Effects of reforestation and intensified land use on vascular plant species richness in traditionally managed hay meadows
(Finnish Botanical Publishing Board, 2003)
In this study of 130 sites with different management we investigated whether vascular plant species richness is significantly reduced when traditionally managed hay meadows are abandoned and reforested. We also compared ...
Radiometrically determined dates and sedimentation rates for recent sediments in nine North African wetland lakes (the CASSARINA Project)
Sediment cores were collected from nine wetland lakes in Morocco, Tunisia and Egypt for the CASSARINA project investigating environmental change in Northern African wetlands. The cores were dated radiometrically by using ...
Establishment of Pinus wallichiana on a Himalayan glacier foreland: stochastic distribution or safe sites?
(The Institute of Arctic and Alpine Research, 2006)
The establishment of tree seedlings in primary succession is thought to occur only after an adequate reserve of nutrients has accumulated in the soil. Individuals of Pinaceae are sometimes reported to grow on very recently ...
Fragile mountain - fragile people? Understanding the fragility in the Himalayas : Report on a Workshop in Norway
(International Mountain Society, 2004)
Responses of tundra plants to experimental warming : meta-analysis of the international tundra experiment
(Ecological Society of America, 1999)
The International Tundra Experiment (ITEX) is a collaborative, multisite experiment using a common temperature manipulation to examine variability in species response across climatic and geographic gradients of tundra ...
Palaeolimnological and sedimentary responses to Holocene forest retreat in the Scandes Mountains, west-central Sweden
A suite of analyses was performed on sediments accumulated during the last 10 700 years in Lake Spaime, a small, hydrologically open water body in the modem alpine tundra zone of the Scandes Mountains, west-central Sweden. ...
Holocene climatic change reconstructed from diatoms, chironomids, pollen and near-infrared spectroscopy at an alpine lake (Sjuodjijaure) in northern Sweden
The results of a multiproxy study reconstructing the climate history of the last 9300 years in northern Sweden are presented. It is based on diatom, chironomid and pollen analyses, as well as near-infrared spec troscopy ...
Open water zooplankton communities in North African wetland lakes: the CASSARINA Project
Zooplankton (Copepoda, Cladocera, Ostracoda, Rotifera and Diptera larvae) in nine North African lakes was collected from open water areas over twenty months during 1997/99. The results were used to monitor changes in the ...
What is the observed relationship between species richness and productivity? Comment
(Ecological Society of America, 2003)
Breeding system, insect flower visitation, and floral traits of two alpine cerastium species in Norway
(The Institute of Arctic and Alpine Research, 1999)
The pollination and reproductive ecology of Saxifraga stellaris was investigated in alpine southwest Norway. A breeding system analysis, with performance of controlled crosses, revealed that S. stellaris is self-compatible ...
