BIOSYS-1: a FORTRAN program for the comprehensive analysis of electrophoretic data in population genetics and systematics

TL;DR: First principal component values and the higher allele variability found in southern populations seem to concord with the palynological evidence for a southern origin of beech in the peninsular part of Italy.

American Journal of Botany

TL;DR: In this article, the authors investigated the genetic variation among 12 populations of the American chestnut (Castanea dentata) and found that approximately 10% of the allozyme diversity resided among populations.

An empirical test of predictions of two competing models for the maintenance and fate of hybrid zones: both models are supported in a hard-clam hybrid zone.

Evolution

TL;DR: The structure and genetic architecture of this hybrid zone appear to be products of a complicated interaction between both types of selective forces cited in the two competing models, demonstrating that selection in the zone is complex, and that characteristics of both the tension‐zone and ecotone models are present.

The effect of serpentine on the population structure of silene dioica (caryophyllaceae).

Anna Westerbergh, +1 more

Evolution

TL;DR: The results suggest that S. dioica has colonized serpentine repeatedly and that the tolerant populations have a multiple origin.

TL;DR: The populations examined appear to be part of the same gene pool, indicating that gene flow via dispersal through the sea occurs today, and it is unlikely that South American and Australasian populations would be conspecific if they have exchanged no migrants since the break-up of Gondwana at the end of the Mesozoic.
