  1. 1. Födovalspreferenser hos en arktisk specialist : vad föredrar Gynaephora groenlandica (Lepidoptera:Erebidae) att äta på Wrangelön?

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Beatrice Elfvenfjärd; Erika Åmansson; [2022]
    Keywords : Gynaephora groenlandica; arktisk ullbjörnslarv; födopreferenser; arktisk tundra; arktisk specialist; växtegenskaper;

    Abstract : The Arctic tundra has many unexplored areas. Due to the harsh climate and the difficult accessibility, there is a lack of knowledge about the different species that live under these circumstances. Herbivores in this environment have a large effect on the plant community, one of these is the moth butterfly larva Gynaephora groenlandica. READ MORE

  2. 2. Twenty-First Century Drought Projections in Swedish Catchments

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Elise Jonsson; [2022]
    Keywords : Drought; climate change; drought index; climate models; catchments; societal functions; Torka; klimatförändring; torkindex; klimatmodeller; avrinningsområde; samhällsfunktioner;

    Abstract : Droughts can have far-reaching and devastating effects on all sectors of society and ecology and future changes to drought and flood patterns are uncertain. This uncertainty has led to a lax response from local officials in dealing with mitigation and adaptation, particularly in Sweden. READ MORE

  3. 3. Parametric Studies of Train-Track-Bridge Interaction : An evaluation of the dynamic amplification due to track irregularities for freight transport

    University essay from KTH/Bro- och stålbyggnad

    Author : Rasmus Elm Dahlman; Emil Lundberg; [2021]
    Keywords : Dynamics; dynamic amplification factor; railway bridge; train-track-bridge interaction; vehicle model; track irregularities; PSD; Dynamisk förstoringsfaktor; dynamik; järnvägsbroar; tåg-spår-bro interaktion; fordonsmodell; spårojämnheter; PSD;

    Abstract : In this thesis a train-track-bridge interaction (TTBI) model is developed in order to study the dynamic amplification from track irregularities on railway bridges traversed by freight trains. These simulations are of great importance since rail freight transport is expected to increase in order to meet the climate goals. READ MORE

  4. 4. The intraspecific drought tolerance of Betula pendula Roth. : ecotypic aptitude as tree selection criteria for the urban landscape

    University essay from SLU/Department of Plant Breeding (from 130101)

    Author : Simon Hannus; [2021]
    Keywords : Betula pendula; clinal variation; drought tolerance; ecosystem services; ecotypes; potential evapotranspiration; turgor loss point; urban forestry; urban resilience; urban tree selection;

    Abstract : The ecosystem services provided by urban trees are substantial contributors to the quality of urban living, and their environmentally regulating capabilities are increasingly regarded as integral in order to efficiently secure urban resilience, by ameliorating the human and material impacts of extreme weather events. However, current trends of urban development presents challenges of how to preserve urban greenery ecosystem functioning, particularly in light of the ongoing climate change; which also has brought forth the importance of taxonomically diverse urban forests, to mitigate risks of catastrophic tree loss associated with these conditions.

  5. 5. Swedish wheat in the changing climate : screening for stable spring wheat genotypes from 2017 and 2018 with focus on protein quality for bread-making

    University essay from SLU/Department of Plant Breeding (from 130101)

    Author : Axel Belsing; [2021]
    Keywords : wheat; gluten protein; bread-making quality; stability; climate variation; breeding; SE-HPLC; micro-structure;

    Abstract : In recent years, wheat production and protein quality in wheat have been affected by climatic changes in Sweden and in many other parts of the world. Protein quality of wheat, determining the bread-making quality of flour, is a parameter sensitive to climate fluctuations and its stability has not been studied so far. READ MORE
