Effective Mitigation of Sedimentation on Riparian Riverbeds and Salmonid Populations After Dam Removal
<p>Riparian ecosystems rely on longitudinal connectivity of their streams and tributaries to maintain a healthy ecosystem. Longitudinal connectivity is especially important for salmonid populations, which and rely on longitudinal connectivity to reach spawning habitat. Dams prevent longitudinal …

Investigating the habitat selection and dietary preferences of a largely sedentary population of blue wildebeest in the Kgalagadi Transfrontier Park – impacts of permanent surface water provision in a semi-arid environment
… distribution of this resident herd within the riverbeds of the Park. I explore the effects of water quality, forage abundance, tree density and river width on wildebeest habitat selection. I do this through a combination of an analysis of two years of wildebeest census data, published water …

The role of territoriality in the mating system of the springbok Antidorcas marsupialis (Zimmerman 1780)
… in the dry season, and their density on the dry riverbeds remained 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 …

Determining Hydraulic Characteristics in Close Proximity of Hymenocallis coronaria within the Flint River Basin, Georgia
… Carolina. In these states, the geomorphology of riverbeds provides a shallow and swift-moving environment. Anthropogenic alterations along river waterways (e.g., dams) have fundamentally altered the seasonal variation in water flow and sediment transport processes, resulting in declines in …

Hydrological factors influencing the ecology of riverbed breeding birds on the plains' reaches of Canterbury's braided rivers : a thesis submitted in fulfilment of the requirements for the degree of Doctor of Philosophy in the University of Canterbury
The wide, unstable, braided riverbeds of the eastern South Island, New Zealand, have been inhabited by a diverse avifauna. Several species including the wrybill breed only on these rivers. Use is restricted mainly to the breeding season from September to December, so this was the critical study …
