Abstract: The earthworm tribus Neogastrini is reviewed. On the basis of the calciferous glands" opening the two African Pickfordia (Omodeoscolex) species are separated in a new genus Afrogaster gen. nov. From the collection of the Natural History Museum, London a new Neogastrini species representing a new genus Pickfordiella eudrilina gen. et sp. n. is described. A key to the Paleotropical Neogastrini species is given.

Title: Development and morphology of Unduloribates undulatus (Berlese, 1914) (Acari: Oribatida) and some remarks on the Unduloribatidae

Authors: Pfingstl, T. and Krisper, G.

Authors' address: Institute of Zoology, Karl-Franzens University, Universitätsplatz 2, A-8010 Graz, Austria, E-mail: guenther.krisper@uni-graz.at

Abstract: Unduloribates undulatus, a moss-dwelling species living in alpine habitats of the European Alps, the Sudeten mountain range (Giant Mountains), and the Carpathians, is redescribed in detail and information on the ontogenetic development is given. The species-specific characteristics are ten pairs of long and spiniform notogastral setae, long and spinose interlamellar setae, a slender, longish lenticulus and the juveniles show a plicate integument, a lateral carinate opisthosomal dorsum, uniform short spiniform notogastral setae, keel-like lamellae and femoral porose areas. The comparison with U. brevisetosus, U. dianae, U. hebes and U. medusa showed clear separation of all species. Koreoribates, the second genus of Unduloribatidae, is a junior synonym of Unduloribates, as the described characters of its only species, K. foliatus, well fit the known range of traits in the latter genus.

Abstract: We studied sexual size dimorphism (SSD) in captive house mice derived from free-living commensal (inhabitants of buildings and stores) and non-commensal (field and/or semidesert dwellers) populations. While females of commensal populations and most strains of laboratory mice are more or less tolerant to each other, females from non-commensal populations are as highly aggressive as their male conspecifics. As body size considerably contributes to fighting success, we addressed the question whether sexual size dimorphism in commensal mice, with larger males, can be attributed to the switch to the commensal way of life. For this purpose, we performed a laboratory common garden experiment in which non-commensal populations of Mus musculus domesticus from Jordan and SW Iran were compared with Greek commensal mice belonging to the same subspecies. M. m. musculus and natural hybrids of these subspecies from the Czech Republic were also included. Growth was recorded for 102 litters and 592 juveniles born during the experiments, and SSD calculated on the basis of within litter comparisons between the sexes. Males were considerably larger (SSD = 1.05) at the age of 35 days. Newborn males tended to be larger than newborn females but this tendency rapidly disappeared during the early postnatal period. Starting from a nearly monomorphic state at the age of two weeks, size difference between the sexes was established gradually up to the end of the experimental period. We found no significant differences in SSD among the studied populations at any age. Hence, we suppose that the present SSD in the house mouse could be explained by selective forces operating in the non-commensal way of life, which is ancestral with respect to the commensal one.

Title: Intraspecific genetic variation and phylogeography of the oak gallwasp Andricus caputmedusae (Hymenoptera: Cynipidae): effects of the Anatolian Diagonal

Author: Mutun, S.

Abstract: Physical barriers and major climatic oscillations in the Pleistocene are of enormous importance for the distribution and current population genetic structure of many animal taxa. Anatolia was one of the main corridors for postglacial colonization of Europe and it is characterized by rich biodiversity. In the present study, mitochondrial DNA (mtDNA) RFLPs were used to assess i) the phylogeographic relationships among 26 populations of an oak gallwasp, Andricus caputmedusae, and ii) the impact of the heterogenous topography on the geographic structure of populations. PCR was used to amplify a ca. 2540 base pair mtDNA region spanning the genes ND4, ND4L, tRNAThr, tRNAPro, ND6 and part of cytochrome b. Digestion of this region with eight restriction enzymes yielded a total of 31 haplotypes that divided sampled populations into three phylogenetic assemblages reflecting their geographic location. The average haplotype and nucleotide diversities within populations were 0.4631 and 0.101214, respectively. AMOVA analysis attributed high levels of genetic variation to variation within <%-1>populations (31.26%), variation within groups (24.85%), and variation among groups (43.89%).<%0> Estimation of the age of divergence between mitochondrial lineages with reference to the geological history of Anatolia suggests that the current population structure of A. caputmedusae was shaped by both the Pleistocene climatic fluctuations and the heterogenous topography of Anatolia.

Abstract: Marsh harrier (Circus aeruginosus) populations have declined dramatically in China for a variety of reasons, in particular habitat destruction. In order to better understand this key protected species in its overwintering area, we conducted a-four-year investigation of marsh harrier habitat preference and prey selection in the Shahu Nature Reserve, an area of low human population density. Of the four habitats monitored, grassland was the first choice for marsh harrier despite the presence of grazing cattle, with both the highest mean rank and lowest coefficient of variation. The abundances of the two prey types (common pheasant and passerine birds) varied significantly in different habitats, and the regression relationships between marsh harrier and the two prey types in different habitats were completely independent of each other. The habitat preference of the marsh harrier associated with both prey types was influenced not only by habitat type, but also by habitat structure. The type and abundance of prey varied with different habitat types and structures, but the abundance of marsh harrier did not change accordingly.

Abstract: Reproductive success of raptor species is significantly affected by the quantity and/or quality of available prey. In our study we analysed prey composition of breeding imperial eagles (Aquila heliaca) in East Hungary, where 434 nesting events in 81 different territories had been monitored between 1995 and 2004. We identified 1297 prey items originating from 43 bird and 16 mammalian species (532 and 764 specimens, respectively). Three prey species, the brown hare (Lepus europaeus), the hamster (Cricetus cricetus) and the pheasant (Phasianus colchicus), seem to have especially important role in the diet of imperial eagles in Hungary, although their relative frequencies varied greatly among different regions. We found that eagles were less productive in a region where hamster was the main prey (West Zemplén Mts) as compared to a recently colonized hare-dominated region (Heves Plain), suggesting that hares may provide a better food source than hamsters. The increase of game species in the diet of imperial eagles could generate hostility in hunters. Possible conflict between nature conservation and small-game management may be resolved by raising public awareness and by common projects to improve hare and pheasant habitats.
