Significant advances have been made in species delimitation and numerous methods can
test precisely defined models of speciation, though the synthesis of phylogeography and …

With limited sampling, geographic variation within a single species can be difficult to
distinguish from interspecific variation, confounding our ability to draw accurate species …

The biota of Sulawesi is noted for its high degree of endemism and for its substantial levels
of in situ biological diversification. While the island's long period of isolation and dynamic …

Over the past decade, museum genomics studies have focused on obtaining DNA of
sufficient quality and quantity for sequencing from fluid-preserved natural history specimens …

A growing number of publications presenting results from sequencing natural history
collection specimens reflect the importance of DNA sequence information from such …

Aim Current distributions of widespread North American (NA) species have been shaped by
Pleistocene glacial cycles, latitudinal temperature gradients, sharp longitudinal habitat …

Numerous mechanisms can drive speciation, including isolation by adaptation, distance,
and environment. These forces can promote genetic and phenotypic differentiation of local …

Evolutionary processes behind lineage divergence often involve multidimensional
differentiation. However, in the context of recent divergences, the signals exhibited by each …

A fundamental objective of evolutionary biology is to understand the origin of independently
evolving species. Phylogenetic studies of species radiations rarely are able to document …

Divergence dating analyses in systematics provide a framework to develop and test
biogeographic hypotheses regarding speciation. However, as molecular datasets grow from …
