In dung beetles, spatial and temporal segregation is determined by the niche and evolutionary history of the species and is mediated by competition. Different functional guilds of dung beetles use this segregation to reduce competitive pressure and optimize usage of ephemeral resources. We sought to understand the spatial (open and closed areas) an...

The use of cover crops is a promising alternative to enable production on a sustainable basis and promoting food security, especially if it is possible to combine protein food alternatives with resources saving technologies, including water. The objective of this research was to evaluate the agronomic potential of cover crops for grain and biomass production under variable water regime. The experimental design was a randomized block with variable water regimes (main plot) and the sub plot with coverage crop (amaranth, millet or quinoa) evaluated at different phenological stages. The study was carried out in the experimental area of Embrapa Cerrados (Planaltina, DF), Brazil, in a Cerrado Rhodic Hapludox (Oxisol) clavey, A moderate. During the first 30 days after emergence, irrigation was uniform (148 mm) and, after this period, the plants were submitted to four water regimes (WR) lower (II, 217 mm), below average (MI, 386 mm), upper average (MS, 563 mm) and higher (SS, 647 mm).
