The fossil record is of little help because the remains of extant taxa are relatively recent, and only three extinct species, of uncertain relationships, have been described so far. An Early Pliocene extinct species of the currently monotypic genus Chersina, still inhabiting South Africa, was reported at the fossil-rich site of Langebaanweg more than 50 years ago but never formally described. Here we erect and describe the extinct species Chersina langebaanwegi sp. nov. on the basis of abundant material that provides information on its morphological variation. The referral of the new species to the genus Chersina is supported by phylogenetic analysis which includes the Malagasy ploughshare tortoise, sharing the presence of a single gular shield covering a very long gular protrusion with Chersina spp. and a domed shell with C. langebaanwegi sp. nov. The material from Langebaanweg represents the oldest fossil evidence of this genus. It significantly post-dates the branching of Chersina from its sister taxon Chersobius, but pre-dates the presumed split of the extant lineages of Chersina angulata as estimated on molecular basis.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":"32 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142637637","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, little is known about the relationships between fossils assigned to Clupei, particularly those that are demonstrably related to extant herring-like members of the order Clupeiformes. To help bridge this gap, we present a new morphological phylogeny that includes representatives of all major clupeiform lineages. The data matrix consists of 192 characters, drawn from 79 extant and 37 fossil taxa and selected to be readily identifiable in fossils. Most clupeiform families are recovered as monophyletic, and their interrelationships are generally compatible with previous morphological hypotheses. The phylogenetic positions of six fossil clupeiform taxa are resolved, as the results of all analyses (unconstrained/constrained parsimony and Bayesian inference) are consistent. Twenty-one fossil taxa are incertae sedis, including two species of Ellimmichtyiformes, which are recovered as Clupeoidei in the parsimony analyses. The relationships of the rest of the fossils are interpreted with varying degrees of certainty. The evolution of key morphological characters is discussed in light of the new results, and four fossil taxa are proposed as calibration points for future dating studies.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":"2 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142597786","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Comparative analysis of the evolution of soft-tissue structures in the fish skull is often limited under traditional approaches, while new imaging techniques like diceCT (diffusible iodine-based contrast-enhanced computed tomography) allow for high-resolution imaging of muscles in situ. Darters (Percidae: Etheostomatinae) are a diminutive and species-rich clade of lotic freshwater fishes, which show diverse head shapes believed to be associated with different foraging strategies. We used diceCT to sample all major cranial adductors and abductors responsible for movement of the jaw, hyoid, operculum, and suspensorium from 29 species. We applied comparative phylogenetic approaches to analyse the evolutionary trends in muscle size across the clade. We found two major patterns: (i) darter cranial muscles show fundamental trade-offs relating to investment in musculature, as well as buccal expansion vs. biting attributes; early divergence in muscle size appears to be associated with shifts in habitat use and foraging; (ii) darter adductor mandibulae show high variation in architecture (fibre orientation, divisions).

Herein, the taxonomy of Synodontis in the Lake Tanganyika basin is revised, including redescriptions of all species and an updated identification key.

However, the conspecific diversity and evolutionary history of these species are not yet well understood. In this study, therefore, we used mitochondrial COI and nuclear ITS1-2 sequences to perform species delimitation tests, and demographic and phylogeographic analyses to understand candidate species and evolutionary history of the seven species. While our results did not support the species status of S. balcanicum, S. turgaicum, and S. lineatum, it did suggest several candidate species within S. equinum and S. pseudequinum. Molecular clock analysis revealed that significant branching events occurred in the Pliocene, and demographic fluctuations in the populations occurred intensely during the Pleistocene. Overall, the results indicated that Anatolia has served as a significant refugium for ancestral haplotypes, and it is an important dispersal corridor between the eastern and western Palearctic for Wilhelmia species.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":"87 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142563094","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our work also elucidates the very recent radiation of Bythotrephes, which may have begun rapidly and parallel during the Late Pleistocene, or even after the last glaciation. Finally, we provide a comprehensive biogeographic reconstruction of Bythotrephes dispersal within the Holarctic realm.

We estimated diversification rates, ancestral areas, and ancestral habitats for each node. Findings were interpreted within a detailed biogeographical synthesis. The results indicate that the clade arose in the Eocene along the Gulf of México coast. The speciation rate was uniform through time, except for acceleration in Cyprinodontidae after ~10.9 Mya. In other families, neither viviparity nor marine-to-freshwater transition was associated with accelerated speciation. Sea-level fluctuations might have created a speciation pump by stimulating cycles of dispersal and vicariance along the coast. Diversification also included many cases of inland immigration from coastal ancestors. For upland lineages, ancient river drainages accord with lineage distributions, including enigmatic disjunctions in Goodeidae and Fundulus. Diversification in uplands occurred via barrier displacement within alluvial or tectonically active landscapes. Killifishes also display high environmental tolerance and persist within harsh, peripheral environments unsuitable for most other fishes. Hence, a combination of clade antiquity, adaptability, dynamic geography, and persistence can explain the living diversity of New World killifishes.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":"34 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142490403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
