On the pyrophytism in the Mediterranean area

2015

Authors briefly present some observations and reflections on the “seeding strategy” of some plant species (Cistus spp., Cistaceae, in particular) in the Mediterranean area in relation to fire: they conclude it does not seem a specific adaptation to wildfires (as suggested in a relevant part of the recent literature), but a generalistic adaptation to open, high energy and variable habitats with aleatory fluctuations. The difference is important both for theoretical and applied aspects, e.g. for the correct management of Cistus species and of other Mediterranean species and habitats. Fire is undoubtedly a major ecological factor in the Mediterranean area. Many botanists have postulated the re…

Comparative Study of Several Machine Learning Algorithms for Classification of Unifloral Honeys

2021

Unifloral honeys are highly demanded by honey consumers, especially in Europe. To ensure that a honey belongs to a very appreciated botanical class, the classical methodology is palynological analysis to identify and count pollen grains. Highly trained personnel are needed to perform this task, which complicates the characterization of honey botanical origins. Organoleptic assessment of honey by expert personnel helps to confirm such classification. In this study, the ability of different machine learning (ML) algorithms to correctly classify seven types of Spanish honeys of single botanical origins (rosemary, citrus, lavender, sunflower, eucalyptus, heather and forest honeydew) was investi…

Polyamines and microbiota in bicuspid and tricuspid aortic valve aortopathy

2019

Polyamines are small aliphatic cationic molecules synthesized via a highly regulated pathway and involved in general molecular and cellular phenomena. Both mammalian cells and microorganisms synthesize polyamines, and both sources may contribute to the presence of polyamines in the circulation. The dominant location for microorganisms within the body is the gut. Accordingly, the gut microbiota probably synthesizes most of the polyamines in the circulation in addition to those produced by the mammalian host cells. Polyamines are mandatory for cellular growth and proliferation. Established evidence suggests that the polyamine spermidine prolongs lifespan and improves cardiovascular health in …

Michele Lojacono-Pojero’s Centuriae in the herbaria and archives in Geneva

2012

Lojacono, well known as the author of a Flora sicula, offered for sale and distributed various exsiccata. In particular, he prepared 7 Centuriae of Plantae siculae rariores (1879-1884) and 4 Centuriae of Plantae italicae selectae (1885-1888). Swiss botanists (Barbey, Boissier, Burnat) were among his first customers. From their legacy, printed, mostly autographic inventories of all but one of these Centuriae (with only the second Italian Centuria missing) came to the archives of the Conservatoire botanique in Geneva, some in two different versions. These rare documents have been dated with the aid of mail stamps and of correspondence kept in the same archives, and transcripts of all of them …

The Herbarium of Antoine Bras (1803-1883)

2012

Bras, distinguished French amateur botanist and author of a catalogue of the flora of his home province (département de l’Aveyron), built a considerable personal herbarium through 50 years of active collecting (1833-1882). That herbarium, long believed lost, was auctioned in 2008 and acquired by the first author for the Palermo Herbarium (PAL-Gr). Its c. 25,000 specimens are being mounted and databased, with a view of making the digital images and label data available for online consultation. An analysis based on a first sample of 1550 specimens is presented, with explanations of Bras’ labelling and numbering systems and a list of other collectors and correspondents (81 to date) who contrib…

Natura e architettura nel giardino di Villa Florio-Pignatelli (Palermo, Sicilia).

2003

ABSTRACT.– Amongst the Sicilian historical gardens it is merited to remember the ornamental garden design of Villa Florio- Pignatelli, situated in the western periphery of Palermo. The building, and probably the garden too, are from the second half of the 18. century. This article contains the result of a cognitive study of its history, architecture and vegetal composition, based on field studies in the garden itself, on bibliographical and archival work. In 1838 it was sold by the Duke of Cumia to Vincenzo Florio, who in following conceded it to his son Ignazio. Already at this time, there was a garden with a "flora all’Italiana" behind the Villa, which had circular vials in radial order, …
