A short communication to define the overcurrent protection system of the CIGRE European benchmark distribution networks for RES penetration studies

The use of clean energies in distribution networks is an unstoppable trend which has a significant positive impact on the progressive power system decarbonization. However, it has to be considered that conventional distribution systems have been designed to operate as passive networks. Therefore, a massive penetration of distributed generation may create several operational problems, such as malfunction of the protection systems, which may limit the deployment of this technology. The analysis of these limitations by means of representative benchmark networks is of utmost importance. Most of the proposed benchmark networks proposed so far, however, lack of information about their protection system. To overcome this shortcoming, this letter specifies the protection system of the benchmark European distribution networks proposed by the CIGRE Task Force C06.04.02 for this purpose. In this way, this letter facilitates the analysis of the possible impact that renewable energy sources may have in the distribution system protections.

Stenopterygiids from the lower Toarcian of Beaujolais and a chemostratigraphic context for ichthyosaur preservation during the Toarcian Oceanic Anoxic Event

We report new ichthyosaur material excavated in lower Toarcian levels of the LafargeHolcim Val d'Azergues quarry in Beaujolais, SE France. A partially articulated skull and a smaller, unprepared but likely subcomplete skeleton preserved in a carbonate concretion are identified as stenopterygiids, a family of wide European distribution during the Early Jurassic. These specimens are among the finest preserved Toarcian exemplars known from Europe and in one of them, soft tissue preservation is suspected. Their state of preservation is attributed to the combination of prolonged anoxic conditions near the water-sediment interface and early carbonate cementation resulting from the activity of sulfate-reducing bacteria. We also present carbon and strontium isotope values obtained from the study site that allow detailed temporal comparisons with other Toarcian vertebrate-yielding sites and environmental perturbations associated with the Toarcian Oceanic Anoxic Event (T-OAE). These comparisons suggest that the relatively high abundance and good preservation state of Toarcian vertebrates was favoured by a prolonged period of low bottom water oxygenation and accumulation rates. The environmental conditions that prevailed during the T-OAE were probably responsible for the extensive nature of Lagerstätte-type deposits with exceptional preservation of marine organisms. Whether the T-OAE had a biological impact on marine vertebrates requires a precise chemostratigraphic context of the fossil record spanning the Pliensbachian-Toarcian interval.Supplementary material at https://doi.org/10.6084/m9.figshare.c.5315223

Impact of European pet antibiotic use on enterococci and staphylococci antimicrobial resistance and human health

Due to the inappropriate use of antibiotics described in both human and veterinary medicine, there is emerging evidence of antimicrobial-resistant organisms isolated from humans and pets, forming a multifaceted problem. Although the true magnitude of antimicrobial resistance in pets and other animals, as well as humans, are not fully known; pets, in particular dogs and cats, can contribute to the spread of antimicrobial resistance due to close contact with humans and their status as a family member in urban households. This review summarizes and highlights the current data concerning the antibiotic use on pets, and the European distribution of the increasing prevalence of multiresistant bacterial pathogens, such as enterococci and methicillin-resistant staphylococci on pets, as well as its implications for public health.

A new species of the genus Archiboreoiulus Brolemann, 1921 (Diplopoda, Julida) from Movile Cave (Southern Dobrogea, Romania)

Up to the present, the genus Archiboreoiulus included only two species: A. sollaudi from France and A. pallidus with a wide European distribution range. Here we describe a previously unknown species of the genus Archiboreoiulus, A. serbansarbui, collected from the mesothermal sulfurous Movile Cave, Mangalia, Romania, harboring a rich and diverse troglobitic community.

Expanding the European distribution limits of Bruchidius raddianae. First record in Portugal from Vachellia karroo’s infested seeds (Coleoptera: Bruchidae; Fabales: Fabaceae)

Several Australian and African Acacia shrubs and trees have been intentionally introduced into the Mediterranean basin for different purposes, but some species become invasive, such as Vachellia karroo (Hayne) Banfi and Galasso (syn. Acacia karroo) (Fabales: Fabaceae). The seed beetles, belonging to family Bruchidae, have a significant ecological and economic importance, either because they can be plant pests or, on the other hand, be used as biocontrol agents against invasive plant species. Bruchidius raddianae (Anton and Delobel, 2003) (Coleoptera: Bruchidae) is native to tropical and subtropical areas, but it has been recently reported from Cádiz and Málaga (southern Spain, 2007) and in the Lampedusa Island (Italy, 2015) from seeds of pods collected from V. karroo. This paper reports 104 specimens reared from seeds collected from V. karroo in Faro (southern Portugal) from August to October 2019, expanding the B. raddianae’ European distribution limits. This is also the first report of its presence in Portugal and the third in Europe.

On the identity of Paracacoxenus kaszabi Okada, with the formal description of a new closely related species (Diptera, Drosophilidae)

In order to clarify the identity of Paracacoxenus kaszabi Okada, 1973, a species described from Mongolia, the morphological structures of one male paratype, collected at 1,750 m altitude, were analyzed and redescribed. In addition, one of the male specimens, previously referred to in literature as ‘sp. aff. kaszabi’, is restudied and described as Paracacoxenus macaisp. nov. (type locality: Schmelz, Parco Nazionale dello Stelvio, Province of Bolzano, Region of Trentino-Alto Adige, Italy). The former species seems to be distributed in central and eastern Asia while the latter is supposed to have an exclusively European distribution. The midtibial preapical seta of male Paracacoxenus argyreator (Frey, 1932), which is unusually long, is illustrated by photomicrographs. A key to the European species of Paracacoxenus Hardy, 1960 is presented.
