A total of 320 species from 42 families were registered in the herpetobios (stratobiont and epigeobiont beetles) of the urbocenosis of Kharkiv. Among these more than 160 species are recorded for the first time for this metropolis. Four species of ground beetles (Notiophilus germinyi Fauvel, Clivina fossor L., Laemostenus terricola Herbst and Masoreus wetterhali Gyll.) were not listed for Ukraine in the Catalogue of Palearctic Coleoptera. The species Omosita japonica Reitter, 1874 (Nitidulidae) is new for Ukranian fauna. Moreover, 93 species from 17 families are the dominant species (at least in one of the urban ecosystems). Among these, eudominants are represented with almost 20 species, but the number of eudomonants did not exceed ten species in separate urban cenoses. Carabidae (80), Staphylinidae (36), Curculionidae (32) and Tenebrionidae (8 species) dominate both, in species composition and abundance. The total part of these groups reached at least 90% of Coleoptera, recorded in urban-cenosis. Separate species of Silphidae, Dermestidae, Elateridae, Chrysomelidae, Leiodidae, Coccinellidae, Nitidulidae, Scarabaeidae, Histeridae and Lucanidae were sporadically usual in most plots. They accounted almost 9% of the total quantity of all beetles in transformed cenoses. Among these, a greater number of species are found within the families of Scarabaeidae (33), Chrysomelidae (16), Elateridae (14), Histeridae (12), Coccinellidae (11) and Nitidulidae (11), Silphidae (6) and Dermestidae (6). The rest of the families are represented with 1–4 species. All beetles registered in herpetobios belong to three groups. Typical inhabitants of herpetobios prevailed (about 200 species from 22 families, at least 90% of all Coleoptera). The proportion of species sporadically associated with herpetobios (more than 40 species from 10 families) was about 5% of all beetles. Random components of herpetobios are represented by more than 70 species from 10 families, and their total share did not exceed 3% of all Coleoptera. A preliminary taxonomic review of coleopterofauna was carried out in different urbocenoses. The number of species in urbocenosises ranged from 101 (Forest Park) to 124 (urban parks). In other green plantings of the city, the species diversity reached 105–118 species. The number of dominant beetles in different areas ranged from 37 to 60 species.

In this study we assessed, for the first time, grazing by Serrasalmus brandtii outside its natural range. We observed higher grazing proportions in samples from sites where S. brandtii is the dominant species in relation to sites where it is recorded as present and sites where it is absent. S. brandtii grazed preferentially on caudal fins in relation to all other fins alone or combined. It also preferred to mutilate fins instead of flesh. Larger fish had a higher probability of being mutilated and had a higher number of mutilated fins than smaller fish, which is expected as large fish represent a larger resource to their consumers. S. brandtii avoided mutilating conspecifics and, as its abundance increased, so did the number of species being preferentially grazed.

An annotated checklist of the mantis shrimps (Stomatopoda) occurring in India is compiled from published literature and specimens collected from coastal areas of Gujarat state. A total of 72 species, 35 genera, 10 families and 5 superfamilies reported from Indian waters are listed. Four species were recorded for the first time from Gujarat while one species, Erugosquilla hesperia (Manning, 1968), is confirmed for the first time from India. The maximum number of species was reported from Tamil Nadu (48 species), while fewest species were reported from Karnataka (2 species). The results also suggest that the east coast is more diverse (66 species) than the west coast of India (32 species).

Ten stations were sampled in the shallow-water sand habitat of Strangford Lough using a naturalist's dredge. Sediment samples were analysed to determine median diameter (ranging from 1·13 to 3·23 ø), Phi quartile deviation (ranging from 0·17 to 0·65 ø) and Phi quartile skewness (ranging from –0·11 to –0·04 ø).Twenty-two species of amphipod belonging to thirteen families were identified; ten species were new records for Strangford Lough and the Family Phoxocephalidae was recorded for the first time. The average number of species per station was nine and average abundance was 660 amphipods per station. The most frequently occurring species was the caprellid Phtisica marina (present in 90% of the samples); the overall dominant species was the corophiid Corophium crassicorne representing 52% of all specimens recorded.

Extended Range

Eastern Ghats are discontinuous hill ranges passing through Orissa, Andhra Pradesh and Tamil Nadu located between 11⁰30' & 22⁰N latitude and 76⁰50' & 86⁰30'E longitude. Bryophyte flora of this region is still very less explored. During a recent field exploration to Eastern Ghats region of Tamil Nadu three moss taxa viz. Solmsiella biseriata (Austin) Steere, Aulacopilum glaucam Wilson and Groutiella tomentosa (Hornsch) Wijk & Marg. have been identified as new additions to moss flora of Eastern Ghats. The present study provides the information regarding extended range of distribution of these taxa in India and a compensable account of morpho-taxonomical details with earlier described taxa from other bryogeographical zones.

AbstractIn 2001–2007, altogether 57 nests of lesser spotted eagle were collected in the Orava region in northwestern Slovakia and four groups of arthropods were extracted from them. Richest in number of species and individuals were mites (23 species, 17,500 ind.), followed by beetles (12 species, 725 ind.), whereas pseudoscorpions were represented only by Pselaphochernes scorpioides (39 ind.) and fleas by Ceratophyllus garei (3 ind.). Unlike nests of other birds, free-living mites predominated in the nests fauna (83% of individuals), followed by nidicolous species with more or less free relationship to the nests, while parasitic species represented only a negligible part of the fauna. For the first time we observed phoresy of Nenteria pandioni, a specific and abundant mite in the eagles’ nests, on the nidicolous staphylinid Haploglossa puncticollis. The beetle fauna in the nests was much poorer than in nests of other birds. The predatory H. puncticollis was dominant in the nests (83%) and occurred continuously during the whole investigation period. Other beetles, even the widely distributed nidicols such as the histerid Gnathoncus buyssoni, were found rarely in nests. Predators were also the only abundant trophic group of beetles in the nests, while other trophic groups of beetles abundantly co-occur in nests of majority of other birds. The occurrence of all beetles was very unevenly distributed during the investigation period, but was positively correlated with occurrence of mites. The relatively low number of species and individuals of mites and beetles in the lesser spotted eagle nests resulted from their position on tree tops, at a height of 20–30 m and their quick drying out by sun and wind. It was also indicated by an enormously low number of species and individuals of mycetophagous beetles, which represent a significant component of the fauna in nests of other birds.

In the study on the diversity and community structure of Ephemeroptera in the freshwater stream of Chinnasuruli falls on Megamalai hills, a total of 523 specimens belonging to thirteen genera and five families were collected in six month periods. Of the five families, Teloganodidae and Leptophlebiidae exhibited high diversity and Caenidae showed low diversity. Choroterpes alagarensis (Leptophlebiidae) is the most dominant species. Diversity indices such as Shannon and Simpson indices showed that diversity was maximum in November and December and it was minimum in August and January. Canonical Correspondence Analysis revealed that rainfall, water flow, turbidity, and air temperature were the major stressors in affecting the Ephemeropteran community structure.
