Rodrigues, who’s spent over 40 years trekking through the wild, called it his toughest expedition yet. Over 12 days, the 14-person team, with help from the Brazilian military, climbed 6,200 feet to the peak—terrain so rugged that even the local Yanomami people rarely visit it.

This isn’t Rodrigues’s first groundbreaking discovery. Back in 2017, his team explored Neblina Peak, about 50 miles away, and uncovered another new frog species—Neblinaphryne mayeri. DNA testing revealed that these new two frog species shared a common ancestor 55 million years ago, a time before massive geological changes split the region into isolated peaks.

Geologist André Sawakuchi explained how rivers, shifting vegetation, and eroding mountains formed natural barriers, leaving species like these frogs stranded and evolving along separate paths. These findings show how geology directly influenced biodiversity in the

While scientists analyzed DNA and mapped evolutionary timelines, they also turned to the local Yanomami people for insights. Although the Yanomami don’t venture into the dangerous peaks, their knowledge of the forest floor provided valuable clues about environmental patterns.

The Yanomami described climate shifts and changes in plant life that supported scientific observations. They also emphasized the cultural importance of protecting this biodiversity, blending ancient wisdom with modern research.

Rodrigues believes this collaboration shows the need to merge traditional knowledge with science to improve conservation strategies. “We’re not just learning from frogs; we’re learning from people who’ve lived here for centuries,” he said.

The expeditions weren’t just about new frog species. Botanist Lúcia Lohmann, who joined the Imeri trip, collected over 1,200 plant samples, including 220 species that might be entirely new to science. She stressed the importance of documenting biodiversity as habitat destruction and climate change escalate threats.

“By understanding the past, we can predict the future and protect species before they disappear,” Lohmann explained. Her work highlights how ecosystems are interconnected and vulnerable.

While these discoveries are exciting, they also underscore how fragile the

continue to threaten isolated ecosystems like Imeri and Neblina. Rodrigues warns that without quick action, many new frog species could vanish before we even know they exist.

The researchers are pushing for stronger conservation policies and protected areas to safeguard these biodiversity hotspots. “It’s a race against time,” Rodrigues said, urging governments to balance development with ecological preservation.

Describing a new frog species isn’t as simple as spotting a frog and giving it a name. The process involves collecting data on its vocalizations, measuring its anatomy, and analyzing DNA. For N. imeri, genetic testing was done in South Korea, followed by physical studies in Brazil.

Rodrigues emphasized the painstaking process: “We mentor young scientists and triple-check our findings before publishing.” While N. imeri was officially recognized in 2023, specimens of the new frog species collected in 2017 are still under review.

The discoveries have inspired plans for another expedition in 2025 to the Tulu-Tuloi Range, about 120 miles from Imeri. Once again, the team will need military support to tackle the rugged terrain and search for more hidden species.

Rodrigues hopes this research will continue shedding light on Amazonian biodiversity. “We’re uncovering evolutionary mysteries that could reshape how we see life in the
