    Consumption of fresh and buried seed by ground beetles (Coleoptera: Carabidae)

  • Original language description

    Ground beetles (Carabidae: Coleoptera) are predators of the seed of herbaceous plants scattered on the ground but prefer that of certain species. Foraging beetles encounter both freshly dispersed and seed exhumed from the soil bank. The predation on seedfrom soil bank has never been studied and the effect of burial on seed acceptability is unknown. The preferences of two generalist granivorous carabids, Harpalus affinis and Pseudoophonus rufipes, we investigated by offering them fresh (stored frozen after dispersal) and buried (for 6 months in the soil under field conditions) seed of six common weed species. Significantly more of the buried seed of Tripleurospermum inodorum and significantly less of that of Taraxacum officinale was eaten than fresh seed. In four other weed species the consumption of both kinds of seed did not differ. The preferences were similar in both species of carabid. The change in preference probably occurred because the seed of T. officinale was partial decayed

    Spotřeba čerstvých a vykopaných semen semen střevlíkovitými brouky (Coleoptera: Carabidae)

  • Czech description

    Střevlíci (Carabidae: Coleoptera) jsou predátoři semen. Jedinci hledající potravu nalázají jak čerstvá, tak semena pocházející z půdní zásoby semen. Predace semen z půdní zásoby však nebyla nikdy studována. Sledovali jsme preference semen u Harpalus affinis a Pseudoophonus rufipes, za použití čerstvých a vykopaných semen šesti běžných druhů plevelů. Průkazně více byla konzumována vykopaná semena Tripleurospermum inodorum a průkažně více čerstvá semena Taraxacum officinale. U ostatních druhů semen nebylpozorován rozdíl ve spotřebě. Pokud si semena v půdní zásobě zachovají svoji kvalitu, mohou sloužit jako rovnocená nebe lepší potrava pro střevlíkovité než čerstvá semena.
