Implementation of IUCN criteria for the definition of the Red List of Ecosystems in Italy, Plant Biosystems.
The present work is aimed at presenting the data, methods and criteria that are being used for the assessment of ecosystem collapse risk in Italy.
The order Quercetalia virgilianae: a new proposal for the classification of semi-deciduous forests in the Mediterranean and sub-Mediterranean area.
The semi-deciduous oaks belonging to Quercus pubescens s.l. group (Q. congesta C. Presl, Q. virgiliana (Ten.) Ten., Q. dalechampii Ten., Q. amplifolia Guss. and Q. leptobalanus Guss.) are widespread in the Italian Peninsula, Sicily, Sardinia and along the southern coasts of the Balkan peninsula and more generally in the whole Mediterranean area, especially in the transition zone between the temperate and Mediterranean macrobioclimate identified by the sub-mediterranean variant (Brullo et al., 1999). These forests are currently expanding rapidly because of the decreased anthropic exploitation. The syntaxonomic classification of these forest typologies is quite critical, because their florist…
The RIBES strategy for ex situ conservation: conventional and modern techniques for seed conservation
The Italian seed bank network (RIBES) aims to improve the quality and safety of the germplasm reserves of native plant species in Italy to ensure the long-term conservation of endangered and/or endemic flora. The strategy includes traditional methods to secure seed conservation. A comprehensive priority list for seed collection is being defined, it was prepared by crossing data of various checklists (red lists, endemics) and will soon be cross-referenced with an updated list of accessions of the whole network. A safety-backup program of duplicates will quickly be implemented to secure the conservation of the most threatened species in at least two seed banks of the network. On the other han…
