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 combined impacts of warming and nitrogen deposition in terrestrial ecosystems?



    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?
