Chemical-physical agents and biodeteriogens in the alteration of limestones use...
Columbu, Stefano; Sitzia, Fabio; Bachetta, Gianluigi; Podda, Lina; Calvia, Giacomo; Coroneo, Valentina; Pirinu, Andrea; Josè, Mirao; Moita, PatriciaThe alteration of rocks is usually due to the chemical-physical processes that are initially established on the outer surface of the stone and gradually proceed towards the inner matrix. The chemical alteration generated by the interaction with atmospheric agents (weathering) involves the transformation of the mineral phases constituting the rock that are less stable in the current climatic conditions. That oft...
Seed Germination Ecophysiology of Acacia dealbata Link and Acacia mearnsii De W...
Dessì, Ludovica; Podda, Lina; Brundu, Giuseppe; Lozano, Vanessa; Carrouée, Antoine; Marchante, Elizabete; Marchante, Hélia; Petit, YohanAcacia dealbata and A. mearnsii are two invasive species found in coastal, mountain, and riparian Mediterranean habitats. Seed biology and germination traits are important drivers of the competitive performance of plants and may significantly contribute to biological invasions. The seeds of Acacia s.l. have physical dormancy due to an impermeable epidermal layer. The aim of this study was to assess the germinat...
