Seasonal Blowfly Distribution and Abundance in Fragmented Landscapes. Is It Useful in Forensic Inference about Where a Corpse Has Been Decaying?

摘要: Blowflies are insects of forensic interest as they may indicate characteristics the environment where a body has been laying prior to discovery. In order estimate changes in community related landscape and assess if blowfly species can be used indicators corpse decaying, we studied how it is affected by 7,000 km2 region during whole year. Using baited traps deployed monthly collected 28,507 individuals 10 calliphorid species, 7 them well represented distributed study area. Multiple Analysis Variance found abundance between seasons analyzed land use 4 (Calliphora vomitoria, Lucilia ampullacea, L. caesar illustris). Generalised Linear Model analyses these compared with descriptors at different scales only clear significant relationship summer C. vomitoria distance urban areas degree urbanisation. This explained more deviance when considering composition larger geographical (up 2,500 m around sampling site). For other no uses was found, therefore observed their patterns could result variables, probably small temperature. Our results suggest that cannot infer what kind decayed, least highly fragmented habitats, exception being vomitoria.
