TL;DR: It is suggested that populations will vary in response to climate change depending on how climate affects the demographic parameters that contribute most to population growth.

TL;DR: The results suggest that, up to the 1950s, murrelet populations in the Georgia Basin were capable of growing and were probably limited by factors other than diet quality, and imply that murrelets were often, but not solely, limited by diet quality.

TL;DR: Song sparrows inhabiting Mandarte Island, British Columbia, Canada, used 20 years of data to test whether a male’s song repertoire size, a secondary sexual trait, predicted overall measures of male or offspring fitness, and suggest that female song sp Sparrows would gain immediate and intergenerational fitness benefits by pairing with males with large song repertoires.

TL;DR: Data indicate substantial and apparently sex-specific inbreeding effects on immune response, implying that inbred hosts may be relatively susceptible to parasitic infection to differing degrees in males and females.

TL;DR: This study examined whether limits on the volume of faeces produced by oribi Ourebia ourebi, in Serengeti National Park, Tanzania, caused territorial males to regulate their output and prioritize the placement ofFaecal marks.
