Resumo
Climate change will likely be the most significant challenge faced by species in this century, and species’
ability to cope with climate change depends on their life history and ecological and evolutionary traits. Understanding
how these traits mediate species’ responses is beneficial for identifying more vulnerable species or prone to extinction
risk. Here, we carried out a literature review describing how four traits commonly used in vulnerability assessments
(i.e. clutch size, diet breadth, dispersal ability, and climatic tolerance) may determine species vulnerability. We also
portray the possible mechanisms that explain how these traits govern species responses to climate change. The
literature suggests different mechanisms operating for the evaluated traits. The mechanism of response to climate
change differs between species inhabiting tropical and temperate regions: while species from the temperate areas
may respond positively to temperature rise, tropical species may be severely affected. Since ectotherms depend on
environment temperature, they are more sensitive and present different response mechanisms from endotherms.
Keywords: Global warming; extinction risk; phenology; physiology; species traits.
