El presente trabajo, ha tratado de evidenciar la relación directa entre los factores de flexibilización del marco de la contratación temporal y la tasa de desempleo, a través del estudio jurídico temporal de las reformas legislativas en este ámbito, y de los resultados prácticos de las mismas. Se ha detectado un alto grado de fraude de ley, y una clara incidencia en la base de nuestro modelo productivo, carente de valor añadido, bulímico, con capacidad de absorber grandes flujos de trabajo y reducir el desempleo para posteriormente vomitar más de esa absorción, con el consecuente aumento del desempleo. Finalmente, se apuntan en el apartado de conclusiones algunas propuestas para romper esa inercia generada por el binomio objeto del estudio. ; The present work, has tried to demonstrate the direct relationship between the factors of flexibility in the context of temporary employment and unemployment, through the temporary study of legislative reforms in this area, and the practical results thereof. We detected a high degree of fraud, and a clear impact on the basis of our production model, with no value added, bulimic, capable of absorbing large workflows and reduce unemployment to throw more of that later absorption with the consequent rise in unemployment. Finally, we indicate in the concluding section, some proposals to break the inertia generated by the pair under study.

We aimed to show how the predicted pH decrease in the ocean would alter the toxicity, bioconcentration and dietary transfer of trace metal copper on seagrass ecosystems, on a short-term basis. Seagrass Zostera noltei was exposed to two pH levels (8.36 and 8.03) and three copper levels (nominal concentrations, < 3, 30 and 300 mu g Cu L-1) in a factorial design during 21 days, while Gammarus Iocusta amphipods were continuously fed with the treated seagrass leaves. We found that the toxicity and bioconcentration of copper in seagrasses were not affected by pH, yet complex copper-pH interactions were observed in the seagrass photosynthesis. We demostrated that seagrasses can act as a copper source in the food web via direct consumption by herbivores. Future research need to investigate the interactive effects on a long-term basis, and to include biochemical and molecular endpoints to provide additional insights to the complex phisiological interactions observed. ; project "Ecological risk assessment of oils and hazardous and noxious substances in the NW Portuguese coast (ECORISK)" - North Portugal Regional Operational Programme (ON.2-O Novo Norte), under the National Strategic Reference Framework (NSRF) [NORTE-07-0124-FEDER-000054] ; European Regional Development Fund (ERDF)European Union (EU) ; Portuguese Science and Technology FoundationPortuguese Foundation for Science and Technology [SFRH/BPD/119344/2016, SFRH/BPD/77912/2011] ; ARCOPOL plus - Improving maritime safety and pollution response through technology transfer, training & innovation project [2011-1/150]

SIMPLE SUMMARY: The Mediterranean Basin is the second largest citrus-producing region in the world. Huanglongbing (HLB) is the most important and devastating citrus disease worldwide, the causal agents of which are three bacteria species that belong to the genus Candidatus Liberibacter. The main transmission of these three bacteria is by two psyllid vectors, Diaphorina citri and Trioza erytreae. Trioza erytreae is a specific pest of plants from the Rutaceae family, which includes cultivated citrus. This insect has recently been detected in Mediterranean Basin countries, such as Spain and Portugal, but none of the causal agents of HLB have been described as infecting citrus plants in this region. The potential risk of HLB emergence has increased concern in the Spanish and Portuguese citrus industries, which require novel methods for controlling/eradicating populations of T. erytreae that are environmentally sound under new pesticide restrictions from European Union authorities. Hence, psyllid rootstock feeding preferences could play an important role in pest management. Thus, different citrus rootstocks have been tested for feeding, oviposition, and survival of T. erytreae. This study reports that the most commonly used citrus rootstocks (Carrizo citrange and Citrus macrophylla) are the favorite choices for the development of T. erytreae, and by contrast Poncirus trifoliata is the least suitable for this insect vector. ABSTRACT: Trioza erytreae (Del Guercio, 1918) (Hemiptera: Triozidae) is a vector of Candidatus Liberibacter spp., the causal agent of Huanglongbing disease (HLB). This study evaluates the preference of T. erytreae in different citrus seedlings. Thus, six different non-grafted citrus rootstocks were used for these experiments: (a) Carrizo citrange; (b) Citrus macrophylla; (c) 'Cleopatra' mandarin; (d) Forner-Alcaide No. 5; (e) Forner-Alcaide No. 517, and (f) Poncirus trifoliata ('Flying Dragon'). The behaviour and survival of this psyllid was evaluated through the feeding preference of T. erytreae ...

Plastics is all the rage, and mitigating marine litter is topping the agenda for nations pushing issues such as ocean acidification, or even climate change, away from the public consciousness. We are personally directly affected by plastics and charismatic megafauna is dying from it, and it is something that appears to be doable. So, who cares about the issue of ocean acidification anymore? We all should. The challenge is dual in the fact that is both invisible to the naked eye and therefore not felt like a pressing issue to the public, thereby not reaching the top of the agenda of policy makers; but also that it is framed in the climate change narrative of fear - whereby it instills in a fight-or-flight response in the public, resulting in their avoidance of the issue because they feel they are unable to take action that have results. In this article, we argue that the effective global environmental governance of ocean acidification, though critical to address, mitigate against and adapt to, is hindered by the both this lack of perception of urgency in the general public, fueled by a lack of media coverage, as well as a fight-or-flight response resulting from fear. We compare this to the more media friendly and plastics problem that is tangible and manageable. We report on a media plots of plastics and ocean acidification coverage over time and argue that the issue needs to be detangled from climate change and framed as its own issue to reach the agenda at a global level, making it manageable to assess and even care about for policy makers and the public alike? ; Who cares about ocean acidification in the Plasticene? ; Funded by the Horizon 2020 Framework Programme of the European Union. ; publishedVersion

The decline of freshwater biodiversity hás reached alarming proportions. The extinction rate of freshwater biodiversity is predicted to be five times faster than ali other groups of species. The Unionidae, being the largest of the freshwater bivalve families, is among the most endangered group in the world. They are important providers of aquatic ecosystem services and are characterized by an unusual pattem of mtDNA inheritance. However, phylogeny, population genetic structure and species-level diversity remains unclear for much of the group. With an experienced and well-qualified team, the present proposal aims to define the most important freshwater mussel taxa and most criticai áreas for conservation, at European and Global leveis, to inform the most relevant policy niakers. This will be achieved by integrating a genomics approach with available distribution data, in order to determine and map global species richness, phylogenetic diversity, and weighted endemism. This complementary approach will not only help conserve this vulnerable group but will offer wider benefits to freshwater ecosystems whose billions of people depend globally. Additionally, as these animals have an extraordinary unusual pattern of mtDNA inheritance, they will be used as model-taxa to study the evolution of mtDNA and life in general. ; This research was developed under Project Nº NORTE-01-0145-FEDER-030286 (ConBiomics: the missing approach for the Conservation of freshwater Bivalves), co-financed by COMPETE 2020, Portugal 2020 and the European Union through the ERDF, and by FCT through national funds. ; info:eu-repo/semantics/publishedVersion
