This laboratory study describes the sediment patterns formed in a sand bed around circular
patches of rigid vertical cylinders, representing a patch of reedy emergent vegetation. The …

This study investigates whether (1) structural configuration (considering substrate
composition, wood debris, marginal and riparian vegetation) of streams suggests habitat …

Introduced submerged macrophytes have come to dominate many shallow water bodies in
New Zealand, and are a common component of many lowland streams. We investigated the …

The effects of macrophytes on hydraulic and physico-chemical variables were examined by
conducting tracer experiments with SF 6, CH 3 Cl and rhodamine WT in a stream before and …

In recent years, river restoration science has been searching for biological indicators of
improvement in the physical habitats of streams. To date, research has mainly focused on …

Invasive macrophytes can have a variety of effects on aquatic ecosystems. The early
detection and abundance estimation of an invasive species is important to effectively control …

The expansion of beavers into human-dominated landscapes can help improve the
ecological status of degraded streams. This study aimed to assess the changes in the …

We sampled epiphytic and benthic macriinvertebrates in 20 beds of submersed vegetation
throughout the Hudson River estuary to assess the importance of plant beds in providing …
