based model of a 6 population of sessile organisms, such as trees or corals. Specifically, we analyze the influence of three 7 potentially important factors on the shape of dispersal kernels: distance-dependent competition, distance-8 dependent dispersal costs, and maternal investment reducing an offspring's dispersal costs through a 9 trade-off with maternal fecundity. We find that without maternal investment, competition and dispersal 10 costs lead to unimodal kernels, with increasing dispersal costs reducing the kernel's width and tail weight. 11Unexpectedly, maternal investment inverts this effect: kernels become bimodal at high dispersal costs. 12This increases a kernel's width and tail weight, and thus the fraction of long-distance dispersers, at the 13 expense of simultaneously increasing the fraction of non-dispersers. We finally demonstrate the qualitative 14 robustness of our results against variations in a majority of tested parameter combinations.

“…Mites hold great promise for such studies and have been used in multi-patch studies for some time (for example, Huffacker, 1958). The two-spotted spider mite (Tetranychus urticae) has been used in experimental manipulation (for example, Bitume et al, 2013) and selection studies (for example, Franhofer et al, 2014) on dispersal. Ariel dispersal behavior in this species is conditional on food level.…”

Effects of dispersal plasticity on population divergence and speciation

Phenotypic plasticity is thought to have a role in driving population establishment, local adaptation and speciation. However, dispersal plasticity has been underappreciated in this literature. Plasticity in the decision to disperse is taxonomically widespread and I provide examples for insects, molluscs, polychaetes, vertebrates and flowering plants. Theoretical work is limited but indicates an interaction between dispersal distance and plasticity in the decision to disperse. When dispersal is confined to adjacent patches, dispersal plasticity may enhance local adaptation over unconditional (non-plastic) dispersal. However, when dispersal distances are greater, plasticity in dispersal decisions strongly reduces the potential for local adaptation and population divergence. Upon dispersal, settlement may be random, biased but genetically determined, or biased but plastically determined. Theory shows that biased settlement of either type increases population divergence over random settlement. One model suggests that plasticity further enhances chances of speciation. However, there are many strategies for deciding on where to settle such as a best-of-N strategy, sequential sampling with a threshold for acceptance or matching with natal habitat. To date, these strategies do not seem to have been compared within a single model. Although we are just beginning to explore evolutionary effects of dispersal plasticity, it clearly has the potential to enhance as well as inhibit population divergence. Additional work should pay particular attention to dispersal distance and the strategy used to decide on where to settle.
