Effects of methylmercury bioaccumulation on survival of Columbia Spotted Frogs were modified by sex and length and were mediated by corticosterone (a glucocorticoid hormone) whereas effects of chytrid fungus were limited. ABSTRACT Amphibians have suffered widespread declines caused by many interacting factors whose effects are often difficult to ...

Global drivers of the conservation–invasion paradox
Abstract The conservation–invasion paradox (CIP) refers to a long‐term phenomenon wherein species threatened in their native range can sustain viable populations when introduced to other regions. Understanding the drivers of CIP is helpful for conserving threatened species and managing invasive species, which is unfortunately still lacking. We compiled

Occurrences of dust storms and long‐distance movement of dust across landscapes is constantly increasing in south Asia. This dust is expected to have profound impact on vegetation health and sustainability as dust may contribute to nutrient budgets of the forest ecosystems, while it could impart various stresses to the plants.

Fire occurrence increased with proximity to roads and villages, indicating that human access and activity are major drivers of fire risk. We analyzed spatial patterns of fire in relation to human settlements. Our findings highlight the need for fire management strategies that consider accessibility and human presence in conservation planning.
