“…In the field, bumblebees may regularly experience differences in the nutritional quality of their resources (Vanderplanck et al 2014). Poor nutritional quality alters foraging activity (Pankiw et al 2004) and influences physiological conditions (Stabler et al 2015), whereas high-quality diets could have a buffering effect of heat stress on colonies (Vanderplanck, Martinet et al 2019). In other insects such as fruit flies or beetles, feeding raises CT max by increasing the body mass of the organism or by improving nutritional or hydration status (Nyamukondiwa & Terblanche 2009;Chidawanyika et al 2017).…”

Climate plays a key role in shaping population trends and determining the geographic distribution of species because of limits in species' thermal tolerance. An evaluation of species tolerance to temperature change can therefore help predict their potential spatial shifts and population trends triggered by ongoing global warming. We assessed inter-and intraspecific variations in heat resistance in relation to body mass, local mean temperatures, and evolutionary relationships in 39 bumblebee species, a major group of pollinators in temperate and cold ecosystems, across 3 continents, 6 biomes, and 20 regions (2386 male specimens). Based on experimental bioassays, we measured the time before heat stupor of bumblebee males at a heatwave temperature of 40°C. Interspecific variability was significant, in contrast to interpopulational variability, which was consistent with heat resistance being a species-specific trait. Moreover, cold-adapted species are much more sensitive to heat stress than temperate and Mediterranean species. Relative to their sensitivity to extreme temperatures, our results help explain recent population declines and range shifts in bumblebees following climate change.

“…In addition to the direct effects of climate change on species distributions, climate change might also increase the chance of losing appropriate floral resources by differentially altering the phenology of bees and plants and increasing temporal mismatches between them (Schleuning et al 2016;Ogilvie and Forrest 2017). Though our understanding of this phenomenon is largely theoretical and based on model predictions, empirical work suggests that access to high-quality resources can mitigate the impact of heat stress (Vanderplanck et al 2019).…”

Managed honey bees as a radar for wild bee decline?

Wild and managed bees are essential for global food security and the maintenance of biodiversity. At present, the conservation of wild bees is hampered by a huge shortfall in knowledge about the trends and status of individual species mainly due to their large diversity and variation in life histories. In contrast, the managed Western honey bee Apis mellifera is one of the best studied and monitored insects in existence. Since similar drivers may be relevant for the decline of wild bees and losses of managed honey bees, this raises the possibility that monitoring of honey bees may help to detect threatened regions for wild bees, thereby fostering urgently required conservation measures. However, this possible relationship has not yet been explicitly tested for. Moreover, research currently focused on honey bees as a model species may yield important insights into wild insect susceptibility to stressors and vice versa. Here we use the bees of Europe as a model to show that managed honey bees are not suitable surrogates for detecting declines in wild bees. A direct comparison of the response of wild bees and honey bees to the same threats (nutritional deficiencies, parasites and pathogens, pesticides, and a changing climate) shows that, whilst some of their responses may be similar at the individual level, when considered at the reproductive level (individuals versus colonies), many of their responses diverge. These results reinforce the need for basic research into wild bee biology, the need for national monitoring schemes for wild bee populations, and the call for conservation actions tailored to the individual ecologies of wild bee species.wild bees / indicator species / species specific / sociality / populations

“…To minimize the impact of heat stress on localized populations, we support the establishment of multiple and connected highquality habitat to improve bumblebee conservation (Vray 2018). It has been shown that highquality resources can mitigate the effect of heat stress (Vanderplanck et al 2019). Our study also raises a question about the use of a single bumblebee species in studies focusing on environmental stressors (i.e., nutritional stress, pesticides, parasites).…”

Hyperthermic stress resistance of bumblebee males: test case of Belgian species

Thermotolerance has often been linked to species distribution for a diverse range of organisms. In the context of climate change, assessing heat resistance ability is useful for understanding potential future range shifts and the physiological response of populations. As bumblebee (Bombus ) populations have been declining for several decades with several documented range shifts, an assessment of the hyperthermic resistance of species is urgently needed. In this study, we measure in males the heat resistance of ten bumblebee species living in temperate regions (northwestern Europe) with a static temperature methodology to evaluate the time before heat stupor (THS) which corresponds to a chill coma. Our results on heat stress resistance show that not all species are affected in the same way to heat stress. The most widespread species, B. terrestris (median THS 395 min) and B. lucorum (median THS 257 min) are the least sensitive to hyperthermic stress. The resistance time of bumblebee males is up to 10 times longer than the THS for declining species such as B. jonellus (median THS 48 min) and B. magnus (median THS 58 min). We highlight the high interspecific variability of heat resistance in a morphologically homogeneous genus such as bumblebees. From a conservation point of view, our research highlights the urgency for assessing the heat resistance of different species since each one can display a species-specific thermal sensitivity that is likely linked to a risk of decline in the case of heat waves.
