“…1 A). These observations are in line with previous studies of nurses (Crailsheim et al, 1996;Moore et al, 1998;Shemesh et al, 2007). By contrast, their same age full-sister bees that were caged on the broodless comb were significantly more active during the photophase (Fig.…”

The social environment influences the circadian clock of diverse animals, but little is known about the functional significance, the specifics of the social signals, or the dynamics of socially mediated changes in the clock. Honey bees switch between activities with and without circadian rhythms according to their social task. Forager bees have strong circadian rhythms, whereas "nurse" bees typically care for the brood around-the-clock with no circadian rhythms in behavior or clock gene expression. Here we show that nurse-age bees that were restricted to a broodless comb inside or outside the hive showed robust behavioral and molecular circadian rhythms. By contrast, young nurses tended brood with no circadian rhythms in behavior or clock gene expression, even under a light-dark illumination regime or when placed with brood-but no queen-in a small cage outside the hive. This behavior is context-dependent because nurses showed circadian rhythms in locomotor activity shortly after removal from the hive, and in clock gene expression after ϳ16 h. These findings suggest that direct interaction with the brood modulates the circadian system of honey bees. The dynamics of rhythm development best fit models positing that at least some pacemakers continue to oscillate and be entrained by the environment in nurses that are active around the clock. These cells set the phase to the clock network when the nurse is removed from the hive. These findings suggest that despite its robustness, the circadian system exhibits profound plasticity, enabling adjustment to rapid changes in the social environment.

“…Flying insects achieve the highest mass-specific rates of aerobic metabolism in the animal kingdom (Crailsheim et al, 1996;Suarez et al, 1996). In the housefly Musca domestica, prevention of flight activity decreases metabolic rate and results in reduced oxygen consumption and ROS production; it also decreases levels of carbonylation of mitochondrial proteins, reduces loss of protein function, and increases life span (Ryan et al, 2000).…”

“…In the housefly Musca domestica, prevention of flight activity decreases metabolic rate and results in reduced oxygen consumption and ROS production; it also decreases levels of carbonylation of mitochondrial proteins, reduces loss of protein function, and increases life span (Ryan et al, 2000). Elevated levels of oxygen consumption and mass-specific metabolic rate have been documented in honey bee foragers (Neukirch, 1982;Crailsheim et al, 1996;Suarez et al, 1996), and it has previously been hypothesized that the progression of aging in worker bees is driven by intense flight (Neukirch, 1982). Yet, diutinus bees may also perform considerable metabolic work as they metabolize the colony's honey stores to produce heat over several months (Omholt, 1987).…”

Accumulation of oxidative stress-induced damage in brain tissue plays an important role in the pathogenesis of normal aging and neurodegenerative diseases. Neuronal oxidative damage typically increases with age in humans, and also in the invertebrate and vertebrate model species most commonly used in aging research. By use of quantitative immunohistochemistry and Western blot, we show that this aspect of brain senescence is largely decoupled from chronological age in the honey bee (Apis mellifera). The bee is a eusocial insect characterized by the presence of a reproductive queen caste and a caste of functionally sterile female workers that performs various alloparental tasks such as nursing and foraging. We studied patterns of oxidative nitration and carbonylation damage in the brain of worker bees that performed nurse tasks as 8-and 200-day-olds and foraging tasks as 20-and 200-day-olds. In addition, we examined 180-day-old diutinus bees, a stress-resistant temporal worker form that survives unfavorable periods. Our results indicate that nitration damage occurs only at low levels in vivo, but that a 60-kDa protein from honey bee brain is selectively nitrated by peroxynitrite in vitro. Oxidative carbonylation is present at varying levels in the visual and chemosensory neuropiles of worker bees, and this inter-individual variation is better explained by social role than by chronological age.

Summary — Nurses and foragers were observed around noon and around midnight during good and bad weather conditions. Foragers were very busy on sunny days with almost no periods of inactivity. More than 60% of the observation period around noon they spent outside the hive. When foragers were prevented from flight by the lack of light or by bad weather, they showed long periods that were defined as unproductive and trophallactic contacts were reduced. Nurses aged 7-9 days showed a less pronounced behavioural difference between day and night but were highly sensitive to weather alterations. They spent less than half of the time nursing the brood during bad weather conditions compared to good weather conditions, although there was no lack of pollen and honey in the colony. The same tendency was observed in other nurse-related activities. They were less often fed by other bees during days with bad weather conditions than during days with good weather conditions. These dramatic changes in behaviour could be observed even on the first day of rain. We presume that the decline of activity is at least partly caused by the diminishing flow of food within a colony.social behaviour / division of labour / weather / day and night INTRODUCTION
