Effects of ozone on the foliar histology of the mastic plant (Pistacia lentiscus L.)
2004
[EN] An open-top chamber study was conducted to investigate the tissue and cellular-level foliar effects of ozone (O-3) on a Mediterranean evergreen species, the mastic plant (Pistacia lentiscus L.). Plants were exposed at three different O-3 levels, and leaf samples were collected periodically from the beginning of the exposure. Although no visible foliar injury was evident, alterations of the plastids and vacuoles in the mesophyll were observed. Senescence processes were accelerated with an anomalous stacking of tannin vacuoles, and a reduction in the size and number of the chloroplasts. Overall, most of the modifications induced by O-3 were consistent with previously reported observation…
Distribution and ecological role of selected shrubby species in the Mediterranean basin
2019
In many natural and semi-natural habitats trees and shrubs represent two major growth forms (1). In particular shrublands, which can be considered a mixture of several sclerophyllous shrubs and tree species, represent a Mediterranean type of vegetation rarely found in other ecosystems. The distribution of shrubs in an ecosystem is connected to complex ecological processes. Indeed, shrubs provide substrate, food and shelter for organisms, play an important role in the nutrient cycle providing organic matter input to soils and they protect watersheds from erosion. Moreover shrubs are very important for many associated species such as mammals, birds, invertebrates, other plants (that favour th…
