Genom sin aktivitet med dammbygge och trädfällning skapar bävern produktiva våtmarker med hög diversitet. Man har funnit att vid bäverns dammkonstruktion var artantalet närmare dubbelt så stort jämfört med i dammen och i det rinnande vattne

The colour choice of spiders and the effects of competition on this phenomenon were examined in the laboratory using the sit-and-wait predator goldenrod crab spider (Misumena vatia, (Thomisidae)). This species can be both white and yellow (could also

Effects of fishery closure on perch was detected as female perch was on average 5 cm longer in closed areas compared to non-closed areas. This could be a result of larger individuals surviving as an effect of reduced fishing. No effect was detected o

The climate affects animal populations through several processes. These processes includereproduction, phenology and the success of hunting. By influencing the phenology of species theclimate also affects the way species interact. If a climate-induce

Cross-boundary movements of energy and material are ubiquitous. Freshwater ecosystems receive nutrients, dissolved, and particulate organic matter from adjacent terrestrial ecosystems, whereas terrestrial ecosystems mainly receive prey organisms and

Some of the major problems we face today are human induced changes to the nitrogen (N), phosphorus (P) and carbon (C) cycles. Predicted increases in rainfall and temperature due to climate change, may also increase dissolved organic matter (DOM) infl

This research aims to investigate the effects that dredging may have on benthic fauna. The dredging took place in the stream Ireån on northern Gotland during the early summer 2010. My area of research was taking place in a scenic area downstream in

Våtmarker som anläggs på jordbruksmark kan förhindra att fosfor från åkrarna når sjöar och vattendrag och hjälper därmed till att minska övergödningen. Det är viktigt att utforma våt-marken på ett sådant sätt att så mycket som möjl
