The glass frogs are facing a critical threat due to climate change, becoming an important symbol of the challenges affecting biodiversity in Latin America.
According to a collaborative study between scientists from Ecuador, Mexico, and the United States, at least six species could become extinct in the coming decades due to the loss of climatically suitable habitats.
Researchers have observed that these amphibians, known for their transparent skin and high environmental sensitivity, are migrating to higher altitudes in an attempt to avoid rising temperatures.
However, this movement towards cooler areas has natural limitations that could result in a crisis with no return, especially in regions like Ecuador and Colombia.
The study points out that, before the end of the century, the glass frogs could run out of viable habitats due to the warming and transformation of the Andean mountain ecosystems. This exodus to the mountains is recognized as a last-resort tactic, but the mountains offer limited space for such migration.
In Colombia and Ecuador, the glass frog species inhabit small and vulnerable areas, many of which are not legally protected against threats like mining and agriculture. This fact increases their vulnerability to accelerated environmental changes.
Glass Frogs
Focusing on 69 species belonging to the genera Centrolene, Nymphargus, and Vitreorana, the researchers emphasize the susceptibility of these frogs to abrupt temperature and humidity variations, which are common in the fragile ecosystems of northern South America’s mountains.
The research predicts that, between 2061 and 2080, many populations of glass frogs could experience a drastic reduction in their distribution area, raising the risk of local and global extinction.
In addition to habitat loss, glass frogs play a crucial role in the ecological balance of the Andean tropical forests, where they help control insect populations.
This phenomenon of altitudinal migration, increasingly common among mountain species, raises questions about the frogs’ ability to find suitable climate refuges, given that only 36% of potential areas are protected.
The researchers make an urgent call to improve conservation policies and expand protected areas in the Tropical Andes to prevent the loss of biodiversity.
Due to their permeable skin, glass frogs are effective environmental indicators, alerting about the health of ecosystems. The decline in their populations could be an early indicator of broader ecological deterioration.
Currently, 44% of glass frog species are endangered, facing threats that include emerging diseases and habitat destruction.
The recent discovery of a new species in Ecuador highlights the region’s rich biodiversity, a natural laboratory for studying the effects of climate change.
Conserving the Andean and Amazonian ecosystems is essential to avoid significant biodiversity loss in the coming decades, as without adequate biological corridors, these species could face mass extinction.
