An agent-based approach to food web assembly
Craig R. Powell
An agent-based model of population dynamics is presented. The model has as its expected behaviour the population dynamics of the equation-based Webworld model, within which large c…
The effects of stochastic population dynamics on food web structure
Craig R. Powell, Richard P. Boland
We develop a stochastic, individual-based model for food web simulation which in the large-population limit reduces to the well-studied Webworld model, which has been used to succe…
Effects of food web construction by evolution or immigration
Craig R. Powell, Alan J. McKane
We present results contrasting food webs constructed using the same model where the source of species was either evolution or immigration from a previously evolved species pool. Th…
Predicting the species abundance distribution using a model food web
Craig R. Powell, Alan J. McKane
A large number of models of the species abundance distribution (SAD) have been proposed, many of which are generically similar to the log-normal distribution, from which they are o…
Mass transfer during low mass X-ray transient decays
Craig R. Powell, Carole A. Haswell, Maurizio Falanga
The outbursts of low mass X-ray binaries are prolonged relative to those of dwarf nova cataclysmic variables as a consequence of X-ray irradiation of the disc. We show that the tim…
Optical spectroscopy of flares from the black hole X-ray transient A0620-00 in quiescence
T. Shahbaz, R. I. Hynes, P. A. Charles +5
We present a time-resolved spectrophotometric study of the optical variability in the quiescent soft X-ray transient A0620-00. Superimposed on the double-humped continuum lightcurv…
