New frog species discovered in western Amazon

Scientists have identified a new frog species, *Adenomera varcena*, in the seasonally flooded forests of the western Amazon. The discovery emerged from field surveys that combined acoustic monitoring with genetic analysis, revealing a population that was previously indistinguishable from its close relatives based on morphology alone.

Molecular sequencing confirmed that *A. varcena* possesses a distinct DNA barcode, while recordings captured a call pattern not observed in other members of the genus *Adenomera*. The species inhabits low‑lying forest patches that become inundated during the rainy season, a niche that likely contributed to its cryptic nature. Researchers noted that the frog’s limited range and specialized habitat make it vulnerable to ongoing deforestation and the broader impacts of climate change across the Amazon basin.

The finding underscores the extent of undocumented biodiversity in the region and highlights the urgency of documenting and protecting such species before habitat alteration accelerates. Conservationists stress that continued scientific exploration is essential to inform strategies aimed at preserving the Amazon’s ecological integrity.
