Plant-soil interactions during the native and exotic range expansion of an annual plant

Range expansions, whether they are biological invasions or climate change-mediated range shifts, may have profound ecological and evolutionary consequences for plant-soil interactions. Range-expanding plants encounter soil biota with which they have a limited coevolutionary history, especially when introduced to a new continent. Past studies have found mixed results on whether plants experience positive or negative soil feedback interactions in their novel range, and these effects often change over time. One important theoretical explanation is that plants locally adapt to the soil pathogens and mutualists in their novel range. We tested this hypothesis in Dittrichia graveolens, an annual plant that is both expanding its European native range, initially coinciding with climate warming, and rapidly invading California, after human introduction. In parallel greenhouse experiments on both continents, we used plant genotypes and soils from five locations at the core and edge of each range t..., , , # Data from: Plant-soil interactions during the native and exotic range expansion of an annual plant

This dataset contains two CSV data files, one for each experiment described in the study (native range and exotic range). Both data files have the same file structure and column headers as described below.

## Description of the data and file structure

Each row in the dataset represents one plant in the experiment, with data for the following column headers. Missing data are indicated with NA.
