It is appropriate to reflect on the contribution of this powerful method of gene dispersal.
The population genetics theory offers a powerful framework for estimating dispersal distances and migration rates from molecular data.
OOF: New research reveals the Food and Drug Administration, doctors and drugmakers mishandled the dispersal of the powerful opioid fentanyl, which led to thousands of ineligible patients gaining access to the painkiller.
"I think we have proved that there is no need to claim human transportation of the sweet potato across the Pacific – there is much more powerful evidence for naturally driven dispersal," said Pablo Muñoz-Rodríguez, a PhD student and first author of the research from the University of Oxford.
Thus, environmental variability combined with constraints on dispersal could be a powerful selective force for an enlarged brain in island bird species.
The detected high diversity of fungi associated with Collembola suggests that dispersal by arthropod vectors may represent a powerful alternative to aerial dispersal of fungal propagules.
Both positive and negative factors can have powerful selective effects on human behaviour and patterns of settlement and dispersal.
Combining habitat models with individual-based models is a powerful and robust approach that could be widely applied to delineate dispersal corridors of large carnivores and quantify patch connectivity even if data are scarce.
An analogous pattern has been described for riverine cichlid fish from the lower Congo basin, where powerful rapids in the main river form a strong barrier to dispersal between shallow-water cichlids species, effectively isolating populations on opposite banks of the river [ 60].
By generating individual-specific genotypes, non-invasive genetic studies have evaluated the effective population size of species, inferred their dispersal patterns and assessed their genetic diversity and thus provide a powerful biomonitoring tool for populations with minimal perturbation to the species under study [19]-[21] [19]-[21]
