  2. 1. Ecology across Boundaries : Food web coupling among and within ecosystems

    Author : Pia Bartels; Peter Eklöv; Lars J. Tranvik; Daniel E. Schindler; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; cross-ecosystem; food web; habitat coupling; terrestrial-aquatic linkages; subsidy; allochthonous; lake ecosystem; population divergence; trait variation; Terrestrial; freshwater and marine ecology; Terrestrisk; limnisk och marin ekologi; Freshwater ecology; Limnisk ekologi; Biology; Biologi; Biologi med inriktning mot limnologi; Biology with specialization in Limnology;

    Abstract : 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 detritus deposited by physical processes such as floods from freshwater ecosystems.

  4. 2. Benthic-pelagic coupling in a changing world : Structural and functional responses of microbenthic communities to organic matter settling

    Author : Séréna Albert; Francisco J. A. Nascimento; Monika Winder; Stefano Bonaglia; Tom Moens; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Soft sediments; benthic-pelagic coupling; organic matter export; meiofauna; nitrogen cycle; metabarcoding; Baltic Sea; Marine Ecology; marin ekologi;

    Abstract : Marine soft sediments form the second largest habitat on the planet. Organisms residing in this environment represent a vast reservoir of biodiversity, and play key roles in ecosystem processes. READ MORE

  5. 3. The influence of trophic polymorphisms on habitat coupling in aquatic food webs

    Author : Maria H. K. Marklund; Peter Eklöv; R. Svanbäck; Pierre Magnan; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology with specialization in Limnology; Biologi med inriktning mot limnologi;

    Abstract : Trophic cascades, together with other indirect interactions are important aspects in shaping the composition and abundance of species in the food web. Theoretically, movement of energy between systems, and coupling between habitats by mobile predators have been suggested as being important for food web stability and evenness. READ MORE

  6. 4. Importance of blue mussels for biodiversity and ecosystem functioning in subtidal habitats

    Author : Pia Norling; Nils Kautsky; Tom Ysebaert; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; blue mussel; Mytilus spp.; ecosystem engineering; habitat-modifier; diversity; facilitation; ecosystem functioning; ecosystem services and water quality maintenance; Marine ecology; Marin ekologi; marin ekotoxikologi; Marine Ecotoxicology;

    Abstract : Blue mussels, Mytilus spp., occur on rocky and sedimentary shores worldwide where they often form dense aggregates. These assemblages change the local environment and create unique habitats. READ MORE

  7. 5. Biomass patterns in boreal-subarctic lake food webs along gradients of light and nutrients

    Author : Gustaf Thomsson; Sebastian Diehl; Dag Olav Hessen; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; boreal-subartic lake; cDOM; epilithon; benthic-pelagic coupling; carnivores;

    Abstract : There is large natural variation in light and nutrient conditions across lakes. In the boreal-subarctic region most lakes are small, shallow and nutrient poor. In such lakes there is often sufficient light to support primary production at the lake bottom. READ MORE
