Results from collections of oribatid mites in the cushion plant belt of Sass Pordoi and Piz Boè in the Italian Dolomites (Prov. Trento) are presented. A total of 10 oribatid species belonging to seven families were found. Most have a wide general distribution, Anachipteria shtanchaevae is restricted to the Alps. Three species are frequently or mainly found in the montane to alpine zone (A. shtanchaevae, Camisia horrida, Oribatula interrupta). Remarkable findings are Camisia foveolata, hitherto only known from the boreal climate zone, which indicates a preglacial relict distribution, and Kunstidamaeus lengersdorfi as highest recorded altitude for this species. Trichoribates valeriae n. sp., found in large numbers on both mountains, is described and compared with other congeners, and its systematic position is discussed. This species is characterized by a lamellar structure with small ridges and widely separated cusps, rounded rostrum with nose-like protuberance, 10 pairs of medium long notogastral setae with short bristles, notogastral porose area A1 divided in two parts, porose areas present on all tibiae and tarsi. Additional morphological information on the presence of porose areas on tarsi of Trichoribates scilierensis Bayartogtokh and Schatz, 2008 is given.

A checklist of the oribatid mites from Vorarlberg (Austria) which covers all published records and hitherto unpublished results of additional collecting is presented. Several species are revised, doubtful and erroneous records from previous publications are discussed and corrected. At present a total of 327 described species are known from Vorarlberg, complemented by three subspecific taxa and two undetermined or undescribed species, altogether from 61 families. A total of 96 species (including 3 subspecific taxa) are newly reported from Vorarlberg, among them 16 species are new records for Austria. The compilation includes the occurrence of each species in different vegetation units and habitats of Vorarlberg, their known distribution in Austria and the neighbouring Alps, Switzerland and Southern Germany, as well as their general distribution. Occasional additional remarks give taxonomic and other information. A historical overview of the exploration of the oribatid mites in Vorarlberg is outlined. The general distribution of the oribatid mite fauna of Vorarlberg is analysed. Remarkable results are, among others, the findings of some mostly rare species which were described by Schweizer and Mahunka & Mahunka-Papp from Switzerland as well as species restricted to the Alps, mainly in higher montane regions.

Three new species of oribatid mites of the family Galumnidae are described from soil and coniferous litter of Hogsback State Forest, Eastern Cape Province, South Africa. Pilogalumna hogsbackensis sp. nov. differs from Pilogalumna tenuiclava and P. ornatula by the presence of elongate oval postanal porose area and narrowly unilaterally dilated bothridial head. Pergalumna amatholensis sp. nov. differs from Pergalumna distincta by the presence of smaller body size, rounded rostrum, unilaterally dilated bothridial head, one pair of notogastral porose areas Aa, and the localization of opisthonotal gland opening and lyrifissure im. Stictozetes ihaguensis sp. nov. differs from all species of the genus by presence of bothridial seta with narrowly dilated head and median pore in both genders. An identification key to known species of Stictozetes is presented.

The xylem and phloem of Brassicaceae (116 and 82 species respectively) and the xylem of Resedaceae (8 species) from arid, subtropical and temperate regions in Western Europe and North America is described and analysed, compared with taxonomic classifications, and assigned to their ecological range. The xylem of different life forms (herbaceous plants, dwarf shrubs and shrubs) of both families consists of libriform fibres and short, narrow vessels that are 20–50 μm in diameter and have alternate vestured pits and simple perforations. The axial parenchyma is paratracheal and, in most species, the ray cells are exclusively upright or square. Very few Brassicaceae species have helical thickening on the vessel walls, and crystals in fibres. The xylem anatomy of Resedaceae is in general very similar to that of the Brassicaceae. Vestured pits occur only in one species of Resedaceae.Brassicaceae show clear ecological trends: annual rings are usually distinct, except in arid and subtropical lowland zones; semi-ring-porosity decreases from the alpine zone to the hill zone at lower altitude. Plants with numerous narrow vessels are mainly found in the alpine zone. Xylem without rays is mainly present in plants growing in the Alps, both at low and high altitudes. The reaction wood of the Brassicaceae consists primarily of thick-walled fibres, whereas that of the Resedaceae contains gelatinous fibres. The frequency of sclereids in Brassicaceae bark is an indicator of ecological differences: sclereids are rare in plants from the alpine zone and frequent in plants from all other ecotones.

This work consists of four parts—the first dealing with registrations of meteorological phenomena at the Colába Observatory during a period of twenty-seven years; the second with moderately full observations at five military stations in the Bombay Presidency during a period of nineteen years; and the third with large numbers of observations from civil hospitals and revenue stations, being those of selected registers extending over various periods from not less than a fortnight up to a number of years: in this part the phenomena treated are temperature of the ah, winds, and rainfall only; and the extent of territory to which the observations refer includes the whole of the Presidency, bind, and the western half of Rajputána. In the fourth part are discussed the general distribution (as regards both space and season) of temperature and rainfall, and the variations of the wind; first with respect simply to the physical geography of the country, and then in combination with certain theoretical views, the elucidation of which, by means of the dynamical theory of heat and the kinetic theory of gases, occupies much space. Nearly half the memoir is devoted to the work of the Colába Observatory, of the history of which a short sketch is given. The design of this part is to give a compendious account of the results of a long and continuous maintenance of the Observatory, both in the shape of numerical determinations of meteorological elements and of their periodical and other variations, and in throwing light by means of these upon the physical conditions and actions which give rise to the observed relations between different phenomena, and to the variation of these relations with time.

Abstract A criticism of the theory of embryonic precursory folding in the Alps, based on some examples from Helvetic, Pennine, and Prealpine zones in Switzerland and Savoy, France. The importance of Mesozoic flexures and faults is stressed, as well as the absence of any indications of tangential crustal movements before the Cretaceous and the presence of evidence proving the instability of the paleogeographic elements of the Alpine zone. The thick masses of Alpine schists are not mainly "comprehensive series," but deposits accumulated rapidly in a relatively brief period of time. The essential characteristic of the Alpine geosyncline was mobility rather than subsidence.


The Anglo-American Pike's Peak Expedition, 1911, of which we propose to give the scientific results, was planned by members of Oxford and Yale Universities, with the main object of making a thorough study of physiological adaptation to low atmospheric pressures. It was decided to make all the observations on Man, as the conditions of respiration and the blood changes can be studied more satisfactorily in man than in animals. It was also essential that the physiological conditions, apart from the reduced atmospheric pressure, should be normal as far as possible, and that the observations should be continued over a considerable period. After considering the advantages and disadvantages of making the experiments in the Alps, Andes, or Himalayas, we selected Pike’s Peak, Colorado, as it seemed preferable in several very important respects. The Peak is practically free from snow in sum m er: there is a substantial house on the summit, in which we were offered excellent accommodation; and a cogwheel railway which ascends the mountain afforded easy transport for apparatus and supplies, and communication with the scientific laboratories at Colorado College, Colorado Springs, only about 14 miles distant. A further advantage was that large numbers of people came up daily during the summer, and furnished ample opportunities for observing the symptoms of mountain sickness in unacclimatised persons, while several persons living on the summit, besides ourselves, were available for studying the effects of acclimatisation.

Two new species of oribatid mites of the genus Protoribates (Oribatida, Haplozetidae) are described based on adult specimens from China. Protoribates tibetensis sp. nov. differs from all representatives of the genus Protoribates by larger body size, long, thick and barbed notogastral setae and monodactylous legs. Protoribates sichuanensis sp. nov. differs from Protoribates magnus (Aoki, 1982) by smaller body size, ventroanteriorly rounded femora II, shorter ad1 and single porose area A1. Three known species of Protoribates, P. crassisetiger nipponicus Fujita, 1989, P. geonjiensis Choi, 1994, and P. oblongus (Ewing, 1909), are recorded in China for the first time. Two other known species, Protoribates cattienensis Ermilov & Anichkin, 2011 and Protoribates dentatus (Berlese, 1883), are recorded in mainland China for the first time. Supplementary morphological information is given for all the above known species. A key to the Chinese species of the genus Protoribates is given.
