In this study, we sequenced five genes (COI, COII, Cytb, 18S, and 28S) from a total of 46 gryllacridid individuals mainly from China. Subsequently, we utilized both the maximum likelihood method and the Bayesian inference method to construct a phylogenetic tree, aiming to elucidate the phylogenetic relationships within Gryllacrididae from China. Our results indicate that the genera Phryganogryllacris Karny, Capnogryllacris Karny, and Eugryllacris Karny are not monophyletic. Thus, we redescribe these genera, resurrect two genera (Marthogryllacris Karny stat. resurr. and Borneogryllacris Karny stat. resurr.), erect six new genera (Dracogryllacris gen. nov., Magnigryllacris gen. nov., Radigryllacris gen. nov., Sericgryllacris gen. nov., Bicornisgryllacris gen. nov., and Tenuigryllacris gen. nov.), and described two new species (Tenuigryllacris huanglianensis Li, Yin & He sp. nov. and Tenuigryllacris yingjiangensis Li, Yin & He sp. nov.).

Fossoriality reflects this functional association between morphology and the use of subterranean habitats and their associated environmental characteristics. Lizards in the families Gymnophthalmidae and Alopoglossidae are model organisms to examine the interplay between morphology and fossoriality because great morphological diversity exists among species, including varying degrees of body elongation and limb reduction, and they have a wide geographical distribution in the Neotropical region. We analysed the morphology of 101 microteiid species and created an index to evaluate their degree of fossoriality. From this index, we traced the evolution of fossoriality in these lizards and assessed its primary environmental correlates. We found that fossoriality evolved independently in several lineages, mainly associated with high temperature and low precipitation, characteristic of more arid and sandy environments.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":"70 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141764082","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}

Sengis’ low population densities and their distribution, which includes politically unstable regions with ongoing armed conflicts, hinder contemporary sampling of comprehensive datasets. We overcome this obstacle for the species Petrodromus tetradactylus, one of the most widely distributed sengi species, by utilizing 44 historical museum samples from multiple natural history museums. These historical samples were combined with newly generated or published data of 11 modern samples, thus creating a dataset of 55 P. tetradactylus individuals covering most of the species’ distribution. Phylogenetic reconstruction with 11 nuclear loci in conjunction with mostly complete mitochondrial genomes reveals multiple deeply divergent and formerly unknown lineages within this monotypic genus, highlighting the need for a taxonomic revision. Furthermore, we can show that the assumed allopatric distribution of P. tetradactylus in Central Africa most likely represents a sampling artifact. Biogeographic character mapping indicates that the African forest system and its dynamics through climate fluctuations shaped the evolutionary and biogeographic history of this taxon. We show that lineages within Petrodromus that were able to adapt to dryer woodland ecosystems are much more widely distributed than lineages restricted to moist forest systems. The evolution and radiation of the four-toed sengi (P. tetradactylus) mirrors the patterns of its distant relative, the giant sengis (Rhynchocyon) in both ecotype variation and overall distribution, implying a significant influence of climate and landscape features in shaping diversification.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":"67 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141725939","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}

Artemia is a model crustacean for population analysis and comparison in regionally endemic sexual species and parthenogenetic lineages distributed in hypersaline lakes, lagoons, and solar saltworks scattered in arid and semi-arid areas worldwide. The taxonomy of two American Artemia species has been controversial: Artemia monicaVerrill, 1869, adapted to the carbonate-rich conditions of Mono Lake (CA, USA), and Artemia franciscanaKellogg, 1906, a species broadly distributed in the Americas. The former species has been studied little, despite being listed as threatened in the IUCN Red List. In contrast, the latter has been studied extensively, is broadly distributed in the Americas, and has become established as a non-native invasive species in Europe, Asia, Africa, and Australia. Given the need to conserve A. monica, the intraspecific diversity of invasive A. franciscana, and the local species in areas invaded by this species, we reconsider their biodiversity and taxonomic status currently threatened by synonymization. In conclusion, A. monica and A. franciscana should be treated as two separate species that are isolated both ecologically and reproductively.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":"2 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141631549","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}

In this biomechanical work, we approach the hypothesis of the cartilaginous neutral pose and the range of motion of the axial series of Trigonosaurus. The results show that this sauropod could be capable of high elevation of the neck resulting from morphological adaptations of the cervicodorsal region on dorsal (D) vertebrae D2 and D3 (e.g. postzygapophyses of D2 positioned over the vertebral centrum and prezygapophyses of D3 over the anterior vertebral centrum). This implies that D2 articulates (cartilaginous neutral posture) with D3 only at a strong dorsally directed angle, resulting in a shift in the direction of the neck to a more elevated posture. Furthermore, the tail attributed to Trigonosaurus as a paratype could be oriented in the horizontal ‘direction’ and presented a sigmoidal ‘shape’. This work contributes generally to the understanding of variation in the body plan of sauropods and, more specifically, to the feeding strategy of small and medium-sized titanosaurs from semi-arid regions of Gondwana.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":"61 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141631551","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}

Alas, their origins remain a mystery. Here we describe three specimens from the Sinemurian (and possibly Early Pliensbachian) of the UK: a partial cranial rostrum, a series of cervical vertebrae, and two dorsal vertebrae adhered with matrix. These specimens are amongst the oldest known thalattosuchian fossils, with the partial cranial rostrum being the oldest known non-neothalattosuchian thalattosuchian. This partial cranial rostrum has a unique combination of rostral characters never seen before in any crocodylomorph, and helps to elucidate early thalattosuchian internal rostrum evolution, suggesting that the reduction in thalattosuchian paranasal sinuses was not related to either the reorganization of rostral neurovasculature seen in later diverging taxa or the increased cancellous bone microstructure. Based on our CT sample, a shift in cranial bone microstructure occurred in the Eoneustes + Metriorhynchidae subclade, one that coincided with the enlargement of the salt glands and decoupling of the external antorbital fenestra from the paranasal sinuses. Without extensive histological sampling we cannot determine whether the shift to an obligate aquatic lifestyle occurred prior to the evolution of Metriorhynchidae.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":"10 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141608160","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}

Only P. petronella was unchanged in both nomenclature and diagnostic characteristics with the remainder requiring alterations. Perhaps the most important of these was elevation of P. radiatella to a valid species, with its populations having been previously lumped either under European P. hammonis or North American P. electrina. Divergence times of 18.7–10.0 Mya were suggested through genome-wide SNPs in combination with the fossil record, indicating a pre-Pleistocene origin for all Perpolita species. Using genetically-confirmed diagnostic shell characters, we accumulated > 2000 valid occurrences and used these to estimate appropriate modern and Last Glacial Maximum climate extents for all species.

The phylogenetic analyses based on the gene COI support the morphologically based taxonomic assignment. The SR-PhC micro-CT was useful for viewing the three-dimensional reconstructions, with the great advantages that the specimen could be rotated around all axes and that it was possible digitally to remove sections of the image that might have obscured areas of the amphipod on which we were focusing. However, it is not yet a completely reliable technique to describe a new species fully. Classical descriptions using light microscopy and scanning electron microscopy are still necessary.

The class Litostomatea is a morphologically diverse ciliate group that comprises hundreds of free-living and endosymbiotic species. Here, we sequenced 14 predatory litostomateans, i.e. 12 haptorians and two rhynchostomatians. A comparative analysis was performed with other published omics’ data on litostomateans. Our first phylogenomic analysis of litostomateans showed the monophyly of the subclasses Trichostomatia and Rhynchostomatia, the non-monophyly of the subclass Haptoria, and the monophyly of all orders and families that were analysed. Evolutionary history analysis suggested that Litostomatea diverged during the Late Neoproterozoic, the family Chaeneidae was the earliest diverging haptorian lineage, and the Rhynchostomatia probably separated from the order Lacrymariida (subclass Haptoria) during the Early Palaeozoic. Stop codon usage analysis of 28 litostomateans showed that they use TAA as the biased stop codon and reassign the other two stop codons (TAG and TGA) to code for amino acids. In addition, the preferred codons in the 14 newly sequenced litostomateans are strongly biased towards A/U bases in the third position, very probably due to the comparatively low GC content. Genes encoding carbohydrate-active enzymes (CAZymes) are more diversified in the endosymbiotic Trichostomatia than in the free-living predatory Rhynchostomatia and Haptoria, suggesting that trichostomes have the strongest capability of carbohydrate utilization. Notably, we found that three free-living litostomateans (Didinium sp.1, Myriokaryon sp., and Apodileptus visscheri) exhibit substantial differences from other free-living ciliates in terms of their number of CAZymes. Considering the potency and versatility of CAZymes in the degradation and biotransformation of carbohydates, we propose that the multifarious CAZymes in these three ciliates could be a survival strategy for nutrient acquisition and niche adaptation. Finally, the functional annotation of significantly expanded gene families in these three ciliates revealed their vigorous potency in biochemical metabolism. These findings will facilitate wider omic-scale phylogenetic analyses of Litostomatea and deepen our understanding of this group from an evolutionary standpoint.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":"24 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141489517","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}
