  1. 1. The effects of fishing on stability of a food web under climate warming

    University essay from SLU/Dept. Of Aquatic Resources

    Author : Gabriel Nordström; [2023]
    Keywords : fishing; climate change; temperature; predator; consumer; resource; stage-specific; food webs; ontogenetic assymetry; biomass overcompensation; emergent Allee effects; limit cycles;

    Abstract : Predicting the effects of fishing in a warmer environment caused by climate change requires knowledge of what trophic level is fished on, the physiological effects of temperature on fish, and how these two affect ecological interactions. Both temperature and fishing are known to affect the stability of food webs in several ways. READ MORE

  3. 2. 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

  4. 3. Diversification of predators in multi-trophic communities: A trait-based theoretical approach

    University essay from Lunds universitet/Examensarbeten i bioinformatik

    Author : Julio Antonio Ayala Lopez; [2022]
    Keywords : Biology and Life Sciences;

    Abstract : One of the main challenges in ecology and evolutionary biology is to understand how biodiversity emerges and is maintained, given the complexity of ecological and evolutionary processes combined. Understanding how multi-trophic interactions occur from a theoretical perspective is highly relevant for our understanding of diversification in complex ecosystems. READ MORE

  5. 4. Tree origin or traits? : what makes a tree suitable as an urban habitat for insect fauna?

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Kalle Ågren; [2022]
    Keywords : Biodiversity; Tree morphology; Invertebrates; Natives; Non-natives; Geographical origin; Phylogeny; Exotic; Plant technology; Congeners; Urban;

    Abstract : A global decline in diversity of plants and animals, has led to an increased focus on the topic of biodiversity. The trend of urbanisation can be a facilitator for biodiversity loss, and cities generally have lower densities of species compared to non-urban areas. This has made biodiversity in cities an important concept. READ MORE

  6. 5. Quantifying the state of the coral reef ecosystem in relation to biophysical benthic and pelagic indicators and biological drivers of change in the Saba National Marine Park, Dutch Caribbean

    University essay from SLU/Dept. Of Aquatic Resources

    Author : Wiebke Homes; [2021]
    Keywords : GCRMN; Reef Health Index; ; marine protected area; fish-benthos interaction; macroalgae; herbuvory; trophic cascade; fishing; coral disease; Caribbean;

    Abstract : Coral reefs are experiencing large scale degradation. Motivated by the need for regular data monitoring and for quantification of the state and change of benthic and pelagic organisms, the Global Coral Reef Monitoring Network protocol was executed on 18 dive sites in fished and unfished areas around the island of Saba in the Saba National Marine Park (SNMP) in the Dutch Caribbean from March to May 2019.
