- Abstract
For the 29 most common litter and soil nematodes in Hestehave beech forest the following information, derived from 12 monthly samples, is given: mean number and live weight per m² with percentage juveniles, females, gravid females and males; percentage distribution in litter, 0–3 cm soil, 3–6 cm soft; number identified per month; mean individual biomass; total increments per m² in numbers and biomass; annual oxygen consumption; calorific equivalents of annual biomass increments and oxygen consumption. Annual mean total nematodes per m², corrected for extraction efficiency, is 1,432,000 with a biomass of 370,000 μg m-2 and a total energy flow of 14,000 cal m-2 year-1. Calorific equivalent of biomass production is 3230 calm-s and of respiration 10,800 cal m-2, with total respiration 2,270 ml O2 m-2 year-1. Annual production is 20.7 per cent of total energy flow and energy flow 28.5 kcal g-1; these are discussed in relation to previous estimates for nematodes and other soil invertebrates.
