Estudio preliminar de la
microfauna del suelo en areas de varillales y chamizales de la Amazonia peruana.

However, microbial-feeding nematodes and other
microfauna had managed to contaminate the control systems, developing to high densities (771 x [10.sup.3] + 343 X [10.sup.3] and 750 x [10.sup.3] [+ or -] 485 X [10.sup.3] nematodes/[m.sup.2], mean [+ or -] SD) in the systems with pine and birch seedlings, respectively, by the end of the experiment.
The first core was analysed for mesofauna (modified Bedese-Tullgren funnel), the second for
microfauna (modified tray method), the third for soil chemistry (Olsen P, pH, [sup.15]N; see below) and the fourth soil core was collected in a 50-mm-diameter PVC pipe and assessed for soil structure (see below).
Other reptilian and therian groups were also well represented, in particular those that made up the
microfauna. Several groups that have traditionally been somewhat disregarded were examined in the Symposium, and have been included in this Special Issue.

Consequently, it can be concluded that low abundance and species number values observed in the
microfauna do not seem to be due to the persistent pollution in the estuary.
En la actualidad, para facilitar el estudio del zoobentos en general, se acepta a nivel internacional las categorias propuestas segun el diametro esferico de sus individuos que les permite explotar como grupos diferentes los recursos y nichos disponibles en ambientes bentonicos, estas categorias son:
Microfauna (<45 [micron]m), Meiofauna (45-500 [micron]m), Macrofauna (>500 [micron]m-4.0 mm) y Megafauna (>4.0 mm) (Duplisea y Hargrave 1996).
