The bioassessment of aquatic ecosystems is currently based on various biotic indices that
use the occurrence and/or abundance of selected taxonomic groups to define ecological …

Abstract Small, 1st and 2nd-order, headwater streams and ponds play essential roles in
providing natural flood control, trap** sediments and contaminants, retaining nutrients …

Excessive sediment pressure on aquatic habitats is of global concern. A unique dataset,
comprising instantaneous measurements of deposited fine sediment in 230 agricultural …

Excess fine sediment, comprising particles< 2 mm in diameter, is a major cause of
ecological degradation in rivers. The erosion of fine sediment from terrestrial or aquatic …

Monitoring programmes worldwide use biota to assess the “health” of water bodies. Indices
based on biota are used to describe the change in status of sites over time, to identify …

Headwater streams are natural sources of methane but are suffering severe anthropogenic
disturbance, particularly land use change and climate warming. The widespread …

Excessive fine sediment (particles< 2 mm) deposition in freshwater systems is a pervasive
stressor worldwide. However, understanding of ecological response to excess fine sediment …

Anthropogenic modifications of sediment load can cause ecological degradation in stream
and river ecosystems. However, in practice, identifying when and where sediment is the …

Increased fine sediment deposition is recognised as one of the major causes of biological
impairment of rivers and streams influencing all components of aquatic communities …

Unrestricted cattle access to rivers and streams represent a potentially significant localised
pressure on freshwater systems. However there is no consensus in the literature on the …
