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.
To address the growing interest and expressed need for pollinator management strategies a special pollinator symposium was held at the 2017 annual conference of the Natural Areas Association, curated by William Carromero of the US Forest Service and Lis
In a pollen supplementation experiment, fruit or seed production by flowers exposed to natural pollination is compared to that following hand pollination either by pollen supplementation (i.e.
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
