Sexual Dimorphism and Consequences of Sex-Specific Selection in Drosophila melanogaster
… phenotypic differences, largely caused by sex-biased geneexpression. Most of this sexual dimorphism is thought to arise because selection favours divergent phenotypes in the sexes. With Drosophila melanogaster as the study organism, my thesis takes several approaches to investigate sexual …

TROPHIC ECOLOGY OF SAILFISH LARVAE IN THE GULF OF MEXICO: AN ANALYSIS OF DIET, PREY AVAILABILITY, PREY QUALITY, AND INFLUENCES ON LARVAL GROWTH
… Sailfish larvae showed significant positive selection for <em>Evadne</em> and female <em>Farranula.</em> To examine quality of preferred prey and condition of sailfish larvae, fatty acid concentrations were examined as fatty acid methyl esters. Results indicated that total fatty acid …

Sisters' curse: sexually antagonistic selection constrains the spread of a rare mitochondrial haplogroup
… the evolution of divergent mating tactics in the sexes. In most species, anisogamy is also coupled with strict maternal inheritance of genetic elements in the cytoplasm, including DNA in cellular endosymbionts and mitochondria. Because males are an evolutionary dead end for mitochondria, mutations …

Genetic modification of the homomorphic sex chromosomes in the yellow fever mosquito Aedes aegypti provides novel insights and tools for biocontrol
… transmit pathogens, efficient and accurate sex separation of the non-biting males from the biting females is essential. Genetic sexing strains often rely on marker genes linked to the sex chromosomes. Sex linkage is more challenging in Ae. aegypti than many other species due to the …

Sex Differences in Direct Aggression: The Role of Impulsivity, Target Sex, and Intimacy with the Target
Men are, as a sex, more aggressive than women. Evolutionary accounts of the sex difference in direct aggression focus on the differing costs and benefits of aggression for men and women, and posit that male aggression and female non-aggression are both part of a suite of adaptations to sex-specific …
