1. Cryptic Female Choice and Male Mating Behaviour : Sexual Interactions in Beetles
Sammanfattning : The importance of cryptic female choice, i.e. female post-copulatory influence over male reproductive success, in driving the evolution of male traits remains controversial. The main aim of this thesis was to understand the post-copulatory consequences of sexual interactions and the importance of cryptic female choice in two species of beetle. LÄS MER
2. Choice, competition, and interactions between episodes of sexual selection
Sammanfattning : Choice and competition are essential parts of evolutionary biology. In an effort to pass their genes from one generation to the next, animals may carefully choose their mating partners, and/or compete for access to mates. LÄS MER
3. Sexual conflict and male-female coevolution in the fruit fly
Sammanfattning : Harmony and cooperation was for long believed to dominate sexual interactions. This view slowly started to change 25 years ago and is today replaced with a view where males and females act based on what is best from a costs-benefits perspective. LÄS MER
4. Pre- and post-copulatory sexual selection in the fowl, Gallus gallus
Sammanfattning : The evolutionary goal of individuals is reproduction and sexual selection favours traits improving reproductive success. When males invest less than females in offspring, males have potentially a higher reproductive rate than females. LÄS MER
5. Resources, the environment, and sex : Examining variation in sexually selected traits in a livebearing fish
Sammanfattning : Striking variation is observed in sexually selected traits. These traits influence the outcome of competition and choice before and after mating. Before mating, animals compete for the access to mating partners and choose who to mate with between several potential mates. LÄS MER
