1 mar 2022 · In combining aspects of genetic networks and landscape graphs, researchers can use resistance surfaces and spatial distance between nodes to determine the probability of dispersal between genetic nodes (Draheim et al., 2016) which has considerable value to analyses focussed on dispersal or understanding meta-population source-sink dynamics.
10 lut 2020 · The geographical factors included regions, bathymetry and distance to shore that increases with ocean depth for marine species only, and elevation, basin area, slopes (average and range) and...
24 maj 2017 · In this simulation study, we analyze the behavior of different genetic distances in Island (null hypothesis) and stepping stone models displaying varying neighborhood sizes.
This section focuses first on how we estimate distances, depending upon the level of interest, and then highlights some approaches for visualizing and gaining inferences from the distance matrix itself.
Genetic distance is a measure of the genetic divergence between species or between populations within a species, whether the distance measures time from common ancestor or degree of differentiation. Populations with many similar alleles have small genetic distances.
13 paź 2016 · Isolation by distance (IBD) and the existence of effective barriers to gene flow, the Atlantic Ocean and Pico Mountain, were found to be related with genetic distance.
2 sie 2018 · Overall, we calculate and compare measures of resistance distances based on idealized, historical, and contemporary forest composition to provide a more rigorous assessment of the effects of landscape structure on genetic differentiation patterns in Northern Spotted Owls.
