Daily temporal structure in African savanna flower visitation networks and consequences for network sampling

Abstract: Abstract. Ecological interaction networks are a valuable approach to understanding plant-pollinator interactions at the community level. Highly structured daily activity patterns are a feature of the biology of many flower visitors, particularly provisioning female bees, which often visit different floral sources at different times. Such temporal structure implies that presence/absence and relative abundance of specific flower-visitor interactions (links) in interaction networks may be highly sensitive to the … Show more

“…Furthermore, bees have been considered as common in low-latitude regions (Olesen & Jordano, 2002) and indeed they were the most common visitor in our study site. Our results also suggest that bees were consistent in their visits throughout the day, which differs from the behavior of other animals (Baldock et al, 2011). Another consideration is the thin line between parasitism and the socalled facultative mutualists, which could easily cross it and become parasites if a floral visitor does not offer a reward to the plant, again exhibiting a tendency to generalization is some species (i.e., visit many species -have many links).…”

“…We surveyed flower visitor-flower interactions in the plots in each transect once a month from June − October 2013, with an additional survey in January 2014 (yielding 6 months of surveys) between 08h00 and 15h00, to allow us to capture variability in flower visitor assemblages over space and time (Baldock et al, 2011;Stone et al, 1998). Surveys were conducted on warm, windless days.…”

“…The daily activity pattern of bees has implications for sampling protocols when attempting to analyze the details of pollinator networks. If the various pollinating species have different diurnal patterns, and respond differently to climatic factors, then the pollinator assemblage recorded could be specific to the immediate weather conditions and the time of day the sample is taken (Baldock et al 2011). …”
