Mounting evidence suggests that climate change, agricultural intensification and disease are impacting bumblebee health contributing to species’ declines. Identifying how these factors impact insect communities at large spatial temporal scales is difficult, partly because species may respond in different ways. Further, the necessary data must span scales, which usually means they comprise aggregated, presence-only records collected using numerous methods (e.g. diversity surveys, educational collections, citizen-science projects, standardized ecological surveys). Here, we use occupancy models, explicitly correct for biases observation process, quantify effect of changes temperature, precipitation floral resources on site over past 12 decades North America. We find no genus-wide declines occupancy, but do strongly related only weakly or resources. also more likely be change ‘losers’ than ‘winners’ this primarily associated with changing temperature. Importantly, all trends were highly species-specific, highlighting genus community-wide measures not reflect diverse species-specific patterns critical guiding allocation conservation

ABSTRACT Bees are essential pollinators and understanding their ability to cope with extreme temperature changes is crucial for predicting resilience climate change, but studies limited. We measured the response of critical thermal maximum (CTMax) short-term acclimation in foragers six bee species from Greek island Lesvos, which differ body size, nesting habit, level sociality. calculated ratio as a metric assess capacity tested whether bees’ was influenced by size and/or CTMax. also assessed CTMax increases following acute heat exposure simulating wave. Average estimate varied among increased did not significantly shift treatment except sweat Lasioglossum malachurum. Acclimation averaged 9% it associated or Similarly, average increase exposure. These results indicate that bees might have limited enhance tolerance via prior exposure, rendering them physiologically sensitive rapid during weather events. findings reinforce idea insects, like other ectotherms, generally express weak plasticity CTMax, underscoring role behavioral thermoregulation avoidance temperatures.

Abstract Global climate change has been identified as a potential driver of observed insect declines, yet in many regions, there are critical data gaps that make it difficult to assess how communities responding change. Poleward regions particular interest because warming is most rapid while biodiversity sparse. Building on recent advances occupancy modeling presence‐only data, we reconstructed 50 years (1970–2019) butterfly trends response rising minimum temperatures one the under‐sampled North America. Among 90 modeled species, found cold‐adapted species far more often decline compared with their warm‐adapted, southernly distributed counterparts. Furthermore, post hoc analysis using species' traits, find range‐wide average annual temperature only consistent predictor changes. Species warmer ranges were likely be increasing occupancy. This trend results majority butterflies probability over last years.
