Genes, Год журнала: 2024, Номер 15(12), С. 1569 - 1569

Background: Phasianidae mitogenomes exhibit significant structural variations critical for understanding evolution and subspecies divergence. However, annotations of these features in some pheasant species remain limited. This study aimed to enhance their evolutionary patterns. Methods: A comparative analysis complete from Phasianus colchicus, versicolor, 22 other accipitrids was conducted, examining codon usage, rRNA structures, selective pressures, phylogenetics, variations. Results: The mitogenome P. colchicus is 16,696 bp, comprising 13 protein-coding genes, 2 tRNA a control region, with base composition A: 30.61%, T: 25.26%, C: 30.85%, G: 13.28%. Phylogenetic revealed versicolor are closely related, the following relationship: ((Phasianus + Chrysolophus) (Crossoptilon Lophura)). Divergence timing aligns Tibetan Plateau uplift during Tertiary Pliocene. Ka/Ks suggests CO I, II, III, ND1, ND4L, ND6 genes underwent strong pressure plateau adaptation. Conclusions: confirms monophyly its close relationship Chrysolophus. Adaptation-related pressures on highlight role environments, offering valuable insights into phylogeny.

Species of Reticulipeurus Kéler, 1958 (Phthiraptera, Ischnocera, Oxylipeurus-complex) parasitic on species of Arborophila, with description of a new subgenus and three new species

Zootaxa, Год журнала: 2023, Номер 5284(3), С. 496 - 520

A new subgenus and three species of parasitic lice (Phthiraptera: Ischnocera) in the Oxylipeurus-complex are described illustrated. Forcipurellus is part genus Reticulipeurus Kéler, 1958, only includes on partridges Arborophila Hodgson, 1837. The are: (Forcipurellus) diki ex rubrirostris (Salvadori, 1879); bracatus atrogularis (Blyth, 1849); longistylus rufogularis guttata Delacour & Jabouille, 1928 two other host subspecies. In addition, we redescribe formosanus (Uchida, 1917) crudigularis (Swinhoe, 1864) nitzschi 1958 torqueola (Valenciennes, 1825) millardi (Baker, 1921). Also, briefly discuss four additional that could not be based specimens examined. key to identify all provided, as well an emendation include a previously published Oxylipeurus-complex.

The draft genome of the Tibetan partridge (Perdix hodgsoniae) provides insights into its phylogenetic position and high-altitude adaptation

Journal of Heredity, Год журнала: 2022, Номер 114(2), С. 175 - 188

Abstract The Tibetan partridge (Perdix hodgsoniae) is a widely distributed endemic species in high-altitude areas across the Plateau where hypoxia, lower temperature and high ultraviolet radiation are pivotal factors influencing survival. However, underlying genetic adaptation of to extreme environments remains uncertain due limited genomic resources. Similarly, phylogenetic position Perdix within Phasianidae controversial lacking information. Consequently, we de novo assembled annotated whole genome partridge. size was 1.15 Gb with contig N50 3.70 Mb. A total 202.30 Mb (17.61%) repetitive elements 445,876 perfect microsatellites were identified. 16,845 functionally protein-coding genes identified Genomic analysis 30 Galliformes indicated close relationship between typical pheasants composed Chrysolophus, Symaticus, Phasianus, Crossopilon, Lophura. + (Chrysolophus (Syrmaticus other pheasants))) different from those previous studies.

Abstract Asteriornis maastrichtensis , from the latest Cretaceous of Belgium, is among oldest known crown bird fossils, and its three-dimensionally preserved skull provides most substantial insights into cranial morphology early birds to date. Phylogenetic analyses recovered as a total-group member Galloanserae (the clade uniting Galliformes Anseriformes. One important feature supporting this placement was enlargement retroarticular processes, which form elongate caudal extensions mandible in extant Galloanserae. Here, we reinterpret jaw illustrate that caudalmost portion mandibles are fact not preserved. Instead, extremities both left right mandibular rami extend surface fossil block containing holotype skull, where they have eroded away. The originally identified process mandible—which exhibits orientation strikingly similar processes certain galloanserans, including Palaeogene total-clade anseriforms Conflicto Nettapterornis— instead represents twisted caudally displaced medial process. Nonetheless, anatomical comparisons with taxa reveal unable exclude possibility exhibited robust comparable those In light reinterpreted mandible, update original character matrix used investigate phylogenetic relationships, our revised continue support position galloanseran, initially interpreted. We demonstrate additional morphological traits provide new data on nature distribution birds.
