The annelid community of a shallow Mediterranean lagoon (Gialova Lagoon, Ionian Sea) was studied on a seasonal basis. Out of the 39 species identified eight are reported for the first time from the central Mediterranean. The dominant species were the polychaetes Capitella capitata, Neodexiospira pseudocorrugata, Malacoceros fuliginosus, Perinereis cultrifera, Hediste diversicolor, Heteromastus filiformis and the oligochaete Limnodriloides maslinicensis. Uni- and multivariate methods were employed to study the community structure. The coenocline observed is strongly related to the degree of isolation; its main features (i.e. number of species, density, geometric abundance and size-classes) in space and time are presented and discussed in detail. The distribution pattern of the annelid community has been found to be governed by a different set of environmental factors in each season. Although this narrow lagoonal habitat suffers severe dystrophic episodes it manages to recover, demonstrating a seasonal community pattern.

We studied in detail a moss-lichen component of Shokalsky Island vegetation for the first time and identified 79 species of mosses and 54 species and 2 subspecies of lichens and lichenicolous fungi. All species of mosses and 23 species and 2 subspecies of lichens and lichenicolous fungi are recorded for the first time for the island. The study is based on collections made in South West part of the island, in arctic tundra. We also explored the participation of the mosses and lichens in the main types of plant communities and the species distribution in 10 ecotopes. The paper describes the noteworthy findings (Abrothallus parmeliarum, Aongstroemia longipes, Arthonia peltigerea, Caloplaca caesiorufella, Catillaria stereocaulorum, Ceratodon heterophyllus, Lecanora leptacinella, Sphagnum concinnum, S. olafii) and features of bryo- and lichenoflora of Shokalsky Island.

Taxonomy of some Central, Middle and South West Asian representatives of Lepidium s. l. is revised and updated. Poorly known taxon, L. rubtzovii, is shown to be unrelated to L. coronopifolium s. l., but close to L. lacerum. Three new combinations (L. lacerum subsp. rubtzovii, L. leventii, and L. macrocarpum) are proposed. The names L. deserti, L. persicum subsp. arianum and L. seravschanicum, and Stroganowia kazachstanica are newly recognized as synonyms of L. obtusum, L. ferganense, and L. cardiophyllum, respectively. For L. ferganense and L. macrocarpum, lectotypes are designated. Besides, L. lacerum subsp. rubtzovii is reported for the first time for China (instead of subsp. lacerum), L. leventii for Iran, L. macrocarpum for Tajikistan, and L. obtusum for Afghanistan. In contrast, occurrence of L. lacerum in Uzbekistan and Turkmenistan is considered doubtful.

Marx met the then 22 years old Blind) for the first time in May 1848, when he and Engels made their appearance in the revolutionary state of Baden (Germany), after the Neue Rheinische Zeitung had been suspended. At that time they declared to the members of the republican committee at Karlsruhe (Landesa usschuss), that they considered the revolt in the South-West of Germany irretrievably doomed to failure, if no decisive moves in Hungary or another revolution in Paris should come to its rescue. The only members of the committee who supported this opinion were, as stated by Engels), Karl Blind and Amand Gögg. Soon afterwards Marx and Blind met again in Paris. On September 5 Marx gave Blind's address to Freiligrath as his own. Blind had been sent to France by the revolutionary governments of Baden and the Palatinate as one of the members of the legation, which these two shortlived republics intended to establish there. But Louis Napoleon's government ignored this legation, and consequently did not respect Blind's diplomatic immunity, when the latter, soon after his arrival, proved to be involved in the abortive coup of Ledru-Rollin of June 13. Blind was placed under arrest and expelled from France on the same day, on the ground that his presence was “such as to disturb public order and calm”.

Abstract. Vertical structures of aerosol single scattering albedo (SSA), from near the surface through the free troposphere, have been estimated for the first time at distinct geographical locations over the Indian mainland and adjoining oceans, using in-situ measurements of aerosol scattering and absorption coefficients aboard the FAAM BAe-146 aircraft during the South West Asian Aerosol Monsoon Interactions (SWAAMI) campaign from June to July 2016. These are used to examine the spatial variation of SSA profiles and also to characterize its transformation from just prior to the onset of Indian Summer Monsoon (June 2016) to its active phase (July 2016). Very strong aerosol absorption, with SSA values as low as 0.7, persisted in the lower altitudes (

Abstract ‘Paraphiomys’ simonsi is a phiomorph rodent from the early Oligocene of Egypt (~29–30 Mya) that has historically been aligned with much younger (< ~20 Mya) Miocene species of the genera Paraphiomys and Neosciuromys. Here, we use Bayesian tip-dating analysis of a 109-character morphological matrix containing 57 living and extinct ctenohystricans to test these proposed placements for ‘Paraphiomys’ simonsi. Our analyses provide support for the exclusion of ‘Paraphiomys’ simonsi from both Paraphiomys and Neosciuromys and justify the establishment of a new genus (Monamys gen. nov.) for this stem thryonomyoid. These analyses also indicate that the divergence of the extant dassie rat Petromus from the extant cane rat Thryonomys (i.e. origin of crown Thryonomyoidea) occurred ~23.7 Mya, close to the Oligocene–Miocene boundary and in close agreement with recent molecular estimates for this split. Miocene Neosciuromys, Paraulacodus, Protohummus and the type species of Paraphiomys are identified as stem thryonomyids, whereas the Namibian species Apodecter stromeri, Tufamys woodi, ‘Paraphiomys’ australis and ‘Paraphiomys’ roessneri are identified for the first time as stem petromurids, raising the possibility of a long period of endemic petromurid evolution in south-west Africa. Comparison of molecular divergence estimates with our optimal tip-dated topology suggests that stem bathyergoids are most likely to have arisen from late Eocene and early Oligocene ‘phiomyids’.

Abstract A specific study has been carried out for the first time to investigate the homing capability and daily home range of the spiny lobster Palinurus elephas by means of ultrasonic telemetry. Nine lobsters collected in the Capo Gallo — Isola delle Femmine marine protected area (northwestern Sicily, central Mediterranean) were tagged with miniaturized transmitters and released at a single site inside the protected area. The lobsters were monitored with the purpose of calculating their horizontal and vertical positions, analysing their movement patterns to assess their homing capability, and calculating their daily home range. Five lobsters moved back close to the capture sites within the first 20 hours after release (‘homed’). The remaining four lobsters ‘relocated’ to a different refuge. Homed lobsters had a larger home range than relocated lobsters. This study provides the first description of a homing pattern with high spatial resolution in the wild European spiny lobster as inferred by ultrasonic telemetry.

Two vases, a cup and an oinochoe, from Arkesine in south-west Amorgos are published for the first time. It is argued that both are probably Middle Protogeometric, one an import from Euboia, the other from the south-east Aegean; chemical analysis supports both attributions. Their implications for the early history of Amorgos are discussed.

Gryllotalpa weisei Simeu-Noutchom & Kekeunou sp. nov. was collected only in Tombel in the South-West region of Cameroon, during a survey conducted from March 2016 to March 2018 in the West, South-West and Centre regions of Cameroon. This species is close to Gryllotalpa microptera, collected for the first time in Cameroon during these investigations, only in the West region. G. weisei is different from G. microptera due to the hind wings that are vestigial; average fore wings length of 5.85±0.56 mm in male and 5.34±0.45 mm in female, not reaching the fifth abdominal segment; anal end of fore wings slightly concave; a stridulatory file with 54±8.02 teeth (47–71) in average, fairly spaced, with an average of 30±5.06 teeth per millimeter; hind tibia bearing 11 spines; internal process of ectophallus quite short. G. weisei abounds in mixed crop fields, followed by cocoa agro-forests; it is scarce in grassy fallows and in forest undergrowth. G. microptera was present in all types of vegetations in Bafoussam, Babeté and Bangoulap in the West region where it has been abundant in mixed crop fields, grass-fallow and coffee agro-forest but rare in forest undergrowth.

ABSTRACTA magnetometry survey of the Roman fort at Lake Farm, near Wimborne Minster in Dorset, first discovered in 1959, has upgraded the status of this site to a full legionary fortress: a major base of the legio II Augusta during the subjugation of the Durotriges and other tribes of south-west Britain. The interior layout of the fortress was identified for the first time, together with the original road and river connections, extensive areas of extramural activity and evidence for an earlier phase of the site as a marching camp.
