Join Jenica Allen and Bethany Bradley to learn about new tools for identifying and prioritizing range-shifting invasive plants coming soon to a landscape near you.
Conifers are commonly planted in North America to provide year-round screening, as windbreaks or as focal trees in the landscape.
North American forests and forest management institutions are experiencing a wide range of significant ecological disturbances and socioeconomic changes, which point to the need for enhanced resilience.
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.
