A hatvani SzĂ©chenyi Zsigmond VadĂĄszati MĂșzeum = The SzĂ©chenyi Zsigmond Hunting Museum in Hatvan
Th e opening of the Széchenyi Zsigmond Hunting Museum in the baroque Grassalkovich Mansion in Hatvan, Hungary was the realisation of a 100-year-old dream. Th e Hungarian hunting and fi shing culture and traditions are shown through nine exhibitions on three floors: game species of the Carpathian Basin, clothing, music, art pieces etc. related to or inspired by hunting.
Th e museum uniquely combines traditional elements like display cabinets with interactive computers, which allow the visitor a playful learning experience and thorough understanding of
the role of hunting in our modern, mostly urbanised society. In the park of the castle, in two modern buildings, the so-called âAdventure Placeâ provides the chance for everyone to try shooting with laser guns and bowhunting, which gives an insight into the practices of modern hunting.

Ăzsiai orrszarvĂșak a Magyar TermĂ©szettudomĂĄnyi MĂșzeum gyƱjtemĂ©nyĂ©ben = Asian rhinos in the Hungarian Natural History Museum
Descriptions of a Sumatran rhinoceros Dicerorhinus sumatrensis and a Javan rhinoceros Rhinoceros sondaicus specimen, housed in the Hungarian Natural History Museum are given. The Sumatran rhinoceros was probably captured in Peninsular Malaysia in 1894 and purchased by the Municipal Botanical and Zoological Gardens, Budapest, Hungary, whereas the Javan rhinoceros
was shot by J. XĂĄntus Hungarian explorer in Java in 1869. Both were later donated to the Hungarian Natural History Museum where they are preserved as mounted specimens and some bones. With 6 figure
Old views and new insights: taxonomic revision of the Bukovina blind mole rat, Spalax graecus (Rodentia: Spalacinae)
As a result of their rather uniform external appearance and gross cranial morphology, the systematics of blind mole
rats has been hotly debated over the last century; however, the separation of the large-bodied and small-bodied
blind mole rats at the genus level (Spalax and Nannospalax, respectively), suggested earlier on morphological
grounds, is strongly supported by recent molecular biological evidence. The species of Spalax have so far been
distinguished from each other by cranial traits only, especially the outline of sutures of the cranium, and the shape
and relative size of the nasal and parietal bones. Based on mitochondrial DNA sequences (with the widest
taxonomic and geographic coverage so far) and detailed anatomical comparisons of museum specimens, we
herewith provide a revision of the taxonomic and phylogenetic status of the westernmost representative of the
genus, Spalax graecus s.l. We clarify that antiquus and istricus â presently regarded as synonyms of graecus â are
well-defined species, and they together form a separate clade within Spalax. The robustness of our conclusions is
supported by the combined evidence of morphology, multilocus phylogeny, species distribution, and taxon history
(species congruence with past tectonic and climate events)
European rodent on the edge: status and distribution of the Vojvodina blind mole rat
Recent research of blind mole rats of the species complex Nannospalax (superspecies leucodon) identified a small and fragmented population of these rodents on both sides of the Hungarian-Serbian border. Cytogenetic investigations proved that this population karyologically identical with the Vojvodina blind mole rat described earlier as Nannospalax (leucodon) montanosyrmiensis. Based on cytochrome b gene sequences obtained from three specimens originating from separate locations, these blind mole rats form a discrete phylogenetic clade which, with a difference of about 10%, is well separated from other blind mole rat taxa inhabiting the Carpathian Basin. The taxon has only two extant populations that are 150âkm apart from each other. The combined occupied area is estimated to be less than 10âkm(2), and the total estimated number of individuals is less than 300. These two remaining populations are heavily fragmented and under imminent threat by the establishment of tree plantations, small-scale and agro-industrial farms and land development. The situation is further aggravated by the fact that 80% of the individuals inhabit unprotected areas. A study of the landscape history of the wider area surrounding one of the populations - based on military maps spanning over the last 200âyears - has shown a drastic decrease in the extent and quality of potential habitats. Based on our present knowledge, the Vojvodina blind mole rat is one of the most seriously threatened, rarest mammal in Europe, the remaining population of which can be wiped out within years unless immediate conservation action is taken.

The Alcuin number of a graph and its connections to the vertex cover number
We consider a planning problem that generalizes Alcuin's river crossing problem to scenarios with arbitrary conflict graphs. This generalization leads to the so-called Alcuin number of the underlying conflict graph. We derive a variety of combinatorial, structural, algorithmical, and complexity theoretical results around the Alcuin number. Our technical main result is an NP-certificate for the Alcuin number. It turns out that the Alcuin number of a graph is closely related to the size of a minimum vertex cover in the graph, and we unravel several surprising connections between these two graph parameters. We provide hardness results and a fixed parameter tractability result for computing the Alcuin number. Furthermore we demonstrate that the Alcuin number of chordal graphs, bipartite graphs, and planar graphs is substantially easier to analyze than the Alcuin number of general graphs
