  1. 1. Waterfowl in temperate eutrophic lakes - Interactions with macroinvertebrates, submerged vegetation and fish

    University dissertation from Ola Marklund, Department of Ecology, Limnology, Lund University, 223 62, Lund

    Author : Ola Marklund; Lunds universitet.; Lund University.; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Hydrobiology; marine biology; aquatic ecology; limnology; Marinbiologi; limnologi; akvatisk ekologi; Chara; Asellus; chironomidae; ultraviolet radiation; epiphytes; predation; herbivory; diel vertical migration; fish; Waterfowl; macroinvertebrates; submerged vegetation;

    Abstract : Popular Abstract in Swedish I denna avhandling har jag fördjupat mig i de ekologiska sambanden mellan några av de mest påtagliga och kända organismerna i sjöar och dammar, nämligen sjöfåglar, undervattensväxter, smådjur (från och med nu kallade evertebrater, vilket betyder ryggradslösa djur), och i viss grad fisk. Bland sjöfåglarna (här avses främst änder, gäss, svanar och sothöns) finns det både växtätare, evertebratätare, fiskätare och allätare. READ MORE

  2. 2. Investigations of species richness effects on ecosystem functioning using stream-living macroinvertebrates as model organisms

    University dissertation from Ola Marklund, Department of Ecology, Limnology, Lund University, 223 62, Lund

    Author : Micael Jonsson; Umeå universitet.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; Species richness; species loss; process rates; ecosystem function; streams; macroinvertebrates; Ekologi; NATURAL SCIENCES Biology Terrestrial; freshwater and marine ecology; NATURVETENSKAP Biologi Terrestisk; limnisk och marin ekologi;

    Abstract : The work in this thesis deals with effects of changed species richness on process rates among stream-living macroinvertebrates. Global biodiversity is decreasing rapidly and it is poorly known what the consequences of this loss may be for ecosystems and the services they provide. READ MORE

  3. 3. Biodiversity and ecosystem functioning in created agricultural wetlands

    University dissertation from Lund University

    Author : Geraldine Thiere; Högskolan i Halmstad.; Lunds universitet.; Lund University.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Biology Terrestrial; freshwater and marine ecology; NATURVETENSKAP Biologi Terrestrisk; limnisk och marin ekologi; constructed ponds; eutrophication abatement; biodiversity conservation; functional diversity; macroinvertebrates; plants; bacterial denitrification; watershed scale; nitrogen removal; phosphorus retention;

    Abstract : Wetland creation at large, regional scales is implemented as a measure to abate the biodiversity loss in agricultural landscapes and the eutrophication of watersheds and coastal areas by non-point source nutrient pollution (mainly nitrogen). The consequences of creating many new wetlands for biodiversity conservation and nutrient retention (ecosystem functioning) in agricultural landscapes are still relatively unknown, both on local (per wetland) and regional (per landscape) scales.

  4. 4. Habitat compensation in nature-like fishways Effects on benthos and fish

    University dissertation from Karlstad : Karlstads universitet

    Author : Stina Gustafsson; Karlstads universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biocanal; biodiversity; brown trout; freshwater pearl mussel; functional feeding groups; habitat heterogeneity; large woody debris; macroinvertebrates; PIT-tag; salmonids; Biology; Biologi;

    Abstract : The construction of nature-like fishways has become an increasingly common measure to restore longitudinal connectivity in streams and rivers affected by hydroelectric development. These fishways also have the potential to function as habitat compensation measures when running waters have been degraded or lost. READ MORE

  5. 5. The Macroinvertebrate Community in a Nature-like Fishway with Habitat Compensation Properties

    University dissertation from Karlstads universitet

    Author : Stina Gustafsson; Karlstads universitet.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nature-like fishway; biodiversity; macroinvertebrates; functional feeding groups; Biology; Biologi;

    Abstract : Nature-like fishways are often constructed to restore connectivity in streams exploited for hydropower. They also have the potential to compensate for important habitats that have been degraded or lost. READ MORE
