Abstract Bumblebees are ubiquitous, cold‐adapted eusocial bees found worldwide from subarctic to tropical regions of the world. They key pollinators in most temperate and boreal ecosystems, both wild managed populations significant contributors agricultural pollination services. Despite their broad ecological niche at genus level, bumblebee species threatened by climate change, particularly rising average temperatures, intensifying seasonality increasing frequency extreme weather events. While some temperature extremes may be offset individual or colony level through regulation, bumblebees expected exhibit specific plastic responses, selection various traits, and/or range contractions under even mildest change. In this review, we provide an in‐depth up‐to‐date review on ways which overcome threats associated with current future global We use examples relevant fields physiology, morphology, behaviour, phenology, dispersal illustrate discuss contours new theoretical framework. Furthermore, speculate extent adaptive responses change influenced bumblebees’ capacity disperse track suitable conditions. Closing knowledge gap improving our understanding adaptability avoidance behaviour different climatic circumstances will necessary improve response models. These models essential make correct predictions vulnerability face human‐induced environmental changes unfold appropriate conservation strategies.

Animal pollination supports agricultural production for many healthy foods, such as fruits, vegetables, nuts, and legumes, that provide key nutrients protect against noncommunicable disease. Today, most crops receive suboptimal because of limited abundance diversity pollinating insects. pollinators are currently suffering owing to a host direct indirect anthropogenic pressures: land-use change, intensive farming techniques, harmful pesticides, nutritional stress, climate among others.We aimed model the impacts on current global human health from insufficient via diet.We used zonation approach estimate yield gaps animal-pollinated foods estimated proportion gap attributable based existing research. We then simulated closing "pollinator gaps" by eliminating portion total pollination. Next, we an agriculture-economic pollinator food production, interregional trade, consumption.

Beekeeping in Europe facing climate change: A mixed methods study on perceived impacts and the need to adapt according to stakeholders and beekeepers

The Science of The Total Environment, Год журнала: 2023, Номер 888, С. 164255 - 164255

Опубликована: Май 16, 2023

The beekeeping sector is suffering from the detrimental effects of climate change, both directly and indirectly. Despite numerous studies conducted on this subject, large-scale research incorporating stakeholders' beekeepers' perspectives has remained elusive. This study aims to bridge gap by assessing extent which stakeholders involved in European beekeepers perceive experience impacts change their operations, whether they had adapt practices accordingly. To end, a mixed-methods including in-depth stakeholder interviews (n = 41) pan-European beekeeper survey 844) was completed within frame EU-funded H2020-project B-GOOD. development informed insights literature interviews. results highlighted significant regional disparities perceived with Southern regions expressing more negative outlooks, while Northern reported favourable experiences. Furthermore, analysis revealed who were classified as 'heavily impacted' change. These lower average honey yields, higher colony winter loss rates stronger contribution bees pollination biodiversity, underscoring change's sector. Multinomial logistic regression determinants likelihood being indicates that experienced 10-fold heavily impacted compared beekeepers.

Advances and knowledge gaps on climate change impacts on honey bees and beekeeping: A systematic review

Global Change Biology, Год журнала: 2024, Номер 30(3)

Опубликована: Март 1, 2024

Abstract The Western honey bee Apis mellifera is a managed species that provides diverse hive products and contributing to wild plant pollination, as well being critical component of crop pollination systems worldwide. High mortality rates have been reported in different continents attributed factors, including pesticides, pests, diseases, lack floral resources. Furthermore, climate change has identified potential driver negatively impacting pollinators, but it still unclear how could affect populations. In this context, we carried out systematic review synthesize the effects on bees beekeeping activities. A total 90 articles were identified, providing insight into impacts (negative, neutral, positive) beekeeping. Interest change's impact increased last decade, with studies mainly focusing individuals, using empirical experimental approaches, performed at short‐spatial (<10 km) temporal (<5 years) scales. Moreover, environmental analyses based short‐term data (weather) concentrated only few countries. Environmental variables such temperature, precipitation, wind widely studied had generalized negative biological ecological aspects bees. Food reserves, plant‐pollinator networks, mortality, gene expression, metabolism impacted. Knowledge gaps included apiary beekeeper level, limited number predictive perception studies, poor representation large‐spatial mid‐term scales, analysis, understanding pests diseases. Finally, global are an emergent issue. This due their necessity implementing adaptation measures sustain activity under complex scenarios.

Warmer autumns and winters could reduce honey bee overwintering survival with potential risks for pollination services

Scientific Reports, Год журнала: 2024, Номер 14(1)

Опубликована: Март 25, 2024

Abstract Honey bees and other pollinators are critical for food production nutritional security but face multiple survival challenges. The effect of climate change on honey bee colony losses is only recently being explored. While correlations between higher winter temperatures greater have been noted, the impacts warmer autumn population dynamics age structure as an underlying cause reduced not examined. Focusing Pacific Northwest US, our objectives were to (a) quantify autumns winters foraging activity, overwintering cluster, spring losses, (b) evaluate indoor cold storage a management strategy mitigate negative change. We perform simulations using VARROAPOP model driven by future projections address these objectives. Results indicate that expanding geographic areas will extending flight times. Our support hypothesis late-season alters structure, skews towards older bees, leads risks failure in spring. Management intervention moving colonies facilities has potential reduce losses. However, gaps remain how optimize strategies improve different locations conditions. It imperative we bridge sustain beekeeping industry ensure security.

Anthropogenic climate change stands out as one of the primary forces expected to reshape Earth’s ecosystems and global biodiversity in coming decades. Sorbus alnifolia, which occurs deciduous forests, is valued for its ornamental appeal practical uses but reported be declining wild. Nevertheless, distribution this species’ suitable range, along with key ecological environmental drivers that shape habitat suitability, remains largely unknown. By analyzing 198 occurrence records 54 factors, we employed MaxEnt project S. alnifolia’s current future suitability. Our results showed annual precipitation (37.4%), normalized difference vegetation index (30.0%), August water vapor pressure (20.8%), temperature range (3.4%) were most significant variables explaining requirements. The habitats primarily scattered across eastern central China. Under projected climatic conditions, total expanse potential increase. However, expansion involves low-suitability habitats, whereas moderately highly are likely shrink, especially southern lower-altitude regions Based on these findings, propose several conservation strategies support long-term sustainability alnifolia.
