Emigration propensity and flight performance are decoupled in a butterfly

Abstract: Dispersal, defined as any movements potentially leading to gene flow, is a major process driving a species’ capacity to cope with human‐induced environmental modifications. However, the dispersal process is multi‐causal, which currently hinders predictions regarding a species’ resilience to global change. We used a multifaceted approach to disentangle the relative importance of a suite of dispersal‐related factors in the butterfly Lycaena tityrus, including condition‐ (morphology and behavior) and context‐ (en… Show more

“…This could indicate that flight performance, on the one hand, and movement and exploration on the other are not intimately associated in B. anynana, which has been suggested before . Interestingly, this is also in line with experiments under semi-natural conditions in the butterfly Lycaena tityrus, where emigration propensity was not linked to individual condition and flight ability (Reim et al, 2018). However, our laboratory tests were not designed to test for dispersal, so any conclusions with regard to dispersal in real landscapes should be drawn carefully.…”

“…This suggests that at least some individuals are highly mobile and have the potential to disperse over long distances, although Lycaena species are among the least mobile butterfly species (Ricketts, 2001). Note that we exclusively sampled males, while females are often the more dispersive sex in butterflies (Fischer et al., 1999; Hanski et al., 2004; Reim et al., 2018). This, however, should not affect results based on genetic relatedness in a sexually reproducing organism.…”

“…In addition, similar experimental approach, i.e. creation of habitat variability in small-sized outdoor mesocosms, has proven powerful to study the local determinants of emigration decisions in other small animals (Trochet et al 2013;Legrand et al 2015;Reim et al 2018). In this study, at first glance, the matrix type had no effect on toad's willingness to move.…”
