Résumé
Invertebrate populations and biomass were measured on the Jornada desert grassland study site, United States International Biological Program, Grassland Biome, over a period from July 1970 to October 1972. Samples were taken at appproximately monthly intervals from both grazed and ungrazed treatments using randomly placed quick traps and a D-Vac vacuum insect collector....Supplementary sampling with the sweep net, pitfall trap, and light trap revealed that quick trap sampling was inefficient for some taxa. At least five invertebrate families which were taken by supplementary methods were entirely absent from quick trap samples.
