Lizards have been reported as important pollinators on several oceanic islands. Here we evaluate the potential role of Galápagos lava lizards (Microlophus spp.) as pollinators across their radiation. Over 3 years, we sampled pollen transport by 9 lava lizard species on the 10 islands where they are present, including 7 single‐island endemics. Overall, only 25 of 296 individuals sampled (8.4%) transported pollen of 10 plant species, the most common being Prosopis juliflora, Exodeconus miersii, Sesuvium sp. and Cordia leucophlyctis. At least 8 of these plant species were native, and none were confirmed as introduced to the archipelago. Despite the low overall proportion of individuals carrying pollen, this was observed in 7 of the nine lizard species, and on 8 of the ten main islands (Española, Fernandina, Floreana, Isabela, Marchena, Pinta, Santa Cruz and Santiago), suggesting that this is a widespread interaction. The results reported here support the potential role of lava lizards as pollinators across their radiation, although they may represent a relatively modest contribution when compared with birds and insects. However, we cannot discard that lizards may be ecologically significant for particular plant species and ecosystems given the specific climatic condition and functional diversity of each island.

熔岩蜥蜴在加拉帕戈斯群岛上作为传粉媒介的潜在作用。

据报道，蜥蜴是几个大洋岛屿上的重要授粉媒介。在这里，我们评估了加拉帕戈斯熔岩蜥蜴（Microlophus spp。）在其辐射中作为传粉媒介的潜在作用。在过去的3年中，我们对10个岛屿上9种熔岩蜥蜴的花粉运输进行了采样，包括7种单岛特有物种。总体而言，在296个样本中，只有25个（8.4％）运输了10种植物的花粉，其中最常见的是朱利氏Prosopis juliflora，Exodeconus miersii和Sesuvium sp。和Cordia白液菌。这些植物中至少有8种是本地植物，没有一种被确认是引入该群岛的。尽管携带花粉的个体总体比例较低，但在9个蜥蜴物种中的7个以及十个主要岛屿中的8个（埃斯帕尼奥拉，费尔南迪纳，弗洛里亚纳，伊莎贝拉，马切纳，品塔，圣克鲁斯和圣地亚哥）都观察到了这一点，这表明这是一个广泛的互动。尽管与鸟类和昆虫相比，熔岩蜥蜴的辐射作用相对较小，但此处报道的结果支持了熔岩蜥蜴在辐射过程中作为传粉媒介的潜在作用。但是，鉴于每个岛屿的特定气候条件和功能多样性，我们不能放弃蜥蜴对特定植物物种和生态系统可能具有重要生态意义的观点。
