Climate change is a major threat to species worldwide, yet it remains uncertain whether tropical or temperate species are more vulnerable to changing temperatures. To further our understanding of this, we used a standardised field protocol to (1) study the buffering ability (ability to regulate body temperature relative to surrounding air temperature) of neotropical (Panama) and temperate (the United Kingdom, Czech Republic an...

Gut microbial communities are complex and heterogeneous and play critical roles for animal hosts. Early‐life disruptions to microbiome establishment can negatively impact host fitness and development. However, the consequences of such early‐life disruptions remain unknown in wild birds. To help fill this gap, we investigated the effect of continuous early‐life gut microbiome disruptions on the establishment and development of...

Insect exposure to their predators can affect individuals and community processes, through direct consumption or nonlethal effects. However, the links between behavioral and physiological responses and stimuli needed for the development of predator avoidance are not clear. We subjected desert locusts ( Schistocerca gregaria ) to three nonlethal treatments, using great tits ( Parus major ) as a predator. The treatments included...
