A captorhinid-dominated assemblage from the palaeoequatorial Permian of Menorca (Balearic Islands, western Mediterranean)

Altres ajuts: CERCA Programme/Generalitat de CatalunyaMoradisaurine captorhinid eureptiles were a successful group of high-fibre herbivores that lived in the arid low latitudes of Pangaea during the Permian. Here we describe a palaeoassemblage from the Permian of Menorca (Balearic Islands, western Mediterranean), consisting of ichnites of small captorhinomorph eureptiles, probably moradisaurines (Hyloidichnus), and parareptiles (cf. Erpetopus), and bones of two different taxa of moradisaurines. The smallest of the two is not diagnostic beyond Moradisaurinae incertae sedis. The largest one, on the other hand, shows characters that are not present in any other known species of moradisaurine (densely ornamented maxillar teeth), and it is therefore described as Balearosaurus bombardensis gen. et sp. nov. Other remains found in the same outcrop are identified as cf. Balearosaurus bombardensis gen. et sp. nov., as they could also belong to the newly described taxon. This species is sister to the moradisaurine from the lower Permian of the neighbouring island of Mallorca, and is also closely related to the North American genus Rothianiscus. This makes it possible to suggest the hypothesis that the Variscan mountains, which separated North America from southern Europe during the Permian, were not a very important palaeobiogeographical barrier to the dispersion of moradisaurines. In fact, mapping all moradisaurine occurrences known so far, it is shown that their distribution area encompassed both sides of the Variscan mountains, essentially being restricted to the arid belt of palaeoequatorial Pangaea, where they probably outcompeted other herbivorous clades until they died out in the late Permian

La nécropole néolithique de la Feixa del Moro (Juberri, Andorre): Examen et nouvelles données

At the beginning of the 1980s, a series of archaeological interventions carried out by what was previously called the 'Servei d'Investigacions Arqueológiques del Patrimoni Artistic Nacional d'Andorra' in a Pyrenean valley in Andorra allowed the investigation of the Feixa del Moro site. In a high-altitude area below a series of abandoned terraces, several dwellings and burial structures were located, all of them with chronologies ranging between the Early and the Middle Neolithic (from the mid 5th millennium to the early 4th millennium cal. BC). The distinctiveness of this site does not only lie in its geographical location, nor in the kind of structures discovered, but also in the very good state of preservation of the human bone material recovered from the burials, making Feixa del Moro one of the reference sites for the Neolithic in the Pyrenees and, in general, the Western Mediterranean. So far, sites with a similar conservation of both bones and burial structures are really uncommon. Moreover, the concentration in so small an area, and in the same stratigraphic unit, of such a diversity of evidence, including burials, silos and hearths, is yet more unusual. There are no similar sites in Andorra, or even in the entire Pyrenees. The only other burial site of comparable chronology discovered in the area is the Segudet site, and only a few high-altitude Neolithic dwelling sites are known. Even if cist burials are quite common in the northeast of the Iberian Peninsula and in Southern France, Feixa del Moro is the first that has been found at high altitude. The archaeological work undertaken between 1983 and 1985 provided a picture of a farming community belonging to the so-called 'Sepulcros de fosa' Culture, established in the very heart of the Pyrenees and, thus, highlighted the complexity of Neolithic settlement patterns, even in mountainous zones. At the same time, several analyses of the archaeological materials were already carried out, making Feixa del Moro a reference site for archaeological research even now. Nevertheless, three decades later, new methodologies and the technical advances available are allowing archaeologists to refine old interpretations, to reopen old debates and to carry out new analyses that can improve our understanding of the past. In this respect, since 2011, within the research project 'Aproximación a las primeras comunidades neolíticas del NE peninsular a través de sus prácticas funerarias' (HAR2011-23149), funded by the Spanish Ministry for the Economy and Competitiveness, a group of interdisciplinary researchers have begun to study several Neolithic burial contexts in the northeast of the Iberian Peninsula, among which Feixa del Moro. Following this perspective, in this paper, we present the outcome of the new analyses carried out on the burial goods and of the biochemistry and radiocarbon analyses carried out on the human bone material from the three cist burials of Feixa del Moro, with the aim of better understanding the early farming communities who settled in the Pyrenees. Since the last archaeological work carried out in the 1990s, large quantities of data have been lost. This has produced a certain degree of confusion and misunderstanding that has been repeated in other studies undertaken a posteriori on the site by other scholars. Some of these interpretations need to be revised. That it is why, within the current research project, we are not only bringing in new analyses, but also re-examining all the old written and graphic information available, as well as the state of the conserved archaeological material. The data presented in this paper resume all the available information on the Feixa del Moro site, correcting old mistakes and bias, updating the 1980s archaeological registers and presenting new analyses as well. Our aim is to ensure that Feixa del Moro remains a reference site for the Pyrenean and Western Mediterranean Neolithic. At the same time, we wish to encourage other researchers to undertake new analyses and to embrace new perspectives in order to improve our understanding of Neolithic societies

Views on a brief mindfulness intervention among patients with long-term illness.

BACKGROUND: Chronic illness is the leading cause of death in the UK and worldwide. Psychological therapies to support self-management have been shown to play an important role in helping those with chronic illness cope; more recently, the therapeutic benefits of mindfulness approaches have become evident for managing depression and other distressing emotions. Brief guided mindfulness interventions, are more convenient than intensive traditional programmes requiring regular attendance but have been less explored. This study assessed views on a brief (i.e., 10 min) mindfulness intervention for those with specific long-term illnesses. METHODS: Semi-structured interviews and focus groups were conducted with chronic illness patient groups (i.e., chronic obstructive pulmonary disease, chronic pain and cardiovascular disease), designed to capture the acceptability and feasibility of the intervention. The interviews were conducted after use of a mindfulness based audio in clinic and, one week later, after use in the patient's own environment. Interviews were recorded, transcribed and analysed using thematic analysis. RESULTS: In total, a combination of 18 interviews and focus groups were conducted among 14 patients. Recruitment was most successful with chronic pain patients. All patients reported benefits such as feelings of relaxation and improved coping with symptoms. While the wording and content of the audio were generally well received, it was suggested that the length could be increased, as it felt rushed, and that more guidance about the purpose of mindfulness, and when to use it, was needed. CONCLUSIONS: A brief mindfulness intervention was well accepted among patients with long-term illness. The intervention may benefit by being lengthened and by offering further guidance on its use

Using jasmonates and salicylates to reduce losses within the fruit supply chain

The fresh produce industry is constantly growing, due to increasing consumer demand. The shelf-life of some fruit, however, is relatively short, limited by microbial contamination or visual, textural and nutritional quality loss. Thus, techniques for reducing undesired microbial contamination, spoilage and decay, as well as maintaining product’s visual, textural and nutritional quality are in high demand at all steps within the supply chain. The postharvest use of signalling molecules, i.e. jasmonates and salicylates seems to have unexplored potential. The focus of this review is on the effects of treatment with jasmonates and salicylates on the fresh produce quality, defined by decay incidence and severity, chilling injury, maintenance of texture, visual quality, taste and aroma, and nutritional content. Postharvest treatments with jasmonates and salicylates have the ability to reduce decay by increasing fruit resistance to diseases and reducing chilling injury in numerous products. These treatments also possess the ability to improve other quality characteristics, i.e. appearance, texture maintenance and nutritional content. Furthermore, they can easily be combined with other treatments, e.g. heat treatment, ultrasound treatment. A good understanding of all the benefits and limitations related to the postharvest use of jasmonates and salicylates is needed, and relevant information has been reviewed in this paper

A New Crocodylian from the Late Maastrichtian of Spain: Implications for the Initial Radiation of Crocodyloids

The earliest crocodylians are known primarily from the Late Cretaceous of North America and Europe. The representatives of Gavialoidea and Alligatoroidea are known in the Late Cretaceous of both continents, yet the biogeographic origins of Crocodyloidea are poorly understood. Up to now, only one representative of this clade has been known from the Late Cretaceous, the basal crocodyloid Prodiplocynodon from the Maastrichtian of North America.The fossil studied is a skull collected from sandstones in the lower part of the Tremp Formation, in Chron C30n, dated at -67.6 to 65.5 Ma (late Maastrichtian), in Arén (Huesca, Spain). It is located in a continuous section that contains the K/P boundary, in which the dinosaur faunas closest to the K/P boundary in Europe have been described, including Arenysaurus ardevoli and Blasisaurus canudoi. Phylogenetic analysis places the new taxon, Arenysuchus gascabadiolorum, at the base of Crocodyloidea.The new taxon is the oldest crocodyloid representative in Eurasia. Crocodyloidea had previously only been known from the Palaeogene onwards in this part of Laurasia. Phylogenetically, Arenysuchus gascabadiolorum is situated at the base of the first radiation of crocodyloids that occurred in the late Maastrichtian, shedding light on this part of the cladogram. The presence of basal crocodyloids at the end of the Cretaceous both in North America and Europe provides new evidence of the faunal exchange via the Thulean Land Bridge during the Maastrichtian

New insights into the neolithisation process in southwest Europe according to spatial density analysis from calibrated radiocarbon dates

The agricultural way of life spreads throughout Europe via two main routes: the Danube corridor and the Mediterranean basin. Current archaeological literature describes the arrival to the Western Mediterranean as a rapid process which involves both demic and cultural models, and in this regard, the dispersal movement has been investigated using mathematical models, where the key factors are time and space. In this work, we have created a compilation of all available radiocarbon dates for the whole of Iberia, in order to draw a chronological series of maps to illustrate temporal and spatial patterns in the neolithisation process. The maps were prepared by calculating the calibrated 14C date probability density curves, as a proxy to show the spatial dynamics of the last hunter-gatherers and first farmers. Several scholars have pointed out problems linked with the variability of samples, such as the overrepresentation of some sites, the degree of regional research, the nature of the dated samples and above all the archaeological context, but we are confident that the selected dates, after applying some filters and statistical protocols, constitute a good way to approach settlement spatial patterns in Iberia at the time of the neolithisation process

Geographical and temporal distribution of SARS-CoV-2 clades in the WHO European Region, January to June 2020

We show the distribution of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) genetic clades over time and between countries and outline potential genomic surveillance objectives. We applied three genomic nomenclature systems to all sequence data from the World Health Organization European Region available until 10 July 2020. We highlight the importance of real-time sequencing and data dissemination in a pandemic situation, compare the nomenclatures and lay a foundation for future European genomic surveillance of SARS-CoV-2
