  1. 1. Physical microhabitat requirements for Margaritifera margaritifera and the influence of hydro- and morphodynamics on mussel bed stability

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Tove Westberg; [2020]
    Keywords : Stream restoration; Freshwater pearl mussel; Microhabitat requirements; Sediment transport; Mussel translocation;

    Abstract : Margaritifera margaritifera is an endangered freshwater pearl mussel with population declines throughout its Holarctic range. Boulder-bed channels with little input of fine sediment in previously channelized streams are abundant in Sweden. Hence, restoration efforts for M. READ MORE

Det gör att vattendraget inte lever upp till kravet på god ekologisk status i EU:s ramdirektiv för vatten. READ MORE

  3. 3. Is it possible to define different process domains in stream systems based on remote data? : Comparing surficial geology, geomorphological characteristics in the landscape and channel slope between lakes, rapids and slow-flowing reaches.

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Elin Åberg; [2019]
    Keywords : Process domains; Lakes; Slow-flowing reaches; Rapids; GIS; Slope; Surficial geology; Geomorphological characteristics in the landscape;

    Abstract : Restoration of stream channels have become a common way of trying to restore both the channels and the ecosystems that earlier have been channelized mainly to facilitate the movement of timber. According to previous studies a lot of the restoration has been performed without a sufficiently detailed plan and with too little focus on how the landscape interplay with the restoration, which makes the potential to learn from possible mistakes minimal.

  4. 4. The effect of riparian buffer properties on spider communities and aquatic-terrestrial food-web lingages : using polyunsaturated fatty acids as biomarkers

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Ellinor Ramberg; [2019]
    Keywords : riparian buffer; polyunsaturated fatty acids; spiders; trophic connectivity; subsidies; agricultural landscape;

    Abstract : Riparian habitats are key habitat interfaces that regulate flows of resource subsidies between aquatic and terrestrial food webs, whilst supporting high biodiversity andproviding ecosystem services. However, frequently these habitats are highly degraded, especially in agricultural landscapes. READ MORE

  5. 5. En fristad? : asylsökandes perspektiv på utemiljön vid boende

    University essay from SLU/Department of Work Science, Business Economics, and Environmental Psychology

    Keywords : Flyktingförläggning; asylboende; utemiljö; trädgårdskultur;

    Abstract : Under de senaste åren har vi sett en strid flyktingström komma till Sverige. Människor placeras i stora boenden som i vissa fall är utdömda för annan verksamhet. Fokus har legat på att få in många personer på liten yta och få allt det praktiska att fungera. Utemiljöns utformning har det inte funnits kunskap, tid eller pengar till. READ MORE
