Daily Patterns of Pollinator Activity, Differential Pollinating Effectiveness, and Floral Resource Availability, in a Summer-Flowering Mediterranean Shrub
Аннотация:(...) Lavandula latifolia open flowers and produce nectar uninterruptedly over daytime, and both flower production and nectar secretion rates are highest early in the morning and late in the afternoon. Pollen availability in the flower population, as estimated by the proportion of pollen-bearing, male-phase flowers, reaches a maximum in late afternoon, while nectar and sugar availability peak around the middle of the day. There was considerable variation both among major groups (hymenopterans, dipterans, lepidopterans) and among species within groups, in the timing of foraging at flowers (...)
