“…The effect of maternal food limitation on juvenile dispersal appears to be mediated in part by the vertebrate stress hormone corticosterone; ex perimental application of corticosterone to gravid female common lizards caused their offspring to be more likely to disperse (de Fraipont et al 2000;Vercken et al 2007). Further, the effects of corticosterone on offspring dispersal can be modified by maternal condition; corticosterone ad dition decreased dispersal rates in offspring of larger fe males (Meylan et al 2002. These results suggest that multiple maternal signals of stressful or poor con ditions may increase offspring dispersal propensity.…”

Ecological and evolutionary processes are affected by forces acting at both local and regional scales, yet our understanding of how these scales interact has remained limited. These processes are fundamentally linked through individuals that develop as juve niles in one environment and then either remain in the natal habitat or disperse to new environments. Empirical studies in a diverse range of organisms have demonstrated that the conditions experienced in the natal habitat can have profound effects on the adult phenotype. This environmentally induced phenotypic variation can in turn affect the probability that an individual will disperse to a new environment and the ecological and evolutionary impact of that individual in the new environment. We synthesize the literature on this process and propose a framework for exploring the linkage between local devel opmental environment and dispersal. We then discuss the ecological and evolutionary implications of dispersal asymmetries generated by the effects of natal habitat conditions on individual phenotypes. Our review indicates that the influence of natal habitat conditions on adult phenotypes may be a highly general mechanism affecting the flow of individuals between populations. The wealth of information already gathered on how local conditions affect adult phenotype can and should be integrated into the study of dispersal as a critical force in ecology and evolution.

“…These two results suggest that the deposition of low concentrations of yolk androgens into the eggs of nests with parasites might thus be a female strategy to promote philopatry of parasitized offspring and thus to increase her offspring's and thereby her own fitness. Similarly, exposure to prenatal corticosterone decreases juvenile dispersal in the common lizard, but this result depended on interactions with maternal-age or physical condition [141,185]. Juveniles from older females treated with corticosterone showed a lower propensity for dispersal; in contrast young females treated with corticosterone produced offspring with higher dispersal behaviours [141].…”

“…In reptiles, the effects of prenatal exposure to corticosterone may affect size, body condition, growth and sex determination [150,[184][185][186]. In most cases, these corticosterone-mediated morphological changes seem deleterious; the decrease of body condition observed can be caused by impairing immune system function and mobilization of energy stores [187].…”

A challenge to ecologists and evolutionary biologists is predicting organismal responses to the anticipated changes to global ecosystems through climate change. Most evidence suggests that short-term global change may involve increasing occurrences of extreme events, therefore the immediate response of individuals will be determined by physiological capacities and life-history adaptations to cope with extreme environmental conditions. Here, we consider the role of hormones and maternal effects in determining the persistence of species in altered environments. Hormones, specifically steroids, are critical for patterning the behaviour and morphology of parents and their offspring. Hence, steroids have a pervasive influence on multiple aspects of the offspring phenotype over its lifespan. Stress hormones, e.g. glucocorticoids, modulate and perturb phenotypes both early in development and later into adulthood. Females exposed to abiotic stressors during reproduction may alter the phenotypes by manipulation of hormones to the embryos. Thus, hormone-mediated maternal effects, which generate phenotypic plasticity, may be one avenue for coping with global change. Variation in exposure to hormones during development influences both the propensity to disperse, which alters metapopulation dynamics, and population dynamics, by affecting either recruitment to the population or subsequent life-history characteristics of the offspring. We suggest that hormones may be an informative index to the potential for populations to adapt to changing environments.

“…There are many ways of calculating these parameters; most of them include calculating the body mass and proportions between the animal's body parts. An example of a condition index measure would be snout-vent length (SVL) measurement divided by body mass (Bradshaw and De'ath, 1991;Olsson and Shine, 1997;Oppliger and Clobert, 1997;De Fraipont et al, 2000;Pearson, 2000;Meylan et al, 2002). The results of this measurement are sometimes additionally log-transformed to allow further analysis.…”
