Název v původním jazyce

Seasonal variation in seed predation by adult carabid beetles

Popis výsledku v původním jazyce

In many agroecosystems of the temperate region, granivorous ground beetles (Coleoptera: Carabidae) are the most important invertebrate predators of seeds after dispersal. The consumption of a particular species of seed differs between carabid species butseasonal variation in consumption has not yet been studied. Seasonal differences in the quantity of seed consumed by the carabids Harpalus affinis (Schrank) and H. distinguendus (Duftschmid) was studied in a cafeteria experiment. Adults were collected on five dates between April and November, and provided with seeds of 28 species of dicotyledonous herbaceous plants. Proportions eaten of the seeds offered (preferences) were nearly identical in both carabid species. Overall seed consumption increased from early spring until late June, then gradually decreased towards autumn. Despite this variation, the preferences on particular dates were essentially similar. Seasonal variation in carabid physiology and feeding experience thus influenced
