Changes in species richness and altitudinal distribution of vascular plants in Jotunheimen, Norway
Grindrud, Erlend Tandberg (Master thesis, 2019)Species richness was sampled on 254 sites distributed along the altitudinal gradient of 23 mountains in Jotunheimen, Norway. The sampling was conducted during the summer of 2014, on sites that previously had been sampled ... -
Comparing distribution of willow psyllids (Cacopsylla spp.) on Salix lapponum in 2018 with 1995 along an alpine altitudinal gradient
Selvig, Kristoffer (Master thesis, 2019)The psyllid (Cacopsylla spp.) population on Salix lapponum in the alpine areas of southern Norway, in an altitudinal gradient between Haugastøl and Finse, were thoroughly studied in 1995. The results were presented and ... -
Deteksjon av pionertrær i tregrenseøkotonen ved bruk av tredimensjonale punktskyer fra bildematching
Stensli, Steinar Gilleberg (Master thesis, 2019)Tregrenseøkotonen (overgangssonen mellom skog og treløst alpint område) har alltid vært i endring. I en periode med økning i gjennomsnittstemperatur og en endring i arealbruken, er tregrenseøkotonen forventet å etablere ... -
Effects of long-term experimental warming on alpine bryophytes : trends in functional traits
Dahle, Oda Sofie (Master thesis, 2019)Functional traits are becoming increasingly important tools to evaluate plant community response to climate change. Artificial warming treatments can shift community-level trait values as a consequence of intraspecific ... -
Effects of long-term experimental warming on fitness, morphology and species interactions of Silene acaulis
Rozite-Arina, Ieva (Master thesis, 2020)The global annual average surface temperature has increased significantly during the past century and is predicted to continue rising. Studies have shown that alpine ecosystems can be particularly sensitive to climate ... -
Effects of plant-plant interactions on the performance and abundance of Campanula uniflora in Dovre, Norway
Ekeland, Erlend (Master thesis, 2021)Anthropogenic environmental changes cause direct and indirect negative effects on alpine ecosystems. Human activities are accelerating the greenhouse effect and fragmenting and changing habitats. Increased temperature has ... -
Endret beitetrykk har effekter for planteegenskaper hos utvalgte boreale- og alpine arter : en etterundersøkelse etter 15 år langt beiteeksperiment
Straume, Lena (Master thesis, 2020)Beite er en viktig faktor som påvirker forekomst og egenskaper til mange plantearter. Denne studien er gjennomført som en etterstudie etter et 15 år langt beiteeksperiment med fravær av sau, lavt beitetrykk (25 sau per ... -
Krekling (Empetrum nigrum) sin påverknad på mortalitet og rekruttering på tre i tregrenseøkotonen
Hilstad, Inger Elisabeth (Master thesis, 2019)Klimaet er i endring, noko som vil påverka veksten, samansetninga og utbreiinga til vegetasjonen. Mange studiar har synt at det er i tregrenseøkotonen slike endringar vil vera tydelegast. Ulike studiar syner at krekling ... -
Long-term experimental warming in an alpine heath : decrease in cover of the most abundant bryophytes
Sundsbø, Snorre (Master thesis, 2019)Alpine ecosystems have shown to be sensitive to climate warming. Bryophytes are particularly important in alpine ecosystems and are known to support ecosystem services such as water regulation, nitrogen fixation and carbon ... -
Niche differentiation among boreal mammals and birds regarding their roles as endozoochorical seed dispersers
Liebe, Hauk (Master thesis, 2019)Plant seed dispersal by endozoochory (seed dispersal via the digestive system of animals) is an important process affecting plant species composition in ecosystems. Recent studies in temperate regions have shown that a ... -
Resilience of Alpine Salix shrubs to changes in browsing pressure
Palm, Marlene (Master thesis, 2020)Browsing by large herbivores has the potential to inhibit climate-driven shrub expansion. How resilient shrubs are to a change in herbivory, however, is not fully understood. In this study, I want to examine how Salix ... -
Seed rain and seedling emergence along hiking trails on elevation gradients in Dovre, central Norway
MacDougald, Aidan Cameron (Master thesis, 2020)Seed dispersal and seedling emergence represent critical events in the life history of plants and are fundamental agents in the formation of plant communities in time and space. Insight into the effects of human movement ... -
Short-term effects of Salix plantings and seeding of Festuca ovina on vegetation recovery in a disturbed alpine heathland in the Dovre Mountains, Norway
Vloon, Catharina Caspara (Master thesis, 2020)Alpine ecosystems are particularly vulnerable to anthropogenic disturbances and have a slow natural recovery rate. Open questions remain as to which forms of active restoration measures could accelerate alpine ecosystem ... -
The effect of long-term experimental warming on lichens and vascular plants in an alpine Dryas heath
Hasvik, Åshild (Master thesis, 2018)Global warming affects species diversity and ecosystems throughout the world, and alpine and arctic plant communities are considered to be particularly sensitive. During the last decades, several studies have shown a shift ... -
The Holocene vegetation history of an isolated, high-arctic plant diversity hot spot
Voldstad, Linn Margrethe Høeg (Master thesis, 2018)Through high throughput sequencing of ancient, environmental DNA collected from lake sediment cores (sedaDNA), this study revealed postglacial vegetation change during the last ~12.000 years in a high-Arctic plant diversity ... -
The influence of nest-site limitation on the species richness and abundance of bees : linking biodiversity and geology
Hanevik, Kaj-Andreas (Master thesis, 2018)There is mounting evidence of declines in global biodiversity. Declining wild bee populations are subject to concern because bees are considered the most important pollinators worldwide, contributing to the production of ... -
Tregrensedynamikk i Norge : endringer i treantall, mortalitet og vekst for pionærtrær langs en breddegradsgradient
Simensen, Kenneth Langlie (Master thesis, 2019)Økt kunnskap om endringer blant trærne i tregrensen, hvordan de manifesterer seg og hva som ligger til grunn for dem, har vært studert i over 100 år. Begrensninger i temperatur har lenge vært ansett som en av de viktigste ... -
Vascular plant and lichen functional trait responses to warming in an alpine ecosystem
Knutsen, Maria Skar (Master thesis, 2018)Functional traits are recognized as potential predictors of plant community responses to climate change. In stressful alpine environments, temperature is a limiting factor and may select for resource conservative individuals. ...
