Temporal and spatial variations in the quality of water in El Gergal Reservior, Seville, Spain

It is often difficult to define ‘water quality’ with any degree of precision. One approach is that suggested by Battarbee (1997) and is based on the extent to which individual lakes have changed compared with their natural ‘baseline’ status. Defining the base-line status of artificial lakes and reservoirs however, is, very difficult. In ecological terms, the definition of quality must include some consideration of their functional characteristics and the extent to which these characteristics are self-sustaining. The challenge of managing lakes in a sustainable way is particularly acute in semi-arid, Mediterranean countries. Here the quality of the water is strongly influenced by the unpredictability of the rainfall as well as year-to-year variations in the seasonal averages. Wise management requires profound knowledge of how these systems function. Thus a holistic approach must be adopted and the factors influencing the seasonal dynamics of the lakes quantified over a range of spatial and temporal scales. In this article, the authors describe some of the ways in which both long-term and short-term changes in the weather have influenced the seasonal and spatial dynamics of phytoplankton in El Gergal, a water supply reservoir situated in the south of Spain. The quality of the water stored in this reservoir is typically very good but surface blooms of algae commonly appear during warm, calm periods when the water level is low. El Gergal reservoir is managed by the Empresa Municipal de Abastecimiento y Saneamiento (EMASESA) and supplies water for domestic, commercial and industrial use to an area which includes the city of Seville and twelve of its surrounding towns (ca. 1.3 million inhabitants). El Gergal is the last of two reservoirs in a chain of four situated in the Rivera de Huelva basin, a tributary of the Guadalquivir river. It was commissioned by EMASESA in 1979 and since then the company has monitored its main limnological parameters on, at least, a monthly basis and used this information to improve the management of the reservoir. As a consequence of these intensive studies the physical, chemical and biological information acquired during this period makes the El Gergal database one of the most complete in Spain. In this article the authors focus on three ‘weather-related’ effects that have had a significant impact on the composition and distribution of phytoplankton in El Gergal: (i) the changes associated with severe droughts; (ii) the spatial variations produced by short-term changes in the weather; (iii) the impact of water transfers on the seasonal dynamics of the dinoflagellate Ceratium.

Simulations of phytoplankton dynamics in El Gergal Reservoir, Southern Spain (PROTECH)

The Mediterranean region is characterised by a variable climate with most of the rain falling during the winter and frequent summer droughts. Such warm, dry periods are ideal for the growth of large algal blooms that often consist of potentially toxic Cyanobacteria. This makes the management of water for human use particularly challenging in such a climate and it is important to understand how such blooms can be avoided or at least be reduced in size. PROTECH (Phytoplankton RespOnses To Environmental CHange) is a model that simulates the dynamics of different species of phytoplankton populations in lakes and reservoirs. Its distinct advantage over similar models is its ability to simulate the relative composition of the algal flora, allowing both quantitative and qualitative conclusions to be drawn e.g. whether Cyanobacteria could be a potential problem. PROTECH has been applied primarily to lakes and reservoirs in northern Europe. Recently, however, the model has been applied to water bodies in lower latitudes, including Australia to a water supply reservoir in the south of Spain, El Gergal. El Gergal is the last in a chain of reservoirs that supply water to the city of Seville. It was brought into service in April 1979 and has a maximum storage volume of 35 000 000 m3. This article summarises the application of PROTECH in order to simulate the following problems: • the effect of a large influx of Ceratium biomass into El Gergal from another reservoir • the effect of using alternative water sources instead of the Guadalquivir River (used occasionally to raise water levels in El Gergal) • the effect of installing tertiary sewage treatment on the Cala River • the effect of simulated drought conditions on phytoplankton in the reservoir.

Reform of Spain's profesional services market: Implementation of the EU Services Directive

The implementation of the European Commission Services Directive initiated the modernization process of services markets within the European Union. The objective was to guarantee the creation of a single market by ensuring the freedom of establishment and circulation. The transposition of the Directive in Spain triggered an initial wave of reforms in the Spanish legal system. A second package of reforms is currently underway, following recommendations by the EC, IMF and OECD, which highlight the relative lack of competition in Spain���s services as one of the major imbalances in its economy, alongside the public deficit and unemployment. Both the implemented and planned reforms represent a major step forward. Nevertheless, the government has recently announced modifications to the draft bill of the Professional Services and Associations Law, which is expected to soon be submitted for parliamentary debate and approval. Taking into consideration modifications already introduced, together with anticipated further changes, it will be important to maintain the main points of the draft bill and to introduce a deeper review of the legal framework for professional services, of the professional associations themselves, and for the activities that are subject to compulsory membership within a professional association. Spain���s territorial map of professional associations must too be redrawn.

Progressive Decrease in the Potential Usefulness of Meningococcal Serogroup B Vaccine (4CMenB, Bexsero (R)) in Gipuzkoa, Northern Spain

The effectiveness of a vaccine is determined not only by the immunogenicity of its components, but especially by how widely it covers the disease-causing strains circulating in a given region. Because vaccine coverage varies over time, this study aimed to detect possible changes that could affect vaccine protection during a specific period in a southern European region. The 4CMenB vaccine is licensed for use in Europe, Canada, and Australia and is mainly directed against Neisseria meningitidis serogroup B. This vaccine contains four main immunogenic components: three recombinant proteins, FHbp, Nhba and NadA, and an outer membrane vesicle [PorA P1.4]. The allelic distribution of FHbp, Nhba, NadA, and PorA antigens in 82 invasive isolates (B and non-B serogroups) isolated from January 2008 to December 2013 were analyzed. 4CMenB was likely protective against 61.8% and 50% of serogroup B and non-B meningococci, respectively, in the entire period, but between 2012 and 2013, the predicted protection fell below 45% (42.1% for serogroup B isolates). The observed decreasing trend in the predicted protection during the 6 years of the study (X-2 for trend = 4.68, p=0.03) coincided with a progressive decrease of several clonal complexes (e. g., cc11, cc32 and cc41/44), which had one or more antigens against which the vaccine would offer protection.

Ecologia de Tropidurus torquatus (Wied, 1820) (Squamata, Tropiduridae) no Costão de Itacoatiara, Parque Estadual da Serra da Tiririca, municípios de Niterói e Maricá, RJ

O lagarto Tropidurus torquatus (Wied, 1820) possui ampla distribuição geográfica e é encontrado em abundância nas áreas onde ocorre, sendo considerada uma espécie apropriada para estudos ecológicos. No presente estudo nós analisamos o período de atividade, o uso do microhabitat, a intensidade de forrageamento, a dieta e a ecologia térmica de uma população de T. torquatus do Costão de Itacoatiara, no Parque Estadual da Serra da Tiririca, situado nos municípios de Niterói e Maricá, RJ. Os dados foram coletados em dois períodos: entre julho de 2004 e janeiro de 2008 para estudo do período de atividade, uso do microhabitat e intensidade de forrageamento, e entre julho e agosto de 2010 para estudo da ecologia térmica e dieta. Todos os indivíduos coletados eram adultos, com comprimento rostro-cloacal médio de 66,2 12,0mm para machos (n = 11) e 64,1 8,0mm para fêmeas (n = 03). O período de atividade de T. torquatus no Costão de Itacoatiara durou de 12 a 14 horas. Teve um padrão unimodal na estação seca, com pico de atividade entre 09:00h e 13:00h, durante as horas mais quentes do dia. Na estação chuvosa o padrão de atividade foi bimodal, com um pico entre 8:00h e 9:00h e outro entre 16:00h e 17:00h, ambos associados aos horários de temperaturas ambientais mais amenas. O período de atividade não diferiu entre as estações, o que pode ser explicado pelo extenso pico de atividade dos lagartos na estação seca. Os microhabitats mais utilizados foram o substrato rochoso do Costão e a bromélia, refletindo a disponibilidade destes na área. A intensidade de forrageamento não diferiu sazonalmente e o tempo médio que os lagartos ficaram parados foi maior do que o tempo médio em deslocamento. A dieta foi onívora e esteve composta por artrópodes, principalmente insetos, e material vegetal, principalmente frutos. Os principais insetos consumidos foram Formicidae, Coleoptera e Hymenoptera não-Formicidae como pequenas vespas e abelhas. Os frutos, as sementes e as flores consumidos pertenciam às cactáceas Rhipsalis cereoides e Coleocephalocereus fluminensis, para as quais T. torquatus pode ser um potencial agente dispersor de sementes na área. Lagartos maiores consumiram itens maiores, mas em menor número, indicando um balanço energético positivo. O consumo de material vegetal variou de acordo com o tamanho dos lagartos, aumentando sua proporção nos indivíduos mais velhos. A temperatura média em atividade de T. torquatus foi de 34,3 2,5C, estando na faixa de temperatura corpórea média encontrada para outras populações e para outros Tropidurus. O substrato foi a fonte de calor ambiental com maior importância relativa para a termorregulação dos lagartos durante a estação seca, explicando cerca de 48% da variação na temperatura corpórea da população. Os lagartos termorregularam de forma passiva, principalmente em relação à temperatura do substrato.

Dimorfismo sexual e polimorfismo no gênero Ptychoderes Schoenherr, 1823 (Coleoptera Anthribidae, Anthribinae, Ptychoderini)

O dimorfismo sexual exibido por machos polifênicos em algumas espécies do gênero Ptychoderes envolve variação no rostro, antena e ventritos. A existência de polifenismo pode ser um importante componente no processo evolutivo por meio de novidades morfológicas e comportamentais. O objetivo desse estudo foi determinar a variação em caracteres morfométricos, polifenismo em machos, variação de estruturas com conhecido dimorfismo sexual, possíveis padrões alométricos e testar estas inferências para Ptychoderes através do mapeamento do dimorfismo sexual e de machos em uma reconstrução filogenética de Ptychoderes usando Mesquite 2.04. Foram medidas 23 variáveis morfométricas em 510 espécimes com as seguintes análises realizadas: análises de cluster, analises de componentes principais (PCA), analise de variáveis canônicas (AVC), análise de regressão por eixo maior reduzido (RMA). Cada tipo de dimorfismo foi mapeado em uma filogenia prévia como dois estados separados usando parcimônia. Para todas as espécies o dimorfismo sexual apresentou diferenças significativas entre os sexos com relação aos segmentos antenais (II- X).O compriemtno do rosto e ventrito V foram confirmados como indicativos de dimorfismo sexual (exceto em P. jordani). A única espécie em que não ocorreu machos polifenicos foi P. depressus. Nas outras espécies machos grandes e pequenos diferem significantemente para muitas variáveis com similaridades e diferenças. Na ACP, o primeiro componente (PC1) apresentou alta porcentagem de variância nos dados de todas as espécies; apresentou loadings de mesmo sinal sugerindo diferenças relacionadas ao tamanho para as espécies P. jordani, P. depressus, P. virgatus, P. mixtus e P. callosus e para as espécies P. viridanus, P. antiquus, P. elongates e P. nebulosus apresentou loadings positivos e negativos sugerindo diferenças relacionadas a forma (alometria). O PC2 apresentou loadings positivos e negativos para todas as espécies, um provável componente alométricos. A AVC confirmou os grupos: machos grandes, machos pequenos e fêmeas quando estes ocorreram. Nós encontramos diferentes padrões alométricos para todas as espécies com diferenças e semelhanças entre as espécies. Todos esses resultados confirmam a hipótese de polifenismo em machos e dimorfismo sexual para Ptychhoderes. A análise dos padrões alométricos para o dimorfismo sexual revelou alometria positiva para o comprimento do rostro (CR1) em machos e fêmeas, com os ventritos apenas em machos. Padrões alométricos positivos relacionados ao polifenismo nos antenômeros foram confirmados para os machos grandes e pequenos de quase todas as espécies exceto em P. nebulosus. O ancestral de clados na filogenia de Ptychoderes foi inferido para machos polifênicos (exceto P. depressus) com variáveis no rostro, antenas e ventritos indicativas de dimorfismo sexual com alometria positiva. Estes padrões poderiam estar ligados com o comportamento de proteção das fêemeas realizados por machos grandes durante a oviposição.

The impact of the great recession on employment polarization in Spain

This article analyzes changes in the occupational employment share in Spain for the period 1997-2012 and the way particular sociodemographic groups adapt to those changes. There seems to be clear evidence of employment polarization between 1997 and 2012 that accelerates over the recession. Changes in the composition of the labour supply cannot explain the increase in the share of occupations at the low end of the wage distribution. Sector reallocation may have partially contributed to explain the polarization process in Spain during the years of expansion (1997-2007) but it is a minor factor during the recession. The polarization of occupations within sectors observed, especially during the recession, appears to be related to a decline in routine tasks which is compensated by an increase in occupations with non-routine service contents, which are found both in the low and high end of the wage distribution. Instead, jobs with a higher degree of abstract contents do not appear to increase their share in total employment during these 15 years. The paper finds that this process has affected males more strongly than females because of their higher concentration in occupations more focused on routine tasks. Among males, for workers under 30 years old, we find a decrease in the share of occupations with more routine tasks which turns into increases in those with more abstract content and particularly with more non-routine service content. Instead, male workers over 30 years old seem to remain in declining occupations to a greater extent. Females of different ages are not affected by the abovementioned changes.

Spatial-temporal excess mortality patterns of the 1918-1919 influenza pandemic in Spain

Background: The impact of socio-demographic factors and baseline health on the mortality burden of seasonal and pandemic influenza remains debated. Here we analyzed the spatial-temporal mortality patterns of the 1918 influenza pandemic in Spain, one of the countries of Europe that experienced the highest mortality burden. Methods: We analyzed monthly death rates from respiratory diseases and all-causes across 49 provinces of Spain, including the Canary and Balearic Islands, during the period January-1915 to June-1919. We estimated the influenza-related excess death rates and risk of death relative to baseline mortality by pandemic wave and province. We then explored the association between pandemic excess mortality rates and health and socio-demographic factors, which included population size and age structure, population density, infant mortality rates, baseline death rates, and urbanization. Results: Our analysis revealed high geographic heterogeneity in pandemic mortality impact. We identified 3 pandemic waves of varying timing and intensity covering the period from Jan-1918 to Jun-1919, with the highest pandemic-related excess mortality rates occurring during the months of October-November 1918 across all Spanish provinces. Cumulative excess mortality rates followed a south-north gradient after controlling for demographic factors, with the North experiencing highest excess mortality rates. A model that included latitude, population density, and the proportion of children living in provinces explained about 40% of the geographic variability in cumulative excess death rates during 1918-19, but different factors explained mortality variation in each wave. Conclusions: A substantial fraction of the variability in excess mortality rates across Spanish provinces remained unexplained, which suggests that other unidentified factors such as comorbidities, climate and background immunity may have affected the 1918-19 pandemic mortality rates. Further archeo-epidemiological research should concentrate on identifying settings with combined availability of local historical mortality records and information on the prevalence of underlying risk factors, or patient-level clinical data, to further clarify the drivers of 1918 pandemic influenza mortality.

Genotypes, Recombinant Forms, and Variants of Norovirus GII.4 in Gipuzkoa (Basque Country, Spain), 2009-2012

Background: Noroviruses (NoVs) are genetically diverse, with genogroup II-and within it-genotype 4 (GII.4) being the most prevalent cause of acute gastroenteritis worldwide. The aim of this study was to characterize genogroup II NoV causing acute gastroenteritis in the Basque Country (northern Spain) from 2009-2012. Methods: The presence of NoV RNA was investigated by reverse transcriptase-polymerase chain reaction (RT-PCR) in stool specimens from children younger than 15 years old with community-acquired acute gastroenteritis, and from hospitalized adults or elderly residents of nursing homes with acute gastroenteritis. For genotyping, the open reading frames ORF1 (encoding the polymerase) and ORF2 (encoding the major capsid protein) were partially amplified and sequenced. Recombinant strains were confirmed by PCR of the ORF1/ORF2 junction region. Results: NoV was detected in 16.0% (453/2826) of acute gastroenteritis episodes in children younger than 2 years, 9.9% (139/1407) in children from 2 to 14 years, and 35.8% (122/341) in adults. Of 317 NoVs characterized, 313 were genogroup II and four were genogroup I. The GII.4 variants Den Haag-2006b and New Orleans-2009 predominated in 2009 and 2010-2011, respectively. In 2012, the New Orleans-2009 variant was partially replaced by the Sydney-2012 variant (GII.Pe/GII.4) and New Orleans-2009/Sydney-2012 recombinant strains. The predominant capsid genotype in all age groups was GII.4, which was the only genotype detected in outbreaks. The second most frequent genotype was GII.3 (including the recently described recombination GII.P16/GII.3), which was detected almost exclusively in children. Conclusion: Nine different genotypes of NoV genogroup II were detected; among these, intergenotype recombinant strains represented an important part, highlighting the role of recombination in the evolution of NoVs. Detection of new NoV strains, not only GII.4 strains, shortly after their first detection in other parts of the world shows that many NoV strains can spread rapidly.
