Northernmost occurrence of the offshore rockfish, <i>Pontinus kuhlii</i> (Scorpaeniformes: Scorpaenidae), in the Mediterranean sea

An adult male specimen of the offshore rockfish, Pontinus kuhlii (Bowdich, 1825), was caught off the coast of Alghero (NW Sardinia, Italy) in August 2004. That capture represents the second documented record of this Atlantic migrant in Italian waters, after more than a century from the first report. Furthermore, the new specimen is the largest specimen of this species ever recorded in the Mediterranean Basin and the most northern capture for this geographic area. Morphologic and meristic characters of the collected fish are described and the existence of a Mediterranean population is hypothesized

Active-alkali metal promoted reductive desulfurization of dibenzothiophene and its hindered analogues

Reductive desulfurisation of organic compounds is of importance both in organic synthesis and in industry. Benzo- and dibenzothiophenes are between the most abundant sulphur containing impurities in crude oils, and their desulfurization is a mandatory issue in the production of non polluting fuels. Following our interest in the development of efficient alkali metal-mediated synthetic procedures and alternative protocols for the chemical transformation of widespread environmental contaminants we wish to report here on the effectiveness of sodium and lithium metals, in the presence of catalytic amounts of tetraphenylethylene (TPE), in promoting the reductive desulfurization of dibenzothiophene, as well as of the corresponding sulfone and sulfoxide

Ati, the Indigenous People of Panay: Their Journey, Ancestral Birthright and Loss

This research investigates the Ati people, the indigenous people of Panay Island, Philippines— their origins, current economic status, ancestral rights, development issues, and challenges. This particular inquiry draws attention to the history of the Ati people ( also known as Aetas, Aytas, Agtas, Batak, Mamanwa ) as the first settlers of the islands. In contrast to this, a festive reenactment portraying Ati people dancing in the tourism sponsored Dinagyang and Ati-Atihan festival will be explored. This paper aims to compare the displacement of the Ati as marginalized minorities in contrast to how they are celebrated and portrayed in the dance festivals

Le Trappole a feromoni nella lotta al <i>Prays oleae</i> bern.

Researches carried out from 1980 to 1983 in Sardinian oil-producing olive groves investigated Prays oleae infestations by examining weekly 300-600 flower clusters or newly-formed olives. The trend of male catches was examined weekly (in some groves daily) using 3-6 pheromone traps in each grove. The daily catches revealed the influence of climatic factors, trends being similar in the same zone even between groves distant from each other. A strict correspondence was observed between catches, each in sect generation development and plant vegetative stages. Anthophagous generation catches proved to be the most numerous (June-July), and carpophagous generally the least. Peak oviposition occurred on the drupes when the newly·formed olives began to enlarge, and anthophagous male catches were maximum. Thus, pheromone traps offer an excellent means of establishing the correct time for insecticidal treatment against the eggs and newly-hatched larvae of the carpophagous generation. No correlation was found between anthophagous male catches and oviposition on the olives nor between the number of eggs and larvae boring into the kernel. Up to the moment, therefore, it has not been possible to determine an intervention threshold based on pheromone trap captures

Fitofarmaci e ambiente naturale

È noto che nelle nazioni ad economia avanzata, i pesticidi sono parte integrale dei sistemi di produzione agricola. Essi prevengono o limitano le perdite dovute ad organismi nocivi, rendono possibile agli agricoltori di avere produzioni regolari, di alta qualità (?), di razionalizzare e intensificare i sistemi di coltivazione. Non conosciamo i danni all'ambiente ed all'uomo indotti dall'immissione di tutte queste sostanze nell'ambiente Sardo, ma alla luce di quanto conosciuto in altre parti del mondo questi devono essere senza dubbio molto gravi. Per questo, molto si può fare e qualcosa si va facendo in Sardegna per ridurre un inquinamento infido, molto difficile da controllare e rilevare
