A two-year-old male ferret (Mustela putorius furo) was presented to the Faculty of Veterinary Science, Szent István University, for investigation of somnolence. Following unsuccessful therapeutic attempts, the ferret was euthanased and a male Dirofilaria immitis worm was found in the pulmonary artery and a female D. immitis specimen in the subdural space of the cranial cavity. To the authors' knowledge, this is the first European record of D. immitis infection in a ferret, and the first case in which aberrant larval migration and consequent central nervous system signs were observed in a ferret in the course of D. immitis infection. © 2010 British Small Animal Veterinary Association.

Background: The axial skeleton is one of the defining evolutionary landmarks of vertebrates. How this structure develops and how it has evolved in the different vertebrate lineages is, however, a matter of debate. Vertebrae and vertebral structures are derived from the embryonic somites, although the mechanisms of development are different between lineages.Discussion: Using the anecdotal description of a teratological newt (Triturus dobrogicus) with an unusual malformation in its axial skeleton, we review, compare, and discuss the development of vertebral structures and, in particular, the development of centra from somitic cellular domains in different vertebrate groups. Vertebrae development through re-segmentation of the somitic sclerotomal cells is considered the general mechanism among vertebrates, which has been generalized from studies in amniotic model organisms. The prevalence of this mechanism among anamniotes is, however, controversial. We propose alternative developmental mechanisms for vertebrae formation that should be experimentally tested.Summary: Research in model organisms, especially amniotes, is laying the foundations for a thorough understanding of the mechanisms of development of the axial skeleton in vertebrates, foundations that should expand the extent of future comparative studies. Although immersed in the '-omics' era, we emphasize the need for an integrative and organismal approach in evolutionary developmental biology for a better understanding of the causal role of development in the evolution of morphological diversity in nature. © 2013 Buckley et al.; licensee BioMed Central Ltd.

We give an overview of the Vipera berus killing and collecting in Hungary between 1950-1970, based on a review of the forestry and hunting periodicals published in Hungary during this period and the collection catalogues of Museum's that store Hungarian adders. Peculiarly the killing of adders was encouraged or even funded by the Hungarian state authorities almost 50 years after the last big slaughter of "venomous snakes" in Europe (last known from Carinthia in 1916). Data on 1008 collected and killed adders have been gathered, from the three geographical regions of Hungary inhabited by the species. Thus 676 specimens (33.8 spec./year) are known to have been removed from the Zemplén Hills, most of them on request of the local Forestry Commission; 198 (9.9 spec./year) from the Valley of the Upper Tisza River, respectively 134 (6.7 specimens/year) specimens collected in Somogy and Zala counties for scientific purposes. © NwjZ, Oradea, Romania, 2010.

Amphibians are globally threatened, but not all species are affected equally by different threatening processes. This is true for the threat posed by the chytridiomycete fungus (Batrachochytrium dendrobatidis). We compiled a European data set for B. dendrobatidis to analyze the trends of infection in European amphibians. The risk of infection was not randomly distributed geographically or taxonomically across Europe. Within countries with different prevalence, infection was nonrandom in certain amphibian taxa. Brown frogs of the genus Rana were unlikely to be infected, whereas frogs in the families Alytidae and Bombinatoridae were significantly more likely to be infected than predicted by chance. Frogs in the 2 families susceptible to B. dendrobatidis should form the core of attempts to develop spatial surveillance studies of chytridiomycosis in Europe. Ideally, surveys for B. dendrobatidis should be augmented by sampling the widespread genus Pelophylax because this taxon exhibits geographically inconsistent overinfection with B. dendrobatidis and surveillance of it may facilitate recognition of factors causing spatial variability of infection intensity. Several European amphibian taxa were not represented in our data set; however, surveillance of unsampled species should also occur when warranted. © 2013 Society for Conservation Biology. Source

In order to stop the decline of Hungarian meadow viper Vipera ursinii rakosiensis, in 2004 MME BirdLife Hungary together with national parks and Budapest Zoo started a complex conservation programme, supported by the European Union LIFE-Nature fund. The Hungarian Meadow Viper Conservation Centre was established with 16 adult individuals, collected from six different populations. By 2013 the number of vipers bred reached c. 1700 individuals. First reintroductions took place in March 2010, with 30 adult snakes released into a reconstructed habitat in Kiskunság National Park. By 2013, a total of 240 snakes had been released into three locations. Snakes were released by relocating the animals in the artificial burrows they used in the semi-natural terrariums at the Hungarian Meadow Viper Conservation Centre. At the release sites vipers were recorded 255 times during post-release monitoring, and 69 individuals were identified. Eighteen of the observed ♀♀ were gravid, and ten juvenile or subadult individuals were documented. In order to develop a remote-tracking method, pre-programmed radio-tags with a detection range of 200-300m were surgically implanted into the abdomens of 16 vipers. These tags also operated as temperature loggers, recording data every 5 minutes for one year. Zoos play an important role in communicating the results of this captive-breeding and release programme. Exhibits of live Hungarian meadow vipers are located at Budapest Zoo and Schönbrunn Zoo in Vienna, Austria, and there are information points about the species located in all Hungarian zoos. © 2014 The Zoological Society of London.
