"We have been concerned about the rapid and irreversible changes associated with a rapidly increasing human population that is already over seven billion people," commented Weller. "Many people are familiar with the impact of rising temperatures and greater intensity of storms on humans, but have less understanding of the effects of these and other global changes on the foundation of our biological ecosystemsplants."
Focusing on a group of organisms such as plants may help provide us with insights into how such crucial organisms have responded to climate changes in the past and how they might respond to future changes. Moreover, since impacts occur from the cellular and molecular basis to the ecosystem and evolutionary scale, this Special Issue provides an excellent opportunity to synthesize the current knowledge of global change effects on a wide spectrum of aspects of plant biology, ecology, and evolution.
"Plant biologists work at different levels of organization with diverse approaches and techniques to address questions about global change," notes Suding. "What is the effect of global change on plants, and how are plants affected by global change? Can we forecast how change at the global scale may lead to biological change? Can we identify systems, processes, and organisms that are most vulnerable to global changes? Can we use this understanding to enhance resilience to global changes?"
In their introduction, the Special Issue editors emphasize that in a complex world there is need to integrate information across spatial and temporal scales as well as across levels of biological organization. The need to collaborate and share info
