A multi-locus phylogeny of Nectogalini shrews and influences of the paleoclimate on speciation and evolution.

A climate for speciation: rapid spatial diversification within the Sorex cinereus complex of shrews.

The cyclic climate regime of the late Quaternary caused dramatic environmental change at high latitudes. Although these events may have been brief in periodicity from an evolutionary standpoint, multiple episodes of allopatry and divergence have been implicated in rapid radiations of a number of organisms. Shrews of the Sorex cinereus complex have long challenged taxonomists due to similar morp...

Phylogeny and morphological traits evolution of Astragalus sects. Acanthophace and Aegacantha in Iran on the basis of nrDNA ITS and rpl32-trnLUAG sequences

In this study, phylogenetic relationships and evolutionary trends of morphological characters of Astragalus sects. Acanthophace and Aegacantha were studied using nrDNA ITS and rpl32-trnLUAG datasets while Astragalus stocksii was selected as the outgroup. The phylogenetic results indicated the non-monophyly of A. sect. Acanthophace in its current circumscription due to the distant exclusion of A...

Perspectives in taxonomy and phylogeny of the genus Astragalus (Fabaceae): a review

The genus Astragalus L. (Fabaceae) is reviewed from both phyloenetic and taxonomic points of view. As the largest genus of flowering plants it has attracted many researchers, but much work remains to be done. A short taxonomic history with special focus on infrageneric classification of the genus, a list of phylogenetic studies including the applied markers and sampling strategies as well a...

Editorial: Could Speciation Across Evolution be Governed by Genetic Switch Codes at Short Tandem Repeats?

Do geological or climatic processes drive speciation in dynamic archipelagos? The tempo and mode of diversification in Southeast Asian shrews.

Geological and climatic processes potentially alter speciation rates by generating and modifying barriers to dispersal. In Southeast Asia, two processes have substantially altered the distribution of land. Volcanic uplift produced many new islands during the Miocene-Pliocene and repeated sea level fluctuations during the Pleistocene resulted in intermittent land connections among islands. Each ...
