This paper reports on two studies describing responses of abundance, diversity, and functional structure of arthropod communities to high-intensity, low-frequency cattle grazing in eastern North American pastures. The first study assessed the state of arthropod communities before and after discrete grazing events. Grazing negatively affected abundance, diversity, and taxonomic richness, but functional diversity and functional evenness were unaffected. Assemblages of spiders and parasitoid wasps characterized pre-grazing communities, while beetles and flies were common after grazing. The second study assessed how these same properties changed with increasing deferment after grazing, and in response to vegetation structure. Longer deferment periods maximized arthropod abundance. Shorter deferment periods optimized taxonomic and functional diversity. Wasps characterized the most diverse community observed after 32 days of deferment. Vegetation height was important to explaining community composition. Height, biomass, and percent litter cover accounted for 11.8% of variance. Landscape variables may also be important to explaining community composition.
