“…From available studies meeting our criteria, a mean of 0.372 ± 0.576 mg sugar/h/bee was calculated from 329 measurements taken from 243 bees (Cahill and Lustik 1976;Rothe and Nachtigall 1989;Goller and Esch 1991;Stabentheiner et al 2003;Kovac et al 2007; Online Resource 1, Table S1-4 Data used to estimate the distribution parameters for sugar required to meet resting metabolic rate (S R ) of honey bee nectar foragers in the RARI and RP models). We believe that these estimates for resting metabolism overestimate energy expenditure of resting bees in the hive during the growing season because bees in clusters tend to have lower metabolism than isolated bees (Southwick 1983;Fahrenholz et al 1989). Most bees from which resting metabolism was measured were isolated.…”

Recent concerns regarding potential effects of pesticides on pollinators have prompted regulatory agencies to estimate dietary ingestion rates for honey bees (Apis mellifera). The task is difficult because of the complex caste and food storage systems in honey bee colonies. Considerable data on the nutrition and energetics of honey bees have recently been collated. These data were used to parameterize a probabilistic model estimating nectar requirements of nectar foragers. Median estimates were more than 6× lower than the recommended median value from the North American government agencies, of 292 mg nectar/bee/day. The distribution of estimates had much greater variability than those of the agencies. The differences are due primarily to the disparate assumptions regarding how much time nectar foragers spend flying and foraging. Risk assessors considering honey bee dietary exposure should take account of current and emerging data providing insight into nectar forager dietary requirements, foraging activity, and feeding behavior.

“…Climatic conditions can shape developmental rates, nesting strategies, biotic interactions, and other processes that determine the relative costs and benefits of group formation (Blumstein et al, 2022;Fisher et al, 2021;Menzel and Feldmeyer, 2021;Moss and While, 2021;Wilson, 1971). Social living can give rise to emergent strategies for coping with climatic stressors (Arnold, 1988;Fahrenholz et al, 1989;Klok and Chown, 1999). Observed patterns in global biogeography support hypotheses linking climate to social evolution, with distributions of social organisms falling along gradients of temperature, precipitation, and climatic stochasticity (Jetz and Rubenstein, 2011;Lukas and Clutton-Brock, 2017;Purcell, 2011).…”

1.Climatic factors are known to mediate the expression of social behaviors. Likewise, variation in social behavior can dictate climate responses. Understanding interactions between climate and sociality is crucial for predicting impacts of climate change on animal populations. 2.These effects are particularly relevant for taxa like bees that exhibit a broad diversity of social states. An emerging body of literature aims to quantify bee responses to environmental change with respect to variation in key functional traits, including sociality. Additionally, decades of research on environmental drivers of social evolution may prove fruitful for predicting shifts in the costs and benefits of social strategies under climate change. 3.In this review, we explore these findings to ask two interconnected questions: (a) how does sociality impact vulnerability to climate change, and (b) how might climate change impact social organization in bees? In doing so, we generate predictions about the impacts of climate change on the expression and distribution of social phenotypes in bees. Furthermore, we emphasize that social and solitary bee populations could be differentially impacted by climate change due to important behavioral, physiological, and life history differences.4. We highlight important avenues for investigating evolutionary consequences of climate change for social bees and for bee social organization. Understanding linkages between social behavior and environmental conditions is essential for forecasting vulnerability and resilience to climate change across bee taxa.

“…The heat production rate of six workers (45 mW/g) is also reduced by the addition of a queen (to 27 mW/g) or of a brood in some capped cells (to 26 mW/g). In both cases, worker bees are immediately engaged in social contacts and are therefore calmer than without such engagement .…”

Calorimetric investigations of terrestric animals of smaller size were performed in (1) Calvet‐type isoperibol twin instruments of up to 100 mL in content, (2) a “poor man's calorimeter” of up to 24 L in volume, in single and twin setups for colonies of honeybees, stingless bees, bumblebees, and hornets, and (3) a roundabout flight calorimeter for smaller insects. Special questions of metabolism concerning sleep and heat output rates of different castes in honeybees or of increasing numbers of individuals in a group were of interest. The most simple animals in these investigations were soil‐living species like earthworms, woodlice, pill bugs, and carabid beetles; they were investigated for their routine heat production rates and the rates under the influence of the effective uncoupler of oxidative phosphorylation, pentachlorophenol. The highest animals were lacertide lizards and snails, which were monitored for their standard metabolism and for stimulated reactions, to gather information about their scope of metabolism.
