  1. 1. Investigating the influence of the tidal regime on harbour porpoise Phocoena phocoena distribution in Mount’s Bay, Cornwall

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Duncan Jones; [2023]
    Keywords : Geography; Geographical Information Systems; GIS; Habitat Modelling; Harbour Porpoise; MaxEnt; Tidal Processes; Conservation; Earth and Environmental Sciences;

    Abstract : Investigating the influence of the tidal regime on harbour porpoise Phocoena phocoena distribution in Mount’s Bay, Cornwall Abstract Unintentional by-catch in fishing gear is a significant cause of mortality of harbour porpoises in UK waters. Understanding the spatial distribution of harbour porpoises at fine scales and how this changes over time is essential when trying to understand where these lethal interactions might occur.

  3. 2. A comparison of remote sensed semi-arid grassland vegetation anomalies detected using MODIS and Sentinel-3, with anomalies in ground-based eddy covariance flux measurements.

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Jason Craig Joubert; [2023]
    Keywords : Geography; GIS; Anomaly Detection; Remote Sensing; fAPAR; GDMP; GPP; MODIS; Sentinel-3; Earth and Environmental Sciences;

    Abstract : Remote sensed vegetation biophysical indicators are derived from various sensors and methods and contribute to the quantification of vegetation growth. They are used as inputs to early warning systems for crop yield estimation, thus improving crop management and food security. READ MORE

  4. 3. Modelling the growth of Pinus sylvestris L. monocultures in Sweden depending on the absorbed light

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Mateusz Grzeszkiewicz; [2022]
    Keywords : climate change; forest modelling; light use efficiency; photosynthetically active radiation; Scots pine;

    Abstract : Stand growth models are an important aid in contemporary sustainable forest management as a major planning and decision-making tool. However, climate change influencing growth conditions worldwide is a challenge to commonly used empirical models as they do not provide enough flexibility, which can result in inaccurate predictions and thus wrong decisions and sub-optimal results.

  5. 4. Starbursts at Cosmic Dawn : Formation of Globular Clusters, Ultra-Faint Dwarfs, and Population III star clusters at z > 6

    University essay from Stockholms universitet/Institutionen för astronomi

    Author : Olof Nebrin; [2022]
    Keywords : Cosmology; Galaxy Formation; Globular Clusters; First Stars; Dark Matter; Cosmic Dawn; Reionization; Ultra-Faint Dwarfs;

    Abstract : In the standard model of cosmology (ΛCDM) the first stars, star clusters, and galaxies are expected to have formed in short bursts of star formation in low-mass dark matter halos at high redshifts (). Up to this point, attempts to predict the properties and abundances of these luminous objects have made use of numerically expensive cosmological simulations. READ MORE

  6. 5. The impact of different evapotranspiration models in rainfall runoff modelling using HBV- light

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Oscar Maxander; [2021]
    Keywords : HBV-light; Rainfall runoff modelling; Evapotranspiration; Technology and Engineering;

    Abstract : The choice of which potential evapotranspiration (PET) model to use when estimating streamflow using a rainfall-runoff model have been the topic of many studies. The aim with this thesis was to assess the robustness of six different PET models using HBV-light as rainfall-runoff model over three catchments in Sweden. READ MORE
