“E-migrantes” y las redes sociales digitales en la construcción de un espacio transnacional: el caso de los peruanos en Portugal
Publication . Marques, João Filipe; Calla Jesús de Sousa, Yesenia
Este artículo busca comprender la influencia de las redes sociales digitales (RSD) en la vida cotidiana de los inmigrantes. Se pretende entender de qué manera estas prácticas contribuyen a la construcción de un espacio transnacional, considerando que esta expresión se refiere al mantenimiento de lazos entre los inmigrantes y su país de origen, así como a la formación de vínculos con sus compatriotas que también viven en el extranjero. El artículo recurre al concepto de “e-migrantes” para designar a aquellos que, mediante el uso de tecnologías de la información y la comunicación (TIC), permanecen conectados entre sí y con su país de origen. Como caso empírico, se estudia a los inmigrantes peruanos residentes en Portugal. La pregunta de investigación fue la siguiente: ¿de qué forma la comunidad peruana que vive en Portugal utiliza las RSD? El artículo se centra en las prácticas que emergen de la apropiación de las plataformas digitales — en particular, la construcción de “comunidades virtuales” — a través de una metodología mixta que incluye el análisis de un conjunto de entrevistas semiestructuradas, una encuesta en línea y datos estadísticos sobre el uso de las RSD.

The North Atlantic is an ocean basin with a diversity of deep-sea ecosystems. Here we provide a summary of the topography and oceanography of the North Atlantic including the Gulf of Mexico and Caribbean Sea, provide a brief overview of the history of scientific research therein, and review the current status of knowledge of each of 18 pelagic and benthic deep-sea ecosystems, with a particular focus on knowledge gaps. We analyse biodiversity data records across the North Atlantic and highlight spatial data gaps that could provide important foci for future expeditions. We note particular data gaps in EEZs of nations within and bordering the Caribbean Sea. Our data provide a baseline against which progress can be tracked into the future. We review human impacts caused by fishing, shipping, mineral extraction, introduction of substances, and climate change, and provide an overview of international, regional and national measures to protect ecosystems. We recommend that scientific research in the deep sea should focus on increasing knowledge of the distribution and the connectivity of key species and habitats, and increasing our understanding of the processes leading to the delivery of ecosystem services. These three pillars - distribution, connectivity, ecosystem function - will provide the knowledge required to implement conservation and management measures to ensure that any deep-sea development in the future is sustainable. Infrastructure and capacity are unevenly distributed and implementation of strategies that will lead to more equitable deep-sea science is required to ensure that essential science can be delivered.
Living on the shores of the Alboran sea. The neolithic on the coast of Málaga (Spain) a multiproxy approach
Publication . Simón-Vallejo, María D.; Lozano-Francisco, M. Carmen; Riquelme-Cantal, José A.; Macías-Tejada, Sara; Camuera, Jon; Uzquiano Ollero, Paloma; Sánchez Marco, Antonio; Garrido-Anguita, Juan M.; Jiménez-Espejo, Francisco; Parrilla-Giráldez, Rubén; Vera-Lozano, José A.; Vera-Peláez, José L.; Cortés-Sánchez, Miguel
Context: The coast of Málaga is one of the core areas for the Neolithic in southern Iberia with the earliest occupations dating to the middle of the 8th millennium cal BP. From the outset, evidence shows a fully developed and highly diversified system of agriculture and animal husbandry. The palaeoenvironmental conditions during this period in the southern Iberian Peninsula reveal phases of aridity.
Objectives: This study aims to understand how Neolithic communities adapted to these adverse environmental conditions. It also explores the role of wild resources and seasonal patterns in subsistence strategies.
Methods: A multiproxy approach was applied, combining regional palaeoenvironmental data with archaeological, archaeofaunal, archaeobotanical and anthropological evidence. The analysis focuses on sites located near aquifer discharges.
Results: Fully developed and highly diversified agriculture and herding practices are documented from the earliest Neolithic phases. The challenges posed by arid conditions appear to have been mitigated by settlement in areas linked to major aquifer outlets and by the cultivation of drought-resistant cereals. Multiple lines of evidence suggest a seasonal pattern of occupation, primarily from late autumn to early summer, when marine resources were likely exploited. Neolithic groups may have engaged in regular hunting and gathering activities or maintained interactions with local Epipalaeolithic–Mesolithic populations. Agricultural and pastoral management emerge as key factors for evaluating the contribution of wild resources to their subsistence.
Conclusions: The integration of environmental, archaeological and biological records provides a more holistic perspective and better understanding of Neolithic economy and society along the Málaga coast between c. 7.6th—5th millennium cal BP, offering insights into subsistence strategies under arid conditions in a coastal setting.
Prioritising research on endocrine disruption in the marine environment: a global perspective
Publication . Pinto, Patricia IS; Miglioli, Angelica; LaLone, Carlie A.; Baumann, Lisa; Baynes, Alice; Blanc‐Legendre, Mélanie; Cancio, Ibon; Cousin, Xavier; Dang, ZhiChao; Dumollard, Rémi; Ford, Alex T.; Green, Christopher; Iguchi, Taisen; Kearney, Philippa; Knigge, Thomas; Minier, Christophe; Monsinjon, Tiphaine; Monteiro, Marta S.; Sturve, Joachim; Watanabe, Haruna; Yamamoto, Hiroshi; Ankley, Gerald; Power, Deborah Mary; Katsiadaki, Ioanna
A healthy ocean is a crucial life support system that regulates the global climate, is a source of oxygen and supports major economic activities. A vast and understudied biodiversity from micro- to macro-organisms is integral to ocean health. However, the impact of pollutants that reach the ocean daily is understudied for marine taxa, which are also absent or poorly represented in regulatory test guidelines for chemical hazard assessment. Inspired by the United Nations Decade of Ocean Science, which aims to reverse the decline in ocean health, this communication calls for global coordination in building resources for studying the effects of marine pollution. The bibliographic analysis, a collective product of scientists from diverse backgrounds, focused on endocrine-disrupting chemicals (EDCs). In this review, we (i) critically analyse the literature on endocrine signalling pathways and high-level physiological impacts of EDCs across 20 representative marine taxa; (ii) identify knowledge and regulatory gaps; (iii) apply bioinformatics approaches to marine species genomic resources, with relevance for predictions of susceptibility; and (iv) provide recommendations of priority actions for different stakeholders. We reveal that the scientific literature on EDCs is biased towards terrestrial and/or freshwater organisms, is limited to a handful of animal taxa, and marine organisms are dramatically underrepresented. Our bibliographic analysis also confirmed that only a small number of (neuro) endocrine pathways are covered for all animals, whilst basic knowledge on endocrine systems/endocrine disruption for most marine invertebrate phyla is minimal. Despite significant gaps in genomic resources for marine animals, endocrine-related protein conservation was evident across more than 500 species from diverse marine taxa, highlighting that they are at risk from EDCs. Despite recent technological advances, translation of existing knowledge into international regulatory test guidelines for chemical hazard assessment and monitoring programs is limited. Furthermore, the current understanding is confounded in part by transposing vertebrate endocrinology onto non-vertebrate taxa. In this context, specific recommendations are provided for all stakeholders, including academia (e.g. to expand knowledge across metazoan taxa and endocrine targets and translate it to New Approach Methodologies and Adverse Outcome Pathways; to increase and improve tools for comparative species-sensitivity distributions and cross-species extrapolations), regulators (e.g. increase awareness of specific risks for the marine environment, prioritise international standardisation of testing methods for marine species and request evidence for absence of endocrine disruption in marine phyla), policy makers (e.g. implement sustained, long-term international marine monitoring programs and increase global co-operation) and the public or non-governmental organisations (e.g. foster public engagement and behaviours that prevent marine chemical pollution; promote citizen science activities; and drive political actions towards protective and restorative marine policies). We hope that this and past reviews can contribute towards meeting ambitious international plans for marine water quality assurance, mitigation of marine pollution impacts and protection of marine biodiversity. The importance of marine biodiversity for climate change mitigation, food security and sustainable ecosystem services calls for urgent, cooperative action.
