Abstract The identification of high‐performance indicator taxa that combine practical feasibility and ecological value requires an understanding the costs benefits surveying different taxa. We present a generic novel framework for identifying such taxa, illustrate our approach using large‐scale assessment 14 higher across three forest types in Brazilian Amazon, estimating both standardized survey cost biodiversity each taxon. Survey varied by orders magnitude, dung beetles birds were...
Titi monkeys, Callicebus, comprise the most species-rich primate genus-34 species are currently recognised, five of them described since 2005. The lack molecular data for titi monkeys has meant that little is known their phylogenetic relationships and divergence times. To clarify evolutionary history, we assembled a large dataset by sequencing 20 nuclear two mitochondrial loci 15 species, including representatives from all recognised groups. Phylogenetic were inferred using concatenated...
The rich diversity of morphology and behavior displayed across primate species provides an informative context in which to study the impact genomic on fundamental biological processes. Analysis that insight into long-standing questions evolutionary conservation biology is urgent given severe threats these are facing. Here, we present high-coverage whole-genome data from 233 representing 86% genera all 16 families. This dataset was used, together with fossil calibration, create a nuclear DNA...
Personalized genome sequencing has revealed millions of genetic differences between individuals, but our understanding their clinical relevance remains largely incomplete. To systematically decipher the effects human variants, we obtained whole-genome data for 809 individuals from 233 primate species and identified 4.3 million common protein-altering variants with orthologs in humans. We show that these can be inferred to have nondeleterious humans based on presence at high allele...
Rivers have been suggested to played an important role in shaping present-day patterns of ecological and genetic variation among Amazonian species communities. Recent molecular studies provided mixed support for the hypothesis that large lowland rivers functioned as significant impediments gene flow populations neotropical species. To date, no study has systematically evaluated impact riverine barriers might on structuring whole Our analyses phylogeography frogs small mammals indicate a...
Abstract Noncoding DNA is central to our understanding of human gene regulation and complex diseases 1,2 , measuring the evolutionary sequence constraint can establish functional relevance putative regulatory elements in genome 3–9 . Identifying genomic that have become constrained specifically primates has been hampered by faster evolution noncoding compared protein-coding 10 relatively short timescales separating primate species 11 previously limited availability whole-genome sequences 12...
Species of Neacomys are small cricetid rodents that occur in forested habitats Central and South America, from eastern Panama to central Bolivia central/western Brazil. In order assess species diversity this poorly known genus, we obtained cytochrome b gene sequences the most comprehensive taxonomic geographic sampling analyzed date. We also conducted morphological analyses on a large series specimens housed 15 museums, including types 10 out 14 nominal taxa. Our genetic data recovered 17...
Abstract The application of environmental DNA (eDNA) metabarcoding as a biomonitoring tool has greatly increased, but studies have focused on temperate aquatic macro‐organisms. We apply eDNA to detecting the mammalian community in two high‐biodiversity regions Brazil: Amazon and Atlantic Forests. identified Critically Endangered species found overlap with via camera trapping. highlight potential for using monitoring mammals biodiverse identify challenges: we need better understanding ecology...
Mitochondrial DNA remains a cornerstone for molecular ecology, especially study species from which high-quality tissue samples cannot be easily obtained. Methods using mitochondrial markers are usually reliant on reference databases, but these often incomplete. Furthermore, available genomes lack crucial metadata, such as sampling location, limiting their utility many analyses. Here, we assembled 205 new platyrrhine primates, most the Amazon and with known locations. We present dated...
Abstract Background Most populations of spider monkeys ( Ateles ) and muriquis Brachyteles ), two Neotropical primate genera, are under severe anthropogenic threats. Yet, taxon-wide population-level studies leveraging their degree endangerment linked to genetic diversity patterns demographic history lacking. To properly address this, there is a need expand from morphological marker-based studies. Results We generated high-coverage genome sequencing for 58 individuals sampled across 8...
Until the recent construction of hydroelectric dams, a series 18 rapids divided upper and lower Madeira River, these were thought to separate two species Amazonian freshwater dolphins (boto): Inia boliviensis (above) I. geoffrensis (below). Some reports articles, however, mention occurrence botos within region that they occasionally cross rapids, but without mentioning concerned. Based on our previous studies, it is likely occurs in rapids. To test this supposition, we sampled individuals...
The taxonomy of the titi monkeys (Callicebinae) has recently received considerable attention. It is now recognised that this subfamily composed three genera with 33 species, seven them described since 2002. Here, we describe a new species titi, Plecturocebus, from municipality Alta Floresta, Mato Grosso, Brazil. We adopt an integrative taxonomic approach includes phylogenomic analyses, pelage characters, and locality records. A reduced representation genome-wide was employed to assess...

The marsupials of the family Didelphidae went through profound taxonomic rearrangements in recent decades, mainly related to an increase number specimens deposited scientific collections and inclusion molecular data systematic analyses, resulting better resolved phylogenies taxa delimitation. Analyses a large series gracile mouse opossum Gracilinanus agilis, including types complementary material, recovered assignable Marmosa agilis peruana Tate, 1931 as monophyletic group that is...
Although the Atlantic Forest marmosets (Callithrix spp.) are among best studied Neotropical primates, Amazonian (Callibella humilis, Cebuella spp. and Mico much less well-known. Even species diversity distributions yet to be properly determined because field data materials currently available in scientific collections do not allow comprehensive taxonomic studies of marmosets. From 2015 2018, we conducted 10 expeditions key-areas within southern Amazonia where little or no information on was...
We present new karyotype records for six Proechimys species from the Brazilian Amazon. P. echinothrix region of Purus River had 2n = 32 chromosomes and a FN 58, while cuvieri Japurá presented 28 46. All individuals hybridization with an 18S rDNA probe in single chromosome pair, exception region, which third signal one homologs pair 1. No ITS were found any individuals. Our data supports hypothesis that population Basin lower are taxonomic entities. expand geographic distribution cytotype (2n...
Although the Amazon has greatest diversity of primates, there are still taxonomic uncertainties for many taxa, such as species Saguinus mystax group. The most geographically broadly distributed and phenotypically diverse in this group is S . , its phenotypic been recognized three subspecies— pileatus pluto —with non-overlapping geographic distributions. In sense, we carried out an extensive field survey their distribution areas used a framework hypothesis testing genomic data combined with...
Abstract Motivation SIA‐BRA is a data set that compiles stable carbon (C) and nitrogen (N) isotope ratios of terrestrial aquatic animals sampled in Brazilian biomes coastal marine areas. Stable are helpful animal ecology for several reasons; instance, they can be used to investigate trophic niches, energy sources (diet tracing) track migration patterns. The Neotropics considered one the most undersampled regions world. Given Brazil continental country where dietary species under‐assessed, we...
