A new species of Anthemis sect. Hiorthia (Asteraceae) from SE Sicily

A new species of Anthemis sect. Hiorthia (Asteraceae) is described from Sicily. This taxon, named A. piagnattiorum, is confined to a restricted area of the Hyblaean territory (SE Sicily), in the Natural Reserve of Cava Grande (Cassibile, Siracuse), where it takes shelter on carbonate rocky habitat and participates, with other Sicilian endemic taxa, to the composition of a termophilous chasmophytic community (Putorio calabricae–Micromerietum microphyllae).
The vascular flora of Nature Reserve “Pizzo Cane, Pizzo Trigna and Grotta Mazzamuto” (NW Sicily)
2009
A floristic investigation was carried out in “Pizzo Cane, Pizzo Trigna and Grotta Mazzamuto” Nature Reserve, one of the largest in Sicily. In spite of the considerable botanical interest of this area, few data were available from classic and recent literature. Based on field investigations, coupled with bibliographic and herbarium researches, we have listed 951 infrageneric taxa belonging to 103 families and 446 genera. A lot of these entities are reported in this area for the first time, for others ancient records are confirmed. Life form analysis shows the dominance of therophytes (44,79%) and hemicryptophytes (27,77%). From a chorological point of view, Mediterranean elements show a grea…
Phytophthora Diversity in a Sentinel Arboretum and in a Nature Reserve Area
2020
Most soilborne Phytophthora species are invasive plant pathogens and nursery plants for transplanting are considered a primary pathway for the introduction of exotic Phytophthora species into plant diversity conservation areas and sites. As a preliminary step toward investigating this subject, we compared the diversity of Phytophthora in the protected natural area Complesso Speleologico Villasmundo S. Alfio Nature Reserve (NR) (Melilli, Siracusa) and the botanical garden (BG) of the University of Catania (Catania), in eastern Sicily (southern Italy). Sampling was carried out during the spring of 2019. Overall 29 rhizosphere soil samples were collected, 17 from different types of vegetation …

Macrofungi as ecosystem resources: Conservation versus exploitation
2013
Fungi are organisms of significant importance not only for the crucial roles they undertake in nature but also for many human activities that are strictly dependent on them. Indeed, fungi possess fundamental positions in ecosystems functioning including nutrient cycles and wood decomposition. As concerns human-related activities, edible and non-edible mushrooms are also involved and/or exploited in forestry, pharmaceutical industry and food production; hence, nowadays they represent a major economic source worldwide. In order to maintain and improve their strategic importance, several conservation strategies, such as habitat preservation, are needed. This article reports several contributio…
