Age and phenology control photosynthesis and leaf traits in the understory woody species, Rhamnus cathartica and Prunus serotina

Dataset contains leaf physiological variables and leaf traits from Rhamnus cathartica (buckthorn) and Prunus serotina (Black cherry) measured in Summer 2019 at Macalester College's Ordway Field Station. All data were collected on understory individuals from 4 sites within the forest in late May and early July, 2019. We sampled from 'tree' individuals and seedlings of both species. All methods and measurement protocols are published in Heskel et al. 2022 in AoB-PLANTS, currently in revision.
