Data on "Phenotypic, floristic, and anthropogenic drivers of the pollen niche of Amazonian stingless bees"

This page describes the datasets necessary to reproduce the results found in the study conducted by Pimenta et al. (2025), titled “Pollen niche of Amazonian stingless bees”, published in Biotropica.The available files from this study are: bioclim.txt, compover.txt, compunder.txt, global_data.txt, radam.csv, tree.txt, tree_codification.csv.bioclim.txt: Rows represent the colonies of Meliponini species studied. Columns represent variables as follows: Nest coordinates of Meliponini included in the study and values of bioclimatic variables from the WorldClim 2 database.• Long – Longitude in decimal degrees• Lat – Latitude in decimal degrees• Bio1 to Bio19 – Extracted values for each nest location (study areas) of the bioclimatic variables from the WorldClim 2 database, following the original measurement units.compover.txt and compunder.txt: Rows represent the colonies of Meliponini species studied. Columns represent botanical taxa collected by Meliponini bees. Pollen taxa lists were compiled from studies conducted in the Amazon following methods described in “Data assembly”. The lists of taxa collected by Meliponini contained pollen identified at different taxonomic levels, leading to the construction of two versions of a bee-pollen interaction matrix: Underestimated and Overestimated, corresponding to the compunder.txt and compover.txt files. The logic behind these two dataset versions is described in the “Data analysis” section.global_data.txt: Rows represent the colonies of a studied Meliponini species. Columns represent variables compiled from studies on bee-pollen interactions in the Amazon, including the addition of the average intertegular distance (DIT) of species included in this study. The DIT values were obtained from measurements of individuals deposited in the entomological collection of the National Institute for Amazonian Research.• references – Citation with author and year referring to the individual bee-pollen study data included in this study. The complete list of bee-pollen studies is located at the end of the article in the “Data Sources” section.• Species – Species included in this study. The names in the “Species” column do not follow the binomial system from Moure's Bee Catalogue, to facilitate phylogenetic tree codification using the tree.txt and tree_codification.csv files.• intertegular.distance – Intertegular distance values measured in specimens from the entomological collection of the National Institute for Amazonian Research. Corresponds to the average of three specimens per species.• Habitat – Environmental variable. Indicates whether the studied colony was located in a natural environment (“Wild”) or an urban environment (“Urban”).• latitude – Latitude of compiled studies in decimal degrees• longitude – Longitude of compiled studies in decimal degrees• sample.type – Substrate used for pollen sampling collected by Meliponini in the Amazon.• first.year – Year of pollen analysis studies of Meliponini. Some studies were conducted over multiple years. To construct a continuous variable, we opted to use the first year of each study.• n.corbicule – Binary variable (0 = No, 1 = Yes). Indicates whether the compiled dataset examined pollen found in the corbicula of a Meliponini specimen from the Amazon.• n.pollen.pot – Binary variable (0 = No, 1 = Yes). Indicates whether the compiled dataset examined pollen found in the pollen pot of a Meliponini colony from the Amazon.• n.honey.pot – Binary variable (0 = No, 1 = Yes). Indicates whether the compiled dataset examined pollen found in the honey pot of a Meliponini colony from the Amazon.• n.months – Number of months pollen sample collection occurred in compiled studies.• n.pollen.types – Count variable. Sum of pollen types found in Meliponini pollen collection studies in the Amazon. The logic used to construct this variable can be found in the “Data analysis” subsection of the “Methods” section.radam.csv: Rows represent forest inventory locations closest to the colonies of a studied Meliponini species. Columns represent tree species found in RADAM inventory areas. More information about the RADAM inventory can be found in the “Data assembly” section of the “METHODS” section.tree.txt: This file corresponds to the phylogeny used in this study. See figure s1 included in the supplementary material.tree_codification.csv: This file provides information on which rows in global_data.txt correspond to which species available in the phylogeny (tree.txt).
