Species residing across elevational gradients display adaptations in response to environmental changes such as oxygen availability, ultraviolet radiation, and temperature. Here, we study genomic variation, gene expression, long-term adaptation Tibetan Partridge (Perdix hodgsoniae) populations the gradient of Plateau. We generated a high-quality draft genome used it carry out downstream population transcriptomic analysis. The P. hodgsoniae various elevations were genetically distinct, their phylogenetic clustering was consistent with geographic distribution. identified possible evidence flow between <3,000 >4,200 m elevation that is known habitat expansion high-altitude lower elevation. 60 kb haplotype encompassing Estrogen Receptor 1 (ESR1) gene, showing strong genetic divergence hodgsoniae. six single nucleotide polymorphisms within ESR1 fixed for derived alleles are strongly conserved vertebrates. also compared blood transcriptome profiles differentially expressed genes (such GAPDH, LDHA, ALDOC) correlated differences altitude among These candidate from genomics transcriptomics analysis enriched neutrophil degranulation glycolysis pathways, which respond hypoxia hence may contribute high altitudes Our results highlight Partridges useful model molecular mechanisms underlying altitudes.

Bare parts in the Galliformes: the evolution of a multifunctional structure

Royal Society Open Science, Год журнала: 2024, Номер 11(1)

Опубликована: Янв. 1, 2024

A morphological trait can have multiple functions shaped by varying selective forces. Bare parts in birds, such as wattles, casques and combs, are known to function both signalling thermoregulation. Studies demonstrated structures targets of sexual selection via female choice several species Galliformes (junglefowl, turkeys grouse), though other studies shown some role thermoregulation (guineafowl). Here, we tested fundamental hypotheses regarding the evolution maintenance bare Galliformes. Using a phylogeny that included nearly 90% order, evaluated natural shaping across different clades. We found combination environmental putative sexually selected traits strongly predicted variation for males females When analysis is restricted largest family, Phasianidae (pheasants, junglefowl allies), were primary predictors parts. Our results suggest important but primarily under strong within Phasianidae.

UCE-derived mitochondrial phylogeny reveals pervasive mito-nuclear discordances in serotine bats (genus Eptesicus) and complex evolutionary history in Eptesicus (Histiotus)

Mammalian Biology, Год журнала: 2024, Номер 104(4), С. 417 - 430

Опубликована: Май 15, 2024

Abstract Studies of evolution and biodiversity require solid understanding species systematics revealed by molecular phylogeny using multilocus genomic data. Multilocus analyses, nevertheless, remain difficult in non-model taxa due to limited access samples resources. To help overcome this limitation, ultra-conserved elements (UCEs) have been developed generate large nuclear datasets build more robust phylogenies. Recently, MitoFinder pipeline was further extract mitochondrial genes from the off-target sequences UCE libraries allow mito-nuclear comparison increase database. Here we applied published serotine bats (genus Eptesicus ) focused on E. (Histiotus) whose evolutionary history is poorly understood. Our results showed extensive discordances divergence major clades within , indicating potential incomplete lineage sorting historical introgression across subgenera. Moreover, collected several new including first data recently described (H) diaphanopterus combined available most taxa-complete bats. Results supported early (H.) magellanicus status . In addition, found strong evidence cryptic diversity, with potentially Peru, Uruguay, Brazil, which needs be evaluated future studies complementary study enriched sequence database shed light hidden diversity complex

Genes, Год журнала: 2024, Номер 15(6), С. 742 - 742

The Old-World quails, Coturnix coturnix (common quail) and japonica (Japanese quail), are morphologically similar yet occupy distinct geographic ranges. This study aimed to elucidate their evolutionary trajectory ancestral distribution patterns through a thorough analysis of mitochondrial genomes. Mitogenomic revealed high structural conservation, identical translational mechanisms, pressures in both species. Selection significant evidence positive selection across the lineage for nad4 gene tree owing environmental changes acclimatization requirements during its history. Divergence time estimations imply that diversification among species occurred mid-Miocene (13.89 Ma), current distributions were primarily shaped by dispersal rather than global vicariance events. Phylogenetic indicates close relationship between C. japonica, with divergence estimated at 2.25 Ma Pleistocene epoch. Ancestral range reconstructions indicate ancestors clade distributed over Oriental region. subsequently dispersed Eurasia Africa, eastern Asia. We hypothesize result from unique strategies, developed evade interspecific territoriality influenced Tibetan Plateau’s constraints. advances our understanding biogeographic processes leading laying important groundwork further research on this genus.

Inter-glacial isolation caused divergence of cold-adapted species: the case of the snow partridge

Current Zoology, Год журнала: 2021, Номер 68(4), С. 489 - 498

Опубликована: Сен. 6, 2021

Deciphering the role of climatic oscillations in species divergence helps us understand mechanisms that shape global biodiversity. The cold-adapted may have expanded their distribution with development glaciers during glacial period. With retreat glaciers, these were discontinuously distributed high-altitude mountains and isolated by geographical barriers. However, study focuses on speciation process is scant. To fill this gap, we combined population genetic data ecological niche models (ENMs) to explore snow partridge (Lerwa lerwa). Lerwa lerwa a bird from 4,000 5,500 m. We found 2 populations within L. lerwa, they diverged each other at about 0.40-0.44 million years ago (inter-glacial period after Zhongliangan glaciation). ENMs suggested low elevations Himalayas Hengduan period, whereas it contracted high elevations, southern Himalayas, inter-glacial periods. Effective size trajectory also its Consistent our expectation, results support isolation contributed Qinghai-Tibetan Plateau. This deepens understanding how driven Phasianidae mountains.

Deutsche Entomologische Zeitschrift, Год журнала: 2024, Номер 71(1), С. 85 - 109

Опубликована: Март 12, 2024

Here, we describe a new genus of lice (Phthiraptera, Ischnocera) in the Oxylipeurus -complex, parasitising galliform hosts genera Tragopan Cuvier, 1829. This genus, Pelecolipeurus gen. nov. , is separated from other members complex by unique shape male subgenital plate and stylus, genitalia characters. The only previously-known species Lipeurus longus Piaget, 1880, which here tentatively re-described as (Piaget, 1880), based on specimens non-type host, temminckii (Gray, 1831). In addition, species, fujianensis sp. caboti (Gould, 1857). An overview distribution patterns ischnoceran galliforms presented, suggests that host phylogeny, biogeography biotope, well elevation range, may all be important factors have structured louse communities landfowl. We transfer Afrilipeurus -complex to include an emended key -complex.

Characterization of the Complete Mitogenome of the Ring-Necked Pheasant Phasianus colchicus (Galliformes: Phasianidae) and Systematic Implications for Phasianinae Phylogenetics

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

Опубликована: Дек. 4, 2024

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.
