Background Theory predicts that lower dispersal, and associated gene flow, leads to
decreased genetic diversity in small isolated populations, which generates adverse …

Little is known about the connection between demography and dispersal in
metapopulations. The meta‐analysis of the population time series of five butterfly species …

Demographic bottlenecks that occur when populations fluctuate in size erode genetic
diversity, but that diversity can be recovered through immigration. Connectivity among …

Dispersal is a key ecological process linking metapopulation dynamics in the landscape to
distribution patterns at larger spatial scales. In this study, we investigated the landscape …

Habitat fragmentation is a ubiquitous by-product of human activities that can alter the genetic
structure of natural populations, with potentially deleterious effects on population …

Abstract The Glanville fritillary butterfly (Melitaea cinxia) has been studied in the Åland
Islands in Finland since 1991, where it occurs as a classic metapopulation in a large …

Metapopulation dynamics lead to predictable patterns of habitat occupancy, population
density and trophic structure in relation to landscape features such as habitat patch size and …

Dispersal evolution impacts the fluxes of individuals and hence, connectivity in
metapopulations. Connectivity is therefore decoupled from the structural connectedness of …

Habitat fragmentation may interrupt trophic interactions if herbivores and their specific
parasitoids respond differently to decreasing connectivity of populations. Theoretical models …

Understanding connectivity among populations in fragmented landscapes is of paramount
importance in species conservation because it determines their long-term viability and helps …
