Abstract:
Ecosystem services (ES) such as pollination are vital for the continuous supply of food to a growing human population, but the decline in populations of insect pollinators worldwide poses a threat to food and nutritional security. Using a pollinator (honeybee) exclusion approach, we evaluated the impact of pollinator scarcity on production in four brassica fields, two producing hybrid seeds and two producing open-pollinated ones. There was a clear reduction in seed yield as pollination rates declined. Open-pollinated crops produced significantly higher yields than did the hybrid ones at all po

Abstract:
<b>Background and aims</b> – Autonomous selfing is a potential strategy to overcome pollinator scarcity or unreliability, but the specific mechanisms of autonomous selfing need further study to clarify our understanding of this phenomenon. This study investigated the mechanism of autonomous selfing in a subalpine population of <i>Prunella vulgaris</i> (Lamiaceae), a species with didynamous stamens.<b>Methods</b> – We studied the floral biology, pollinator activity, and breeding system of <i>Prunella vulgaris</i> in a natural population. The short stamens and long stamens were removed separatel

Abstract:
In desert plants, outcrossing is frequently limited by pollinator scarcity, leading to a certain percentage of self-fertilization. However, research on the ecological adaptations of self-fertilized seeds remains limited. Gymnocarpos przewalskii Maxim, a Tertiary relict plant in the arid deserts of Northwest China, exhibits pronounced self-pollination. In this study, the population of G. przewalskii from the fifth regiment of Alar City was selected to explore its self-pollination types, self-pollination percentages, and ecological adaptations. We found that artificially cross-pollinated G. prze

Abstract:
Even though urban green spaces may host a relatively high diversity of wild bees, urban environments impact the pollinator taxonomic and functional diversity in a way that is still misunderstood. Here, we provide an assessment of the taxonomic and functional composition of pollinator assemblages and their response to urbanization in the Paris region (France). We performed a spring-to-fall survey of insect pollinators in green spaces embedded in a dense urban matrix and in rural grasslands, using a plant setup standardized across sites and throughout the seasons. We compared pollinator species

Abstract:
A decline in pollination function has been linked to agriculture expansion and intensification. In northwest Argentina, pollinator visits to grapefruit, a self-compatible but pollinator-dependent crop, decline by approximately 50% at 1 km from forest edges. We evaluated whether this decrease in visitation also reduces the pollination service in this crop. We analysed the quantity and quality of pollen deposited on stigmas, and associated limitation of fruit production at increasing distances (edge: 10, 100, 500 and 1000 m) from the remnants of Yungas forest. We also examined the quantitative a

Flowering plants that attract a diverse range of pollinators represent a generalist pollination system. Studying these plants provides valuable information about accessibility of floral resources to pollinators, which is particularly important in areas where scarcity of flowers limits pollinator populations.

The provision of pollination services by pollinators is threatened by declines in their abundance and diversity. The reduction in pollinator populations may result in a decline in plant species diversity. Research on insect pollinators is a significant topic of discussion among researchers worldwide, primarily due to population declines attributed to various stressors, including climate change and the scarcity of floral resources.

Abstract Invasive plants often occur at high densities and tend to be highly generalist in their interactions with herbivores, pathogens, mycorrhiza, endophytes and pollinators. These characteristics mean that invasive plants should frequently participate in diverse indirect biotic interactions with the surrounding community, mediated by their direct interaction partners (e.g. antagonists and mutualists). Indirect interactions play an important role in many ecological processes, yet we still lack a systematic understanding of the circumstances under which they influence the success and impacts

Date palm fruits have essential importance due to their high economic value, nutritional benefits, and contribution to food security in arid and semi-arid regions. The unfavorable climatic conditions, drought or water scarcity, inconsistent pollination, genetic factors, and nutrient deficiencies cause date fruits to remain unripe for a long time. Artificial ripening is hastening fruit ripening using various techniques and chemicals. Artificial ripening techniques are employed to ripen date palm fruits to reduce their spoilage and waste, enhance their quality, and extend their shelf life. There
