  • DNA metabarcoding reveals diet overlap between the endangered walia ibex and domestic goats - Implications for conservation 
    Mewicha, Berihun Gebremedhin; Flagstad, Øystein; Bekele, Afework; Gelete, Desalegn Chala; Bakkestuen, Vegar; Boessenkool, Sanne; Popp, Magnus; Gusarova, Galina; Schrøder-Nielsen, Audun; Nemomissa, Sileshi; Brochmann, Christian; Stenseth, Nils Christian; Epp, Laura (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)
    Human population expansion and associated degradation of the habitat of many wildlife species cause loss of biodiversity and species extinctions. The small Simen Mountains National Park in Ethiopia is one of the last ...
  • GIS as a tool for studying temporal and spatial patterns in Norwegian ecosystems across disciplines and scales 
    Bakkestuen, Vegar (Doctoral thesis / Doktoravhandling, 2009)
    As a starting point GIS (geographical information systems) seem intuitively to be a practical tool for biologists performing ecological research. GIS conveniently stores, explores, analyses and visualizes biological/ecol ...
  • Good-bye to tropical alpine plant giants under warmer climates? Loss of range and genetic diversity in Lobelia rhynchopetalum 
    Gelete, Desalegn Chala; Brochmann, Christian; Psomas, Achilleas; Ehrich, Dorothee; Gizaw, Abel; Masao, Catherine; Bakkestuen, Vegar; Zimmermann, Niklaus E (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)
    The main aim of this paper is to address consequences of climate warming on loss of habitat and genetic diversity in the enigmatic tropical alpine giant rosette plants using the Ethiopian endemic Lobelia rhynchopetalum as ...
  • Index Measuring Land Use Intensity—A Gradient‐Based Approach 
    Erikstad, Lars; Simensen, Trond; Bakkestuen, Vegar; Halvorsen, Rune (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    To monitor the changes in the landscape, and to relate these to ecological processes, we need robust and reproducible methods for quantifying the changes in landscape patterns. The main aim of this study is to present, ...
  • MIAT: Modular R-wrappers for flexible implementation of MaxEnt distribution modelling 
    Mazzoni, Sabrina; Halvorsen, Rune; Bakkestuen, Vegar (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
    The maximum entropy (MaxEnt) method has gained widespread use for distribution modelling, mostly because of the practical simplicity offered by the maxent.jar software. Whilst MaxEnt was originally described as a machine ...
  • Migration corridors for alpine plants among the `sky islands? of eastern Africa: do they, or did they exist? 
    Chala, Desalegn; Zimmermann, Niklaus E.; Brochmann, Christian; Bakkestuen, Vegar (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)
    The tropical alpine ecosystem in eastern Africa is highly fragmented among biological ‘sky islands’, where populations of frost-tolerant organisms are isolated from each other by a ‘sea’ of tropical lowlands. One-third of ...
  • Quest for new space for restricted range mammals: the case of the endangered Walia ibex 
    Gebremedhin, Berihun; Chala, Desalegn; Flagstad, Øystein; Bekele, Afework; Bakkestuen, Vegar; Van Moorter, Bram; Ficetola, Gentile Francesco; Zimmermann, Niklaus E.; Brochmann, Christian; Stenseth, Nils Christian (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    Populations of large mammals have declined at alarming rates, especially in areas with intensified land use where species can only persist in small habitat fragments. To support conservation planning, we developed habitat ...
