The partitioning of global biodiversity into biogeographic regions is critical for understanding the impacts global-scale ecological and evolutionary processes on species assemblages as well prioritizing areas conservation. However, lack globally comprehensive data distributions precludes fine-scale estimation biogeographical regionalization numerous taxa ecological, economic conservation interest. Using a recently published phylogeny novel curated native range maps over 10 000 butterflies around world, we delineated world’s using phylogenetic dissimilarity. We uncovered 19 distinct phylogenetically delimited (phyloregions) nested within 6 realms. Regional boundaries were predicted by spatial turnover in modern-day temperature precipitation seasonality, but historical climate change also left pronounced fingerprint deeper- (realm-) level boundaries. use culturally ecologically important group insects to expand our how contemporary factors drive distribution organismal lineages Earth. As more generally face unprecedented challenges from anthropogenic factors, research provides groundwork conservation, especially with goal preserving legacies biosphere’s history.

Phylogenetic evidence clarifies the history of the extrusion of Indochina

The southeastward extrusion of Indochina along the Ailao Shan-Red River shear zone (ARSZ) is one two most prominent consequences India-Asia collision. This plate-scale has greatly changed Southeast Asian topography and drainage patterns effected regional climate biotic evolution. However, little known about how was extruded toward southeast over time. Here, we sampled 42 plant animal clades (together encompassing 1,721 species) that are distributed across ARSZ not expected to disperse long distances. We first assess possible role on driving phylogenetic separations observed ARSZ. then investigate temporal dynamics through a multitaxon analysis. show lineage divergences were likely associated with Indochinese rather than climatic events. began at ~53 Ma increased sharply ~35 Ma, peaks ~19 ~7 valley ~13 Ma.

ABSTRACT Aim We examine the phylogeographic genetic structure of endangered pig‐nosed turtle Carettochelys insculpta , last remaining member a once globally widespread family, now restricted to northern Australia and southern New Guinea, region with complex geological eustatic history. their historical biogeography, demographic history status threatened populations. Location Northern Australia, Southern Guinea. Methods reconstruct phylogenetic relationships patterns diversity using genome‐wide dataset 15,081 single nucleotide polymorphisms two mitochondrial loci from samples spanning full species' range. Results The Australian, Papua Guinea Indonesian turtles are recovered as three distinct lineages; Australian lineage diverged lineages ca 660 Kya, while Province 564 Kya. Although fossil record shows that C. has been long‐standing representative fauna (since at least Miocene), extant later in Middle Pleistocene. Both were likely shaped by bottlenecks, isolation drift, which greatly reduced effective population sizes 48–88. Main Conclusions contemporary is most consistent vicariance model whereby large interchanging occupying came be fragmented into lineages. Subsequent dispersal via paleodrainages submerged continental shelf under influence Pleistocene sea‐level change thought have impeded Akimeugah Arafura Basins. All populations show low without gene flow, suggesting they vulnerable inbreeding fitness, requiring consideration rescue.

Phylogenetic and biogeographic reconstruction of Lamiini sensu lato (Coleoptera, Cerambycidae) reveals South Gondwanan origin and Panthalasso-Tethyan dispersal pathways

Biosystems Diversity, Год журнала: 2025, Номер 33(1), С. e2510 - e2510

In this study I conduct the phylogenetic and biogeographical analysis of Lamiini sensu novo (Coleoptera, Cerambycidae, Lamiinae), confirming it as a monophyletic group that is broader than previously assumed supporting redefinition unified tribe – novo. The consist eight major clades (TAENI, DORCA, ACALO, BATOC, PSACO, ANOLPL, MONOC, LAMIA) integrates together several traditionally recognized tribes (Dorcaschematini, Batocerini, Petrognathini, Rhodopini, Monochamini, Dorcadionini, Phrissomini). Most them, including Phrissomini are polyphyletic, representing multiple lineages with intricate evolutionary history. Phylogeographic suggests South Gondwanan origin s. l., its ancestral lineage (LaCA) emerging in Antarctica–South America suture zone before global expansion through three key migration routes: northeast Pantalassic, Trans-Tethyan, southwest Pantalassic. Continental drift climate oscillations influenced process. Initial diversification (~70–60 Ma) led to vicariant taxa due continental isolation, basal ACALO) distributed across America, North Australia. Extinction events, K–T boundary (~66 Cenozoic glaciations, further shaped diversification. rise BATOC PSACO marked early crown-group l. within island continent Greater India archipelagos Trans-Tethyan Arc (~60–50 Ma). collision Asia (~50–45 facilitated faunal exchanges, aiding dispersal into Africa Southeast driving ANOPL (45–35 ACALO clade underwent secondary during initial Australia Eurasia (~25–20 Ma), coinciding uplift New Guinea Miocene. LAMIA likely originated East During Miocene Climatic Optimum, expanded via Gomphotherium Land Bridge (~16 colonized Europe. Later cooling aridification (~5–11 drove diversification, particularly Eurasian steppes. MONOC also Asia, adapting montane coniferous forests cooling. It spread glaciations (~20 Ma, ~14 entered Beringia. Expansion Mesoamerica, northern Caribbean occurred Pleistocene (~0.01–2 when fluctuating sea levels enabled dispersal. summary, findings refine phylogeny highlight impact geological climatic events on evolution. This clarifies taxonomic ambiguities provides framework for future research biogeographic patterns.

Molecular and acoustic evidence for large-scale underestimation of frog species diversity on New Guinea

Frontiers of Biogeography, Год журнала: 2025, Номер 18

Опубликована: Май 8, 2025

Species are fundamental units in biology; however, information on species diversity and distribution remain scarce for most taxonomic groups, especially tropical rainforests. Such knowledge gaps particularly acute amphibians, the threatened group of vertebrates, which new continue to be described at a high rate. Herein, using molecular-based approaches, we provide estimates frogs (Anura) New Guinea nearby islands, one biologically diverse regions world. We first characterised geographic sampling all available mitochondrial DNA sequences from native frog species. This led us identify important molecular western half that partially filled by adding 534 (16S rRNA). Large territories uncharted, westernmost part central cordillera Guinea. Using our 16S rRNA dataset, then delimited Molecular Operational Taxonomic Units (MOTUs), subset was bioacoustically analysed. From total 369 MOTUs, found 190 could not assigned any taxon. Amongst these, 123 represented specimens collected 19 were supported as distinct bioacoustics, confirming this portion island is home many unrecognised Based estimated level undescribed taxa areas data available, extrapolate neighbouring islands host 800–1,200 species, with only 560 date. assembled comprehensive dataset date rRNA) islands. candidate bioacoustic data. actual number between 800 1,200.

Abstract Understanding the profound influence of climatic and tectonic histories on adaptation speciation is a crucial focus in biology research. While voyages like Humboldt’s expedition shaped our understanding adaptation, origin current biodiversity remains unclear – whether it arose situ or through dispersal from analogous habitats. Situated geologically complex Australopacific region, study focuses Limbodessus diving beetles (Dytiscidae), diverse genus distributed underground aquifers Western Australia to alpine meadows New Guinea. Using low-coverage whole-genome sequencing, we established time-calibrated phylogenetic tree, elucidating ’ mid-late Miocene, most likely Sahul continent (i.e., Guinea) western Pacific archipelagos. Our results provide evidence for parallel colonization at extreme altitudinal ends, driven by aridification Australia, influencing subterranean colonization, diversification taxa passive-uplifting local biota Furthermore, findings highlight instances isolated aquifers, marked recurrent independent colonizations this habitat.
