  • Protura from hainan island china new species checklist and distribution
    ZooKeys, 2019
    Co-Authors: Yan Xiong, Yun-xia Luan, Wen-ying Yin
    Abstract:

    More than 1500 Proturan specimens from Hainan Island are systematically studied. An annotated list of all species of Protura from Hainan Island is provided and their geographical distribution is discussed. The genus Paracondeellum is reported from Hainan Island for the first time, and Paracondeellum paradisum sp. nov. is described. The type species Paracondeellum dukouense (Tang & Yin, 1988) is redescribed based on syntype, and the lectotype and paralectotype are designated. The characters of the genus Paracondeellum are redefined, and the two known species are compared in detail. The Protura fauna of Hainan Island is mainly composed of species from the Oriental region, with 91% of the species belonging to the families Berberentulidae and Eosentomidae.

  • systematic and biogeographical study of Protura hexapoda in russian far east new data on high endemism of the group
    ZooKeys, 2014
    Co-Authors: Mikhail Potapov, Wen-ying Yin
    Abstract:

    Proturan collections from Magadan Oblast, Khabarovsk Krai, Primorsky Krai, and Sakhalin Oblast are reported here. Twenty-five species are found of which 13 species are new records for Russian Far East which enrich the knowledge of Protura known for this area. Three new species Baculentulus krabbensis sp. n., Fjellbergella lazovskiensis sp. n. and Yichunentulus alpatovi sp. n. are illustrated and described. The new materials of Imadateiella sharovi (Martynova, 1977) are studied and described in details. Two new combinations, Yichunentulus borealis (Nakamura, 2004), comb. n. and Fjellbergella jilinensis (Wu & Yin, 2007), comb. n. are proposed as a result of morphological examination. Keys to species of the genera Fjellbergella and Yichunentulus are given. An annotated list of all species of Protura from Russian Far East is provided and discussed. Widely distributed species were not recorded in this area. This may be because of the high sensitivity of Protura to anthropogenic impact and low dispersal ability of the group.

  • new nipponentomon species from northern asia Protura acerentomata nipponentomidae
    Zootaxa, 2013
    Co-Authors: Julia Shrubovych, Wen-ying Yin
    Abstract:

    Nipponentomon imadatei sp. nov. from Northeast China and Nipponentomon taiga sp. nov. from Siberia, Russia are de-scribed. Nipponentomon heterothrixi Yin & Xie is redescribed based on type materials and lectotype and paralectotypes are designed for the species. Nipponentomon bidentatum and N. nippon are reported for the first time from China. Nippo-nentomon imadatei sp. nov. is characterized by a short labrum, absence of seta P1a on tergite VII and presence of three A -setae on sternites IV–VI. It is similar to N. jaceki from the Russian Far East, but differs in the shape of the comb, shape of seta β 1 on the foretarsus, length of sensillum e on the foretarsus, and in chaetotaxy on tergite I and sternites IV–VI. Nipponentomon taiga sp. nov. is characterized by a short labrum, presence of seta P2a' on nota, seta P0a on tergite I, seta P1a on tergites I–VII, and absence of seta P3a on tergites II–VII. It is similar to N. heterothrixi , but differs in absence of seta d6 on the head, shape of accessory setae on tergites VI and VII, long and setiform seta β 1 , and shorter sensilla c , e , g , a' and c' on the foretarsus than in sensilla in N. heterothrixi and in the porotaxy. A key for the world species of the genus is provided and the porotaxy of five species is reported in detail.

  • The mitochondrial genome of Sinentomon erythranum (Arthropoda: Hexapoda: Protura): an example of highly divergent evolution.
    BMC evolutionary biology, 2011
    Co-Authors: Wan-jun Chen, Antonio Carapelli, Romano Dallai, Wen-ying Yin, Yun-xia Luan
    Abstract:

    The phylogenetic position of the Protura, traditionally considered the most basal hexapod group, is disputed because it has many unique morphological characters compared with other hexapods. Although mitochondrial genome information has been used extensively in phylogenetic studies, such information is not available for the Protura. This has impeded phylogenetic studies on this taxon, as well as the evolution of the arthropod mitochondrial genome. In this study, the mitochondrial genome of Sinentomon erythranum was sequenced, as the first Proturan species to be reported. The genome contains a number of special features that differ from those of other hexapods and arthropods. As a very small arthropod mitochondrial genome, its 14,491 nucleotides encode 37 typical mitochondrial genes. Compared with other metazoan mtDNA, it has the most biased nucleotide composition with T = 52.4%, an extreme and reversed AT-skew of -0.351 and a GC-skew of 0.350. Two tandemly repeated regions occur in the A+T-rich region, and both could form stable stem-loop structures. Eighteen of the 22 tRNAs are greatly reduced in size with truncated secondary structures. The gene order is novel among available arthropod mitochondrial genomes. Rearrangements have involved in not only small tRNA genes, but also PCGs (protein-coding genes) and ribosome RNA genes. A large block of genes has experienced inversion and another nearby block has been reshuffled, which can be explained by the tandem duplication and random loss model. The most remarkable finding is that trnL2(UUR) is not located between cox1 and cox2 as observed in most hexapod and crustacean groups, but is between rrnL and nad1 as in the ancestral arthropod ground pattern. The "cox1-cox2" pattern was further confirmed in three more representative Proturan species. The phylogenetic analyses based on the amino acid sequences of 13 mitochondrial PCGs suggest S. erythranum failed to group with other hexapod groups. The mitochondrial genome of S. erythranum shows many different features from other hexapod and arthropod mitochondrial genomes. It underwent highly divergent evolution. The "cox1-cox2" pattern probably represents the ancestral state for all Proturan mitogenomes, and suggests a long evolutionary history for the Protura.

  • two new species of genus hesperentomon price 1960 Protura hesperentomidae from northern china
    Zootaxa, 2011
    Co-Authors: Julia Shrubovych, Wen-ying Yin
    Abstract:

    Two new species of Hesperentomidae are described from northern China. Hesperentomon fopingense sp. nov. is characterized by 16 P-setae on urotergites II–VI, long, slender foretarsal sensilla t-1 and t-2 and a round flap on the inner side of the acrostylus of the female squama genitalis. Hesperentomon dunhuaense sp. nov. is characterized by 12 P-setae on urotergites II–VI, short, slender foretarsal sensilla t-1 and t-2 and a slender flap on outer side of the acrostylus of the female squama genitalis.

  • responses of soil microarthropod taxon hexapoda Protura to natural disturbances and management practices in forest dominated subalpine lake catchment areas
    Scientific Reports, 2020
    Co-Authors: Maria Sterzynska, Julia Shrubovych, Karel Tajovský, Peter Cuchta, Josef Starý, Jiři Kaňa, Jerzy Smykla
    Abstract:

    Disturbances are intrinsic drivers of structure and function in ecosystems, hence predicting their effects in forest ecosystems is essential for forest conservation and/or management practices. Yet, knowledge regarding belowground impacts of disturbance events still remains little understood and can greatly vary by taxonomic and functional identity, disturbance type and local environmental conditions. To address this gap in knowledge, we conducted a survey of soil-dwelling Protura, across forests subjected to different disturbance regimes (i.e. windstorms, insect pest outbreaks and clear-cut logging). We expected that the soil Proturan assemblages would differ among disturbance regimes. We also hypothesized that these differences would be driven primarily by variation in soil physicochemical properties thus the impacts of forest disturbances would be indirect and related to changes in food resources. To verify that sampling included two geographically distant subalpine glacial lake catchments that differed in underlying geology, each having four different types of forest disturbance, i.e. control, bark beetle outbreak (BB), windthrow + BB (wind + BB) and clear-cut. As expected, forest disturbance had negative effects on Proturan diversity and abundance, with multiple disturbances having the greatest impacts. However, differences in edaphic factors constituted a stronger driver of variability in distribution and abundance of Proturans assemblages. These results imply that soil biogeochemistry and resource availability can have much stronger effects on Proturan assemblages than forest disturbances.

  • Protura in arctic regions with description of mastodonentomon n gen acerentomidae nipponentominae and a key to known arctic taxa
    Insects, 2020
    Co-Authors: Julia Shrubovych, Jerzy Smykla, Ernest C. Bernard
    Abstract:

    Protura are widespread, but their presence in the Arctic was first noted only ca. 70 years ago and is still little acknowledged. This work compiles taxonomic information on Proturans in the Arctic regions and adds unpublished data from Northern Siberia. Currently, this fauna is represented by 23 species in two orders and 14 genera. The large cosmopolitan genus Eosentomon is represented by only four species, whereas Acerentomidae is much more diverse, with 19 species in 13 genera (eight Nipponentominae, five Acerentominae). Most of the Arctic species possess a larger number of setae than species living in temperate regions. Based on several unique characters, a new genus, Mastodonentomon, is erected for Nipponentomon macleani, and the species is re-described with the original description supplemented with new characters, including head chaetotaxy, seta length, and porotaxy. Proturan occurrence in the Arctic is limited to Beringia, but the majority of species have restricted distributions and none have been found in both the American Arctic and Siberia. This implies relict origins and high levels of Proturan endemism in the Arctic. This emerging view on biogeographical history is, however, hampered by the limited extent of available data, which highlights the need for considerably greater survey efforts. A key to Arctic Proturans is provided to facilitate further studies.

  • Protura are unique: first evidence of specialized feeding on ectomycorrhizal fungi in soil invertebrates.
    BMC ecology, 2019
    Co-Authors: Sarah L. Bluhm, Anton M. Potapov, Julia Shrubovych, Silke Ammerschubert, Andrea Polle, Stefan Scheu
    Abstract:

    Ectomycorrhizal fungi (ECM) play a central role in nutrient cycling in boreal and temperate forests, but their role in the soil food web remains little understood. One of the groups assumed to live as specialised mycorrhizal feeders are Protura, but experimental and field evidence is lacking. We used a combination of three methods to test if Protura are specialized mycorrhizal feeders and compared their trophic niche with other soil invertebrates. Using pulse labelling of young beech and ash seedlings we analysed the incorporation of 13C and 15N into Acerentomon gallicum. In addition, individuals of Protura from temperate forests were collected for the analysis of neutral lipid fatty acids and natural variations in stable isotope ratios. Pulse labelling showed rapid incorporation of root-derived 13C, but no incorporation of root-derived 15N into A. gallicum. The transfer of 13C from lateral roots to ectomycorrhizal root tips was high, while it was low for 15N. Neutral lipid fatty acid (NLFA) analysis showed high amounts of bacterial marker (16:1ω7) and plant marker (16:0 and 18:1ω9) fatty acids but not of the fungal membrane lipid 18:2ω6,9 in A. gallicum. Natural variations in stable isotope ratios in Protura from a number of temperate forests were distinct from those of the great majority of other soil invertebrates, but remarkably similar to those of sporocarps of ECM fungi. Using three in situ methods, stable isotope labelling, neutral lipid fatty acid analysis and natural variations of stable isotope ratios, we showed that Protura predominantly feed on mycorrhizal hyphae via sucking up hyphal cytoplasm. Predominant feeding on ectomycorrhizal mycelia by Protura is an exception; the limited consumption of ECM by other soil invertebrates may contribute to carbon sequestration in temperate and boreal forests.

  • distribution of Protura along an urban gradient in vienna
    Pedobiologia, 2004
    Co-Authors: Erhard Christian, A Szeptycki
    Abstract:

    Summary In the first study of the Protura of a big city, six representative habitat types were sampled in Vienna, Austria. Twenty-five sites between the green belt and the city centre yielded 42 known species. Abundance, species number and diversity were highest in colline deciduous forests, with a maximum of 23 syntopic species in a Quercus pubescens stand. Acerella muscorum , all of the five Acerentomon spp. and 13 further species occurred exclusively in colline deciduous forests. The mediterranean Berberentulus berberus and six other species were recorded exclusively in parks or artificial habitats, suggesting anthropogenic transport. No Protura were found in garden and arable soils. Species density in the municipal area of Vienna (415 km 2 ) is a function of the city's biogeographic situation on the border between the Alps and the Pannonian lowland as well as its diversity of seminatural habitats, and unintentional introduction.

  • The mitochondrial genome of Sinentomon erythranum (Arthropoda: Hexapoda: Protura): an example of highly divergent evolution.

  • spermatogenesis and sperm structure of acerella muscorum ionescu 1930 hexapoda Protura
    Tissue & Cell, 2010
    Co-Authors: Romano Dallai, David Mercati, Y W Yin
    Abstract:

    The general organization of the male genital system, the spermatogenesis and the sperm structure of the Proturan Acerella muscorum have been described. At the apex of testis apical huge cells are present; their cytoplasm contains a conventional centriole, a large amount of dense material and several less electron-dense masses surrounded by mitochondria. Spermatocytes have normal centrioles and are interconnected by cytoplasmic bridges. Such bridges seem to be absent between spermatid cells and justify the lack of synchronization of cell maturation. Spermatids are almost globular cells with a spheroidal nucleus and a large mass of dense material corresponding to the centriole adjunct. Within this mass a centriole is preserved. Mitochondria of normal structure are located between the nucleus and the plasma membrane. The spermatids are surrounded by a thick membrane. No flagellar structure is formed. Sperm have a compact spheroidal nucleus, a large cap of centriole adjunct material within which a centriole is still visible. A layer of mitochondria is located over the nucleus. The cytoplasm is reduced in comparison to spermatids; many dense bodies are interspersed with sperm in the testicular lumen. The sperm are small, immotile cells of about 2.5-3microm in diameter.

  • the spermatogenesis and sperm structure of acerentomon microrhinus Protura hexapoda with considerations on the phylogenetic position of the taxon
    Zoomorphology, 2010
    Co-Authors: Romano Dallai, David Mercati, Y W Yin, Giuliano Callaini, Maria Giovanna Riparbelli
    Abstract:

    The spermatogenesis of the Proturan Acerentomon microrhinus Berlese, (Redia 6:1–182, 1909) is described for the first time with the aim of comparing the ultrastructure of the flagellated sperm of members of this taxon with that of the supposedly related group, Collembola. The apical region of testes consists of a series of large cells with giant polymorphic nuclei and several centrosomes with 14 microtubule doublets, whose origin is likely a template of a conventional 9-doublet centriole. Beneath this region, there are spermatogonial cells, whose centrosome has two centrioles, both with 14 microtubule doublets; the daughter centriole of the pair has an axial cylinder. Slender parietal cells in the testes have centrioles with nine doublet microtubules. Spermatocytes produce short primary cilia with 14 microtubule doublets. Spermatids have a single basal body with 14 microtubule doublets. Anteriorly, a conical dense material is present, surrounded by a microtubular basket, which can be seen by using an α-anti-tubulin antibody. Behind this region, the basal body expresses a long axoneme of 14 microtubule doublets with only inner arms. An acrosome is lacking. The nucleus is twisted around the apical conical dense structure and the axoneme; this coiling seems to be due to the rotation of the axoneme on its longitudinal axis. The posterior part of the axoneme forms three turns within the spermatid cytoplasm. Few unchanged mitochondria are scattered in the cytoplasm. Sperm consist of encysted, globular cells that descend along the deferent duct lumen. Some of them are engulfed by the epithelial cells, which thus have a spermiophagic activity. Sperm placed in a proper medium extend their flagellar axonemes and start beating. Protura sperm structure is quite different from that of Collembola sperm; and on the basis of sperm characters, a close relationship between the two taxa is not supported.

  • tracheal ultrastructure of Protura insecta apterygota
    International Journal of Insect Morphology & Embryology, 1993
    Co-Authors: Luzheng Xue, Romano Dallai, Wen-ying Yin
    Abstract:

    The tracheal systems of Sinentomon and Eosentomon (Apterygota : Protura) were examined in thin sections and compared with the tracheae of collembolan, Allacma. The tracheal system of Protura consists of spiracles and tracheae. The spiracle is a simple, concave cuticular cavity known as an atrium. A globular chamber is present between the atrium and trachea. The atrium of Eosentomon is decorated with ridges and has 2 small openings to tracheal recesses beside the central tracheal opening. The tracheae of Protura are characterized by a high frequency of taenidia and the absence of intima folds and intertaenidial spaces. The taenidia of Sinentomon have a rectangular section and those of Eosentomon are gable-shaped. The results also suggest that the tracheal recess of Eosentomon is a kind of stigmatic gland. The tracheal structure of Protura was compared with that of collembolans, insects, and other arthropods, and discussed in terms of phylogeny. © 1993.

  • cephalic anatomy of sinentomon erythranum yin Protura sinentomidae
    International Journal of Insect Morphology & Embryology, 1992
    Co-Authors: Jean Francois, Romano Dallai, Wen-ying Yin
    Abstract:

    Abstract The structure of the head capsule, endoskeletal structures, oral folds, mouthparts, foregut, maxillary and labial glands, and the central nervous system of the Chinese Proturan Sinentomon erythranum Yin (Protura : Sinentomidae) have been described. The most significant features are the unusual thickness of the cuticle with numerous serrated lines, the reduction of sutures and the absence of linea ventralis, the simplification of gnathal pieces, and the reduction of the musculature. A comparison with other Protura and Apterygota leads to some morphological and phylogenetical interpretations of the cephalic structures, in particular those concerning the entotrophy.

  • the geographic distribution of Protura arthropoda hexapoda a review
    Biogeographia – The Journal of Integrative Biogeography, 2019
    Co-Authors: Loris Galli, Ivano Rellini
    Abstract:

    Author(s): Galli, Loris; Rellini, Ivano | Abstract: Protura is a poorly known class of Hexapoda represented by more than 800 species belonging to 77 genera worldwide. They are tiny soil organisms with low dispersal ability, mainly attributable to water and human-mediated transfer. The analysis of biogeography of Protura is hindered by the lack of knowledge on their natural history, systematics and distribution. In order to provide a starting point for future more detailed investigations, we reviewed the available literature on their geographic distribution, making a distinction between continental and insular areas. A general overview based on Wallace’s biogeographic regionalization is outlined, highlighting a maximum of known richness and endemism at the genus level in the Palearctic region, and particularly within its eastern part. Some detailed examples of disjunct distribution and their interpretation based on vicariance or dispersal events are given.

  • Immunohistochemical and lectin-based approach to Acerentomon sp. anatomy (Protura: Acerentomidae).
    2015
    Co-Authors: Sara Ferrando, Loris Galli, Lorenzo Gallus
    Abstract:

    The present study describes for the first time in Acerentomon sp. the distribution of glutamate decarboxylase-like immunoreactivity. The presence of this GABA-synthetizing enzyme was described in: pharynx wall, cephalic muscles, posterior part of the supraesophageal ganglion, abdominal glands, neuropil near to the posterior ganglion, cuticular muscle insertion and in sensilla. Furthermore the use of fluorochrome-conjugated lectins was tested in order to visualize taxonomic features (like pores and setae) on whole mount fixed Protura specimens. The development of a lectin-based technique could render more precise the species determination, allowing a more accurate identification
