Data associated with: A phylogenetic perspective on ecological specialisation reveals hummingbird and insect pollinators have generalist diets

Specialisation in food resource use is a crucial process that fosters species coexistence in plant-animal networks, contributing to the maintenance of biodiversity, ecological complexity, and community stability. Notably, although there is a vast literature on ecological specialisation in pollination systems, the evolutionary similarity among the plant species visited by particular pollinators has been largely ignored. Here, we apply a robust phylogenetic approach to analyse whether the evolutionary relatedness of plant species is a significant factor in mediating pollinator visits and how it relates to the morphology of interacting species. We quantified ecological and clade specialisation of hummingbird and insect species in three mutualistic networks from the Costa Rican highlands and associated these metrics with species traits. We found that hummingbirds were overall ecologically more specialised than insects (i.e. visited a less diverse set of plant species). However, when evaluat..., The study was conducted in central–southern Costa Rica on the Caribbean and Pacific slopes of the Talamanca mountains, a volcanic mountain range that forms the spine of the Central American Isthmus from central Costa Rica through western Panama. This area includes the Cerro de la Muerte, which has the largest extent of páramo in the country (09° 60' N, 83° 76' W). The páramo is a neotropical grass- and shrub-dominated ecosystem that occupies the cool and wet upper slopes of neotropical mountains. Field data collection was conducted at three sites of about 12 ha each: Cerro las Vueltas Biological Reserve, Cerro Sákira, and Cerro Buena Vista (hereafter Reserve, Sákira, and Buena Vista, respectively) at elevations between 3000 and 3400 m a.s.l. We collected data on plant-pollinator interactions as well as on abundance and morphological traits of interacting species. Because the two types of studied organisms (plants and mobile pollinators) differ in space use, different approaches for samp..., , **Data associated with: A phylogenetic perspective on ecological specialisation reveals hummingbird and insect pollinators have generalist diets**

This repository contains three folders, each of them includes *R* codes and the respective data files in csv format; some of these data files include cells with \"NA\", which means data not available. The folders are named: DSI & phylo signal, Index d' and Models.

**DSI & phylo signal**. It includes the *R* scripts “1_DSI pollination.R” where the DSI* index is calculated for each pollinator species at each of the three study sites and “2_Phylo Signal.R” where the phylogenetic signal of pollinator richness is calculated for the three studied communities.

\- The source files used in “1_DSI pollination.R” are:
