Quantifying responses of dung beetle assemblages to cattle grazing removal over a short-term in introduced Brazilian pastures

摘要: Abstract Pasture management techniques may affect the biodiversity of insects beneficial to pastures, such as dung beetles. Cattle grazing removal over a short-term is widely used in introduced Brazilian pastures. However, impact this on beetles still unknown. This study evaluated taxonomic (species richness, abundance, biomass, species composition, Shannon, and Simpson indexes) functional (functional richness FRic, dispersion FDis, evenness FEve, community-weighted means trait values CWMs) beetle assemblages response cattle short-in We sampled beetles, with pitfall traps baited carrion, simultaneously pastures constant (control), one, three, five months after Aquidauana, Mato Grosso do Sul, Brazil. Taxonomic metrics FEve did not differ among control pasture treatments. found that one month maintain same CWM coprophagous diet from control, higher biomass relation control. Although removal, at least short-term, does cause negative diversity indexes, two important traits associated are negatively affected three removal. Thus, we suggest rotational can be useful strategy to, besides conserving grass, also diversity, consequently ecological functions performed by them.
