The distribution of stone crayfish Austropotamobius torrentium (Schrank, 1803) (Crustacea: Decapoda: Astacidae) in the south-west Romanian mountain and sub-mountain area Data is presented in relation to the geographical distribution of the endangered crayfish species Austropotamobius torrentium. One hundred and seventy-four sampling stations situated along the streams of 15 geographical units from the South-West of Romania (Anina Mountains, Almăj, Dognecea, Godeanu, Locva, Ţarcu, Retezat, Semenic, Mehedinţi, Vâlcan, Parâng, Şureanu, Poiana Ruscă, Lipova Hills and Mehedinţi Plateau) have been investigated. A distribution map was compiled. The data from older publications were collated. The actual habitat of this species occupies a large area of South-West Romania in the mountain and sub-mountain area, being absent in the Poiana Ruscă Mts, Lipova and Dognecea Hills.

Abstract Currently, little information is available about the orchid flora in the “Iron Gates” Nature Park, especially due to the lack of the data regarding the detailed geographical distribution and the actual conservation status of species and populations. According to the data provided by the specialist literature for the south-west of Romania, 39 species of orchids are found in this area, of which 29 are in the Danube Gorge (known as Clisura Dunării ‒ “Iron Gates” Nature Park). The field researches regarding the Orchidaceae L. family in the “Iron Gates” Nature Park area have been conducted over a period covering 15 years, from 1996 to 2011. During research conducted in the field I acknowledged the presence of 23 orchid species in the Danube Gorge area and ascertained the presence of new orchid species in the research area: two new species in the Danube Gorge area (“Iron Gates” Nature Park): Epipactis purpurata Sm. and Listera ovata (L.)

Based on nearly 2000 available records, the broadscale geographical distribution of the native earthworm fauna of Australia was mapped. Native earthworms were recorded from south-eastern, eastern and northern Australia within 400 km of the coast. Isolated faunas were present in Tasmania and south-west Western Australia, and apparently isolated faunas occurred in the Adelaide area/Fleurieu Peninsula of South Australia and the ranges of central Australia. All but 30 locality records occurred where annual rainfall averaged or exceeded 400 mm; 16 of these records were instances of moisture-gaining sites (moist caves, waterholes, banks of large rivers, edge of granite domes). A collecting strategy to both fill in gaps in the distribution map and discover additional anomalous occurrences (with respect to the 400 mm isohyet) is outlined.

ABSTRACT The aim of the present work has been to verify the determining influence of the environmental factor on the geographical distribution of goitre in Idjwi Island (Lake Kivu, Dem. Rep. of the Congo). The weight and histology of the thyroid of wild rats have been compared in the areas of high (North Idjwi) and low (South West Idjwi) prevalence of goitre in man. This animal has been chosen because its food consists mainly of the remains of human food and because it abounds in the two areas investigated. The mean thyroid weight in 114 rats captured in the North of the Island is 18.3 ± 0.5 mg. This result is significantly higher than the value of 12.1 ± 0.3 mg obtained in 101 animals captured in the South West of the Island (P < 0.001). Furthermore, an aspect of hyperstimulation characterized by a reduction or disappearance of the colloid of the thyroid vesicles was observed in 66.7% of the glands in the first area, as compared to 8.5% only in those of the second area (P < 0.0005). This investigation thus shows the existence of a goitrous enzootic in the wild rat in Idjwi Island, which is geographically superimposable on the endemic human goitre. Since the North and the South West of the Island have a similar iodine deficiency, the present data support the hypothesis of the existence in the North of the Island of an additional goitrogenic factor, distinct from the iodine deficiency.

Printed Sources

In the following paper an attempt has been made to bring together scattered notices from printed sources regarding the geographical distribution of the Bektashi sect, as indicated by the position of existing or formerly existing convents of the order. I have further included such information on this subject as I have been able to obtain from my own journeys and enquiries (1913–15) among the Bektashi: nearly all this information is gathered from Bektashi sources, and much from more than one such source. I hope to have made a fairly complete record of Bektashi establishments in Albania, now the most important sphere of their activities, and a substantial basis for further enquiry in the other countries where the sect is to be found, with the exception of Asia Minor, for which my sources are at present inadequate.From the evidence at our disposal the Bektashi establishments in Asia Minor would seem to be grouped most thickly in the ‘Kyzylbash’ or Shia Mahommedan districts, especially in (1) the vilayets of Angora and Sivas, and (2) in the south-west corner (Lycia) of that of Konia, where the Shia tribes are known from their occupation as Tachtadji (‘wood-cutters’). For the third great stronghold of Anatolian Shias, the Kurdish vilayets of Kharput and Erzeroum, no information as to Bektashi tekkes is available.

The Hill

From the southern shores of Dublin Bay there stretches to the south-west a broad granite intrusion with rocks of supposed Ordovician age on both sides of it. These rocks are metamorphosed near the granite, and the belt of metamorphism is wider on the south-east than on the north-west side, indicating, no doubt, that the plane of junction dips more steeply on the latter side. Near Dublin the Lower Carboniferous rocks rest unaltered upon the granite. On the south-east side, in the northern part of the county of Wicklow, the belt of Ordovician rocks is only some 2 miles wide, and a large area of supposed Cambrian rocks lies between it and the sea. Around the hill of Carrickgollogan a. patch of similar rocks appears incongruously in the middle of the Ordovician belt. After a study of the region to the south of Dublin one seems to be naturally drawn towards this small area around Carrickgollogan, for it presents a problem, the key to which may explain the geological structure of a much wider area.

AbstractIn contrast with the usual coloration of stone crayfish (Austropotamobius torrentium), we newly discovered a rare marble morph in a brook in the Czech Republic (Central Europe). During mark-recapture sessions, we captured by hand 1,103 individuals over the 3 years 2008–2010 from which only 5 were marble-colored. This color morph’s frequency of occurrence was thus less than 1% within the estimated subadult and adult stone crayfish population. Although many biological papers and determination keys regarding crayfish are based upon analysis of exoskeletal coloration, recent studies have asserted that this characteristic provides unreliable guidance when determining species inasmuch as it easily results in errors because many crayfish species exhibit an extensive variety of color morphs.

Svartenhuk Halvø is built up primarily of Tertiary basalts; these overlie Cretaceous and early Tertiary sediments, and overlap onto the Precambrian basement. The basalt series can be divided into a lower and an upper series; although displaced by faults, the boundary between these series can be followed across the peninsula. The thickness of the lower basalt series is estimated to be about 2-3 km in the south of the peninsula and barely 1 km in the north; the sub-aquatic basalt breccia is included in these thicknesses. FauIts causing repetitions of the lava succession have resulted in the series being preserved over a rather large area. The general dip of the lavas is 3-4 dregrees towards SW in the east and 8-10 degrees, also towards SW, in the west. Locally dips between 10 and 20 degrees or even steeper are seen; these are the resulf of drag along fault zones in Arfertuarssuk fjord and Kugssineq valley, and between Svartenhuk Halvø and Ubekendt Ejland. The youngest fault has a displacement of 500 m or more and has downthrown the basement area to the north-east in relation to the sediment-basalt breccia-basalt series to the south-west. The upper basalt series has by far the greater lateral extent and covers the gneiss and metasediment area to the north and north-east at least as far as the Inland lee. The dip of the flows in this part of the basalt series is considerably lower than in much of the lower basalt series, but faults repeating the succession are also frequently encountered within the upper basalts. The tectonic movements evidence a strong E-W (or NE-SW) tension, never a compression; the weak anticlinal and synclinal structures which are seen are interpreted as resulfing from differential sagging. The lower basalt series is thought to have arisen from fissure eruptions, with the main area of eruption in the east. The lavas are very rich in olivine (i. e. are pieritic). The upper basalt series probably arose from central eruptions and smaller fissure eruptions, and the area of eruption is thought to have shifted to the west. The upper lavas become poorer in olivine; andesitic lavas represent perhaps a closing phase, more local in its distribution and perhaps resulting from magmatic assimilation of pre-basaltic sediments. "Iron basalt" and intrabasaltic breccia have not been noted on Svartenhuk Halvø.

The object of the present communication is to place on record a section, apparently unique, in which the unconformity between the Millstone Grit and Carboniferous Limestone that exists in parts of South Wales and Monmouthshire is clearly displayed. The exposure was first examined at the suggestion of the brilliant worker who threw so much light on Lower Carboniferous problems, the late Dr. Vaughan. The writer had explained1 the attenuation of the Carboniferous Limestone Series in the Newport (Mon.) district as due to unconformable overstep by the Millstone Grit, similar to an overstep at this horizon that had already been observed near Haverfordwest, at the other end of the South Wales basin, by Professor O. T. Jones.1 The value of the Ifton section in demonstrating that this overstep was widespread was recognized, and photographs, two of which are here reproduced, were secured by H.M. Geological Survey. Since then the unconformity at the eastern end of the South Wales coalfield has been confirmed by the detailed examination of a large area by Mr. F. Dixey and Dr. T. F. Sibly,2 and has been found by the writer, in the course of work not yet published, to reach its greatest known extent in the Abergavenny district. Nevertheless, it seems desirable to describe the Ifton section because it is the clearest exposure known, in the whole of the South-West Province, of the unconformity between the Carboniferous Limestone and the Millstone Grit, and also on account of the remarkable inter-relations of the two formations which it reveals.
