It has three macroplacoids and microplacoid; claws short and stout; hind legs with basal margin indented; inter- nal and external claws on the first three pairs of legs almost of the same length; anterior claws on the hind legs longer than the posterior claws. Key words: Tardigrada, Hypsibiidae, Diphascon (Diphascon) dolomiticum sp. n., Italy Introduction In a moss sample collected in Passo del Grostè (Trento) two specimens of Hypsibiidae (Eutardigrada) were found belonging to the subgenus Diphascon. These two specimens have three macroplacoids, microplacoid, and hind legs with indented basal margin. The comparison with the species of the subgenus having these characters convinced us to attribute these specimens to a new species, Diphascon (D.) dolomiticum sp. n., which is described and figured in this paper. Materials and Methods The specimens were found in a moss sample on grassland collected in Passo del Grostè (Trento) at 2450 m a.s.l. in September 1988 by R. Bertolani. They are mounted in polyvi- nyl lactophenol; the holotype is deposited in the Binda and Pilato collection (Department of Animal Biology “Marcello La Greca”, University of Catania), the paratype in the Berto- Accepted by C.

Studies on tolerance during embryological stages are rare, but differential effects of desiccation and freezing on different developmental stages have been reported, as well as dose-dependent effect of gamma irradiation on tardigrade embryos. Here, we report a study evaluating the tolerance of eggs from the eutardigrade Milnesium cf. tardigradum to three doses of gamma radiation (50, 200 and 500 Gy) at the early, middle, and late stage of development. We found that embryos of the middle and late developmental stages were tolerant to all doses, while eggs in the early developmental stage were tolerant only to a dose of 50 Gy, and showed a declining survival with higher dose. We also observed a delay in development of irradiated eggs, suggesting that periods of DNA repair might have taken place after irradiation induced damage. The delay was independent of dose for eggs irradiated in the middle and late stage, possibly indicating a fixed developmental schedule for repair after induced damage.

Sc. (McMaster University), B. Sc. (McMaster University) SUPERVISOR: Professor Jonathon R. Stone NUMBER OF PAGES: 124 ii Ph.D. Thesis - T. Vasanthan McMaster University – Biology – Astrobiology LAY ABSTRACT While interest in tardigrade extreme tolerance research has increased over the last decade, many research areas continue to be underrepresented or non- existent. And, while recognized tardigrade species have been increasing steadily in number, fundamental biological details, like individual life history traits, remain unknown for most. The main objectives in this thesis therefore were to survey the life history traits for the freshwater tardigrade species Hypsibius dujardini, increase knowledge about its extreme-tolerance abilities and describe its utility in astrobiological and biological studies. Research involved tardigrade tolerance to hypergravity, pH levels and radiation exposure (and associated radiation-induced bystander effects) as well as responses to temperature changes during development. Findings reported in this dissertation provide new data about H. dujardini, thereby narrowing the information gap that currently exists in the literature for this species. iii Ph.D. Thesis - T. Vasanthan McMaster University – Biology – Astrobiology ABSTRACT Tardigrades are microscopic animals that can survive exposure to multiple extreme conditions.

E-mail: [email protected] Abstract A laboratory strain identified as “Hypsibius dujardini” is one of the best studied tardigrade strains: it is widely used as a model organism in a variety of research projects, ranging from developmental and evolutionary biology through physiol- ogy and anatomy to astrobiology. Hypsibius dujardini, originally described from the Île-de-France by Doyère in the first half of the 19th century, is now the nominal species for the superfamily Hypsibioidea. The species was traditionally con- sidered cosmopolitan despite the fact that insufficient, old and sometimes contradictory descriptions and records prevent- ed adequate delineations of similar Hypsibius species. As a consequence, H. dujardini appeared to occur globally, from Norway to Samoa. In this paper, we provide the first integrated taxonomic redescription of H. dujardini. In addition to classic imaging by light microscopy and a comprehensive morphometric dataset, we present scanning electron photomi- crographs, and DNA sequences for three nuclear markers (18S rRNA, 28S rRNA, ITS-2) and one mitochondrial marker (COI) that are characterised by various mutation rates.

  • Molecular Data Support the Dispersal Ability of the Glacier Tardigrade Hypsibius Klebelsbergi Mihelčič, 1959 Across the Environmental Barrier (Tardigrada)
    Entomol. Mitt. Zool. Mus. Hamburg 17 (194): 233-240 Hamburg, 15. November 2015 ISSN 0044-5223 Molecular data support the dispersal ability of the glacier tardigrade Hypsibius klebelsbergi Mihelčič, 1959 across the environmental barrier (Tardigrada) MIROSLAWA DABERT, HIERONYMUS DASTYCH & JACEK DABERT (with 4 figures) Abstract Two populations of the obligate glacier dweller, the tardigrade Hypsibius klebels- bergi Mihelčič, 1959, have been compared based on the mitochondrial COI gene frag- ment (DNA-barcode), a character hitherto unknown for this species. The animals orig- inated from cryoconite holes on two separated glaciers located at different altitudes in the Ötztal Alps. The lack of divergence in the mitochondrial COI as well as in nuclear 18S and 28S rRNA gene sequences between these two populations indicates the presence of probably only one population on both glaciers separated by a mountain’s ridge. Sequence data of the 18S rRNA gene are compared with such data already available for H. klebelsbergi.

Introduction The eutardigrade Hypsibius klebelsbergi Mihelčič, 1959 (the Hypsibiidae) represents the obligate glacier dweller (Dastych 2009, 2015) recorded so far only from several glaciers in the Austrian Central Alps. The species (Figs 1, 2) inhabits there the water-filled micro-caverns on the glacier surface, so-called cryoconite holes (e.g. Steinbock 1936, 1957, Dastych et al. 2003). Two other taxa, supposedly also obligate glacier inhabitants, Hypsibius janetscheki Ramazzotti, 1968 and H. thaleri Dastych, 2004, have been once only found on the glacier Nero in the Himalayas (Ramazzotti 1968, Janetschek 1990, Dastych 2004 a, b).

A characteristic of this species is the appearance of seasonal cyclic changes in morphology and physiology, i.e. cyclomorphosis. Halobiotus crispae was originally described from Nipisat Bay, Disko Island, Greenland. The present study investigates the distribution of this species and describes the seasonal appearance of cyclomorphic stages at the southernmost locality, Vellerup Vig in the Isefjord, Denmark. Our sampling data indicate that the distribution of H. crispae is restricted to the Northern Hemisphere where we now have found this species at seven localities. At Vellerup Vig data from sampling cover all seasons of the year and all of the originally described cyclomorphic stages have been found at this locality. However, when comparing the lifecycles of H. crispae at Nipisat Bay and Vellerup Vig, profound differences are found in the time of year, as well as the period in which these stages appear.

We reconcile molecular phylogenetics with alpha morphology, focusing on claw and apophysis for the insertion of the stylet muscles (AISM). We combine molecular and morphological evidence to de- fine six new taxa within the Parachela Schuster et al 1980. These include two new families of Isohypsibiidae fam. nov. and Ramazzottidae fam. nov. along with four new superfamilies of Eohypsibioidea superfam. nov., Hypsibioidea super- fam. nov., Isohypsibioidea superfam. nov., and Macrobiotoidea superfam. nov.

Mickiewicz University, Poznań, Poland Abstract This work contributes to the knowledge on distribution, diversity and ecology of the Antarctic soil biota. Different soil habitats from several ice-free coastal sites were sampled along the Victoria Land across 7° of latitude from 71° to 78°S during five austral summer seasons between 2003/04 and 2011/12. In this paper we report preliminary data on soil tardigrades (water bears) from Edmondson Point, Northern Victoria Land. Tardigrades were found to be present in 23 of the 41 examined soil samples (56%). Their presence was associated exclusively with soil samples collected from bryophytes communities and under cyanobacterial mats, whereas they were completely absent in fellfield and ornithogenic soils. Tardigrades were least numerous among all soil micrometazoans, their abundance in the positive samples was very variable and ranged from 3 to 1824 individuals per 100 g of soil DW.
