Shifts in the Abiotic and Biotic Environment of Cultivated Sunflower under Future Climate Change

Sunflower is a unique model species for assessing crop responses and adaptation to climate change. We provide an initial assessment of how climate change may influence the abiotic and biotic environment of cultivated sunflower across the world. We find...

Phylogeny and source climate impact seed dormancy and germination of restoration relevant forb species

For many species and seed sources used in restoration activities, specific seed germination
requirements are often unknown. Because seed dormancy and germination traits can be
constrained by phylogenetic history, related species are often...
