SICILY AS THEORETICAL MODEL TO STUDY THE POTENTIAL IMPACT OF GENETICALLY MODIFIED PLANTS IN A HOTSPOTS OF BIODIVERSITY
2015
In Europe, especially in Italy, different considerations are necessary when potential GMPs are to be grown. In particular high biodiversity areas such as Sicily should have a more detail plans of potential benefits and risks assuring the conservation of biodiversity and endemic species. Sicily is one of the most relevant biodiversity hotspots in the Mediterranean area, with a vascular flora of 3252 species and 321 endemic taxa. Considering the latest IUCN categories and criteria, 401 taxa (12.4% of Sicilian flora) are under threat (categories “CR”, “EN”, “VU”), and 220 more taxa (6.8%) are “Near Threatened”. Sicily is also known to have a rich butterfly and coleopteran fauna including endem…
Pesticides: Chemical and Biological.
2013
There is a requirement by World Health Organization (WHO), Food and Agriculture Organization (FAO) and other International Organizations to develop environmentally sustainable systems for controlling pests that are less reliant on chemical pesticides as the primary management tool. However biological control alone cannot at the moment solve all pest problems and must be considered instrument to be used in combination with other methods. Compatibility of chemical pesticides (CP) and biological pesticides (BP) is one of the key for the implementation of Integrated Pest Management (IPM) programs. Testing the compatibility of CP and BP is necessary if these two agents are to be applied together…
Organismi geneticamente modificati (OGM): quali rischi per la biodiversità zoologica?
2010
Diversi OGM possono potenzialmente entrare nel mercato e in generale nell’ambiente italiano. In particolare i candidati più prossimi sono le piante geneticamente modificate (PGM) tolleranti agli erbicidi e resistenti agli insetti, ma sono in corso di valutazione anche insetti e pesci transgenici per i quali l’Autorita’ Europea per la Sicurezza Alimentare (EFSA) ha già dato mandato per una revisione scientifica dello stato dell’arte e per lo studio della valutazione del rischio (EFSA, 2008 e 2009). Accanto ai benefici dello sviluppo di questi organismi è importante ricordare alcuni rischi ambientali collegati proprio al loro sviluppo: trasmissione del gene modificato ad altre piante attraver…
Response to Kruse-Plass et al. (2017) regarding the risk to non-target lepidopteran larvae exposed to pollen from one or more of three Bt maize event…
2017
We respond to the paper of Kruse-Plass et al. (Environ Sci Eur 29:12, 2017), published in this journal, regarding the risk to non-target lepidopteran larvae exposed to pollen from one or more of three Bt maize events (MON810, Bt11 and 1507). We emphasise that what is important for environmental risk assessment is not the number of pollen grains per se, but the degree of exposure of a NT lepidopteran larva to Bt protein contained in maize pollen. The main text of this response deals with general issues which Kruse-Plass et al. have failed to understand; more detailed refutations of each of their claims are given in Additional file 1. Valid environmental risk assessment requires direct measur…
EFFECT OF Bacillus thuringiensis ON RESPIRATION RATES OF MARINE INTERTIDAL MYTILASTER INTERTIDAL, MYTILASTER MINIMUS (MOLLUSCA, BIVALVIA)
2010
Increasing body of research deals with the impact of agricultural products marine environment. Indeed it is expected to detect insecticides, including the ones for biocontrol, in nearshore marine waters and thus predicting where, when and with what magnitude these impacts are most likely to occur is imperative if we are effectively interested in understanding the role of biological products as Bacillus thuringiensis (Bt) on marine biodiversity. Bivalves are important elements of marine biodiversity and very often they play a role of ecosystem engineers in that many other species structurally depend on their presence. Oxygen consumption through respiration in these organisms varies with natu…
High precision mass measurements for wine metabolomics
2014
An overview of the critical steps for the non-targeted Ultra-High Performance Liquid Chromatography coupled with Quadrupole Time-of-Flight Mass Spectrometry (UPLC-Q-ToF-MS) analysis of wine chemistry is given, ranging from the study design, data preprocessing and statistical analyses, to markers identification. UPLC-Q-ToF-MS data was enhanced by the alignment of exact mass data from FTICR-MS, and marker peaks were identified using UPLC-Q-ToF-MS(2). In combination with multivariate statistical tools and the annotation of peaks with metabolites from relevant databases, this analytical process provides a fine description of the chemical complexity of wines, as exemplified in the case of red (P…
