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

    University essay from SLU/Dept. 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.

  3. 37. How do stand composition and cervid densities influence the forest floor vegetation in a multi-cervid species context?

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Clémentine Leemans; [2021]
    Keywords : alces; cerus elaphus; dama; capreolus; cervid; vaccinium; myrtillus; pinus sylvestris; picea abies; browsing; forest floor cover;

    Abstract : The cover of forest floor vascular plants has been decreasing in Sweden over recent decades. Cervid rely heavily on this vegetation for food. With this study, I showed that habitat type highly influences the quality and quantity of the forest floor vegetation. READ MORE

  4. 38. Testing the potential to evaluate vegetation optical depth with ecosystem water dynamics in a temperate forest

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Ainahu Abdul Hamid; [2021]
    Keywords : Physical geography; Ecosystem analysis; Vegetation optical depth; Temperate Forest; Climate; LPJ-GUESS; Evapotranspiration; Leaf water potential; Isohydricity; Hydraulic failure; Carbon starvation; Earth and Environmental Sciences;

    Abstract : Warming trends have been associated with drought which induces and heightens agents and factors that cause tree mortality. Remotely sensed observations are increasingly being used in vegetation studies and are obtained from Earth observation satellites. READ MORE

  5. 39. Predicting forest strata from point clouds using geometric deep learning

    University essay from Jönköping University/JTH, Avdelningen för datavetenskap

    Author : Simon Arvidsson; Marcus Gullstrand; [2021]
    Keywords : Supervised learning; Learning to rank; Point-based models; Shape inference; PointNet; layering; layers; classification; ordingal; regression; forest agency; ranking; SLU; 3D; plots;

    Abstract : Introduction: Number of strata (NoS) is an informative descriptor of forest structure and is therefore useful in forest management. Collection of NoS as well as other forest properties is performed by fieldworkers and could benefit from automation. READ MORE

  6. 40. Okonventionella grovfodermedel som krisfoder till nötkreatur

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Christine Alveblad; [2021]
    Keywords : foderbrist; grovfoder; skogsprodukter; vass; barrträd; lövträd; strategier;

    Abstract : Under torrperioder eller andra extrema väderförhållanden kan foderbrist uppstå. Detta skedde i Sverige år 2018 och lantbrukare blev tvungna att hitta andra vägar för att få fram foder till sina djur. Ett ökat intresse för okonventionella fodermedel så som vass och skogsprodukter har setts. READ MORE
