Publisher Summary To fully appreciate the impact of sperm storage on animal biology, it is
important to understand how animals deliver sperm to storage locations, how they maintain …

One hundred years after Darwin considered how sexual selection shapes the behavioral
and morphological characteristics of males for acquiring mates, Parker realized that sexual …

When females are inseminated by more than one male (polyandry) sexual selection
continues after insemination in the form of sperm competition and cryptic female choice. The …

Life scientists are increasingly drawn to the study of comparative evolutionary biology. Insect
Development and Evolution is the first synthesis of knowledge of insect development within …

Male reproductive success is dependent on insemination success and reproductive output.
During mating, male mosquitoes transfer not just sperm, but also seminal fluid proteins that …

1. In many organisms, males provide nutrients to females via ejaculates that can influence
female fecundity, longevity and mating behaviour. The effect of male mating history on male …

We have investigated the effects of experimental manipulation of copulation duration on
sperm displacement in Drosophila melanogaster. Both spermless and normal males were …

The central question addressed by most studies of sperm competition is:'what determines
which male's sperm are used at fertilization?'Empirical and theoretical studies that address …

Mating has been found to be costly for females of some species because of toxic products
that males transfer to females in their seminal fluid. Such mating costs seem paradoxical …

Abstract Male Callosobruchus maculatus F.(Coleoptera: Bruchidae) inseminate more sperm
than females can effectively store in their spermathecae. This study examines the adaptive …
