The amphibian species Anomaloglossus tepequem was once considered abundant in the Tepequém region of northern Brazil in the late 1980s and early 1990s. However, despite extensive search efforts, the species has not been detected since 2011, raising significant concerns regarding its conservation status. This project aims to reassess the status of A. tepequem by conducting comprehensive field surveys, combined with the latest techniques such as acoustic monitoring and environmental DNA (eDNA) sampling. These surveys will focus on the Tepequém Tepui and its surrounding areas, investigating whether the species may still persist in previously unexplored sites or if it has been lost from the region entirely.

A key component of this project is the documentation of the ecology of A. tepequem, which remains poorly understood. There is limited information on the species’ vocalizations, activity period, and other ecological traits, which are crucial for its conservation. Through the use of acoustic monitoring, the project will aim to record and analyze the species’ calls, which are essential for understanding its mating behavior and habitat preferences. Additionally, the project will assess the species' activity patterns, including its period of activity (diurnal or nocturnal), to gain insights into its behavioral ecology. This information will be critical in designing effective conservation strategies, especially in relation to habitat preservation and species protection.

The project will also examine the ecological and environmental factors that may have contributed to the decline of A. tepequem, particularly considering the historical impacts of gold mining between the 1980s and 1990s. The project will also assess the current threats posed by human activity, such as tourism, which has increased in the region in recent years. By using advanced detection methods, the project aims to clarify whether A. tepequem still inhabits the area and to map its distribution in relation to these environmental changes.

In addition to focusing on A. tepequem, the project will also assess the broader amphibian community within the Tepequém region, including related species. This will provide insight into the biogeographical patterns affecting species distribution across the Guiana Shield, a region known for its high biodiversity. By updating the conservation status of A. tepequem, the project will contribute valuable information for future conservation strategies and inform the establishment of protected areas in the region.

Ultimately, the findings from this research will help guide conservation actions for A. tepequem and other threatened species in the Guiana Shield, offering evidence-based recommendations for local conservation policies. The project will also contribute to raising awareness about the importance of preserving this ecologically significant area and ensuring the long-term survival of vulnerable species.
