“…The effects of environment on dispersal phenotypes can carryover across discrete life history stages (Arambourou et al 2017) and generations (Krug 2009;Crean & Marshall 2009;Meylan et al 2012;Bitume et al 2014;Van Allen & Bhavsar 2014;Van Allen and Rudolph 2016). Studies investigating how condition and phenotype dependence interact to influence dispersal are notable, yet relatively rare (Hansson et al 2003;Chaput-Bardy et al 2010;Selonen & Hanski 2010). The influence of juvenile environment on how far an individual disperses later in life remains even less well understood (Clobert et al 2009;Wey et al 2015).…”

The importance of growing up: juvenile environment influences dispersal of individuals and their neighbours

Dispersal is a key ecological process that is strongly influenced by both phenotype and environment. Here, we show that juvenile environment influences dispersal not only by shaping individual phenotypes, but also by changing the phenotypes of neighbouring conspecifics, which influence how individuals disperse. We used a model system (Tribolium castaneum, red flour beetles) to test how the past environment of dispersing individuals and their neighbours influences how they disperse in their current environment. We found that individuals dispersed especially far when exposed to a poor environment as adults if their phenotype, or even one‐third of their neighbours’ phenotypes, were shaped by a poor environment as juveniles. Juvenile environment therefore shapes dispersal both directly, by influencing phenotype, as well as indirectly, by influencing the external social environment. Thus, the juvenile environment of even a minority of individuals in a group can influence the dispersal of the entire group.

“…Morphology has been shown to be a highly variable trait in damselflies, and shifts in morphology may represent either an evolutionary or plastic response to abiotic conditions or altered competitive regimes (Chaput‐Bardy et al . ; Hassall ). Thus, we investigated effects of climate and altered competitive regimes on body size.…”

“…In our study population, dispersal behaviour is correlated with wing length, with individuals that disperse to another river having on average longer wings (+0.33 ± 0.12 mm, t = 2.62, P = 0.009, unpublished data) than individuals that stay in their natal river (philopatric individuals). Similar size‐dependent dispersal behaviour has been shown in a range of other species (Paradis et al ., ; Skjelseth et al ., ; Dawideit et al ., ) (but see Chaput‐Bardy et al ., ). This, combined with typically higher probabilities of inbreeding in philopatric individuals (Szulkin & Sheldon, ), has the potential to generate a negative association between wing length and the probability of inbreeding.…”

“…Szulkin & Sheldon, ) and differ phenotypically from the latter. For example, in birds and many insects, dispersal behaviour is a function of body size, especially wing length, with bigger‐ or longer‐winged individuals dispersing further (Paradis et al ., ; Skjelseth et al ., ; Dawideit et al ., ) (but see Chaput‐Bardy et al ., ). In line with this, differences between philopatric individuals and dispersers have been detected in a range of morphological, behavioural and life‐history traits, and in taxa ranging from single‐cell species to primates (reviewed in Ronce & Clobert, ).…”

Phenotype‐associated inbreeding biases estimates of inbreeding depression in a wild bird population

Inbreeding depression is usually quantified by regressing individual phenotypic values on inbreeding coefficients, implicitly assuming there is no correlation between an individual's phenotype and the kinship coefficient to its mate. If such an association between parental phenotype and parental kinship exists, and if the trait of interest is heritable, estimates of inbreeding depression can be biased. Here we first derive the expected bias as a function of the covariance between mean parental breeding value and parental kinship. Subsequently, we use simulated data to confirm the existence of this bias, and show that it can be accounted for in a quantitative genetic animal model. Finally, we use long-term individual-based data for white-throated dippers (Cinclus cinclus), a bird species in which inbreeding is relatively common, to obtain an empirical estimate of this bias. We show that during part of the study period, parents of inbred birds had shorter wings than those of outbred birds, and as wing length is heritable, inbred individuals were smaller, independent of any inbreeding effects. This resulted in the overestimation of inbreeding effects. Similarly, during a period when parents of inbred birds had longer wings, we found that inbreeding effects were underestimated. We discuss how such associations may have arisen in this system, and why they are likely to occur in others, too. Overall, we demonstrate how less biased estimates of inbreeding depression can be obtained within a quantitative genetic framework, and suggest that inbreeding and additive genetic effects should be accounted for simultaneously whenever possible.
