Contrasting Patterns Of Divergence In Quantitative Traits And Neutral Dna Markers: Analysis Of Clinal Variation, Jay F. Storz
Contrasting Patterns Of Divergence In Quantitative Traits And Neutral Dna Markers: Analysis Of Clinal Variation, Jay F. Storz
Jay F. Storz Publications
Clinal variation in quantitative traits is often attributed to the effects of spatially varying selection. However, identical patterns can be produced by the interplay between purely stochastic processes (i.e. drift in combination with spatially restricted gene flow). One means of distinguishing between adaptive and nonadaptive causes of geographical variation is to compare relative levels of between population divergence in quantitative traits and neutral DNA markers. Such comparisons can be used to test whether levels of trait divergence attributable to additive genetic effects (as measured by QST) exceed null expectations based on the level of divergence at neutral marker …

Testing For Genetic Evidence Of Population Expansion And Contraction: An Empirical Analysis Of Microsatellite Dna Variation Using A Hierarchical Bayesian Model, Jay F. Storz, Mark Beaumont

The role of past climatic change in shaping the distributions of tropical rain forest vertebrates is central to long-standing hypotheses about the legacy of the Quaternary ice ages. One approach to testing such hypotheses is to use genetic data to infer the demographic history of codistributed species. Population genetic theory that relates the structure of allelic genealogies to historical changes in effective population size can be used to detect a past history of demographic expansion or contraction. The fruit bats Cynopterus sphinx and C. brachyotis (Chiroptera: Pteropodidae) exhibit markedly different distribution patterns across the Indomalayan region and therefore represent an …
