Analysis of temporal and spatial variations of forest. A case of study in notheastern Armenia

The forest has a crucial ecological role and the continuous forest loss can cause colossal effects on the environment. As Armenia is one of the low forest covered countries in the world, this problem is more critical. Continuous forest disturbances mainly caused by illegal logging started from the early 1990s had a huge damage on the forest ecosystem by decreasing the forest productivity and making more areas vulnerable to erosion. Another aspect of the Armenian forest is the lack of continuous monitoring and absence of accurate estimation of the level of cuts in some years. In order to have insight about the forest and the disturbances in the long period of time we used Landsat TM/ETM + images. Google Earth Engine JavaScript API was used, which is an online tool enabling the access and analysis of a great amount of satellite imagery. To overcome the data availability problem caused by the gap in the Landsat series in 1988- 1998, extensive cloud cover in the study area and the missing scan lines, we used pixel based compositing for the temporal window of leaf on vegetation (June-late September). Subsequently, pixel based linear regression analyses were performed. Vegetation indices derived from the 10 biannual composites for the years 1984-2014 were used for trend analysis. In order to derive the disturbances only in forests, forest cover layer was aggregated and the original composites were masked. It has been found, that around 23% of forests were disturbed during the study period.

Penicillium glabrum cork colonising isolates – preliminary analysis of their genomic similari

Cork stopper manufacturing process includes an operation, known as stabilisation, by which humid cork slabs are extensively colonised by fungi. The effects of fungal growth on cork are yet to be completely understood and are considered to be involved in the so called “cork taint” of bottled wine. It is essential to identify environmental constraints which define the appearance of the colonising fungal species and to trace their origin to the forest and/or as residents in the manufacturing space. The present article correlates two sets of data, from consecutive years and the same season, of systematic biologic sampling of two manufacturing units, located in the North and South of Portugal. Chrysonilia sitophila dominance was identified, followed by a high diversity of Penicillium species. Penicillium glabrum, found in all samples, was the most frequent isolated species. P. glabrum intra-species variability was investigated using DNA fingerprinting techniques revealing highly discriminative polymorphic markers in the genome. Cluster analysis of P. glabrum data was discussed in relation to the geographical location of strains, and results suggest that P. glabrum arise from predominantly the manufacturing space, although cork resident fungi can also contrib

Incidência do cancro do estômago e do pulmão : um estudo espacio-temporal na região sul de Portugal Continental entre 2000-2008

RESUMO - Enquadramento/Objectivos: As doenças oncológicas constituem a segunda causa de morte em Portugal, e têm um profundo impacto psicossocial, não só pela sua elevada incidência e mortalidade mas também pelos enormes custos envolvidos na sua prevenção, tratamento e reabilitação. De acordo com estudos anteriores, existem disparidades geográficas na incidência da doença oncológica. É por isso indispensável caracterizar e analisar as diferentes distribuições espaciais no tempo e no espaço, para controlar a doença e promover a saúde, contribuindo ao mesmo tempo para uma melhor compreensão da etiologia da doença. Este projecto compreende 3 objectivos principais que são: a caracterização de distribuição espacio-temporal do cancro do pulmão e do cancro do estômago, separadamente e em conjunto, na região sul de Portugal Continental (abrangida pelo ROR-Sul) no espaço temporal de 2000 a 2008, procurando identificar potenciais áreas de risco no desenvolvimento destes tumores. Metodologia: Numa primeira fase realizou-se um estudo descritivo das taxas de incidência dos tumores aqui retratados por idades, por sexo, por ano e por distritos. Posteriormente com o objectivo de identificar a presença de áreas de elevada incidência, procedeu-se à análise de clustering espacio-temporal das taxas de incidência ao nível dos concelhos na região do estudo, em 2000-2008. Resultados: Os resultados da análise descritiva revelaram que ambos os tumores são mais incidentes nos homens do que nas mulheres e que estes são igualmente mais incidentes em pessoas com mais de 75 anos. A análise de clustering espacio temporal permitiu verificar a existência um padrão geográfico heterogéneo da incidência de ambos os tumores, da qual resultaram 3 clusters para o cancro do estômago e 2 clusters para o cancro do pulmão (p <0,001). Os clusters do estômago pertencem maioritariamente à região do Alentejo e os clusters do cancro do pulmão à região da grande Lisboa. Conclusões: Os resultados da análise de clustering demonstraram um padrão heterogéneo da distribuição da incidência dos dois cancros na região e período temporal do estudo. As zonas identificadas de elevado risco são diferentes para ambos o tumores. A região que apresenta maior risco para o desenvolvimento do cancro do estômago é o Alentejo e do pulmão é o distrito de Lisboa.
