We present an updated list of bird species from Department of Loreto. The list is based on the review of specimens from scientific collections, historical records, publications, and field observations. We report 1040 species of birds in Loreto, 72 in some threat category, 72 migratory and 13 endemics to Peru. Percnostola arenarum, Pithys castaneus and Polioptila clementsi are endemics to Loreto. The families with the highest numbers of species are Tyrannidae, Thamnophilidae and Thraupidae. The list presented is highly reliable due to the support of about 81% of the species on specimens from scientific collections and only 1.5% from sighting reports by ornithologists. Bird species from Loreto represent about 55% of the total reported for Peru and in Passeriformes 52% of those estimated for the Amazonia. The distribution of reports shows that it is necessary to explore areas close to the r...

In this study, we present the species of the genus Gynoxys recorded in the department of Amazonas, Peru. From March 2021 to October 2023, a review of exsiccata preserved in national herbaria, virtual databases of international herbaria, and field collections in different localities was carried out. We report 22 species of Gynoxys in Amazonas, of which two are new records for Peru and six are first reports for Amazonas. The genus is mainly distributed in the southern part of the department, inhabiting mainly moorlands and high altimontane forests of the Yungas, mostly located above 2900 meters above sea level (m a.s.l).

COVID-19 hit the Amazonian indigenous communities of Peru for two consecutive years, forcing them to recover traditional knowledge, practices and strategies to combat it. We present the plant and animal species used by two Ticuna communities in the Peruvian Amazon during the COVID-19 pandemic, describing the preparation and administration of the preparations. The information was obtained from semi-structured interviews with men and women from the communities during the first two waves of the pandemic, from May 2020 to June 2021. The interviews were face-to-face, in the field work carried out in the communities, and virtual, using the telephone and messaging applications available in the communities or in the nearby major population centers. During the field work in Nueva Galilea, visits were made to the collection points of the plant species. Fourteen plant species and three animal speci...

In the last years the Awajún people, settled in the Río Cenepa watershed (Department of Amazonas, Peru) are struggling to defend their land from the impact of the mining activities in the Cordillera del Condor mountains. The myth of Kumpanan, an ancestor associated to the homonymous pick, located in the mining area, has been revitalized, with a new meaning, mirroring the current social and environmental contingency of the area. This contributes to rethink the linkages existing between «history» and «myth».
