Ferulago nodosa Subsp. geniculata (Guss.) Troia & Raimondo from Sicily (Italy): Isolation of Essential Oil and Evaluation of Its Bioactivity
2020
Ferulago nodosa (L.) Boiss. (Apiaceae) is a species occurring in the Balkan-Tyrrhenian area. The object of the present study is Sicilian F. nodosa subsp. geniculata (Guss.) Troia & Raimondo, classified as an endemic F. nodosa subspecies. Aerial parts of this plant species were subjected to hydrodistillation to obtain an essential oil. A total of 93 compounds were identified with 2,3,6-trimethyl benzaldehyde (19.0%), spathulenol (9.0%), (E)-caryophyllene (5.4%), and caryophyllene oxide (5.4%) as the main components. The biological activities of F. nodosa essential oil were also investigated. This oil showed an interesting antioxidant potential in a 2,2′-Azino-bis(3-ethylbenzothiazoline-6-sul…
Study of the mechanisms of oxidative stress, mitochondrial function and endoplasmic reticulum stress in obesity. Role in subclinical atherosclerosis …
2019
El aumento alarmante de la prevalencia de obesidad a nivel mundial y la enorme carga de enfermedad asociada ha generado una creciente demanda de estrategias para frenar la epidemia y / o mitigar los efectos dañinos de la obesidad sobre la salud. Para ello se requiere un compromiso firme y sinérgico por parte de todas las fuerzas sociales, no sólo para desarrollar estrategias preventivas, sino también para contribuir al conocimiento de los eventos patológicos y los mecanismos involucrados en el desarrollo de esta enfermedad. Por ello, el objetivo principal de la presente tesis doctoral es profundizar en los mecanismos subyacentes de la obesidad, especialmente en aquellos relacionados con el …
"Z ekologią za pan brat". Turystyka kulturowo-przyrodnicza na przykładzie parafialnego ogrodu botanicznego w Bujakowie (województwo śląskie)
2017
Przedmiotem niniejszego opracowania jest parafialny ogród botaniczny znajdujący się w jednej z miejscowości w województwie śląskim - Bujakowie (dzielnicy Mikołowa). Ogród o powierzchni 1 ha powstał w latach 70. XX wieku. Pomysłodawcą jego założenia był proboszcz miejscowego kościoła pw. św. Mikołaja. Bezpośrednio z funkcjonowaniem ogrodu związane jest ustanowienie w 2000 roku w Bujakowie sanktuarium Matki Bożej Bujakowskiej - patronki środowiska naturalnego. Dla mieszkańców miejscowości i okolic ogród pełni ważne funkcje (rekreacyjną, edukacyjną, ludyczną, kulturotwórczą), jest również rozpoznawalnym miejscem w turystyce przyrodniczej na obszarze województwa śląskiego.
ALLERGENS IN THE PARK AND GARDEN FLORA OF SICILY
2017
The ornamental flora of parks and gardens, as we know, generally includes high proportions of exotics. In Italy it arose from Renaissance on and increasingly enriched up to include a large proportion of exotics native to countries under Mediterranean and temperate climates. Similarly the garden flora of Sicily has a large number of mostly Mediterranean and subtropical exotics. Even if very similar on the whole, these floras differ in some floristic, biological and ecological features. Indeed, several succulent families and genera that are rare or missing in Italy are frequent in Sicily, but plants from temperate regions are almost absent in the island. As regards the allergenic patterns ref…
Principi di spontaneizzazione in Sicilia di Aesculus hippocastanum (Hippocastanaceae)
2009
The first record of Aesculus hippocastanum naturalized in Sicily is presented from a locality near the Alcantara river (Floresta, Messina) in the montane belt where decidous Turkey oak and chestnut woods are found. This species is not frequently cultivated in Sicily. In that locality several mature individuals likely introduced several decades ago occur.
Seasonality of intra-specific cell size in the phytoplankton of Lake Kinneret
2015
A distinct pattern of seasonal fluctuations in intra-specific cell size and/or colony size was observed in a large number of phytoplankton species from Lake Kinneret, Israel. The same species showed larger cell size or colony size in late winter and smaller size in late summer, with intermediate sizes in the interim periods. This phenomenon was exhibited by species of chlorophytes, dinoflagellates and cyanobacteria that were abundant enough to be sampled (fortnightly) and measured throughout the year. The annual pattern of fluctuations in size repeated itself over 8 consecutive years (2004-2012). The size fluctuations were independent of the temporal changes observed in cell abundance of ea…
La vegetazione del litorale di Manfria, presso Gela (Sicilia), area soggetta a vincolo archeologico.
2000
The results of a phytosociological investigation about a coastal area of S. Sicily, close to Gela, are presented. The coexistence of several lithological substrata, as well as the particular climatic conditions of this area, gives rise to a noteworthy floristic and vegetational biodiversity. As matter of fact, a set of N. African species are here localized, taking part to peculiar vegetation types, sometimes exclusive of this sicilian coast-stretch. The observed plant communities are represented by psammophilous associations of Cakiletea maritimae, Ammophiletea and Malcolmietalia, salt-marsh vegetation of Sarcocornietea and Phragmito-Magnocericetea, halophilous rupicolous shrublands of Crit…
The vegetation of mining dumps in SW-Sardinia
2005
The vegetation of mining dumps of SW-Sardinia includes several endemic or rare species, that have been confined to such artificial habitats by a millennial mining activity. The extreme edaphic specialisation of these species reflects with unusual fidelity the heterogeneity of substrata, therefore creating a system of plant communities that largely contributes to the environmental diversity of this part of the island. The phytosociological study presented in this paper recognized eight associations, distinguished by the cluster analysis in two main groups, the first including hemicrypto-chamaephytic vegetation, the second including nanophanerophytic garigues. Six associations are belonging t…
VegItaly: The Italian collaborative project for a national vegetation database
2012
Abstract Two years after its official start, the national vegetation database VegItaly, a collaborative project supported by the Italian scientific community and developed by a large group of scientists, is presented. This article offers a concise overview of the content of the database, currently consisting of 31,100 vegetation plot, including published and unpublished data. Some basic statistics are analysed; for example, data distribution in space and time, represented vegetation types expressed as physiognomic categories. Although rather young and still in progress, VegItaly already contains data from all the Italian regions and stands as an optimal candidate for the development of an I…
Orobanche centaurina Bertol. the correct name for O. kochii F.W. Schultz (Orobanchaceae)
2019
After the studying the original material of Orobanche centaurina Bertol. (Orobanchaceae) deposited in BOLO, a forgotten species described from Massa (Central Italy) parasitizing Centaurea paniculata L., and compared it with the type of O. kochii F.W. Schultz and with the types of others taxa actually considered synonyms of this, we concluded that the name of Bertoloni is the correct one for this species. Orobanche centaurina Bertol., nombre correcto para O. kochii F.W. Schultz (Orobanchaceae). Después de estudiar el material original de Orobanche centaurina Bertol. (Orobanchaceae) depo sitado en BOLO, una olvidada especie descrita de Massa (Italia central) parásita de Centaurea paniculata L…
