Effects of pretreatment tree dominance and conifer removal treatments on plant succession in sagebrush communities
… resistance of the shrub-grass dominated state. Successional trajectories following disturbance are highly dependent upon residual species abundance, composition, and resulting structure. Understanding how tree dominance and tree-reduction treatments interact over time will help inform …

Primary plant succession at Franz Josef Glacier: Aspects of predictability and ecophysiology: A dissertation submitted in partial fulfilment of the requirement for the Degree of Bachelor of Horticultural Science (Honours) at Lincoln University
… sites were selected from a previous study of plant succession and pedogenesis at Franz Josef Glacier by Stevens (1963; 1968). Plant species diversity and abundance were recorded on the 3 youngest sites, aged 45 to 85 years in the present study. Floristic composition was compared to composition …

Ecological succession on abandoned farmland and its relationship to wildlife production in Cumberland County, Virginia
… by the activities of man. This sequence or plant changes has associated with it an animal population which is probably governed by floristic alterations. There are few quantitative data available on the relationship of these plant successional changes on the associated animal populations. …

Plant-Soil Feedbacks In Heavy Metal Soils
… is critical for human and environmental health. Plant-soil feedbacks (PSFs), in which plants affect other plants indirectly by modifying the soil they grow in, have been shown to affect many processes critical to successful restoration, but we know little about their generality across ecosystems …

Bird perches and soil amendments as revegetation techniques for landslides in Puerto Rico
… The loss of the topsoil layer is detrimental to plant establishment and plant succession as it contains the soil seed bank, as well as the majority of the nutrients essential for plant growth. In this study, I introduced bird perches to six Puerto Rican landslides with three types of surfaces …

Spatial modeling and visualization of habitat response to hydrologic restoration in New England salt marshes
… the distribution of dominant salt marsh plants and invasive species. An ecosystem model was developed to better predict salt marsh habitat response to hydrologic modification as a synthesis of existing models for biomass production, marsh elevation, tidal hydrology, and plant succession. …

THE LIFE HISTORY AND ECOLOGY OF RIVERINE SOCKEYE SALMON (ONCORHYNCHUS NERKA) IN A LARGE FLOODPLAIN RIVER
… transport, cut and fill alluviation, woody plant succession, and ecosystem engineers, notably beavers, that create dynamic and biophysically complex off-channel rearing and spawning habitats. Sockeye salmon (Oncorhynchus nerka) display some of the most variable life history traits of all …

Predicting rates and patterns of alien plant spread
The invasion of alien plants into natural ecosystems is a widespread phenomenon that impacts negatively on ecosystem structure and functioning. The invasion and subsequent spread of an alien plant population is equivalent to the processes of colonisation and migration. This implies that the …

Erosion control with vegetation in highway corridors
… of developing a vegetative cover and shifts in plant biota to persistent covers depend on grading and subsoil preparation, soil amendments, mulches, and specially designed seed mix:tures for seeding at various seasons. The management of these factors, through plant succession, results in …

Impact of clearcutting on indigenous mammals of southwest Virginia
… Mammals generally associated with older plant communities were either absent in the 2-yr cut, or were infrequently captured and rarely observed during the snow track counts. Other species increased in relative numbers over the uncut the more shade tolerant herbs. This sere also evidenced …

Small mammal demographics in North Dakota conservation reserve program plantings
… dynamics in Conservation Reserve Program (CRP) plantings in north central North Dakota. Four age classes (1-4 years) of CRP plantings were sampled. Small mammal species diversity was low (H'=0.057-0.374). Eight species of small mammals were captured on CRP tracts, with deer mice (Peromyscus …

Plant Successional Patterns at Sperry Glacier Foreland, Glacier National Park, MT, USA
… retreat provides a unique opportunity to study succession across the chronosequences of glacier forelands. Patterns of plant colonization and succession on terrain exposed by retreating glaciers give insight into factors influencing alpine ecosystem change and recovery. Understanding these …
