28 lis 2019 · For PCA, the components and their loadings provide an approximation to the genetic distance matrix between individuals. We use the median PCA values of individuals across two, ten, or 100 PC components to produce an expected genetic distance matrix between populations.
view the program consists in extracting from the genetic/lexical distances a set of reconstructed geographical positions to be compared with the real ones. We show that geographical recovering is successful when the genetic/lexical distances are not a simple consequence of phylogenesis but
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.
1 mar 2002 · When populations can be defined a priori, one option is to analyze genetic “isolation by distance” (sensu Wright 1943) by plotting the genetic similarity (or distance) among population pairs as a function of the geographic distance between those pairs.
Studying isolation by distance can provide useful demographic information. To analyze isolation by distance from molecular data, one can use some kind of genetic distance or coalescent...
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.
We show that geographical recovering is successful when the genetic/lexical distances are not a simple consequence of phylogenesis but also of horizontal transfers as, for example, vocabulary borrowings between different languages.
