Beetles succession on different microhabitats of small mammals in Riyadh, Kingdom of Saudi Arabia

다국어 초록 (Multilingual Abstract)

The decay of small carcasses is considerably neglected although it may provide important forensic data. This study differentiates the beetle species correlated with rat, Rattus norvegicus and mouse, Mus musculus (L. 1758) carcasses placed in two different habitats at King Saud University in western Riyadh. Decay processes and beetle succession were analyzed from January to February 2018. We collected an average of 268.67 beetles belonging to nine species from eight families, including Histeridae, Dermestidae, Cleridae, Tenebrionidae, Staphylinidae, Coccinellidae, Melolonthinae, and Pyrrhocoridae. Collected specimens were identified morphologically and by molecular techniques based on the mitochondrial cytochrome oxidase subunit I (COI) gene. Their presence rose in the bloated and decaying stages of decomposition. The beetle communities differed between the two habitats. In addition, a distinctive beetle community was found in the decaying stage compared to the other stages. The lowest number of beetles was reported in the dry stage. The abundance of beetles was associated with carcass size (rat or mouse) and habitat type.
