Особенности суточной диеты Pelobates fuscus (Pelobatidae, Amphibia) в пойме р. Хопёр (Саратовская область)

Аннотация

Рассмотрена суточная диета Pelobates fuscus в локальных популяциях в пойме р. Хопёр. Показано отсутствие половых различий в суточной диете. Большую часть добычи составляют животные массой 10 – 25 мг и длиной тела 8 – 18 мм. По числу экземпляров доминируют перепончатокрылые (Hymenoptera) (70.8%), а по биомассе – жесткокрылые (Coleoptera) (52.1%). Число ежесуточно добываемых беспозвоночных обычно не превышает 15 экз. Самый низкий уровень потребления кормов – в апреле и октябре, наибольший – в летние месяцы.
