Journal: :Restoration Ecology 2022

The incorporation of conservation physiology into environmental management, particularly ecological restoration, is underutilized, despite the capacity such approaches to discern how populations respond challenges unpredictable and potentially inhospitable environments. We explore several examples where detailed mechanistic understanding physiological constraints keystone foundational species, ...

Critics of the market-based, ecosystem services approach to biodiversity conservation worry that volatile market conditions and technological substitutes will diminish the value of ecosystem services and obviate the "economic benefits" arguments for conservation. To explore the effects of market forces and substitutes on service values, we assessed how the value of the pest-control services pro...

With intensifying demands for food and biofuels, a critical threat to biodiversity is agricultural expansion into native tropical ecosystems. Tropical agriculture, particularly intensive agriculture, often supports few native organisms, and consequently has been largely overlooked in conservation planning; yet, recent work in the Neotropics demonstrates that tropical agriculture with certain fe...
