  1. 1. Color and wing size: identifying targets of sexual selection in Drosophila melanogaster

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Ellen Pääjärvi Våg; [2024]
    Keywords : Sexual selection; wing interference patterns; Drosophila melanogaster; visual signaling; sexuell selektion; vingmönster; bananfluga; visuell signalering;

    Abstract : 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. READ MORE

  3. 2. Sexually segregated habitat selection in Daubenton’s bat Myotis daubentonii

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Esnart Emma Bwalya Chibwe; [2021]
    Keywords : sexual segregation; Daubenton’s bat; Myotis daubentonii; landscape analysis; habitat selection; foraging;

    Abstract : 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. 3. Sex differences in neuronal differentiation of human stem cells

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Olga Doszyn; [2019]
    Keywords : stem cells; neural stem cells; embryonic stem cells; sex differences; neuronal differentiation;

    Abstract : 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. 4. Sexual dimorphism in the migratory dynamics of a land-locked population of brown trout (Salmo trutta) in central Sweden : a study at three temporal scales

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Carl Vigren; [2018]
    Keywords : trout; salmonid; salmo; trutta; migration; upstream; Storsjon; Storsjön; Damman; Dammån; regulated; fish ladder; behaviour; protandry;

    Abstract : In this study I use a 56 years long dataset to study the migratory behaviours of a land-locked population of Brown trout (Salmo trutta) in the river Dammån, positioned in central Sweden. I found that there was a mean female-to-male sex ratio in the spawning-run of approximately 2.31 with an average 50% run date on the 29th of July. READ MORE

  6. 5. Age dependent costs of reproduction in a sexually dimorphic species : male fallow deer as an example

    University essay from SLU/Dept. of Ecology

    Author : Linn Lindström; [2017]
    Keywords : dama dama; cost of reproduction; home range size; sexual dimorphism;

    Abstract : Energy and time are two of the most important factors limiting the investment spent on reproduction for an organism. Due to this limitation, individuals have to balance between using energy for maintenance or growth and using it for reproduction. READ MORE
