The Amazon is the primary source of Neotropical diversity and a nexus for discussions on processes that drive biotic diversification. Biogeographers have focused roles rivers Pleistocene climate change in explaining high rates speciation. We combine phylogeographic niche-based paleodistributional projections 23 upland terra firme forest bird lineages from across to derive new model regional biological found climate-driven refugial dynamics interact with dynamic riverine barriers produce...
Abstract Geographic barriers are frequently invoked to explain genetic structuring across the landscape. However, inferences on spatial and temporal origins of population variation have been largely limited evolutionary neutral models, ignoring potential role natural selection intrinsic genomic processes known as architecture in producing heterogeneity differentiation genome. To test how characteristics (e.g. recombination rate) impacts our ability reconstruct general patterns between...
To elucidate the relationships and spatial range evolution across world of bird genus Turdus (Aves), we produced a large genomic dataset comprising ca 2 million nucleotides for 100 samples representing 53 species, including over 2000 loci. We estimated time-calibrated maximum-likelihood multispecies coalescent phylogenies carried out biogeographic analyses. Our results indicate that there have been considerably fewer trans-oceanic dispersals within than previously suggested, such Palaearctic...
The rich biodiversity of Amazonia is shaped geographically and ecologically by its rivers their cycles seasonal flooding. Anthropogenic effects, such as deforestation, infrastructure development extreme climatic events, threaten the ecological processes sustaining Amazonian ecosystems. In this Review, we explore coupled evolution associated with terrestrial seasonally flooded environments, integrating geological, climatic, genetic evidence. fluvial environments are highly heterogeneous,...
The physiological responses of juvenile tambaqui (Colossoma macropomum) fed commercial feed supplemented with different concentrations camu (Myrciaria dubia) were evaluated. design was completely randomized, treatments arranged in a factorial three proportions (15%, 30% and 45%) control treatment (100% diet), four replicates per treatment. A total 96 specimens used, mean initial weight 11.69 ± 2.68 g length 7.06 0.44 cm. After 30 days, hematological parameters, metabolic variables, growth...
The eastern Andean slopes harbours a diverse fauna with multiple endemic and endangered species. region is identified as biodiversity hotspot high conservation priority. However, it remains one of the least studied in South America regarding diversity mammals. Here we present new data on non-volant small mammals (marsupials rodents) from Parque Nacional del Río Abiseo (PNRA), poorly known, remote site located central-northern Peru. We sequenced mitochondrial gene cytochrome b to provide...
Target sequence capture has emerged as a powerful method to hundreds or thousands of genomic regions in cost- and time-efficient approach. In most cases, however, targeted lack full information for certain samples, due taxonomic, laboratory, stochastic factors. Loci lacking molecular data large number samples are commonly excluded from downstream analyses, even though they may still contain valuable information. On the other hand, including data-poor loci bias phylogenetic analyses. Here we...
Abstract Dental topographic metrics (DTMs), which quantify different aspects of the shape teeth, are powerful tools for studying dietary adaptation and evolution in mammals. Current DTM protocols usually rely on proprietary software, may be unavailable to researchers reasons cost. We address this issue context a analysis primate clade Platyrrhini (“New World monkeys”) by: 1) presenting large comparative sample scanned second lower molars (m2s) callitrichids (marmosets tamarins), previously...
Abstract Aim The central and western Amazonia underwent several landscape changes during the Quaternary. Whereas Riverine Barrier Hypothesis is traditionally used to explain influence of rivers on speciation, processes such as river rearrangements have been overlooked geographic distribution evolutionary history biota. Here, we tested how influenced uakari monkeys, genus Cacajao , a primate primarily associated with seasonally flooded forests in Amazonia. Location Central Western Taxon...
Abstract The genus Willisornis is endemic to the Amazon Basin, inhabiting upland terra firme forest, with two species and seven subspecies currently recognized. Despite numerous systematic studies, a taxonomically-dense sampled phylogeny for still lacking, which, combined evidence of paraphyly gene flow between its recognized species, underscores uncertainty concerning limits evolutionary history genus. Here we present phylogenies population genetic analyses, including all taxa, relating...
The true diversity and interspecific limits in the Neotropical endemic avian genus Dendrocolaptes (Furnariidae) remain a highly controversial subject, with previous genus-wide assessments, based mostly on morphological characters, producing poorly resolved phylogenies. lack of well-resolved, robust, taxonomically densely sampled phylogenies for prevents reliable inferences genus' actual species evolutionary history. Here, we analyzed 2,741 base pairs mitochondrial nuclear genes from 43...

Instead annotating whole genomes, many phylogenetic studies focus efforts on sets pre-selected loci, which further reduces costs bioinformatic challenges while increasing depth. One common approach that enriches loci before is often referred to as target sequence capture. This technique has been shown be applicable greatly varying evolutionary depth proven produce powerful, multi-locus...

ABSTRACT Aim Western Amazonia is a region that underwent several landscape changes during the Quaternary. While Riverine Barrier Hypothesis traditionally used to explain influence of rivers on speciation, processes such as river rearrangements have been overlooked geographic distribution and evolutionary history biota.

Areas of endemism are the smallest units in biogeography and can be defined as biologically unique areas comprising taxa with common geographic limits to their distributions. High beta diversity within Amazonia is often related turnover among these areas. For decades, evolutionary biologists have tried comprehend mechanisms generating maintaining spatial structure high free-living Amazonian organisms, particularly birds. However, few studies analyze patterns parasites. Host parasite...
Abstract The Asian and Australo‐Papuan faunas meet intermix across the islands of Wallacea. Untangling origins relationships species inhabiting these archipelagos is an ongoing project that has lasted for well over a century. In recent years, molecular phylogenetic studies have made considerable progress in clarifying affinities enigmatic Wallacean taxa, but taxonomic riddles remain, even groups as studied birds. Such case with Sulawesi Thrush Cataponera turdoides , scarce elusive montane...
Abstract Large rivers are ubiquitously invoked to explain the distributional limits and speciation of Amazon Basin’s mega-diversity. However, inferences on spatial temporal origins Amazonian species have narrowly focused evolutionary neutral models, ignoring potential role natural selection intrinsic genomic processes known produce heterogeneity in differentiation across genome. To test how architecture impacts our ability reconstruct patterns diversification multiple taxa, we sequenced...
The use of Ultraconserved Elements (UCEs) as genetic markers in phylogenomics has become popular and provided promising results. Although UCE data can be easily obtained from targeted enriched sequencing, the protocol for silico analysis UCEs consist execution heterogeneous complex tools, a challenge scientists without training bioinformatics. Developing tools with adoption best practices research software lessen this problem by improving computational experiments, thus promoting better...
Abstract Dental topographic metrics (DTMs), which quantify different aspects of the shape teeth, are powerful tools for studying dietary adaptation and evolution in mammals. However, comparative samples scanned mammal teeth suitable analysis with DTMs remain limited size scope, little or no representation some major lineages, even within well-studied clades such as primates. In addition, current DTM protocols usually rely on proprietary software, may be unavailable to many researchers...
