The subfamily Gonideinae of freshwater mussels is currently thought to include eight tribes. However, due to inadequate taxon sampling and molecular data, the assignment of the freshwater mussel genus <i>Inversidens</i> at the tribe level has been unstable. Additionally, the lack of phylogenetic data has hindered efforts to understand the basic biology and implementation of conservation efforts of <i>Inversidens rentianensis</i>, an endemic species to China. Here, we first present the complete mitochondrial genome of <i>Inversidens rentianensis</i> and offer a detailed description of its anatomical morphology. Based on DNA sequence data from five genes (COI, ND1, 16S rRNA, 18S rRNA, and 28S rRNA) and complete mitochondrial genomes, we investigated the phylogenetic position of <i>Inversidens</i> using various analytical methods. Both the concatenated five-gene and mitogenome datasets strongly supported that <i>Inversidens</i> classified to the tribe Gonideini in Gonideinae and formed a basal clade within the tribe Gonideini. Molecular dating analysis suggested that <i>Inversidens</i> originated during the mid-Cretaceous era (102.73 Mya, 95% highest posterior density (HPD) = 72.22-137.03 Mya) and underwent diversification in the Late Paleogene era (37.92 Mya, 95% HPD = 20.39-60.59 Mya). Moreover, based on the Quantitative Assessment of Species for Conservation (QASCP), <i>Inversidens rentianensis</i> is ranked as second priority, providing valuable insights for its management and conservation efforts. Taken together, this study provides a comprehensive understanding of the systematic position and evolutionary history of <i>Inversidens</i> within the currently accepted subfamily Gonideinae classification framework. These findings establish a solid foundation for future investigations on the ecology, reproductive behavior patterns, and conservation biology of this taxonomic group.</p>\u0000 </div>","PeriodicalId":54751,"journal":{"name":"Journal of Zoological Systematics and Evolutionary Research","volume":"2024 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/2024/1499508","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139397015","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}

The most dominant species of the Trimmu barrage were the common pochard, little grebe, common coot, cattle egret, gadwall, little egret, red-wattled lapwing, and common teal. On the other hand, the Indian roller, common quail, cattle egret, common myna, and Indian kite were found to be the most common species in the Thal desert.

Zinc finger proteins are a type of transcription factor that plays a role in regulating gene expression, particularly in undifferentiated stem cells. Suppose it has been found that certain zinc finger proteins show genetic signatures of positive selection in mammals. In that case, it suggests that these proteins may have played a role in adaptive evolution in undifferentiated stem cells. This could mean that the specific genetic changes in these zinc finger proteins gave an advantage to the organisms that possessed them, helping them survive and reproduce more effectively. These genetic changes may have allowed the organisms to adapt to changing environments or to develop new abilities, such as increased resistance to disease or faster growth. Undifferentiated stem cells that underwent adaptive evolution during the evolution of mammals can be identified genetically by the outcomes of positive selection on zinc finger proteins. Because of selection pressures like environmental shifts or the introduction of novel pathogens, it is plausible that some zinc finger proteins have experienced fast evolution. The emergence of novel activities or higher expression levels of these proteins as a result of this quick evolution may have given the creatures that possessed them a survival edge. Another possible outcome of positive selection in zinc finger proteins is the emergence of new genetic variations that allow for increased diversity and plasticity in stem cells. This increased diversity and plasticity could have allowed for more efficient adaptation to changing environments and could have played a role in the evolution of new organisms or new characteristics in existing organisms. Overall, the results of positive selection in zinc finger proteins can provide insight into how adaptive evolution occurred in undifferentiated stem cells during the evolution of mammals and how this evolution may have contributed to the development of new organisms and new characteristics and adaptations to changing environments.</p>\u0000 </div>","PeriodicalId":54751,"journal":{"name":"Journal of Zoological Systematics and Evolutionary Research","volume":"2023 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2023-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/2023/6693488","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49370756","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}

However, the phenotypic variability of <i>Cheilosia soror</i> (Zetterstedt, 1843), a highly variable member of the <i>C. longula</i> group, has never been assessed in western Europe. In the present work, morphological and molecular analyses were conducted to assess the phenotypic variability found in 300+ specimens of <i>C. soror</i> from the Iberian Peninsula. A total of 16 variable characters were identified and defined for the <i>C. soror</i> morphology, with the highest variation found in the colour of the mesonotum pilosity and the metatibia colour. Morphological variation was assessed against molecular variation based on two molecular markers, one mitochondrial, the 5′ end of the cytochrome c oxidase subunit I (COI-5′), and one nuclear, the large subunit ribosomal DNA (28S). Phylogenetic analyses rendered trees with topologies in disagreement with the defined morphological variation. Two haplotypes were identified amongst the analysed specimens of <i>C. soror</i>, together with a haplotypic variant exclusive to the Iberian region. Potential distributions were used to identify unexplored areas of occurrence of <i>C. soror</i> and other species of the <i>C. longula</i> group in the Iberian Peninsula. Unassessed areas of occurrence of <i>C. soror</i> should be surveyed in the future to confirm the absence of hidden taxonomic diversity within the range of phenotypic variation for this species. Phenotypic variation of the other two Iberian species of the <i>C. longula</i> group, <i>C. longula</i> and <i>C. scutellata</i> (Fallén, 1817), was also assessed to find that they are species with less-variable morphology than <i>C. soror</i> and with molecular characters in accordance with other conspecific populations in Europe. New distributional data are provided for <i>C. soror</i> and <i>C. scutellata</i> from Spain, and a leg abnormality is identified for the first time in <i>C. soror</i>.</p>\u0000 </div>","PeriodicalId":54751,"journal":{"name":"Journal of Zoological Systematics and Evolutionary Research","volume":"2022 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2022-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/2022/8378483","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43010809","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}
