	abstract = {This paper investigates the effect of brood parasitism in a dung beetle assemblage in an arid region of Spain. The study was conducted during the spring season (March-May 1994-1998) using mesh cylinders buried into the ground, filled with sand and with sheep dung on top. We quantified the proportion of nests containing larvae of parasitic beetles and their effect on host larvae survival. Experiments on the effect of parasitic larvae on host-larvae survival were conducted by placing scarab brood masses (raised from captive scarabs in the laboratory) in containers with and without aphodiid larvae. During the spring, dung desiccation is rapid, preventing aphodiids nesting in the dung, and forcing these species to adopt brood parasitism as a nesting strategy. Parasitic aphodiids were found in 12-47\% of scarab nests of three species. The incidence of brood parasitization was positively related with the number of brood masses contained in the nests, being also higher in the most abundant species. Field data and experiments showed that brood parasites significantly reduced host larvae survival from 74.8\% in non-parasitized nests to 8.8\% in parasitized nests. Because different rates of nest parasitization and mortality were caused by parasites, brood parasitism had a differential effect on different host species. Thus, brood, parasitism constitutes an important mortality factor reducing the reproductive success of the host species and potentially affecting the beetle abundance in the area.},

	abstract = {1. Brood parasitism is an interaction that negatively affects reproductive success of host species, some of which have evolved defences to reduce offspring mortality caused by the parasites. In this study, we analyse the responses to interspecific brood parasitism of a dung beetle species, Onthophagus merdarius, in which reproductive success is heavily affected by parasitic beetles. 2. We used a combination of field and laboratory experiments to approach this question. Manipulating the effect of the presence of brood parasites on host nesting showed that there were no differences between treatments in nest traits. This absence of responses of the host species might be related to how and when brood parasites localize host nests: brood parasites actively find host nests after the nests have been finished and the nest burrows sealed. 3. Although both the rate of parasitism and the mortality rate caused by parasites are very high on O. merdarius, the possibility of the host species to evolve defence strategies against brood parasites is probably constrained by resource limitation for nesting in the study area. Because brood parasitism and resource limitation act synergistically favouring small brood size and small brood-mass size, smaller individuals may be also favoured under these conditions in the study area.},
