River - Riparian Vegetation Interactions
The river and the riparian ecosystem are two dynamical systems which exhibit complex spatio-temporal interactions. Because of the possible implications for engineering works and environmental management, in recent times a number of studies has focused on this topic, considering both large- and …

Channel Morphology and Riparian Vegetation Influences on Fluvial Aquatic Habitat
… of spatial scales from watershed landuse to riparian vegetation management to local channel morphology can have hierarchical relationships to local (meso- and macro-) in-stream habitat characteristics. This research examined these influences first by examining the influence of complex channel …

CHARACTERIZATION OF URBAN STORM RUNOFF BY MONITORING SEDIMENTS AND RIPARIAN VEGETATION
Difficulties associated with monitoring urban stormwater quality present considerable challenges to stormwater managers in the arid southwest. Complexities arise from the infrequent occurrence of storm events, their highly localized extent, and the short duration of storm hydrographs. The presence …

Initial response of riparian vegetation to dam removal on the Elwha River, Washington
<p>"Riparian zones, the interfaces between terrestrial and aquatic ecosystems, provide numerous ecosystem functions such as wildlife habitat, erosion control, nutrient and energy storage, buffering of sediment and pollution, and maintenance of biodiversity. Worldwide, riparian ecosystems are …

Effect of Ingestion by Alligator Snapping Turtles (Macrochelys Temminckii) on Seeds of Riparian Vegetation
… fish but also consumes large amounts of vegetation including seeds of common persimmon (Diospyros virginiana), tupelos (Nyssa sp.), willow oak (Quercus phellos), and pecan (Carya illinoensis). Captive specimens of M. temminckii were fed samples of the above-mentioned seeds to assess how …

An investigation of riparian vegetation recovery following invasive alien tree clearing in the Western Cape
Riparian zones are dynamic, as a result of varying levels of disturbance from natural flooding regimes, and this makes them particularly susceptible habitats to invasion by alien plants. In South Africa, particularly the Fynbos Biome, closed-stand invasions by alien Acacia and Eucalyptus species …

Factors affecting the recruitment of riparian vegetation on the Ord and Blackwood Rivers in Western Australia
… involved in the recruitment and regeneration of riparian vegetation. As there has been a paucity of basic ecological studies on riparian vegetation in Australia, the project is broad in scope, and gives a general picture of the factors influencing, the regeneration of riparian vegetation and …

Riparian vegetation and the soil seed bank five years after dam removal on the Elwha River, Washington
… rivers is widespread and can profoundly impact riparian areas by altering the fluvial processes that drive riparian vegetation communities. Dam removal may reverse these effects; however, very few studies have examined the response of riparian vegetation to large dam removal and associated …

Implications for Restoration: Effects of Riparian Vegetation and Shade on Temperature Gradients in Lower Gold Creek, Southwest Montana
… examines the relationship between the amount of riparian shade and mean, minimum, and maximum daily stream temperatures. In addition, this study examines the patterns of riparian vegetation conditions and how they relate to land-use practices within the drainage. These findings in turn indicate …

Influence of riparian vegetation on near-bank flow structure and rates of erosion on a large meandering river
… of the channel banks and floodplains, as well as riparian and in-channel vegetation, modifying rates of erosion and mechanism of bank retreat, often leading to complex planform geometries. While extensive research has been conducted on each of these processes independently, few studies have …

Spontaneous succession of riparian vegetation and aquatic macroinvertebrates along the Silvermine River, South Africa, after fire and clearing of exotic plant species
… changes in the community composition of riparian vegetation, and changes to aquatic macroinvertebrate assemblages present in the river. Data were collected during two successive summer-sampling periods (200 I and 2002) at three study sites along the river. Site I was situated in the …

Land use influences on benthic invertebrate assemblages in southern Appalachian agricultural streams
… at all sites in October 1996 and April 1997. Riparian vegetation was assessed for each site at mutiple spatial scales using GIS data from the 1950s, 1970s, and 1990s. Forested agricultural (FA) streams had more riparian vegetation than cleared agricultural (CA) streams in both the 1950s and …

The Effects of Vegetation on Stream Bank Erosion
Riparian buffers are promoted for water quality improvement, habitat restoration, and stream bank stabilization. While considerable research has been conducted on the effects of riparian buffers on water quality and aquatic habitat, little is known about the influence of riparian vegetation on …

Braided rivers: an exploratory study combining flume experiments and the analysis of remotely-sensed data
… conditions of slope, width, discharge, and riparian vegetation. For the second research element, a Lidar survey of a 36 km reach of the lower Tagliamento river, Italy, was investigated. Within this reach, the river shows only small variations in slope and bed material size and is subject to …

Coupling Agent-Based Models with Bayesian Belief Networks in Social-Ecological Systems Modeling: The Role of Uncertainty in the Resilience of Semi-Arid Riparian Corridors in the Sonoran Desert

HABITAT USE AND THE EFFECTS OF DISTURBANCE ON WINTERING BIRDS USING RIPARIAN HABITATS IN SONORA, MEXICO
Riparian systems are important for breeding bird communities and are highly used as migratory corridors; however, their importance for wintering birds has not been assessed systematically. In order to assess the value of riparian areas for birds wintering in Sonora, data from 1,816 standard point …

A efemeropterofauna do trecho ritral inferior do rio Campo Belo, Itatiaia, RJ: composição e distribuição, com aspectos biológicos e ecológicos das espécies de Americabaetis Kluge, 1992 (Insecta: Ephemeroptera: Baetidae)
… 3.170 specimens were obtained, 1.002 from the riparian vegetation and 786 from litter from pools. The months with the highest number of individuals were November (595 nymphys) and October 1999 (480 nymphys). The two species of Americabaetis present, A. alphus and A. longetron were studied with …
