A strategy for reducing complex chemical reaction mechanisms is developed and illustrated
with reference to the oscillatory H 2 + O 2 system in a CSTR in the region of the second …

We investigate the dynamical behaviour of a simple plankton population model, which explicitly
simulates the concentrations of nutrient, phytoplankton and zooplankton in the oceanic …

We examine the qualitative behaviour of an NPZ (nutrient-phyto- plankton-zooplankton)
model for parameter ranges consistent with values used in the literature. The wide range of …

We investigate systematically the effect of small-scale biological and physical processes on
the generation of plankton patchiness, and on the biological production averaged over …

Deficiency in bioavailable iron and grazing pressure have been proposed as alternative
explanations for the existence of oceanic high nutrient-low chlorophyll (HNLC) regions. We …

Reduced chemical mechanisms describing thepyrolysis of pure propane in a cracking tube
with a uniform firebox temperature are presented. The full chemistry is taken from the model …

Models of fish recruitment must include a realistic description of the underlying prey population
dynamics. In the example presented here a model for the growth of haddock larvae (…

A simple mathematical model is presented for the population dynamics of fish larvae when
the main food supply, in this case copepods, is spatially patchy in its distribution. Encounters …

Evolution equations are developed for weakly nonlinear baroclinic wave packets in a flow
with continuous shear and stratification. When wave dispersion is forced by using sloping …

Intratrophic predation is a phenomenon not usually considered in mathematical models of
biological populations, and yet it may occur in any model where many species are considered …
