... is a secondary plant metabolite found in some nectars that affects foraging in pollinators. In honeybees, caffeine increases foraging and recruitment to mediocre food sources, which might benefit the plant, but potentially harms the colonies. For the largest group of social bees, the stingless bees, the effect...

...David Deslauriers; Jon C. Svendsen; Janet Genz; Alex J. Wall; Henrik Baktoft; Eva C. Enders; W. Gary Anderson ABSTRACT In many animal species, performance in the early life stages strongly affects recruitment to the adult population; however, factors that influence early life history stages...

...Elizabeth L. Franklin; Elva J. H. Robinson; James A. R. Marshall; Ana B. Sendova-Franks; Nigel R. Franks SUMMARY Learning is widespread in invertebrates. However, whether social insects improve their recruitment skills with experience is only beginning to be investigated. Tandem running is a one...

... ) tuned to the caloric benefits of floral resources. Using infrared thermography, we tested the hypothesis that forager motivation to recruit nestmates for a food source is positively correlated with T th . We trained bees to a sucrose feeder located 5–100 m from the nest. Recruiting foragers had...

Pectoralis muscle length trajectory and activity patterns were measured in vivo...

..., both of which recruit nestmates. Our experiments suggest that during exploration the ants deposit a long-lasting pheromone that elicits a weak recruitment of nestmates, while when exploiting food the ants deposit a shorter lasting pheromone eliciting a much stronger recruitment. We further investigate...

Therefore, the power output is entirely determined by muscle activity and strain trajectory, rather than recruitment of motor units with different contractile properties as in many other vertebrate muscle systems. Relative EMG intensity...

To improve our understanding, we manipulated the locomotor forces of trotting dogs and monitored the resulting change in recruitment of five extrinsic muscles of the forelimb: m. serratus ventralis thoracis, m. serratus...

We present the first data showing that recruiting meliponine foragers at feeders and inside nests regulate their thoracic temperature according to net food profitability. Using...

We propose that effective signal amplification by the phase-reversal phenomenon occurs when bees straddle a cell across which the phase reversal is expressed. Such a bee would...
