Seasonal bee communities vary in their responses to resources at local and landscape scales: Implication for land managers

Context: There is great interest in land management practices for pollinators; however, a quantitative comparison of landscape and local effects on bee communities is necessary to determine if adding small habitat patches can increase bee abundance or species richness. The value of increasing floral abundance at a site is undoubtedly influenced by the phenology and magnitude of floral resources in the landscape, but due to the complexity of measuring landscape-scale resources, these factors have been understudied.
Objectives: To address this knowledge gap, we quantified the relative importance of local versus landscape scale resources for bee communities, identified the most important metrics of local and landscape quality, and evaluated how these relationships vary with season.
Methods: We studied season-specific relationships between local and landscape quality and wild-bee communities at 33 sites in the Finger Lakes region of New York, USA. We paired site surveys of wild bees, plants..., , Data file 'bee_abundance_richness_all_predictors_toarchive.csv':  abundance and richness of wild bees at 33 sites in the Ithaca region of New York, USA with 68 variables of site and landscape quality. Landscape quality variables include topography, landscape-scale floral resources, landscape configuration and composition, and insecticide toxic load. Site quality variables include soil characteristics (texture, fertility, bulk density, water content), plant species richness, plant community composition, and site-scale floral resources.
Please see README for a description of column headings in the data file ('bee_abundance_richness_all_predictors_toarchive_Mar2024.csv').
Missing values: For analyses of species richness, we excluded sites with zero abundance of wild bees (either due to compromised traps or poor-quality habitat). In the data file, these instances are indicated as richness of zero., # Data from: Seasonal bee communities vary in their responses to resources at local and landscape scales: Implication for land managers

In brief, we sampled abundance and richness of wild bees at 33 sites in the Ithaca region of New York, USA for two years and generated 72 variables of site and landscape quality. Landscape quality variables include topography, landscape-scale floral resources, landscape configuration and composition, and insecticide toxic load. Site quality variables include soil characteristics (texture, fertility, bulk density, water content), plant species richness, plant community composition, and site-scale ...
