Removal rates of native and exotic dung by dung beetles (Scarabaeidae: Scarabaeinae) in a fragmented tropical rain forest.
Many studies have evaluated the effect of forest fragmentation on dung beetle assemblage structure. However, few have analyzed how forest fragmentation affects the processes carried out by these insects in tropical forests where their food sources consist mainly of dung produced by native herbivore mammals. With the conversion of forests to pastures, cattle dung has become an exotic alternative...
متن کاملMorphology and terminology of dung beetles (Coleoptera: Scarabaeidae: Scarabaeinae) male genitalia.
The external and internal male genitalia of 327 species of 11 tribes of the subfamily Scarabaeinae, including species of Deltochilini, Scarabaeini, Gymnopleurini, Ateuchini, and Coprini, among others, were examined.

متن کاملPhylogeny of the Oniticellini and Onthophagini dung beetles (Scarabaeidae, Scarabaeinae) from morphological evidence.
A phylogenetic study was conducted to hypothesize relationships of most of the genera of the Oniticellini and Onthophagini for the first time using morphological characters from a diverse array of external and internal sclerites. The monophyly and sister relationship of both tribes was found using Bayesian and parsimony analyses with heavily to moderately weighted data. An alternative hypothesi...

متن کاملNew Guinea Onthophagus: taxonomy of ten small, unicolored new species (Coleoptera: Scarabaeidae: Scarabaeinae).
The taxonomy of small, unicolor brown to black Papuasian species of the genus Onthophagus Latreille, 1802 is discussed. Two multi-species groups are defined in the nominotypical subgenus Onthophagus, one with broad and one with narrow dorsal eye foramina (O. acerus and O. kokodentatus groups, respectively). Twelve species are listed, keyed, and diagnosed. Ten of these are new species from Papua...
