Moose effects on soil temperatures, tree canopies, and understory vegetation: a path analysis
Kolstad, Anders Lorentzen; Austrheim, Gunnar; Graae, Bente Jessen; Solberg, Erling Johan; Strimbeck, Richard; Speed, James David Mervyn (Journal article; Peer reviewed, 2018)Large vertebrate herbivores are ubiquitous and increasingly numerous in boreal forests where they are known to influence ecosystems in many ways. However, separating the direct effects of herbivores from their indirect ... -
Net primary production of alpine lichen in a changing environment
Alnes, Vibeke (Master thesis, 2024)Som en konsekvens av de stigende globale temperaturene vil vi se en forandring i hvordan artene fordeler seg i det alpine landskapet. Lavbestandene dominerer fjellområdene sentralt i Norge, og har blitt en kjær del av den ... -
Photosynthetic activity in relation to water content in fruticose lichen species from Norway
Kulawiak, Zuzanna (Master thesis, 2024)Gjennom årene har det blitt gjort betydelig forskning på å forstå fotosyntetisk aktivitet hos skorpe- og bladliknende lavarter, mens buskeformede har fått mindre oppmerksomhet. Buskformede laver, som hvitkrull (Cladonia ... -
Photosynthetic Response to increasing Temperatures - a Comparison between prostrate and erect alpine Shrubs
Eckert, Diana (Master thesis, 2015)As a response to climate change, shrub biomass has increased in alpine and arctic tundra ecosystems. Substantial shrub encroachment can lead to changes in carbon fluxes, due to a shift in community compositions and functional ... -
Photosynthetic Responses of maize (Zea mays L.) seedlings to heat and drought stress
Torgbor, Michael Nii Adjah (Master thesis, 2017)Like all other plants, maize (Zea mays L.) depends on the environment for growth. It is also an important food source for the continuously increasing human population. However, due to the recent changes in climate, maize ... -
Short-term heat stress in situ reduces net photosynthesis and alters metabolite composition in the arctic poppy Papaver dahlianum
Hjermstad-Sollerud, Håvard (Master thesis, 2016)Climate change is increasing the mean summer temperature in the Arctic and with that the probability of extreme climatic events including heat waves. An increase in heat waves may cause increased stress in a number of ... -
Stress responses induced by temperature and light conditions in Brassica napus
Negard, Ane (Master thesis, 2015)Brassica napus, also known as oilseed rape or canola, belongs to the family Brassicaceae. An important characteristic of Brassicaceae is the production of specific secondary metabolites, glucosinolates. Intact glucosinolates ... -
Too Much of a Good Thing: Photoprotection in Boreal Conifers During Winter
Fløystad, Rannveig Bø (Master thesis, 2013)Photochemical utilization of light energy is inhibited in boreal conifers during winter and spring because the carbon fixation reactions slow down due to low temperature. Incoming light can be very strong due to reflection ...
