Influence of Matrix Elements on Prairie-inhabiting Curculionidae, Tenebrionidae, and Scarabaeidae in the Palouse

摘要: It is well established that the invertebra te community in cropland under conservation-t illage (consT) often enriched relat ive to conventional-ti llage (CT) systems. The question posed this research whether consT contributes maintenance of regional biodiversity and conservation prairie-inhabiting species agriculturally dominated landscapes contain prairie remnants. During 2002, we sampled grounddwelling beetle fauna remnant Palouse surrounding (under CT consT) region northwestern Idaho southeastern Washington. Biological diversity representative taxaCurculionidae (weevils), Tenebrionidae (darkling beetles) Scarabaeidae (scarab beetles)-is significantly higher than agricultural fields, while divers ity these groups fields intermediate found CT. Faunal similarity (Bray-Curtis Index) greater between prairie. Together, results indicate ConsT potentially improves preservation landscapes.
