Map of the central upper Amazon basin showing the known distributions of western Amazonian Atelopus related to A. spumarius. Red dots correspond to A. spumarius sensu stricto, yellow dots to A. pulcher, green dots to A. seminiferus, blue triangles to A. colomai sp. n.; stars in the respective colors indicate type localities. White squares correspond to populations of unsolved taxonomic status. Basemap shows major Amazonian river systems and relief.

For nearly four decades, harlequin toads, genus Atelopus, have suffered unparalleled population declines. While this also results in limited understanding of alphataxonomic relationships, these toads face an urgent need for advances in systematics to inform conservation efforts. However, high intraspecific variation and cryptic diversity have hinde...

... Atelopus colomai sp. n. is known from the Amazonian lowlands of Ecuador, ranging from ca. 240-1020 m a.s.l. Historically, A. colomai sp. n. was reported from less than 30 localities in Orellana and Pastaza provinces, all situated between the Río Napo and the Río Pastaza (Fig. 7). However, specimens collected by Rolf Blom- berg in 1937(NHRM RRB/1937) originate from "Zamora", which, by that time, was the name for large parts of the southern Ecuadorian and adjacent Peruvian Amazonian lowlands. Thus, the distributional limits south-and eastward remain uncertain. Throughout the last 20 years and despite intensive ...

Flying squirrels are nocturnal, gliding relatives of tree and ground squirrels (order Sci-uridae). Despite 49 species existing, literature on Asiatic flying squirrels is scarce, thus they are overlooked in conservation action plans. Recently, three species of giant flying squirrel (Aeromys tephromelas, Petaurista petaurista and Aeromys thomasi) wer...
