Abstract Chalcidoidea are mostly parasitoid wasps that include as many 500 000 estimated species. Capturing phylogenetic signal from such a massive radiation can be daunting. is an excellent example of hyperdiverse group has remained recalcitrant to resolution. We combined 1007 exons obtained with Anchored Hybrid Enrichment 1048 ultra‐conserved elements (UCEs) for 433 taxa including all extant families, >95% subfamilies, and 356 genera chosen represent the vast diversity superfamily. Going back forth between molecular results our collective knowledge morphology biology, we detected bias in analyses was driven by saturation nucleotide data. Our final based on concatenated analysis least saturated UCE datasets (2054 loci, 284 106 sites). support expected sister relationship Mymarommatoidea.

Abstract The passerine superfamily Certhioidea lacks a complete phylogeny despite decades of recognition as clade and extensive systematic work within all its constituent families. Here, we inferred near-complete species-level from molecular supermatrix, including the first comprehensive sampling wrens (Troglodytidae), used this to infer biogeographic diversification histories. We also an expanded nearly 100 putative phylospecies previously documented in literature, found that diversity had notable impacts on evolutionary history Certhioidea. This phylospecies-level tree few instances species paraphyly, some described literature novel. originated largely Eurasia dispersed into North America five times last 20 million years, at origin “New World certhioids,” gnatcatchers, herein named Orthourae. After initial dispersal event, both gnatcatchers diversified extensively across hemisphere, with lineages repeatedly crossing between continents. However, detected no impact formation Isthmus Panama frequency events South America. inclusion altered inference portions but overall was consistent. With sampling, rates were constant through time detectable deceleration toward present. By contrast, recovered different significant rate increase crown node Orthourae after dispersing Americas increased speciation particularly genera Polioptila Henicorhina. resolved for has yielded important insights group provides framework future comparative fascinating clade.

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.

Phylogenomic approaches have recently helped elucidate various insect relationships, but large-scale comprehensive analyses on relationships within sawflies and woodwasps are still lacking. Here, we infer the long-term biogeographic history of these hymenopteran groups using a large dataset 354 UCE loci collected from 385 species that represent all major lineages. Early Hymenoptera started diversifying during Triassic ∼249 Ma spread over ancient supercontinent Pangaea. We recovered Xyeloidea as monophyletic sister group to other Pamphilioidea Unicalcarida. Within diverse family Tenthredinidae, our taxonomically geographically expanded taxon sampling highlights non-monophyly several traditionally defined subfamilies. In addition, recent removal Athalia related genera Tenthredinidae into separate Athaliidae is supported.

The movement of species to new geographical areas has been proposed be crucial for speciation. As such, dispersal regarded as a likely explanation the variation in richness among clades. Emberizoidea are highly diverse Oscine bird clade native New World that characterized their ubiquitous distribution both ecologically and geographically, making this group ideal test how biogeographical could promote To do so, we relate rates with speciation families using combination bioregionalization analysis, ancestral area reconstruction rate estimation methods. We found superfamily arose from widespread ancestor distributed over World, its range evolution being primarily driven by contraction main cladogenetic events occurring within bioregions. Moreover, demonstrate between bioregions showed no relationship rates, suggesting spaces is not driver group. Instead, individual promoted stability prove an important at broad spatial scales families.

Abstract One of the main goals historical biogeography is understanding where species originated, and how climate change ecological interactions shaped their distribution. The task complicated by both active passive mechanisms, including habitat tracking, separation into metapopulations variably interconnected demes, long‐distance dispersal, which may all obscure geographic signature origin. Current tools use phylogenies to infer area origin (AOO). They work discretizing range occupied distinct areas then applying ancestral character estimation identify at speciation. These methods are powerful can account for different modes Yet, they bound assume that discrete currently faithful representation climatic historic affiliation ignore metapopulation structures. Still, most cannot take advantage fossil information or with extinct species. Although explicit bioclimatic modelling now possible under some implementations, these limitations partly unresolved, burdens accuracy AOO process. We present a new tool written in R, named RRphylogeography , meant find species, locate feasible zones contact between throughout history. starts from identifies potential patches during speciation finds likely represent contact. By using virtual simulations, we compared common tools. found statistically outcompetes alternatives study conditions, reaching especially accurate predictions. additionally used investigate complex phylogeographic history polar bear Ursus maritimus . method placed Northern Beringia.

Abstract During the present study, evolutionary relationship within a clade of mountain freshwater crabs ( Potamonautes ) was examined using mtDNA sequence data for species from Cape Fold Mountain (CFM) and Great Escarpment (Drakensberg range). We undertook phylogenetic analyses, divergence time estimation, an ancestral area reconstruction to explore period cladogenesis understand biogeographic history in this high‐altitude clade. Furthermore, we applied four delimitation methods ASAP, bPTP, bGMYC, STACEY on latter Bayesian analyses retrieved monophyletic crab comprised two major sister clades, one (clade A) Drakensberg Mountains B) species.

Abstract Background and Aims The geographical origin evolutionary mechanisms underpinning the rich distinctive New Caledonian flora remain poorly understood. This is attributable to complex geological past of island scarcity well-resolved species-level phylogenies. Here, we infer phylogenetic relationships divergence times palms, which comprise 40 species. We use this framework elucidate biogeography palm lineages explore how extant species might have formed. Methods A tree including 37 77 relatives from tribe Areceae was inferred 151 nuclear genes obtained by targeted sequencing. Fossil-calibrated were estimated ancestral ranges inferred. Ancestral ecological preferences in terms elevation, precipitation substrate compared between sister their possible roles as drivers speciation. Key Results palms form four well-supported clades, inside are well resolved. Our results support current classification but suggest that Veillonia Campecarpus should be resurrected fail clarify whether Rhopalostylidinae or nested Basseliniinae. derived Guinean Australian ancestors, reached through at least three independent dispersal events Eocene Miocene. Palms then dispersed out Caledonia five times, mainly towards Pacific islands. Geographical transitions associated with speciation differed across time genera.

Abstract The Andean mountains stand out for their striking species richness and endemicity that characterize many emblematic Neotropical clades distributed in or around these mountains. radiation of the Sigmodontinae subfamily, most diversified mammalian group Neotropics, has been historically related to orogenesis. We aim evaluate this interplay between geological processes biological responses through diversification dynamics, biogeographical history, range evolution subfamily. For these, we built comprehensive phylogeny gathered 14,836 occurrences identified one shift speciation rate genus Akodon , which suffered after arrival non-Andean ancestors. Our biogeographic analyses show multiple dispersal paths throughout allowed subfamily colonize all Neotropics. Northern Andes Central-Southern were important sources diversity. In addition, relevant sink, receiving highest number lineages. region exhibited higher turnover rates than regions. Thus, our results support crucial role Mountains radiation, acting as a "macroevolutionary cradle" "species attractor" several sigmodontine lineages at different times, pump" becoming source widely neotropical Then, complex macroevolutionary dynamics would explain rodents' high extant diversity wide distribution
