Invasion of pumpkinseed Lepomis gibbosus is facilitated by phenotypic plasticity across its invasion gradient
Tarkan, Ali Serhan; Karakuş, Uğur; Top Karakuş, Nildeniz; Keskin, Emre; Ünal, Esra Mine; Britton, John Robert (Springer, 2021)As a non-native species invades a new region, individuals at the range front are often characterised by differences in their traits and behaviours versus individuals in the established ‘core’ area. Here, differences in ... -
