Dated back to 1856 and 1875, Schmidl and Frivaldszky described Titanethes graniger, recently known as Mesoniscus grani-ger (Frivaldszky, 1875) from the cave systems of the Aggtelek Karst. Over hundred years later Kontschán (2004) has compiled data collected by several non-isopodologist researchers and listed six widely distributed European species (Ligidium hypnorum (Cuvier, 1792), Haplophthalmus danicus Budde-Lund, 1880, Haplophthalmus mengii Zadd-ach, 1844, Hyloniscus riparius (C. Koch, 1838), Or-thometopon planum (Budde-Lund, 1885), Porcel-lium collicola (Verhoeff, 1907), Protracheoniscus politus (C. Koch, 1841). Our present sampling was the first designed faunistic research on surface ac-tive oniscids in the Aggtelek Karst area. Moreover, Mlejnek et al. (2001) reported occurrences of M. ganiger from caves of Aggtelek area.The Hungarian Northern Ranges (Északi-középhegység), probably owing to its extension and high variety of geomorphological and geological traits, has unique isopod assemblages as it is proven by Allspach (1996), Kontschán (2002, 2003) and Kontschán et al. (2006). Here we find Carpathian species (Ligidium intermedium Radu, 1950, Hylonis-cus transsilvanicus (Verhoeff, 1901), Trachelipus dif-ficilis (Radu, 1950) together with Atlantic-Alpine (Porcellium conspersum (C. Koch, 1841), Armadillid-ium opacum (C. Koch, 1841) isopods while the typi-cal Central and Eastern European faunal elements (e.g. P. collicola, P. politus or Lepidoniscus minutus (C. Koch, 1838) can also be found. Moreover, the area harbours troglobitic isopods and one endemic spe-cies (Haplophthalmus hungaricus Kesselyák, 1930) that is considered (Kesselyák 1928) as an ancient form of other Haplophthalmus species.Our research named “Dolina 2007 Expedition“ aimed to discover and observe the soil and litter dwelling macroinvertebrates (Mollusca, Isopoda) in and around the dolines of the plateau of Alsó-hegy with special respect to microhabitat characteristics. The primary results of the research are stated in the recent paper.MaterIals and Methodssampling areaThe Alsó-hegy (UTM: DU78) is the eastern ex-tension of the Aggtelek Karst area that is geolog-ically connected to the Slovak Karst and is a part of the Aggtelek National Park.

We have chosen 16 do-lines of similar traits (Table 1). During time sam-pling, two persons (F. V. and A.

Time sampling provides data eligible in respect of quantitative data analyses.We used the keys of Kesselyák (1928), Schmölz-er (1965), Gruner (1966) and Schmidt (1997) for identification of woodlice specimens.

All the species found are con-sidered as natives, including several rare ones with small local distribution range (Hornung et al. 2007).The pigmy, rare H. hungaricus is the only Hun-garian endemic isopod with a distribution restrict-ed to the Hungarian Northern Ranges (Forró & Farkas 1998, Vilisics 2007). The troglobitic M. graniger is common in the cave systems of Aggtelek karst and the surrounding countries (e.g. Slovakia, Romania, Serbia), but its occurrence on the surface is a new data for the species‘ Hungarian distribu-tion.The Central- and Eastern European species P. politus, L. minutus, O. planum and Trachelipus ratze-burgii (Brandt, 1833) are inhabitants of natural deciduous forests in Hungary and Central Europe. These isopods along with less frequent species in-dicate a quasi natural area under low human dis-turbance. The Carpathian element T. difficilis (oc-curing in N-Romania, NE-Hungary and S-Poland) is among the rarest species in Hungary, with only two published data from the past 80 years (Allspach & Szlávecz 1990, Allspach 1996).The Atlantic-Alpine P. conspersum (e.g. Holland, NE-France, Germany, Switzerland, Czechia, Slova-kia) is also a rare isopod for Hungary that occurs in higher elevations (above 500 m) in the Northern Ranges, like the Bükk (Forró & Farkas 1998) and 20table 1.

The lack of introduced, cosmopolitan or native gener-alist isopods might indicate a relatively high na-ture conservancy value of the area. Moreover, we believe that the presence of rare and sensitive spe-cies indicates naturally formed isopod assemblag-es with a species composition undisturbed from 22human activity. However, the prevalence of such unique assemblage is no longer guaranteed under the given anthropogenic impacts (e.g. illegal log-ging) increasing in the area.acknowledgeMentsOur research was funded by the ÁOTK-NKB 15714, and National Research Fund (OTKA T 43508) grants.

IntroductIon
The locality of the first faunistical data on Hun-
garian terrestrial isopods were published from 
the Aggtelek Karst. Dated back to 1856 and 1875, 
Schmidl and Frivaldszky described Titanethes 
graniger, recently known as Mesoniscus grani-
ger (Frivaldszky, 1875) from the cave systems 
of the Aggtelek Karst. Over hundred years later 
Kontschán (2004) has compiled data collected by 
several non-isopodologist researchers and listed 
six widely distributed European species (Ligidium 
hypnorum (Cuvier, 1792), Haplophthalmus danicus 
Budde-Lund, 1880, Haplophthalmus mengii Zadd-
ach, 1844, Hyloniscus riparius (C. Koch, 1838), Or-
thometopon planum (Budde-Lund, 1885), Porcel-
lium collicola (Verhoeff, 1907), Protracheoniscus 
politus (C. Koch, 1841). Our present sampling was 
the first designed faunistic research on surface ac-
tive oniscids in the Aggtelek Karst area. Moreover, 
Mlejnek et al. (2001) reported occurrences of M. 
ganiger from caves of Aggtelek area.
The Hungarian Northern Ranges (Északi-
középhegység), probably owing to its extension and 
high variety of geomorphological and geological 
traits, has unique isopod assemblages as it is proven 
by Allspach (1996), Kontschán (2002, 2003) and 
Kontschán et al. (2006). Here we find Carpathian 
species (Ligidium intermedium Radu, 1950, Hylonis-
cus transsilvanicus (Verhoeff, 1901), Trachelipus dif-
ficilis (Radu, 1950) together with Atlantic-Alpine 
(Porcellium conspersum (C. Koch, 1841), Armadillid-
ium opacum (C. Koch, 1841) isopods while the typi-
cal Central and Eastern European faunal elements 
(e.g. P. collicola, P. politus or Lepidoniscus minutus (C. 
Koch, 1838) can also be found. Moreover, the area 
harbours troglobitic isopods and one endemic spe-
cies (Haplophthalmus hungaricus Kesselyák, 1930) 
that is considered (Kesselyák 1928) as an ancient 
form of other Haplophthalmus species.
Our research named “Dolina 2007 Expedition“ 
aimed to discover and observe the soil and litter 
dwelling macroinvertebrates (Mollusca, Isopoda) in 
and around the dolines of the plateau of Alsó-hegy 
with special respect to microhabitat characteristics. 
The primary results of the research are stated in 
the recent paper.
MaterIals and Methods
sampling area
The Alsó-hegy (UTM: DU78) is the eastern ex-
tension of the Aggtelek Karst area that is geolog-
ically connected to the Slovak Karst and is a part 
of the Aggtelek National Park. The sampling area is 
19© Faunima, Bratislava, 2008 http://zoology.fns.uniba.sk/ffs
characterized by numerous depressions (sinkholes 
and dolines) in Triassic limestone formed in shal-
low seas approximately 210–240 million years ago. 
The area is covered with deciduous forests with 
dominating species of oak, hornbeam, beech, ash 
and maple. Table 1 contains data of each doline in-
cluding locality and the EOV (Egységes Országos 
Vetület or Unified National Projection System) co-
ordinates.
sampling methods
Manual samplings have taken place between 
16th and 18th August, 2007. We have chosen 16 do-
lines of similar traits (Table 1). During time sam-
pling, two persons (F. V. and A. N.) have collected 
isopods for 20 minutes in each site, spending 120 
minutes with sampling altogether in each doline. 
Time sampling provides data eligible in respect of 
quantitative data analyses.
We used the keys of Kesselyák (1928), Schmölz-
er (1965), Gruner (1966) and Schmidt (1997) for 
identification of woodlice specimens. Species names 
are used according to Schmalfuss (2003). Samples 
are stored in alcohol (70 %) in the reference collec-
tion of the Institute for Biology at the Szent István 
University, Faculty of Veterinary Science.
Data were handled by the ‚mefa‘ package (Sóly-
mos 2008) in the R environment (R Development 
Core Team 2007).
results
Altogether 10 isopod species were captured in 
the dolines studied. All the species found are con-
sidered as natives, including several rare ones with 
small local distribution range (Hornung et al. 
2007).
The pigmy, rare H. hungaricus is the only Hun-
garian endemic isopod with a distribution restrict-
ed to the Hungarian Northern Ranges (Forró & 
Farkas 1998, Vilisics 2007). The troglobitic M. 
graniger is common in the cave systems of Aggtelek 
karst and the surrounding countries (e.g. Slovakia, 
Romania, Serbia), but its occurrence on the surface 
is a new data for the species‘ Hungarian distribu-
tion.
The Central- and Eastern European species P. 
politus, L. minutus, O. planum and Trachelipus ratze-
burgii (Brandt, 1833) are inhabitants of natural 
deciduous forests in Hungary and Central Europe. 
These isopods along with less frequent species in-
dicate a quasi natural area under low human dis-
turbance. The Carpathian element T. difficilis (oc-
curing in N-Romania, NE-Hungary and S-Poland) is 
among the rarest species in Hungary, with only two 
published data from the past 80 years (Allspach & 
Szlávecz 1990, Allspach 1996).
The Atlantic-Alpine P. conspersum (e.g. Holland, 
NE-France, Germany, Switzerland, Czechia, Slova-
kia) is also a rare isopod for Hungary that occurs 
in higher elevations (above 500 m) in the Northern 
Ranges, like the Bükk (Forró & Farkas 1998) and

conclusIons
Here we present faunistic data on surface dwell-
ing isopods from the Aggtelek Karst region. The 
lack of introduced, cosmopolitan or native gener-
alist isopods might indicate a relatively high na-
ture conservancy value of the area. Moreover, we 
believe that the presence of rare and sensitive spe-
cies indicates naturally formed isopod assemblag-
es with a species composition undisturbed from 
22
human activity. However, the prevalence of such 
unique assemblage is no longer guaranteed under 
the given anthropogenic impacts (e.g. illegal log-
ging) increasing in the area.
