摘要: AbstractEcological invasions are a major worldwide problem exacting tremendous economic and ecological costs. Efforts to explain variability in invasion speed impact by searching for combinations of conditions species traits associated with have met mixed success. We use simulation model that integrates insights from life-history theory, animal personalities, network spatial ecology derive new mechanism explaining variation show spread occurs most rapidly when (1) includes mix or personality types differ density-dependent performance dispersal tendencies, (2) the differences between intermediate magnitude, (3) patch connections number widely spread. Within-species polymorphism phenotype (e.g., strategies personality), feature not included previous models, is important overcoming fact different trai...
