[ZG] Péninsule ibérique [Thèmes] Pyrénées Mots-clés : analyse multivariée  distribution diamétrique  mortalité Résumé : "A comparative study was carried out among stands of Pinus uncinata Ram. located, respectively, in La Massana (Andorra) and in the Catalonian Pyrenees, and give these sites an important role against snow avalanches. To check if there exist some differential attributes between Andorran and Catalonian sites, a dendrometric database was generated from sampling (Andorra) and from the information provided by the Third Forest National Inventory (Catalonian Pyrenees). As for their tendency towards uneven-aged stand structure, both geographical regions are quite similar. In fact, stand regeneration is not associated to other stocking variables, and stand stocking is not closely linked to the altitudinal gradient (which little affects mortality). However, Catalonian stands have shown less stocking and, in general, they offer worse characteristics for their protective role against avalanches compared with the Andorran stands."

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."
