Marked Impacts of Pollution Mitigation on Crop Yields in China
Earth's Future, 2022 Abstract Plant growth and crop harvest are impacted by both climate change and air pollution. However, their relative importance in crop yields remains elusive, especially in heavily polluted regions. Here we develop crop yield prediction models, based on a large volume of historical crop data, as well as climate ...

Estimating crop pollinator population using mark–recapture method [PDF]
Apidologie, 2013 Xylocopa species are large solitary bees, which are effective pollinators of yellow passion fruit, a self-incompatible crop dependent on pollination for fruit production and economic viability. We tested the mark–recapture method to estimate these bees' population size in a passion fruit commercial orchard in Central Brazil.
