Flood Hydraulics and Impacts on Invasive Vegetation in a Braided River Floodplain, New Zealand

Landscape configuration and flood frequency influence invasive shrubs in floodplain forests of the Wisconsin River (USA)

1. Invasive species are present worldwide, yet predicting which invasive species will become problematic in which ecosystems remains an important ecological challenge. Floodplains are at particular risk for invasion, especially when subjected to anthropogenic disturbance. 2. We examined how components of flood regime, habitat quality and habitat configuration influenced the presence and abundan...

Vegetation on the edge: a gradient analysis of the riparian zone, Poerua River, New Zealand

Forest vegetation patterns alongside the Poerua River, south Westland, were studied to determine whether a distinct riparian community could be defined either immediately adjacent to the river, or out to the limit of overbank flooding. Ten randomly located 100 m transects were established perpendicular to the river at each of two sites. Ground cover of alluvial sediment indicated that annual ov...

Applicability of the Flood-pulse Concept in a Temperate Floodplain River Ecosystem: Thermal and Temporal Components

Annual growth increments were calculated for blue catfish (Ictalurus furcatus) and flathead catfish (Pylodictis olivaris) from the lower Mississippi River (LMR) to assess hypothesized relationships between fish growth and floodplain inundation as predicted by the Flood-Pulse Concept. Variation in catfish growth increment was high for all age classes of both species, and growth increments were n...

effect of riparian vegetation on morphometric and morphological indexes in braided part of talar river

in present study effects of riparian vegetation on morphometric and morphological changes have been investigated in a part of talar river during 58 years. so land use maps produced for 1955 and 2013 by aerial photos. results show during study time riparian vegetation changed extremely and approximately 96% of riparian vegetation removed during 58 years. in additionally, results showed during st...
