Terrestrial orchids are experiencing a great extinction risk because of a multiplicity of threatening processes. Thus, during the last ten years, Tuscia Germplasm Bank and Botanical Garden “Angelo Rambelli” of Viterbo, in collaboration with the local section of G.I.R.O.S. association (Italian Group for Research on Wild Orchids), have been carrying...

This paper aims to illustrate the activities and projects related to wild orchids conservation carried out through collaboration among Tuscia Germplasm Bank, Botanical Garden (Tuscia University, Italy) and the local Section of G.I.R.O.S. association.

The Authors report the finding of the northernmost population of the natural hybrid Ophrys ×grottagliensis (Ophrys bertolonii subsp. bertolonii x Ophrys garganica) in Tuscia University Botanic Gardens, Viterbo (Latium, central Italy). From preliminary morphological studies, the hybrid shows some characters of the parental species and others interme...

Dal 2003 l’Orto Botanico della Tuscia, in sintonia con quanto riportato nel Piano d’Azione per i Giardini Botanici nell’Unione Europea, ha intrapreso attività di conservazione ex situ di orchidee spontanee italiane attraverso la raccolta di esemplari in natura e l’allestimento di una collezione che accoglie oggi circa 30 specie di orchidee, anche...

Biomass productivity and soil microbial responses to long-term CO2 enrichment have been investigated in a Mediterranean natural forest ecosystem. Several biochemical parameters have been measured on soil samples taken from six open top chambers (OTCs), enclosing clumps of natural Mediterranean woody vegetation including: Quercus ilex L., Phillyrea...

La Banca del Germoplasma dell'Orto Botanico di Viterbo in collaborazione con l'Erbario della Tuscia ha intrapreso un progetto di conservazione ex situ di Pteridofite minacciate della flora italiana, che prevede la raccolta di spore sia da exsiccata sia da individui provenienti da popolazioni naturali per la riproduzione in vitro e la coltivazione a...

The colonisation of microfungi in litter bags with Phillyrea angustifolia L. leaf litter was followed for two years; the succession of microfungal communities was analysed. Two main groups of fungi were identified, whose presence is correlated with the successive decomposition stages of the substrate and with seasonal variations.

The natural biodiversity of Beltrania rhombica Penzig on litter of Pistaria lentiscus L. was studied by statistical methods in four coastal stations with Mediterranean maquis. Sixty‐four colonies were examined and compared, leading to the identification of 14 statistically homogeneous groups. The differences in morphology and dimensions observed in...
