Molecular Phylogenetics and Evolution, Journal Year: 2022, Volume and Issue: 178, P. 107646 - 107646

Published: Oct. 17, 2022

The Old World flycatchers, robins and chats (Aves, Muscicapidae) are a diverse songbird family with over three hundred species. Despite continuous efforts the past two decades, there is still no comprehensive well-resolved species-level phylogeny for Muscicapidae. Here we present supermatrix that includes all 50 currently recognized genera ca. 92% of species, built using data from up to 15 mitochondrial 13 nuclear loci. In addition assembling nucleotide sequences available in public databases, also extracted genome assemblies raw sequencing reads GenBank included few unpublished sequences. Our analyses resolved phylogenetic position several previously unsampled taxa, example, Grand Comoro Flycatcher Humblotia flavirostris, Collared Palm Thrush Cichladusa arquata, Taiwan Whistling-Thrush Myophonus insularis, etc. We provide taxonomic recommendations exhibit paraphyly or polyphyly. results suggest Muscicapidae diverged Turdidae (thrushes allies) early Miocene, most recent common ancestors four subfamilies (Muscicapinae, Niltavinae, Cossyphinae Saxicolinae) arose around middle Miocene.

Complete Mitochondrial Genome and Phylogenetic Analysis of Tarsiger indicus (Aves: Passeriformes: Muscicapidae)

Genes, Journal Year: 2024, Volume and Issue: 15(1), P. 90 - 90

Published: Jan. 11, 2024

Tarsiger indicus (Vieillot, 1817), the White-browed Bush Robin, is a small passerine bird widely distributed in Asian countries. Here, we successfully sequenced its mitogenome using Illumina Novaseq 6000 platform (Illumina, San Diego, CA, USA) for PE 2 × 150 bp sequencing. Combined with other published mitogenomes, conducted first comprehensive comparative analysis of Muscicapidae birds and reconstructed phylogenetic relationships between related groups. The T. was 16,723 size, it possessed typical avian structure organization. Most PCGs were initiated strictly start codon ATG, while COX1 ND2 started GTG. RSCU statistics showed that CUA, CGA, GCC relatively high frequency mitogenome. cyanurus shared very similar mitogenomic features. All 13 mitogenomes had experienced purifying selection. Specifically, ATP8 highest rate evolution (0.13296), whereas lowest (0.01373). monophylies Muscicapidae, Turdidae, Paradoxornithidae strongly supported. clade ((Muscicapidae + Turdidae) Sturnidae) Passeriformes supported by both Bayesian Inference Maximum likelihood analyses. latest taxonomic status many complex histories also For example, Monticola gularis, indicus, allocated to Turdidae literature; our topologies clearly their membership Muscicapidae; Paradoxornis heudei, Suthora webbiana, S. nipalensis, fulvifrons formerly classified into Paradoxornithidae; Culicicapa ceylonensis originally as member results are consistent position Stenostiridae.

Limited Song Mixing Without Genomic Gene Flow in a Contact Zone Between Two Songbird Species

Molecular Biology and Evolution, Journal Year: 2023, Volume and Issue: 40(3)

Published: March 1, 2023

Abstract Song is considered to play an important role in the maintenance of prezygotic reproductive isolation between closely related songbird species. Therefore, song mixing a contact zone species often as evidence hybridization. The Sichuan Leaf Warbler Phylloscopus forresti and Gansu kansuensis, which diverged 2 million years ago, have formed south Province China, where mixed songs been observed. In this study, we investigated potential causes consequences by integrating bioacoustic, morphological, mitochondrial, genomic data with field ecological observations. We found that two display no apparent morphological differences, whereas their differ dramatically. demonstrated ∼11% males sang songs. Two singing were genotyped, both be P. kansuensis. Despite presence singers, population analyses detected signs recent gene flow species, although possible cases mitochondrial introgression identified. conclude rather limited does not lead to, or result from, hybridization, hence breakdown barriers these cryptic

Hidden diversity of Aegla (Decapoda, Anomura) in a priority area for conservation

Abstract Aegla is a genus of freshwater anomuran crabs encompassing 94 described species occurring in meridional South America. Brazil harbours the greatest diversity species, mainly its southern region, which becomes priority area for conservation due to high richness and phylogenetic diversity, elevated endemism threats Atlantic Forest. Here, we assessed distribution this tested hypothesis crypticism region's species. Sampling sites were distributed inside surroundings five protected areas, covering major range several Brazil. We applied three delimitation methods COI mitochondrial gene data, coupled with morphological analyses. By integrating based on data traditional taxonomy, uncovered proportion hidden among our study identified ten known besides impressive 17 new putative Of these, eight are possible taxonomic units that do not conform any nine divided into cryptic groups: jarai complex, franciscana complex camargoi complex. Most these have narrow spatial distribution, making them highly vulnerable habitat degradation.

BASSA: New software tool reveals hidden details in visualisation of low‐frequency animal sounds

Ecology and Evolution, Journal Year: 2024, Volume and Issue: 14(7)

Published: July 1, 2024

Abstract The study of animal sounds in biology and ecology relies heavily upon time–frequency (TF) visualisation, most commonly using the short‐time Fourier transform (STFT) spectrogram. This method, however, has inherent bias towards either temporal or spectral details that can lead to misinterpretation complex sounds. An ideal TF visualisation should accurately convey structure sound terms both frequency time, STFT often cannot meet this requirement. We evaluate accuracy four methods (superlet [SLT], continuous wavelet [CWT] two STFTs) a synthetic test signal. then apply these visualise Chagos blue whale, Asian elephant, southern cassowary, eastern whipbird, mulloway fish American crocodile. show SLT visualises signal with 18.48%–28.08% less error than other methods. A comparison between our visualisations their literature descriptions indicates STFT's may have caused misinterpretations describing pygmy whale songs elephant rumbles. suggest use low‐frequency prevent such misinterpretations. Finally, we employ develop ‘BASSA’, an open‐source, GUI software application offers no‐code, user‐friendly tool for analysing short‐duration recordings Windows platform. improved accuracy, format, minimising risk while requiring technical expertise STFT.

Recent research reveals that the original series, a male and female, used to describe Ianthia johnstoniae Ogilvie-Grant, 1906 (= Collared Bush Robin Tarsiger johnstoniae), held in Natural History Museum, Tring, is mixed. The Robin, but female an example of morphologically very similar White-browed T. indicus formosanus. Because syntypes represent two different species order fix identity on universally understood taxonomic concept associated with johnstoniae, we select as its lectotype unambiguously identified specimen (NHMUK 1907.12.12.39).

Trait Variation and Spatiotemporal Dynamics across Avian Secondary Contact Zones

Biology, Journal Year: 2024, Volume and Issue: 13(8), P. 643 - 643

Published: Aug. 22, 2024

A secondary contact zone (SCZ) is an area where incipient species or divergent populations may meet, mate, and hybridize. Due to the diverse patterns of interspecific hybridization, SCZs function as field labs for illuminating on-going evolutionary processes speciation establishment reproductive isolation. Interspecific hybridization widely present in avian populations, making them ideal system SCZ studies. This review exhaustively summarizes variations unique traits within (vocalization, plumage, beak, migratory traits) various movement observed previous publications. It also highlights several potential future research directions genomic era, such relationship between phenotypic differentiation SCZs, basis trait differentiation, shared by multiple species, accurate predictive models forecasting movements under climate change human disturbances. aims provide a more comprehensive understanding offers theoretical foundation conservation.
