![]() ![]() Using 1) ecological niche modeling with maximum entropy (Maxent), 2) relative. Unfortunately, this information is available for only a minimum fraction of all animal species. Where does a species live? How common is it? Where does it spend its inactive periods? These are basic questions about the biology of a species, which bring key information for application in conservation and management. This region requires urgent conservation programs, because the Pacific Tropical rainforest is threatened by human settlement, and resource exploitation in spite of its protected status. In total, 41 bat species are present in the Pacific Tropical rainforests and surrounding dry forests, at the new Parque Nacional Cerros de Amotape, in Tumbes. auritus is the first for the Pacific versant of the Andes. io is the first for Peru, while that of C. leporinus, are also first records for the western slope of Peru. These document the first confirmed records for the department of Tumbes. ![]() Here we report noteworthy range extensions of 12 bat species, including: Diaemus youngi, Chrotopterus auritus, Micronycteris minuta, Mimon crenulatum, Vampyrum spectrum, Chiroderma salvini, Enchisthenes hartii, Noctilio leporinus, Thyroptera discifera, Eptesicus chiriquinus, Rhogeessa io, and Myotis riparius. The bat fauna of the Pacific Tropical rainforest region in Peru is poorly known. Se recomienda utilizar el presente modelo como herramienta útil para futuras evaluaciones de la conservación de esta especie. El área prioritaria más importante identificada para la conservación de esta especie se sitúa al norte de Perú, entre los Departamentos de Tumbes y Piura. Se determinó las zonas de mayor probabilidad de ocurrencia para esta especie y se estimó el área de distribución mediante el método del polígono mínimo convexo (PMC). Se estimó un índice predictivo aceptable (0.970) para el modelo final. Basados en los 13 registros confirmados se construyó un modelo de hábitat de máxima entropía determinando previamente las variables ambientales de mayor importancia para el modelo. Presentamos el primer modelo predictivo basado en los registros conocidos y el primer acercamiento geográfico para la especie. La distribución, extensión de ocurrencia y el área de vida de esta especie no han sido esclarecidos completamente. Tomopeas ravus, el murciélago de orejas romas, se conoce solo de 13 localidades confirmadas en Perú y actualmente se encuentra listada como En Peligro (B2 ab (iii)) por la UICN. Therefore, it is essential to have this information to prioritize both their conservation and protection of the ISDTFM. On the other hand, only 1.97% of this forest is under some Natural Protected Area scheme. This situation could become even worse if planned energy and extractive activities take place. This forest is severely impacted and fragmented by the constant expansion of agriculture and new access routes. In some cases, there is altitudinal and latitudinal replacement between patterns A and B. We have identified three distribution patterns (A, B, and C) for the endemic fauna. The endemic fauna is represented by four amphibians, 28 of reptiles, 13 birds, and five mammals outstanding among them Synallaxis maranonica due to its CR. We report 143 woody flora endemics, with Coursetia cajamarcana, Parkinsonia peruviana, and Pradosia argentea, among the most important due to their Critically Endangered (CR) condition, according to the International Union for Conservation of Nature and Natural Resources. Based on a review of literature related to the biological diversity of the inter-Andean Seasonally Dry Tropical Forests of the Marañón valley (ISDTFM), located in the regions of Cajamarca, Amazonas, Piura, La Libertad, Ancash, and Huánuco (Perú), this study highlights the richness of endemic species of woody flora and tetrapod fauna, as well as addressing their threats and state of conservation. ![]()
