African dung beetle Onthophagus gazella Fabricius (Coleoptera: Scarabaeidae) esterase isozymes.
African beetles Onthophagus gazella from both sexes were analyzed by electrophoresis for an investigation of esterase isozymes using alpha-naphthyl propionate and methylumbelliferyl propionate as substrates. Only one of the esterases (Est. 6) reacted with one of the substrates (alpha-naphthyl propionate). Six areas of activity were found, two of them being polymorphic (Est. 3 and Est. 4). For p...
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...

متن کاملPotential distribution modelling, niche characterization and conservation status assessment using GIS tools: a case study of Iberian Copris species
Dung beetle populations, in decline, play a critical ecological role in extensive pasture ecosystems by recycling organic matter; thus the importance of their conservation status. Presence data available for Copris hispanus (L.) and Copris lunaris (L.) (Coleoptera, Scarabaeidae) in Comunidad de Madrid (CM), and BIOMAPPER, a GIS-based tool, was used to model their environmental niches. The so de...
متن کاملThe South American Dung Beetle Genus Ennearabdus Lansberge (Coleoptera: Scarabaeidae: Scarabaeinae: Eucraniini)
The South American endemic dung beetle genus Ennearabdus Lansberge is revised. Description, diagnosis and illustrations are presented for the only known species of the genus, E. lobocephalus (Harold). A lectotype is designated for Onthophagus lobocephalus Harold, the type species of Ennearabdus. The biology, biogeography, conservation status, and distribution based on the predictive distributio...
