  1. 1. The Origins and Ecology of Early Paleozoic Spreiten Ichnofossils: Comparisons of Daedalus and Syringomorpha with Alectorurus

    Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Zane Goodell; [2023]
    Nyckelord :trace fossils; ichnology; Cambrian; Daedalus desglandi; Alectorurus circinatus; Syringomorpha nilssoni; the agronomic revolution;

    Sammanfattning : The Cambrian explosion not only shaped the ecosystems of the Phanerozoic, but fundamentally changed how biota interacts with the environment, including the substrate. Cambrian trace fossils Alectorurus and Syringomorpha as well as Ordovician-Silurian Daedalus represent novel modes of faunal interaction with the newly innovated shallow marine mixed-ground and have surprisingly limited stratigraphic ranges.

  4. 3. Sustainability Transitions Antenarratives: Public Sector Organization Perspectives in Implementing Sustainability Oriented Projects in a Developing Country

    Magister-uppsats, Malmö universitet/Institutionen för Urbana Studier (US)

    Författare :Kamwasir Kamwasir; [2022]
    Nyckelord :Sustainability; Sustainability transition; public sector organizations; multi-level perspective; niches; micro-niches;

    Sammanfattning : Sustainability has been considered a novel research field emerging from the desire to protect the environment, and equally emerging in transition discourses. This research explores the construction of sustainability transition processes and pathways in a public sector organization implementing a sustainability oriented program. LÄS MER

  5. 4. How Does Intraspecific Trait Variation Influence the Climate Niche Breadth of Tropical Tree Species?

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Helene Hansen; [2022]
    Nyckelord :intraspecific variation; niche breadth; plants;

    Sammanfattning : With the contribution of intraspecific trait variation (ITV) to ecological processes being increasingly appreciated, its role in defining niche characteristics arises as a topic of interest. I hypothesised that species with a high magnitude of ITV would occupy a larger climate niche breadth than species with little ITV.

  7. 5. Diversification of predators in multi-trophic communities: A trait-based theoretical approach

    Master-uppsats, Lunds universitet/Examensarbeten i bioinformatik

    Författare :Julio Antonio Ayala Lopez; [2022]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : 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. LÄS MER
