Avaliação dos turdídeos caçados na Região Centro de Portugal : 1990-2005

Mestrado em Ecologia, Biodiversidade e Gestão de EcossistemasPortugal e Espanha constituem importantes locais de passagem e invernadapara muitas aves migratórias, com particular relevo para os turdídeos. Os turdídeos - tordo-comum (Turdus philomelos), tordo-ruivo, (Turdus iliacus), tordo-zornal (Turdus pilaris), tordeia (Turdus viscivorus) e melro (Turdus merula) - são aves que apresentam uma ampla distribuição geográfica na região do Paleárctico e utilizam oterritório Português essencialmente durante o período de invernada, com excepção da tordeia e do melro que sãonidificantes e ainda uma pequeníssimas população de tordo-comum que nidifica na Região Norte, ao longo da fronteira com Espanha. Estas espécies de tordos integram a lista de espécies cinegéticas Portuguesae como tal são passíveis de ser caçadas. Á excepção do melro, que há muitos anos não é caçado, todas as outras espéciesestão sujeitas a forte pressão cinegética, a qual tem vindo a aumentar ao longo dos últimos anos. Em Portugal e na ausência de um programa de monitorização destasespécies, os únicos dados existentes sobre as populações de tordos são os registos anuais dos exemplares abatidos nas zonas de caça. A recolha desta informação iniciou-se no ano de 1987, aquando da constituição das primeiraszonas de caça. Decorridos mais de vinte anos e existindo um grande númerode registos de tordos abatidos a nível nacional, efectuou-se a análise da informação obtida na Região Centro de Portugal no período de 1990 a 2005, correspondendo a dezasseis épocas venatórias. Pretendeu-se avaliar as tendências populacionais dos tordos ao longo do período considerado, adistribuição espacial destas populações de tordos, bem como a relação queexiste entre estas e a ocupação do solo na Região Centro. Os resultadosobtidos permitem concluir que a densidade média de tordos abatidos ao longo dos anos apresenta algumas flutuações mas as populações aparentam estar estáveis. Através da análise espacial da distribuição dos tordos abatidos foi possível apurar que existem dois eixos migratórios principais a nível da RegiãoCentro, os quais são separados pela Cordilheira Central, passando um a Noroeste e outro a Este desta. A relação encontrada entre a densidade média de tordos abatidos a ocupação do solo e permite-nos afirmar que a densidade está directamente relacionada com as espécies vegetais que constituem ocoberto vegetal, de tal forma que as maiores densidades de tordosocorrem nos locais onde existem espécies vegetais produtoras de frutos e bagas, designadamente nos olivais, pomares, e em áreas florestais e agrícolasintegradas em espaços naturais.Portugal and Spain are important regions for wintering and as migratory routes for many migratory birds, with particular focus to the thrushes. This group, represented in Portugal by song thrush (Turdus philomelos), redwing thrush (Turdus iliacus), fieldfare thrush (Turdus pilaris), mistle thrush (Turdus viscivorus) and blackbird (Turdus merula). They present a widegeographic distribution in Palearctic and use the Portuguese territory during the winterperiod, with exception of mistle thrush and the blackbird that breed in our country. These species of thrushes belong to the game species list in Portugal. The only exception are blackbirds, that are not hunted for many years, contrarily to all the others that experimented a strong hunting pressure duringthe last years. Due to the absence of a thrushes programme survey in Portugal, the only existing data on their populations are the annual hunting bags. The collection of this information began in 1987, when the first Portuguese hunting area was created. Twenty years latter an analysis of the data collected in the Central Region of Portugal was done for the period 1990-2005, corresponding to sixteen hunting seasons with the aim of evaluate the thrushes population trends along this period, their space distribution, and its relation with the soil cover and uses in Centre of Portugal. It was possible to verify that the mean density of hunted thrushes throughout the years presents some fluctuations butthe population seems to be stable. Through the space analysis of the distribution of the killed thrushes it was possible to select two main migratory routes existing in Centre of Portugal which are separate by the Central Mountain range (Estrela Mountain-Lousã Mountain). One is located inNorthwest of this mountain range and the other Southwest. The mean hunted thrushes densities are directly related with the vegetal cover of the region. The highest densities of thrushes occurs in the areas where fruit and berries trees and scrubs are dominant, with special reference to olive trees, orchardsand for areas where the forest patches are close the agriculture fields

Nature conservation, land use planning and exploitation of ornamental stones

ABSTRACT: Cabeça Veada is the name of a relatively small exploitation cluster for ornamental limestones occupying an area of 98 ha in the Portuguese Natural Park of Serra de Aire e Candeeiros, which is also a Natura 2000 Network protected area. Supported by comprehensive geological, mining and environmental studies, a specific methodology was developed in order to address the compatibility between the long term sustainability of this industry with the preservation of existing protected natural values. The obtained land use map should allow the Cabeça Veada mineral resources to be adequately included in the municipal land use planning process.N/

A telehealth system for Parkinson's disease remote monitoring. The PERFORM approach

This paper summarizes the experience and the lessons learned from the European project PERFORM (A sophisticated multi-parametric system FOR the continuous effective assessment and monitoring of motor status in Parkinson s disease and other neurodegenerative diseases). PERFORM is aimed to provide a telehealth system for the remote monitoring of Parkinson s disease patients (PD) at their homes. This paper explains the global experience with PERFORM. It summarizes the technical performance of the system and the feedback received from the patients in terms of usability and wearability

Iron-enriched diet contributes to early onset of osteoporotic phenotype in a mouse model of hereditary hemochromatosis

Osteoporosis is associated with chronic iron overload secondary to hereditary hemochromatosis (HH), but the causative mechanisms are incompletely understood. The main objective of this study was to investigate the role of dietary iron on osteoporosis, using as biological model the Hfe-KO mice, which have a systemic iron overload. We showed that these mice show an increased susceptibility for developing a bone loss phenotype compared to WT mice, which can be exacerbated by an iron rich diet. The dietary iron overload caused an increase in inflammation and iron incorporation within the trabecular bone in both WT and Hfe-KO mice. However, the osteoporotic phenotype was only evident in Hfe-KO mice fed the iron-enriched diet. This appeared to result from an imbalance between bone formation and bone resorption driven by iron toxicity associated to Hfe-KO and confirmed by a decrease in bone microarchitecture parameters (identified by micro-CT) and osteoblast number. These findings were supported by the observed downregulation of bone metabolism markers and upregulation of ferritin heavy polypeptide 1 (Fth1) and transferrin receptor-1 (Tfrc), which are associated with iron toxicity and bone loss phenotype. In WT mice the iron rich diet was not enough to promote a bone loss phenotype, essentially due to the concomitant depression of bone resorption observed in those animals. In conclusion the dietary challenge influences the development of osteoporosis in the HH mice model thus suggesting that the iron content in the diet may influence the osteoporotic phenotype in systemic iron overload conditions.National Funds through Foundation for Science and Technology (FCT) Norte-01-0145-FEDER-000012 Portuguese Foundation for Science and Technology (FCT) SFRH/BD/77056/2011 European Regional Development Fund (FEDER) Norte-01-0145-FEDER-000012info:eu-repo/semantics/publishedVersio

User centered design to incorporate predictive models for type 2 Diabetes screening and management into professional decision support tools: preliminary results

Type 2 Diabetes screening and risk stratification tools could benefit from the incorporation of predictive systems based on computer modelling. The adoption of User Centered Design techniques is fundamental in order to integrate these systems in an effective and successful way. The work presented in this paper describe the methodologies used in the context of a multidisciplinary research project and provides an overview of the preliminary results. Keywords?
