Data for: Integration of an invasive plant in hummingbird and flower mite networks is driven by ecological fitting and generalization

Most plant communities worldwide include exotic plants, which did not evolve with local organisms. The central goal of this study is to test if native organisms expanding to novel hosts are usually generalists or specialists. Here we studied a new association between hummingbirds, flower mites, and Musa velutina (Musaceae), an exotic plant native to Asia currently invading lowland forests in Costa Rica. Hummingbirds are pollinators, but flower mites feed on nectar without contributing to pollen transfer. Flower mites hitch rides on hummingbird beaks to colonize new flowers. To determine the original diet breadth of hummingbird and flower mite species, we assembled interaction networks including 33 native host plants, 14 hummingbird and 19 flower mite species. Transportation analyses show that flower mites’ colonization of native or exotic hosts is not constrained by hummingbird flight connections. We identified four hummingbird species visiting Musa velutina. DNA barcode analyses i..., Hummingbird plant interactions were recorded by combining data collected in this study with published records. Hummingbird flower mite interactions with host plants were identified by sequencing the DNA barcode CO1. Hummingbird visits to Musa velutina (Musaceae) were recorded using camera traps., , # Data for: Integration of an invasive plant in hummingbird and flower mite networks is driven by ecological fitting and generalization [https://doi.org/10.5061/dryad.9kd51c5t1](https://doi.org/10.5061/dryad.9kd51c5t1) ## Description of the data and file structure Garcia-Robledo_Alvarado_Readme file generated on 2024-Oct-12 ## GENERAL INFORMATION Date of data collection: 2023-2024 Geographic location of data collection: La Selva Biological Station, Puerto Viejo, Sarapaqui, Costa Rica ## DATA & FILE OVERVIEW #### File list * A_Data_Hand_infloresc_Musa_velutina_Oct_24_2023.csv: number of female and male hands in inflorescences of *Musa velutina.* * B_Matrix_humming_plants_Dec_02_2023.csv: Qualitative interaction matrix, presence/absence of hummingbird species visiting each plant species * C_Matrix_flower_mite_plants_2024.csv: Qualitative interaction matrix, presence/absence of flower mite species visiting each plant species * D_hummingbird connections pairs of plants.csv: Number ...,全球多数植物群落中均存在外来植物——这类植物并未与当地生物协同演化。本研究的核心目标为验证：拓展至新宿主的本土生物，通常为泛化种（generalists）还是特化种（specialists）。本研究聚焦蜂鸟、花螨与红蕉（*Musa velutina*，芭蕉科）之间的新型互作关系：红蕉为原产于亚洲的外来植物，目前正入侵哥斯达黎加的低地森林。蜂鸟为传粉者，而花螨仅取食花蜜，无法协助花粉传播。花螨通过搭乘蜂鸟的喙来扩散至新的花朵。为明确蜂鸟与花螨物种的原始取食广度，本研究构建了包含33种本土宿主植物、14种蜂鸟以及19种花螨的互作网络。迁移分析结果显示：花螨对本土或外来宿主的定殖，并未受蜂鸟飞行连接的限制。本研究共鉴定出4种造访红蕉的蜂鸟物种。DNA条形码（DNA barcode）分析方面…… 蜂鸟与植物的互作数据，通过整合本研究采集的数据与已发表记录获得。花螨与宿主植物的互作关系，通过对CO1基因DNA条形码进行测序得以鉴定。通过红外相机陷阱（camera traps）记录蜂鸟造访红蕉（*Musa velutina*，芭蕉科）的行为。 # 数据集说明：入侵植物整合进入蜂鸟与花螨互作网络的驱动机制为生态契合（ecological fitting）与泛化策略（generalization） https://doi.org/10.5061/dryad.9kd51c5t1 ## 数据与文件结构说明 Garcia-Robledo_Alvarado_Readme 文件生成于2024年10月12日 ### 基本信息 数据采集时间：2023-2024年 数据采集地点：哥斯达黎加萨拉帕基省波多黎各维约市拉塞尔瓦生物研究站 ### 数据与文件概览 #### 文件列表 * *A_Data_Hand_infloresc_Musa_velutina_Oct_24_2023.csv*：红蕉（*Musa velutina*）花序内雌性与雄性花的数量 * *B_Matrix_humming_plants_Dec_02_2023.csv*：定性互作矩阵，记录各植物物种是否被蜂鸟物种造访 * *C_Matrix_flower_mite_plants_2024.csv*：定性互作矩阵，记录各植物物种是否被花螨物种造访 * *D_hummingbird_connections_pairs_of_plants.csv*：植物成对的蜂鸟连接数量……
