Article
The distribution of many species is fragmented due to human activities and isolated populations are often affected by genetic changes. Small populations are endangered by inbreeding depression, often leading to a low mean fitness of small populations and to an increased extinction risk. Using museum samples of protected Microtus oeconomus mehelyi f...
Article
The current range of the root vole (Microtus oeconomus) in Europe has been shaped by climate changes, including the last glaciation. In Central Europe there are two isolated subspecies: M. oeconomus mehelyi and M. oeconomus arenicola occurring in the Pannonian lowland and the Netherlands respectively. M. oeconomus stimmingi is present in the northe...

We provide 79 data of 53 collecting events originating from the Sălaj-region of western Transylvania, Romania between 22. April, 2014 and 10. September, 2015. Geographical, spatial and temporal records are documented for the better knowledge of nine amphibian and seven reptilian species. We remark that the number of roadkilled animals is very high...

Myxozoans (Cnidaria: Myxozoa) are almost exclusively endoparasites of aquatic vertebrates and invertebrates, with the notable exception being two species of Soricimyxum Prunescu, Prunescu, Pucek et Lom, 2007 described from terrestrial shrews (Soricidae) in central Europe. Myxospores of the two parasites are morphologically indistinguishable, but ha...

In conservation biology increasingly more countries are using the IUCN categorization (IUCN category and criteria) to describe species occurrence and population dynamics. Although, the evaluation process of the categories is strict, the category and criteria might change, due to different spatial levels (continent, country, region), which often pro...

The present study reconsiders the status of the genus Hokkaidocephala Tenora, Gulyaev & Kamiya, 1999 by examining available specimens of the type species H. apodemi (Iwaki, Tenora, Abe, Oku & Kamiya, 1994) (syn. Andrya apodemi) and comparing them with related anoplocephaline cestodes. It is shown that Hokkaidocephala apodemi does not differ fundame...

This study presents extensive molecular phylogenetic and morphometric data for Anoplocephaloides dentata (Galli-Valerio, 1905)-like cestodes (Anoplocephalidae) and related species parasitizing arvicoline rodents (voles and lemmings) in the Holarctic region. The molecular phylogeny is based on nucleotide sequences of cytochrome oxidase I (mtDNA) and...

The southern birch mouse, Sicista subtilis (Pallas, 1773), is one of the rarest and least known small mammal species in europe. At present, the occurrence of its subspecies, the S. subtilis trizona (Frivaldszky, 1865), is confined to Hungary. The last living individual of this rare subspecies was caught in 1926. Prior to 2006, individuals were dete...

The skulls of the two members of the genus Mus, the outdoor, aboriginal Mus spicilegus and the commensal M. musculus can be differentiated using the zygomatic coefficient (CZ). However, the CZ-method does not differentiate all Mus specimens because the cranial measurements needed to calculate CZ are subjective due the unfixed endpoints. Measurement...

Although the vole genus Microtus is the most speciose group within the subfamily Arvicolinae these species are morphologically quite uniform. The East European vole (Microtus levis) is the sibling species of the common vole (Microtus arvalis) and their distribution area partially overlap. The two species can be distinguished upon skull, baculum and...

Isolated by hundreds of kilometers from the main population, the southernmost populations of root voles (Microtus oeconomus) are vulnerable to extinction in Hungary. Due to restrictions imposed by their protected status, only a limited number of surveys have been conducted to assess the status of the Hungarian populations. Our goal was to understan...

The present study was designed to test the hypothesis that the anoplocephalid cestode Paranoplocephala omphalodes (Hermann, 1783), a Holarctic parasite of Microtus voles, is a complex of host-specific species, rather than a single host-generalist species, using uni- and multivariate morphometrics and DNA sequence data from the mitochondrial cytochr...

The root voles (Microtus oeconomus) is endangered in Hungary; the monitoring of its fragmented and isolated populations is necessary for an effective nature conservation management. Analysing of microsatellite DNA has been shown to be an efficient method to assess genetic variability among a wide variety of organisms. The present paper describes ho...

Taeniid larvae were found in the peritoneal cavity of Daurian pika (Ochotona daurica) in Mongolia. The encysted larvae have a pseudosegmented body, bladder and tail. The scolex is armed with two rows of long hooks with relatively long blade and short base, 34-38 in number. The length of large hooks ranges from 0.266 to 0.314 mm and that of small ho...

Hooks of five species of taeniid tapeworms were scanned at high resolution. After tracing the objects, automated extraction of outline and landmark data was carried out using a computer program written in AutoLISP. Morphometric variation was studied by elliptical Fourier analysis, canonical variate analysis and minimum spanning trees for both landm...

The stimulatory effect of a new analogue of chicken I. gonadotropin-releasing hormone (Folligen) has been studied on specimens of marsh frog, Rana ridibunda. Folligen increased plasma testosterone (T) levels and induced breeding behaviour both during and out of the spawning season. Folligen (GnRHa) significantly enhanced plasma T levels in frogs te...
