Responses of selected beetle families (Carabidae, Chrysomelidae, Curculionidae) to non-crop habitats in an agricultural landscape

چکیده
Abstract Agricultural intensification has caused a simplification of agricultural landscapes, accompanied by increasing field sizes and reduction non-crop habitats. To mitigate negative impacts intensification, it is necessary to understand what extent different habitats contribute the maintenance biodiversity in agroecosystems. Here, we compared taxonomic diversity three beetle families among four habitat types—wheat fields, grassy margins, wildflower-sown areas under power poles, permanent grassland fallows, an landscape western Germany. Carabidae were caught pitfall trapping, Chrysomelidae Curculionidae suction sampling. We found surprisingly little variation types, though rarefied species number tended be higher fallows margins than poles wheat fields. Nevertheless, assemblages differed substantially types. In Carabidae, dominated hygrophilous with poor dispersal ability as opposed all other types being open high ability. Curculionidae, pole islands from predominantly species, whereas fields clearly eurytopic species. Our results thus highlight need for combination conservation measures enhancing functional assemblages.

The importance of semi-natural landscape structures in an agricultural landscape as habitats for stenotopic spiders
The development of agricultural landscapes during the last decades has been characterized by an increase in management intensity, and a consequent decrease in the number and size of natural and semi-natural habitats. As a result, isolation of populations of stenotopic species of forests, shores, heathers, etc., has increased. This is a serious problem, especially for smaller invertebrates with ...

Natural habitats surrounding agricultural Þelds provide a source of natural enemies to assist in pest control. The boundaries among landscape elements Þlter some organisms attempting to cross them, resulting in differing communities within the landscape elements. Ground beetles are numerous and generally disperse by walking. These qualities make them excellent organisms for the study of boundar...

We studied the long-term (23-24 years) species turnover and succession of epigaeic beetle assemblages (Coleoptera: Carabidae, incl. Cicindelinae) in three remnant habitats [cottonwood (Populus spp.) and oak (Quercus spp.) stands, and old fields] that are embedded within highly urbanized areas in central Minnesota. A total of 9,710 beetle individuals belonging to 98 species were caught in three ...

Certainly, Carabidae, Curculionidae and Chrysomelidae are the beetle families that are most studied and the most inspiring for scientific papers. Those three families are also among the most numerous and present the most colorful beetles. Publications go from simple articles in the past to sophisticated papers using cladistics, molecular biology and statistics, in pure research or, for leaf-bee...
