Bottom Rock

The shallow water zone (0–10 ft.) of Meach Lake provides three types of bottom:— rock, sand and mud. Certain species of mollusca live in all three habitats, some in two and some in one. Seventeen species were found, two of which were confined to the drainage. Nine of the seventeen are recorded for Meach Lake for the first time. The number of species and the size of individuals are both smaller in the inlet and in the streams flowing into the lake than in the lake itself. A dwarfed fauna occurs at the outlet. One species has apparently disappeared from the lake in a period of two years.

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.

ABSTRACTTwenty-seven species assigned to 20 genera of trilobites are described from Feilaishi in Guizhou Province, the type section of the Shihtzupu Formation in S W China. They occur in association with a sparse graptolite fauna including Glyptograptus teretiusculus. Eleven taxa are recorded here for the first time. Much new morphological information is provided regarding previously known species and 3 lectotypes are selected. The trilobites are largely endemic and indicate a quiet and comparatively shallow water environment

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.

This study was carried out to determine the amphipod fauna in Mar Piccolo, Mar Grande and the Gulf of Taranto. Material in this study was obtained from 96 stations at different depths (maximum depth: −50 m) using various methods depending on the substrata. A total of 65 species was determined and 25 species are new records in the seas of Taranto. Microdeutopus gryllotalpa, Ericthonius brasiliensis, Monocorophium insidiosum, Elasmopus rapax, Gammarus aequicauda, Gammarus insensibilis, Leucothoe spinicarpa, Lysianassa costae and Pseudoprotella phasma were the dominant species and have been found in all areas considered. The comparison of the data shows that the area examined presents a high difference regarding biocenotic index. The highest number of species was collected in the Gulf with 1944 individuals, belonging to 58 species and 19 families, followed by Mar Grande with 1448 individuals belonging to 36 species and 11 families; finally Mar Piccolo with 698 individuals, 12 species and 6 families, in the First Inlet and 546 individuals, 18 species and 6 families, in the Second Inlet.

The molluscs of a previously unexplored site the “Ženklavský les” forest in North Moravia (Czech Republic) were investigated in 2002. Altogether 47 snail species were recorded (46 terrestrial and 1 aquatic). The molluscan fauna was dominated by woodland species including sensitive and endangered ones (e.g., Platyla polita, Sphyradium doliolum, Ruthenica filograna, Vitrea subrimata, and Daudebardia brevipes). The species Vertigo pusilla, and Vestia ranojevici moravica were encountered in the Štramberk environs for the first time and are of regional importance.

There are only a few published bat surveys from the southwestern Brazilian Amazon, but recent studies have reported additional bats species in the region. We provide the first list of bat species from Floresta Estadual do Antimary (Antimary State Forest) and record for the first time Glyphonycteris sylvestris Thomas, 1896 and Phylloderma stenops Peters, 1865 in the state of Acre, increasing to 64 the number of species known from this state. Our survey enlarges the known geographic range of G. sylvestris in Brazilian territory and improves the inventory of bat species in a poorly sampled region of the Amazon.

The Upper Barremian-Lower Aptian succession is recorded from a limestone sequence that crops out in the surrounding of Rakova Bara in the Carpatho-Balkanides range in northeastern Serbia. The micropalaeontological and sedimentological studies lead to recognition of the two types of microfacies. The benthic foraminiferal association consists of Vercorsella laurentii, Rumanoloculina robusta, Praechrysalidina infracretaceae, Dictyoconus gr. arabicus, Debarina hahounerensis, Charentia cuvilieri and Pseudocyclammina lituus that confirm the stratigraphical and palaeoenvironmental connection of the microfossil assemblages with the classical Urgonian-type, shallow-water carbonate sedimentation. The association documented for the first time in the study area is considered typical of the Tethyan Realm. The stratigraphical position of the benthic foraminifera species within the Upper Barremian-Lower Aptian interval is discussed. The Urgonian Limestone's of the studied section are comparable with adjacent areas of eastern Serbia and Romanian South Carpathians. .

Located in southwestern Maranhão, the Parque Nacional da Chapada das Mesas (PNCM), with an extent of about 160,046 ha, is completely inserted in the Cerrado phytogeographic domain. The topography is characterized by a plateau formation consisting of steep hills and medium-altitude mountains with flat tops, which give the PNCM its name. We present an annotated checklist of the mosses that occur in the PNCM. Our checklist includes 26 species of pleurocarpous mosses distributed in 10 families and 22 genera and two species of cladocarpous mosses of the family Orthotrichaceae. The most species-rich families of pleurocarpous mosses were Sematophyllaceae (7 spp.), Pylaisiadelphaceae (6 spp.), and Stereophyllaceae (4 spp.). Eleven species are recorded for the first time from Maranhão and three species are recorded for the first time in the northeast region of Brazil. Taxithelium pluripunctatum (Renauld & Cardot) W.R. Buck and Trichosteleum glaziovii (Hampe) W.R. Buck, are recorded for the first time from Maranhão and the Cerrado phytogeographic domain. Our results expand the knowledge of the Brazilian bryoflora and add distribution data for a number of species in Maranhão and the northeast region.
