Clínica e cirurgia de pequenos animais

Este relatório foi elaborado na sequencia do estágio curricular realizado pelo autor, ente 28 de setembro de 2015 e 28 de março de 2016, no Hospital Clínico Veterinario de la Universidad CEU Cardenal Herrera (HCV CEU-UCH), em Alfara del Patriarca, Valência, Espanha. A infeciologia foi a área da clínica médica mais representativa (28%), sendo o vírus da imunodeficiência felina (FIV) o agente infecioso registado mais frequentemente (19%). É importante reconhecer e diagnosticar esta infeção de forma a aplicar um maneio adequado aos pacientes infetados, melhorando a sua qualidade de vida e prevenindo a propagação do vírus. A infeção provocada pelo FIV raramente provoca uma síndrome severa, porém, várias alterações podem decorrer. Apesar do FIV provocar uma infeção crónica, com os cuidados adequados, os pacientes infetados poderão viver vidas longas, com uma boa qualidade de vida, e eventualmente acabar por morrer de causas não relacionadas com o FIV; Abstract: Small Animal Medicine and Surgery This report was elaborated following the externship performed by the author, between September 28th 2015 and March 28th 2016, at the Hospital Clínico Veterinario de la Universidad CEU Cardenal Herrera (HCV CEU-UCH), in Alfara del Patriarca, Valencia, Spain. The most frequent specialty field within the area of internal medicine was infectiology (28%), with feline immunodeficiency virus (FIV) being the infectious agent most frequently registered (19%). It is important to recognize and diagnose the infection caused by this agent accurately, so that the right measures of management can be applied, improving the life’s quality of the patient and reducing the risk of viral spreading. The infection by FIV rarely produces a severe syndrome, however many clinicopathologic disorders may occur. FIV causes a chronic infection, however, with the proper care, the infected cats may live long lives, with a fair quality, eventually ending up dying from causes unrelated to FIV.

Fine-scale estimations of bioclimatic change in the Valencia region, Spain

Recent advances in statistical downscaling have allowed the reconstruction of temperatures for the complete 1948–2011 period in a spatial resolution of 90 m and without gaps for the Valencian Community (Spain) and bordering areas. It presently enables analyses in this region, which allows the determination of recent temperature changes at subregional and local scales. The present work focuses on obtaining the thermicity index according to Rivas-Martínez, a well-known indicator of different thermotypes associated with bioclimatic horizons. The change in this index, which has happened in the region between 1948 and 2011, was calculated by generating fine-scale maps of the potential extension of different thermotypes. The results show a greater regression for the thermotypes in a finicolous position, e.g. Orotemperate, Supratemperate and Supramediterranean horizons, which herein indicate greater potential vulnerability in climate change. In the absence of, and given the need for, such fine-scale information, this work should be useful for specialized researchers to spatially limit the potentially most vulnerable biotopes to climate change.

Diagenetic processes in a partially dolomitized carbonate reservoir: Casablanca oil field, Valencia Trough, offshore Spain.

Mesozoic and Neogene carbonates located in the Valencia Trough (offshore Spain, western Mediterranean Sea)are oil reservoirs. This paper investigates the diagenetic evolution of the Upper Jurassic limestones, currently dolomitized, that constitute the main reservoir of the Casablanca oil field. Core samples from Casablanca-1A well have been studied to determine the diagenetic products and their relation with porosity evolution, and to reconstruct the fluid flow history prior to and during oil emplacement. On the basis of petrological observations and geochemical analyses (major, minor and trace element composition and oxygen, carbon and strontium isotope composition), a major dolomitization event is recognized postdating subaerial exposure, erosion and karstification. The dolomitization event originated two replacive dolomites (RD1 and RD2) and two dolomite cements (saddle dolomite cement, SDC, and milky-white dolomite cement, MDC)which are partially cogenetic. RD1, RD2 and SDC precipitated at increasing temperatures (over 60ºC and below 110ºC), probably from meteoric water mixed with marine water. The last dolomite type milky-white dolomite cement) precipitated with increasing burial conditions and by arrival of hydrothermal fluids during the Miocene. The post-dolomitization sequence comprises precipitation of calcite cement and partial calcitization of all previous dolomites. The oxygen, carbon and strontium isotope compositions suggest that this calcite cementation occurred from meteoric waters mixed with Burdigalian - Langhian marine waters trapped in the sediments and expelled by compaction in the moderate to deep burial realm. Normal faults were the conduits for upward migration of these fluids as well as for later oil expulsion from the Burdigalian - Langhian source rocks. Late corrosion associated with organic acid-enriched fluids took place prior or simultaneously to oil migration during the Pliocene, enhancing porosity and increasing eservoir quality.

Women's Songs. The Lullaby in the Spanish Autonomous Region of Valencia

A lullaby is a song performed almost exclusively by women in all cultures to make children fall asleep. But traditional lullaby singing has declined due to social change. This study analyzes its structure and content thoroughly and aspects of this tradition providing information on usage, customs, themes and types of melody, and reflecting the importance of this form of cultural expression.

Decreasing fires in a Mediterranean region (1970-2010, NE Spain)

We analyse the recent evolution of fires in Catalonia (north-eastern Iberian Peninsula), a typical Mediterranean region. We examine a homogeneous series of forest fires in the period 1970-2010. During this period, more than 9000 fire events greater than 0.5 ha were recorded, and the total burned area was more than 400 kha. Our analysis shows that both the burned area and number of fire series display a decreasing trend. Superposed onto this general decrease, strong oscillations on shorter time scales are evident. After the large fires of 1986 and 1994, the increased effort in fire prevention and suppression could explain part of the decreasing trend. Although it is often stated that fires have increased in Mediterranean regions, the higher efficiency in fire detection could have led to spurious trends and misleading conclusions.

The local population and museums. An analysis based on the use of museums in the Alt Pirineu and Aran Region (Catalonia, Spain)

His paper is based on a study of visitors to the museums in the Alt Pirineu and Aran region (Catalonia, Spain). We describe the characteristics of the museums’ users and analyse the relationship between the museums and the local community. We highlight the importance of these facilities for local development, and the need to consider and prioritize their role as culture centres for the region’s population.

Producing Inequalities: Regional Sequences in Later Prehistoric Southern Spain

This paper presents regional sequences of production, consumption and Social relations ill Southern Spain from the beginning of the Neolithic to the Early Bronze Age (c. 5600-1550 BC). The regions Studied are southeast Spain, Valencia, the southern Meseta and central/western Andalucia. The details presented for each region and period vary in quality but Show how Much our knowledge of the archaeological record of southern Spain has changed during the last four decades. Among the Surprises are the rapidity of agricultural adoption. the emergence of regional centres of aggregated population in enclosed/fortified settlements of up to 400 hectares in the fourth and third millennia BC. the use of copper objects as instruments of production, rather than as items With 11 purely symbolic of 'prestige' value, large-scale copper production in western Andalucia in the third millennium BC (as opposed to the usual domestic production model), and the inference of societies based oil relations of class.

Study of packing lines for stone fruits and citrus using two instrumented spheres in some cooperatives in the region of Murcia (Spain).

Two instrumented spheres IS 100 were used to evaluate the quality of post-harvest operations. Results obtained from measurements made with both IS (8.8 cm 0 and 6.2 cm 0) show significant differences. Both IS measure the same values of the same variables for soft materials, but not for hard surfaces. Four packing lines belonging to different cooperatives of the region of Murcia (two for stone fruits and two for citrus) were tested. IS values obtained in transfers belonging to the tested lines lay well above 50 g's in most of them Much higher impact intensities are registered in citrus lines than in stone fruit packing lines. To study the incidence of a certain packing line on different products an interaction fruit-packing line test was perf01med. In all cases, more than 50% of fruits belonging to the post-handling sample showed some kind of damage. Bruises evolve after 48 hours storage at room temperature.

Exploring public support for climate change adaptation policies in the Mediterranean region: A case study in Southern Spain.

The understanding of public perception to climate change is an essential factor in the development of adaptation policies. In the Mediterranean, agriculture, as the largest consumer of freshwater, has the highest potential to suffer adverse impacts of climate change. Future water availability predictions, conflicting interests among stakeholders and an increasing social concern about the environment further aggravate the situation. Therefore studying public support for adaptation policies can play a key role in successfully adapting the sector. The study site, approximately 36,000 hectares of rice fields in Seville (Spain), exemplifies an area in the Mediterranean where water needs to be carefully re-allocated in view of the limitations anticipated by climate change scenarios; in particular where conflicts will arise between water for agriculture and water for ‘natural’ ecosystems. This paper proposes an ex-ante evaluation of the societal support for adaptation policies. A survey of 117 respondents was conducted and a Logit model utilized to analyze which predictors positively or negatively affect people's support for adaptation policies. Results suggest that the main barriers to support these policies were economic losses and low climate change concern whereas the primary motivation factor was environmental commitment. Additionally, the main socio-demographic determinants were gender, age, education and family structure. In order to improve societal support for climate change adaptation policies, implementing educational and awareness raising initiatives will be the main challenges for policy makers to overcome.

Enhanced radon emission in natural CO2 flows in Campo de Calatrava region (central Spain)

Activity of radon gas in natural soils is commonly low (in the order of few thousands of Bq·m-3) due to the fast decay (half-life= 3.8 days in the case of 222Rn) that prevents accumulation in soil pores. Exceptionally, high Rn soil activity (up to 430 KBq·m-3) is found around point sources of deep CO2 fluxes. These fluxes allow the transport of trace gases (including Rn) to long distances in the geosphere leading to a potential hazard as Rn accumulation in buildings. CO2 degassing is common in active or ancient volcanic fields and occurs as free gas fluxes or dissolved in groundwater. In this work, the occurrence of Rnbearing, CO2 fluxes from the Campo de Calatrava region in Central Spain has been studied in order to determine their (1) magnitude, (2) migration paths and (3) potential impact on the environment, and (4) methodologies to best detection and measurement.

Native bradyrhizobial symbionts of Lupinus mariae-josephae, a unique endemism thriving in alkaline soils in Eastern Spain

Lupinus mariae-josephae (Lmj) es una especie de lupino endémica de una pequeña y específica área de Comunidad Valenciana (Este de España), donde prospera en suelos alcalinoscalcáreos, un hábitat singular para los altramuces, que crecen preferentemente en suelos ácidos o neutros. Esto hace de Lmj una especie de lupino única. Cuando se inició este trabajo, la extensión conocida de este endemismo abarcaba unos 700 kilómetros cuadrados, confinados en la provincia de Valencia. En esta área, Lmj prospera en pequeñas poblaciones aisladas que contienen un número reducido de plantas por lo que se la consideró una especie en peligro de extinción. Todos los esfuerzos, utilizando estrategias clásicas dirigidas a ampliar el área de crecimiento de Lmj y garantizar su conservación, han tenido un éxito limitado. El trabajo que se presenta está dirigido a mejorar el conocimiento de la ecología de Lmj, en particular la interacción simbiótica que establece con bacterias del suelo denominadas rizobios y se centra en la caracterización fenotípica, filogenética y genómica de esos rizobios. También se investiga la posible contribución de la simbiosis en mejorar la conservación de Lmj. Para este fin, se han estudiado diferentes aspectos que se describen a continuación. El primero objetivo se centró en aislar y estudiar de la diversidad genética de las bacterias endosimbióticas de Lmj. . Se realizó un análisis filogenético de genes esenciales que mostró que las cepas de Lmj pertenecen al género Bradyrhizobium y que presentan una gran diversidad con características fenotípicas y simbióticas diferentes de cepas de Bradyrhizobium que nodulan otras especies de lupinos nativos de España (cepas ISLU). Las cepas estudiadas se dividieron en dos grupos (Clado I y Clado II). El Clado I, incluye a las cepas Lmj, definiendo un nuevo linaje, filogenéticamente relacionado con otras especies de Bradyrhizobium, como B. jicamae y B. elkanii. El Clado II contiene cepas ISLU relacionadas con cepas de B. canariense y B. japonicum que establecen simbiosis con lupinos de suelos ácidos. Otro análisis filogenético basado en genes simbióticos, distribuyó las cepas de Lmj en sólo dos grupos diferentes. La singularidad y gran diversidad de estas cepas en una pequeña área geográfica, hacen de este, un atractivo sistema para el estudio de la evolución y adaptación de las bacterias simbióticas a su respectiva planta huésped. Adicionalmente, se estudio la presencia de bacterias capaces de nodular Lmj en suelos básicos de Chiapas, México. Sorprendentemente, estos suelos contienen bacterias capaces establecer interacciones simbióticas eficientes con Lmj en ensayos de invernadero. A continuación se investigó la taxonomía de los endosimbiontes de Lmj analizando la secuencia de cuatro genes esenciales (16S rRNA, recA, glnII y atpD) y el promedio de identidad de nucleótidos de genomas completos de algunas cepas representativas de la diversidad (ANIm). Se identificaron nuevas especies de Bradyrhizobium dentro del Clado I y se definió una de ellas: 'Bradyrhizobium valentinum' sp. nov (cepa tipo LmjM3T = CECT 8364T, LMG 2761T). También se abordó cómo conservar Lmj en su hábitat natural mediante inoculación con alguna de las cepas aisladas. Se demostró la ausencia de bacterias capaces de nodular Lmj en suelos rojos alcalinos o ‘‘terra rossa’’ de la Península Ibérica y Baleares. Dos cepas, altamente eficientes en cuanto a la fijación de nitrógeno, LmjC y LmjM3T, fueron seleccionadas para ser empleadas como inoculantes. Dos experimentos de campo llevados a cabo en años consecutivos en áreas con características edafoclimáticas similares a las que presentan las poblaciones de Lmj, lograron la reproducción exitosa de la planta. Se concluyó que un ciclo reproductivo exitoso de Lmj es absolutamente dependiente de la inoculación con sus simbiontes naturales y que la simbiosis debe ser considerada un factor esencial en estrategias de conservación de leguminosas en peligro. La obtención de varias secuencias genómicas de cepas aisladas de Lmj y de otras cepas de Bradyrhizobium reveló una alta similitud entre los genomas de las cepas del Clado I, y permitió la identificación de cinco posibles nuevas especies. Además, se estudiaron tres agrupaciones de genes relacionados con la simbiosis (nod, nif y fix) definiendo un nuevo linaje para las cepas de Lmj, diferente del symbiovar “genistearum” de B. canariense y B. japonicum. La baja diversidad encontrada en el análisis filogenético de los genes simbióticos contrasta con la gran diversidad asociada a genes esenciales. La presencia de plásmidos en cepas del género Bradyrhizobium ha sido descrita en muy pocas ocasiones, sin embargo el análisis de la secuencia genómica de la cepa ISLU101, aislada de Lupinus angustifolius, reveló la presencia de un origen de replicación extracromosómico homólogo al operón repABC, presente en el plásmido de Bradyrhizobium sp BTAi1. Gracias a esta secuencia se identificaron genes homólogos en 19 de 72 cepas ISLU. Filogenéticamente, las secuencias de repABC se agruparon en un grupo monofilético con las de pBTAi1 y separadas de los rizobios de crecimiento rápido. Finalmente, se identificaron sistemas de secreción de proteínas de tipo III (T3SS) en nueve genomas de cepas de Lmj. Los T3SS pueden inyectar proteínas efectoras al interior de células vegetales. Su presencia en rizobios se ha relacionado con la gama de hospedador que pueden nodular y puede tener un efecto beneficioso, neutro o perjudicial en la simbiosis. Los T3SS de las cepas de Lmj codifican para una proteína efectora similar a NopE, un efector dependiente de T3SS descrito en B. diazoefficiens USDA 110T. La proteína NopE de la cepa LmjC se ha caracterizado bioquímicamente. ABSTRACT Lupinus mariae-josephae (Lmj) is a lupine species endemic of a unique small area in Valencia region (Eastern Spain) where the lupine plants thrive in alkaline-limed soils, which preferentially grow in acid or neutral soils. This is the type of soils native lupines of Spain. When this work was initiated, the extension of the endemic area of Lmj was of about 700 squared kilometers confined to the Valencia province. In this area, Lmj thrives in small, isolated patches containing a reduced number of plants, and points to an endemism that can easily became endangered or extinct. Consequently, the Valencia Community authorities gave a ‘‘microreserve” status for conservation of the species. All efforts, using classical strategies directed to extend the area of Lmj growth and ensure its conservation have been so far unsuccessful. The work presented here is directed to improve our knowledge of Lmj ecology and it is centered in the characterization of the rhizobial symbiosis by phenotypic, phylogenetic and genomic analysis as well as in investigate the potential contribution of the symbiosis to improve its conservation. To this end, five different topics have been studied, and results are briefly described here. Extensive details can be followed en the attached, published articles. The first topic deals with the indigenous rhizobial symbionts of the Lmj endemism, and its genetic diversity was investigated. The Lmj root symbionts belong to the Bradyrhizobium genus, and phylogenetic analysis based on core genes identified a large diversity of Bradyrhizobium strains with phenotypic and symbiotic characteristics different from rhizobia nodulating other Lupinus spp. native of Spain. The strains were split in two clades. Clade II contained strains close to classical B. canariense and B. japonicum lineages that establish symbioses with lupines in acid soils of the Mediterranean area. Clade I included Lmj strains that define a new lineage, close to other Bradyrhizobium species as B. jicamae and B. elkanii. The phylogenetic analysis based on symbiotic genes identified only two distinct clusters. The singularity and large diversity of these strains in such a small geographical area makes this an attractive system for studying the evolution and adaptation of the rhizobial symbiont to the plant host. Additionally, the presence of bacteria able to nodulate Lmj in basic soils from Chiapas, Mexico was investigated. Surprisingly, these soils contain bacteria able to effectively nodulate and fix nitrogen with Lmj plants in greenhouse assays. In the second topic, the taxonomic status of the endosymbiotic bacteria of Lmj from Valencia endemism and Chiapas was investigated. Results from phylogenetic analysis of core genes and Average Nucleotide Identity (ANIm) using draft genomic sequences identified new Bradyrhizobium species within strains of Clade I of Lmj endosymbiotic bacteria. Only one of these potentially new species has been defined, meanwhile the others are under process of characterization. The name ‘Bradyrhizobium valentinum’ sp. nov. was proposed for the defined species (type strain LmjM3T= CECT 8364T, LMG 2761T). The third topic was directed to conservation of endangered Lmj in its natural habitat. The relevant conclusion of this experimentation is that the symbiosis should be considered as a relevant factor in the conservation strategies for endangered legumes. First, we showed absence of bacteria able to nodulate Lmj in all the inspected ‘‘terra rossa’’ or alkaline red soils of the Iberian Peninsula and Balearic Islands. Then, two efficient nitrogen fixing strains with Lmj plants, LmjC and LmjM3T, were selected as inoculum for seed coating. Two planting experiments were carried out in consecutive years under natural conditions in areas with edapho-climatic characteristics identical to those sustaining natural Lmj populations, and successful reproduction of the plant was achieved. The relevant conclusion from these assays was that the successful reproductive cycle was absolutely dependent on seedling inoculation with effective bradyrhizobia The forth topic deep into the analysis of the genomic of Lmj representative strains. To this end, draft genomic sequences of selected Lmj strains and type strains of Bradyrhizobium spp. were assembled. The comparison analysis of the draft genomic sequences of Lmj strains and related Bradyrhizobium species grouped in Clade I, revealed a high genomic homology among them, and allowed the definition of five potentially new species of Lmj nodulating bacteria. Also, based on the available draft genomic sequences, only three clusters of nod, fix and nif genes from Lmj strains were identified and showed to define a new symbiotic lineage, distant from that of B. canariense and B. japonicum bv. genistearum. The low diversity exhibited by the phylogenetic analysis of symbiotic genes contrast with the large diversity of strains as regards the housekeeping genes analyzed. Besides, the genomic analysis of a Lupinus angustifolius strain ISLU101, revealed the presence of an extrachromosomal replication origin homologous to repABC cluster from plasmid present in Bradyrhizobium spp BTAi1. This repABC cluster gene sequence allowed the identification of extrachromosomic replication origin in 19 out of 72 Bradyrhizobium strains from Lupinus spp., a highly significant result since the absence of plasmids in the Bradyrhizobium genus was traditionally assumed. The repABC gene sequences of these strains grouped them in a unique monophyletic group, related to B. sp. BTAi1 plasmid, but differentiated from the repABC gene cluster of plasmids in fast growing rhizobium strains. The last topic was focused on characterization of type III secreted effectors present in Lmj endosymbiotic bacteria. Type III secretion systems (T3SS) are specialized protein export machineries which can deliver effector proteins into plant cells. The presence of T3SS in rhizobia has frequently been related to the symbiotic nodulation host-range and may have a beneficial or detrimental effect on the symbiosis with legumes. In this context, the presence of T3SS in genomes of nine Lmj strains was investigated, and it was shown the presence of clusters encoding NopE type III-secreted protein similar to the NopE1 and NopE2 of B. diazoefficiens USDA 110T. The putative NopE protein of LmjC strain is at present being characterized regarding its structure and function.

Ethnobotanic importance of plants used in pigeon-breeding in Eastern Spain

Background: The importance that birds of the Columbidae family have had throughout history is visible on the Mediterranean coast. Pigeon fancying is the art of breeding and training carrier pigeons and currently, several breeds exist. The sport of racing pigeons consists in covering a distance at maximum possible speed. However, pigeon breeding has another modality called “sport pigeon”, where several males follow a female. This study focusses on ethnobotanical knowledge of native and exotic plant species that are used for diet, breeding, stimulation, healing illnesses and staining the plumage of pigeons bred in captivity. Methods: Using semi-structured interviews, we gathered information about the different plant species traditionally used for pigeon-breeding in the region of Valencia. Background material on remedies for bird illnesses was gathered from folk botanical references, local books and journals. The plant species were collected in the study area, then identified in the laboratory using dichotomous keys and vouchered in the ABH (Herbarium of Alicante University). We used Excel ® 2003 to perform a simple statistical analysis of the data collected. Results: We collected 56 species of plants (and one variety) that included 29 botanical families. The total number of species was made up of 35 cultivated and 21 wild plants. The most common were Gramineae (14 species), Leguminosae (6 species), and Compositae (4 species). Conclusions: Pigeon breeding is an immensely popular activity in Eastern Spain, and ethnobiological knowledge about breeding pigeons and caring for them is considerable. The names and traditional uses of plants depend on their geographical location, vernacular names serve as an intangible heritage. Feeding, environmental features, and genetic makeup of individuals are relevant aspects in the maintenance of avian health.

Fish diversity and traditional fishing methods in semiarid irrigated system in the Bajo Vinalopó region, Southeastern Spain

The aim of this paper is to obtain a comprehensive picture of the importance of the fish fauna in the wetlands and coastal lagoons of the Bajo Vinalopó region (Alicante, South eastern Spain) and the ecological, historical and cultural value of the traditional knowledge on fishing maintained by local people. We have compiled data from different information sources: (1) the revision of historical archives, (2) personal interviews and collaborative research, and (3) ecological and water quality data. The results show that the area sustains important fish fauna diversity (17 species) and that local people have inherited a considerable traditional knowledge on fishing methods (11 modalities), on the maintenance and sound management of the water system and on the ecology and behaviour of fish. We conclude that a comprehensive consideration of all these ecological, historical and socio-cultural aspects related to fish and fishing shows clearly the value of this ecological and cultural heritage and provides a necessary base for a sustainable management of the area.

Ecological gradients and landscape structure affecting seasonal woodpigeon Columba palumbus densities in a coastal region (South-East Spain)

The aim of the present study is to identify and evaluate the relationship between Woodpigeon (Columba palumbus, Linnaeus, 1758) density and different environmental gradients (thermotype, ombrotype, continentality and latitudinal), land use and landscape structure, using geographic information systems and multivariate modelling. Transects (n = 396) were developed to estimate the density of Woodpigeon in the Marina Baja (Alicante, Spain) from 2006 to 2008. The highestdensity for Woodpigeon was in September-October (1.28birds/10ha) and the lowest inFebruary-March (0.34birds/10ha). Moreover, there were more Woodpigeons in areas with a mesomediterranean thermotypethan in thermomediterranean or supramediterranean ones. There was greater densityinthe intermediate zones compared to thecoast and interior. The natural or cultural landscape had the highest Woodpigeon density (1.53birds/10ha), with both denseand clear pine forest values standing out. Therefore, it is very important to conserve these traditional landscapes with adequate management strategies in order to maintain, resident and transient Woodpigeon populations. These natural areas are open places where the Woodpigeons find food and detect the presence ofpredators. Thus, this study will enable more precise knowledge of the ecological factors (habitat variables) that intervene in the distribution of Woodpigeon populations and their density.
