1. Effects of temperature and microplastic concentration on the consumption of microplastic particles by the detritivore Asellus aquaticus
University essay from SLU/Dept. of Aquatic Sciences and AssessmentAbstract : Microplastic (MP) pollution has now reached a point where particles can be found in every environmental compartment across the globe. However, the ecological and long-term consequences of MPs are largely unknown. READ MORE

2. Stickleback diets in bays along the northen Baltic Sea
University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskapAbstract : Coastal populations of perch (Perca fluviatilis) in the Baltic Sea has declined substantially the last decades while the populations of three-spined sticklebacks (Gasterosteus aculeatus) has increased rapidly during the same time period. Earlier studies have suggested that predation on perch larvae and or competition from sticklebacks are the causes behind the decline in perch. READ MORE

3. The effect of an anti-depressant on responses to predation in an isopod
University essay from Linköpings universitet/Institutionen för fysik, kemi och biologiAbstract : A lot of chemicals and pharmaceutical substances used by humans, are released into the waste-water and end up in lakes and ponds. Further, because pharmaceutical substances are increasing worldwide, the problem increases. A very common human anti-depressant is fluoxetine which is found in lakes, ponds and even in the bodies of aquatic organisms. READ MORE

4. Does Asellus aquaticus change its pigmentation when given different types of food?
University essay from Linköpings universitet/BiologiAbstract : When an animal’s pigmentation matches the background across various types of environments, it is potentially an example of cryptic pigmentation, most likely as a response to natural selection by visually oriented predators. One example of cryptic pigmentation is phenotypic plasticity, meaning that an organism can exhibit different phenotypes in different environments. READ MORE

5. Effects of diet quality and quantity on resource use, growth and fatty-acid composition of a benthic generalist consumer.
University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskapAbstract : Variation in quality and quantity of food resources can affect consumer productivity responses throughout the food chain, particularly the efficiency at which basal resources are converted to consumer biomass. I performed a manipulative feeding experiment to investigate the somatic growth and fatty acid incorporation in the benthic generalist isopod Asellus aquaticus, in response to differing ratios of autochthonous (high quality algae) to allochthonous (low quality leaf litter) foods.
