Plant species composition of boreal spruce swamp forests: closed doors and windows of opportunity
Økland, Rune Halvorsen; Rydgren, Knut; Økland, Tonje (Journal article; Peer reviewed, 2003)Previous studies point at biogeographic (i.e. evolutionary and demographic) and ecological (i.e. habitat differentiation and disturbance) processes as the most important causes of spatial variation in species richness and ... -
Recreating semi-natural grasslands: a comparison of four methods
Rydgren, Knut; Nordbakken, Jørn-Frode; Austad, Ingvild; Auestad, Inger; Heegaard, Einar (Journal article; Peer reviewed, 2010) -
Red deer mediate spatial and temporal plant heterogeneity in boreal forests
Lilleeng, Marte Synnøve; Hegland, Stein Joar; Rydgren, Knut; Moe, Stein Ragnar (Journal article; Peer reviewed, 2016)Selective herbivory can influence both spatial and temporal vegetation heterogeneity. For example, many northern European populations of free-ranging ungulates have reached unprecedented levels, which can influence plant ... -
Scale-dependence of vegetation-environment relationships in semi-natural grasslands
Auestad, Inger; Rydgren, Knut; Økland, Rune H. (Peer reviewed; Journal article, 2008) -
Species richness in boreal swamp forests of SE Norway: the role of surface microtopography
Økland, Rune H.; Rydgren, Knut; Økland, Tonje (Peer reviewed; Journal article, 2008)Question: What is the relative importance of environmental gradients and surface microtopography (variation in vertical level within sampling units) for fine-scale plant species richness in Picea abies swamp forests? Location: ... -
The devil is in the detail: non-additive and context-dependent plant population responses to increasing temperature and precipitation. Plant demography in a warmer & wetter climate
Töpper, Joachim Paul; Meineri, E.; Olsen, Siri Lie; Rydgren, Knut; Skarpaas, Olav; Vandvik, Vigdis (Journal article; Peer reviewed, 2018)In climate change ecology, simplistic research approaches may yield unrealistically simplistic answers to often more complicated problems. In particular, the complexity of vegetation responses to global climate change begs ... -
Ultimate costs of sporophyte production in the clonal moss Hylocomium splendens
Rydgren, Knut; Økland, Rune H. (Journal article; Peer reviewed, 2002)A richly sporophyte-producing population of the dioecious perennial clonal moss Hylocomium splendens was followed for five years in order to investigate the longterm costs of sporophyte production. Female mature segments ... -
Use climatic space-for-time substitutions with care: Not only climate, but also local environment affect performance of the key forest species bilberry along elevation gradient
Auestad, Inger; Rydgren, Knut; Halvorsen, Rune; Avdem, Ingrid Hofmo; Berge, Rannveig; Bollingberg, Ina Marie; Lima, Oline (Peer reviewed; Journal article, 2023)An urgent aim of ecology is to understand how key species relate to climatic and environmental variation, to better predict their prospects under future climate change. The abundant dwarf shrub bilberry (Vaccinium myrtillus ...
