Finding new species Thousands of have been described, and, although most may agree that many thousand remain undiscovered, identifying taxa charismatic vertebrates, like birds, is rare. Rheindt et al. describe five songbird and subspecies found on a single small island near Sulawesi, Indonesia, over 6-week expedition (see the Perspective by Kennedy Fjeldså). They targeted area because its geological history complexity historical notes other explorers. argue similar approaches in regions could also lead to discovery species.

Extensive paraphyly in the typical owl family (Strigidae)

Ornithology, Год журнала: 2019, Номер 137(1)

Опубликована: Дек. 12, 2019

Abstract The typical owl family (Strigidae) comprises 194 species in 28 genera, 14 of which are monotypic. Relationships within and among genera the owls have been challenging to discern because mitochondrial data produced equivocal results many monotypic omitted from previous molecular analyses. Here, we collected analyzed DNA sequences ultraconserved elements (UCEs) 43 produce concatenated multispecies coalescent-based phylogenetic hypotheses for all but one genus family. Our reveal extensive paraphyly taxonomic groups across phylogenies inferred using different analytical approaches suggest Athene, Otus, Asio, Megascops, Bubo, Strix paraphyletic, whereas Ninox Glaucidium polyphyletic. Secondary analyses protein-coding genes harvested off-target sequencing reads genomes downloaded GenBank generally support extent observe, although some disagreements exist at higher levels between our nuclear hypotheses. Overall, demonstrate importance taxon sampling understanding describing evolutionary relationships this group, as well need additional sampling, study, revision species. Additionally, findings highlight how both divergence convergence morphological characters obscured history owls, particularly those with insular distributions.

Tramps in transition: genetic differentiation between populations of an iconic "supertramp" taxon in the Central Indo-Pacific

Frontiers of Biogeography, Год журнала: 2022, Номер 14(2)

The island monarch (Monarcha cinerascens) was an original example of the “supertramp strategy”. This involves well-developed dispersal specialisation, enabling a species to colonise remote islands but leaving it competitively inferior. Supertramps are hypothesised be excluded from larger by superior competitors. It is only Melanesian supertramp occur in Wallacea, home also sedentary pale-blue (Hypothymis puella). We interrogate strategy and its biogeographical underpinnings assessing population structure these two monarchs. sampled monarchs collecting DNA morphological data. investigated applying ABGD Bayesian Maximum Likelihood methods their ND2 ND3 genes. constructed linear models investigate relationships between genetic divergence, ability, area, elevation, isolation. Wallacea’s deep waters restrict gene flow even supertramp, as Wallacean likely separate (mean distance: 2.7%). mirrors split Asia’s black-naped azurea). found further within populations. Their divergence related isolation islands, well ability birds. However, independent elevation area. Rather than being r-selected on small, disturbance-prone our results support view that monarch’s lifestyle temporary stage taxon cycle, i.e. supertramps may transition into resident after colonisation. Our suggest more dispersive reach distant promoted or permanent, without selection against per se. helps determine distribution across not necessarily occurring thereafter.

DNA barcoding a unique avifauna: an important tool for evolution, systematics and conservation

BMC Evolutionary Biology, Год журнала: 2019, Номер 19(1)

DNA barcoding utilises a standardised region of the cytochrome c oxidase I (COI) gene to identify specimens species level. It has proven be an effective tool for identification avian samples. The unique island avifauna New Zealand is taxonomically and evolutionarily distinct. We analysed COI sequence data in order determine if could accurately birds.We sequenced 928 from 180 species. Additional Genbank sequences expanded dataset 1416 211 estimated 236 Furthermore, improve assessment genetic variation non-endemic species, assess overall accuracy our approach, 404 collected outside were also included analyses. Of 191 represented by multiple sequences, 88.5% successfully identified their barcodes. This likely conservative estimate power Zealand, given extensive geographic sampling. majority 13 groups that not distinguished contain recently diverged taxa, indicating incomplete lineage sorting some cases hybridisation. In contrast, 16 showed evidence distinct intra-species lineages, these corresponding recognised subspecies. For purposes character-based method was more successful than distance phylogenetic tree-based methods.DNA barcodes most bird However, low levels divergence taxa limit barcoding. A small number currently would benefit further systematic investigations. reference database analysis presented will provide valuable insights into evolution, systematics conservation birds.

Cryptic diversity in Cyornis (Aves: Muscicapidae) jungle-flycatchers flagged by simple bioacoustic approaches

Zoological Journal of the Linnean Society, Год журнала: 2019, Номер 186(3), С. 725 - 741

Опубликована: Янв. 31, 2019

Despite the ongoing taxonomic revolution incorporating multiple species delimitation methods, knowledge gaps persist in taxonomy of comparatively well-studied animal groups such as birds. Morphologically cryptic risk slipping under conservation radar, they get mistakenly united with other species. Here, we employed six to 11 vocal parameters each population examine nine Cyornis jungle-flycatcher complexes distributed across Asia. We found moderate strong evidence for elevation ten Additionally, conducted mitochondrial and genome-wide SNP analyses two effectiveness bioacoustics a tool avian delineation congruent results between molecular data. Therefore, propose reclassification complicated recommend routine application classification.

Species limits in Syma kingfishers using plumage, morphometric and bioacoustic analyses

Zootaxa, Год журнала: 2025, Номер 5604(2), С. 156 - 166

Опубликована: Март 12, 2025

The genus Syma Lesson, 1827 is unanimously considered to comprise two very similar, altitudinally-segregated species in the New Guinea bioregion: Yellow-billed Kingfisher S. torotoro and Mountain megarhyncha. One taxon, t. ochracea of D’Entrecasteaux Archipelago off eastern Guinea, has recently been suggested as an independent species, but evidence so far remained unassembled. Here, I combine morphometric plumage data 127 museum specimens (including 34 ochracea), bioacoustic from 52 sound recordings analyse limits this complex. Morphologically, differs distinctly both megarhyncha underpart colouration mensurally—but not geographically—intermediate between them (but with more overlap rather than its current conspecific). Vocally, long short songs are highly divergent other populations. This body suggests that merits rank, for which suggest English name ‘Ochre-bellied Kingfisher’. IUCN Red List status newly split determined be Near Threatened.

Phylogenomics of white-eyes, a ‘great speciator’, reveals Indonesian archipelago as the center of lineage diversity

eLife, Год журнала: 2020, Номер 9

Опубликована: Дек. 22, 2020

Archipelagoes serve as important 'natural laboratories' which facilitate the study of island radiations and contribute to understanding evolutionary processes. The white-eye genus Zosterops is a classical example 'great speciator', comprising c. 100 species from across Old World, most them insular. We achieved an extensive geographic DNA sampling by using historical specimens recently collected samples. Using over 700 genome-wide loci in conjunction with coalescent tree methods gene flow detection approaches, we untangled reticulated history Zosterops, comprises three main clades centered Indo-Africa, Asia, Australasia, respectively. Genetic introgression between permeates phylogeny, regardless how distantly related are. Crucially, identified Indonesian archipelago, specifically Borneo, major center diversity only area where all overlap, attesting importance this region.
