Abstract: This paper provides the descriptions and illustrations of two new species of the nematode genus Aporcelaimellus (family Aporcelaimidae). Aporcelaimellus salsus sp. n. from the United States is characterized by the medium-sized body, short odontostyle, unsclerotized vulva, conical, dorsally not concave tail with distinctly separated layers of terminal cuticle. Aporcelaimellus acaudatus sp. n. from Ecuador is distinguished by the large body, sclerotized vulva and especially by the exceedingly short and blunt tail with strongly thickened inner layer of terminal cuticle.

2010 Title: A characterisation of the pair forming acoustic signals of Isophya harzi (Orthoptera, Tettigonioidea, Phaneropteridae)
Authors: Orci, K. M.1, Szövényi, G.2 and Nagy, B.3
Authors' addresses: 1Animal Ecology Research Group of the Hungarian Academy of Sciences and Hungarian Natural History Museum, H-1088 Budapest,
Baross u. 13, Hungary, E-mail: kirill@nhmus.hu Abstract: This study gives the first description of the male calling song and
male-female duet of Isophya harzi, an Eastern European bush-cricket
species known as an endemism of the Cozia Mountains (Southern Carpathians,
Romania). The male calling song is a long sequence of syllable groups.
Each group is composed of two syllable types and the song can be formulated
as A…A – BA…A – BA…A – B (where "A…A"
means a varying number of "A" syllables, and "–"
means a longer inter-syllable interval). Females emit their short
response songs after the "B" syllables of the male song
with a response delay of 125–186 ms from the beginning of the
male syllable. The male calling song has a wide band frequency spectrum
with intensive components between 15–30 kHz. The oscillographic
pattern of the male song resembles that of the songs of Isophya
beybienkoi and I. posthumoidalis. However, syllables are
distinctively longer, repeated at a lower rate and "A…A"
syllable groups contain less syllables in Isophya harzi than
in the other two species. The stridulatory file consists of 100–130
pegs. Our results support the validity of the specific status of this
narrow range, vulnerable bush-cricket.

Title: The body size, age structure and growth pattern of the endemic Balkan mosor rock lizard (Dinarolacerta mosorensis Kolombatovic, 1886)

Authors' addresses: 1Department of Evolutionary Biology, University of Belgrade, Institute for Biological Research "Sinisa Stankovic" Bulevar Despota Stefana 142, 11060 Belgrade, Serbia, E-mail: natasha@ibiss.bg.ac.rs Abstract: The Mosor rock lizard (Dinarolacerta mosorensis) is a distinctly flattened endemic species that occupies discontinuously distributed
rocky areas at high elevations in the Dinaric Mountains of the Balkans.
The body size, age structure, longevity, survival rates and growth
patterns of this species were studied using skeletochronology and
back-calculation methods. The modal age was found to be 5 years for
males and 6 years for females, while the maximal longevity was found
to be 9 years in both sexes. The age and body length were positively
correlated in both sexes. Both sexes reached maturity at 3 years,
with a snout-vent length of 53.3 and 56.5 mm for males and females,
respectively. The growth coefficient had significantly higher values
in females (0.54) than in males (0.40). The asymptotic size of females
was lower (66.01 mm) than that of males (70.82 mm). The growth rate
of females decreased soon after maturation whereas males continued
to grow for a longer time. Juveniles had lower survival rates than
adults (0.5 vs 0.7). The effective age at maturity (13.5 months) was
significantly greater than that for the small lacertid lizards living
at the low altitudes of a Mediterranean climate, greater than but
within the range of values predicted for those living at low altitudes
of a temperate climate, and lower than but within the range of values
predicted for montane small lacertids.

Title: The migratory fattening of the Barn swallow Hirundo rustica in Hungary

Authors' addresses: 1BirdLife Hungary, H-1121 Budapest, Költõ u. 21, Hungary, E.mail: @.hu Abstract: Studies conducted within the framework of the EURING Swallow Project in the Mediterranean area pointed out that the fattening of Barn Swallows
is dependent on the distance they need to cover to pass over ecological
barriers, such as sea and desert via their migration route. Our study
was conducted at inland sites and we analysed the data in comparison
to results previously obtained in the western Mediterraneum. Barn
Swallows were captured at two roosting sites in Hungary: Ócsa
peat bog and Izsák, at Lake Kolon between 2000–2002 with
tape-luring set up each day one and a half hours before sunset. During
the study period 7000 adult and 36000 juvenile Barn Swallows were
caught. Wing length, 3rd primary length, tail length, body mass and
fat score were measured for all adults and for the first 100 juveniles
birds each night. Based on the dynamics of fat accumulation the study
period was separated to a post-breeding, a transitional and a pre-migratory
phase. The observed pattern between years and sites were similar,
and there were recaptures during the same autumn between the two roosting
sites (60 km from each other) to north and to south direction as well.
Our results can not exclude one of the two alternative hypotheses
on Barn Swallow migration strategy that is: (1) Barn Swallows build
up their fat reserves in Hungary and afterwards they maintain it while
slowly reaching the ecological barriers, and (2) Barn Swallows capable
of a non-stop migration from Hungary to the southern edge of the Sahara.
Efforts to find important refuelling sites in the eastern Mediterranean
are needed to support any of the hypotheses.

Title: Spatial, temporal and individual variability
in the autumn diet of European hare (Lepus europaeus) in Hungary
Authors: Katona, K.1, Biró, Zs.1, Szemethy, L.1, Demes, T.2 and Nyeste, M.2
Authors' addresses: 1Szent István University, Institute for Wildlife Conservation, H-2103 Gödöllõ, Páter Károly u. 1, Hungary, E-mail: katonak@ns.vvt.gau.hu, bzsolti@ns.vvt.gau.hu Abstract: The number of European hares (Lepus europaeus Pallas, 1778) has been on the decline for several decades, mainly due to the
intensification of agriculture that has decreased variability in the
hare"s food supply. Therefore, our aim was to investigate the
variability in the diet of hares in agricultural, pastural and woody
habitat types. Microhistological analysis of stomach contents was
used to define the plant species eaten by hares. Our results show
that the European hare diet is greatly varied (24 species were eaten).
The dominant cultivated species in the diet was wheat, Triticum
aestivum. Grasses and browses were also important food components
in every area. Among browses we found a generally high consumption
of elderberry, Sambucus spp. Hares consumed forbs and seeds
in smaller proportions. When possible, hares select a varied diet;
even in faeces collected in different cultivations the given cultivated
plant species was not dominant. Individual variability in diet composition
was also high. Hare habitats should be improved by providing patchy
habitat with various field edges, which are connected together (green
corridor system). Elderberry should be grown in hedges, and wheat favoured in monocultures.
Key words: cultivated plants, elderberry, habitat heterogeneity
