Summary As ectothermic organisms, butterflies have widely been used as models to explore the predicted impacts of climate change. However, most studies only one life stage; our best knowledge, none integrated impact temperature on vital rates all stages for a species conservation concern. Besides, population viability analysis are based yearly growth rate, precluding implementation and assessment important change scenarios, where occurs mainly, or differently, during some seasons. Here, we...
Abstract Population viability analyses (PVAs) contribute to conservation theory, policy, and management. Most PVAs focus on single species within a given landscape address specific problem. This specificity often is reflected in the organization of published PVA descriptions. Many lack structure, making them difficult understand, assess, repeat, or use for drawing generalizations across studies. In an assessment comparing existing guidelines, we found that model selection was rarely...
Abstract In contrast to several organisms that have already shown range shifts the north as a response climate change, southern populations of relict species are trapped in isolated altitudinal habitats. Therefore, there is growing interest better understand their habitat use, with particular attention thermal aspects and associated significance for management. We address this issue by study larval use relative vegetation structure microclimate glacial butterfly peat bog ecosystems, using...
The precise knowledge of ecological resources and conditions required by species threatened rapidly changing environmental is prime importance for conservation biology. Transferability this between with similar requirements often assumed, but rarely tested. This especially the case glacial relict populations confined to climate‐habitat traps from where they cannot move rejoin areas suitable conditions. Using two butterflies as model organisms, we first quantitatively define larval adult...
Understanding dispersal is of prime importance in conservation and population biology. Individual traits related to motion navigation during may differ: (1) among species differing habitat distribution, which turn, lead interspecific differences the potential for costs dispersal, (2) populations a that experiences different levels fragmentation; (3) individuals their strategy (4) between sexes due sexual behaviour tendencies. In butterflies, visual system plays central role but exactly how...
Abstract Aims Multiple environmental changes simultaneously altering the biotic and abiotic context of species are threatening communities ecosystems worldwide. Exploration mitigation eco‐evolutionary impacts global change threats correspondingly major components conservation research, yet joint remain poorly studied. Moreover, in rarely considered when assessing change‐induced range shifts. We aim to unravel contributions habitat fragmentation, climate warming, genetic variation...
Landscapes are often considered as islands of suitable habitat patches located in a hostile and homogeneous matrix. Variation matrix quality, however, can be differently perceived by individuals, generating variation movements related to external conditions (i.e., contrasted boundaries, corridors, or barriers) and/or individual phenotypes sex age). Accordingly, may differ both among species conspecific individuals various age sex. Here, we quantified sex-dependent condition-dependent...
Community assembly is a combination of ecological, evolutionary, and stochastic processes. Separating out the abiotic biotic processes (such as limiting similarity or environmental filtering) from central to developing cogent approach for understanding patterns in ecological community structure organization. Using butterfly communities fragmented landscape, we tested hypothesis that local filtering drives character convergences traits species belonging different clades. We found that, while...
The butterfly Boloria aquilonaris is a specialist of oligotrophic ecosystems. Population viability analysis predicted the species to be stable in Belgium and collapse Netherlands with reduced host plant quality expected drive decline latter. We tested this hypothesis by rearing B. caterpillars from Belgian Dutch sites on plants (the cranberry, Vaccinium oxycoccos). was lower than one conferring caterpillar growth rate survival. Reintroduction and/or supplementation may necessary ensure...
A functional definition of the habitat-concept based on ecological resources incorporates three interconnected parameters: composition, configuration and availability resources. The intersection those parameters represents habitat a given population or species. Resource composition refers to co-occurrence required by each individual complete its life cycle. both way are spatially distributed within all organized in space. accessibility procureability Variation these variables is predicted...
Addressing genetic issues in the management of fragmented wild populations threatened species is one most important challenges conservation biology. Nowadays, a diverse array molecular methods exists to assess diversity and differentiation such as allozymes, dominant markers co-dominant markers. However it remains worthwhile i) compare estimates obtained using those several order ii) test their relative utility, reliability relevance iii) impact these results for design species-specific...
1. Insects locate mobile resources like prey items or mates using either sit-and-wait ('perching') active ('patrolling') searching strategies. The strategy can be accompanied by defending and monopolising a site through territorial behaviour. 2. present study focuses on the perching behaviour in males of speckled wood butterfly (Pararge aegeria L.). Recent studies suggested that selection territories (i.e. sunlit patches forest floor) is driven structural characteristics affect male visual...
Abstract Obtaining an accurate quantification of population size is often prime importance in ecology and conservation biology (e.g. viability analysis, a basic step for assessing species status given area guiding effective conservation). When obtaining reliable absolute (vs. relative) required, Mark–Release–Recapture ( MRR ) method choice many organisms. This highly but costly procedure terms time potential impact on sites. Consequently, less alternatives are desirable ecologists. We...
