During the 2015 volcanic crisis and eruption of Cotopaxi –one of Ecuador’s highest-risk volcanoes– an urgent issue arose concerning the integration of the 1:50,000-scale volcanic hazard map, developed in 2004, into digital applications supported by Geographic Information Systems. The incorporation of this lower-resolution map alongside newer, more detailed base cartography revealed critical inconsistencies between the drainage...

Bisphenol A diglycidyl ether (BADGE), a derivative of bisphenol A (BPA), is widely used in the manufacture of epoxy resins as well as a coating on food containers. Recent studies have demonstrated the adverse effects of BADGE on reproduction and development in rodents and amphibians, but how BADGE affects biological activity is not understood. To gain a better understanding of the biological effects of BADGE exposure during de...

Standardized classification methods based on quantifiable risk metrics are critical for evaluating extinction threats because they increase objectivity, consistency, and transparency of listing decisions. Yet, in the United States, neither federal nor state agencies use standardized methods for listing species for legal protection, which could put listing decisions at odds with the magnitude of the risk. We used a recently dev...
