Abstract Ecological niche models have proved to be a powerful tool in assessing invasiveness risk of alien species, allowing the optimization of control strategies. Vespa velutina (Hymenoptera: Vespidae) is an invasive species with strong ecological, economical and health impacts in Europe after it first report in France in 2004. It was detected for the first time in a Mediterranean island (Mallorca, Balearic Islands, Spain) in 2015, where a single nest was found in the northwest of the island. Immediately a control plan was implemented. In this study, we analysed 30 occurrence data in Mallorca island to assess the suitability distribution predicted to Mediterranean island conditions using ensemble of small models. We obtained high values of AUC (0.9165), Somers’ D (0.8331), Boyce (0.7611) and TSS (0.7754) as quality parameters of the final ensembled model. We show for the first time that there are suitable areas where this species can expand and stablish, mainly in steeper slopes and low isothermality zones. Likewise, the distribution suitability of V. velutina for other Mediterranean islands (Ibiza, Formentera, Menorca, Corsica, Sardinia, Sicily, Crete and Cyprus) was also explored, showing potentially suitable zones. This study provides valuable information regarding the areas in the Mediterranean islands under risk of invasion, and it could be used by both scientists and managers for an early detection and control of the invasive species due to its cost-effectiveness in terms of conservation.

With a geological history of long isolation, fragmentation, partial submersion, and subsequent rising, characterized by a remarkable diversity in topology, geology, and habitats, and the fifth-largest island of the Mediterranean, Crete has provided an ideal setting for speciation and developing a unique and diverse Staphylinidae fauna. Although beginning already in the middle of the 19th century, the exploration of this fauna gained momentum only recently. Based on a critical revision of literature data, on material collected during several recent field trips, and on additional previously unpublished records, a checklist of the Staphylinidae of Crete is compiled, including as many as 397 named species, with 115 of them reported from the island for the first time and with 48 new species described in the second part of the monograph. Additional unidentified and unnamed species, as well as species doubtfully or erroneously recorded from Crete are listed separately. The systematic, zoogeographic, and ecological composition of the Staphylinidae fauna is characterized with a special focus on the endemics. The latter are represented by 111 named and at least ten unnamed species, account for nearly one-third of the fauna, and mainly belong to the subfamilies Aleocharinae, Scydmaeninae, Pselaphinae, Paederinae, Leptotyphlinae, Staphylininae, and Omaliinae. More than half of them are even locally endemic. The genera with the greatest number of endemic species are Cephennium Müller & Kunze, 1822 of the Scydmaeninae (twelve named species) and Geostiba Thomson, 1858 of the Aleocharinae (nine named species). More than two-thirds of the endemic species are epigeic inhabitants of forests, bush and shrub habitats, grassland, and wetlands, approximately one-fourth is confined to deeper soil strata or endogean, and 8 % are myrmephilous. Slightly more than half (59 species; 53 %) of the endemics are most likely the result of in-situ radiation (18 lineages), the remainder of vicariance with mainland species. A comparison with other Mediterranean islands revealed that (a) total diversity of the Cretan fauna is significantly greater than that of other East Mediterranean islands except Corfu, but much lower than that of Corsica, Sardinia, and Sicily, (b) regarding the number of endemic species Crete ranks third behind Corsica and Sardinia, and (c) the rate of endemism is greater in Crete than in any other Mediterranean island. Explanations for the observed differences in the diversity and composition of the faunas of the islands are discussed. Stichoglossa graeca Bernhauer, 1905, a species of which previously only the lectotype was known, is redescribed and illustrated. Six synonymies are proposed and one name is revalidated: Phloeocharis longipennis Fauvel, 1875 = P. hummleri Bernhauer, 1915, syn. nov.; Phytosus balticus Kraatz, 1859 = P. holtzi Bernhauer, 1935, syn. nov.; Atheta nigra (Kraatz, 1856) = A. biroi Scheerpeltz, 1964, syn. nov.; Domene stilicina (Erichson, 1840) = D. lohseiana Bordoni, 1977, syn. nov.; Oedichirus rubronotatus Pic, 1903, revalidated = O. reitteri Bernhauer, 1908, syn. nov.; Pseudolathra quadricollis (Fauvel, 1875) = P. cretensis Bordoni, 1986, syn. nov. A lectotype is designated for Stichoglossa graeca Bernhauer, 1905. Two species are reported from Greece for the first time.

Originally from Asia, Hierodula patellifera (Serville, 1839) occurs several Mediterranean countries, such as Italy. These arrivals could come from many factors: new pets or commercial human transport. The presence of Hierodula patellifera (Serville, 1839) is here reported for the first time in France. A well settled and probably widespread population of this species is here discussed as its adaptability to the Mediterranean climate. Some considerations on the potential impacts on the local ecosystems and its future spreading in Europe as an invasive species are given.

AbstractThe Mediterranean basin is a hotspot of biodiversity, fuelled by climatic oscillation and geological change over the past 20 million years. Wall lizards of the genus Podarcis are among the most abundant, diverse, and conspicuous Mediterranean fauna. Here, we unravel the remarkably entangled evolutionary history of wall lizards by sequencing genomes of 34 major lineages covering 26 species. We demonstrate an early (>11 MYA) separation into two clades centred on the Iberian and Balkan Peninsulas, and two clades of Mediterranean island endemics. Diversification within these clades was pronounced between 6.5–4.0 MYA, a period spanning the Messinian Salinity Crisis, during which the Mediterranean Sea nearly dried up before rapidly refilling. However, genetic exchange between lineages has been a pervasive feature throughout the entire history of wall lizards. This has resulted in a highly reticulated pattern of evolution across the group, characterised by mosaic genomes with major contributions from two or more parental taxa. These hybrid lineages gave rise to several of the extant species that are endemic to Mediterranean islands. The mosaic genomes of island endemics may have promoted their extraordinary adaptability and striking diversity in body size, shape and colouration, which have puzzled biologists for centuries.

Echinococcus Granulosus Sensu Lato

Cystic echinococcosis (CE) is a zoonosis that is prevalent worldwide. It is considered endemic in Portugal but few studies have been performed on Echinococcus granulosus sensu lato and their hosts. In this study, CE cysts are reported for the first time in a free-living wild boar (Sus scrofa) in Portugal. The presence of the metacestodes in the liver of the wild boar was identified by morphological features, microscopic examination and molecular analysis. The sequencing of part of the DNA nuclear ribosomal internal transcribed spacer-1 (ITS-1) region revealed a G5 genotype that presently corresponds to Echinococcus ortleppi. This is the first report of E. ortleppi in Portugal and to the best of the authors’ knowledge, in Europe. These results suggest that wild boar may be a host of CE, namely, crossing the livestock–wildlife interface, which has important public health implications. Wildlife reservoirs must be taken into account as CE hosts and surveillance of game as well as health education for hunters should be implemented using a One Health approach, with implementation of feasible and tailor-made control strategies, namely, proper elimination of byproducts in the field.

Pm2.5 Concentration

The Community Multiscale Air Quality (CMAQ) measurement was employed for evaluating the effectiveness of fine particulate matter control strategies in Taiwan. There are three scenarios as follows: (I) the 2014 baseline year emission, (II) 2020 emissions reduced via the Clean Air Act (CAA), and (III) other emissions reduced stringently via the Clean Air Act. Based on the Taiwan Emission Data System (TEDs) 8.1, established in 2014, the emission of particulate matter 2.5 (PM2.5) was 73.5 thousand tons y−1, that of SOx was 121.3 thousand tons y−1, and that of NOx was 404.4 thousand tons y−1 in Taiwan. The CMAQ model simulation indicated that the PM2.5 concentration was 21.9 μg m−3. This could be underestimated by 24% in comparison with data from the ambient air quality monitoring stations of the Taiwan Environmental Protection Administration (TEPA). The results of the simulation of the PM2.5 concentration showed high PM2.5 concentrations in central and southwestern Taiwan, especially in Taichung and Kaohsiung. Compared to scenario I, the average annual concentrations of PM2.5 for scenario II and scenario III showed reductions of 20.1% and 28.8%, respectively. From the results derived from the simulation, it can be seen that control of NOx emissions may improve daily airborne PM2.5 concentrations in Taiwan significantly and control of directly emitted PM2.5 emissions may improve airborne PM2.5 concentrations each month. Nevertheless, the results reveal that the preliminary control plan could not achievethe air quality standard. Therefore, the efficacy and effectiveness of the control measures must be considered to better reduce emissions in the future.

Abstract Isodontia mexicana (Hymenoptera, Sphecidae), a New Invasive Wasp Species in the Fauna of Ukraine Reared from Trap-Nests in the Crimea. Fateryga, A. V., Protsenko, Yu. V., Zhidkov, V. Yu. - Th e North American wasp Isodontia mexicana was found for the first time in Ukraine in trap-nests operated near Pushkino (southern coast of the Crimea) in 2012. Th ree nests contained five cocoons, from which only one adult wasp emerged in 2013, allowing the positive identification; other cocoons were either empty (one) or destroyed by Melittobia acasta (three). Such a find of a newly established invasive species in Ukraine represents the easternmost point in its European range and possibly the most remarkable jump-dispersal event in its distribution.

Purpose The share of renewable energy sources (RESs) in the power system is increasing day by day. The RESs are intermittent, therefore maintaining the grid stability and power balance is very difficult. The purpose of this paper is to control the inverters in microgrid using different control strategies to maintain the system stability and power balance. Design/methodology/approach In this paper, different control strategies are implemented to the voltage source converter (VSC) to get the desired performance. The DQ control is a basic control strategy that is inherently present in the droop and virtual synchronous machine (VSM) control strategies. The droop and VSM control strategies are inspired by the conventional synchronous machine (SM). The main objective of this work is to design and implement the three aforementioned control strategies in microgrid. Findings The significant contributions of this work are: the detailed implementation of DQ control, droop control and VSM control strategies for VSC in both grid-connected mode and standalone mode is presented; the MATLAB/Simulink simulation results and comparative studies of the three aforementioned controllers are introduced first time in the proposed work; and the opal-RT digital real-time simulation results of the proposed VSM control show the superiority in transient response compared to the droop control strategy. Research limitations/implications In the power system, the power electronic-based power allowed by VSM is dominated by the conventional power which is generated from the traditional SM, and then the issues related to stability still need advance study. There are some differences between the SM and VSM characteristics, so the integration of VSM with the existing system still needs further study. Economical operation of VSM with hybrid storage is also one of the future scopes of this work. Originality/value The significant contributions of this work are: the detailed implementation of DQ control, droop control and VSM control strategies for VSC in both grid-connected mode and standalone mode is presented; the MATLAB/Simulink simulation results and comparative studies of the three aforementioned controllers are introduced first time in the proposed work; and the opal-RT digital real-time simulation results of the proposed VSM control show the superiority in transient response compared to the droop control strategy.
