Shifts in plankton assemblages promoted by free water surface constructed wetlands and their implications in eutrophication remediation
2015
Abstract Two units of free water surface constructed wetlands (FWSCWs) were created in 2009 in a Mediterranean protected site, the Albufera de Valencia Natural Park, to treat eutrophic inflows to the Albufera de Valencia lagoon, the largest coastal lagoon in the Iberian Peninsula, affected by cultural eutrophication. Data of phytoplankton and zooplankton biomass and richness of the inflows and outflows corresponding to the first 3.5 years of operation of the system have been analyzed to evaluate the role of plankton in the eutrophication reversion. The FWSCWs significantly reduced the exported microalgal biomass, stimulated the potential mixotrophic groups of phytoplankton such as Euglenoph…
The effects of post-pasture woody plant colonization on soil and aboveground litter carbon and nitrogen along a bioclimatic transect.
2013
Abstract: We investigated the effects of woody plant colonization of abandoned pastures on soil and litter organic carbon (C) stocks and nitrogen (N) content along a bioclimatic transect in a semi-arid environment (Sicily, Italy). Soil samples were taken in three successional stages (grazed pasture, shrubland, forest) within each of three bioclimates (supramediterranean - “supra”, mesomediterranean - “meso”, thermomediterranean - “thermo”). Organic C and N in litter and soil (0-10 cm and 10-30 cm depth) were determined, as well as soil bulk density. Especially at 0-10 cm depth, changes in C and N contents along successional stages differed among bioclimates. Soil organic carbon (SOC) stock …
Terpenoid composition and origin of amber from the Cape York Peninsula, Australia
2014
The terpenoid composition of fossil resin from the Cape York Peninsula, Australia has been analysed by pyrolysis-gas chromatography-mass spectrometry (Py-GC-MS) to determine its origin. The pyrolysis products were dominated by cadalene-based C15 bicyclic sesquiterpenoids including some C30–C31 bicadinanes and bicadinenes typical of Class II resin derived from angiosperm plants of Dipterocarpaceae. This observation contrasts with the Araucariaceae (Agathis sp.) source previously suggested for the resin based on Fourier transform infrared (FTIR) analyses. Dipterocarpaceae are not known in Australian vegetation but grow abundantly in Southeast Asia including New Guinea, indicating that the geo…
The role of eutrophication reduction of two small man-made Mediterranean lagoons in the context of a broader remediation system: Effects on water qua…
2013
In order to meet the requirements of the European Union Water Framework Directive for the Albufera de Valencia (AV) Natural Park, in 2009, several areas of free water surface constructed wetlands (FWSCWs) planted with emergent vegetation and two small shallow lagoons planted with submerged macrophytes were created over a 40-ha area formerly occupied by rice fields. This area is currently a reserve known as Tancat de la Pipa. The dual goal of this programme was to improve the quality of the hyper-eutrophicated waters of the AV lagoon, the largest littoral lagoon in the Iberian Peninsula, and to restore former lost habitats to increase the biodiversity of the area. The lagoons were mainly fed…
Soviet era landscape change and the post-Soviet legacy in Latvia
2019
The collectivisation of agriculture and the development and application of land improvement “melioration” programmes and technologies, as well as the construction of kolkhoz centres during the Soviet era in Latvia was extensive and has a legacy on the post-Soviet landscape and agricultural economy. A study of a number of rural municipalities in different landscape types, through the comparison of maps from the early 20th century with those from around 2000, and one example with maps from the 1960s and 1990s, together with field work, revealed the degree of change that had taken place. In particular, there was a significant increase in forest – despite the kolkhoz system being targeted at in…
Islands of Fire. Stromboli in the documentary by Vittorio De Seta
2020
The present contribution is based on the methodological approach and on the typical objectives of cultural geography that sees the cultural work as an important source to read the territorial and landscape contexts. Through this paper we then want to critically report about the 1954 short documentary Isole di Fuoco (Islands of Fire), awarded in Cannes, that the director Vittorio De Seta mainly shot on the volcanic island of Stromboli, in Sicily, during an eruption occurred in 1954.
Music in the Dark: Soundscapes in Christiane Ritter’s A Woman in The Polar Night
2020
In A Woman in the Polar Night (Eine Frau erlebt die Polarnacht, 1938), Christiane Ritter, a well-to-do Austrian housewife, describes her experience as the first central European woman to overwinter on Svalbard (1934–35). Ritter’s prose is extraordinary in its lyrical simplicity, and in German editions the text is interspersed with her paintings of the scenes that at first were so alien and changing, yet became so familiar and loved.
 Although stationed on the north coast of Svalbard with minimal human contact and without any recourse to the music with which Ritter had been surrounded in Austria, A Woman in the Polar Night is a text that is full of references to sound, natural sounds th…
Habitat preference of endangered Eastern Iberian Reed BuntingsEmberiza schoeniclus witherbyi
2011
Capsule Careful management is required to maintain or create habitats with the correct proportions of rush with reeds that are preferred by this subspecies. Aims To determine the habitat requirements of Eastern Iberian (Western Iberian Reed Buntings were not included in the study) Reed Buntings Emberiza schoeniclus witherbyi, a subspecies endemic to a few marshes in France, Spain and Morocco, with a population of 254–360 breeding pairs. Methods Twenty-five wetlands in Spain were surveyed and presence/absence of Iberian Reed Buntings was deteremined together with data on 41 environmental variables. The relationships between the birds and habitat data were investigated using glm. Results Prop…
Morphological characterization of calanchi (badland) hillslope connectivity
2017
Calanchi, a type of Italian badlands created by a combination of water erosion processes and local geomorphological and tectonic controls, is a striking example of long-term landscape evolution. In small temporal/spatial scales, the calanchi exhibit many of the geomorphic processes and landforms that may be observed in fluvial landscapes, hence they may be considered as micro-basins where geomorphic dynamics and landscape features can be related. The goal of this research is testing the use of simple morphometric variables for assessing sediment connectivity of calanchi landforms. In order to detect the morphological characteristics controlling the landscape connectivity of calanchi basins,…
