  1. 1. Global Warming Induced by Oceanic Anoxic Event 1a Had a Pronounced Impact on the Early Cretaceous Terrestrial Vegetation of Southern Sweden

    University essay from Uppsala universitet/Paleobiologi

    Author : Marcos Amores; [2022]
    Keywords : palynology; spore-pollen; biostratigraphy; oceanic anoxic event 1a; high-latitude; Early Cretaceous;

    Abstract : The Mesozoic is punctuated by several rapid global warming events that are marked by the worldwide deposition of organic-rich marine sediments. These events, known as oceanic anoxic events (OAEs), are characterised by intervals where the worldwide carbon cycle suffers a disruption due to major palaeoceanographic and climatic shifts, leading to anoxic marine environments and the creation of black shales.

  3. 2. Effects of climate warming on the performance of three boreal tree seedling species in interaction with moss cover and fire history

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

    Author : Maria-Theresa Jessen; [2017]
    Keywords : ;

    Abstract : Forest regeneration in the form of successful seedling establishment is a key factor for the persistence of a healthy forest ecosystem. Tree seedlings grow in a complex environment shaped by over- and understory and competition for light, nutrients and water. READ MORE

  4. 3. Trädsvampborrare i ettåriga tickor : betydelsen av värdsvamparnas släktskap och miljövariabler

    University essay from SLU/Dept. of Ecology

    Author : Sofia Lundell; [2017]
    Keywords : trädsvampborrare; Ciidae; tickor;

    Abstract : Trädsvampborrare (Ciidae) är en skalbaggsfamilj som lever i och är viktiga nedbrytare av vedlevande basidiesvampar, så kallade tickor. I en fältstudie har jag undersökt vilka arter av trädsvampborrare som lever i ettåriga tickor med frågeställningen om trädsvampborrarna i större utsträckning väljer närbesläktade värdsvampar än svampar som står långt ifrån varandra fylogenetiskt.

  5. 4. Linear movement and habitat boundary response by butterflies in power line corridors

    University essay from SLU/Dept. of Ecology

    Author : Axel Linder; [2017]
    Keywords : power line corridors; PLC; edge response; linear movement; butterflies; conservation; semi-natural grassland;

    Abstract : Sweden’s semi-natural grasslands and pastures have decreased radically during the 1900s, leading to a loss of butterfly populations and species associated with these habitats. Butterfly conservation efforts therefore should be concentrated towards finding suitable habitats that can either replace or support these lost habitats. READ MORE

  6. 5. Forest succession on abandoned agricultural land and its carbon stock

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Parisa Mazinanian; [2017]
    Keywords : forest succession; carbon stock; tree species; understorey vegetation; agricultural land abandonment; biomass; secondary forest; old-growth forest; soil carbon; carbon sequestration;

    Abstract : The development of secondary forest on abandoned agricultural lands has proven significant to land cover changes, especially in marginal areas across Europe. It is therefore important to quantify secondary forest succession in order to sustainably manage forest and agricultural resources, and also for modelling climate change. READ MORE
