The palm Euterpe edulis is an important palm species for the extraction of palm heart, a highly profitable consumable product. Due to its importance, much research has been conducted around the ecology of this palm species. Nevertheless, information available on its reproductive ecology is quality-deficient and fragmented, resulting in misleading views of the pollination and reproductive ecology of E. edulis. Here we conduct the first thorough study assessing the relative dependence on animal pollination of E. edulis in Argentina, and conduct parallel detailed observations on floral visitors. Also, we integrate our results with those available for the species in the literature. Here we found that E. edulis has an ambophilic pollination system. However, in our study system, there was a predominance of wind pollination over insect pollination and the species can also set seeds in the absence of pollen. Also, our study shows in great detail the large diversity of insects visiting E. edulis, indicating the generalist pollination system of the species, where Hymenoptera and Diptera stand out in richness and frequency of visits. The palm represents a key resource for a wide diversity of insect visitors, but the palm does not rely on their efficiency to act as pollinators. The varied levels of reproductive dependence on animal versus wind pollination of E. edulis may be shaped by climatic and landscape conditions. Such alternative versatile strategies allow the species to guarantee the reproductive success under different ecological contexts.

棕榈紫红色是提取棕榈心的重要棕榈树，棕榈心是一种高利润的消费产品。由于其重要性，围绕该棕榈树种的生态学进行了大量研究。然而，关于其生殖生态学的可用信息质量低下且支离破碎，导致对食用大肠埃希菌的授粉和生殖生态学的误解。在这里，我们进行了第一个彻底的研究，以评估阿根廷对E.edulis的动物授粉的相对依赖性，并对花卉访客进行平行的详细观察。此外，我们将我们的结果与文献中可用于该物种的结果相结合。在这里，我们发现可食的E. edulis有一个亲环境的授粉系统。但是，在我们的研究系统中，风授粉比昆虫授粉占优势，并且该物种也可以在没有花粉的情况下结实种子。此外，我们的研究还非常详细地显示了访问E.edulis的昆虫的多样性，这表明该物种的多面授粉系统，其中膜翅目和双翅目在丰富度和访问频率上均脱颖而出。棕榈代表着众多昆虫来访者的重要资源，但是棕榈并不依赖于它们的效率来充当传粉媒介。繁殖对动物的依存度水平的变化与可食性大肠埃希氏菌的风授粉的关系可能受气候和景观条件的影响。这种替代性的通用策略使该物种能够保证在不同生态环境下的繁殖成功。
