Resolving a 182-year-old taxonomic puzzle: Luciobarbus in the Persian Gulf basin (Teleostei: Cyprinidae)

Zootaxa, Год журнала: 2025, Номер 5620(1), С. 29 - 71

The species diversity of the genus Luciobarbus in Persian Gulf basin is revisited by integrating morphological, mitochondrial, and nuclear genomic data. Three are recognised: esocinus, L. schejch, subquincunciatus. Barbus rajanorum a hybrid between schejch Capoeta damascina. mystaceus described from Caspian basin, identified Heckel (1843) as Tigris Qweiq schejch. barbulus junior synonym kersin likely conspecific, First Revisers, we give priority to over kersin. syntypes xanthopterus hybrids esocinus name unavailable, was already treated Fishes barbulus, pectoralis, Euphrates drainages all pectoralis endemic Mediterranean basin. cannot be their mtDNA they have widely hybridised. hosts two types mtDNA; few species-specific, but most individuals esocinus. genome-wide SNP data produced for confirms existence clusters (L. schejch), demonstrating variable extent hybridisation both, agreeing with morphology.

Genomic Footprints of Ancient Multi‐Species Introgression Events Among Allopatric Australo‐Papuan Butcherbird Species

Journal of Biogeography, Год журнала: 2025, Номер unknown

Опубликована: Апрель 11, 2025

ABSTRACT Aim Climate change has influenced the evolution of world's biota, shaping species distributions, promoting diversification and causing extinctions. The turbulent climatic oscillations Pleistocene, which caused repeated periods isolation secondary contact, have left lasting signatures on genomes across world. resultant reticulate histories are difficult to untangle, yet offer unique insights, capturing responses climate that would otherwise be undetected providing empirical case‐studies impact introgression tens thousands years later. Here, we explore such dynamics using three currently allopatric Australian butcherbirds. We specifically test long‐standing biogeographic hypotheses concerning role intermittent Pleistocene land‐bridges in facilitating contact. Location Australia New Guinea. Taxon Silver‐backed Butcherbird Cracticus argenteus , Black‐backed mentalis Grey torquatus (Passeriformes: Artamidae). Methods generated genomic data from museum specimens infer relationships, taxonomic boundaries elucidate history gene flow this complex. Results uncovered evidence multiple ancient introgressions into savannah‐adapted C. both more arid‐tolerant despite their current allopatry. This supports Arafura Shelf maintaining genetic connectivity between Guinea expansion aridity during glacial maxima range expansions species. Main Conclusions Our showcase how retained over generations can reveal unexpected insights about evolutionary history, as well expand our understanding guilds similarly adapted may responded concordantly paleoclimate change. These important implications for biodiversity conservation, increasing contact driven by might future.

Multiple instances of river-lake introgression in the adaptive radiation of sailfin silversides in Wallace’s Dreampond

bioRxiv (Cold Spring Harbor Laboratory), Год журнала: 2025, Номер unknown

Опубликована: Апрель 18, 2025

Abstract While adaptive radiations significantly contribute to the world’s biodiversity, much is unknown about genetic and ecological factors underlying these rapid successions of speciation. It has been suggested that hybridisation can facilitate speciation process by generating diversity on which diversifying selection act. Sailfin silverside fishes (Telmatherinidae) in Malili Lakes system Sulawesi have diversified within last 2 million years. We assembled annotated a chromosome-scale reference genome riverine sailfin Telmatherina bonti generated whole sequences all species Lake Matano, South Sulawesi, Indonesia, one oldest deepest lakes. reconstructed phylogenetic relationships radiation silversides inferred past ongoing introgression patterns. Genome-wide tests confirmed two monophyletic clades, sharpfins roundfins. However, we found mismatches between morphology-based taxonomic assignments genome-wide relationships. signs both old river-dwelling T. lacustrine sharpfin group, as shown elevated D-statistic, f4-ratio f-branch statistic. Levels excess allele sharing three most common declined with increasing distance from river-inlet, indicating at lake-river interface. This combination radiating flock makes Matano particularly valuable study fundamental mechanisms driving under genomic exchange. The phylogenomic framework elaborated this provides foundation for studies processes shaping charismatic radiation.

Frequent Hybridisation Between Parapatric Lekking Bird‐of‐Paradise Species

Molecular Ecology, Год журнала: 2025, Номер unknown

ABSTRACT Hybridisation is known to occur between a wide range of taxa, including species for which strong sexual selection has led markedly different phenotypes and lek‐mating behaviours. To what extent occasional hybridisation can overcome the reproductive barriers in such systems and, example, lead establishment hybrid zones poorly known. In this study, we address question by focusing on one most well‐known avian radiations resulted an extraordinary assemblage phenotypic diversity behaviours: birds‐of‐paradise ( Paradisaeidae ). We quantify genome‐wide distribution introgression find multiple signals recent historical gene flow within two genera birds‐of‐paradise, Astrapia Paradigalla . addition, present first empirical genomic indication putative zone lekking bird‐of‐paradise that differ substantially their sexually selected traits Our findings are consistent with idea behavioural may constitute weaker pre‐ post‐zygotic than generally thought species.

Replicate geographic transects across a hybrid zone reveal parallelism and differences in the genetic architecture of reproductive isolation

Evolution Letters, Год журнала: 2025, Номер unknown

Опубликована: Апрель 1, 2025

Abstract Determining the genetic architecture of traits involved in adaptation and speciation is one key components understanding evolutionary mechanisms behind biological diversification. Hybrid zones provide a unique opportunity to use admixture identify loci contributing partial reproductive barriers between taxa. Many studies have focused on temporal dynamics hybrid zones, but geographical variation that span distinct ecological contexts has received less attention. We address this knowledge gap by analyzing hybridization introgression black-capped Carolina chickadees two geographically remote transects across their extensive zone, located eastern central North America. Previous demonstrated zone moving northward as result climate change staying consistently narrow due selection against hybrids. In addition, ~5× slower America compared more regions, reflecting continent-wide rate change. whole genome sequencing 259 individuals assess whether movement reflected patterns introgression, which genes genomic regions show restricted contexts. Our results highlight substantial similarities reveal large Z-linked chromosomal rearrangements generate measurable differences degree gene flow transects. further simulations analyses climatic data examine potential factors continental-scale nuances pressures. discuss our findings context importance sex chromosome inversions other species.

Historical biogeography of North American killifishes (Cyprinodontiformes) recapitulates geographical history in the Gulf of México watershed

Zoological Journal of the Linnean Society, Год журнала: 2024, Номер 202(2)

Опубликована: Окт. 1, 2024

Abstract We analysed phylogenetic relationships within a major clade of Cyprinodontiformes (Teleostei) that includes five families North American killifishes. used DNA sequences from genes for 130 species, with four fossil calibrations and three secondary calibrations, to generate time-calibrated phylogeny. estimated diversification rates, ancestral areas, habitats each node. Findings were interpreted detailed biogeographical synthesis. The results indicate the arose in Eocene along Gulf México coast. speciation rate was uniform through time, except acceleration Cyprinodontidae after ~10.9 Mya. In other families, neither viviparity nor marine-to-freshwater transition associated accelerated speciation. Sea-level fluctuations might have created pump by stimulating cycles dispersal vicariance Diversification also included many cases inland immigration coastal ancestors. For upland lineages, ancient river drainages accord lineage distributions, including enigmatic disjunctions Goodeidae Fundulus. uplands occurred via barrier displacement alluvial or tectonically active landscapes. Killifishes display high environmental tolerance persist harsh, peripheral environments unsuitable most fishes. Hence, combination antiquity, adaptability, dynamic geography, persistence can explain living diversity New World
