(Heteroptera: Rhyparochromidae: Lethaeini) from Papua New Guinea and Indonesia, are described and discussed. Comparing the general habitus of the specimens to other Lethaeini genera, they are most closely related to the genus Aristaenetus but the differences validate a new subgenus.

Abstract: We have studied how individual decisions about timing of breeding and nest location affected the reproductive success of rooks by tracing the formation of a rook breeding colony in Hortobágy National Park (Hungary), during the breeding season in 1999. We have found that birds who built nests earlier also laid eggs earlier and had larger clutch size but had no more offspring than late nesters. Distance of the nest from the centre or edge of the colony did not affect the reproductive success though rooks generally settled closer to the centre and further from the edge than it can be expected by assuming random distribution. The colony showed high breeding synchrony since date of egg laying varied less than date of nesting but synchrony did not influence the breeding success. Hatchling's survival rate and number of offspring increased with local nest density and rooks clustered their nests more than it can be expected by random settlement. Nest sites of early and late nesters did not differ regarding the distance from the centre or the edge of the colony but late nesters chose nest sites in more densely populated regions. The results indicate that individuals may follow different strategies to increase their reproductive success. It is prospectively advantageous to build the nest and lay eggs earlier, in turn, it's worth nesting in already more densely nested areas for late beginners. We suggest that a game theoretical approach may be useful if we try to understand the adaptive significance of colonial breeding.

Key words: Corvus frugilegus, coloniality, colony structure, colony formation, breeding success, clutch size, hatching success, nest density, nest site selection, colony syncrony.

Abstract: The feeding of the Stone Marten (Martes foina) and the Red Fox (Vulpes vulpes) being flexible, easily adapt to anthropogenic food sources, utilising them effectively. Both carnivores feed on plants, thus the question arises how their food composition changes during the seasons when there is high availability of fruits in their habitat. The diet composition of the two species was investigated for one year in a 14-hectare vineyard surrounded by orchards, based on scat analysis (n = 288 and 110, respectively). The proportion of plant matter in the feeding of both species was strikingly high, although differing seasonally, especially fruits, mostly sour cherries, cherries, grapes and figs being present. Martens consumed plants in greater amounts (89% vs 76%) than foxes. Both carnivores consumed more invertebrates in spring, and more small mammals in winter, whereas frugivory was more substantial in the summer and autumn periods. Trophic niche was quite narrow in both species, with considerable degree of overlap. The revealed feeding patterns are quite novel, that of the stone marten being unique even at a European level; the prolonged high degree of frugivory indicates the perfect adaptability of the two native carnivore species.

Key words: dietary pattern, frugivory, Martes foina, trophic niche, Vulpes vulpes.

Title: Morphometric discrimination between age groups of Martes foina (Mustelidae, Carnivora) by using baculum in Turkey

Abstract: Martes foina has a wide range in Turkey. Identification of age groups in Stone Marten requires considerably hard procedures as well as in other carnivorous species. The present study is based on eight characteristic measurements from bacula of 41 samples obtained from all geographical regions of Turkey between 1995 and 2016. The goal is to discriminate young, juvenile, and adult individuals of Stone Marten using measured characteristics of the bacula. Analyzes revealed significant differences between young and adult samples. The characteristic, with the closest and lowest variability between age groups, is the total length of the baculum. The variation coefficient of this feature in young, juvenile, and adult individuals is 4.92%, 6.73%, and 3.90%, respectively. By using Linear Discriminant Analysis, juveniles were discriminated by 94.1% and adults by 95.5%. The samples which were ordered by describing with respect to the morphology of skull and shape and size of baculum at the beginning were grouped as 2 youngs, 17 juvenile individuals, and 22 adult individuals as a result of the analysis. Two baculum index, BI and BInew, were calculated for age groups. The indices were coherent. BI values of the adults were <6.65;7.78> and within the standards of the Italian population.

Key words: Stone Marten, os penis, morphometric analysis, mustelids.

Title: Ecological aspects of Red Squirrel (Sciurus vulgaris) dreys in city parks

Abstract: Modified habitats often pose challenges to native fauna. Red Squirrels (Sciurus vulgaris) successfully inhabits territory of the cities. However research on quite abundant Red Squirrel populations in urban parks of Lithuania was lacking. The investigation was carried out in two city parks (area of Giruliai park 152 ha, Pasakų park forest – 31 ha) in Vilnius, Lithuania. Both areas were mainly coniferous, dominated with pine (Pinus sylvestris). Drey (N = 415) counts were done in February and March 2014–2016. Dreys were found in eight tree species. The Red Squirrels’ dreys were mainly built in most widespread tree species: pine (84.8% of all dreys) and birch (8.1%). Most of the found dreys were built on the side branches at the stem (47.7%). 21.8% of the dreys were built on the branches further from the stem, 18.5% on the top branches and 12% in the stem fork-off. Most of the dreys were set in the southern exposition (33.9%). Average number of red squirrels in both parks in 2014–2016 was 0.20±0.01 squirrels/ha, the average number of dreys – 0.75±0.05 dreys/ha. The population of urban red squirrels in Vilnius city parks can be regarded as stable and having medium abundance, which is supported by supplementary feeding.

Key words: Sciurus vulgaris, dreys, urban ecology, urban parks, habitat.
