Climate change poses a threat to organisms across the world, with cold-adapted species such as bumble bees (Bombus spp.) at particularly high risk. Understanding how respond extreme heat events associated climate well factors that increase resilience or prime for future stress can inform conservation actions. We investigated effects of within different contexts (duration, periodicity, and without access food, in laboratory versus field) on bee impatiens) survival tolerance. found both prolonged (5 h) nutrition limitation were negatively correlated worker thermal However, these acute stressors not long lasting (no difference tolerance among treatment groups after 24 h). Additionally, intermittent stress, which more closely simulates forager behavior leaving returning nest, was Thus, short respites may allow foragers recover from stress. Moreover, results suggest there is no priming effect resulting short- long-duration exposure - remained equally sensitive subsequent exposures. In field-caught bees, collected during warmer cooler conditions exhibited similar being allowed lab 16 h.

Advancing bee conservation in the US: gaps and opportunities in data collection and reporting

Frontiers in Ecology and Evolution, Journal Year: 2024, Volume and Issue: 12

Published: March 21, 2024

Introduction Bee conservation in the US is currently hindered by challenges associated with assessing status and trends of a diverse group >3000 species, many which are rare, endemic to small areas, and/or exhibit high inter-annual variationin population size. Fundamental information about distribution most species across space time, thus, lacking yet urgently needed assess status, guide plans, prioritize actions among geographies. Methods Using wild bee data from two public repositories representing contiguous US, we evaluated availability sufficiency for use assessments bees. We also examined number recorded each state proportion recent records (2012–2021). Results Although efforts monitor bees continue grow, there remains massive paucity data. Exceedingly few (0.04%)reported both sampling protocol effort, greatly limiting usefulness Few or locations have adequate publicly available support analyses trends, fewer than half sufficient delineate geographic range. Despite an exponential increase submissions since 2000s, only 47% were reported within last decade, may be driven how collected, reported, shared, reflect troubling patterns local large-scale declines extirpations.

Lack of thermal acclimation in multiple indices of climate vulnerability in bumblebees

Proceedings of the Royal Society B Biological Sciences, Journal Year: 2025, Volume and Issue: 292(2038)

Published: Jan. 1, 2025

Indices of climate vulnerability are used to predict species’ change based on intrinsic physiological traits, such as thermal tolerance, sensitivity and acclimation, but rarely is the consistency among indices evaluated simultaneously. We compared physiology queen bumblebees between a species experiencing local declines ( Bombus auricomus ) exhibiting continent-wide increases B. impatiens ). conducted multi-week acclimation experiment under simulated warming measure critical maximum (CT max ), minimum min metabolic rate water loss in each these traits. also measured survival throughout after tolerance trials. Neither acclimated temperature treatments by adjusting any trait. found conflicting patterns within species. that individuals with highest CT exhibited lowest following trial. Our study highlights inconsistent across multiple species, indicating studies measuring only one index may be limited their ability inform responses environmental change.

Climate change will alter Amazonian bumblebees’ distribution, but effects are species-specific

Frontiers in Bee Science, Journal Year: 2025, Volume and Issue: 3

Introduction Understanding how climate change affects the distribution of Amazonian bumblebee species is essential for their conservation and pollination services they provide. This study focuses on two poorly known species, Bombus brevivillus transversalis , evaluating future scenarios may alter suitable habitats in Brazilian Amazon. Identifying potential refugia vulnerable areas crucial developing targeted strategies. Methods Species models were applied using occurrence data from museum records field collections. Climatic suitability was projected under baseline period (1970–2000) periods (2021–2040 2041–2060) high-emission scenario (SSP5-8.5) IPCC AR6 report. An ensemble modeling approach combining five different algorithms used to predict stability, habitat loss, range expansion. Results By 2060, B. lose 41.6% its current habitat, with significant reductions northern coastal regions. Conversely, expected retain 89.5% range, showing a westward shift. New climatically emerge both particularly western Amazon, potentially serving as refugia. Discussion The findings highlight species-specific responses change, being more than .

Abstract As cities around the world expand, we urgently need to better understand drivers of urban biodiversity, especially for functionally important groups such as insect pollinators. In this study, gathered hoverfly and bumble bee pollinator observations from natural history collections community science initiatives 462 landscapes across 85 US metropolitan areas. We tested whether greenspace functions habitat by examining total area in an landscape predicted occurrence, that is, presence or absence species a landscape. Our study was designed determine there were differences between (i.e., greenbelts, nature reserves forest/grassland fragments) developed managed parks, cemeteries golf courses) their ability support diversity species. After accounting sampling biases using integrated occupancy modeling approach, found positive association native occurrence area. This implies with more higher diversity. On average, not associated area; however, response varied among species, several at‐risk bees showing association. contrast area, no greenspace. addition, proportion racial minority households negatively occurrence. is consistent hypothesis systematic, unjust policies neighborhoods has lasting negative impacts on biodiversity. conclusion, our results vital recommend preservation remnant improve greenspaces order promote conservation.
