We present an updated of the official checklist of mammals of Ecuador. We follow a taxonomic ordering for the suprageneric categories, but alphabetically for the lower levels. We incorporate and indicate the taxonomic changes that have occurred since the last version published in December 2021. For the elaboration of this list a we kept a constant...

Aim: Comprehensive, global information on species' occurrences is an essential biodiversity variable and central to a range of applications in ecology, evolution, biogeography and conservation. Expert range maps often represent a species' only available distributional information and play an increasing role in conservation assessments and macroeco...

Los bosques húmedos de las estribaciones occidentales de la provincia de Azuay están entre los menos estudiados del país y no existe información sobre sus especies de primates. A partir de estudios de campo realizados en diciembre 2019 y enero 2020 confirmamos que en esta área habitan dos especies: Alouatta palliata aequatorialis (Atelidae) y Cebus...

We documented the first case of albinism for Dasyprocta fuliginosa, based on an individual that we recorded near San Pablo de Kantensiya, in the province of Sucumbíos, Ecuador. In this report, we also include information on the perspective with regards to this finding of the Siekopai indigenous people, ancestral inhabitants of the sector.

Thesis
Full-text available
Within the mammals, primates are considered a well-known group for their richness and distribution; furthermore, it is currently one of the orders facing serious conservation challenges. Based on this, I carried out a study to evaluate richness (Chapter III), distribution (Chapter IV) and conservation issues (Chapters V and VI) of the primates of E...

Understanding the geographic distributions of primates is necessary to ensure effective conservation strategies. Nonetheless, many gaps persist in information regarding the range limits of platyrrhines. Leontocebus lagonotus is no exception; it is one of the least studied primates in Ecuador and its geographic limits are poorly known. We obtained 2...

In the search for knowledge of the history of Ecuadorian mammalogy, I found a publication from 1847 that had remained unknown. This is the description of a Phyllostomid bat referred by the name of Arctibius floresii. Although I have not determined the specific identity of this record, the publication has unique charac- teristics that are worth ment...

The study of biological diversity in defined geographical areas is important for the implementation of management plans and the identification of knowledge gaps, particularly in high-rich groups, such as bats, and areas with significant vegetation cover, such as the case of the Pastaza Province. In the present work, I report the presence of 99 spec...

Changes in the behavior of primates caused by habitat disturbance are important indicators of their survival ability in fragmented landscapes. In Ecuador, few studies have examined the effect of habitat fragmentation on primate behavior.

The Academy of Natural Sciences of Philadelphia houses the oldest of the natural history collections of the United States and the continent. Between 1911 and 1984 the collection received 137 specimens from Ecuador, most of them collected in 1911, by Samuel N. Rhoads, and between 1935–1936, by Eric Erskine Loch (part of the Andes-Amazon Expedition)....

Regional and local environmental conditions shape the habitat preferences of species. In tropical highlands, the regional effects of elevation and local effects of topography combine to shape environmental conditions and create drastically heterogeneous habitats. This is thought to strongly influence the habitat preferences of species in the region...

Fur chromatic disorders, which include albinism, leucism and melanism, are rare in mammals. Worldwide these atypical cases are naturally infrequent and poorly reported in the literature, particularly in pinnipeds. The knowledge available about colouration in mammals comes from studies in mice and other domestic mammals. Generally this information i...

Knowing whether a species has been extirpated, or if it ever inhabited a specific geographic area, has direct importance for planning conservation activities. The taruka ( Hippocamelus antisensis ) is one of the largest Neotropical mammals; it is distributed in the central Andes, and there are published records of this species in Ecuador. Recently,...

When the Iberian colonists arrived in South America in the late fifteenth century, they encountered a diverse and previously unimagined fauna. The unusual anatomy and behavior of these species intrigued the early explorers. In their reports they named the new-found endemic animals after the most analogous European species. In 1576, for example, Per...

The forests of the western Amazonia, from Colombia south through Ecuador, Peru and Bolivia, are home to at least 30 taxa of pitheciines of the genera Pithecia, Cacajao and Callicebus. The primary threat to these monkeys is habitat destruction, although hunting further threatens populations in some areas. One taxon in this region is considered criti...
