Abstract: Benthic fauna samples were taken from a sandy submerged eulittoral site at Lake Sakadas, Kopacki rit (Croatia) from November 1997 to December 1998. The meiofauna and freshwater nematode abundance pattern and diversity were analysed with regard to water-level fluctuations and seasonal temperature changes. Meiofauna abundance and diversity showed temporal variations. The nematode relative abundance varied from 4% up to 90% of total meiofauna abundance, although totally absent in August. In total, 26 nematode species were recorded. The composition of nematode species depends on water-level fluctuation. Water levels above 200 cm drasticaly changed the composition of species. Brevitobrilus stefanskii, Tobrilus gracilis and Mononchus aquaticus chewers were the dominant species during the low and the middle water level, and suction feeders were dominant during the high water-level. Temperature and water-level fluctuations determined the diversity and abundance of the benthic fauna in the submerged eulittoral zone of Lake Sakadas.

Abstract: Fruit bearing shoots of 139 leguminous species (cca 86% of known species of Leguminosae in Hungary) were collected at 148 sites all over the country since 1978. Only 54 species (38.8%) were found to host altogether 43 weevil species. The rearing method largely reduced the probability of getting adult weevils that may have used a plant only as an adult food source or only as refuge. This strongly increased the reliability of the host plant data obtained. The host plant range showed great differences within and between weevil genera. From the 54 plant species found as hosts, 29 and 11 (altogether 74.1%) harboured only one and two weevil species, respectively. The resource exploitation rate turned out very low at the plant species level.

Title: A description of the song of Pholidoptera transsylvanica (Fischer-Waldheim, 1853) (Orthoptera: Tettigoniidae)

Abstract: The song of Pholidoptera transsylvanica, a (sub-)endemic bush-cricket of the Carpathian Basin, is described for the first time. The songs of 9 specimens from Hungary and Transylvania (Romania) have been analysed. The stridulatory file was 3.94.3 mm long and contained 106121 stridulatory pegs (a scanning electron microscopic photo of the stridulatory file is presented). Oscillographic analysis showed that the song is composed of regularly or sporadically repeated trisyllabic echemes. The duration of echemes was temperature dependent (r = 0.9881, p<0.001) D = 13.39 * T + 456.69 [where D is the duration of echeme in ms and T is the ambient air temperature in °C between 21 and 28 °C]. Echeme-repetition rate varied widely (23133 echemes per minute at 2628 °C). The relationship between the song of Ph. transsylvanica and that of the other species of Pholidoptera occurring in the Carpathian Basin is discussed.

Abstract: Hunting behaviour and use of different habitat types of a breeding Great Grey Shrike family was observed in a recycled landfill near Eilat, Israel. As Great Grey Shrikes were not observed to breed in the Eilat area for more than a decade, detailed observations of hunting site selection were conducted. Additionally, arthropod abundance and impaled prey items were monitored. The breeding pair established its territory on the boundary of the "Bird Sanctuary", a former recycled landfill, where irrigation has facilitated the growth of dense vegetation inside the park boundary, while outside of it the sparse vegetation characteristic of semideserts is found. Huntings were categorised as either inside or outside of the Bird Sanctuary. White-water traps were applied to measure insect availability inside and outside the Bird Sanctuary. We found that the shrikes foraged preferentially within the Bird Sanctuary (Paired t-test, N=150, t-value: 3.63, P< 0.005). Diversity (revealed by Rényi diversity index) and abundance of arthropods were considerably higher inside the Bird Sanctuary (Wilcoxon Matched-pairs Signed-ranks test, z-value > 2.428, P = 0.0152). The monitoring of impaled prey items revealed that besides insects vertebrates were also taken. Interestingly two specimens of the poisonous Black Cone-headed Grasshopper (Poikylocerus bufonicus) were also impaled and consumed.
