  1. 16. An ecological investigation of spiders in coastal meadows : in Uppland and Sörmland

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Marie Langbak; [2022]
    Keywords : Spiders; coastal meadows; ecology; diversity; invertebrates;

    Abstract : Coastal meadows are important habitats for many animals, but the habitats are threatened by changes in land use such as abandonment of grazing. On the Swedish East coast, many coastal meadows can be found and they are highly influenced by the brackish marine environment which supports large populations of spiders. READ MORE

  3. 17. 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.

  4. 18. Peatland restoration: A mossy affair? : The similarities of the vegetation communitiesbetween restored bogs and natural bogs.

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Liesbeth van Ravenhorst; [2022]
    Keywords : Wetland; peatland; bog; vegetation composition; plant functional trait; environmental variable;

    Abstract : Peatlands function as important global carbon sinks as peatlands store 30% to 40% of the total soil carbon even though peatlands only cover 3% of the Earth's terrestrial surface. However, drainage activities have damaged the ecosystem and caused many peatlands to function as carbon sources instead. READ MORE

  5. 19. Using NDVI Time-Series to Examine Post-fire Vegetation Recovery in California

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Viktor Wu; [2022]
    Keywords : fire; California; NDVI; land cover; vegetation; post-fire recovery;

    Abstract : Over the past couple of decades, fires have experienced changes on a global scale. These changing fire regimes point to an alarming direction where fire-dependent ecosystems are experiencing a decline in burned area, while fire-independent ecosystems are experiencing an increase.

  6. 20. Could horse grazing be used to restore abandoned fields? : a comparison of the vegetation between horse pastures and abandoned fields, and an inventory of the effects of grazing- history and intensity

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

    Author : Jantien Vogel; [2022]
    Keywords : abandoned field; grazing; horse pasture; functional traits; species richness; vegetation;

    Abstract : Semi-natural fields, created by traditional land-use systems like low-intensity cattle grazing, have high ecological value due to the occurrence of numerous plant species, and their associated faunal communities. In Sweden, this habitat is threatened by both land-abandonment and agricultural intensification. READ MORE
