Käfer des Naturschutzgebietes "Petite Camargue Alsacienne", Saint-Louis, Haut-Rhin, Frankreich (Carabidae, Staphylinidae, Curculionoidea) : kommentierte Artenlisten, Stand 2012.

Results of a number of ecological studies were analysed and used to compile an up-to-date species list of ground beetles as well as new species lists of rove beetle and weevil species for the Petite Camargue Alsacienne (PCA) nature reserve (Saint-Louis, Alsace, France). The lists were discussed and analysed with a view to species diversity and occurrences of the most common species as well as rare and/or endangered species. The lists of ground beetles, rove beetles, and weevils are based on eight (1991 to 2008), three( 1999, 2003 and 2008), and one (2008) survey years respectively. A total of 18 different sites representing nine habitat types were surveyed using pitfall traps in periods of between one and five years, depending on the sites. The total survey effort was 3323 trap-days for ground beetles, 1050 trap-days for rove beetles, and 98 trap-days for weevils. Since Luka et al. (1998) eleven new species of ground beetle have been confirmed at PCA, resulting in a total of 160 ground beetle species known to occur at PCA by 2011. All 176 rove beetle species as well as 50 weevil species (Curculionidae sensulato) represent new records for PCA. Three ground beeetle species, Agonum piceum (Linné, 1758), Amara littorea C. G. Thomson, 1857 and Harpalus subcylindricus Dej ean, 1829 are new records for Alsace. Seven rove beetle species, Alevonota rufotestacea (Kraatz, 1856), Atheta pervagata G. Benick, 1975, Bledius crassicollis Lacordaire, 1835, Callicerus obscurus Gravenhorst, 1802, Oxypoda brachyptera (Stephens, 1832), Oxypoda lurida Wollaston, 1857 and Quedius semiobscurus (Marsham, 1802) are also new records for Alsace; additionally, 50 weevil species are new records for Upper Alsace. All of the 50 weevil species collected had already been recorded in Alsace, however for some of the species few records had been available to date. Eight of the species recorded can be considered remarkable and add to the weevil fauna in Alsace. Of these, the following six species were caught in pitfall traps: Bagouslutulentus (Gyllenhal, 1813), Ceutorhynchus resedae (Marsham, 1802), Hylobius transversovittatus(Goeze, 1777), Mogulones abbreviatulus (Fabricius, 1792), Neophytobius quadrinodosus (Gyllenhal,1813) and Pelenomus commari (Panzer, 1794). Manual catches resulted in the capture of the two species Sitona waterhousei (Walton, 1846) and Hypera striata (Boheman, 1834). Following revitalisation and restoration activities, the PCA nature reserve, which is now under asemi-natural management regime, provides habitat for numerous endangered species. 35% of all recorded carabid species are red-listed in Switzerland (30 species) or in the German state of Baden-Württemberg (51 species). Among the weevils, 10 species (25 %) are red-listed in Germany (nationwide, Bavarian and Baden-Württemberg lists). The reserve demonstrates that, even within a densely populated and agriculturally utilised region, conserving the remnants of the former floodplain landscapes can indeed serve to maintain an extraordinary wealth of native fauna.
