The karyotype, C-banding, and nucleolar organizer regions (NORs) of six specimens of Hemiechinus auritus from Turkey were examined. The diploid number of chromosomes was 2n = 48, the fundamental number of chromosome arms FN = 96, and the number of autosomal arms FNa = 92. Most of the chromosomes possessed centromeric constitutive heterochromatin, except of the pairs nos. 4, 6, 7, 8, 9, 12, and 17. The X and Y chromosomes appeared to be euchromatic, and possible geographic variation in their morphology was indicated in comparison with previously published data. The NORs were located in the terminal regions of the long arms of four metacentric or submetacentric chromosomes. The localization of the NORs was not associated with C-positive autosomal regions as in hedgehogs of the genus Erinaceus.
Rejskovití hmyzožravci (Soricidae) vydávají v nejrůznějších situacích mnoho typů hlasů. Dospělí jedinci se ozývají, pokud jsou v nebezpečí nebo se dostanou do potyčky s jiným jedincem svého druhu, během námluv a páření nebo při kontaktu s potomky. Také mláďata vydávají nejrůznější hlasy, jimiž se často snaží upozornit na své strádání nebo udržet kontakt s matkou a sourozenci. Přestože v poslední době přibývá publikací zabývajících se problematikou akustické komunikace rejskovitých, je to stále poměrně neprobádaná oblast. Mnohé otázky by mohly být zodpovězeny studiem bělozubky hnědé (Suncus murinus), která dobře prospívá i v péči člověka., Shrews (Soricidae) utter many types of vocalization in various situations. Adult individuals emit vocalizations when they are in danger or in a fight with conspecifics, during courtship and mating or when they keep contact with their offspring. Juveniles utter variable vocalizations mostly to prevent their discomfort and to keep contact with their mother and siblings. Although the number of publications has increased recently, acoustic communication among shrews still remains a quite unexplored field. Our knowledge might be significantly expanded by studying the Asian House Shrew (Suncus murinus), a species that can be successfully kept and bred in captivity., and Irena Schneiderová.
Soricinia tripartita Żarnowski, 1955 is redescribed on the basis of specimens from the type host Sorex araneus Linnaeus from Lithuania, Latvia and Russia (Republic of Karelia and Republic of Komi - a new geographical record) as well as from Sorex satunini Ognev and Sorex volnuchini Ognev from Russia (Nalchik Area in the Caucasus Mountains). The strobilar morphology of S. tripartita is compared with that of other hymenolepidid cestodes of shrews with an unarmed scolex and serial development of proglottides in the strobila, i.e. species of Mathevolepis Spassky, 1948, Ditestolepis Soltys, 1952, Spasskylepis Schaldybin, 1964, Ecrinolepis Spassky et Karpenko, 1983 and Diorchilepis Lykova, Gulyaev, Melnikova et Karpenko, 2006. It was noted that S. tripartita does not correspond to any of the known genera. The following unique characters are found for S. tripartita: heteronomous serial strobilation with one or two sterile proglottides at the end of each series in the strobila and the whole copulatory part of the vagina covered with numerous, fine spines. Therefore, the new genus Gulyaevilepis is erected, with Gulyaevilepis tripartita (Żarnowski, 1955) comb. n. as its type and only species. Since the type material of Soricinia tripartita is not known to exist, a neotype from the same host species and from a locality close to the type locality is designated.
