Response of West Coast Beach Taxa to Salt Spray, Seawater Inundation, and Soil Salinity / Michael G. Barbour in Bulletin of the Torrey Botanical Club, vol. 104, n°1 (Année 1977)

Public [article]  inBulletin of the Torrey Botanical Club > vol. 104, n°1 (Année 1977) . - pp. 29-34 Titre : Response of West Coast Beach Taxa to Salt Spray, Seawater Inundation, and Soil Salinity Auteurs : Michael G. Barbour, Auteur ; Theodore De Jong, Auteur Année de publication : 1977 Article en page(s) : pp. 29-34 Langues : Anglais (eng) Catégories : [ZG] États-Unis [Thèmes] Morphologie végétale [Thèmes] Végétation Mots-clés : indice de tolérance  pulvérisation de sel  biomasse  mortalité Résumé : "Twelve taxa, characteristic of beach vegetation along the Pacific Coast of the United States, were grown from seed and subjected to realistic levels of salt spray (50 mg dm-2 day-1) and seawater inundation (residual soil salinity of 3,328 ppm). Mortality, morphology, and biomass were measured and combined in a tolerance index. For most taxa, this tolerance index correlated well with zonation position in the field (average plant position from tide line inland to foredune; r > 0.85). Three or four taxa behaved anomalously, exhibiting either much more or much less tolerance than expected from their zonation position, and we conclude that a single-factor approach is too naive to account for the distribution of all beach taxa."

The Vegetation of Exposed Sea Cliffs at South Stack, Anglessey, II. Experimental Studies / F. B. Goldsmith in Journal of Ecology, vol. 61, n°3 (Année 1973)

Public [article]  inJournal of Ecology > vol. 61, n°3 (Année 1973) . - pp. 819-829 Titre : The Vegetation of Exposed Sea Cliffs at South Stack, Anglessey, II. Experimental Studies Auteurs : F. B. Goldsmith, Auteur Année de publication : 1973 Article en page(s) : pp. 819-829 Langues : Anglais (eng) Catégories : [habitats/milieux] 18 - Côtes rocheuses et falaises maritimes [Thèmes] Ecologie [Thèmes] Végétation Mots-clés : pulvérisation de sel  communauté végétale  embrun salin Résumé : "The detailed investigation of a small area of cliff near South Stack, Anglesey, involved the collection of salt spray and a study of the temporal and spatial pattern of its deposition. Deposition was positively correlated with strong westerly winds, especially those over 30 knots. The amount of salt deposited depended primarily on height or distance from the sea and secondarily on local topographic features providing shelter or increasing exposure. Vegetational differences over the area intensively studied were considered to be due to the pattern of salt deposition and to differential rates of evaporation. The relationship between competition and salinity for maritime and inland species was investigated by selecting two species and growing them together in various proportions in a `de Wit' replacement series. Armeria maritima, the maritime species, had the competitive advantage under saline conditions but Festuca rubra, the inland one, had the advantage under non-saline conditions. Both species, however, produced the same yield when grown alone under both treatments. It is concluded that maritime cliff species have no salt requirement but, because they are slow-growing and semi-prostrate, they require an environment of low competitive intensity. Competition from inland species is reduced on exposed sea cliffs by high levels of soil salinity and foliar salt damage due to the incidence of salt spray during gales."
