Floresta natural dos Açores

O efeito da insularidade reflecte-se no número limitado de espécies arbóreas naturais dos Açores. As mais comuns são a Morella faya (Faia-da-terra), Picconia azorica (Pau-branco), Laurus azorica (Louro), Juniperus brevifolia (Cedro-do-mato), Ilex perado subsp. azorica (Azevinho), Erica azorica (Urze) e Frangula azorica (Sanguinho). Pelo contrário, Prunus azorica (Ginjeira-brava) é actualmente muito rara e Taxus bacatta (Teixo) encontra-se à beira da extinção. Dependendo das condições ambientais, particularmente de temperatura, pluviosidade e exposição ao vento, encontramos diferentes espécies a dominar a copa da floresta. […].

Early patterns of recovery from disturbance in intertidal algal assemblages: consistency across regions within a marine province

The importance of disturbance and the subsequent rate and pattern of recovery has been long recognised as an important driver of community structure. Community recovery is affected by processes operating at local and regional scales yet the examination of community level responses to a standardised disturbance at regional scales (i.e. among regions under different environmental conditions) has seldom been attempted. Here, we mechanically disturbed rocky intertidal lower shore algal dominated assemblages at three locations within each of three different regions within the Lusitanian biogeographical province (Azores, northern Portugal and the Canary Islands). All organisms were cleared from experimental plots and succession followed over a period of 12 months at which time we formally compared the assemblage structure to that of unmanipulated controls. Early patterns of recovery of disturbed communities varied among regions and was positively influenced by temperature, but not by regional species richness. Different components of the assemblage responded differently to disturbance. Regional differences in the relative abundance and identity of species had a key influence on the overall assemblage recovery. This study highlights how regional-scales differences in environmental conditions and species pool are important determinants of recovery of disturbed communities.
