Summary: The chemical composition of floral nectar is influenced by various endogenous and exogenous factors, including flower stage, floral visitation, and pollen contamination. Nectar sugar and amino acid concentrations are related to flower stage and visitor presence, with higher levels found in older flowers. Pollen contamination enriches the amino acid profile of nectar.

Summary: To predict the quantity and quality of food available to pollinators in different landscapes, detailed data on plant flowering phenology and food resource production per unit area are necessary. The current knowledge on this subject is fragmented. This database represents the first compilation of data on various food resources produced by 1612 plant species.

Summary: In the context of climate warming, alterations in plant pollination and reproductive success due to increased air temperatures constitute a significant issue. Higher temperatures negatively affect floral traits and rewards, leading to reduced flower visitation by pollinators, which could in turn decrease plant pollination rates and reproductive success under global temperature increases caused by climate change.

Summary: This study evaluated the nectar response of two native forbs to warming and found that it reduced nectar volume, increased sugar concentration, and increased the number of flowers produced. These findings suggest that warming can induce changes in nectar characteristics and impact the nectar-feeding community.

Summary: Climate change is predicted to increase extreme events like summer droughts in temperate zones, affecting plant water availability and potentially disrupting plant-pollinator interactions. While effects of drought on plant-pollinator relationships are not well studied, it could alter interactions through changes in floral signals and rewards at the plant individual scale. This review synthesizes evidence on the impact of drought on floral signals and rewards and discusses their potential disruption of plant-pollinator relationships.

Summary: Management of roadside habitat is crucial for the conservation of declining pollinators, but insect mortality along roadsides can create an ecological trap. Runoff from deicing salt can increase soil salinity and nectar attractiveness, potentially exacerbating the ecological trap effect. However, the roadside soil salinity in this study did not reach the level to enhance the ecological trap effect.

Summary: The study found that the white-backed planthopper performed better at 25 degrees Celsius, while the brown planthopper performed better at 30 degrees Celsius. However, at high temperatures, the white-backed planthopper caused a reduction in oviposition and nymph performance of the brown planthopper. Interference competition enhanced ecosystem resilience to warmer temperatures predicted under global climate change through host plant defenses.

Summary: The study demonstrates that pollinators at high elevations prefer large ultraviolet floral guides, while showing no clear preference under reduced ultraviolet light. Flies only preferred large guides on bare substrate. Additionally, the contrast between ambient UV light and floral backgrounds enhanced the visibility of the guides, with flowers contrasting more with bare ground than foliage.

Summary: The study shows that increasing Al content reduces the mass change of passivating scale formation and prolongs the passivation duration of the alloy, benefiting the formation of AlNbO4 and AlTaO4, which enhance the oxidation resistance of the alloy. Fracture of scales generally occurs at a mass gain of around 15 mg center dot cm(-2) and leads to a transformation to linear oxidation.

Summary: This study investigated the effects of adding different free fatty acids (FFAs) to waxy, normal, and high-amylose maize starches during heating. The presence of FFAs resulted in the formation of amylose-lipid complexes (ALC) in the starches, which affected their physicochemical properties. The FFAs had varying effects on the viscosity and gel strength of the starches, with stearic acid showing the least impact. The functional attributes of the starch-FFA blends were influenced by factors such as ALC formation, melting temperature, and gelatinization temperature.

Summary: The wear resistance of binary transitional metal nitride coatings can be enhanced by doping with tungsten. Hf1-xWxN ternary coatings with various W content were prepared and the influence of W doping on hardness, toughness, and tribological properties was investigated. The results show that Hf0.27W0.73N coating exhibits high hardness and improved toughness, with low friction coefficient and wear rate at room temperature.

Summary: The study focuses on the mechanical properties and microstructural changes of the high magnesium content New 5083M alloy during stretch forming. The results show that the 5083M alloy exhibits superior mechanical properties compared to the commercial 5083 alloy at high temperatures, but complex-shaped cavities that may affect mechanical properties appear under high temperature and low strain rate conditions.

It identifies current biodiversity and future extinction hotspots, highlighting the urgent need for conservation actions. The findings suggest that most bee species in the region will experience range contractions and there is a risk of extinction. The study emphasizes the importance of including bees in conservation planning in the archipelago.

Summary: Disturbances alter biodiversity by their specific characteristics, including severity and extent, and their effects depend on community characteristics and habitat requirements. Knowledge of natural disturbances' impact on biodiversity has become increasingly important due to changes caused by human activities. Some taxonomic groups respond positively to disturbance, while others tend to respond negatively. Understanding these relationships is crucial for managing and conserving biodiversity in disturbed ecosystems.

Summary: This study explores the bidirectional relationship between interaction network structure, species richness, and gross primary productivity (GPP) based on data from plant-pollinator networks and satellite measurements. The results suggest that both the structure of the networks and the richness of pollinator species have significant effects on GPP. Additionally, the network structure influences the inter-annual variability of GPP. The findings highlight the importance of considering biotic interactions in understanding the B-EF relationship.

Summary: Capparis spinosa is a plant with nocturnal floral habit and high visitation by diurnal bees but scarce visitation by hawkmoths. The intrafloral sensory stimuli suggest strong historical selection by hawkmoths on C. spinosa, and the floral display seems maladaptive in its habitat.

Summary: While wild pollinators are crucial for global food production, they are currently not included in the commonly used environmental impact assessment method, Life Cycle Assessment (LCA), due to data limitations and compatibility issues. To address this gap, a Delphi assessment was conducted to obtain relative pollinator abundance estimates from 25 experts covering 16 nationalities and 45 countries. Based on the estimates, globally generic characterization factors (CFs) were developed to assess the impact of land use on wild pollinator abundance in LCA studies.

Summary: In this study, we examined the alpha- and beta-diversity of pollinators, flowering plants, and plant-pollinator interactions along the altitudinal gradient of Mt. Olympus in Central Greece. Our findings showed that the alpha diversity of pollinators, plants, and plant-pollinator interactions were dependent on altitude. We also found that the beta diversity of pollinators, hoverflies, bees, bumblebees, non-bumblebee bees, butterflies, and plants increased linearly with altitude.

Summary: Throughout history, migratory beekeeping with traditional and movable-comb hives has been practiced in various regions of Greece, particularly in the eastern mainland and Aegean islands. The purpose of this practice is to increase honey production and ensure the bee colonies' productivity in the following season. The transportation of hives is usually done at night, using pack animals, carriages, or boats.

Summary: Fire has significant impacts on ecological processes, including pollination, and the effects of climate change on fire patterns can have unpredictable consequences. This study investigates the effects of a severe wildfire on hoverfly pollinators in a Mediterranean island system. The researchers found that hoverfly abundance and species richness peaked in the first year after the fire, with larger, less specialized, and more diverse pollination networks. However, these effects declined over the next two years, highlighting the importance of long-term monitoring to understand the responses of natural communities to wildfires.
