    Description

    In June 1993, we collected 144 leaf litter samples from 36 plots (4 samples/plot) located in MOFEP forest sites 1, 2 and 3. Half of the plots were placed randomly on northeast-facing stands (ELT 18), and half randomly placed on southwest-facing stands (ELT 17). Arthropods were extracted using Tullgren funnels, and then sorted into morpho-species, counted, and measured. Out of 126 usable samples, we found 22 orders of arthropods, 547 morpho-species, 40,000 individuals, and 30 g of arthropod biomass. ANOVA showed richness, numbers, and mass were higher on northeast- than on southwest-facing plots, but diversity was lower. Diversity, and to a lesser extent, numbers and richness, were lower in site 1.
