Evaluation of Relative Abundance Techniques (RATs) for Monitoring Rodent Abundance and Predicting Rodent Damage in Rice Agroecosystems

open access: yesIntegrative Zoology, EarlyView.
Among the different relative abundance techniques, giving‐up density (GUD) indices during the early and maximum tillering stages of rice development, and burrow counts during post‐harvest showed the highest correlation with cumulative tiller damage caused by rodents.

Navigating Sovereignty and Marine Biosecurity: The Challenge of Regulating Visiting Naval Vessels in Global Ports

open access: yesGlobal Policy, EarlyView.
ABSTRACT Environmental security has traditionally focused on climate change, resource scarcity and environmental degradation as drivers of instability and conflict. Comparatively little attention has been given to environmental biosecurity despite biological invasions representing one of the most significant and irreversible forms of environmental ...

Insurance and the Challenge of Governing Risks Beyond National Limits

open access: yesGlobal Policy, EarlyView.
ABSTRACT Even as the legitimacy of states appears to derive ever more explicitly from nationalist claims, nation‐states and national economies remain deeply entangled. In the face of border‐spanning risks, governments face both rising pressures for self‐centered policies and demands for more extensive transnational collaboration.

The obsolescence of protected area categories in a polycrisis world

open access: yesConservation Biology, EarlyView.
Abstract Current global conservation models face significant limitations in addressing the global polycrisis, and the constraints of the International Union for Conservation of Nature protected area (PA) classification system are part of the issue. The principles of the new conservation paradigm—governance, equity, and interculturality—are not viable ...

Detection of trade in products derived from threatened species using machine learning and a smartphone application

open access: yesConservation Biology, EarlyView.
Abstract Illegal and unsustainable wildlife trade remains a major conservation challenge and is increasingly shifting to online marketplaces where monitoring is difficult. To address this gap, we used real‐world images from online platforms, enforcement seizures, and market inspections to develop a deep‐learning object detection framework to identify ...
