Resilience and recovery of plant communities facing increasing fire severity
… severity, threaten the survival and recovery of plants through lack of adaptation to these extreme occurrences. Beyond impacts on individuals this can shift the composition, structure and functioning of communities. To fully understand the extent of these changes, community-wide studies need to …

Higher fungi in soils of coastal Arctic tundra plant communities
… cm depth was also the zone of maximum vascular plant root concentration. Low levels of resident mycelium were detected at 24 cm depths in all habitats that could be sampled to that depth. Mycelium abundance decreased significantly in highly mineralized soils, but increased at greater depths …

Diversity Relationships in Native, Warm-Season Plant Communities used for Agriculture
Studies suggest that diverse mixtures of plants may improve forage productivity and also be suitable as bioenergy crops. The objectives of this research were: 1) to measure the effects of native, warm-season perennial (NWSP) forage mixtures and management methods on productivity, weed biomass, …

Interplay between competition and evolution in invaded and native plant communities
… can also produce rapid evolutionary change in plant communities. Although our understanding of ecological and evolutionary interactions is growing, so far little is known about how competition among plants interacts with evolution to shape communities. In my dissertation, I use species …

Biogeographical And Evolutionary Processes Influencing The Assembly Of Deciduous Forest Plant Communities
… of individual species and the diversity of communities. In this investigation, I first examined the geographic distribution of an ant-dispersed forest plant, Jeffersonia diphylla, to assess whether the population structure of its geographic range in eastern North America exhibited patterns …

Structure of relict arctic plant communities along the north shore of Lake Superior
… of Lake Superior is home to disjunct arctic plant populations which are relicts from the Wisconsinan glaciation and survive in a cold lake-supported microclimate. Although these species are threatened by climate change, there have been few studies about their structure and diversity and …

Aquatic Plant Communities and Invertebrates in a Prairie Pothole During Duck Brood Rearing
More than 1,100 samples of aquatic plants and associated invertebrates were collected in a prairie wetland. Sampling was done weekly throughout the duck brood rearing season. Linear regression revealed a 4 to 100 ratio of animal to plant biomass (R²=0.488). Comparatively high degrees of association …

Conversion of Exotic Cool-Season Grasslands to Restored Native Plant Communities Utilizing Herbicide Treatments

The restoration of riparian plant communities following alien plant clearing in the Western Cape
… that are highly susceptible to invasion by alien plants. the vegetation of riparian zones controls the flow of water, nutrients and sediments into streams. Plan communities in these habitats are often rish in species, and serve as corridor facilitating the movement of organisms.

Taxonomic homogenization of plant communities in Illinois wetlands and the role of wetland compensation

THE SPATIAL CHARACTERISATION OF TRANSITIONAL AREAS BETWEEN PLANT COMMUNITIES: A CASE STUDY FROM UPLAND BRITAIN
… by Clements (1 905) as a boundary zone between plant communities. Little research exists on the ecological importance or the geographical variability of these zones. Two types of boundaries are acknowledged: the ecotone and the ecocline. The ecotone is a sharp boundary; the ecocline a gradual …
