The assessment of the environmental hazards posed by chemical pollutants typically results from single-species tests that are extrapolated to ecosyste...

We still lack practical guidelines for diversifying cropping systems that consider both yield and regulating functions of agroecosystems. Recent studi...

Cut-away peatlands devoid of vegetation form a persistent source of carbon (C) to the atmosphere. The restoration of the C sink function in such areas...

Net CO₂ uptake over 24-h periods was determined in the field under various conditions. In Saltillo, Coahuila, Mexico, which is near the centre of dist...

The loss of foundational but fire-intolerant perennials such as sagebrush due to increases in fire size and frequency in semi-arid regions has motivat...

Using sugar-beet seedlings as phytometers, NAR, LAI and light intensity were measured at various levels in field-grown spring barley, winter wheat, sp...

Riparian trees regulate aquatic ecosystem processes, such as inputs of light, organic matter and nutrients, that can be altered dramatically when thes...

The magnitude and spatial scales of human effects on stream habitats need to be correctly measured to achieve sound ecosystem management. We investiga...

Conventionally, agent host specificity has been the major concern in the selection of prospective agents for biological control of weeds. However, sub...

Degradation from overgrazing of global arid rangelands is of significant concern for this widespread terrestrial ecosystem, and the people who rely on...
