Estudio anatómico-histológico de las flores del endemismo Lamottea diania (Asteraceae) y de los efectos del ozono troposférico sobre su desarrollo.
2016
"Estudio anatómico-histológico de las flores del endemismo Lamottea diania (Asteraceae) y de los efectos del ozono troposférico sobre su desarrollo". Lilloa 53 (2). Plantas del endemismo Lamottea diania se expusieron en cámaras OTC (Open Top Chambers) a aire ambiente filtrado y a aire ambiente no filtrado más 30 ppb de ozono para observar el efecto de este contaminante sobre el desarrollo de sus flores, particularmente sobre su androceo. Hemos comprobado, mediante estudios de microscopía óptica y electrónica, que el ozono afecta el proceso de desarrollo y maduración de los estambres y del polen. Las anteras se ven afectadas, en unos casos al abortar algunos estambres en su desarrollo y, en …
Microbial Diversity in the Midguts of Field and Lab-Reared Populations of the European Corn Borer Ostrinia nubilalis
2011
Background: Insects are associated with microorganisms that contribute to the digestion and processing of nutrients. The European Corn Borer (ECB) is a moth present world-wide, causing severe economical damage as a pest on corn and other crops. In the present work, we give a detailed view of the complexity of the microorganisms forming the ECB midgut microbiota with the objective of comparing the biodiversity of the midgut-associated microbiota and explore their potential as a source of genes and enzymes with biotechnological applications. Methodological/Principal Findings: A high-throughput sequencing approach has been used to identify bacterial species, genes and metabolic pathways, parti…
Microbial and chemical changes in 'Sobrasada' during ripening.
1993
‘Sobrasada’ is a raw-cured product typical of Mallorca (Balearic Islands). Throughout its ripening process the product, like other raw-cured sausages, undergoes a series of chemical and microbial changes which lead to the formation of its desirable final characteristics. In the ‘sobrasada’ studied, the breeds, feeding and casings used in the Balearic Islands were employed. The evolution of different groups of microorganisms was followed: mesophylic aerobic microorganisms, lactic acid bacteria, Enterobacteriaceae, yeasts and moulds, group D Streptococcus, proteolytic microorganisms and lipolytic microorganisms. It was found that the predominant flora, from the beginning to the end, was made …
Le piante nella flora spontanea della Sicilia

La flora vascolare e lichenica della Riserva Naturale Grotta Conza (Sicilia nord-occidentale). – Naturalista sicil., s. 4, 33 (1-2): 3-68.
2009
Vascular and lichenic flora of Grotta Conza Nature Reserve (NW Sicily). Based on field investigation, bibliographic and herbarium researches we present a vascular and lichen flora of Grotta Conza Nature Reserve, a protected area of speleological and antropological interest located along the northern slopes of Pizzo Manolfo, very close the city of Palermo. The main outcrops of the area are represented by limestones of mesozoic and tertiary origin, while, bioclimate can be referred to thermomediterranean thermotype with subhumid ombrotype. Landscape, strongly influenced by the past prolonged historical utilization of the territory, shows total absence of primary woodlands, whose place is now …

Biodiversity and evolution of the dendroflora in the Mediterranean
2012
The main old representatives of the Mediterranean dendroflora, their origin and distribution are treated. Relevant threats and strategy for in situ and ex situ conservation are also discussed here.
Ellenberg Indicator Values for the vascular flora alien to Italy
2018
Studies to date about plants alien to Italy have had limited focus on the ecology of this component of the flora. Ellenberg's indicator values are a useful tool to delineate the relationship between plants and environment, recognizing for each species a functional role as biological indicator; these values have been proposed for estimating the influence of the main environmental factors in determining flora and vegetation changes on a specific surface area. This contribution includes a list of 1206 taxa of plants naturalized in at least one administrative region or casual in at least three regions of Italy. In addition, some methodological considerations on the attribution and use of Ellenb…
The gut microbiota: An emerging risk factor for cardiovascular and cerebrovascular disease
2018
Commensal gut microbiota have recently been implicated in cardiovascular disease (CVD) and cerebrovascular disease. Atherosclerotic plaque formation depends on the colonization status of the host. In addition to host nutrition and the related microbiota-dependent metabolic changes, activation of innate immune pathways triggers the development of atherosclerosis and supports arterial thrombosis. Gnotobiotic mouse models have uncovered that activation of Toll-like receptor-2 by gut microbial ligands supports von Willebrand factor-integrin mediated platelet deposition to the site of vascular injury. Depending on nutritional factors, the microbiota-derived choline-metabolite trimethylamine N-ox…
