2. 1. Benthic invertebrate food webs in the Baltic Sea : Anthropogenic pressure effects and methodological advancements

   Author : Julie Garrison; Francisco Nascimento; Ángel Borja; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; food web; trophic network; detritivore; Baltic Sea; macrofauna; marinbiologi; Marine Biology;

   Abstract : Trophic interactions are ecologically important, as they structure communities, and globally important for the ecosystem functions that they facilitate. Anthropogenic pressures are altering the structure of food webs, their stability, and resilience to change. READ MORE

4. 2. The importance of biodiversity for ecosystem processes in sediments : experimental examples from the Baltic Sea

   Author : Johan Näslund; Jonas Gunnarsson; Sara Sjöling; Nils Kautsky; Antoine Grémare; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biodiversity; Soft-bottom sediment; Ecosystem processes; Ecosystem function; Benthic-pelagic coupling; Baltic Sea; Trophic interactions; Pollutant biodegradation; Organic matter mineralization; Deposit feeder; Detritivore; Invasive species; Marine ecology; Marin ekologi; marin ekotoxikologi; Marine Ecotoxicology;

   Abstract : Aquatic sediments are, by surface, the largest habitat on Earth. A wide diversity of organisms inhabit these sediments and by their actions they have a large influence on and also mediate many ecosystem processes. READ MORE

5. 3. Ecosystem functioning in streams : Disentangling the roles of biodiversity, stoichiometry, and anthropogenic drivers

   Abstract : What will happen to ecosystems if species continue to go extinct at the high rates seen today? Although ecosystems are often threatened by a myriad of physical or chemical stressors, recent evidence has suggested that the loss of species may have impacts on the functions and services of ecosystems that equal or exceed other major environmental disturbances. The underlying causes that link species diversity to ecosystem functioning include species niche complementarity, facilitative interactions, or selection effects, which cause process rates to be enhanced in more diverse communities.
