Studies on population genetic differentiation are essential for understanding the ecological, biological, and behavioral aspects of species, as well as their diversification patterns and how populations evolve over time. The species Artibeus planirostris, one of the best-known Neotropical fruit bats, has a wide distribution. This species exhibits h...

The fundamental value of universal nomenclatural systems in biology is that they enable unambiguous scientific communication. However, the stability of these systems is threatened by recent discussions asking for a fairer nomenclature, raising the possibility of bulk revision processes for "inappropriate" names. It is evident that such proposals co...

Peropteryx pallidoptera is the newest described species of Peropteryx, know from only few localities in Ecuador, Peru, Brazil, Colombia, and Bolivia. Herein, we report new records of this species, and we show that P. pallidoptera has a wider distribution than known across the Amazon. Our records are based on field sampling and, mostly, on museum vo...

El capítulo presenta algunos elementos de análisis y juicio relevantes sobre la situación, tendencias y dinámica de la diversidad biológica y las contribuciones de la naturaleza para las personas, aunque no se dispone de suficiente información para un análisis profundo sobre el estado de la biodiversidad y los servicios ecosistémicos de la Región A...

Platyrrhinus guianensis is bat with a distribution restricted to the Guiana Region of South America in Guyana and Suriname. Herein, we report the southernmost record of this species, extending its distribution to Brazil in Brazilian Amazon. Our record indicates that the species have a larger geographical range that previously thought. Platyrrhinus...

The genus Saguinus comprises three principal clades that diverged in the Middle to Late Miocene. Their taxa are ecologically differentiated and allopatrically distributed. These clades were recently recognized as different genera, Saguinus, Tamarinus and Oedipomidas. In Tamarinus, the phylogenetic relationships among species/subspecies are poorly u...

A Área de Relevante Interesse Ecológico Javari-Buriti é uma Unidade de Conservação federal que esteve perto de completar 40 anos desde a sua criação e ainda ser considerada uma das áreas menos conhecidas da Amazônia brasileira. Em seu Artigo 1º, o Decreto nº 91.886 de 1985, determinou que “sob a denominação de Javari-Buriti, fica declarada Área de...

A Restauração de Ecossistemas, como estratégia integrada à conservação e uso sustentável, é fundamental para o reestabelecimento de serviços ecossistêmicos essenciais à vida e economia, o enfrentamento das mudanças climáticas com o sequestro e estoque de carbono, a redução da perda da biodiversidade e a melhoria da qualidade de vida das pessoas. O...

The historical biogeography of the major South American forested biomes has long intrigued scientists. Paleoclimatic events during the last 130 thousand years promoted connections between forested biomes in the Neotropical region, leading to disjunct distributions of some of the biota. In this context, MacConnell’s Bat, Mesophylla macconnelli, appe...

Although the Amazon has the greatest diversity of primates, there are still taxonomic uncertainties for many taxa, such as the species of the Saguinus mystax group. The most geographically broadly distributed and phenotypically diverse species in this group is S. mystax, and its phenotypic diversity has been recognized as three subspecies—S. mystax...

Bats are the second most diverse mammalian order worldwide. In the Neotropics, Brazil has one of the greatest bat richness, but species records are still very heterogeneously distributed, especially in Amazonia. Although this biome harbours 76% of Brazil’s bat fauna, basic knowledge on the distribution of Amazonian bats is far from well known, with...

Scientists have a moral obligation to clearly warn humanity of any catastrophic threat and to “tell it like it is.” On the basis of this obligation and the graphical indicators presented below, we declare, with more than 11,000 scientist signatories from around the world, clearly and unequivocally that planet Earth is facing a climate emergency.

Bats have the second highest mammalian species richness globally, and account for about half of the mammal species diversity in tropical forests. In the Neotropical region, Brazil is the second most bat species-rich country, and the Brazilian Amazonia harbours most of the Brazilian bat diversity. However, many areas of the Amazon have sampling gaps...

The switch from hunting wild meat for home consumption to supplying more lucrative city markets in Amazonia can adversely affect some game species. Despite this, information on the amounts of wild meat eaten in Amazonian cities is still limited. We estimated wild meat consumption rates in 5 cities in the State of Amazonas in Brazil through 1046 doo...

Bats are unique among mammals, possessing some of the rarest mammalian adaptations, including true self-powered flight, laryngeal echolocation, exceptional longevity, unique immunity, contracted genomes, and vocal learning. They provide key ecosystem services, pollinating tropical plants, dispersing seeds, and controlling insect pest populations, t...

The tick fauna of Brazil is currently composed by 72 species. The state of Amazonas is the largest of Brazil, with an area of ≈ 19% of the Brazilian land. Besides its vast geographic area, only 19 tick species have been reported for Amazonas. Herein, lots containing ticks from the state of Amazonas were examined in three major tick collections from...

Twenty-five years ago, the Union of Concerned Scientists and more than 1700 independent scientists, including the majority of living Nobel laureates in the sciences, penned the 1992 “World Scientists’ Warning to Humanity” (see supplemental file S1). These concerned professionals called on humankind to curtail environmental destruction and cautioned...

The Amazon rainforest is the most biodiverse Brazilian biome regarding primate diversity, reaching 77% of the 139 taxa described for Brazil. Despite its ecological importance, Amazon biodiversity is relatively unknown. The objective of this study is to present the results of the inventory of primates at the National Forest of Tefé, Brazil, includin...

We describe morphological and morphometrical characteristics of preantral ovarian follicles from three recently recognized Saimiri species: S. macrodon, S. cassiquiarensis and S. vanzolinii; the last one a threatened species. Ovaries from four adult monkeys were evaluated: one pair from a pregnant S. macrodon, two ovarian pairs from S. cassiquiaren...

Morphological information on the reproductive system allows the understanding of ecological and behavioural aspects of different species as well as supports the development of conservational strategies. Unfortunately, for many species, not enough relevant and precise information is available. In the present study, we describe for the first time the...

Ovarian agenesis is an unusual anomaly with traumatic or congenital origin. In the present case report, we describe our findings in a senile S. vanzolinii female. As this neotropical primate species is listed as vulnerable, with limited geographic distribution in the Brazilian Amazonia, ovarian agenesis may be an important finding to be reported.

The present note reports the first record of Vampyrodes caraccioli in the Brazilian state of Amazonas, and the central Amazon region, based on 44 specimens caught in the Auati-Paraná Extractive Reserve, north bank of the Solimões/Amazonas River. Our record fills a distribution gap of this species in the Brazilian Amazon and illustrates that the cur...

This note records the first capture of Diphylla ecaudata in the state of Amazonas. This is the first record for the central Amazon, filling a gap in its distribution, as well as confirming another of Brazilian state with the presence of the species.

Cynomops planirostris is widely distributed in the Neotropical region, with records extending from Panama to northern Argentina. In Brazil, C. planirostris was recorded in 17 states, with few records in the Amazon basin. Herein we report new records of C. planirostris from the state of Amazonas.

The uniqueness of the Mamirauá Sustenainable Development Reserve (MSDR), a continuous area of floodplain and 1.124.000 ha bounded by large rivers (Solimões, Japurá and Auati-Paraná), allows only the survival of aquatic, arboreal or scansorial animals in the area throughout the seasonal cycle. Thus the profile of hunting in RDSM should be distinct f...
