High thermal tolerance in high elevation species and laboratory-reared colonies of tropical bumble bees
<p>Bumble bees are key pollinators with some species reared in captivity at a commercial scale, but with significant evidence of population declines and with alarming predictions of substantial impacts under climate change scenarios. While studies on the thermal biology of temperate bumble bees are still limited, they are entirely absent from the tropics where the effects of climate change are expected to be greater. Herein we test if bees' thermal tolerance decreases with elevation and if the stable optimal conditions used in laboratory-reared colonies reduces their thermal tolerance. We assessed changes in the lower (CTMin) and upper (CTMax) critical thermal limits of four species at two elevations (2600 and 3600 m) in the Colombian Andes, examined the effect of body size, and evaluated the thermal tolerance of wild caught and laboratory-reared individuals of B. pauloensis. We also compiled information on bumble bees' thermal limits and assessed potential predictors for broad-scale patterns. We found that CTMin decreased with increasing elevation while CTMax was similar between elevations. CTMax was slightly higher (0.84 °C) in laboratory-reared than in wild-caught bees while CTMin was similar, and CTMin decreased with increasing body size while CTMax did not. Latitude is a good predictor for CTMin only while annual mean temperature, maximum and minimum temperatures of the warmest and coldest months are good predictors for both CTMin and CTMax. The stronger response in CTMin with increasing elevation, and similar CTMax, supports Brett's heat-invariant hypothesis, which has been documented in other taxa. Andean bumble bees appear to be about as heat tolerant as those from temperate areas, suggesting that other aspects besides temperature (e.g., water balance) might be more determinant environmental factors for these species. Laboratory-reared colonies are adequate surrogates for addressing questions on thermal tolerance and global warming impacts. </p>

Data from: Commercial Bombus impatiens colonies function as ecological traps for wild queens
<p>1. In response to anthropogenic environmental change, the cues that animals use throughout their lifecycle to optimize fitness may become unreliable, resulting in an ecological trap.</p> <p>2. Here we investigated whether commercial bumble bee (Bombus impatiens) colonies managed for early spring crop pollination act as ecological traps for wild nest-searching Bombus queens by subverting their natural nest usurpation behavior.</p> <p>3. An average of 10 dead wild queens were recovered from each standard colony during the two-week period of the experiment, but colonies with queen excluders were successful in preventing wild queen deaths. The use of queen excluders did not impact colony performance in terms of resident queen survival, colony reproduction, colony weight gain or worker body size.</p> <p>4. Sites where wild nest-searching queens were small had higher rates of failed usurpation, suggesting smaller-sized queens are disproportionately at risk from failed usurpation. Furthermore, sites where commercial colonies without queen excluders were introduced for spring crop pollination had fewer bumble bee visits to a later-blooming crop compared to sites without commercial colonies.</p> <p>5. Synthesis and applications. Our findings reveal a novel mechanism by which commercial colonies can negatively impact wild bumble bee populations and their pollination services. At the same time, we demonstrate a simple and inexpensive risk mitigation tool – a queen excluder – was 100% effective at eliminating this risk without compromising colony performance. Commercial colonies used outdoors during the bumble bee nest-searching period should be fit with queen excluders to prevent negative impacts on wild pollinator communities and their services.</p>
