1. Effects of temperature and microplastic concentration on the consumption of microplastic particles by the detritivore Asellus aquaticus
Kandidat-uppsats, SLU/Dept. of Aquatic Sciences and AssessmentSammanfattning : 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. LÄS MER
2. Stickleback diets in bays along the northen Baltic Sea
Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : 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. LÄS MER
3. The effect of an anti-depressant on responses to predation in an isopod
Kandidat-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologiSammanfattning : 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. LÄS MER
4. Does Asellus aquaticus change its pigmentation when given different types of food?
Kandidat-uppsats, Linköpings universitet/BiologiSammanfattning : 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. LÄS MER
5. Hur påverkas kransalgen Chara globularis, vattengråsugga, Asellus aquaticus och påväxtalger av kalkning i en eutrof sjö?
Kandidat-uppsats, Linköpings universitet/BiologiSammanfattning : Grunda, näringsrika sjöar förekommer i två stadier: antingen ett med grumligt vatten och hög biomassa av växtplankton, eller ett med klart vatten och riklig undervattensvegetation. Det klara stadiet är eftersträvansvärt eftersom det skapar goda förutsättningar för en rad ekosystemtjänster, inklusive vattenkvalitet, rekreation och förutsättningar för biodiversitet. LÄS MER
