Impacts of flood-mediated disturbance on species of High Nature Value farmland
… are better described as being dependent on disturbance, and that management practices on HNVf mimics the effects of natural disturbance processes such as herbivory, fire, severe weather and flooding, which are often suppressed across much of Europe. If true, one innovative approach for …

Spatial Drivers of Ecosystem Structure and Function in a Floodplain Riverscape: Springbrook Nutrient Dynamics
On riverine floodplains, reorganization by fluvial processes creates and maintains a mosaic of aquatic and riparian landscape elements across a biophysical gradient of disturbance and succession. I hypothesized that ecosystem processes in spring brooks would differ spatially across biophysical …

Form and function: quantifying geomorphic heterogeneity and drivers in dryland non-perennial river corridors
… of extant studies focus on in-channel dynamics. Floodplains along perennial streams are known to host a high density of ecosystem functions, including the attenuation of downstream fluxes and provision of habitat to diverse flora and fauna. These functions are thought to be correlated to …

Vegetation patterns along the Middle Fork of the Flathead River, Glacier National Park, Montana
Distribution of riparian vegetation on riverine floodplains is dictated, in part, by species' response to flood disturbance. Plant position can be related to frequency, intensity and duration of flooding, with species most tolerant of flooding occurring in lower discharge classes and those less …

Effects of native forest and pastoral land use on the population dynamics and trophic role of the New Zealand freshwater crayfish Paranephrops planifrons (Parastacidae)
… pasture streams were not as resistant to a major flood disturbance as those in native forest streams, suggesting that the habitats in these pasture streams did not provide stable refugia. Furthermore, the rate of recovery of a crayfish population in one pasture stream following the flood was very …

Effects of Landscape Disturbances on Autotrophic Processes Within Arkansas Ozark Streams
… and impacted sites before and after the disturbance occurred for the autotrophic processes measured. These results suggest that BMPs were effective at mitigating effects of low levels of NG activity. However, NG activity in the study watersheds was less than in surrounding areas, …
