Undetected invalid species (i.e., synonyms) can impair inferences we make in biodiversity research and hamper the implementation of effective conservation strategies. However, the processes leading to the accumulation of invalid names remain largely unknown. Using multi-model inferences, we investigated the patterns and potential drivers of species- and assemblage-level variation in synonym counts across terrestrial vertebrates globally. We also explored how taxonomic uncertainty (i.e., instability in species identities) can affect latitudinal variation of diversification rates. The average number of synonyms was higher for species described earlier, better represented in scientific collections, with larger geographic ranges, occurring in temperate regions, and in areas of high biodiversity attention. In assemblage-level models, a higher average number of synonyms was associated with temperate regions harbouring more early-described species. Areas of high endemism richness showed fewer synonyms across amphibians and reptiles but had an inverse effect for birds and mammals. Other predictor-response relationships varied across taxonomic groups, biogeographical realm, and spatial grain. Assuming that more synonyms indicate more stable species that have been thoroughly studied and reviewed, high synonym numbers in temperate species and assemblages support claims of a potential latitudinal taxonomy gradient, where geographic variation in taxonomic practice could hinder the proper recognition of tropical species. We show that the accumulation of invalid names is not random and discuss how invalid hidden names can affect biodiversity inferences. A potential approach to address this problem would be developing a taxonomic uncertainty metric that could be incorporated into models (i.e., as weights to account for varying degrees of uncertainty during the fitting process). Our study provides an initial approximation and highlights the often-neglected issue of uncertainty and instability in species identities from a macroecological perspective.","PeriodicalId":22120,"journal":{"name":"Systematic Biology","volume":"1861 3 1","pages":""},"PeriodicalIF":6.5,"publicationDate":"2025-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143417492","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the importance of this group of fungi, our understanding of their evolution is still limited due to insufficient taxon sampling. Although next-generation sequencing technology allows us to obtain complete genomes for phylogenetic analyses, generating complete genomes of fungal species can be challenging, especially when fungi occur in symbiotic relationships or when the DNA of rare herbarium specimens is degraded or contaminated. Additionally, assembly, annotation, and gene extraction of whole-genome sequencing data require bioinformatics skills and computational power, resulting in a substantial data burden. To overcome these obstacles, we designed a universal target enrichment probe set to reconstruct the phylogenetic relationships of filamentous ascomycetes at different phylogenetic levels. From a pool of single-copy orthologous genes extracted from available Pezizomycotina genomes, we identified the smallest subset of genetic markers that can reliably reconstruct a robust phylogeny. We used a clustering approach to identify a sequence set that could provide an optimal trade-off between potential missing data and probe set cost. We incorporated this probe set into a user-friendly wrapper script named UnFATE (https://github.com/claudioametrano/UnFATE) that allows phylogenomic inferences without requiring expert bioinformatics knowledge. In addition to phylogenetic results, the software provides a powerful multilocus alternative to ITS-based barcoding. Phylogeny and barcoding approaches can be complemented by an integrated, pre-processed, and periodically updated database of all publicly available Pezizomycotina genomes. The UnFATE pipeline, using the 195 selected marker genes, consistently performed well across various phylogenetic depths, generating trees consistent with the reference phylogenomic inferences. The topological distance between the reference trees from literature and the best tree produced by UnFATE ranged between 0.10 and 0.14 (nRF) for phylogenies from family to subphylum level. We also tested the in vitro success of the universal baits set in a target capture approach on 25 herbarium specimens from ten representative classes in Pezizomycotina, which recovered a topology congruent with recent phylogenomic inferences for this group of fungi. The discriminating power of our gene set was also assessed by the multilocus barcoding approach, which outperformed the barcoding approach based on ITS. With these tools, we aim to provide a framework for a collaborative approach to build robust, conclusive phylogenies of this important fungal clade.","PeriodicalId":22120,"journal":{"name":"Systematic Biology","volume":"65 1","pages":""},"PeriodicalIF":6.5,"publicationDate":"2025-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143417538","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods introduced over the past decade have paved the way for a renewed enthusiasm for exploring modes of speciation in the fossil record. However, the field does not yet have a strong intuition for how ancestor-descendant relationships, especially those that arise from budding speciation, might influence the shape of trees reconstructed for fossil or living clades. We developed a simulation approach based on classic paleobiological theory to ask what proportion of ancestral nodes in paleontological phylogenies are expected to correspond to sampled taxa under a range of preservational regimes. We compared our simulated results to empirical estimates of absolute fossil record completeness gathered from the literature and found that many fossilized clades of marine invertebrates are likely to display upwards of 80% sampled ancestors. Under a primarily budding model, phylogenies where 100% of the internal nodes correspond to named species are very possible for well-sampled clades at local and regional scales. We also leveraged our simulation approach to ask how budding might shape extant clades. We found that the ancestral signature of budding causes rampant hard polytomies (i.e., multifurcations), greatly impacting the shape of extant clades. Our results highlight how budding can yield dramatic and unrecognized effects on phylogenetic reconstruction of clades of both living and extinct organisms.","PeriodicalId":22120,"journal":{"name":"Systematic Biology","volume":"65 1","pages":""},"PeriodicalIF":6.5,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143417539","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has been shown that in some subclasses of such models, different sets of rates can result in the same distributions of reconstructed phylogenetic trees, and therefore, the rates become unidentifiable from the trees regardless of their size. Here, we show that widely used time-dependent fossilized birth-death (FBD) models are identifiable. This subclass of models makes more realistic assumptions about the fossilization process and certain infectious disease transmission processes than the unidentifiable birth-death sampling models. Namely, FBD models assume that sampled lineages stay in the process rather than being immediately removed upon sampling. The identifiability of the time-dependent FBD model justifies using statistical methods that implement this model to infer the underlying temporal diversification or epidemiological dynamics from phylogenetic trees or directly from molecular or other comparative data. We further show that the time-dependent FBD model with an extra parameter, the removal after sampling probability, is unidentifiable. This implies that in scenarios where we do not know how sampling affects lineages, we are unable to infer this extra parameter together with birth, death, and sampling rates solely from trees.</p>","PeriodicalId":22120,"journal":{"name":"Systematic Biology","volume":" ","pages":"112-123"},"PeriodicalIF":6.1,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11997801/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142475252","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we inferred the relationships of key lineages within Bivalvia using matrices generated from specifically designed ultraconserved elements (UCEs) with 16 available genomic resources and 85 newly sequenced specimens from 55 families.

The resolution increased when analyzing specific matrices for Pteriomorphia and Imparidentia.

However, a recent study using tetrapod mitochondrial genomes to control for biological sources of variation due to their haploid, uniparentally inherited, and non-recombining nature found that levels of discordance among mitochondrial gene trees were comparable to those found in studies that assume only biological sources of variation. Additionally, they found that several of the models of sequence evolution chosen to infer gene trees were doing an inadequate job of fitting the sequence data. These results indicated that significant amounts of gene tree discordance in empirical data may be due to poor fit of sequence evolution models and that more complex and biologically realistic models may be needed. To test how the fit of sequence evolution models relates to gene tree discordance, we analyzed the same mitochondrial data sets as the previous study using 2 additional, more complex models of sequence evolution that each include a different biologically realistic aspect of the evolutionary process: A covarion model to incorporate site-specific rate variation across lineages (heterotachy), and a partitioned model to incorporate variable evolutionary patterns by codon position. Our results show that both additional models fit the data better than the models used in the previous study, with the covarion being consistently and strongly preferred as tree size increases.

The genus underwent a burst of diversification soon after the divergence of the Neotropical lineage, followed by an exponential decline in diversification rate toward the present. The ancestral host repertoire included the legume genera Astragalus and Trifolium but later expanded to include a wide range of Fabaceae genera and plants in more distantly related families, punctuated with periods of host range expansion and contraction.

For instance, hybridization, a common phenomenon where interbreeding between 2 species leads to formation of a new species, must be depicted by a phylogenetic network, a structure that modifies a phylogenetic tree by allowing 2 branches to merge into 1, resulting in reticulation. However, existing methods for estimating networks become computationally expensive as the dataset size and/or topological complexity increase. The lack of methods for scalable inference hampers phylogenetic networks from being widely used in practice, despite accumulating evidence that hybridization occurs frequently in nature. Here, we propose a novel method, PhyNEST (Phylogenetic Network Estimation using SiTe patterns), that estimates binary, level-1 phylogenetic networks with a fixed, user-specified number of reticulations directly from sequence data. By using the composite likelihood as the basis for inference, PhyNEST is able to use the full genomic data in a computationally tractable manner, eliminating the need to summarize the data as a set of gene trees prior to network estimation. To search network space, PhyNEST implements both hill climbing and simulated annealing algorithms. PhyNEST assumes that the data are composed of coalescent independent sites that evolve according to the Jukes-Cantor substitution model and that the network has a constant effective population size. Simulation studies demonstrate that PhyNEST is often more accurate than 2 existing composite likelihood summary methods (SNaQand PhyloNet) and that it is robust to at least one form of model misspecification (assuming a less complex nucleotide substitution model than the true generating model). We applied PhyNEST to reconstruct the evolutionary relationships among Heliconius butterflies and Papionini primates, characterized by hybrid speciation and widespread introgression, respectively.

These ecomorphologies are ancient and have apparently been transmitted repeatedly between lineages through introgression. Geographically proximate populations of both phenotypes exhibit admixture, and at least 2 black-bellied lineages have been produced via reticulations between shovel-nosed parentals, suggesting potential hybrid speciation dynamics. However, computational constraints currently limit our ability to reconstruct network radiations from gene-tree data. Available methods are limited to level-1 networks wherein reticulations do not share edges, and higher-level networks may be non-identifiable in many cases. We present a heuristic approach to recover information from higher-level networks across a range of potentially identifiable empirical scenarios, supported by theory and simulation. When extrinsic information indicates the location and direction of reticulations, our method can successfully estimate a reduced possible set of nonlevel-1 networks. Phylogenomic data support a single backbone topology with up to 5 overlapping hybrid edges in the Pisgah clade. These results suggest an unusual mechanism of ecomorphological hybrid speciation, wherein a binary threshold trait causes some hybrid populations to shift between microhabitat niches, promoting ecological divergence between sympatric hybrids and parentals.
