Mountain regions are globally important areas for biodiversity but are subject to multiple
human‐induced threats, including climate change, which has been more severe at higher …

Long-term studies on the impacts of global change on reproduction are rare, even though
reproductive output can respond more quickly than species' abundances or distributions. We …

Mountain ecosystems naturally experience strong seasonal weather variations leading to a
brief peak in food availability that constrains bird reproduction. Climate change accentuates …

Demonstrated negative effects of increased temperatures on avian reproductive success
suggest a mechanism by which climate change may impact species persistence. High …

Mountains produce distinct environmental gradients that may constrain or facilitate both the
presence of avian species and/or specific combinations of functional traits. We addressed …

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 …

Across taxa, offspring size traits are linked to survival, and life-time fitness. Inclement
weather can be a major constraint on offspring growth and parental care. Despite the …

In seasonal environments, fluctuating early‐season weather conditions and short breeding
windows limit reproductive opportunities such that breeding earlier or later than the optimum …

Variation in offspring development is expected to be driven by constraints on resource
allocation between growth and maintenance (eg thermoregulation). Rapid post‐natal …

Mountains are excellent systems for studying biodiversity as they promote rapid species
turnover across relatively short elevational distances. Most research on biogeographic …
