Informal Work and Sustainable Cities: From Formalization to Reparation.

Informal workers produce economic, social, and environmental value for cities. Too often, policy elites, including those promoting sustainable cities, overlook this value, proposing formalization and relying on deficit-based framings of informal work. In this perspective piece, we bring critical research and community-produced knowledge about informal work to sustainability scholarship.

Trends in Ranavirus Prevalence Among Plethodontid Salamanders in the Great Smoky Mountains National Park.

Emerging pathogens are a potential contributor to global amphibian declines. Ranaviruses, which infect ectothermic vertebrates and are common in aquatic environments, have been implicated in die-offs of at least 72 amphibian species worldwide. Most studies on the subject have focused on pool-breeding amphibians, and infection trends in other amphibian species assemblages have been understudied.

Susceptibility of fish and turtles to three ranaviruses isolated from different ectothermic vertebrate classes.

Ranaviruses have been associated with mortality of lower vertebrates around the world. Frog virus 3 (FV3)-like ranaviruses have been isolated from different ectothermic vertebrate classes; however, few studies have demonstrated whether this pathogen can be transmitted among classes. Using FV3-like ranaviruses isolated from the American bullfrog Lithobates catesbeianus, eastern box turtle Terrapene carolina carolina, and Pallid Sturgeon Scaphirhynchus albus, we tested for the occurrence of interclass transmission (i.
