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