Abstract
Ecological determinants of a meadow community of Coleoptera Scarabaeoidea Laparosticti (Manche, France). Beetles belonging to the group of Scarabaeoidea Laparosticti represent an important component of grazed meadows, particularly in contributing to their structural biodiversity. They are indeed functioning elements that recycle organic matter coming from herbivore dejections. This study aimed at characterizing the whole assemblage of Coleoptera Scarabaeoidea Laparosticti and at determining respective influence of two main ecological factors, i.e. the type of herbivore (cow or horse) and the type of grazed meadow (meso-hygrophilous or xerophilous), on the distribution (in terms of presence/absence and abundances) of coprophagous beetles. Sampling were carried out in the "Reserve naturelle nationale du Domaine de Beauguillot" (Manche, France) during 2005 by using the standard trapping "Cebo-Superficie-Rejilla". A total of 12,621 individuals belonging to 26 species were collected. A strong effect of herbivore type was highlighted, as numerous species were found to be exclusively or mainly present in cow dung. The effect of meadow type slightly occurred, being important only in case of statistical interactions with herbivore type.
