Climate change affects timing of reproduction in many bird species, but few studies have
investigated its influence on annual reproductive output. Here, we assess changes in the …

Climate warming is increasingly exposing wildlife to sublethal high temperatures, which may
lead to chronic impacts and reduced fitness. Telomere length (TL) may link heat exposure to …

Many wild populations are experiencing temporal changes in life-history and other
phenotypic traits, and these changes are frequently assumed to be driven by climate change …

Aim A decline in body size has been proposed as a universal response to global warming,
but this is often questioned. We describe and characterize recent morphological changes in …

Rapid anthropogenic climate change potentially severely reduces avian breeding success.
While the consequences of high temperatures and drought are reasonably well-studied …

Predation is a biological interaction that influences demographic patterns by modifying
community structure. In the current ecological crisis, there is a need to better understand the …

Understanding how populations respond to climate is fundamentally important to many
questions in ecology, evolution, and conservation biology. Climate is complex and …

Despite a large body of literature investigating the effects of long-term climate trends on
birds, the effects of short-term weather on individual body condition are less established …

Declines in body size can be an advantageous physiological response to warming
temperatures, or a result of physiological and nutritional stress. Either way, studies often …

Populations of many common bird species are declining in Europe and effective
conservation measures require an understanding of both the environmental and …
