Abstract: A new genus and species, Balogheremaeus chimaera gen. et sp. n. is described after a specimen found in a dry riverbed in Southeastern Spain. A comparison with the rest of the family Plateremaeidae is made. The new genus and species is differenciated from the rest of the family Plateremaeidae due to its smaller size, its convex notogaster, the presence of three pairs of anal setae and the presence of well developed laminated excrescences or crests in its legs, both dorsally and ventrally.
Key words: Acari, Oribatids, Balogheremaeus chimaera, new genus, new species, Plateremaeidae, taxonomy, Spain.

Acta Zoologica Academiae Scientiarum Hungaricae 52 (4), pp. 359–366, 2006 Title: Assessing the effect of toe clipping on the yellow bellied toads Authors: Hartel, T.1 and Nemes, Sz.2
Authors' addresses: 1Mircea Eliade College, str. 1 Decembrie nr. 31, 545400 Sighisoara, Romania. E-mail: asobeka@yahoo.com Abstract: In this paper we analyze/investigate the effect of toe clipping on Bombina variegata, by comparing the body conditions of marked and unmarked individuals. We marked 395 adult B. variegata in 2003 and 413 in 2004. In 2005 we measured the SVL and wet body weight of 27 recaptured individuals and compared this with unmarked individuals from the population. We found no significant effect of toe clipping on the body condition. These results, together with examination of the health of recaptured toads and behavioural data indicates that toe clipping has no negative effect. Nevertheless, caution is needed
in using the toe clipping method because the recently discovered and spreading chytrid fungus that could infect the marked amphibians and cause chytridiomicosis. Key words: toe clipping, body condition, amphibians. Download in

Acta Zoologica Academiae Scientiarum Hungaricae 52 (4), pp. 373–383, 2006 Title: Inquiline effects on a multilocular gall community
Authors: László, Z.1 and Tóthmérész, B.2
Authors' addresses: 1Ecological Institute, University of Debrecen, H-4010 Debrecen, P. O. Box 71, Hungary, E-mail: feherlofia@puma.unideb.hu Abstract: The influence of inquiline on the gall of Diplolepis rosae
(Hymenoptera: Cynipidae) and its community was investigated. It is
expectable that inquilines should cause major changes in the gall-community.
Evidences for inquiline effect on multilocular galls are provided
and the result suggests that the outcome shows similarity with unilocular
ones. Gall size, number of emerged individuals and diversity increased
significantly for inquilined galls. Inquiline-free galls showed highly
significant positive correlation between gall size and number of emerged
individuals. The presence of inquiline entirely annihilated the correlation
between gall size and number of emerged individuals. This radical
change implied within relationships of gall size and specimen number
indicates that inquilines play an important role in shaping the community
structure of D. rosae gall.

Authors: Oláh, Gy.1 and Rózsa,
L.2
Authors' addresses: 1Institute for Zoology, Faculty of Veterinary Sciences, Szent István University, H-1077 Budapest, Rottenbiller u. 50, Hungary. E-mail: olahgy@t-online.hu Abstract: Pathogens of both avian and mammalian fecal origin can infect birds
via drinking water. Since birds often use ultraviolet clues for many
decisions such as food detection, they may also be able to distinguish
between faeces- or urine-polluted water and clean water by using UV
vision. Here we test the hypothesis that birds may assess potential
pollutions in drinking water bodies using UV absorptions/reflections.
Feral pigeons were offered with (1) clean tapwater, (2) uric acid
polluted water (UV-absorbant) to mimic wastes of avian origin and
(3) urea solution (UV-reflectant) to mimic wastes of mammal origin.
Contrary to our expectations, pigeons exhibited no detectable preferences
in double-choice experiments. Key words: pigeon, nitrogen metabolism, water preference,

Acta Zoologica Academiae Scientiarum Hungaricae 52 (4), pp. 407–415, 2006 Title: Occurrence of Dactylogyrus infection linked to seasonal changes and host fish size on four cyprinid fishes in Lake Manyas, Turkey
Authors: Öztürk, M. O.1 and Altunel, F. N.2
Authors' addresses: 1Department of Biology, Faculty of Science and Literature, Afyon Kocatepe University, Afyon 03200 Turkey; E-mail: oozturk@aku.edu.tr Abstract: In this study, dactylogyrid parasites on the gills of four cyprinid
fishes (Blicca bjoerkna, Rutilus rutilus, Scardinius erythropthalmus,
Vimba vimba) in Lake Manyas, Turkey, were examined on the basis
of samples taken from on-site surveys carried out between January–1997
and November–1998. The intensity of Dactylogyrus infection
was investigated depending on the parasite species, the years and
seasons, and host fish size. Four Dactylogyrus species were
identified on the gills of host fishes: D. sphyrna on B.
bjoerkna, D. crucifer on R. rutilus, D. difformis
on S. erythrophthalmus, D. cornu on V. vimba.
The prevalence and mean intensity of Dactylogyrus infection
for each parasite species was determined as follows: D. crucifer
(41.5%, 10.65±5.79 specimens/fish), D. cornu (14.2%, 30.24±11.30),
D. difformis (28.1%, 31.71±30.95), D. sphyrna (28.7%,
16.76±16.88). While maximum intensity was recorded for D.
difformis, the lowest was for D. crucifer. However, it
was not a statistically meaningful difference for all the parasite
species. As regards the prevalence of the parasite species depending
on the years, it was observed higher in 1998 than in 1997. Regarding
the seasonal changes in the intensity and prevalence level, a very
sharp decrease in the intensity levels of the parasite species was
determined for the three fish parasites, except D. crucifer,
between the late autumn and winter.

Title: Daytime activity of reed passerine birds based on mist-netting Authors: Trnka, A.1, Szinai, P.2 and Hosek, V.3
Authors' addresses: 1Department of Biology, Trnava University,
Priemyselná 4, 918 43 Trnava, Slovakia, E-mail: atrnka@truni.sk Abstract: Capture rates of eight reed passerine birds in relation to time of
day were studied in the late breeding periods of 1999–2004 in
National Nature Reserve Parízske mociare marsh (SW Slovakia). Based on 3700 captures, significant differences in mean
capture times were found among species in both morning and evening.
Capture rates of birds differed significantly also between the first
and last 5 hours of daylight. Moustached Warbler, Sedge Warbler and
Bearded Tit were most active in the morning, and Marsh and Reed Warblers
in the evening. Adult daily activity differed considerably from that
of juvenile in Bearded Tit, Reed and Moustached Warblers. We suggest
that only morning sampling alone does not give an accurate estimate
of relative abundance and age structure of reed passerines in mist-netting
studies. A recommended regime would be to begin netting four hours
before sunset and continue four hours after sunrise the next day on
each visit.
Key words: capture efficiency, bird activity, Savi's Warbler, Reed Bunting.
