TL;DR: It is suggested that walking humans can disperse seeds to very long distances, up to at least 10 km, and some of the first quantified dispersal kernels for HMD are provided.

TL;DR: Paternity analysis of seedlings as well as juveniles from a restricted area of natural regeneration was used to quantify pollen- and seed-mediated gene flow, respectively and suggests small-scale isolation by distance due to short-distance gene flow helps to explain the reduced diversity in the juveniles.

TL;DR: The results indicate that both habitat degradation and fragmentation have negative effects on populations of T. montanum, but affect different phases of the life cycle, and in the short term, the effects of habitat degradation are more important than those of fragmentation.

TL;DR: In this article, a simulation model for the spread of plant species between human settlements was developed on the basis of extensive sociological and ecological data on a regional scale with regard to the sociological data, human movement behaviour defined the amount of exchange between the settlements.

TL;DR: A powerful system of nuclear microsatellite DNA (nSSR) fingerprints, standardized by allelic ladders and reference genotypes, is presented, confirming the demand for rigorous standards in poplar breeding programs and studies in introgressive gene flow.
