It was extended to the Mediterranean as part of an EU project. Initially programmed in FileMaker, the database was put on line in 1998, but it quickly became apparent that the internet demand for such information outstripped the capabilities of this software. In 2004, it was completely reprogrammed in MySQL, and named AlgaeBase. Although all Irish public funding abruptly ceased in 2008, we have managed to keep the data on-line. In 2012, sponsorship from Ocean Harvest, an Irish company, was received and this will allow us to continue for the present. AlgaeBase was intended to be an information source on the taxonomy and distribution of all algae, but it quickly became apparent that taxonomy is inseparable from nomenclature and we have been greatly assisted in this by having on-line access to the cards of Paul Silva"s Index Nominum Algarum. In recent years, we have put a lot of effort into adding PDFs of publications. In this we have been somewhat thwarted by the legal aspects of copyright; technically, we cannot offer PDFs of works before 1923. Nevertheless, we have managed to make available over 5,000 PDFs, many of rare and beautiful items found only in a handful of major libraries worldwide. Another issue is that of the legal requirements of the International Code of Nomenclature for Algae, Fungi, and Plants. Most problematical of all is the provision in Art. 13 for later-startingpoint dates for the families Nostocaceae, Desmidiaceae, and Oedogoniaceae (each in the original sense of defined publications). Many authors have seen fit to ignore these provisions. This is not the only article of the Code ignored by authors: many names published are invalid for reasons that some clearly regard as insignificant, or in ignorance of the requirements. In recent years, high-impact on-line journals in particular often completely ignore the necessities of the Code. Some of the conventions of taxonomy are also disregarded by authors; for example, the requirement for considering a genus taxonomically in terms of its type species. The considerable extent of this problem is evident in the number of genera that still have no type species designated, although some authors seem to have no issues with describing a new entity without even mentioning its type. Some recent taxonomic proposals are also invalid as the entity proposed included the type of another name. The proverb "Homo proponit, sed Deus disponit" can be applied to taxonomy in that one may be free to make any taxonomic proposals one wishes (provided somebody will publish them validly), but the final arbiter of acceptance is usually some authoritative source that surpasses all others. Essentially, like all the sciences, taxonomy is a web of hypotheses, the acceptance of which is based on the quality of the arguments presented. Unfortunately, AlgaeBase has, for some groups, become such an authoritative source for nomenclatural and taxonomic matters, which it was never intended to be.

An Italian triticalevariety and a bread wheat line, specifically bred for bioenergy applications, were used for comparison.

Cyanobacteria were collected in Antarctica during the Austral Summer Cruise 2004; the strains were isolated from South polar lakes sediments, soil and liken associations and subsequently they were grown in laboratory conditions before to be analysed. The strains belong to the genera of Nostocales and Oscillatoriales were morphologically identified by microscopy. The fatty acid composition varied among the strains with a relatively high quantity of polyunsaturated fatty acid production. A first genetic investigation by RAPD markers was performed. Cyanobacteria strains were also identified by ITS and TrnL sequencing. Antarctic cyanobacteria diversity and their geographical distribution revealed their particular tolerance range to harsh environmental conditions. We confirm that the successful classification of cyanobacteria species requires the application of multiple taxonomic criteri

(cardoon), exhibit interesting features for industrial biomass production as bioenergy crops, given also their advantageous adaptation capacities to typical Mediterranean climate trends, with noticeable resilience to drought and salinization stresses. The in situ hyperspectral reflectance responses of three genotypes of cardoon plants, irrigated with water at different salinity levels, have been tested for assessing the effects on their biophysical parameters, aiming at improving the biomass yield for bioenergy production, minimizing at same time the environmental impacts and the exploitation of soils and waters resources. The leaf and canopy reflectance hyperspectral signatures, acquired at three different growth stages with biometric measurements, were statistically analyzed (ANOVA, Tukey’s test, graphs), as noise-resilient spectral indices, sensible to different plant features of interest.

The ecological structure of the meadows was followed during the year 2004: physicochemical parameters were measured in conjunction with seagrass phenological parameters A high degree of genotypic homogeneity of the seagrass, confirmed by statistical analysis (NT-SYS Cluster), was observed in association to a high vegetative continued growth via rhizome extention. In this investigation we confirm that a high nutrient concentration, in water and sediment, determines a high density and biomass values of meadow. Other environmental factors, such as temperature, salinity and light, are important in controlling seasonal biomass and abundance of C. nodosa in these lakes. Finally different modes of reproduction, such as continued growth, via rhizome extension, into new locations and sexual offspring (seedling) recruitment, may contribute to low differentiation in the seagrass C. nodosa that can be considered as biological indicators for environmental quality in lagoon ecosystems
