The millipede family Siphonorhinidae (order Siphonophorida) shows a scattered distribution in South Africa, Madagascar, India, Southeast Asia, and North America. So far, the is unknown from America, while species of Siphonophoridae, second order, are relatively abundant on continent. However, not single Siphonophorida known Chile. Here we describe monotypic genus Notorhinus gen. nov. with N. floresi sp. record (undescribed) species, as first records order Chile distinct remaining by arrangement sensilla basiconica antennae other somatic sexual characters. it close morphological affinities to American Illacme Cook Loomis 1928. In Americas were previously only California (USA), where they inhabit subterranean micro-habitats. Chilean was found under piece decaying wood small patch fragmented native forest. Thus, group disjunct antitropical America at ca. 37° 38° South. They might be relict once greater distribution, which persisted these areas due similar climatic conditions.

Abstract The megadiverse genus Carex (c. 2000 species, Cyperaceae) has a nearly cosmopolitan distribution, displaying an inverted latitudinal richness gradient with higher species diversity in cold‐temperate areas of the Northern Hemisphere. Despite great expansion our knowledge phylogenetic history and many molecular studies focusing on biogeography particular groups during last few decades, global analysis diversification is still lacking. For this purpose, we built hitherto most comprehensive Carex‐ dated phylogeny based three markers (ETS–ITS– matK ), using previous phylogenomic Hyb‐Seq framework, sampling two‐thirds its all recognized sections. Ancestral area reconstruction, biogeographic stochastic mapping, rate analyses were conducted to elucidate macroevolutionary patterns. Our results reveal that originated late Eocene E Asia, where it probably remained until synchronous main subgeneric lineages Oligocene. Asia supported as cradle diversification, well “museum” extant diversity. Subsequent “out‐of‐Asia” colonization patterns feature multiple asymmetric dispersals clustered toward present times among Hemisphere regions, major regions acting both source sink (especially North America), several independent events Southern We detected 13 notable shifts 10 My, including remarkable radiations America New Zealand, which occurred concurrently Neogene cooling, suggests involved new into novel niche space.

Abstract Premise Astragalus (Fabaceae), with more than 3000 species, represents a globally successful radiation of morphologically highly similar species predominant across the northern hemisphere. It has attracted attention from systematists and biogeographers, who have asked what factors might be behind extraordinary diversity this important arid‐adapted clade sets it apart close relatives far less richness. Methods Here, for first time using extensive phylogenetic sampling, we whether (1) is uniquely characterized by bursts or diversification instead uniform no different closely related taxa. Then tested attributable specifically to its predilection (2) cold arid habitats, (3) particular soils, (4) chromosome evolution. Finally, (5) originated in central Asia as proposed (6) niche evolutionary shifts were subsequently associated colonization other continents. Results Our results point importance heterogeneity , upshifts earliest divergences but not strongly tied any abiotic factor biogeographic regionalization here. The only potential correlate identified was number. Biogeographic strong association environment highlight gateway. Conclusions investigation shows studies logistically challenging “mega‐radiations.” findings reject simple key innovation high underline often nuanced, multifactorial processes leading species‐rich clades.

Premise Although numerous phylogenetic studies have been conducted in Cactaceae, whole‐plastome datasets not employed. We used the chollas to develop a plastome dataset for phylogeny reconstruction test species relationships, biogeography, clade age, and morphological evolution. Methods developed most known diploid members of (42 taxa) as well other Cylindropuntieae. Paired‐end, raw reads from genome skimming were reference‐mapped onto de novo assembly one cholla, Cylindropuntia bigelovii , build our dataset, which was analyzed using various methods. Results Our resolved chollas, including interspecific intraspecific relationships. Tribe Cylindropuntieae arose ~18 mya, during early Miocene southern South America, is supported sister American Tephrocacteae. The ( Micropuntia + Grusonia )) likely originated Chihuahuan Desert region around 16 mya then migrated into North desert regions. Key characters recognizing traditional taxonomic series (e.g., spiny fruit) are mostly homoplasious. Conclusions This study provides first comprehensive any within Cactaceae. s.l. widespread throughout western deserts, their recent common ancestor mid‐Miocene, with much diversity arising mid‐Pliocene, pattern strikingly similar those found groups.

The liquorice genus, Glycyrrhiza L. (Leguminosae), is a medicinal herb with great economic importance and an intriguing intercontinental disjunct distribution in Eurasia, North Africa, the Americas, Australia. Glycyrrhiza, along Glycyrrhizopsis Boiss. Meristotropis Fisch. & C.A.Mey., comprise s.l. Here we reconstructed phylogenetic relationships biogeographic history using sequence data of whole chloroplast genomes. We found that sister to tribe Wisterieae divided into four main clades. Clade I, corresponds sensu Meng. embedded within Meng, these two genera together form Clades II-IV. Based on analyses divergence time dating, originated during late Eocene its most recent common ancestor (MRCA) was distributed interior Eurasia circum-Mediterranean region. A vicariance event, which possibly response uplifting Turkish-Iranian Plateau, may have driven between Meng Middle Miocene. third fourth uplift events Qinghai-Tibetan Plateau led rapid evolutionary diversification Subsequently, MRCA II might migrated America (G. lepidota) via Bering land bridge early Pliocene, reached temperate South astragalina) by long-distance dispersal (LDD). Within III, G. acanthocarpa arrived at southern Australia through LDD after whereas all other species (the SPEY clade) Mediterranean region Pleistocene.

Bipolar disjunct distributions are a fascinating biogeographic pattern exhibited by about 30 vascular plants, whose populations reach very high latitudes in the northern and southern hemispheres. In this review, we first propose new framework for definition of bipolar disjunctions then reformulate list guiding principles to consider how study species. Vicariance convergent evolution hypotheses have been argued explain origin fragmented distribution pattern, but show here that they can be rejected all species, except Carex microglochin . Instead, human introduction dispersal (either direct or mountain‐hopping) — facilitated standard nonstandard vectors most likely explanations plant disjunctions. Successful establishment after is key colonization areas appear related both intrinsic (e.g., self‐compatibility) extrinsic (mutualistic antagonistic interactions) characteristics. Most studies on conducted (Cyperaceae), genus plants with largest number We found predominant north‐to‐south direction dispersal, an estimated time diversification agreement major cooling events during Pliocene Pleistocene. species do not seem depend specialized traits long‐distance could dispersed through one multiple stochastic events, birds as vector.

Methods carried out phylogenomic dating under two different clock models used multiple strategies vary matrix composition, evaluating overlapping divergence times estimated across using Bhattacharyya coefficients. Lastly, we reconstructed biogeographic history a Bayesian implementation DEC model. Results Eucerinae started diversifying during Palaeocene, all its tribes originating Palaeocene/Eocene transition southern South America. At least range expansions happened into North America before full closure Isthmus Panama. show that between groups disjunct distributions would periods when climate favoured expansion open habitats became isolated forests were re‐established. Main conclusions describe early diversification bees, revealing an intimate association Events evolution likely affected global cooling aridification, palaeoclimatic vegetational conditions probably been more relevant formation than consolidation Panama connecting Americas. also demonstrate uncertainty time estimation not due amount molecular data being used, other factors like fossil calibrations violations models.

Abstract Premise Pectocarya recurvata (Boraginaceae, subfamily Cynoglossoideae), a species native to the Sonoran Desert (North America), has served as model system for suite of ecological and evolutionary studies. However, no reference genomes are currently available in Cynoglossoideae. A high‐quality genome P. would be valuable addressing questions this across broader taxonomic scales. Methods Using PacBio HiFi sequencing, we assembled annotated coding regions with full‐length transcripts from an Iso‐Seq library. We assessed completeness BUSCO k ‐mer analysis, estimated size six individuals using flow cytometry. Results The chromosome‐scale assembly was 216.0 Mbp long (N50 = 12.1 Mbp). Previous observations indicated is 2 n 24. Our included 12 primary contigs (158.3 Mbp) containing 30,655 genes telomeres at 23 out 24 ends. Flow cytometry measurements same population two plants 1C 196.9 Mbp, smallest measured Boraginaceae, four 385.8 which consistent tetraploidy population. Discussion annotation provide genomic resource sparsely represented area angiosperm phylogeny. This new will facilitate answering open ecophysiology, biogeography, systematics.
