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 کاملInnate olfactory preferences in dung beetles.
The effects of insect larval diet on adult olfactory responses to host-plant or food volatiles are still debated. The induction of adult host preferences has been studied in insects with diverse ecologies, including parasitoids, flower-visitors and phytophagous species. We investigated this question for the first time in a coprophagous insect species. Larvae of the French scarab dung beetle Agr...
متن کاملLarge-scale spatial ecology of dung beetles
Recent modelling work shows that the composition of local communities can be influenced by the configuration of the surrounding landscape, but many of these models assume that all community members display the same type of extinction-colonization dynamics. I use Aphodius dung beetles to test the hypothesis that interspecific differences in habitat selection and dispersal capacity may translate ...
متن کاملA molecular phylogenetic analysis of the Scarabaeinae (dung beetles).
The dung beetles (Scarabaeinae) include ca. 5000 species and exhibit a diverse array of morphologies and behaviors. This variation presumably reflects the adaptation to a diversity of food types and the different strategies used to avoid competition for vertebrate dung, which is the primary breeding environment for most species. The current classification gives great weight to the major behavio...
متن کاملDung beetles use their dung ball as a mobile thermal refuge
At midday, surface temperatures in the desert often exceed 60°C. To be active at this time, animals need extraordinary behavioural or physiological adaptations. Desert ants, for instance, spend up to 75% of their foraging time cooling down on elevated thermal refuges such as grass stalks. Ball-rolling dung beetles work under similar thermal conditions in South African savannahs. After landing a...
