Abstract

We describe a new taxon of manakin in the Machaeropterus regulus complex, from the foothills of southwestern Loreto and northern San Martín departments, Peru. This new form appears to be almost identical morphologically to the Tepui form M. regulus aureopectus but differs strongly from that and all other members of the M. regulus complex in voice. Therefore, we conclude that this population represents a new biological species that we here name Machaeropterus eckelberryi. Based on voice and some morphological characters, we concur with several previous authors (e.g., Whittaker & Oren 1999; Snow 2004; Ridgely & Tudor 2009) that nominate M. regulus (Eastern Striped Manakin), of the Atlantic Forest of Brazil, should be separated as a biological species from the polytypic Machaeropterus striolatus of western South America (Western Striped Manakin), including M. s. striolatus of Amazonia, M. r. obscurostriatus and M. r. zulianus of the Venezuelan Andes, M. r. antioquiae of the Colombian Andes, and M. r. aureopectus of the tepuis region.

Lepidothrix vilasboasi

Barrera-Guzmán, Alexandre, Shawkey, Weir. 2017. Hybrid speciation leads to novel male secondary sexual ornamentation of an Amazonian bird. Proc. Natl. Acad. Sci. USA (early edition).
[abstract & supp.inf.]

Hybrid speciation is rare in vertebrates, and reproductive isolation arising from hybridization is infrequently demonstrated. Here, we present evidence supporting a hybrid-speciation event involving the genetic admixture of the snow-capped (Lepidothrix nattereri) and opal-crowned (Lepidothrix iris) manakins of the Amazon basin, leading to the formation of the hybrid species, the golden-crowned manakin (Lepidothrix vilasboasi). We used a genome-wide SNP dataset together with analysis of admixture, population structure, and coalescent modeling to demonstrate that the golden-crowned manakin is genetically an admixture of these species and does not represent a hybrid zone but instead formed through ancient genetic admixture. We used spectrophotometry to quantify the coloration of the species-specific male crown patches. Crown patches are highly reflective white (snow-capped manakin) or iridescent whitish-blue to pink (opal-crowned manakin) in parental species but are a much less reflective yellow in the hybrid species. The brilliant coloration of the parental species results from nanostructural organization of the keratin matrix feather barbs of the crown. However, using electron microscopy, we demonstrate that the structural organization of this matrix is different in the two parental species and that the hybrid species is intermediate. The intermediate nature of the crown barbs, resulting from past admixture appears to have rendered a duller structural coloration. To compensate for reduced brightness, selection apparently resulted in extensive thickening of the carotenoid-laden barb cortex, producing the yellow crown coloration. The evolution of this unique crown-color signal likely culminated in premating isolation of the hybrid species from both parental species.

Lepidothrix

Cleyssian Dias, Keila de Araújo Lima, Juliana Araripe, Alexandre Aleixo, Marcelo Vallinoto, Iracilda Sampaio, Horacio Schneider, Péricles Sena do Rêgo. Mitochondrial introgression obscures phylogenetic relationships among Manakins of the genus Lepidothrix (Aves: Pipridae). Molecular Phylogenetics and Evolution, Available online 12 April 2018.

Abstract:

Lepidothrix is the most diverse genus of the family Pipridae, with eight recognized species. Although the genus' monophyly has been supported by both molecular and morphological characters, phylogenetic relationships and species limits within Lepidothrix remain uncertain. In the present study, we combined molecular sequences of mitochondrial (ND2 and COI) and nuclear (MYO, G3PDh and I5BF) markers in a multilocus analysis, to evaluate relationships and inter-specific limits among L. iris, L. nattereri, and L. vilasboasi, which are known to hybridize in eastern Amazonia. The results revealed a complex pattern, whereby events of secondary contact and gene flow after isolation and genetic and phenotypic differentiation prevented the recuperation of reciprocal monophyly among the studied taxa. The mitochondrial data indicate that L. nattereri is divided into two non-sister groups, one monophyletic, and the other, paraphyletic, with L. iris iris being more closely related to one of the two L. nattereri groups, while L. iris eucephala forms an undifferentiated clade with L. vilasboasi, probably resulting from an extensive process of mitochondrial introgression. In agreement with a previous study based on Single Nucleotide Polymorphism (SNP) data, mitochondrial haplotype networks also support that L. vilasboasi does not represent a recent “hybrid swarm” between L. iris and L. nattereri, but instead a genetically divergent lineage with a separate species status. Finally, the sister relationship recovered herein between L. iris iris and some western populations of L. nattereri currently in allopatry is also apparently explained by mitochondrial introgression, as also supported for nuclear genes by SNP data, indicating a complex scenario of past contact and gene flow between currently geographically distant Lepidothrix lineages.

João Marcos Guimarães Capurucho, Mary V. Ashley, Camila C. Ribas, John M. Bates. Connecting Amazonian, Cerrado, and Atlantic Forest histories: Paraphyly, old divergences, and modern population dynamics in tyrant-manakins (Neopelma/Tyranneutes, Aves: Pipridae).
Molecular Phylogenetics and Evolution. In Press, Accepted Manuscript, Available online 12 June 2018

Abstract :

Within lineage structure and recent demographic fluctuations are observed.
Abstract
Several biogeographic hypotheses have been proposed to explain connections between Amazonian and Atlantic forest biotas. These hypotheses are related to the timing of the connections and their geographic patterns. We performed a phylogeographic investigation of Tyrant-manakins (Aves: Pipridae, Neopelma/Tyranneutes) which include species inhabiting the Amazon and Atlantic forests, as well as gallery forests of the Cerrado. Using DNA sequence data, we determined phylogenetic relationships, temporal and geographic patterns of diversification, and recent intraspecific population genetic patterns, relative to the history of these biomes. We found Neopelma to be a paraphyletic genus, as N. chrysolophum is sister to Neopelma + Tyranneutes, with an estimated divergence of approximately 18 Myrs BP, within the oldest estimated divergence times of other Amazonian and Atlantic forest avian taxa. Subsequent divergences in the group occurred from Mid Miocene to Early Pliocene and involved mainly the Amazonian species, with an expansion into and subsequent speciation in the Cerrado gallery forests by N. pallescens. We found additional structure within N. chrysocephalum and N. sulphureiventer. Analysis of recent population dynamics in N. chrysocephalum, N. sulphureiventer, and N. pallescens revealed recent demographic fluctuations and restrictions to gene flow related to environmental changes since the last glacial cycle. No genetic structure was detected across the Amazon River in N. pallescens. The tyrant-manakins represent an old historical connection between the Amazon and Atlantic Forest.

Sofia Marques Silva, Carlos Eduardo Agne, Alexandre Aleixo, Sandro L. Bonatto. Phylogeny and systematics of Chiroxiphia and Antilophia manakins (Aves, Pipridae)
Molecular Phylogenetics and Evolution. In Press, Accepted Manuscript, Available online 12 June 2018

Abstract

Chiroxiphia and Antilophia manakins are recognized as closely related genera. Nonetheless, Chiroxiphia has been recovered as paraphyletic in some studies with limited taxonomic coverage. This genus currently comprises five species, although this arrangement is still unsettled. Chiroxiphia pareola is the most widespread species, with four recognized subspecies, but their taxonomic status are also uncertain. Finally, the phylogenetic relationships amongst the majority of Chiroxiphia and Antilophia taxa are unknown. Here, we use multilocus DNA sequences from multiple individuals of all currently accepted species and subspecies of both genera to infer their phylogenetic relationships and its implications on their classification. Our results suggest Chiroxiphia, as currently defined, is a paraphyletic group, since C. boliviana is more closely related to Antilophia than to the remaining Chiroxiphia taxa. Within C. pareola, our results support that C. p. regina and C. p. napensis should be treated as independent species. We found three divergent clades in C. p. pareola likely corresponding to distinct subspecies: one in which the isolated and endemic Tobago Island C. p. atlantica individuals are grouped with C. p. pareola from the north bank of the lower Amazon River; and two sister clades comprising individuals distributed south of the Amazon river, and those from the Atlantic Forest.

Antilophia

Luna LW, Girão e Silva WA, Araripe J, Pereira ITF, d’Horta FM, Sampaio I, Schneider H, do Rêgo PS. 2018. Mutations in the melanocortin-1 receptor (MC1R) gene have no influence on the distinct patterns of melanic plumage found in the manakins of the genus Antilophia (Aves: Pipridae). An. Acad. Bras. Ciênc., 90: 2873-2879.
[full paper]

ABSTRACT
The melanocortin-1 receptor gene is the most widely-used marker for the investigation of the genetic determination of melanic plumage patterns. Studies of a number of wild bird species have shown an association between non-synonymous mutations of the MC1R gene and the presence of melanic variants. The genus Antilophia (Pipridae) includes only two manakin species (A. galeata and A. bokermanni), which are distinguished primarily by the differences in the pattern of melanic coloration of the plumage of the mantle in the adult males. In A. galeata, this plumage is black, while in A. bokermanni, it is predominantly white. This study investigates the possible association between mutations of the MC1R marker and the variation in plumage coloration observed in the two species. The MC1R sequences of the two species was analyzed, and the observed nucleotide variation was compared. Six polymorphic sites were identified, representing seven distinct genotypes. Five of these polymorphic mutations were non-synonymous, but were not related to the different phenotypes. Neutral evolution and the absence of any systematic association between the variants of the MC1R and plumage coloration in the Antilophia species indicate that alternative mechanisms regulate the expression of the coloration of the plumage in the adult males.
Key words: candidate gene, manakin, melanism, neutral evolution, plumage color.

Antilophia spp

Souza, T.O., Luna, L.W., Araripe, J. et al. Characterization of the genetic diversity and population structure of the manakin genus Antilophia through the development and analysis of microsatellite markers. J Ornithol (2019). https://doi.org/10.1007/s10336-019-01655-w

Abstract:

The two species of the genus Antilophia, Antilophia bokermanni and Antilophia galeata, are found in environments that are undergoing extensive modification, which may be provoking the loss of their genetic diversity. Nine polymorphic microsatellite loci were characterized and analyzed in each of these species. The distribution of allele frequencies revealed two clusters that reflected the distinct genetic profile of each species. Observed levels of heterozygosity were low for each species, with the lowest allelic diversity found in the critically endangered A. bokermanni. The set of loci described here, in contrast with other genetic markers that have been analyzed previously, effectively diagnosed the genetic diversity of different populations of the two species.

BirdLife's Globally Threatened Bird Forums

The newly described taxon Painted Manakin (Machaeropterus eckelberryi) is to be recognized as a species by BirdLife International.

Posted on May 23, 2019 by Red List Team (BirdLife International)

Painted Manakin (Machaeropterus eckelberryi) was discovered in 1996 in the Cordillera Azul of the Peruvian Andes. Based on its vocalisation and on genetic and morphological analysis, the species was described as a new taxon in 2017 (Lane et al. 2017).

Based on current information, Painted Manakin seems to be restricted to a small area in the foothills of the Andes in the departments of San Martín and Loreto in northern Peru, including the Cordillera Azul National Park (Lane et al. 2017). It is assumed that its range spans the ridges of the eastern flanks of the Cordillera Azul, Cordillera Escalera and the Mayo Valley at altitudes between c. 550 and 1,600 m (Lane et al. 2017). The population size has not been estimated.

Painted Manakin inhabits woodlands of up to 20 m canopy height on poor, sandy soils (Lane et al. 2017). It is frequently found near Melastomaceae trees, where it feeds on berries in the mid-story and canopy layer (Lane et al. 2017).

To date, there are no known threats to the species. Its preferred poor-soil woodland habitat is not suitable for agriculture and therefore not subject to the heavy logging that is currently ongoing, particularly in the Cordillera Azul (Lane et al. 2017, Moncrieff et al. 2018). Moreover, large parts of the range are protected in the Cordillera Azul National Park. Overall, Painted Manakin seems to be under much lower threat than other endemic species of the north-central Peruvian Andes, including the recently discovered Cordillera Azul Antbird (Myrmoderus eowilsoni) (Lane et al. 2017, Moncrieff et al. 2018).

Lepidothrix coronata

Camila Alves Reis, Cleyssian Dias, Juliana Araripe, Alexandre Aleixo, Marina Anciães, Iracilda Sampaio, Horacio Schneider, Péricles Sena do Rêgo. Multilocus data of a manakin species reveal cryptic diversification moulded by vicariance. Zoologica Scripta, First published: 15 November 2019|
https://doi.org/10.1111/zsc.12395

Abstract:

We used molecular tools and a multilocus approach to investigate the phylogeography of Lepidothrix coronata across most of its ample range. We sequenced six DNA fragments to produce phylogenies, molecular dating estimates, analyses of the dynamics of the demographic history of the species and a biogeographic analysis to estimate the events and changes in the ancestral distribution of the species. The results indicated the presence of four well‐established lineages, with high levels of divergence. These lineages are delineated by well‐defined geographic barriers, with one lineage, restricted to the west of the Andes, being the first to diverge from the complex. The other three lineages are exclusive to the Amazonian distribution of the species, with two being found north of the Amazon River, and the third, south of the Amazon. Some of the relationships found between these lineages were distinct from those described in previous studies. Important disagreements were found between the mtDNA phylogeny and that of the multilocus analysis, in relation to the lineages located to the west of the Andes. We propose that past introgression events may have influenced shifts in the relationships between lineages, despite the fact that the groups were well defined in both the phylogenies. The biogeographic analysis indicates that the lineages arose through successive vicariance events, which had a primary role in the diversification of the group. Two or three genetically structured subclades were also found within each Amazonian lineage, although these subclades are not isolated by an obvious geographic barrier.

Pipra fasciicauda x Pipra aureola

Sampaio, L., Ferraz, D.O., da Costa, A.C.M. et al. Analyses of plumage coloration and genetic variation confirm the hybridization of Pipra fasciicauda and Pipra aureola in the Brazilian Amazon basin. J Ornithol (2020) doi:10.1007/s10336-020-01744-1

Abstract:

The present study aimed to confirm the occurrence of a hybridization event between the band-tailed manakin (Pipra fasciicauda) and the crimson-hooded manakin (Pipra aureola), based on the existence of a specimen that presents morphological traits of both taxa. We analyzed 297 taxidermized skins of adult males of the two species, including the potential hybrid. We also analyzed the mitochondrial (ND2, ND3 e COI) and nuclear (FGB-I5, MB-I2 e GAPDH-I3) genes of 12 adult specimens of the two taxa, diagnosed phenotypically, in addition to the potential hybrid. The analyses of the plumage indicated that the potential hybrid has an intermediate pattern of white banding on the tail that is less extensive than that found in Pipra fasciicauda, but that its other phenotypic traits are characteristic of Pipra aureola. The molecular topologies revealed two clades, one that groups P. aureola together with the potential hybrid, and the other that corresponds to P. fasciicauda. These findings allowed us to confirm the occurrence of a process of hybridization and potential introgression through secondary events in the P. aureola lineage.

Pseudopipra pipra

Jacob S. Berv, Leonardo Campagna, Teresa J. Feo, Ivandy Castro-Astor, Camila C. Ribas, Richard O. Prum, Irby J. Lovette. Genomic phylogeography of the White Crowned Manakin Pseudopipra pipra (Aves: Pipridae) illuminates a continental-scale radiation out of the Andes. bioRxiv, Posted July 24, 2019.
doi: https://doi.org/10.1101/713081

Abstract:

The complex landscape history of the Neotropics has generated opportunities for population isolation and subsequent diversification that place this region among the most species-rich in the world. Detailed phylogeographic studies are required to uncover the biogeographic histories of Neotropical taxa, to identify evolutionary correlates of diversity, and to reveal patterns of genetic connectivity, disjunction, and potential differentiation among lineages from different areas of endemism. The White-crowned Manakin (Pseudopipra pipra) is a small suboscine passerine bird that is broadly distributed through the subtropical rainforests of Central America, the lower montane cloud forests of the Andes from Colombia to central Peru, the lowlands of Amazonia and the Guianas, and the Atlantic forest of southeast Brazil. Pseudopipra is currently recognized as a single, polytypic biological species. We studied the effect of the historical and current Neotropical landscape on genetic and phenotypic differentiation within this species using genomic data derived from double digest restriction site associated DNA sequencing (ddRAD), and mitochondrial DNA. Our analyses identify five ancient clades, which encompass seventeen well-differentiated populations. Most of the breakpoints among populations coincide with physical barriers to gene flow previously associated with avian areas of endemism, and generally coincide with subspecies boundaries. The phylogenetic relationships among these populations imply a unique pattern of a montane Andean origin for the genus, with a subsequent expansion and radiation into the Amazonian lowlands. Analyses of genomic admixture demonstrate a complex history of introgression between some western Amazonian populations, which confound standard concatenated and coalescent phylogenetic analyses, and raise the possibility that a lineage in the western Napo area of endemism is of hybrid origin. Lastly, we analyze variation in vocal phenotypes in the context of our phylogeny and propose that Pseudopipra is a species-complex composed of 15-17 distinct species which have arisen in the last ∼2.5 Ma.

Yowser- need a detailed read through but bold proposal. Looks like they propose a minimum 8-way split!

Don't get too excited, Josh. This is the unreviewed manuscript (why on Earth would that be made public?!). It is fraught with many problems, not least of which was a very poor understanding of the taxonomy and biogeography of the complex, and was rejected by the journal. Haven't heard anything more about a re-submission anywhere.

Why wouldn't it be made public? Nothing too controversial about placing manuscripts on BioRxiv.

I don't know... If your manuscript is greatly flawed with simple issues, do you want the general public to see that? If it is rejected, or if the submission-to-publication time is particularly long with some journal, what is to stop some unscrupulous second party from simply lifting your idea or results and publishing them themselves? I can think of various reasons. It seems like waiting until the reviewed paper is accepted would be the time to release it publicly, if not *on the actual publication date*.

It's all a trade off. Sure, there may be issues with preprint manuscripts, that's totally normal. However there are many benefits. It allows for friendly review to improve the quality of the manuscript. They are given a DOI number and are citable, therefore preventing anyone 3rd parties from publishing the data under their own name. Finally, it is particularly useful for junior scientists such as masters students and PhD students who don't have the luxury of waiting months for the review process to add and demonstrate the presence of submission-ready manuscripts to CVs and for grant applications.
