Behavioral Flexibility and the Conservation Value of Howler Monkey Populations in Small Habitat Patches. [PDF]

open access: yesAm J Primatol
Standardized effect sizes of the relationships between predictor and response variables. Natural logarithms are denoted as “ln.” Open circles (blue outline) indicate mostly positive effects; solid circles (red filled) indicate mostly negative effects. ABSTRACT Species occupying small habitat patches and exhibiting behavioral and ecological flexibility ...

Genetic Diversity Impacts Climate-Induced Species Range Shifts. [PDF]

open access: yesEcol Lett
Genetic diversity may buffer species against climate‐driven range contractions and facilitate expansions, but its role at a global scale remains unclear. Using 4673 range shift estimates for 1888 species, we show that higher genetic diversity reduces trailing edge contractions under rapid warming and accelerates leading edge expansions under moderate ...
