ARTICLE Ongoing harlequin toad declines suggest the amphibian extinction crisis is still an emergency Biodiversity loss is extreme in amphibians. Despite ongoing conservation action, it is difficult to determine where we stand in overcoming their extinction crisis. Among the most threatened amphibians are the 131 Neotropical harlequin toads. Many o...
Anthropogenic biodiversity loss is extreme in amphibians. Despite ongoing conservation action, it is difficult to determine where we stand in overcoming their extinction crisis 1,2. Extinction risk is not equally distributed across amphibians 3-5. Among the most threatened amphibians are the 131 Neotropical harlequin toads (Atelopus), many of which...
Global warming is a great threat to biodiversity with negative impacts spanning the entire biological hierarchy. One of the main species’ traits determining survival at higher temperature is the thermal point at which an animal loses its ability to escape from deadly conditions (critical thermal maximum—CTmax). Variation in CTmax across species is...
The genus Elachistocleis consists of small to medium size species of Neotropical microhylids. It is the second largest genus of New World microhylids and an important component of the anuran diversity in the Neotropical region. Herein, based on morphological, acoustical, and molecular evidence, we describe two new species and their advertisement ca...
The genus Pipa is a species-poor clade of Neotropical frogs and one of the most bizarre-looking due to many highly derived anatomical traits related to their fully aquatic lifestyle. With their African relatives, they form the Pipidae family, which has attracted much attention, especially regarding its anatomy, reproductive biology, paleontology an...
