Photocells were traversed at 6 canopy heights in a 15-yr-old plantation in North Carolina. When incident radiation was predominantly direct-beam, a bi...

Agricultural and invasive weeds are major threats to managed and natural ecosystems, costing billions of dollars annually. Models for arable and invas...

Anthropogenic activities influence ongoing selective regimes leading to changes in phenotypic variation of plants and animals. The reduction of phenot...

Fragmentation of tropical forest is accelerating at the same time that already cleared land reverts to secondary growth. Fragments inexorably lose dee...

Ecological systems are prone to disturbances and perturbations. For stage-structured populations, communities and ecosystems, measurements of system m...

With accelerating urbanization, the urban contribution to biodiversity conservation becomes increasingly important. Previous research shows that citie...

Quantifying interactive effects of environmental drivers on population dynamics can be critical for a robust analysis of population viability. Fire re...

Wildfires are increasing in both frequency and intensity in many ecosystems, with climate change models predicting further escalations in fire-prone e...

Total solar, near infra-red, and photosynthetically active radiation were measured by tube solarimeters at Rothamsted in barley, sugar beet, field bea...

There is increasing evidence that disease-mediated invasions are widespread across a range of vertebrate, invertebrate and plant systems. We therefore...
