A recently developed specific radioimmunoassay for neuromedin B, originally isolated from porcine spinal cord, was used to investigate its distribution in rat and guinea-pig brain and gut. In both species, neuromedin B-like immunoreactivity was present in several regions of brain, and high concentrations occurred in the pituitary. The immunoreactivity was… (More)
Insect macroecology and conservation biogeography studies are disproportionately scarce, especially in the Neotropics. Dung beetles are an ideal focal taxon for biodiversity research and conservation. Using distribution and body size data on the ecologically important Phanaeini, the best-known Neotropical dung beetle tribe, we determined elevational… (More)
Agricultural expansion and intensification are major threats to global biodiversity, ecological functions, and ecosystem services. The rapid expansion of oil palm in forested tropical landscapes is of particular concern given their high biodiversity. Identifying management approaches that maintain native species and associated ecological processes within… (More)
With the largest part of diversity in the world absorbed by invertebrates, ignoring invertebrates in biodiversity surveys and monitoring of areas under conservation would give a strongly incomplete image. The poor knowledge of most invertebrate taxa and their enormous diversity limits most surveys to the better-studied groups. Hawkmoths (Lepidoptera:… (More)
1. Biodiversity is changing at unprecedented rates, and it is increasingly important that these changes are quantified through monitoring programmes. Previous recommendations for developing or enhancing these programmes focus either on the end goals, that is the intended use of the data, or on how these goals are achieved, for example through volunteer… (More)
After examining syntypes of Onthophagus cervicornis Kirby, 1825, previously considered to be a synonym of the North American Onthophagus striatulus (Palisot de Beauvois, 1809), we confirm the true identity and new synonymy under South Asian Onthophagus dama (Fabricius, 1798).
Responses to microhabitat are often neglected when ecologists sample animal indicator groups. Microhabitats may be particularly influential in non-passive biodiversity sampling methods, such as baited traps or light traps, and for certain taxonomic groups which respond to fine scale environmental variation, such as insects. Here we test the effects of… (More)
Dung beetles (Scarabaeidae: Scarabaeinae) have long held a fascination for both amateur naturalists and academic researchers, and for a relatively small group of insects (some 6,000 species) one might think that they have received a disproportionate level of attention. However, as this book clearly demonstrates they are indeed worthy of such interest. In… (More)
