Note on the distribution of Geolycosa vultuosa (Araneae: Lycosidae) in the "Câmpia Careiului" Natura 2000 site, north-western Romania

Abstract. We identified Geolycosa vultuosa in 11 grassland patches, most of them located in the centre of the protected natural area. These habitats are sandy grasslands with a moderate or high grazing intensity as well as fallow or abandoned lands and a sand pit. The expansion of the species in the area is favoured by the continuously increasing number of sheep flocks which produce suitable habitats for G. vultuosa through grazing

First record of the rare species Pardosa maisa Hippa & Mannila, 1982 (Araneae: Lycosidae) in Romania

The presence of a rare species, Pardosa maisa, is reported for the first time in Romania. Seven males and 4 females were collected in spring, using pitfall traps, from four marshy habitats located near two natural reserves within the Natura 2000 site “Cvmpia Careiului”, northwestern Romania

Seasonal variation in the diet of a population of Hyla arborea from Romania

Abstract. We examined the diet of Hyla arborea over its entire activity period (March to late September, 2004), and analysed a total of 585 adult samples. From the stomach contents we identified plant remains, shed-skin fragments, and animals. We identified a total of 2976 prey items, almost all of which originated from the terrestrial environment. Adult araneans and coleopterans were the most abundant prey items in the diet of the studied tree frogs. Some of the prey items become abundant in certain parts of the year (e.g. Homoptera, Lepidoptera larvae, Trichoptera). The dietary diversity index is high and exhibits seasonal changes. During the period of study an important seasonal change was observed in feeding intensity and in the type of consumed prey. Our results show that Hyla arborea has a broad dietary diversity which was expected as a consequence of exploiting the habitat both vertically and horizontally, possibly allowing access to a broader spectrum of prey
