1. Sex-associated genomic variation in two ecotypes of Littorina saxatilis on the Swedish west coast
University essay from Göteborgs universitet/Institutionen för marina vetenskaperAbstract : Sex, one of the most conspicuous characteristics of living organisms, has always been fascinating for biologists. The diversity of sex goes much beyond a simple distinction between males and females. Many organisms have more than two mating entities, and many species show some degree of hermaphroditism, at least in part of their life cycle. READ MORE

2. Spatiotemporal variation in the relative fitness of a northern and a southern ecotype of Arabidopsis thaliana
University essay from Uppsala universitet/Institutionen för biologisk grundutbildningAbstract : Terrestrial plants exist in almost every habitat on the earth, ranging from warm and moist tropical rainforests, hot and dry deserts, and to cold and barren tundras. Furthermore, a single species may encounter different climatic conditionshabitats within its range distribution which climatic conditions differs from one to another. READ MORE

3. Impact of plant ecotype on Bacillus-mediated growth promotion : extending beyond the standard model plant
University essay from SLU/Dept. Of Plant BiologyAbstract : This study investigated how bacterial treatment modulates plant growth. Bacillus amyloliquefaciens UCMB5113 was used for treatment of several different natural accessions (ecotypes) as well as mutants of Arabidopsis thaliana. Treatment effect on plant root architecture was studied in particular. READ MORE

4. How two different predators affect size distribution and behavior of an aquatic isopod
University essay from Institutionen för fysik, kemi och biologiAbstract : The aquatic isopod Asellus aquaticus can in some lakes be found as two different ecotypes; one in the habitat dominated by reed and one in stonewort stands. These ecotypes have been shown to differ in size, color and behavior. The reed ecotype is larger, darker and more active compared to the stonewort ecotype. READ MORE

5. Potassium channel AtTPK5 : An essential or redundant regulator of photosynthesis in Arabidopsis?
University essay from Institutionen för fysik, kemi och biologiAbstract : It has previously been stated that K+-ions in a plant cell have a counter-balancing role in which the efflux of K+-ions from the thylakoid lumen charge-balance the light-induced proton pumping that is known to occur across the thylakoid membrane, and this in turn stabilizes photosynthetic activity. In the present study, two different types of plants of the same ecotype (Col-0) of Arabidopsis thaliana have been studied: a wild-type and a T-DNA exon-mutant (tpk5-e) that has lost the expression of the protein known as Tandem-pore K+- channel (AtTPK5).
