Abstract A new genus and species, Austrocupressinoxylon barcinense , based on remains of cupressaceous wood is described for the Lower Cretaceous of central Patagonia, Argentina. The studied specimens are silicified fragments of picnoxylic and homoxylic wood that exhibit a combination of characters not previously reported, therefore a new genus is erected. The characters are: 1- growth ring boundaries distinct, 2- transition from earlywood to latewood gradual, 3- axial parenchyma diffuse,4- radial tracheid pitting predominantly abietinean,5- cross-field pitting cupressoid, arranged in both cupressoid and araucarioid patterns, 6- rays uniseriate heterocellular, 7- end and horizontal walls of ray parenchyma cells smooth or slightly nodular, and 8- ray tracheids with smooth walls. The cross-field pitting patterns and the presence of ray tracheids are two traits of particular interest in the context of systematic affinities. The fragments were collected from two stumps found in life position attached to each other by a main root, consequently, the disposition of the stumps suggests a case of clonal growth by root suckering. This is the second report of such mechanisms in the fossil records worldwide and the first one for South America. [ABSTRACT FROM AUTHOR]

Diclofenac has recently been included in the first watch list of substances to be monitored in all member states so as to evaluate its future inclusion in the priority substances list by the Water Framework Directive. Therefore, in view of upcoming limitations on diclofenac discharge, the objective of this work was to assess its removal from water by a microalgae-based treatment. Moreover, considering microalgae application in wastewater treatment, it was aimed to verify if their nutrient removal capacity was affected by the presence of diclofenac. For a comparison purpose, three different microalgae strains, namely Chlorella sorokiniana , Chlorella vulgaris and Scenedesmus obliquus , were cultured in photobioreactors under identical controlled conditions. For the three strains, the addition of diclofenac meant an organic carbon source and provided higher biomass concentration. C. sorokiniana was the strain showing the largest increase of growth rate and microalgae density, which were above 25% and 31%, respectively, compared with the positive control. However, S. obliquus showed the highest efficiency in the removal of diclofenac (> 79%) and nutrients (> 87% nitrates, > 99% phosphates) per litre and per gram of biomass. These results pointed to the potential application of microalgae for the removal of pharmaceuticals in the bioremediation of wastewater. [ABSTRACT FROM AUTHOR]

Despite the importance of the socio-economic dimension of the use of marine waters, there has been little research in the field until recently, when interest has grown in the concept of ‘blue growth'. This paper aims to contribute to filling this gap with a socio-economic assessment of the main maritime sectors, focused on the Spanish part of the European Atlantic Arc. To this end, it first proposes a theoretical structure for the maritime economy and then collects and classifies comparable and reliable maritime socio-economic indicators. The data obtained allows us to assess the size of the Spanish maritime sector and the position of the Spanish Maritime Cluster in the wider context of the maritime economy of the European Atlantic, as well as discuss the appropriateness of a strategy of forming clusters at the national level vs. a transnational approach. The results indicate differences between regions in the European Atlantic Arc that complicate the development of integrated policies to stimulate blue growth. Extending our knowledge of the maritime economy of the European Atlantic Arc will make it possible to design strategies that address the real issues, increasing the likelihood of these being effective.

This study explores the effects of gentrification processes on non-displaced seniors. To this end, we conducted a qualitative study, using a cross-sectional phenomenological design. Through 29 semi-structured interviews we analysed the narratives of elderly people with regard to the changes experienced in the Barceloneta neighbourhood of the city of Barcelona, Spain, during the last decades. We interpreted the results from the perspective of grief using as a reference the dual process model of coping with bereavement. Those interviewed reported experiencing losses related to the commercial fabric, community spaces, perceptions of safety and the family or neighbourhood fabric. These losses generate negative effects on health and also weaken the sources of social support that could once have protected against the effects of them. Most of the narratives collected include observations similar to those that occur in bereavement processes that are focused on loss. The results provide further arguments on the need to design urban policies from the perspective of community health, and suggest professional actions aimed at preventing risks to health and social cohesion caused by gentrification processes. • Gentrification processes in large cities have an impact on elderly people's health. • Non-displaced elderly people suffer the negative consequences of gentrification. • Changes in the neighbourhood and the loss of the social support are main elements. • Losses sustained by non-displaced elderly people may take the form of bereavement. • There is a need for urban policies from the perspective of community health.

Today, the ginkgophytes are represented by the single species Ginkgo biloba , naturally distributed in China and cultivated worldwide. However, the ginkgophyte lineage shows an extensive fossil record going back to the Paleozoic of both hemispheres. In South America, its record began in the upper Paleozoic and reached the middle Eocene, and it includes both vegetative and reproductive remains. The Cretaceous macrofossil record of this group in South America is restricted to Lower Cretaceous deposits, where it is relatively abundant, whereas there is a gap in its Upper Cretaceous to lower Paleogene record. We present the new species Ginkgoites villardeseoanii collected from Maastrichtian (uppermost Cretaceous) deposits of the Lefipán Formation (Patagonia, Argentina). The studied material consists of three specimens preserved as adpressions of isolated, flabellate, and petiolate (Ginkgo -like) leaves, with few epidermal characters preserved. One of the studied specimens shows evidence of insect damage consistent with hole feeding, constituting the first Cretaceous record of interaction between ginkgophytes and insects in the Southern Hemisphere. We infer that this damage was produced when the leaf was still attached to the plant, as the specimen shows evidence of a physiological reaction of the plant in the form of a border of necrotic tissue around the wound. Ginkgoites leaves are common among different lineages within the Ginkgoales, having been associated to three families (Ginkgoaceae, Karkeniaceae, and Yimaiaceae). Therefore, G. villardeseoanii was assigned to an incertae sedis family. [Display omitted] • We describe leaf remains and erect the new species Ginkgoites villardeseoanii. • G. villardeseoanii would belong either to Karkeniaceae or Ginkgoaceae. • We describe the first ginkgophyte-insect interaction Cretaceous record worldwide. • The fossil record of insect damage on Ginkgophyta is scarce. • Insect-repellent properties could be a cause of the lineage success and longevity.

Abstract: The fluvial, lacustrine and tuffaceous sedimentary succession of the Cañadón Asfalto continental basin exposed in the Argentinean Chubut Province of central Patagonia preserves an extraordinary record of Jurassic fauna and flora that marks key events in the evolution of Dinosauria, early mammals and major South American plant groups. However, basin-wide correlation of the fossiliferous units is complicated by fault displacements, unconformities and repetitive lithofacies. New U–Pb analyses of zircon (CA-TIMS method) from five primary tuff beds interstratified with the lacustrine strata establish a new chronostratigraphic framework for the sedimentary and volcanic units of Cañadón Asfalto Basin, constraining ca. 33m.y. of depositional history and biotic evolution that spans nearly all three epochs of the Jurassic. Five major vertebrate- and plant-rich stratigraphic intervals have been identified, and are being actively investigated, that range in age from Pliensbachian to Kimmeridgian (or younger). Our combined biostratigraphic and high-precision geochronologic results indicate that the major faunal turnover of the sauropodomorph dinosaurs which led to the rise of the eusauropods took place in the Early Jurassic, earlier than previously recognized. Similarly, the first successful radiation of the ornithischian dinosaurs (heterodontosaurids), as well as the evolutionary diversifications of the araucarian conifers and the osmundaceous ferns, all occurred before the end of the Early Jurassic. The diverse palynofloral assemblage of the Cañadón Calcáreo Formation that was once considered to be early Cretaceous in age, is now entirely constrained to the Late Jurassic. [Copyright &y& Elsevier]
