Differential impacts of land use change on multiple components of common Milkweed (Asclepias syriaca) pollination success

Land-use change is one the greatest threats to biodiversity and is projected to increase in magnitude in the coming years, stressing the importance of better understanding how land-use change may affect vital ecosystem services, such as pollination. Past studies on the impact of land-use change have largely focused on only one aspect of the pollination process (e.g. pollinator composition, pollinator visitation, pollen transfer), potentially misrepresenting the full complexity of land-use effects on pollination services. Evaluating the impacts across multiple components of the pollination process can also help pinpoint the underlying mechanisms driving land-use change effects. This study evaluates how land-use change affects multiple aspects of the pollination process in common milkweed populations, including pollinator community composition, pollinator visitation rate, pollen removal, and pollen deposition. Overall, land-use change altered floral visitor composition, with small bees ha..., , , # Differential impacts of urbanization on multiple components of common Milkweed (Asclepias syriaca) pollination success

## Description of the data and file structure

The data presented in the paper by Rocokow et al. Impacts of Urbanization on Pollination Success for Common Milkweed. The data is divided into four txt files each containg data for a specifc analysis outlined in the paper.

The data in the files is as follows:

File 1 pollinator visistation

Description: The visitation rate from every insect survey conducted (total # of insects observed divided by time surveyed in minutes divided by the number of inflorescences present).

Data in each column:

Type: Habitat type, either natural (A) or developed (B).

visit: The calculated insect visitation rate from every survey conducted.

site: The site in which the survey was conducted. The site numbers correspond to the following site codes: WL=1, WP=...
