ChemInform Abstract: Omphalotins E-I, Five Oxidatively Modified Nematicidal Cyclopeptides from Omphalotus olearius.
2009
Omphalotins E–I, oxidatively modified cyclic dodecapeptides, were isolated from mycelial extracts of the basidiomycete Omphalotus olearius, and their structures were determined by NMR spectroscopic and MS methods. Four of the five omphalotins contained an unprecedented N-hydroxylated tricyclic tryptophan derivative. All compounds exhibited strong and selective nematicidal activity against the plant pathogen Meloidogyne incognita with LD90 values between 2 and 5 μg mL–1. Cytotoxic activities were not detected up to 50 μg mL–1. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
Trophic habits of Muscardinus avellanarius (Mammalia Gliridae) as revealed by multiple stable isotope analysis
2007
Multiple stable isotope analysis was used to investigate the diet of the common dormouse Muscardinus avellanarius in a mixed Mediterranean forest. δ13C and δ15N values of dormouse tissues compared to those of the vegetal and animal sources available in the area showed that the isotopic composition of both adult and juvenile M. avellanarius could be explained by a mixture of vegetal and animal organic matter. The isotopic composition of the assimilated nitrogen was mostly explained by the organic matter from flora. Among the vegetal components, flowers of Fagus silvatica, Quercus robur, and the rarer Crataegus oxyacantha, berries of Ilex aquifolium and acorns of Q. robur were found in the ad…
Report WS1. Il binomio “Città porto”: conflitti e sinergie multilivello fra trasformazioni urbane e competitività globale
2012
The paper collects the best practices and considerations from two sessions of the workshop “Città porto: la dimensione multipla della pianificazione spaziale”. The leitmotiv of the first session’s reporters has been: the harbour, as urban gateway, origins conflicts, synergies and moments of cooperation with the urban structure. They’ve referred about North and South European harbours of medium level that, for advanced technical and logistic features and strategies of intervention, represent a substantial landmark for similar realities. Genoa, Rotterdam, Hamburg and Bilbao rehabilitation plans, despite their own peculiarities, have in fact dragged aspects of the industrial sector, urban desi…
Per una metodologia adeguata al riuso delle aree industriali dismesse - For an adequate methodology to reutilize derelict industrial areas
2013
Le aree industriali dismesse costituiscono "patrimonio" per diverse categorie di valore che deve essere recuperato e valorizzato. Il presente contributo propone obiettivi primari e secondari da condividere per il raggiungimento dell'obiettivo. Today the derelict industrial areasmight constitute an asset in terms of categories of various values that must be recuperated and preserved. The paper shows a series of primary and secondary goals that must be shared by the operators
design da materiali da ri-uso
2009
L’Eco-design, ovvero una progettazione orientata ai principi della sostenibilità ambientale, rappresenta uno strumento di importanza strategica, in quanto consente di prevenire, invece di rimediare, le conseguenze ambientali negative della produzione, dell’uso e dello smaltimento dei prodotti, contribuendo a definirne, oltre che la configurazione formale e tecnica, il profilo ambientale complessivo (qualità e quantità dei materiali impiegati; tecnologie e processi di produzione; modalità d’uso e manutenzione; modalità e scenari di dismissione, ad esempio riuso, riciclo, recupero energetico, compostaggio, ecc.). Infatti definire gli obiettivi e i requisiti ambientali di un prodotto, fin dall…
Desenvolupament de la psicomotricitat dels infants al medi natural: estrudi d'un cas
2022
Aquest treball pretén esbrinar aquelles habilitats motores que més es desenvolupen en contacte amb la natura en un grup multinivell d’educació infantil concret i conéixer el grau de destresa d'aquestes. Altrament, s'assenyalaran altres beneficis físics que s'adquireixen amb el contacte regular amb l'entorn natural i aquells aspectes positius per als infants amb TEA. Finalment, també es visibilitzarà la visió i les preferències dels infants respecte a aquestes activitats. Els mètodes utilitzats en aquest estudi han estat l'observació i l'entrevista. Pel que fa al primer mètode s'usaran fotografies i vídeos, gravacions amb notes de veu com una mena de quadern de camp i una taula d'observació.…
The size and shape of shells used by hermit crabs: A multivariate analysis of Clibanarius erythropus
2009
Shell attributes such as weight and shape affect the reproduction, growth, predator avoidance and behaviour of several hermit crab species. Although the importance of these attributes has been extensively investigated, it is still difficult to assess the relative role of size and shape. Multivariate techniques allow concise and efficient quantitative analysis of these multidimensional properties, and this paper aims to understand their role in determining patterns of hermit crab shell use. To this end, a multivariate approach based on a combination of size-unconstrained (shape) PCA and RDA ordination was used to model the biometrics of southern Mediterranean Clibanarius erythropus populatio…

The free-living planktonic freshwater bacterium Polynucleobacter necessarius subspecies asymbioticus (> 99% 16S rRNA similarity) represents a taxon with a cosmopolitan distribution and apparently ubiquitous occurrence in lentic freshwater habitats. We tested for intra-taxon biogeographic patterns by combining cultivation-independent and cultivation methods. A culture collection of 204 strains isolated from globally distributed freshwater habitats (Arctic to Antarctica) was investigated for phylogeographic patterns based on sequences of two markers, the 16S–23S internal transcribed spacers and the glutamine synthetase gene (glnA). Genetic distance between isolates showed significant geograph…

Measuring mutagenicity in ecotoxicology: A case study of Cd exposure in Chironomus riparius.
2021
Abstract Existing mutagenicity tests for metazoans lack the direct observation of enhanced germline mutation rates after exposure to anthropogenic substances, therefore being inefficient. Cadmium (Cd) is a metal described as a mutagen in mammalian cells and listed as a group 1 carcinogenic and mutagenic substance. But Cd mutagenesis mechanism is not yet clear. Therefore, in the present study, we propose a method coupling short-term mutation accumulation (MA) lines with subsequent whole genome sequencing (WGS) and a dedicated data analysis pipeline to investigate if chronic Cd exposure on Chironomus riparius can alter the rate at which de novo point mutations appear. Results show that Cd exp…
