Can polyploidy confer invasive plants with a wider climatic tolerance? A test using Solidago canadensis

Polyploidy can cause variation in plant functional traits and thereby generate individuals that can adapt to fluctuating environments and exploit new environments. However, few empirical studies have tested for an association between ploidy level and climatic tolerance of invasive cytotypes relative to conspecific native-range cytotypes. Here, we used an invasive plant Solidago canadensis to test whether invasive populations had a higher proportion of polyploids, greater height and stem-base diameter, and occupied a wider range of climatic conditions than conspecific native-range populations. We also tested whether the invasive populations had overcome genetic founder effects. We sampled a total of 80 populations in parts of the invaded range in China and the native range in North America for in situ measurements of plant height and stem-base diameter in the field and for population genetic and cytotype analyses. To examine climatic correlates, we augmented our field sampled data with o..., Sampling and functional trait measurement
To identify occurrence locations of S. canadensis in China and North America, we conducted field surveys in summer and autumn for the period 2013-2016. We sampled a total of 2,051 S. canadensis individuals in 19 native and 61 invasive populations. The number of individuals sampled per population ranged from five to 33. The native range in North America was represented by 577 individuals while the invaded range in China was represented by 1474 individuals (Appendix 1). Any two sample populations were at least five kilometers apart. In each population, we sampled at random plants that occurred within a radius of 10 – 20 meters to minimize a potential bias due to environmental heterogeneity within a population (e.g. soil moisture and nutrients). To avoid sampling plants from the same genet within the same radius, we sampled plants that were at least two meters apart from each other.  . For each S. canadensis individual, we took in situ measurements..., , This README file was generated on 2024-02-21 by Junmin Li.
