Sex in southern african spirostreptida millipedes : mechanisms of sperm competition and cryptic female choice
… at the gametic level via sperm competition and cryptic female choice. By combining studies of genital form and function with single and double mating experiments, this study elucidates these processes in some southern African Spirostreptida millipedes.

Mating dynamics of South African forest millipedes : Centrobolus (Diplopoda: Pachybolidae)
… of sexual selection, sperm competition and cryptic female choice. The approach was to (1) quantify sexual dimorphism and find the selection pressures operating on the sexes, (2) determine the functional significance of male and female genitalia, (3) understand why there should be a conflict …

Mechanisms and consequences of hybridisation between Atlantic salmon (Salmo salar) and brown trout (Salmo trutta)
… competition. This is the first evidence for cryptic female choice via a reproductive fluid in an external fertiliser. The second objective of my thesis was to investigate the potential consequences of salmon-trout hybridisation for wild populations. This was achieved through comparing the …

Function and evolution of seminal fluid components in Drosophila
… the male reproductive tract are transferred to females during mating and induce profound female post-mating behavioral and physiological shifts. Many SFPs work in concert with female-derived molecules to promote fertility. However, reproductive fluids are a battleground for evolutionary …

PRE- AND POST-COPULATORY SEXUAL SELECTION IN THE TORTOISE BEETLE ACROMIS SPARSA (COLEOPTERA: CHRYSOMELIDAE)
<p>Females in nearly all sexually reproducing taxa mate with multiple males. In these species, male fitness is dependent on traits used during both the pre-copulatory processes influencing mate acquisition, as well as the post-copulatory processes influencing fertilization. However, few studies …
