Comparative genomics of the tardigrades Hypsibius dujardini and Ramazzottius varieornatus
Tardigrada, a phylum of meiofaunal organisms, have been at the center of discussions of the evolution of Metazoa, the biology of survival in extreme environments, and the role of horizontal gene transfer in animal evolution. Tardigrada are placed as sisters to Arthropoda and Onychophora (velvet worms) in the superphylum Panarthropoda by morphological analyses, but many molecular phylogenies fai...
متن کاملRamazzottius thulini (Pilato, 1970) bona species and description of Ramazzottius libycus sp. nov. (Eutardigrada, Ramazzottidae).
Comparing the type series of Ramazzottius thulini with specimens of Ramazzottius oberhaeuseri, from the locus typicus, we confirmed there are morphological and metric differences between these two species. This evidence convinced us that R. thulini should be considered a bona species. A new species, Ramazzottius libycus sp. nov., is also described. Ramazzottius libycus sp. nov. differs from R. ...
متن کاملAnalysis of DNA Repair and Protection in the Tardigrade Ramazzottius varieornatus and Hypsibius dujardini after Exposure to UVC Radiation
Tardigrades inhabiting terrestrial environments exhibit extraordinary resistance to ionizing radiation and UV radiation although little is known about the mechanisms underlying the resistance. We found that the terrestrial tardigrade Ramazzottius varieornatus is able to tolerate massive doses of UVC irradiation by both being protected from forming UVC-induced thymine dimers in DNA in a desiccat...
متن کاملA new tardigrade Doryphoribius maasaimarensis sp. nov. (Eutardigrada: Hypsibiidae) from Kenya.
A new tardigrade, Doryphoribius maasaimarensis sp. nov., is described from a moss sample collected in Masai Mara Game Reserve, Kenya. The new species is characterized by having a reticulate dorsal cuticle with small tubercles; nine transverse rows of dorsal gibbosities (configuration IX:4-6-4-6-4-6-4-4-2); pharyngeal bulb with two macroplacoids and no microplacoid; claws with short and thin acc...
متن کاملAnalysis the morphometric features of KabirKooh landslide
The KabirKooh landslide was studied as one of the immediate catastrophic events which causes falling rocks from the KabirKooh hillside and the obstruction of the Seymarreh river course and also formed a lot of geomorphological shapes in this area. This landslide was located at 5 km of the Poldokhtar city at the south between the Ilam and Lorestan province. The main purpose of this research to ...
