  1. 1. Habitat use and activity patterns of three Eulemur species in the forest and restoration areas of Ranomafana and Ankafobe, Madagascar

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Nicole Scholte Lubberink; [2023]
    Nyckelord :fragmentation; anthropogenic deforestation; camera traps; occupancy modelling; detection probability;

    Sammanfattning : Anthropogenic deforestation is a major threat to forest environments, as it leads to habitat loss and fragmentation. Many species suffer from these consequences due to reduced resource availability or connectivity. Forests in Madagascar have drastically been reduced in the past few centuries. LÄS MER

  3. 2. Holocene vegetation change and its correlates in fennoscandia

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Raphaela Infanger; [2022-10-21]
    Nyckelord :Fennoscandia; Holocene; human impact; climate impact; vegetation change; fossil pollen;

    Sammanfattning : Climatic and anthropogenic legacy has differently impacted vegetation and its community composition. To determine the extent and origin of changes across Fennoscandia, representative regions were defined that entailed sufficient spatial and temporal data. LÄS MER

  4. 3. Examining the protective services of mangroves at a regional scale in Indonesia

    Master-uppsats, Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

    Författare :Mikaela Gomez; [2022]
    Nyckelord :Mangroves; Nature-Based Solutions; Disaster Risk Reduction; Exposure; GIS; Remote Sensing; Science General;

    Sammanfattning : The purpose of this thesis is to examine how the exposure of the coastal population of Kalimantan, Indonesia changed as a result of coastal mangrove loss and population growth. The change of exposure has therefore been calculated through the loss of mangrove biomass, through deforestation and degradation, over time, as well the increase in population living within 10km2 of disturbed mangroves.

  5. 4. Sumatranoshörningen (Dicerorhinus sumatrensis) på gränsen till utrotning - En riskanalys

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Amanda Gagné; [2021]
    Nyckelord :Sumatran rhinoceros; risk assessment; threats; conservation; Indonesia; Earth and Environmental Sciences;

    Sammanfattning : The critically endangered Sumatran rhinoceros (Dicerorhinus sumatrensis) has, due to previous hunting and habitat loss, diminished to a few non-viable and fragmented populations. Despite a relatively large amount of conservation efforts during the last 30 years, numbers are still declining. LÄS MER

  7. 5. Reconstruction of past European land cover from pollen data: using spatial statistics and Crank-Nicolson Monte Carlo

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Lovisa Svensson; [2019]
    Nyckelord :Pollen data; compositional data; Dirichlet distribution; spatio-temporal reconstruction; Kronecker product; Gaussian Markov random field GMRF ; Markov Chain Monte Carlo MCMC ; Metropolis Hastings MH ; Metropolis adjusted Langevin algorithm MALA ; Mathematics and Statistics;

    Sammanfattning : Given a pollen data set from Europe over a time period, the aim is to reconstruct the past land cover by interpolating from the pollen data values to a continuous map. The data is on compositional form with three vegetation categories; coniferous forest, broadleaved forest and open land. LÄS MER
