  1. 1. Are the differences in the stringency of domestic environmental regulations affecting the bilateral trade of OECD countries?

    University essay from Handelshögskolan i Stockholm/Institutionen för nationalekonomi

    Author : Lishu Zhang; [2019]
    Keywords : Bilateral trade; Environmental regulation; Energy intensity; Gravity model; Panel data;

    Abstract : The question of whether the stringency of domestic environmental regulations indeed interferes with trade is of growing interest for better policymaking. This paper re-examines the relationship between the stringency of environmental regulations and bilateral trade using a panel dataset consisting of 34 OECD countries over 7 years. READ MORE

  2. 2. Investigation of the role of insulin receptor genes in wing polyphenism using gene knockdown and differential gene expression analysis in the non-model organism Gerris buenoi

    University essay from Uppsala universitet/Institutionen för ekologi och genetik

    Author : Sofia Iggström; [2019]
    Keywords : Phenotypic plasticity; RNAi; RT-qPCR; wing polyphenism; water striders;

    Abstract : Wing polyphenism is a type of phenotypic plasticity present in several insect species whereby a genotype have the ability to develop alternative wing morphs when exposed to different environmental cues. One organism demonstrating a clear case of wing polyphenism is the water strider species, Gerris buenoi, which develop long- or short wings depending on exposure to different photoperiods (the time the organism is exposed to light during a 24 h period).

  3. 3. Importance of fish community structure, nutrients and browning for shallow lake ecosystem dynamics : A modelling perspective

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Ylva Karlberg; [2019]
    Keywords : biological modelling; bowning; food webs; trophic interactions; top-down and bottom-up control; nutrients; light; shallow lake; biologisk modellering; brunifiering; födovävar; trofiska interaktioner; näring; ljus; grund sjö;

    Abstract : In a changing climate, it is increasingly important to be able to model environmental effects on food webs, and to do that, one must have appropriate dynamic models. I present a shallow lake ecosystem model where producers, grazers, carnivores, piscivores, and detritivores are coupled through resource (light, nutrients and detritus) fluxes between the benthic and pelagic habitats and through carnivore life history events (ontogenetic habitat and diet shifts).

  4. 4. To be, or not to be, organic : Motives and barriers for Swedish wine farmers to use organic practices

    University essay from Uppsala universitet/Företagsekonomiska institutionen; Uppsala universitet/Företagsekonomiska institutionen

    Author : Andreas Länn; Philip Wikholm; [2019]
    Keywords : Organic farming; Viticulture; Wine; Organic wine; Self-determination theory; Motivation; Swedish wine;

    Abstract : Wine production is one of the farming practices with the highest negative environmental impacts, mainly due to a heavy use of pesticides, why it is important to find more sustainable wine production practices. One such practice is organic farming, but the transition is slow and the number of organic certified vineyards remain low. READ MORE

  5. 5. Sustainable Drainage Systems Assessment and Optimisation-A case study for Lussebäcken Catchment, Helsingborg

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Bernard Nsabimana; Néstor Utande Estallo; [2019]
    Keywords : Hydraulics; hydrology; Sustainable Drainage Systems; urban; Modeling; MIKE URBAN; Technology and Engineering;

    Abstract : Increase of urbanization and climate change are one of the factors that have been highlighted to influence hydrography. This is resulting in an increase in peak flow within an urban watershed. Downstream flooding and increased pollution are the problems that arises. READ MORE
