متن کاملDung 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 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 کاملVariation in cross-sectional horn shape within and among rhinoceros beetle species
Sexual selection has equipped male rhinoceros beetles with large horns on their head and prothorax to aid in battle over access to females. Horns are used to pry and dislodge opponents from resource sites that attract females, so an optimal horn should be able both to withstand the high stresses imposed during fights, and to resist deflection in response to these loads. We examined the cross-se...
متن کاملHormonal control of male horn length dimorphism in the dung beetle Onthophagus taurus (Coleoptera: Scarabaeidae).
Male dung beetles (Onthophagus taurus) facultatively produce a pair of horns that extend from the base of the head: males growing larger than a threshold body size develop long horns, whereas males that do not achieve this size grow only rudimentary horns or no horns at all. Here we characterize the postembryonic development of these beetles, and begin to explore the hormonal regulation of horn...
