Dung Beetles and Microbial Decomposition of Dung
Dung beetles belong to the superfamily Scarabaeoidea, and are mostly within the subfamilies of Scarabaeinae and Aphodiinae. They are given their name because they feed partially or exclusively on feces. Each species of dung beetles can be classified as one of several types: rollers, tunnelers and dwellers. Rollers roll the dung into round balls, which are then used for brooding chambers or as a...
متن کاملNew screening test to predict the potential impact of ivermectin-contaminated cattle dung on dung beetles.
According to European Union recommendations, a test method has been developed to evaluate the effects of veterinary pharmaceuticals on dung feeding insects. This test method was evaluated with the dung beetle Aphodius constans by using fecal residues of ivermectin after a pour-on administration. Dung of different age (and thus containing different concentrations of ivermectin) as well as mixtur...
متن کاملEffect of dung burial by the dung beetle Bubas bison on numbers and viability of Cryptosporidium oocysts in cattle dung.
Cryptosporidium oocysts were inoculated into fresh dung (∼1.2×10(4) oocysts per gram wet weight) and fed to dung beetles to assess the effect of dung burial by the dung beetle Bubas bison on the distribution of the oocysts in small cores of soil in the laboratory. The experiment consisted of five replicates of each of two treatments; controls (dung but no dung beetles) and the experimental trea...
متن کاملA 'metaphising' dung beetle.
You may have seen the film Microcosmos, produced in 1996 by the French biologists Claude Nuridsany and Marie Perrenou. It does not star humans, but much smaller creatures, mostly insects. The filmmakers’ magnifying camera transposes the viewer into the world of these organisms. For me, Microcosmos is not an ordinary naturalist documentary; it is an exercise in metaphysics. One sequence in the f...
متن کاملBiogas production with horse dung in solid-phase digestion systems.
Experiments on methanogenesis from horse dung were conducted in laboratory-scale batch reactors in order to determine the substrate performance in a solid-phase digestion process, more specifically in terms of potential energy recovery and suitable process technology. Dung from a horse stable with straw bedding was used. The temperature was kept in the mesophilic range. In the percolation proce...
