The collection of adults, mature male pupae, and the absence of confusing species at the sampling sites located in the Cevennes and French Alps enabled descriptions of the hitherto unknown larvae of Plectrocnemia cevennensis Coppa 2011 and P. praestans McLachlan 1884 (Trichoptera, Polycentropodidae). We present information on the morphology of the larvae and illustrate the most important diagnostic features. In the context of the larval key to European Plectrocnemia species by Waringer & Graf (2020), P. cevennensis keys together with P. scruposa McLachlan 1880, whereas P. praestans keys with P. conspersa (Curtis 1834). These two species pairs are morphologically very close; P. cevennensis and P. scruposa can be separated by the numbers of secondary setae on the last abdominal sternum, but the separation of P. praestans and P. conspersa is not always possible.

Sempervivum guillemotii (Crassulaceae) was discovered and described by Martial Lamotte in the French Alps, but apart from Rouy & Camus, it was never cited in the French floras. Burnat later rediscovered it, but unaware of Lamotte’s name, he published it under the name S. adenotrichum; this name, too, did not find its way into the floras until the recent Flora Gallica. The author rehabilitates this name and designates a neotype for the name S. guillemotii and a lectotype for its synonym S. adenotrichum.

This synoptic paper is intended to summarize and supplement the information available on the larvae of Thremma McLachlan 1876 in Europe. We present information on the morphology of the larvae and illustrate the most important diagnostic features. This information is used for the construction of a comprehensive discriminatory matrix for the four European species of family Thremmatidae Martynov 1935 known in the larval stage so far. In the context of this matrix, larvae can be easily diagnosed by the shape of mesonotal sclerites, foretrochantins, forefemora and ventral sclerites on abdominal segment I, by head coloration patterns, by case morphology, and by distribution. In addition, ecological characteristics and distributions of the European taxa are briefly discussed.

This synoptic paper gives descriptions of the hitherto unknown or poorly known larvae of Helicopsyche megalochari Malicky 1974 and H. revelieri McLachlan 1884 (Trichoptera: Helicopsychidae). We present information on the morphology of the larvae and illustrate the most important diagnostic features. This information is used for the construction of a comprehensive larval key to the five European species of family Helicopsychidae. In the context of this key, larvae can be easily diagnosed by setation patterns of the dorsal head capsule, submentum shape, and propleuron morphology. With respect to distribution, Helicopsyche megalochari has been reported from the Greek Islands of Andros, Euboea, Ikaria, and Naxos whereas H. revelieri is known from the islands of Capraia, Corsica, and Sardinia. In addition, ecological characteristics and distributions of the European species are briefly discussed.

The caddisfly Drusus dudor Oláh, 2017 (Limephilidae: Drusinae) was described from the Northwestern Italian Alps. We provide a detailed description of the larva, based on material from the Italian Province of Piemonte. Information on the morphology of the 5th larval instar is given, and the most important diagnostic features are illustrated. The larva is included in an updated key to larval Drusinae where D. dudor keys together with Drusus aprutiensis Moretti, 1981, D. camerinus Moretti, 1981, D. croaticus Marinkovic-Gospodnetic, 1971, D. mixtus (Pictet, 1834), and D. nigrescens Meyer-Duer, 1875. The species can be reliably separated by the morphology of the pronotum, the shape of the metanotal sclerites, and by morphological details of abdominal sternum I.

Coloration Patterns

Final instar larvae collected in the Rißbach (Isar catchment, Bavaria) were positively associated with adults of Rhyacophila albardana by barcoding; final instar larvae and adults of this species also were collected at the same time and site in the Lech River (Austria) in the absence of confusing species. These collections and associations enabled a description of the hitherto unknown larva of this species. We present information on the morphology of the larva and illustrate the most important diagnostic features. This dataset is included in a discriminatory matrix of the other larvae with comb-shaped gills (Rhyacophila Hyperrhyacophila Group) known so far from Austria, Germany, and Switzerland. Species can be separated by coloration patterns of the head and prosternum morphology. Rhyacophila albardana is known from Austria, France, Germany, Italy, and Switzerland (Neu et al. 2018).

The collection of adults and larvae sampled at the same site on Sicily and the absence of confusing species at the sampling location enabled a description of the hitherto unknown larva of Rhyacophila hartigi Malicky 1971 (Trichoptera: Rhyacophilidae). We present information on the morphology of the larva and illustrate the most important diagnostic features. This dataset is included in a discriminatory matrix of the ten other Rhyacophila larvae with tufted multifilament gills of Italy described so far. Species can be separated by coloration patterns of head and pronotum, and by anal claw morphology; however, separation of the R. dorsalis-palmeni-simulatrix-vulgaris species quartet is not yet possible. Rhyacophila hartigi is restricted to the southern Apennine Peninsula and the island of Sicily (Cianficconi et al. 2008).

Biochemical Analyses

Thirty-three mature male Holtzman rats were randomly placed in 3 treatment groups: Controls (C); Ethanolics (E); and Wine drinkers (W). The animals were fed synthetic diets (Lieber type) with ethanol or wine substituted isocalorically for carbohydrates in the diet of E and W groups, respectively. W received a volume of wine which provided the same gram quantity of alcohol consumed by E. The animals were sacrificed by decapitation after 6 weeks and the livers processed for quantitative triglycerides (T3), proteins, malic enzyme activity (MEA), light microscopy (LM) and electron microscopy (EM). Morphometric analysis of randomly selected LM and EM micrographs was performed to determine organellar changes in centrilobular (CV) and periportal (PV) regions of the liver. This analysis (Table 1) showed that hepatocytes from E were larger than those in C and W groups. Smooth endoplasmic reticulum decreased in E and increased in W compared to C values.

Present Information

If the resolving power of a scanning electron microscope can be improved until it is comparable to that of a conventional microscope, it would serve as a valuable additional tool in many investigations.The salient feature of scanning microscopes is that the image-forming process takes place before the electrons strike the specimen. This means that several different detection systems can be employed in order to present information about the specimen. In our own particular work we have concentrated on the use of energy loss information in the beam which is transmitted through the specimen, but there are also numerous other possibilities (such as secondary emission, generation of X-rays, and cathode luminescence).Another difference between the pictures one would obtain from the scanning microscope and those obtained from a conventional microscope is that the diffraction phenomena are totally different. The only diffraction phenomena which would be seen in the scanning microscope are those which exist in the beam itself, and not those produced by the specimen.

As a humanitarian worker who was professionally involved for decades in crisis- and war-shaken countries, the author strove to understand the political, socioeconomic, and cultural factors contributing to conflicts. This contextualization, with a focus on Arab countries, confirmed what other thinkers found: the majority of political, economic, social, cultural, religious, and finally humanitarian crises in the Arab world are man-made and can be attributed to both extrinsic and intrinsic factors. Central to the latter appears to be a shared cultural construct that can be termed “Arab reason.” This essay tries to present information on various aspects of the crisis; to understand why reform efforts come so late and why are they are more difficult for Arabs than for other Muslims. It continues by looking at the knowledge systems that govern Arab reason and their evolution, including the decisive role of the religious knowledge system. From there, it proposes some reform ideas including a renewed legal reasoning process with the goal of a future-oriented, knowledge-based, and inclusive Arab Islamic vision. A pragmatic way forward could be an additional unifying eighth legal school (madhhab/madhāhib) to counter sectarian conflicts and violence. This essay is built on a targeted literature search and is not a comprehensive review of the growing literature generated by distinguished thinkers on various aspects of Arab Islamic identity.
