1. Color and wing size: identifying targets of sexual selection in Drosophila melanogaster
Kandidat-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Sammanfattning : This study explores the relationship between wing size, coloration, and reproductivesuccess in Drosophila melanogaster, fruit flies. Sexual selection, a key aspect ofevolutionary biology, often involves visual signaling as a means of displaying geneticinformation. LÄS MER
2. Fitnesskomponenter hos honor av Drosophila melanogaster : Med alternativa alleler av en potentiell sexuellt antagonistisk gen
Kandidat-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Sammanfattning : Anisogami och sexuella konflikter kan vara grunden till flera fall av könslig dimorfism. Intralokus sexuell konflikt uppstår när alleler vid ett genetiskt lokus har en antagonistisk effekt på fitness hos hanar och honor. Helgenomstudier har pekat ut flera sexuellt antagonistiska kandidatgener hos Drosophila melanogaster. LÄS MER
3. Sexually segregated habitat selection in Daubenton’s bat Myotis daubentonii
Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental StudiesSammanfattning : Sexual segregation is a phenomenon present in many vertebrate taxa, including the bat order Chiroptera. Sexual segregation is a social and/or habitat separation based on sex and is driven by varying causes such as sexual dimorphism, resource and physiological limitations, predator avoidance and many other factors.

4. Sex differences in neuronal differentiation of human stem cells
Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildningSammanfattning : Sexual dimorphism has been long noted in human neurobiology, apparent most notably in sex-biased distribution of multiple neurological disorders or diseases, from autism spectrum disorder to Parkinson's disease. With the advances in molecular biology, genetics and epigenetics have come into focus as key players in sexually dimorphic neural development; and yet, many studies in the field of neuroscience overlook the importance of sex for the human brain.

5. Temperatur- och flödespåverkan på aspens (Leuciscus aspius) lekvandring i Fyrisån och Örsundaån, Uppland
Kandidat-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildningSammanfattning : Interconnected freshwater habitats are essential for many fish populations, which allow fish to migrate between areas to fulfil their life-cycle and maximize their fitness. Currently, such populations are negatively affected by human habitat exploitation. As a result, the biodiversity in freshwater ecosystems is decreasing. LÄS MER
