Local adaptation and phenotypic plasticity drive leaf trait variation in the California endemic toyon dataset

Premise of the study:
To survive climate change and habitat loss plants must rely on phenotypic changes to the environment, local adaptation, or migration. Understanding the drivers of intraspecific variation is critical to anticipate how plant species will respond to climate change and inform conservation decisions. Here we explore the extent of local adaptation and phenotypic plasticity in Heteromeles arbutifolia, toyon, a species endemic to the California Floristic Province.
Methods:
We collected leaves from 286 individuals across toyon’s range and used seeds from 37 individuals to establish experimental gardens in the northern and southern parts of toyon’s range. We measured leaf functional traits of the wild collected leaves, and functional and fitness traits of the offspring grown in the experimental gardens. We then investigated the relationships between traits and source environment.
Key results:
Most traits we investigated responded plastically to the environment, and some tr..., , , # Local adaptation and phenotypic plasticity drive leaf trait variation in the California endemic toyon dataset

This dataset contains the data used to answer the research questions 1. How do toyon traits vary along environmental gradients? 2. How do genetic differences and environmental maternal effects contribute to trait variation between individuals grown in a common environment and how does this trait variation relate to the source environment? 3. Are toyon individuals adapted to their local environment? 4. Are some traits more plastic than others and do maternal lines vary in plasticity? It contains the herbarium, seed, greenhouse, and two common garden data sets with climatic variables sourced from the Bioclim dataset.
