Habitat loss is leading to smaller fragmented populations, increasing their susceptibility to stochasticity. Quantifying the effects of demographic and environmental stochasticity on population dynamics and the contribution of selection versus drift to phenotypic change is essential to assess the potential consequences of environmental change. We examined how stochasticity influenced population growth and body mass changes ove...

Dispersal affects evolutionary processes by changing population size and genetic composition, influencing the viability and persistence of populations. Investigating which mechanisms underlie variation in dispersal phenotypes and whether populations harbour adaptive potential for dispersal is crucial to understanding the eco‐evolutionary dynamics of this important trait. Here, we investigate the genetic architecture of dispers...
