Long-Term Climate Regime Modulates the Impact of Short-Term Climate Variability on Decomposition in Alpine Grassland Soils
(Peer reviewed; Journal article, 2018-12)Decomposition of plant litter is an important process in the terrestrial carbon cycle and makes up approximately 70% of the global carbon flux from soils to the atmosphere. Climate change is expected to have significant ... -
Long-term disturbance dynamics and resilience of tropical peat swamp forests
(Peer reviewed; Journal article, 2015-01)1. The coastal peat swamp forests of Sarawak, Malaysian Borneo, are undergoing rapid conversion, predominantly into oil palm plantations. This wetland ecosystem is assumed to have experienced insignificant disturbance in ... -
A low climate threshold for south Greenland Ice Sheet demise during the Late Pleistocene
(Peer reviewed; Journal article, 2020-01-07)The Greenland Ice Sheet (GIS) has been losing mass at an accelerating rate over the recent decades. Models suggest a possible temperature threshold between 0.8 and 3.2 °C, beyond which GIS decline becomes irreversible. The ... -
Norwegian margin outer shelf cracking: a consequence of climate-induced gas hydrate dissociation?
(Peer reviewed; Journal article, 2010)A series of en echelon cracks run nearly parallel to the outer shelf edge of the mid-Norwegian margin. The features can be followed in a *60-km-long and *5-km-wide zone in which up to 10-m-deep cracks developed in the ... -
Plant-pollinator interactions in the alpine: Landscape heterogeneity acts as a potential buffer against climate-change induced mismatch in the pollinator-generalist Ranunculus acris
(Master thesis, 2018-06-19)Phenology changes are a common response to global warming and the timing of phenological events is important for symbiotic interactions, such as pollination. If symbiotic species respond differently to global warming, this ... -
Plastic Population Effects and Conservative Leaf Traits in a Reciprocal Transplant Experiment Simulating Climate Warming in the Himalayas
(Peer reviewed; Journal article, 2018-07-30)Climate warming poses considerable challenges for alpine plant species, especially for competitively inferior ones with resource-conservative adaptations to cold climates. The Himalayas are warming at rates considerably ... -
The potential of sedimentary ancient DNA for reconstructingpast sea ice evolution
(Peer reviewed; Journal article, 2019-06-24)Sea ice is a crucial component of the Arctic climate system, yet the tools to document the evolution of sea ice conditions onhistorical and geological time scales are few and have limitations. Such records are essential ... -
Recent environmental change and atmospheric contamination on Svalbard as recorded in lake sediments – synthesis and general conclusions
(Peer reviewed; Journal article, 2004)The major patterns of biostratigraphical and geochemical change detected in a multidisciplinary study on recent environmental change and atmospheric contamination on Svalbard are summarised and synthesized. The patterns ... -
Resilience to exogenous shocks in environmental management regimes in the Arctic – lessons learned from survivors
(Peer reviewed; Journal article, 2019-06-13)A changing climate will impact not only the environment but all levels of governance thereof, including the context of the close to 400 multilateral environmental management agreements signed since the year 2000. For the ... -
The Role of Atlantic Heat Transport in Future Arctic Winter Sea Ice Loss
(Peer reviewed; Journal article, 2019-05-14)During recent decades Arctic sea ice variability and retreat during winter have largely been a result of variable ocean heat transport (OHT). Here we use the Community Earth System Model (CESM) large ensemble simulation ... -
Site- and horizon-specific patterns of microbial community structure and enzyme activities in permafrost-affected soils of Greenland
(Peer reviewed; Journal article, 2014-10-16)Permafrost-affected soils in the Northern latitudes store huge amounts of organic carbon (OC) that is prone to microbial degradation and subsequent release of greenhouse gasses to the atmosphere. In Greenland, the consequences ... -
Species composition, distribution and ecology of the demersal fish community along the Norwegian coast north of Stad under varying environmental conditions
(Master thesis, 2019-06-14)In the last decades, temperatures of the Atlantic current that enters the Norwegian Coastal Current (NCC) has been above the yearly average, with 2007 as the warmest registration on record (Skagseth 2012). The climatic ... -
Treeline and vegetation dynamics in response to environmental changes in Nepal, the central Himalaya
(Doctoral thesis, 2013-05-31)Aims: To describe and evaluate patterns of vegetation response to ongoing environmental changes across climate-limited (alpine treeline ecotone) and humanmodified (temperate Himalayan oak forests) ecosystems in Nepal, ...
