Sexual selection and speciation in field crickets.
Recent theoretical work has shown that sexual selection may cause speciation under a much wider range of conditions than previously supposed. There are, however, no empirical studies capable of simultaneously evaluating several key predictions that contrast this with other speciation models. We present data on male pulse rates and female phonotactic responses to pulse rates for the field cricke...
متن کاملMolecular divergence between Gryllus rubens and Gryllus texensis, sister species of field crickets (Orthoptera: Gryllidae)
We assess the degree of sequence divergence in the maternally inherited mitochondrial cytochrome c oxidase I (COI) and cytochrome b (CytB) genes between two sister species of field crickets, Gryllus rubens Scudder, 1902 and Gryllus texensis Cade and Otte, 2000. We analyzed 1460 base pairs from 10 individuals of each species; individuals were sampled from areas of both allopatry and sympatry. Ov...

Diet, sex, and death in field crickets
Senescence is shaped by age-dependent trade-offs between fitness components. Because males and females invest different resources in reproduction, the trade-offs behind age-dependent reproductive effort should be resolved differently in the sexes. In this study, we assess the effects of diet (high carbohydrate and low protein vs. equal carbohydrate and protein) and mating (once mated vs. virgin...
متن کاملDemography and mating system shape the genome-wide impact of purifying selection in Arabis alpina.
Plant mating systems have profound effects on levels and structuring of genetic variation and can affect the impact of natural selection. Although theory predicts that intermediate outcrossing rates may allow plants to prevent accumulation of deleterious alleles, few studies have empirically tested this prediction using genomic data. Here, we study the effect of mating system on purifying selec...
