  1. 16. Claws and Effect : how Small Carnivore Richness Responds to Habitat Diversity and Ecological Productivity

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

    Author : Emilia Arkdalen; [2023]
    Keywords : small carnivore; camera trap; occupancy model; species richness; productivity; habitat richness; habitat evenness;

    Abstract : Species distribution and composition research has gained significance in light of global warming and its impact on biodiversity. Understanding the factors shaping species richness is crucial for wildlife ecology and conservation. READ MORE

  3. 17. 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.

  4. 18. Multi-scale Bark Beetle Predictions Using Machine Learning

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Albert Øhrman Wellendorf; [2023]
    Keywords : Geography; GIS; Geographically weighted regression; bark beetle; machine learning; Earth and Environmental Sciences;

    Abstract : Bark beetle attacks have led to widespread tree disturbance and deaths in many parts of the world, and thereby also economic and biodiversity losses. Forest-rich Sweden has experienced periodic attacks, latest in 2018. READ MORE

  5. 19. Optimal foraging in an Arctic herbivore : How does the foraging behaviour of Svalbard reindeer (Rangifer tarandus platyrhynchus) respond to seasonal changes from summer through autumn of the Arctic tundra?

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

    Author : Emma Limosa Djurberg; [2023]
    Keywords : foraging behaviour; phenology; ungulate; Arctic; Rangifer tarandus platyrhynchus;

    Abstract : Foraging decisions of large herbivores can be affected by many factors and have great effect on both above- and below-ground ecosystems. Here, I determine to which degree temporal (seasonality), or spatial (habitat) factors influence the foraging behaviour of Svalbard reindeer (Rangifer tarandus platyrhynchus) and asses if small-scale foraging behaviour correlates with an animals’ patch residence time.

  6. 20. The diversity of moths in a nature reserve in the Northern Cape, South Africa : Variation over time, depending on abiotic factors and differences between areas with different grazing types

    University essay from Linnéuniversitetet/Institutionen för biologi och miljö (BOM)

    Author : Nellie Jarl; [2023]
    Keywords : Moth diversity; grazing effects; land use; biodiversity;

    Abstract : Land use changes globally have significant impacts on flora and fauna. In South Africa, extensive land is used for grazing by both domestic livestock and farmed native grazers. However, the effects of different grazing types on vegetation and fauna remain poorly understood. READ MORE
