The result of heterospecific mating depends upon the effectiveness of pre- and post-reproductive barriers. Incomplete reproductive barriers lead to introgression of DNA into one species or both. Intricate genital morphology among dragonflies provides little assurance of species specificity given that heterospecific mating or mating attempts have been observed among many species. The genetic consequence is unknown for many heterospecific matings. For example, <i>Somatochlora</i> species mating and genetic exchange have been hypothesized based on observational records and individuals with hybrid morphology. We investigate the potential of heterospecific mating between North American <i>Somatochlora</i> species as inferred from multi-gene phylogenies. We used mitochondrial genes (<i>COI</i> and <i>ND3</i>) and nuclear genes (<i>EF1-α</i> and <i>ITS2</i>) to construct phylogenies using maximum parsimony. Observation of non-monophyletic mtDNA lineages but monophyletic nDNA lineages between <i>Somatochlora</i> sister-species would indicate mtDNA introgression and suggest heterospecific matings. Our results highlighted three instances of non-monophyly of mtDNA clades in the following groups: (i) <i>S. hineana</i> + <i>S. tenebrosa</i>; (ii) <i>S. kennedyi</i> + <i>S. forcipata</i> + <i>S. franklini</i>; and (iii) <i>S. calverti</i> + <i>S. provocan</i>s + <i>S. filosa</i>. Analysis of partitioned Bremer support indicates that mtDNA <i>COI</i> largely contributed to the non-monophyly of these species, thus suggesting mtDNA introgression resulting from heterospecific matings. Additionally, the topology resulting from the combined data analysis was concordant with previous taxonomic understanding of <i>Somatochlora</i> species groups. These multi-gene phylogenies of North American <i>Somatochlora</i> are the first, providing a foundation for future ecological and evolution studies and knowledge for effective decision-making and public policy, which is especially important for the endangered species, <i>S. hineana</i>.</p>","PeriodicalId":50688,"journal":{"name":"Cladistics","volume":"40 6","pages":"598-617"},"PeriodicalIF":3.9,"publicationDate":"2024-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/cla.12599","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142512357","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Over the last 50 years, several methods have been proposed to reconstruct these histories. However, despite their particularities, conceptually they have been most often derived from the reconstruction of area relationships. Here we advocate that area cladograms lack explanatory power and that biogeography needs to move towards a more mechanistic approach. We discuss the ontological problems related to areas of endemism and their validity as biogeographic units. Specifically, we propose that areas of endemism are not discrete historical entities and that area-based analyses are inappropriate for analytical biogeography. Instead, we suggest that biogeographic analyses should focus on those spatial–geographic elements that cause diversification, namely barriers. We discuss how barriers have more discrete boundaries in space and time than do areas of endemism, which allows the identification of homologous units and the recovery of vicariant events. Reconstructing the history of vicariant events results in a better understanding of spatial evolution within a biota because barrier formation is the relevant causal mechanism of diversification.

With the rapid growth of species discovery and the perplexing morphology of male genitalia in the <i>Laufeia</i> clade, the controversy in its classification has become a crucial problem. In this study, we applied a phylogenomic approach using ultra-conserved elements data to infer the phylogeny of the <i>Laufeia</i> clade with extensive taxon sampling. A comparative morphological study was performed to evaluate diagnostic characters and understand the evolution of the male embolic complex within the <i>Laufeia</i> clade. The evolution of microhabitats (foliage, tree trunk, rock and surface litter) was also investigated to uncover the potential link between the microhabitat shifts and male embolic complex divergence. The results provide a strongly supported phylogenetic framework and updated generic concepts for the <i>Laufeia</i> clade. The synapomorphies for the updated genera within the <i>Laufeia</i> clade were identified through character mapping on the phylogeny. Ancestral state reconstruction analyses revealed that the Type I embolic complex (characterized by a disc-like embolic disc with a lamina as its outer edge) was ancestral and gradually evolved into the Type II (without lamina of embolic disc, base of embolic complex often modified into a functional “conductor”) and Type III (lacking lamina of embolic disc and base of embolic complex) embolic complex, and that some embolic shapes evolved multiple times independently in different lineages of the <i>Laufeia</i> clade. The shift from foliage-dwelling to tree trunk-dwelling in the common ancestor of the <i>Laufeia</i> clade may have facilitated the divergent evolution of male embolic complex in the <i>Laufeia</i> clade.

Dysderids are mostly restricted to the Western Palearctic, and particularly rich and abundant around the Mediterranean region. Interestingly, the distribution of species richness among its 24 genera and three subfamilies is highly biased—80% of its 644 documented species belong to just two genera, <i>Dysdera</i> (326) and <i>Harpactea</i> (211). Dysderidae provides an excellent study case for evolutionary and ecological research. It includes cases of trophic specialization, which are uncommon among spiders, and exhibit other remarkable biological (e.g. holocentric chromosomes), behavioural (e.g. cryptic female choice), evolutionary (e.g. adaptive radiation) and ecological features (e.g. recurrent colonization of the subterranean environment). The lack of a quantitative hypothesis on its phylogenetic structure has hampered its potential as a testing ground for evolutionary, biogeographical and ecological hypotheses. Here, we present the results of a target, multi-locus phylogenetic analysis, using mitochondrial (cox1, 16s and 12s) and nuclear genes (h3, 28s and 18s), of the most exhaustive taxonomic sample within Dysderidae (104 spp.) to date and across related families (Synspermiata) (83 spp.). We estimate divergence times using a combination of fossil and biogeographic node calibrations and use this timeline to identify shifts in diversification rates. Our results support the monophyly of the Dysderidae subfamilies Rhodinae and Dysderinae but reject Harpacteinae as currently defined. Moreover, the clades recovered within Harpacteinae do not support its current taxonomy. The origin of the family most likely post-dated the break-up of Pangea, and cave colonization may be older than previously considered. After correcting for the taxonomic artefacts, we identified a significant shift in diversification rates at the base of the genus <i>Dysdera</i>.

Urbacodon norelli is distinguished from all other known troodontids, including its relative U. itemirensis from Uzbekistan, by several features: the presence of paired dentary symphyseal foramina, the presence of a relatively steep anterior margin of the dentary, the absence of a dentary chin, the presence of a common groove hosting the anterior 12 dentary teeth, and the presence of relatively larger dentary teeth. Phylogenetic analysis places both species of Urbacodon as sister taxa to Zanabazar junior, confirming their status as later-diverging troodontids. Radiographs revealed an alternating tooth replacement pattern in U. norelli, with a maximum Zahnreihen-spacing estimated to be 3. During tooth replacement, the anteriorly inclined interdental septa, which wedge between anterior dentary teeth, underwent frequent remodelling as the developing tooth moved upwards, particularly anterolabially. This rapid turnover left insufficient time for an interdental plate to form, resulting in the absence of such structures in this specimen. The frequent remodelling of periodontal tissues accompanying tooth replacement is likely to account for the absence of interdental plates.
