How do interacting global changes affect the dynamics and biodiversity of terrestrial ecosystems?

Ecosystem responses to climate changes:

  • How are North America’s highest-elevation breeding birds affected by climate and biodiversity changes?
  • How are climate and land use changes affecting treeline and forest ecotones in central Mexico’s volcanic arc?
  • How have California desert plant communities changed over half a century? Nitrogen pollution and exotics: How does nitrogen deposition influence plant invasions that threaten endemic-rich California serpentine grasslands?

What are the implications for ecosystem stewardship of global, directional environmental changes?

Conservation practice: How can we effectively steward nature through climate change?

  • What can we learn from past avian conservation translocations to guide decisions about future assisted range shifts?
  • How can riparian restoration in California maximize benefits to coastal stream communities and their users?
  • Adaptation planning: What can California’s agencies and land managers do with climate impact and vulnerability information to ensure effective ecosystem stewardship?
  • How can we mitigate stressors in North American alpine ecosystems to increase their capacity to adapt to climate change?
  • Ecosystem-based adaptation: How can ecosystem-based adaptation enhance societal resilience to climate change?

How do species losses affect the dynamics of wild ecosystems?

Ecosystem multifunctionality: How does biodiversity change influence multiple ecological processes at multiple scales?
Community disassembly: How is species’ vulnerability linked to their ecological roles through traits?
