AbstractAedes pulcritarsis is a tree-hole breeding species with its main distribution in the Mediterranean area. Within the scope of two independent monitoring programmes, this mosquito species was detected for the first time in Austria, in the province of Lower Austria (2018, districts Mistelbach and Gaenserndorf; 2020, district Bruck an der Leitha). As the climatic and habitat situation in Central Europe seems to be generally suitable for this species, the most likely explanation for the species not being recorded previously is that it might have been overlooked in the past due to its specialized breeding habitat. However, further research on the distribution of Ae. pulcritarsis in Austria would be needed to support this hypothesis. The results from this study will contribute to the investigation of the northern distribution limit of Ae. pulcritarsis in Europe and possible changes thereof.

Mosquito larval ecology is prerequisite for determining the larval abundance and species assemblage in mosquito control program. The study explored the association of five mosquito species with their breeding habitat diversity and species distribution in three selected parks from May to October, 2015. A total of 3217 mosquito larvae were reported from six breeding habitats, namely tree hole, leaf axils, water bottle, tire, drain and coconut shell. The frequency of the three species (Ae. aegypti, Ae. albopictus and Ar. subalbatus) coexistence was higher in tree holes (82.4%) than that of the other coexisting species. Pearson Chi-square result revealed that the association of species was significantly dependent on the breeding habitats. ANOVA further suggested that mosquito density varied across habitats where among the highest density of Cx. quinquefasciatus (3.87 ± 0.22) found in drain, followed by both Ae. albopictus (2.02 ± 0.17) and Ar. subalbatus (0.50 ± 0.09) in tree holes and Ae. aegypti (1.25 ± 0.23) in coconut shell. Cx. tritaeniorhynchus occurred in drain with the least observed density (0.03 ± 0.01). CCA results suggested that Aedes species were likely preferred to oviposit in shaded habitats where pH was associated with Ae. albopictus and dissolved oxygen was with Ae. aegypti and Ar. subalbatus. Culex species were positively associated with the habitats characterizing muddy bottom and emerging vegetation but not with any of the physico-chemical parameters. These findings concluded that ecological factors influence mosquito species to favor their breeding habitats can be helpful in controlling targeted vector species as well as the mosquito borne diseases.Bangladesh J.

We revisit the distribution and natural history data of Tachymenis chilensis chilensis (Schlegel, 1837) in Argentina based on compiled and novel records, extending its northern and southern distribution from the previously known localities in Argentina. We recorded two prey items in Argentinean populations: Rhinella rubropunctata, reported for the first time, and Liolaemus pictus. Tachymenis c. chilensis is mainly found in forested habitats, generally near wetlands with abundant populations of amphibians. The latitudinal range occupied by T. c. chilensis in Argentina is similar to that in Chile, but its northern distribution limit reaches the lowest latitudes in Chile. This is probably due to the higher humidity levels in the western slopes of the Andes and the barrier effect of the highest mountain ranges in this area.

Up to 1980, the important European airports and European airlines increased the number of their flights and passengers. As a result, it has been necessary to develop and launch airplanes with a high passenger capacity (e.g., Boeing 747, Jumbo, with 270 seats; Douglas DC 10 with 265 seats; and the Airbus A 300 with 249 seats). Simultaneously, the airports had to be enlarged or even rebuilt. After this substantial investment, the number of passengers began to decrease. In 1981, the French airline “Air France” expected a deficit of about 65 million DM (29.5 million US dollars), excluding the deficit by Concord. For the first time in 18 years, the Scandinavian airline “SAS” in 1980 had a deficit. The German airline “Lufthansa” expects no profits in 1981. This situation has been caused by rising oil prices, decreasing numbers of passengers, and a general recession. Many airlines have been reducing prices to attract more passengers. In spite of the high investments in new airplanes and modernizing airports, there has been little improvement in the necessary air- and ground-control-systems.In April 1981, the International Associates of Pilots (IFALPA) graded the security of air- and ground-control-systems of German airports as follows: deficient — Frankfurt and Bremen; seriously deficient — Hamburg, Stuttgart and Saarbrücken. According to the security scale of the IFALPA, the most important airports in the Mediterranean area were surveyed and estimated in 1977/78 as follows: deficient — Los Rodeos (Canary Islands), Las Palmas (Canary Islands), Lisbon, Faro, Malaga, Alicante, Madrid, Gerona, Ibiza, Palma de Mallorca, Venice and Roma; and critically deficient — Alghero, Rimini, Naples.

Food supply in the Mediterranean area has been recently modified by big retail distribution; for instance, industrial retail has favored shipments of groceries from regions that are intensive producers of mass food, generating a long supply chain (LSC) of food that opposes short supply chains (SSCs) that promote local food markets. However, the actual functional role of food retail and distribution in the determination of the risk of developing metabolic syndrome (MetS) has not been studied hitherto. The main aim of this study was to test the effects of food chain length on the prevalence of MetS in a population accustomed to the Mediterranean diet. We conducted an observational study in Southern Italy on individuals adhering to the Mediterranean diet. We examined a total of 407 subjects (41% females) with an average age of 56 ± 14.5 years (as standard deviation) and found that being on the Mediterranean diet with a SSC significantly reduces the prevalence of MetS compared with the LSC (SSC: 19.65%, LSC: 31.46%; p: 0.007). Our data indicate for the first time that the length of food supply chain plays a key role in determining the risk of MetS in a population adhering to the Mediterranean diet.

Trieste is located at the extreme end of the northern coast of the Adriatic, where the arm of the sea reaches most deeply into the European continent. By its position Trieste is thus a part of Central Europe no less than of the Mediterranean area — if we take into account the fact that the distance between Vienna and Trieste is less than that between Trieste and Rome. On the other hand, Trieste is in an area where the Apennine peninsula meets the Balkan, where for millenia two cultural spheres have been juxtaposed: the Eastern — Greek, Byzantine and Slavic — and the Western — Latin, Romance and German. The complexity of the geographical and cultural circumstances is further increased by the national heterogeneousness of the inhabitants, Italians and Slovenes. Italians predominate in the town, Slovenes in the countryside.

Imperator contra praedones Some Remarks on the Illegality of the lex GabiniaSummaryIn 67 BC Aulus Gabinius, a tribunus plebis, proposed a law appointing an imperator to deal with the pirates of the Mediterranean area. The law was passed as lex Gabinia de uno imperatore contra praedones constituendo and the senate was asked to choose the right candidate. The only possible choice was Gnaeus Pompeius Magnus, the most talented and famous general of the time. The senators opposed so violently that Gabinius was almost killed. Thus, another assembly was called which appointed Pompey to the task. His campaign against the pirates was amazingly fast and successful.There are several reasons for treating this case as a deviation from the republican constitution. Firstly, the imperium was given for a period of three years which was unusually long time for an extraordinary command. Secondly, the general was given power on the whole Mediterranean area, equal to this of the provincial governors. Thirdly, he could choose his own legati which was a case unknown to the republican system. Moreover, it was the first time when an extraordinary command was given by the concilia plebis regardless the senatorial opposition.The case of lex Gabinia was one of Pompey’s numerous victories over the republic. Notwithstanding, he managed to persuade everyone to picture himself as a hero and defender o f the republic.

Abstract. A simulation of the last millennium is compared to a recent spatio-temporal reconstruction of summer temperature over Europe. The focus is on the response to solar forcing over the pre-industrial era. Although the correlation between solar forcing and the reconstruction remains small, the spatial regression over solar forcing shows statistically significant regions. The meridional pattern of this regression is found to be similar in the model and in the reconstruction. This pattern exhibits a large warming over Northern and Mediterranean Europe and a lesser amplitude response over Central Europe. The mechanisms explaining this pattern in the simulation are mainly related to evapotranspiration fluxes. It is shown that the evapotranspiration is larger in summer over Central Europe when solar forcing increases, while it decreases over the Mediterranean area. The explanation for the evapotranspiration increase over Central Europe is found in the increase of winter precipitation there, leading to a soil moisture increase in spring. As a consequence, the evapotranspiration is larger in summer, which leads to an increase in cloud cover over this region, reducing the surface shortwave flux there and leading to less warming. Over the Mediterranean area, the surface shortwave flux increases with solar forcing, the soil becomes dryer and the evapotranspiration is reduced in summer leading to a larger increase in temperature. This effect appears to be overestimated in the model as compared to the reconstruction. Finally, the warming of Northern Europe is related to the albedo feedback due to sea-ice cover retreat with increasing solar forcing. These results show that the last millennium can be useful to evaluate the sensitivity of climate models to radiative forcing changes, using spatio-temporal reconstruction of climate.

Poa maroccana is an annual Mediterranean species, which is recorded for the first time from Sicily and for the whole Italian territory. It usually occurs in synanthopic habitats, represented mainly by urban and suburban roadsides, where it is quite sporadic. Based on current knowledge, it has been hitherto reported only in a few localities of the Mediterranean area, particularly in Morocco, Algeria, Tunisia, Libya, Spain, Portugal, Greece, Turkey, Syria and Crimea. Field observations and herbarium investigations have shown that this species is often mistaken for P. annua, mainly due to its morphological similarities, as well as for the same ecological needs, therefore its real geographical distribution has yet to be verified. Although the two species are both tetraploids (2n = 28), they clearly differ for numerous relevant features concerning the shape and size of ligules, inflorescence, spikelet, glumes, palea, lemma, anthers, lodicules and seed. In order to better clarify the relationships of P. maroccana with P. annua and the other annual species of this genus occurring in the Mediterranean, its carefull a morphological description and iconography is provided, as well as a comparative morphological table of all allied species and also their analytical key for easy identification.
