Here, we review the current solifuge literature through the lens of conceptual research areas in ecology, evolution, and behaviour and propose ways in which solifuges can contribute to research in specific subfields, as follows: (i) ecology: community and trophic dynamics; connecting food webs; habitat specialization; and biodiversity and conservation; (ii) evolution: speciation and diversification; activity cycles and associated traits; adaptations for speed; and living in extreme environments; and (iii) behaviour and sensory systems: sleep, quiescence, and diapause; sensory systems and sensory ecology; learning and cognition; and mating systems, sexual selection, and sexual conflict. This resource can provide a starting point for identifying research programmes that will simultaneously contribute basic natural history information about this under-studied group and provide a broader understanding of fundamental concepts and theories across the life sciences. We hope that scientists will take this review as a challenge to develop creative ways of leveraging the unique features of solifuges to advance scientific knowledge and understanding.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2023-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139060854","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}

Parsimonious morphological assessments divided the single superfamily Pleurobranchoidea into the shell-less Pleurobranchaeidae and the internally shelled Pleurobranchidae, including the aberrant helicoid-shelled Tomthompsonia. Molecular evidence has proven untrustworthy to date, revealing contrasting hypotheses. This study’s multilocus phylogeny benefits from a dense taxon sampling of 94 pleurobranchids, with 22 newly sequenced specimens, including type species for all known genera. We further evaluate the effects of masking with several algorithms to better enhance phylogenetic resolution. Our results support that Tomthompsonioidea superfam. nov. are the sister group of all other Pleurobranchida; the absence of an acidic oral gland and a helicoid shell are the diagnostic features. We also provide the first molecular evidence that Euselenops nests within Pleurobranchaeidae, and Pleurobranchella is related to Pleurobranchaea, but remains distinct morphologically. Regarding Pleurobranchidae, the genus Berthella is paraphyletic and now embodied in the four clades: Berthella s.s., Boreoberthella, Pleurehdera, and Tomoberthella gen. nov. The fact that, whereas there is a supposed low Antarctic diversity, we find hidden speciation in several tropical species suggests that side-gilled slugs pose an Antarctic origin or a relic that radiated in shallower, warmer waters.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2023-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139041472","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}

The subgenus is represented by two morphological species, both endemic to the Pyrenees and their southern foothills. We conducted phylogenetic analyses based on mitochondrial and nuclear gene fragments of topotypes and other populations, four molecular species delimitation methods, and morphological examinations to clarify the uncertain systematic position of the subgenus within the family, assess its species diversity, and understand the population genetic structure of the two geographically restricted species. Our phylogenetic results revealed that Alzoniella (Navarriella) is distantly related to all other species of Alzoniella, even belonging to an independent subfamily-level clade, for which we introduce the new genus Navarriella and the new subfamily Navarriellinae subfam. nov. Molecular methods and geometric morphometric analysis of shell shape identified a single species in the new genus. The significant phylogenetic distance from other hydrobiid taxa, narrow distribution, and limited gene flow among its populations (estimated from mitochondrial cytochrome c oxidase subunit I sequences) highlight Navarriella as an isolated lineage within the family that requires urgent conservation attention. Furthermore, our results cast a new light on the northern Iberian Mountains as a dispersal barrier for ancient spring lineages.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2023-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139041490","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}

From an evolutionary perspective, parthenogenesis seems less successful than the predominant sexual mode, though there are groups in which both reproductive types exist, an example of which is the genus Artemia Leach, 1819. This salt-tolerant crustacean inhabiting hypersaline environments contains regionally endemic sexual species and obligate parthenogenetic groups with different ploidy levels, collectively referred to as Artemia parthenogenetica. Here, we discuss the difficulties of using a common species concept in Artemia Leach, 1819. While sexual species are widespread and fit the Biological Species Concept (BSC), which emphasizes reproductive isolation to maintain species genetic integrity or cohesiveness, it does not apply to uniparental organisms originating from sexual species with major meiotic changes. We show that different ploidy levels of parthenogenetic Artemia groups with uniform nuclear gene pools are maternally independent genetic entities (or cohesive), collectively and wrongly referred to as Artemia parthenogenetica. Thus, we conclude that ‘Artemia parthenogenetica’ is an invalid nominal specific name. Additionally, parthenogenetic Artemia groups cannot be considered a form of Artemia species (A. urmiana and/or A. sinica). In conclusion, we recommend using the term ‘parthenogenetic lineage(s)’ instead of ‘parthenogenetic population(s)’ to describe asexual Artemia group(s), because in modern population genetics and systematics, the term ‘population’ refers to interbreeding individuals with sexual reproduction. Furthermore, it clarifies that parthenogenetic lineages of Artemia are native to Mediterranean biodiversity.","PeriodicalId":49333,"journal":{"name":"Zoological Journal of the Linnean Society","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2023-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139041430","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}
