Fungal communities in Mediterranean and Submediterranean woodlands
No full textA summary of data based on several mycocoenological studies, carried out in a belt extending from the Tyrrhenian coast to the foot of the C Apennines, is presented. The studies, concerning macromycetes, have been carried out in mediterranean and submediterranean communities; juniper scrubs on sandy dunes and evergreen oak woods of the Maremma coast; evergreen oakwoods, heathlands, and chestnut coppices of the hills; chestnut coppices and fir woods of submontane areas. Association between c700 fungal species, collected in 5.5 ha, and the seven phytocoenoses are analysed. Species diversity is noteworthy: 14.4% are species widely distributed in the phytocoenoses and 54.9% are associated with only one type of vegetation community

No full textIn the last 20 years, the scientific community has shown increasing interest in questions related to biodiversity. Knowledge of biodiversity is a prerequisite for mapping the distribution of species and for the conservation of the organisms populating ecosystems. Here we report the results of mycocoenological research in various types of forest ecosystems (evergreen oak woods of the hill and coastal belts, hill and montane chestnut woods, natural and artificial fir woods, acidophilous and basophilous deciduous oak woods) in central-southern Tuscany, Italy. This research provides a fairly complete picture of the fungal communities of these ecosystems, as well as the similarities and differences between them. The identification of exclusive differential species of each type of forest community provides information about the ecology of the different fungal species.Durant ces vingt dernières années, la communauté scientifique a montré un intérêt croissant au sujet des études concernant la biodiversité. La connaissance de la biodiversité est un préalable indispensable pour dresser une carte de la distribution des espèces et pour la conservation des organismes qui peuplent les écosystèmes. Les auteurs reportent les résultats de recherches mycocoenologiques dans plusieurs écosystèmes forestiers (chênaies sempervirentes de collines ou en situation côtière, châtaigneraies de colline et de montagne, sapinières naturelles et artificielles, chênaies caduques acidophiles et basiphiles) en Toscane centrale et du sud. Ce travail décrit de manière assez exhaustive les communautés fongiques des écosystèmes considérés ainsi que leurs ressemblances et différences. L’identification d’espèces différentielles exclusives de chaque type de communauté forestière permet de documenter l’écologie des diverses espèces de champignons.Laganà Angela, Salerni Elena, Barluzzi Carla, Perini Claudia.

Contribution to the knowledge of the Tatti Forests (Tuscany – Italy): mycofloristic investigations
No full textAs a contribution to knowledge of the fungal communities of thermophilous deciduous oak woods, 265
species of macromycetes are listed for the Tatti Forests (Tuscany, Italy), where Quercus cerris L.and
Q.petraea (Mattuschka) Liebl. grow together giving this area a very high naturalistic importance
Periodicity, fluctuations and successions of macrofungi in fir forests (Abies alba Miller) in Tuscany, Italy
No full textThe present study, carried out in natural and planted Abies alba Miller woods, was undertaken as a contribution to
knowledge of temporal changes occurring in fungal communities. Moreover, notes on fungal species and fungal communities
in this type of wood are given. Correlations between meteorological variables and fungi (number of species and number of carpophores, as total or divided into trophic groups) were tested by Pearson’s product-moment coefficient. On a short time
scale, weather parameters clearly play a major role, affecting periodicity and fluctuations; on a long time scale (10 years or more), correspondence analysis (CA) indicate that vegetation parameters and forest evolution affect successions
Macromycetes as long-term indicators of forest health and management in central Italy
No full textHere we report the results of a survey of three chestnut coppices in central-southern Tuscany (Italy). The aim of the study was to identify changes in macrofungal flora occurring over the years and to determine their possible causes. Coppices with different ages were chosen in order to obtain information on the effects of different types of management on the macrofungal communities. Changes were found over a period of about 20 years. The forests, however, are in good health according to the criteria proposed by Fellner (1985, 1987) and Schlechte (1987, 1991). The age and type of forest management seem to have a considerable role on the changes observed in the studied macrofungal communities
