The generation of plankton patchiness by turbulent stirring
Article Abstract:
The formation of spatial patterns in biological systems are often represented by diffusive processes. Patchiness in planktonic ecosystems may be generated via non-diffusive advection. Plankton surface distributions are distinguished by spectra concentrations, which often have a power-law form over horizontal ranges between one to 100 km. Zooplankton density can be as variable at short scales as long ones, with phytoplankton distributions being similar to those of physical quantities, and of lower variability at shorter length scales.

A question of litter quality
Article Abstract:
A meeting of plant physiologists, ecologists and soil scientists examined the hypothesis that the changed chemistry of dead leaves, grown in an environment high in CO2, will mean that there will be a decline in the decomposition rate. It was concluded that there was insufficient evidence to support such a hypothesis. However other potential feedbacks on nitrogen availability are still important and there is still a need to distinguish the processes controlling decomposition in Co2-enriched ecosystems.

The natural economy
Article Abstract:
Issues concerning the study of ecosystems are discussed. In particular the rudimentary nature of much knowledge about the impact of humanity on global life support systems is examined.
