Body size divergence promotes post-zygotic reproductive isolation in centrarchids
Question: Does morphological divergence accelerate the evolution of post-zygotic reproductive isolation? Data incorporated: Estimates of divergence time between species, body size divergence, and hybrid embryo viability in the freshwater fish family Centrarchidae. Method of analysis: We estimated the age of each node in the phylogeny using penalized likelihood, calibrated with multiple fossil d...
متن کاملPost-zygotic reproductive isolation between sympatric taxa in the Chamaecrista desvauxii complex (Leguminosae-Caesalpinioideae).
BACKGROUND AND AIMS Differences in the mating systems and the mechanisms of reproductive isolation between Chamaecrista desvauxii var. graminea and C. desvauxii var. latistipula were examined in the Chapada Diamantina, Brazil. These taxa occur sympatrically, and their populations demonstrate marked morphological differences. The objective of the present work was to determine if reproductive iso...

15 صفحه اولPost-zygotic reproductive isolation among populations of Iris atropurpurea: the effect of spatial distance among crosses and the role of inbreeding and outbreeding depression in determining niche width
Question: What is the role of inbreeding and outbreeding depression in creating spatial patterns of reproductive isolation among populations within a species? Hypothesis: A combination of inbreeding and outbreeding effects create an optimal crossing distance at which reproductive isolation is minimal. Organism: Iris atropurpurea Dinsm., an endangered and endemic Israeli plant, with a fragmented...
