the study was carried out in the ilam oak forest that is located in the west part of iran. the objective of this research was to determine the plant ecological groups and site classification in this region. data were collected from 117 sample plots using the systematic-random sampling method. the size of sampling plots was 20 m?20 m for the tree and shrub species and 1.5 m ?1.5 m for herbaceous...

Agglomerative clustering, Two Way Indicator Species Analysis (WINSPAN), and Detrended Correspondence Analysis (DCA) were used for the plant community analysis. Remotely sensed data was used as a surrogate in identifying and locating field sites from where floristic composition, environmental and spatial data were collected. Characteristic plant species of each community type are presented toget...

Species richness and productivity are two fundamental aspects of ecosystems. As a result, the relationship between species richness and productivity has been widely studied. A series of fertilisation experiments in an alpine meadow on the Tibetan Plateau were performed to study the relationship between species richness and productivity. In this paper, we present a novel indicator, i.e., space r...

While bryophytes greatly contribute to plant diversity of semi-natural grasslands, little is known about the relationships between land-use intensity, productivity, and bryophyte diversity in these habitats. We recorded vascular plant and bryophyte vegetation in 85 agricultural used grasslands in two regions in northern and central Germany and gathered information on land-use intensity. To asse...

Forests are being clearcut over extensive areas of western North America, but plant community response to harvesting and slashburning under varying climatic conditions in central British Columbia, Canada is still largely unknown. Evaluation of resilience is hampered by the short history of logging, lack of long-term experiments and methodological limitations. To test the effect of clearcut logg...
