In the context of global pollinator decline, little is known about the protection status and ecology of many species. This lack of knowledge is particularly important for Mediterranean protected areas that harbor diverse pollinator communities and are subject to considerable anthropogenic pressures. Calanques National Park (85 km2), which is located near Marseille (France), is dominated by Mediterranean low-vegetation habitats, such as phrygana and scrublands. These habitats offer favorable conditions for pollinator species due to the important amount of floral resources. Within a 10-yr period, we recorded bee (Hymenoptera: Apoidea: Anthophila), hover fly (Diptera: Syrphidae), and bee fly (Diptera: Bombyliidae) species and their interactions with the local flora through 10 field campaigns. We caught 250 pollinator species, including 192 bees, 38 hover flies, and 20 bee flies, for a total of 2,770 specimens. We recorded seven threatened bees (six near threatened and one endangered). Among the bee species, 47.9% were below-ground nesting species, and 54.7% were generalist species. Analysis of the pollination network showed that generalist and specialist pollinators do not share the same floral resources. The Cistaceae plant family (Malvales: Cistaceae) acted as a central node in the plant-pollinator network, interacting with 52 different pollinator species, which shows the importance of large open flowers that could be easily visited by both short and long-tongued pollinators in Mediterranean habitats. The occurrence of pollinator species and their ecological traits should strongly contribute to reinforcing the available information to provide or ameliorate the conservation statuses determined by IUCN Red List.

传粉者特定的丰富度及其与当地植物物种的相互作用：地中海栖息地的 10 年采样

在全球传粉媒介减少的背景下，对许多物种的保护状况和生态知之甚少。这种知识的缺乏对于拥有多种传粉媒介群落并受到相当大的人为压力的地中海保护区尤为重要。Calanques 国家公园（85 平方公里）位于马赛（法国）附近，以地中海低植被栖息地为主，如弗里加纳和灌木丛。由于大量的花卉资源，这些栖息地为传粉物种提供了有利条件。在 10 年的时间里，我们通过 10 次实地活动记录了蜜蜂（膜翅目：Apoidea：Anthophila）、悬停蝇（双翅目：Syrphidae）和蜂蝇（双翅目：Bombyliidae）物种及其与当地植物群的相互作用。我们捕获了 250 种传粉媒介，包括 192 只蜜蜂，38 只盘旋苍蝇和 20 只蜜蜂苍蝇，总共 2,770 个标本。我们记录了七只受威胁的蜜蜂（六只接近受威胁，一只濒临灭绝）。在蜂种中，47.9%为地下筑巢种，54.7%为通才种。对授粉网络的分析表明，通才和专业授粉者不共享相同的花卉资源。Cistaceae 植物科（Malvales：Cistaceae）作为植物-传粉媒介网络中的中心节点，与 52 种不同的传粉媒介物种相互作用，这显示了大型开放花朵的重要性，短舌和长舌授粉者都可以轻松访问这些花。地中海栖息地。
