Nutrition is a key aspect influencing honey bee health and overwintering. Since seasonality in southern temperate climates represents significant research gap, this study conducted long-term monitoring of bees the Mediterranean (Sassari, Italy). Specifically, individual weight, fat body, size measurements (head, thorax, abdomen, total body) were recorded monthly so to detect changes nutrient storage worker during an annual cycle. Data analysed according sampling date, climate (temperature, precipitation, daylength), flower diversity for nurse forager separately. The nutritional year-cycle generally followed nectar flow showed two critical timepoints: summer winter dearth. A short cessation activities late fall/early coupled with increase indicated presence bees. Precipitation was found play important role nutrition area through its impacts on colony demography plants particular illustrating how change could pose threat European populations future. These results provide valuable insights into dynamics Apis mellifera ligustica that support management decisions improve overwintering success prevent unnecessary losses.

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.

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.

Extreme heat poses a major threat to plants and pollinators, yet the indirect consequences of stress are not well understood, particularly for native solitary bees. To determine how brief exposure extreme flowering affects bee behaviour, fecundity, development survival we conducted no-choice field cage experiment in which Osmia lignaria were provided blueberry ( Vaccinium corymbosum ), phacelia Phacelia tanacetifolia ) white clover Trifolium repens that had been previously exposed either (37.5°C) or normal temperatures (25°C) 4 h during early bloom. Despite similar number open flowers floral visitation frequency between two treatments, female bees with heat-stressed laid approximately 70% fewer eggs than females non-stressed plants. Their progeny received quantities pollen provisions larvae consuming from significantly lower as adults. We also observed trends delayed emergence reduced adult longevity when consumed pollen. This study is first document short, field-realistic bursts host can indirectly affect pollinators their offspring, important implications crop pollination populations.

Honey bee colonies are often subjected to diseases, nutrition quality, temperature and other stresses depending on environmental climatic conditions. As a result of malnutrition, the level Vg protein decreases, leading overwintering losses. The values must be high for successful wintering, especially before wintering. If good is not reached, long winter period may cause an increase in colony Supplementary feeding essential sustainability when floral resources insufficient, as recent years with emerging climate changes. Furthermore, quality food sources or nutrients significant maintaining honey health longevity. This study examined changes HSP 70 proteins 6 groups 48 fed five different nutrients. fatty acids that present highest amount Cistus creticus (Pink rock-rose), Papaver somniferum (Opium poppy) mixed pollen samples were linoleic, palmitic cis-9-oleic acids. proline, lysine glutamic acid determined C. pollen.

A. m. jemenetica is the indigenous honeybee of Arabian Peninsula. It highly adapted to extreme temperatures exceeding 40 °C, yet important molecular aspects its adaptation are not well documented. In this study we quantify relative expression levels small- and large-molecular-weight heat-shock proteins (hsp10, hsp28, hsp70, hsp83, hsp90 hsc70 (mRNAs)) in thermos-tolerant thermosusceptible carnica forager subspecies under desert (Riyadh) semi-arid (Baha) summer conditions. The results showed significant day-long higher hsp mRNAs compared same Baha, were very modest both those Riyadh though jemenetica. also revealed a interaction between subspecies, which indicated milder stress conditions Baha. conclusion, hsp10, hsp70ab, hsp83 key elements adaptive nature local that enhance survival fitness high temperatures.

Abstract Plant genetic resources (PGR) underpin the security of global agriculture. Rapid climate change presents formidable challenges for ex situ and in PGR management programs that operate over extended timeframes. The U.S. Department Agriculture National Germplasm System (NPGS) maintains more than 605,000 accessions representing 16,300 plant species 20 genebank locations. These are maintained cold storage as seeds vegetative tissues must be periodically regenerated; or actively growing plants fields, greenhouses, screenhouses, vitro; some cases within reserves. complicated relationships between crops their growth environments present unique regarding maintenance under a changing climate. Here we potential effects on reproductive success, pollinators beneficial insects, pathogens pests, infrastructure considerations, wild populations NPGS We provide novel tool summarizes past US temperature precipitation data alongside future projections to guide ongoing planning genebanks throughout United States. A series case studies exemplify instances where has already impacted management. Ongoing improvements response require continued observations current effects, careful innovative planning, creative approaches ensure successfully conserved generations.
