Epizootic tipping points: Environmental viral feedbacks predict amphibian die-offs

The paper tracks ranavirus epizootics in wood frog breeding ponds to show that viral accumulation rates, not static host or environmental factors, predict die-offs.

Gene Flow and Recent Lineage Colonization Constrain Genetic Differentiation Despite Local Adaptation

The paper examines how gene flow and colonization affect genetic differentiation in wood frogs, finding that selection overcomes genetic drift despite recent colonization and connectivity.

A shared pathogen reservoir can tip widespread infection into mass mortality

The paper develops a compartmental model showing that waterborne viral concentration, not individual host susceptibility, drives mass mortality in infected wood frog populations.
