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. A computational model of metapopulation dynamics and organism-mediated nutrient flow

   University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

   Author : Amanda Hansson; [2023-08-07]
   Keywords : computational model; population dynamics; metapopulation dynamics; nutrient flow; simulation; spatially explicit; individual-based;

   Abstract : The aim of this project was to assess, using in-silico experiments, how different life history char-acteristics, such as age at maturity and dispersal ability of individuals, influence the dynamics of a metapopulation. To achieve this, a novel model of a spatially explicit metapopulation, with organ-ism-mediated nutrient flow between fragmented habitat patches, was implemented by means of computer simulations.

4. 3. Endosperm-based postzygotic hybridization barriers in Arabidopsis and Capsella

   University essay from SLU/Dept. Of Plant Biology

   Author : Mohammad Foteh Ali; [2021]
   Keywords : Endosperm development; Parental conflict; Genetic diversity; Auxin;

   Abstract : In Arabidopsis, endosperm development is very important for viable seed development. Especially, endosperm cellularization is a crucial event for embryo survival and if it fails, can lead to embryo arrest, as observed in seeds derived from interploidy and interspecies hybridization.

5. 4. Polyandry and genetic diversity in populations of Pholidoptera griseoaptera along an environmental gradient

   University essay from SLU/Dept. of Ecology

   Author : Matilda Jutzeler; [2019]
   Keywords : polyandry; genetic diversity; multiple mating; microsatellites; nuptial gift; phenotype;

   Abstract : Polyandry is a common mating pattern in different insect species and it leads to increased genetic diversity in the offspring and prevents inbreeding in populations. According to the theory of mate choice, mates should choose a partner that will increase heterozygosity in their offspring. READ MORE

6. 5. Reproductive patterns in the domesticdog : a retrospective study with theDrever breed as model

   University essay from SLU/Dept. of Clinical Sciences

   Author : Bojana Bobic Gavrilovic; [2007]
   Keywords : seasonality; age; parity; gestation length; litter size; sex ratio; male fertility;

   Abstract : Despite the long history of joint life between man and the dog (Canis familiaris), there are still many aspects of canine reproduction that are not well understood. Domestication of the dog from its ancestor the wolf is thought to have occurred at least 14 000 years agoIt is a unique situation that both the ancestor – the wolf, and the domesticated descendant - the dog, are still present world wide, which gives them a very important place in the fields of interest for scientific research.
