Hunting management in relation to profitability aims: red-legged partridge hunting in central Spain
22 páginas, 3 tablas, 2 figuras.Game management is widely implemented in Spain, affecting more than 70 % of land cover. Management intensity may be linked to the financial aims of hunting estates, but no study of these aspects has been developed in Spain, where commercial hunting is common. Through interviews with game managers and field surveys, we quantified physical and economic traits, management techniques and hunting methods in a sample of 59 small game hunting estates located in south-central Spain (where Red-legged partridge hunting has the highest socio-economic importance in the country). We compared non-commercial estates (aimed for leisure, managed mainly by local hunting societies) and commercial estates (aimed at financial benefit); among the latter, we also assessed “intensive” estates (a special category of commercial estates licensed to release farm-reared partridges without temporal or numerical limits throughout the hunting season). Commercial estates had more intensive management, including more and larger partridge releases, higher density of supplementary feeders and more intensive predator control. Thus, any positive or negative effects on biodiversity of these management techniques would be higher in commercial than in non-commercial estates. Commercial estates also retained more natural vegetation, which may help to enhance the landscape and biodiversity value of farmland in central Spain. On the other hand, differences in management and hunting styles were most marked between intensive and other type of estates (both commercial and non-commercial); this indicates that intensive estates are qualitatively different from other small game estates, both ecologically (hunting based on releases and driven shooting) and economically (higher inputs and outputs). It would be desirable to find ways to quantify the environmental or social costs and benefits of different management techniques, and integrate them in the economics of hunting estates.This work was supported by the European Commission under the 7th Framework Programme for Research and Technological Development through project HUNT (212160, FP7-ENV-2007-1), Ministerio de Ciencia y Tecnología (CGL2008-04282/BOS) and the Consejería de Agricultura of Junta de Comunidades de Castilla-La Mancha (JCCM).

Mapping poverty at the local level in Europe: A consistent spatial disaggregation of the AROPE indicator for France, Spain, Portugal and the United Kingdom
In the EU, territorial inequalities in terms of income and poverty have been broadly analysed at the national and regional levels. However, mainly due to the lack of reliable data, very little attention has been paid to territorial inequalities within European regions, namely, at a more local level, such as in metropolitan areas, cities or neighbourhoods. This paper proposes a methodology to disaggregate official regional poverty figures into poverty indicators for smaller spatial units, mainly local administrative units. For each country, poverty figures at the regional level from household surveys are combined with microcensus data that contain details on the local entities of residence to disaggregate the regional poverty indicator. In contrast to previous methodologies, our proposed technique guarantees consistency between the local poverty estimates and the regional poverty figures through a second step that adjusts the initial estimates based on generalized cross entropy. The procedure is applied for four European countries: France, Spain, the United Kingdom and Portugal. The resulting local estimates provide an intraregional map of poverty and some insights into the particular behaviour of the capital regions and the disparities between city centres and their surrounding areas.En la UE, las desigualdades territoriales en cuanto a ingresos y pobreza se han analizado ampliamente a nivel nacional y regional. Sin embargo, debido principalmente a la falta de datos fiables, se ha prestado muy poca atención a las desigualdades territoriales dentro de las regiones europeas a un nivel más local, como pueden ser las zonas metropolitanas, las ciudades o los barrios. En el presente artículo se propone una metodología para desglosar las cifras regionales oficiales de pobreza en indicadores de pobreza para unidades espaciales más pequeñas, principalmente unidades administrativas locales. Para cada país, se combinan las cifras de pobreza a nivel regional procedentes de las encuestas de hogares con datos de microcensos que contienen detalles sobre las entidades locales de residencia para desglosar el indicador de pobreza regional. A diferencia de las metodologías anteriores, la técnica que se propone aquí garantiza la coherencia entre las estimaciones de pobreza locales y las cifras de pobreza regionales mediante un segundo paso que ajusta las estimaciones iniciales basadas en la entropía cruzada generalizada. El procedimiento se aplica en cuatro países europeos: Francia, España, el Reino Unido y Portugal. Las estimaciones locales resultantes proporcionan un mapa intrarregional de la pobreza y algunas percepciones del comportamiento particular de las regiones que albergan la capital y las disparidades entre los centros de las ciudades y sus zonas circundantes
The role of economic and social factors driving predator control in central Spain
14 páginas, 3 figuras, 3 tablas.One of the most important human-wildlife conflicts in the world is that where predators are involved. Predators
may compete with us for the same resources, such as game species. As a consequence, predators have been frequently controlled
by game managers, which has negatively affected many predator populations worldwide. The understanding of human-wildlife
conflicts requires a multidisplicinary framework that is rarely considered. We aim to evaluate the attitudes and behavior of game
managers with regard to predator management in central Spain, as well as to explore factors that lead to these attitudes and
behavior. Data were gathered through face to face interviews with game managers from 59 small-game hunting estates within
central Spain. Predator control was employed in 90% of the estates, but control intensity was very variable among estates.
Economic interests and perceptions about predators apparently influenced variation in control intensity. The main methods
employed were cage-traps and shooting, but some illegal practices (e.g., leg-hold traps or snares without stopping devices) were
also admittedly used for carnivores. Most managers considered that efficacy of legal methods for control of foxes (Vulpes vulpes)
was very limited. Overall, nonselective methods, such as some types of snares, were more frequently employed in commercial
than in noncommercial estates. Most managers believed that predators had an important effect on prey, and therefore that not
doing it would lead to smaller hunting bags. Only managers from commercial hunting estates used stronger discourses such as
that hunting would be impossible without carrying out predator control, which suggests that their tolerance for predators was
lower than that of managers whose main motivation was not economic. Most managers considered that predator control was
effective to reduce the number of predators, but only in the short term. Therefore, they highlighted the need of maintaining
predator control every year. Our results highlight the important role that both social and economic factors (even stronger than
ecological factors) play driving predator control, and therefore the need of incorporating these factors when making decisions
to mitigate the human-predator conflict.This work was supported by the European Commission under

The TLC: A Novel Auditory Nucleus of the Mammalian Brain
[EN]We have identified a novel nucleus of the mammalian brain and termed it the tectal longitudinal column (TLC). Basic histologic stains, tract-tracing techniques and three-dimensional reconstructions reveal that the rat TLC is a narrow, elongated structure spanning themidbrain tectum longitudinally. This paired nucleus is located close to the midline, immediately dorsal to the periaqueductal gray matter.It occupies what has traditionally been considered the most medial region of the deep superior colliculus and the most medial region of the inferior colliculus. The TLC differs from the neighboring nuclei of the superior and inferior colliculi and the periaqueductal gray by its distinct connections and cytoarchitecture. Extracellular electrophysiological recordings show that TLC neurons respond to auditory stimuli with physiologic properties that differ from those of neurons in the inferior or superior colliculi. We have identified the TLC in rodents, lagomorphs, carnivores, nonhuman primates, and humans, which indicates that the nucleus is conserved across mammals. The discovery of the TLC reveals an unexpected level of longitudinal organization in the mammalian tectum and raises questions as to the participation of this mesencephalic region in essential, yet completely unexplored, aspects of multisensory and/or sensorimotorintegration.[ES]Hemos identificado un nuevo núcleo del cerebro de los mamíferos y lo hemos denominado columna longitudinal tectal (CLT; TLC por sus siglas en inglés). Mediante tinciones histológicas básicas, técnicas de trazado de vías nerviosas y reconstrucciones tridimensionales hemos observado que la CLT es una estructura larga y estrecha que recorre longitudinalmente el techo mesencefálico. Este núcleo par se encuentra próximo a la línea media, inmediatamente dorsal con respecto a la sustancia gris periacueductal. Ocupa un territorio considerado tradicionalmente como la región más medial de las capas profundas del colículo superior y la región más medial del colículo inferior. La CLT difiere de los núcleos que la rodean (colícuo superior, colículo inferior y sustancia gris periacueductal) por sus conexiones y su citoarquitectura. Los registros electrofisiológicos extracelulares muestran que las neuronas de la CLT responden a los estímulos auditivos y que sus propiedades de respuesta son distintas de las de las neuronas de los colículos superior e inferior. Hemos identificado la TLC en el cerebro de roedores, lagomorfos, carnívoros, primates no humanos y seres humanos, lo que indica que el núcleo está filogenéticamente conservado en una gran variedad de mamíferos. El descubrimiento de la CLT revela un insospechado nivel de organización longitudinal en el techo mesencefálico de los mamíferos y suscita preguntas sobre la participación de esta región mesencefálica en aspectos esenciales de la integración multisensorial y/o sensorimotora que hasta ahora no han sido estudiados
Fracturas epifisiolisis graves de la extremidad proximal del radio: resultado tras tratamiento quirúrgico
La fractura-epifisiolisis del cuello radial es una lesión grave que puede
originar alteracione s en e l crecimiento epifisario. Presentamo s una seri e de 22 casos
revisados con una antigüedad mínima de dos años. Fueron intervenidos 14 pacientes,
de los que 10 estaban incluidos en el grupo III o en lesione s de Jeffery. Once enfermos
fueron tratado s con cirugí a abierta. Cuando l a intervenció n consisti ó en reducció n
abierta y osteosíntesis, los resultados clínicos fueron buenos en el 50%, pero cuando só-
lo se practicó reducción cruenta sin asociar sistema estabilizador metálico, éstos llegaron
al 100%. En cinco de los ocho paciente s del primer grupo se presentaron calcificacione
s articulares y en dos, epifisiodesis. En el segundo grupo no aparecieron ninguna
de éstas alteraciones. Creemos que en los casos de fracturas epifisiolisis del cuello radial
en niños con gran desplazamiento, el tratamiento ideal es la cuidadosa reducción
cruenta evitando fijación con aguja.The fracture epiphysiolysis of radial neck is a grave lesion which may

Desarrollo de un sistema de Gestión Frutihortícola
La tendencia actual hacia la globalización en todas las áreas de negocios, de los que no escapan los agropecuarios, ha significado un aumento de la competencia, tanto en intensidad como diversidad. En particular, el productor frutihortícola debe disponer de elementos que le permitan comprender los mercados como también contar con metodologías y herramientas con las cuales identificar debilidades y fortalezas de sus sistemas productivos, ir adaptándose a un medio altamente dinámico y dar sentido estratégico a la dirección de la empresa. Se propuso desarrollar un aplicativo que, sin pretender ser un sistema de contabilidad de costos, utiliza a ésta como principal fuente del conocimiento. Es así como se estructuró el sistema de gestión orientado, cuya interactividad surge a partir de las actividades que desarrolla habitualmente el productor en su establecimiento. A partir de allí se disparan una serie de procesos estructurados que concluyen en el registro de la actividad como en un sistema de contabilidad de costos. Se desarrolló un sistema informático basado en tecnología Microsoft Office Access para Windows como gestor de base de datos y entorno de desarrollo Visual Basic for Applications. El sistema aún no se está utilizando a campo, pero se cuenta con grupos de productores dispuestos a probarlo.Sociedad Argentina de Informática e Investigación Operativ
