The foraging activity of floral visitors is influenced by habitat conditions and abiotic factors. The aim of this research was to define the faunal composition of the visitor community in Solanum lycocarpum A.St.-Hil. (Solanaceae) and to evaluate the

We examined the abiotic factors and co-specific competition for food resources that regulate the foraging activity of Oxaea flavescens bees on Styrax camporum flowers. Foraging records were gathered during 20 min. periods at the beginning of each hou

Abstract. The spatial and temporal distribution of food resources, as well as the type, quantity, and quality of the foods stocked in the hive are the principal regulatory factors of the choice and intensity of floral resource harvesting by bees. We
