Relationship between coastal vegetation biomass with elevation and salinity gradients
… to property and loss of life in coastal areas. Vegetation in wetlands and coastal fringes can reduce storm surges and waves while complementing traditional coastal defense approaches such as permanent levees, seawalls and gates. The effectiveness of marsh vegetation in attenuating storm surge …

Spatial and Seasonal Patterns of Above- and Belowground Vegetation Biomass and Potential Drivers in the Pascagoula River Delta, MS
… the effects of inundation and nitrogen on vegetation productivity using a field-sampling approach and an <em>in situ</em> controlled mesocosm experiment, called a marsh organ. The West Channel of the Pascagoula River contained significantly higher belowground biomass than the East Channel, …

Estimating above and below ground vegetation biomass and carbon storage across an intra-urban land-use gradient in mid-Missouri
… six intra-urban 50m2 plots were surveyed for vegetation characteristics such as species richness, basal area, proportion invasive species, and species morphometrics. Morphometric data were used to quantify vegetative biomass and carbon storage. Trees within the bottomland hardwood forest were …

Topografian, maaperän ja geomorfologian vaikutukset putkilokasvien biomassan vaihteluun oroarktisella tunturikankaalla
Climate change is predicted to cause changes in vegetation productivity and biomass in northern areas. Understanding the factors affecting biomass helps us to estimate the future changes in plant communities and the amount of carbon stored in vegetation. In this thesis I examine the effects of soil …

The potential of airborne polarimetric synthetic aperture radar data for quantifying and mapping the biomass and structural diversity of woodlands in semi-arid Australia.
… potential in the estimation and mapping of vegetation biomass and subsequently carbon. The aim of this research is to investigate the potential of airborne polarimetric radar for quantifying and mapping the biomass and structural diversity of woodlands in semi-arid Australia. Initial …

Factors Affecting the Distribution and Abundance of Microtus Ochrogaster and M. Pennsylvanicus in East-Central Illinois (Competition, Agonistic)
… Multivariate analysis of variance of the vegetation characteristics of M. ochrogaster and M. pennsylvanicus sites were characterized by a greater total vegetation biomass, a higher percent composition of grasses other than Poa and by a lesser amount of Taraxacum than were M. ochrogaster …

Integrating the effects of climate change and caribou herbivory on vegetation community structure in low Arctic tundra
Arctic tundra vegetation communities are rapidly responding to climate warming with increases in aboveground biomass, particularly in deciduous shrubs. This increased shrub density has the potential to dramatically alter the functioning of tundra ecosystems through its effects on permafrost …

Nesting and Brood-Rearing Success and Resource Selection of Greater Sage-Grouse in Northwestern South Dakota
… and bluegrass (Poa spp.) cover. More herbaceous vegetation at these sites may provide increased invertebrate abundance, which is necessary in the diets of sage-grouse chicks. Management of sage-grouse nesting habitat on the eastern edge of their range should focus on increasing levels of …

The role of territoriality in the mating system of the springbok Antidorcas marsupialis (Zimmerman 1780)
… independent of ecological conditions including vegetation biomass, rainfall and the distance from the nearest waterhole. The social organisation of springbok exposed territorial males to the highest predation risk, whilst males in general risked a higher predation threat than females. This was …

Forest Harvesting Disturbance and Site Preparation Effects on Soil Processes and Vegetation in a Young Pine Plantation
… taeda L.) in response to controlling non-crop vegetation is well documented. However, the beneficial effects of non-crop vegetation on soil quality, nutrient cycling, and biodiversity have not been thoroughly explored. A study was conducted to determine the effects of harvesting-induced soil …

Changes in distribution of indigenous forest in Table Mountain National Park from 1880-2012
… as one of the South Africa's most vulnerable vegetation types. Despite this, forest remains one of South Africa's most under-researched ecosystems and the country has few dedicated forest ecologists. This research examines changes in distribution of Western Cape Afrotemperate Forest and …

Exploring the use of GPS-tracking to investigate the diet of African vultures
… there was an 85% chance of detecting a carcass. Vegetation biomass at the sites, and the vulture species involved, had no influence on the likelihood of detecting a carcass. My study, on the application of GPS-tracking to understand the diet of a sample of African vultures in Botswana suggests …

Effects of Landscape Age and Salinity on Plant Community Composition and Productivity in Opportunistic and Constructed Wetlands in the Athabasca Oil Sands Region, Alberta
… to determine how salinity and age influence the vegetation community composition, and the biomass of six dominant wetland plant species (Carex aquatilis, Calamagrostis canadensis, Carex atherodes, Carex utriculata, Schoenoplectus tabernaemontani, and Typha latifolia) found on reclaimed and …

River - Riparian Vegetation Interactions
… attention will be focused on plants. Riparian vegetation is of great interest because of its double role, passive and active. In the first role (i.e. the passive one) the biological activity is not considered and only the effect of vegetation morphological and mechanical characteristics on …
