Abstract

The crater lake Lake Albano is an increasingly diminishing water resource in terms of volume, the lake level has dropped more than four meters since the 1960s, and water quality resulting from elevated levels of nitrogen and phosphorus. The area of the lake, and the volcano as a whole, is also considered to be geologically hazardous due to continual shallow seismic activity, gaseous emissions and hydrothermal activity. Therefore, most research has been focussed on the geological aspects of the Albano lake system, whilst long-term limnological studies have been lacking. A meromictic classification was given to the lake, but this was based on one year studies of the surface water only. Presented and discussed are the results of a water chemistry and biological study of the full depth profile of Lake Albano from 2004 to 2008. During winter 2005-2006 the lake underwent a complete overturn, resulting in an influx of nutrient rich hypolimnetic water into the upper productive layers and oxygenated epilimnetic water into the deepest water layers. The effect of full overturn on the phytoplankton community is described and compared with those of meromictic years. The interplay between natural and anthropological processes on water quality and water usages is also discussed.

15. L'Eros malinconico di l. U. Tarchetti

Author

Abstract

TI saggio cerca di evidenziare alcune possibili tracce delle correlazioni tra malinconia e scrittura, prendendo spunto dalla grande stagione romantica, ma attingendo in particolare all'opera dello "scapigliato" Tarchetti. E un'indagine sul temperamento malinconico, sui dissidi interiori del soggetto, sulle lacerazioni dei sentimenti inappagati, sull'inquietudine dell'artista di fine Ottocento che trova güt in alcuni romantici e in Leopardi irrinunciabili predecessori. Un viaggio nelle profondita nottume di Tarchetti con i suoi romanzi Paolina e Fosca e con il suo dilaniante confrontarsi con l"ombra", con la "donna fatale", con quell'eros malinconico ove vitae morte sfumano l'una nell'altra.

Abstract

The ecophysiological, cytomorphological, biochemical and molecular data presently available for the acidophilic red algal species Cyanidium caldarium, Cyanidioschyzon merolae and Galdieria sulphuraria are summarised. The taxonomic position of the three genera is discussed and emendements to the generic diagnosis are presented.

Abstract

Although N2-fixing cyanobacteria contribute significantly to oceanic sequestration of atmospheric CO2, little is known about how N2 fixation and carbon fixation (primary production) interact in natural populations of marine cyanobacteria. In a developing cyanobacterial bloom in the Baltic Sea, rates of N2 fixation (acetylene reduction) showed both diurnal and longer-term fluctuations. The latter reflected fluctuations in the nitrogen status of the cyanobacterial population and could be correlated with variations in the ratio of acetylene reduced to 15N2 assimilated. The value of this ratio may provide useful information about the release of newly fixed nitrogen by a cyanobacterial population. However, although the diurnal fluctuations in N2 fixation broadly paralleled diurnal fluctuations in carbon fixation, the longer-term fluctuations in these two processes were out of phase.

Abstract

Ecophysiological, morphological, ultrastructural, and phylogenetic methods were used to study nine strains of Galdieria isolated from different geographical regions in order to clarify the taxonomy and evolution of the genus and to understand the phylogeny of the Cyanidiales. The studied characters were often conserved in all of the isolates. Confocal laser scanning microscopy (CLSM) observations confirmed the presence of a single plastid and allowed its 3-D reconstruction. Phylogenetic analysis showed that all Galdieria isolates but one (G. maxima) form a strongly supported monophyletic lineage within the Cyanidiales. G. maxima is closely related to Cyanidioschyzon merolae and its taxonomic status needs to be revised. The Cyanidiales is an evolutionarily distinct group within the Rhodophyta. In spite of the uniform morphology among Galdieria strains, analysis of rbcL sequences showed moderate to high levels of sequence divergence within this genus. Apart from G. maxima, which is from Kunashir, Russia, the two other Russian isolates, G. daedala and G. partita grouped together with the remaining Galdieria taxa forming three separate clades. The Galdieria clades reflected the geographic site of origin of the isolates. On the basis of these data, we suggest that Galdieria (excluding G. maxima) represents a species complex. The limited sampling makes it difficult, however, to recommend changes to the existing classification system. We suggest that a broad and systematic study of Galdieria is required to understand fully the evolutionary history and taxonomy of this genus.
