Costa Rican researchers discover new species of frog in coffee plantations

Researchers in Costa Rica have discovered a new frog species living within coffee plantations, marking a significant addition to the region’s biodiversity. The newly identified amphibian, dubbed the “coffee frog,” is small, nocturnal, and measures no more than four centimeters in length. It was found in San Lorenzo de Tarrazú, a mountain village in the province of San José. The discovery was made by biologist Wagner Chaves-Acuña, who worked alongside experts from the University of Costa Rica and the National Research Council of Argentina. The frogs, which are green and brown with distinctive markings, were observed during their most active hours, nighttime. According to Chaves-Acuña, they can be heard singing while perched on coffee bushes. The scientific name of the species is Isthmohyla nacientes, and it has been informally referred to as the “coffee frog.” These tiny amphibians do not feed on coffee berries but instead consume small insects found in the plantation environment. Male individuals possess a translucent throat that expands during their brief, shrill calls. The new species thrives in shaded, moist conditions typical of coffee farms. However, Chaves-Acuña warns that the use of pesticides on coffee plants could pose a threat to these delicate creatures. He explained that chemical residues spread through air and soil, eventually reaching water sources where tadpoles develop. This raises concerns about the potential impact of agricultural practices on local ecosystems. The discovery took place in the context of ongoing efforts to document and protect Costa Rica’s rich biodiversity. The country is known for its extensive rainforests and diverse wildlife, yet many species remain undocumented. The identification of Isthmohyla nacientes adds to this growing body of knowledge and highlights the importance of preserving natural habitats even in areas dedicated to agriculture. The research team conducted fieldwork in collaboration with multiple institutions, emphasizing the interdisciplinary nature of modern conservation science. Their findings suggest that coffee plantations, often viewed primarily for economic output, may also serve as critical habitats for unique species. This underscores the need for sustainable farming methods that balance productivity with ecological preservation. The discovery has sparked interest among scientists and environmentalists alike. While some see it as a positive step toward understanding and protecting biodiversity, others caution against overestimating the resilience of such species in human-altered landscapes. The researchers hope their work will encourage further study and promote policies that safeguard both agricultural interests and native wildlife. Looking ahead, the team plans to conduct more detailed studies on the behavior, diet, and reproductive habits of the new frog species. They also intend to explore how changes in land use might affect its survival. As climate change and habitat loss continue to threaten global biodiversity, discoveries like this offer a glimpse into the complexity of life in even the most seemingly ordinary environments.
