Studies on populations of Folsomia candida (Insecta: Collembola) : The productivity of populations in relation to food and exploitation.

摘要: Experiments are described that were designed to investigate the effects of food availability and rate exploitation on growth production populations Folsomia candida (Willem). In an initial experiment in which there was excess it found increasing resulted increases both numerical biomass productivity populations. a second shown that, when is severe competition for food, does not affect either or production. It concluded effect overcrowding, form space, contribute numbers populations, but supply plays more important role regulating population. Anomalous results, showing has lesser discussed.
