New records of corticioid fungi from Sicily

2016

This paper is the result of an on-going study on distribution and ecology of corticioid wood-inhabiting fungi in Sicily. Twenty-five species not previously recorded in Sicily are here listed. For each taxon, ecological and distributional data are provided. Subulicystidium perlongisporum was recorded in Italy for the first time in two localities occurring on Quercus ilex L. wood. Description, distributional and ecological data of this rare taxon are also provided. Dendrophora versiformis and Kavinia alboviridis, considered rare species in Italy and Europe, are included in this report.

Monoterpene derivatives from the flowers of Ferulago campestris, (Apiaceae).

2013

Ferulago campestris (Besser) Grec., (Ferula galbanifera (Mill) Kock. = F. campestris), finocchiazzo, is an annual or perennial herb of the Mediterranean area. In this paper the phytochemical studies of the CH2Cl2 and MeOH extracts of the flowers are described. Several ferulol derivatives and a new 10-hydroxy-verbenone ester (7) were isolated. The structure of the new compound was established by extensive NMR analysis, including HMBC and HSQC pulse sequences.

Remote sensing of solar-induced chlorophyll fluorescence: Review of methods and applications

2009

Interest in remote sensing (RS) of solar-induced chlorophyll fluorescence (F) by terrestrial vegetation is motivated by the link of F to photosynthetic efficiency which could be exploited for large scale monitoring of plant status and functioning. Today, passive RS of F is feasible with different prototypes and commercial ground-based, airborne, and even spaceborne instruments under certain conditions. This interest is generating an increasing number of research projects linking F and RS, such as the development of new F remote retrieval techniques, the understanding of the link between the F signal and vegetation physiology and the feasibility of a satellite mission specifically designed f…

Advances in the knowledge of South African Riella (Sphaerocarpales) and a new endemic species, Riella trigonospora

2014

Cultures of soil sediments collected in June 2012 from saltpans and vleis from five South African localities have revealed two new, geographically distant, populations of the endemic Riella alatospora, confirmed the presence of Riella purpureospora from Blouvlei in the Cape Town area and uncovered a new endemic species, Riella trigonospora. The new species obtained from cultures from five sampled localities is described and illustrated. It is dioicous and characterised by acuminate to rostrate, papillose involucres and by a unique spore morphology. The spores are dark purple, as in R. purpureospora, and have an irregular discontinuous wing at the equatorial plane, which suggests a morpholog…

Riella bialata Trab. (Riellaceae, Marchantiophyta): A new addition to the European liverwort flora

2013

[EN] Riella (Riellaceae, Sphaerocarpales) is a genus of aquatic liverworts with a disjunct worldwide distribution in areas of seasonal Mediterranean-type climates. Its centre of diversity is located in the Mediterranean basin, where about half the species number of the genus is concentrated. In the course of a worldwide revision of the genus Riella, plants from a monoicous species with wingless, not papillose and smooth involucres were found in two distant Iberian localities. These plants showed a geminate dorsal wing, unlike the single wing occurring in the remaining species of the genus. This character unambiguously assigns these populations to R. bialata, a species known to date from a s…

Herbicidal potential of aqueous extracts from Melia azedarach L., Artemisia arborescens L., Rhus coriaria L. and Lantana camara L.

2017

In the search for new strategies for weed management in agricultural systems, a great interest is to use the plant extracts to replace or integrate, chemical weed control. Two experiments were done to test the effects of plant water extracts from Chinaberry (Melia azedarach L.), Tree Wormwood (Artemisia arborescens (Vaill.) L.), Sicilian Sumac (Rhus coriaria L.) and Lantana (Lantana camara L.) on seed germination of Rocket (Eruca sativa Mill.), Rapeseed (Brassica napus L.), Bladderflower (Araujia sericifera Brot.) and Psyllium (Plantago psyllium L). The water extracts (pure and 50% mixtures) from the donor species were applied on seeds of recipient plants. In second experiment in pots, thes…

The use of artificial nest-boxes by Apodemus sylvaticus dichrurus in Sicily

2008

Reports of wood mouse arboreality are rather scarce outside Britain. I reviewed and analysed 267 visits and 16.456 checks of glirids artificial nest-boxes mounted on trees, in twelve sample areas of Meso- and Supra-Mediterranean woodlands (Sicily, 1995-2005). The wood mouse was recorded only 65 times (0.395%) using the artificial nest-boxes in nine sample areas, and based on this low frequency, the wood mouse can be considered as an occasional dweller of artificial nest-boxes. The resource selection index allowed checking the use respect to the availability of nest-boxes placed at different heights. These were likely reached by climbing the dense understorey and low tree branches up to 5 m,…

Factors influencing the distribution, abundance and nest-site selection of an endangered Egyptian vulture (Neophron percnopterus) population in Sicily

2003

Egyptian vulture (Neophrom percnopterus) breeds in Sicily and, in 22 years of monitoring, has shown a decline followed by a slight recovery. We used Generalised Linear Models to predict: (1) the distribution range, (2) the habitat selection within the range, (3) the quality (i.e., occupation rate, breeding success) of breeding sites. Some 60% of Sicily proved to be unsuitable, being either too densely forested and without cliffs for nesting, or too densely populated, along with intensive agriculture. The models converged, indicating that the pairs select a precise upland habitat where low cliffs, distant from urban areas, are surrounded by arboreal crops and Mediterranean vegetation. The va…
