Alpine ecosystems are particularly vulnerable to climate change. For widely distributed
alpine specialists, rear‐edge populations are disproportionately important; it is expected that …

Aim High‐elevation specialist species are threatened by climate change and habitat loss,
and their distributions are becoming increasingly reduced and fragmented. In such a …

Mountains naturally offer variable habitat conditions, but their biodiversity is currently facing
the extra challenge of adapting to rapid environmental shifts that are much more …

In migratory birds, among‐and within‐species heterogeneity in response to climate change
may be attributed to differences in migration distance and environmental cues that affect …

Management boundaries are often delimited by political and social factors, whereas animal
movements are affected by ecological and geophysical constraints. Thus, understanding …

Migration is used by many species as a strategy to deal with a seasonally changing
environment. For some species, migration patterns can vary across different or even within …

Aim Climate warming is shifting the bioclimatic optima of species towards mountaintops, but
the ability of organisms to track these changes also depends on their dispersal skills. Here …

Intraspecific morphological variation of organisms is known to be influenced by several
factors, but the role of habitat availability has been scarcely investigated. Studying bird wing …

Background Small songbirds respond and adapt to various geographical barriers during
their annual migration. Global flyways reveal the diverse migration strategies in response to …

Background Understanding which intrinsic and extrinsic factors dictate decision-making
processes such as leaving the natal area or not (migratory vs resident strategy), departure …
