“…Tracking of the performance of birds born in these areas that survived to breeding age, in relation to whether they recruited to the poor or good areas, gives a result that is more in line with the silver spoon model than the environmental matching model ( figure 4, compared with figure 2a,b). However being a field study, many aspects of settlement are not controlled; it is possible, for example, that genetic effects are also involved here, though this seems to be unlikely since the population is small, and birds do move around the island making it unlikely that specific lineages have developed in the two areas (Reid et al 2003(Reid et al , 2006.…”

Phenotypic development is the result of a complex interplay involving the organism's own genetic make-up and the environment it experiences during development. The latter encompasses not just the current environment, but also indirect, and sometimes lagged, components that result from environmental effects on its parents that are transmitted to their developing offspring in various ways and at various stages. These environmental effects can simply constrain development, for example, where poor maternal condition gives rise to poorly provisioned, low-quality offspring. However, it is also possible that environmental circumstances during development shape the offspring phenotype in such a way as to better prepare it for the environmental conditions it is most likely to encounter during its life. Studying the extent to which direct and indirect developmental responses to environmental effects are adaptive requires clear elucidation of hypotheses and careful experimental manipulations. In this paper, I outline how the different paradigms applied in this field relate to each other, the main predictions that they produce and the kinds of experimental data needed to distinguish among competing hypotheses. I focus on birds in particular, but the theories discussed are not taxon specific. Environmental influences on phenotypic development are likely to be mediated, in part at least, by endocrine systems. I examine evidence from mechanistic and functional avian studies and highlight the general areas where we lack key information.

“…In treatments that prevented natal habitat effects, individuals moving from high-to low-quality habitat patches immediately assume the phenotype of individuals born in low-quality habitat, which prevents the beneficial silver spoon effect. In many systems, development in high-quality habitat increases fecundity, indicating that silver spoon effects are common in nature (18,34,37,48). Thus, our results Table 1.…”

“…Studies in more natural field settings indicate that natal experience can significantly affect individual traits and population dynamics in a variety of taxa [roe deer (50), choughs (48), bryozoans (27), parrots (51), bluebirds (15)], suggesting that patterns similar to our laboratory system are likely across the landscape in natural systems. Ecologists, conservationists, and wildlife managers alike should be aware of the quality/type of habitat that individuals come from and the possibility of unexpected dynamics in focus areas caused by carryover effects of natal habitats on immigrating individuals.…”

“…Ecologists, conservationists, and wildlife managers alike should be aware of the quality/type of habitat that individuals come from and the possibility of unexpected dynamics in focus areas caused by carryover effects of natal habitats on immigrating individuals. This aspect highlights a possible difficulty in identifying carryover effects in nature, given that it could be critical to know where dispersing individuals come from and what conditions they experienced to identify potential carryover effects when natal and new habitats differ (16,30,48,52,53). Furthermore, carryover effects can alter dispersal decisions and capabilities (16,44).…”

Understanding how changes to the quality of habitat patches affect the distribution of species across the whole landscape is critical in our human-dominated world and changing climate. Although patterns of species' abundances across a landscape are clearly influenced by dispersal among habitats and local species interactions, little is known about how the identity and origin of dispersers affect these patterns. Because traits of individuals are altered by experiences in their natal habitat, differences in the natal habitat of dispersers can carry over when individuals disperse to new habitats and alter their fitness and interactions with other species. We manipulated the presence or absence of such carried-over natal habitat effects for up to eight generations to examine their influence on two interacting species across multiple dispersal rates and different habitat compositions. We found that experimentally accounting for the natal habitat of dispersers significantly influenced competitive outcomes at all spatial scales and increased total community biomass within a landscape. However, the direction and magnitude of the impact of natal habitat effects was dependent upon landscape type and dispersal rate. Interestingly, effects of natal habitats increased the difference between species performance across the landscape, suggesting that natal habitat effects could alter competitive interactions to promote spatial coexistence. Given that heterogeneity in habitat quality is ubiquitous in nature, natal habitat effects are likely important drivers of spatial community structure and could promote variation in species performance, which may help facilitate spatial coexistence. The results have important implications for conservation and invasive species management.carryover effects | natal habitat effect | competition | metacommunity | dispersal C ommunities do not exist in a vacuum; instead, they are connected to each other through dispersal of interacting species. Consequently, dispersal among different kinds of habitat patches is increasingly recognized as a key factor driving the dynamics and structure of communities from local to regional spatial scales (1-5). In classic models, the persistence and dynamics of populations within a patch are determined by two factors: the rate of dispersal between patches of habitat and the species fitness within each local patch (6-8). This view has persisted into metacommunity theory (multiple communities connected by dispersal of individuals between the patches of habitat they occur in) as well, where the influence of dispersers on community dynamics is generally considered only in terms of their numbers (i.e., dispersal rate) and habitat-specific performance (1, 9-11). Implicit in this case, and for most of spatial ecology, is that the interactions and population dynamics within a habitat are solely determined by the quality of that habitat. However, this approach ignores the often substantial variation in individual traits and fitness within and across habitats in a natural sys...

“…Redbilled Choughs (Pyrrhocorax pyrrhocorax) born after a period of unfavorable weather had reduced lifespans and produced fewer fledglings over the lifetime and, in the case of males, reduced reproductive success at age 3 years (Reid et al 2003). Similarly, choughs that fledged in an unfavorable region showed poor adult survival, irrespective of the region they bred in (Reid et al 2006). Oystercatchers (Haematopus ostralegus) that fledged in poor quality natal territories bred in poor quality territories (generally distinct from their natal ones) and showed diminished lifetime reproductive success (van de Pol et al 2006).…”
