Lab Projects

How do species losses affect the dynamics of wild ecosystems?

The Coyote Ridge biodiversity experiment: How do realistic and random species losses affect serpentine grassland 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?

Biodiversity and ecosystem services: How do remnant forests sustain rural livelihoods in southwestern Ethiopia?

Species widowhood and taxon substitution: Can mutualists survive the loss of their obligate partners?



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

Nitrogen pollution and exotics: How does nitrogen deposition influence plant invasions that threaten endemic-rich California serpentine grasslands?

Climate change and ecosystem services: How does sea level rise affect the ability of Pacific estuaries to buffer coastal nitrogen pollution?



Conservation training

UCSC Doris Duke Conservation Scholars Program: Diversifying conservation by mentoring future leaders in their undergraduate careers.



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

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

Adaptation planning: What can California’s agencies and land managers do with climate impact and vulnerability information to ensure effective ecosystem stewardship?

Ecosystem-based adaptation: How can ecosystem-based adaptation enhance societal resilience to climate change?

Anticipating species responses: Why are California valley oaks in decline, and what can they teach us about species conservation in a changing climate?



Past Projects
