Ecosystem technology (ecotech): Harnessing natural processes to address global challenges
ScienceAdvances EngineeringSilliman, et al.
2026-05-06
Over the past 80 years, biotechnology has advanced agriculture, health care, and economic development by harnessing biological processes from the organism inward, i.e., from the organ system to the molecular scale. Today’s global challenges, including biodiversity loss, climate change, and pollution, demand a complementary technological expansion inspired by processes operating from the organism outward, i.e., at the levels of populations, communities, ecosystems, and the biosphere. Here, we present the components of this technological expansion through ecosystem technology, or ecotech. We propose a framework for ecotech to integrate elements of ecology, engineering, and earth science and to function as a practical and conceptual convergence accelerator.
Harnessing ecological theory to enhance ecosystem restoration
Current BiologySilliman, et al.
2024-05-06
Ecosystem restoration can increase the health and resilience of nature and humanity. As a result, the international community is championing habitat restoration as a primary solution to address the dual climate and biodiversity crises. Yet most ecosystem restoration efforts to date have underperformed, failed, or been burdened by high costs that prevent upscaling. To become a primary, scalable conservation strategy, restoration efficiency and success must increase dramatically. Here, we outline how integrating ten foundational ecological theories that have not previously received much attention — from hierarchical facilitation to macroecology — into ecosystem restoration planning and management can markedly enhance restoration success.
Rise of Ruppia in Chesapeake Bay: Climate change–driven turnover of foundation species creates new threats and management opportunities
PNAS EcologyHensel, et al.

lobal change has converted many structurally complex and ecologically and economically valuable coastlines to bare substrate. In the structural habitats that remain, climate-tolerant and opportunistic species are increasing in response to environmental extremes and variability. The shifting of dominant foundation species identity with climate change poses a unique conservation challenge because species vary in their responses to environmental stressors and to management. Here, we combine 35 y of watershed modeling and biogeochemical water quality data with species comprehensive aerial surveys to describe causes and consequences of turnover in seagrass foundation species across 26,000 ha of habitat in the Chesapeake Bay. Repeated marine heatwaves have caused 54% retraction of the formerly dominant eelgrass (Zostera marina) since 1991, allowing 171% expansion of the temperature-tolerant widgeongrass (Ruppia maritima) that has likewise benefited from large-scale nutrient reductions.
A large invasive consumer reduces coastal ecosystem resilience by disabling positive species interactions
Nature CommunicationsHensel, et al.

Invasive consumers can cause extensive ecological damage to native communities but effects on ecosystem resilience are less understood. Here, we use drone surveys, manipulative experiments, and mathematical models to show how feral hogs reduce resilience in southeastern US salt marshes by dismantling an essential marsh cordgrass-ribbed mussel mutualism.
