Abstract: I studied the area requirement of reedbed breeding passerine birds on 109 reed islands in Lake Velence, Hungary, in the breeding seasons of 1993 and 1994. The size of the smallest occupied reed island for the observed 8 passerine bird species varied from 0.02 ha (Savi"s Warbler Locustella luscinioides) to 4.14 ha (Bluethroat Luscinia svecica). Three species occupied reed islands which were 8–18 times larger than their territory sizes (Sedge Warbler Acrocephalus schoenobaenus, Moustached Warbler A. melanopogon, and Bluethroat), three species occurred on reed islands 4–4.5 times larger than territory sizes (Great Reed Warbler A. arundinaceus, Reed Warbler A. scirpaceus, and Reed Bunting Emberiza schoeniclus), and two species occurred on islands half the size of their territory sizes in continuous reedbeds (Bearded Tit Panurus biarmicus, Savi"s Warbler). This may suggest that the latter two species can utilise groups of small patches within a territory. The incidence functions showed that the probability of occurrence of the Moustached Warbler and the Bluethroat was not 1 even on the largest reed islands (7–25.7 ha), while it was 1 for the other 6 species. The importance of landscape matrix type in determining minimum area requirements was demonstrated using data on the occurrence of bird species in reed marshes within an agricultural landscape in the Po Plain (Italy). In this landscape much larger minimum areas were found than at Lake Velence.

Abstract: To study the short-term effect of leaf-litter manipulation on the structure of carabid assemblage in a 50-year-old Norway spruce plantation in Hungary, pitfall samples from leaf-litter plots (leaf-litter addition) and control plots (no manipulation) were compared during the growing season in 2000. The most frequent species, Pterostichus oblongopunctatus, was significantly more numerous in the leaf-litter samples than in the control ones, indicating the leaf-litter preference of this species. Leaf-litter addition had no significant effect on the abundance of the other four dominant carabid species (Carabus violaceus, Cychrus caraboides, Abax parallelepipedus, Molops piceus). Difference in the number of collected carabid individuals, species richness and the Shannon diversity between the control and the manipulated plots were not significant. The observed leaf-litter preference of Pterostichus oblongopunctatus could be explained with the microhabitat variations and/or the interspecific interactions. Leaf-litter addition altered the microclimatic conditions (lower ground temperature, higher amount of prey items) and produced favourable microhabitat conditions that could influence the spatial distribution of Pterostichus oblongopunctatus. Moreover, the number of carabid larvae was significantly higher in the leaf-litter plots, indicating that the leaf-litter plots with their favourable conditions may be advantageous egg-laying sites.

Title: Population genetics of Philaenus spumarius on the Istranca Mountains: II. Polymorphism and phenotype frequency

Author: S. Yurtsever

Abstract: Genetically controlled colour polymorphism of the meadow spittlebug Philaenus spumarius in the populations of the Istranca Mountains was investigated. A total of 7,544 spittlebugs, 2,936 females and 4,608 males collected from three different types of deciduous forest were analysed. Four non-melanic – populi (POP), typicus (TYP), trilineatus (TRI), vittatus (VIT), – and four melanic – marginellus (MAR), lateralis (LAT), flavicollis (FLA), leucocephalus (LCE) – phenotypes expressed by six different alleles were determined. Melanic phenotypes were limited to the female sex only, moreover the melanic "O" group was not found in the 29 different populations sampled. POP+TYP were predominant phenotypes in the pooled samples (94%). The combined melanics and TRI+VIT were present at equal proportions (3% each). The average sample size for 40 sampling sessions was (Mean±S.E.) 187.1±14.3 (range: 31–361).

Abstract: Although the tree sparrow (Passer montanus) is a widespread species, its social behaviour in winter flocks is poorly known. In this study, we investigated whether (1) flock members form dominance hierarchies in their winter flocks, and (2) whether the size of the black throat patch (the "badge") of birds is correlated with their dominance ranks, i.e. may have a status signal function. We found that tree sparrows formed linear dominance hierarchies in two of the three captive flocks we studied. The dominance rank of birds was positively correlated with their aggressiveness during feeding, i.e. high ranking birds initiated a higher proportion of their aggressive interactions than subordinates. Our results do not support unambiguously the status signalling function of the badge. On the one hand, badge size was the only significant predictor of dominance rank in one flock. In this flock, fighting frequency increased with increasing similarity of badge sizes and fights were especially common when both opponents had large badges. On the other hand, dominance rank was unrelated to badge sizes in the other two flocks. We suggest some factors that may contribute to the observed differences among flocks in the association between badge size and dominance rank.
