Influência da gestão do habitat na distribuição e abundância do coelho-bravo no Sítio Natura 2000 Monchique

O coelho-bravo, devido à sua importância ecológica e económica, tem sido alvo de diversos planos de gestão e vários esforços têm sido empreendidos no sentido de contrariar o decréscimo das suas populações. Este estudo foi realizado em três zonas de caça do Sítio Monchique e o principal objectivo é determinar se as medidas de gestão implementadas influenciam a distribuição e abundância da espécie na área de estudo. A abundância relativa foi interpolada com o método "Inverso do Peso da Distância" {IDW), e as relações entre presença de coelho e os descritores ambientais foram analisadas através de Modelos Lineares Generalizados (GLM). Os resultados da modelação estatística mostraram que as medidas de melhoria de habitat parecem ter sido determinantes para um aumento da área de distribuição do coelho-bravo nos locais intervencionados. São propostas novas medidas de gestão, cujo objectivo será promover a continuação do aumento da ocorrência e abundância da espécie neste local. /ABSTRACT: The wild rabbit, due to its ecological and economical role, has been the target of several management plans and considerable efforts have been made to enhance its populations. This study was held in three game estates located inside Monchique Natura 2000. Site and aims to determine if the habitat management actions implemented in the study area influence rabbit distribution and abundance. The relative abundance was interpolated to all study area with lnverse Distance Weight method {IDW} and the relationships between rabbit presence and the environmental descriptors were evaluated with Generalized Linear Models (GLM). The results of the statistical modelling showed that the management actions seem to have contributed significantly to an enhancement on the rabbit occurrence in the studied game estates. Several new management actions are proposed with the aim to continue to increase rabbit occurrence and abundance in this site.

Reutilização de imóveis de interesse patrimonial, voltados para a ahabitação: um estudo de caso na Ribeira-Natal/RN

This work analyzes the reutilization of real estate of patrimonial interest, come back toward habitation. One understands as real estate of patrimonial interest the old ones that present relevant architectural typologies that must be preserved; some buildings that represent characteristic architectural styles of a determined period; some valued real estates for the history of the city (historical, memory and image signification that has of certain places) and buildings with exceptional artistic elements. In short, real estate of patrimonial interest. The place or site to be studied will be the neighborhood of the Ribeira, because is an area that protects a bigger interest for the historic patrimony of the city. The habitation use was thought as a booster element of revitalization processes of degradable historic site, contributing to the preservation of artistic, architectural and historic patrimony, and thus to stimulate the accomplishment of the re-qualification of the neighborhood of the Ribeira. It is intended with the present study to examine alternatives to make possible habitation re (uses) in the historical quarter of the Ribeira in old constructions of patrimonial value

Evidence of shared bovine viral diarrhea infections between red deer and extensively raised cattle in south-central Spain

Bovine viral diarrhea virus (BVDV) is a pestivirus that affects cattle production worldwide and that can infect other ungulates such as cervids and even wild boar (Sus scrofa). It is believed that domestic livestock can become infected through contact with wild animals, though it is known that infection can spread among wild animals in the absence of contact with livestock. Little is known about the sharing of BVDV infection between wild and domestic animals in the same habitat, which is important for designing eradication campaigns and preventing outbreaks, especially on hunting estates with high animal densities.

Papel de la comunidad internacional en la resocialización de niños soldados desvinculados del ejército de resistencia del señor en Uganda (2002-2013)

El objetivo de esta investigación diagnóstica es evaluar las acciones de la Comunidad Internacional en materia de resocialización de niños soldados desvinculados del Ejército de Resistencia del Señor (ERS) en Uganda durante el periodo de 2002 a 2013. Para ello, se hace un análisis de las causas de la existencia de niños soldados, donde se tiene en cuenta la evolución del concepto de la infancia y las particularidades que éste representa en el contexto africano. Así mismo, son analizados los alcances y limitaciones del modelo de asistencia humanitaria para la protección de la niñez enfatizando en los procesos de resocialización brindados a los niños desvinculados del ERS. Esto con el fin de evidenciar las limitaciones de la actuación de la Comunidad Internacional, y brindar una serie de recomendaciones para la implementación de programas de resocialización enfocados en la infancia.

Distribution modelling of wild rabbit hunting yields in its original area (S Iberian Peninsula)

In this work we used the information of the Annual Hunting Reports (AHRs) to obtain a high-resolution model of the potential favourableness for wild rabbit harvesting in Andalusia (southern Spain), using environmental and land-use variables as predictors. We analysed 32,134 AHRs from the period 1993/2001 reported by 6049 game estates to estimate the average hunting yields of wild rabbit in each Andalusian municipality (n5771). We modelled the favourableness for obtaining good hunting yields using stepwise logistic regression on a set of climatic, orographical, land use, and vegetation variables. The favourability equation was used to create a downscaled image representing the favourableness of obtaining good hunting yields for the wild rabbit in 161 km squares in Andalusia, using the Idrisi Image Calculator. The variables that affected hunting yields of wild rabbit were altitude, dry wood crops (mainly olive groves, almond groves, and vineyards), temperature, pasture, slope, and annual number of frost days. The 161 km squares with high favourableness values are scattered throughout the territory, which seems to be caused mainly by the effect of vegetation. Finally, we obtained quality categories for the territory by combining the probability values given by logistic regression with those of the environmental favourability function.

Geographical and environmental correlates of big and small game in Andalusia (southern Spain)

In Andalusia, southern Spain, each game estate applies its own rules and presents its results in annual hunting reports, which have been mandatory for Spanish game estates since 1989. We used the information about hunting yields, included in 32134 annual hunting reports produced during the period 1993/94 to 2001/02 by 6049 game estates, to determine the current distribution of hunting yields of big and small game species in Andalusia. Using generalised linear models and a geographic information system, we determined the most favourable municipalities to big and small game, respectively, and delimited potential areas to attain good hunting yields for big and small game at a 1-km2 resolution. Municipalities and areas favourable to big game are mainly located in the Sierra Morena and the westernmost fringe of the Betic Range, while those favourable to small game occupy the upper Guadalquivir River valley. There is a clear segregation between big and small game species according to the physiography and land uses of the territory. Big game species are typical of Mediterranean woodland areas, while the most emblematic small game species prefer agricultural areas. Our results provide a territorial ordination of hunting yields in southern Spain and have several potential applications in strategic planning for hunting activities and biodiversity conservation in Andalusia that can be extrapolated to other regions.

Land use and environmental factors affecting red-legged partridge (Alectoris rufa) hunting yields in southern Spain

The red-legged partridge is a small game species widely hunted in southern Spain. Its commercial use has important socioeconomic effects in rural areas where other agrarian uses are of marginal importance. The aims of the present work were to identify areas in Andalusia (southern Spain) where game yields for the red-legged partridge reach high values and to establish the environmental and land use factors that determine them. We analysed 32,134 annual hunting reports (HRs) produced by 6,049 game estates during the hunting seasons 1993/1994 to 2001/2002 to estimate the average hunting yields of red-legged partridge in each Andalusian municipality (n=771). We modelled the favourability for obtaining good hunting yields using stepwise logistic regression on a set of climatic, topographical, land use and vegetation variables that were available as digital coverages or tabular data applied to municipalities. Good hunting yields occur mainly in plain areas located in the Guadalquivir valley, at the bottom of Betic Range and in the Betic depressions. Favourable areas are related to highly mechanised, lowelevation areas mainly dedicated to intensive dry crops. The most favourable areas predicted by our model are mainly located in the Guadalquivir valley.
