As humans increasingly alter the surface geomorphology of the Earth, a multitude of artificial
aquatic systems have appeared, both deliberately and accidentally. Human modifications to …

We evaluated relationships between in-stream habitat, spatial distribution, and geomorphic
features at 28 study sites within a predominantly agricultural watershed in Ohio. Objectives …

Artificial drainage of forested wetlands to increase timber production has profoundly altered
the hydrology of North-European landscapes during the 20th century. Nowadays, drainage …

A better understanding of how human activities affect biodiversity can be important for
effective resource management. We tested how excavation (maintenance) of agricultural …

Water quality and stream habitat in agricultural watersheds are under greater scrutiny as
hydrologic pathways are altered to increase crop production. Ditches have been traditionally …

Climate change is now universally acknowledged to be taking place across the globe. It is

Stream fish assemblage structure and function were examined for significant response
along a polychlorinated biphenyl (PCB) gradient from two PCB-contaminated streams (Clear …

We provide a critical review of the massive land drainage works, water resource degradation
and a persistent eutrophication problem in agriculturally-dominated watersheds, such as the …

Headwater streams comprise about half of the total stream length in the US They help
control floods, transport suspended and dissolved matter, and connect upstream landscapes …

Headwaters and their tributaries serve important ecosystem functions including water quality
and biodiversity hotspots. They are often the indicators of ecological health of rivers …
