A damming history: an analysis on the legacy effects of beaver dams on the composition and structure of a montane riparian ecosystem
… widely recognized for its positive influence on ecosystem diversity and stability. As an "ecosystem engineer," the American beaver (Castor canadensis) increases heterogeneity in riparian systems through dam-building activities, resulting in diverse wetland complexes. This study explored the …

Differentiated use and value of river and riparian ecosystem services and local perspectives on future safeguarding: A case study of the upper Mutale sub-catchment, Limpopo River Basin, South Africa
… five decades, human-driven changes in natural ecosystems have resulted in biodiversity loss and a decline in ecosystem services, particularly affecting freshwater ecosystems. The response to these challenges has led to the adoption of nature-based solutions, emphasizing the restoration and …

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 …

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 …

A Comparison of Wildlife Monitoring Techniques in Riparian Ecosystems of the Western United States
<p>Many riparian restoration projects in the western United States have not implemented monitoring plans. This lack of wildlife monitoring has resulted in a loss riparian ecosystem services and missed opportunities to conserve them. Data collected from wildlife monitoring assists researchers, …

Riparian willow decline in Colorado: interactions of ungulate browsing, native birds and fungi
… spp.) are critical components of Rocky Mountain riparian ecosystems. They provide food for ungulates and beavers; habitat for resident and migratory bird populations, and amphibians; and are integral components of the structure and function of montane riparian ecosystems. In Rocky Mountain …

Beaver moderated fire resistance in the North Cascades and potential for climate change adaptation
… for harmful channel incision, which impairs riparian ecosystem function by lowering the water table, disconnecting floodplains from aquatic environments. However, wetlands and functioning riparian zones can reduce burn intensity. Beaver, with their unique ability to build dams, can restore …

The effects of replanting and restoration of riparian buffers on arthropods in oil palm systems
… declines in biodiversity and changes in ecosystem processes. Protecting natural habitats is a conservation priority. However, once oil palm plantations are established, it is important to investigate how changes in management can affect oil palm systems, which can be relatively …

Management and Mother Nature: piping plover demography and condition in response to flooding on the Missouri River
Globally, riparian ecosystems are in decline due to anthropogenic modifications including damming, channelization and the conversion of the floodplain for human use. These changes can profoundly affect riparian species as many have adapted to the historical dynamism of these ecosystems. On the …

Riparian understory dynamics and relationship to dams on the Elwha River, Washington
… sediment regimes, which can fundamentally alter riparian ecosystem function. However, with better understanding of how dams negatively impact river systems, and as many dams approach the end of their lifespan, dam removal is being used to facilitate ecosystem restoration. Whereas researchers have …

Nitrogen transport and dynamics in grass filter strips
Field research was conducted to investigate the impact of vegetative filter strips (VFSs) on surface runoff water quality and to determine if this impact decreases with time. The field research provided information for the development and testing of a model to describe the dynamics and fate of …

Population Dynamics of Willow Flycatchers in the Sierra Nevada
… may be further suppressed alterations to the riparian habitat that they rely on for breeding. I found a trend towards decreased nest survival with distance from forest edges in large meadows where the majority of breeding flycatchers are in the central regions. Alternatively, edge effects …

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 …

CARBON AND NITROGEN CYCLING IN GIANT CANE (ARUNDINARIA GIGANTEA (WALT.) MUHL.) RIPARIAN ECOSYSTEMS
… canebrakes, were vital to wildlife and lowland ecosystem functions and historically covered millions of acres in the southeastern United States. Since European settlement, human disturbance (i.e, clearing for agriculture and fire suppression) has caused giant canebrakes to become critically …
