Can ant-eating Zodarion spiders (Araneae: Zodariidae) develop on a diet optimal for polyphagous predators

Popis výsledku v původním jazyce

Little attention is paid to the behavioural and physiological adaptations of ant-eating predators. It is expected that there should be a strong selection for traits related to prey handling, leading to the evolution of morphological, behavioural and nutritional adaptations. Such adaptations may then entail trade-offs in handling and utilization of alternative prey. To investigate behavioural as well as nutritional adaptations and the occurrence of the corresponding trade-offs in two ant-eating spiders of the genus Zodarion [ Zodarion atlanticum Pekár &amp; Cardoso and Zodarion germanicum (C. L. Koch)], spiders are reared on two diets: ants (i.e. their preferred prey) and fruit flies (i.e. an alternative prey that is nutritionally optimal for euryphagous spiders). Food consumption is observed and several fitnessrelated life-history parameters are measured. Although spiders readily accept ants, more than one-third of 35 spiders refuse to consume fruit flies and starve.
