A Magyar szöcskeegĂ©r (Sicista trizona trizona) hazai maradványpopuláciĂłinak kutatása bagolyköpet-analĂzis segĂtsĂ©gĂ©vel
A magyar szöcskeegĂ©r (Sicista trizona trizona) az egyik leginkább veszĂ©lyeztetett hazai kisemlĹ‘sfajunk. A trizona alfaj csak hazánk terĂĽletĂ©n Ă©l, Ă©s jelenleg egyetlen állományát ismerjĂĽk a Borsodi-MezĹ‘sĂ©g terĂĽletĂ©rĹ‘l, azonban a 2000es Ă©vekben mĂ©g volt adata a Hernád-völgybĹ‘l is. A kutatás cĂ©lja nagyobb mennyisĂ©gű bagolyköpet átvizsgálásával a Hernád-völgyi állomány esetleges kipusztulásával vagy meglĂ©tĂ©vel kapcsolatos kĂ©rdĂ©s tisztázása, továbbá egyĂ©b, potenciális helyekrĹ‘l gyűjtött mintákbĂłl a faj jelenlĂ©tĂ©nek vagy hiányának az igazolása. A rendelkezĂ©sĂĽnkre állĂł Hernád-völgyi Ă©s a szomszĂ©dos kelet-csereháti köpetekbĹ‘l összesen 1491, illetve a Borsodi-MezĹ‘sĂ©g Ă©s az ezzel határos Sajó–Hernád-sĂk egy-egy mintavĂ©teli helyĂ©rĹ‘l pedig 717 zsákmányállatot azonosĂtottunk. A vizsgálat során a bagolyköpetmintákbĂłl összesen 2208 kisemlĹ‘s kerĂĽlt elĹ‘, magyar szöcskeegĂ©r maradványt nem találtuk. A mintavĂ©teli terĂĽ- letek leg jellemzĹ‘bb kisemlĹ‘sfajai a mezei pocok (Microtus arvalis), a Mus-fajok (Mus sp.), az erdeiegĂ©r-fajok (Apodemus sp.) Ă©s az erdei cickány (Sorex araneus) voltak. ----- The Hungarian Birch Mouse is one of the most endangered small mammal species in Hungary. The trizona subspecies lives only in Hungary, with only one known population, located in the Borsodi-MezĹ‘sĂ©g. In the beginning of the 2000s, the species was present in the Hernád-valley. The aim of the study was to clarify the present situation of the species in the Hernád-valley, moreover to obtain new data on the species from other potential localities. 1491 prey items were identified from Hernád-valley and from the neighbouring Kelet-Cserehát and 717 prey items from the Borsodi-MezĹ‘sĂ©g and Sajó–Hernád-sĂk. The species was not present in the observed material, consisted of totally 2208 specimens. The most frequent prey items were the Common Vole, Mus-species, Apodemus-species and Common Shrew
Egy értékes denevérélőhely: Az Eszterházy Károly Főiskola központi épületének padlása
The paper is reporting on the results of the bat observations conducted in the attic of the main building of the Eszterházy Károly Collage between 1991 and 2010. Seven bat species were observed: Rhinolophus ferrumequinum, Myotis myotis/oxygnathus, Myotis emarginatus, Plecotus austriacus, Eptesicus serotinus, Pipistrellus pipstrellus, and Vespertilio murinus. Considerable colonies of Rh. ferrumequinum and Myotis myotis/oxygnathus were discovered. Due to the negative effects of the increasing numbers of pigeons in the attic, the bat population started to decline. In order to revitalise and conserve this significant bat habitat the pigeons should be exluded, and special bat entrances should be installed which could ensure the entrance of bats including the Rh. ferrumequinum, which species has special needs like wide openings through which they can fly into the attic
A Magyar szöcskeegĂ©r (Sicista trizona trizona) hazai maradványpopuláciĂłinak kutatása bagolyköpet-analĂzis segĂtsĂ©gĂ©vel
A magyar szöcskeegér (Sicista trizona trizona) az egyik leginkább veszélyeztetett
hazai kisemlősfajunk. A trizona alfaj csak hazánk területén él, és jelenleg
egyetlen állományát ismerjük a Borsodi-Mezőség területéről, azonban a 2000es
években még volt adata a Hernád-völgyből is. A kutatás célja nagyobb
mennyiségű bagolyköpet átvizsgálásával a Hernád-völgyi állomány esetleges
kipusztulásával vagy meglétével kapcsolatos kérdés tisztázása, továbbá egyéb,
potenciális helyekről gyűjtött mintákból a faj jelenlétének vagy hiányának az
igazolása. A rendelkezésünkre álló Hernád-völgyi és a szomszédos kelet-csereháti
köpetekből összesen 1491, illetve a Borsodi-Mezőség és az ezzel határos
Sajó–Hernád-sĂk egy-egy mintavĂ©teli helyĂ©rĹ‘l pedig 717 zsákmányállatot azonosĂtottunk.

A csĂkos szöcskeegĂ©r helyzete a Hernád-völgyben
A csĂkos szöcskeegĂ©rnek (Sicista subtilis trizona, Frivaldszky 1865) jelenleg mindössze kettĹ‘ elĹ‘fordulási helyĂ©t ismerjĂĽk MagyarországrĂłl. Ezek közĂĽl az egyik a 2006-ban leĂrt populáciĂł a Borsodi- MezĹ‘sĂ©g terĂĽletĂ©rĹ‘l, mĂg a másik az eddig mĂ©ltatlanul mellĹ‘zött hernád-völgyi. UtĂłbbi helyrĹ‘l eddig csak bagolyköpetekbĹ‘l kerĂĽlt elĹ‘; Ă©lĹ‘ pĂ©ldányt valĂłszĂnűleg itt soha nem láttak. 2014-ben bagolyköpet-gyűjtĂ©st Ă©s elemzĂ©st vĂ©geztĂĽnk, amely során rĂ©gebbi mintákat is feltártunk. ElemzĂ©seink alatt egyetlen szöcskeegĂ©r pĂ©ldány maradványai kerĂĽltek elĹ‘ egy 2008-as aszalĂłi gyűjtĂ©sbĹ‘l. A Hernád-völgy alapos bejárása után talajcsapdázást vĂ©geztĂĽnk a potenciális Ă©lĹ‘helyeken. Az egykori elterjedĂ©si terĂĽlet behatárolásához 1960-as Ă©vekben kĂ©szĂĽlt lĂ©gifotĂłkat használtunk, amelyeken a lehetsĂ©ges korábbi Ă©lĹ‘helyek elkĂĽlönĂthetĹ‘k. Csapdázásaink során sajnos nem sikerĂĽlt kimutatni a Hernád-völgybĹ‘l a fajt. ValĂłszĂnűleg a terĂĽlet gyakori Ă©getĂ©se okozhatta a faj eltűnĂ©sĂ©t a terĂĽletrĹ‘l. Azonban mĂ©g további csapdázások szĂĽksĂ©gesek ahhoz, hogy biztosan kijelenthessĂĽk: a szöcskeegĂ©r kipusztult a Hernád-völgyben
Description of a new tick species, Ixodes collaris n. sp. (Acari: Ixodidae), from bats (Chiroptera: Hipposideridae, Rhinolophidae) in Vietnam
Background:
In a recent study on ixodid bat ticks from Eurasia, a high genetic difference was found between
Ixodes vespertilionis
from Europe and Vietnam. Accordingly, it was proposed that
I. vespertilionis
is a species complex,
with at least one additional, hitherto undescribed spe
cies. The aim of the present study was to investigate
the morphology of bat ticks from Vietnam and to asses
s their taxonomic status in comparison with those
collected in Europe.
Findings:
Ixodid bat ticks (two females and two nymphs) collected from the pomona leaf-nosed bat (
Hipposideros
pomona
) (Hipposideridae) and intermediate horseshoe bat (
Rhinolophus affinis
) (Rhinolophidae) in Vietnam showed
major morphological differences from European isolates of
I. vespertilionis
, including the shape of the scutum,
the enclosure and shape of porose areas, the presence of a caudo-lateral collar-like ridge ventrally on the basis capituli,
polytrich coxae with short setae, and grouped (non-linear) arrangement of anterior pit sensillae in Haller
’
sorgan.
Conclusions:
In this study the female and the nymph of an ixodid bat tick species from Vietnam are described for the
first time. The genetic and morphological differences between
I. vespertilionis
Koch,1844andthesebatticks
from Vietnam justify the status of t
he latter as a distinct species,
Ixodes collaris
Hornok n. sp.

Recent remarkable records reveal that Phia Oac-Phia Den Nature Reserve is a priority area for bat conservation in Northern Vietnam
AbstractThree short field surveys were conducted in the Phia Oac-Phia Den Nature Reserve to assess the species diversity and endemism of local bat fauna. In combination with data from a previous study, 24 bat species of 5 families, representing > 20% of the national bat diversity, were recorded in the study area. The occurrence of several bat species restricted to montane forests, that is, Murina chrysochaetes, Pipistrellus coromandra, and a potentially new species Rhinolophus cf. macrotis, suggests that Phia Oac is an important area for bat conservation in Vietnam and thus more comprehensive studies need to be performed
Metagenomic analysis of bat guano samples revealed the presence of viruses potentially carried by insects, among others by Apis mellifera in Hungary
The predominance of dietary viruses in bat guano samples had been described recently, suggesting a new opportunity to survey the prevalence and to detect new viruses of arthropods or even plant-infecting viruses circulating locally in the ecosystem. Here we describe the diversity of viruses belonging to the order Picornavirales in Hungarian insectivorous bat guano samples. The metagenomic analysis conducted on our samples has revealed the significant predominance of aphid lethal paralysis virus (ALPV) and Big Sioux River virus (BSRV) in Hungary for the first time. Phylogenetic analysis was used to clarify the relationship to previously identified ALPV strains infecting honey bees, showing that our strain possesses a close genetic relationship with the strains that have already been described as pathogenic to honey bees. Furthermore, studies have previously confirmed the ability of these viruses to replicate in adult honey bees; however, no signs related to these viruses have been revealed yet. With the identification of two recently described possibly honey bee infecting viruses for the first time in Hungary, our results might have importance for the health conditions of Hungarian honey bee colonies in the future
