Post-zygotic isolation in cactophilic Drosophila: larval viability and adult life-history traits of D. mojavensis/D. arizonae hybrids.

Drosophila mojavensis and Drosophila arizonae are cactophilic flies that have been used extensively in speciation studies. Incomplete premating isolation, evidence of reinforcement, and a lack of recent introgression between these species point to a potentially important role for post-zygotic isolating barriers in this system. Other than hybrid male sterility, however, post-zygotic isolation be...

The effects of larval density on adult life-history traits in three species of Drosophila.

There is evidence that longevity and starvation resistance are determined by a common genetic mechanism. Starvation resistance in Drosophila strongly correlates with both fat content and longevity, and is affected by density during rearing. In this study, we examine how three species, Drosophila melanogaster, Drosophila ananassae and Drosophila willistoni, respond to three larval density treatm...

Timing of The First Zygotic Cleavage Affects Post-Vitrification Viability of Murine Embryos Produced In Vivo

Background Timing of the first zygotic cleavage is an accurate predictor of embryo quality. Embryos that cleaved early (EC) have been shown to exhibit higher developmental viability compared to those that cleaved at a later period (LC). However, the viability of EC embryos in comparison to LC embryos after vitrification is unknown. The present study aims to investigate the post-vitrification de...

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...

Plasticity in life-history traits.

We describe the impact of recent life-history plasticity theory on insect studies, particularly on the interface between genetics and plasticity. We focus on the three-dimensional relationship between three key life-history traits: adult size (or mass), development time and growth rate, and the connections to life cycle regulation, host plant choice, and sexual selection in seasonal environment...
