摘要: Publisher Summary This chapter summarizes the current methods used for sampling soil arthropod populations. Such are in three main types of work: exploratory work that is not concerned with quantitative population estimates, but aimed at finding what species occur an area, “community” studies relative abundance a wide range and often over habitats, “trophic” demand knowledge absolute usually relatively few single habitat. The planning complete system requires careful choice matching experimental design, extraction technique examination counting light above considerations. discusses collection processes employed study arthropods, factors determine systems specific projects, special problems posed by patchiness distribution which usual among animals application ranking other alternatives to census community do necessitate great labor counts.
