Scaling, energetics and diversity
Article Abstract:
Enquist and colleagues have demonstrated a theoretical model drawn from a sample of 2,283 trees of 45 species measured 20 years apart, from dry tropical forest in Costa Rica. They show that a large number of different species show a link between diminishing growth and increasing size. It shows that usable energy is being deployed in a range of growth-form, life-history and wood-density strategies, that lead to differing ways of attaining the same energy use.

Competition and coexistence
Article Abstract:
Huisman and Weissing have shown through numerical modelling, that the competition dynamics of systems with more than two limiting resources, are different from those with just two limiting resources. Sustained oscillations of resource concentrations and of species's abundance are possible, creating the environment variability required for the persistence of more species than the limiting resource appear to allow.
