Growth and Photosynthetic Responses of Scaevola sericea, A Hawaiian Coastal Shrub, to Substrate Salinity and Salt Spray

Morphological and physio-biochemical characterization ofBrassica junceaL. Czern. & Coss. genotypes under salt stress

“…Salinity tolerance is related to the maintenance of P N and g s (Lakshmi et al 1996;Khan et al 2007) and to elevated chlorophyll concentration (Winicov and Seemann 1990;Salama et al 1994). The magnitude of reduction in P N under salt stress as compared to control might be due to reduction in chloroplast stromal volume and generation of reactive oxygen species (Price and Hendry 1991) and to the closure of stomata caused by excessive accumulation of Na ' ion in guard cells, reduces the availability of internal CO 2 (Thiel and Blatt 1990;Nicolas et al 1993;Goldstein et al 1996;Huang et al 2006). Reddy and Vora (1986) summarized the degradation of chlorophyll molecules by the activity of chlorophyllase, under stress, the main reason for low Chl content.…”

Diversity of maritime juniper woodlands

“…Juniper woodlands on dune systems have a lower diversity of woody species which appears to be due to physical environmental factors such as salt spray, sand mobility, relatively infertile soils, and lower water availability. As characteristic communities of coastal dunes (Crawford, 1989;Goldstein et al, 1996), juniper woodlands are structurally open communities, with only a few woody species. There is a moderate sand mobility and the vegetation is composed by Ammophila arenaria, H. picardii, Armeria pungens and C. album among others.…”

“…Under such adverse environmental conditions, plant cover and species diversity tend to be low (Goldstein et al, 1996). On the other hand, the diversity of ''natural'' Mediterranean ecosystems should be affected by past human disturbances and their recent functioning (Van der Maarel, 1988;Montalvo et al, 1991).…”

Variation in the distribution of supralittoral vegetation around an atoll cay: Desroches (Amirante Islands, Seychelles)

“…Indeed it effectively forms a continuous band around the perimeter of the island, as it does naturally at several other Indo-Pacific cays (Wiens, 1962;Stoddart & Fosberg, 1991;Goldstein et al, 1996) and, un-naturally, outside the region where it is sometimes behaves as an invasive species, e.g. in Florida, USA (http:// plants.ifas.ufl.edu.scaser.html) and in the British Virgin Isles (http://www.seaturtle.org/ mtrg/projects/anegada/).…”
