Années arrosées et années sèches au Proche-Orient, relation avec la circulation atmosphérique régionale

2003

Les précipitations au Proche-Orient (Liban, Syrie, Jordanie, Territoire Autonome Palestinien, Israël) sont caractérisées par une grande variabilité, que ce soit à l’échelle interannuelle ou à l’échelle mensuelle. Pour cerner et expliquer cette variabilité, trois ensembles régionaux de co-variation ont été définis en utilisant les données mensuelles de 116 stations pour la période 1960-61/1989-90. Nous avons analysé la relation entre les années exceptionnellement arrosées ou sèches et la circulation atmosphérique régionale (données de réanalyses). Les précipitations dans les trois régions apparaissent très dépendantes de l’occurrence et de la position d’un talweg en altitude à l’est de la Mé…

Limited Stress Response to Transplantation in the Mediterranean Macroalga Ericaria amentacea, a Key Species for Marine Forest Restoration

2022

In the Mediterranean Sea, brown macroalgae represent the dominant species in intertidal and subtidal habitats. Despite conservation efforts, these canopy-forming species showed a dramatic decline, highlighting the urge for active intervention to regenerate self-sustaining populations. For this reason, the restoration of macroalgae forests through transplantation has been recognized as a promising approach. However, the potential stress caused by the handling of thalli has never been assessed. Here, we used a manipulative approach to assess the transplant-induced stress in the Mediterranean Ericaria amentacea, through the analysis of biochemical proxies, i.e., phenolic compounds, lipids, and…

Green coffee, bioactive compounds’ analysis of experimental cultivation in Sicily: a new frontier in the Sicilian food sector

2023

Recently, climate change represents a new possibility for tropical cultivars fruit in Mediterranean areas. The focus of this work is the evaluation of the real possibility of coffee cultivation in Sicily, like coffee plants grown in tropical and subtropical regions. The objective was to evaluate plant adaptation to our climate and to study the chemical qualities of green coffee pulps and seeds: total phenolic content, antiradical capacity, fatty acids, amino acids, alkaloids, vitamins, proximate composition, polyphenolic profile and other bioactive compounds of cosmetic, pharmaceutical and agrary interest. Temperature, light and vegetative growth of Coffea arabica L. cv. “Caturra” plants we…

Effects of cold acclimation and dsRNA injections on Gs1l gene splicing in Drosophila montana

2017

Abstract Alternative splicing, in which one gene produce multiple transcripts, may influence how adaptive genes respond to specific environments. A newly produced transcriptome of Drosophila montana shows the Gs1-like (Gs1l) gene to express multiple splice variants and to be down regulated in cold acclimated flies with increased cold tolerance. Gs1l’s effect on cold tolerance was further tested by injecting cold acclimated and non-acclimated flies from two distantly located northern and southern fly populations with double stranded RNA (dsRNA) targeting Gs1l. While both populations had similar cold acclimation responses, dsRNA injections only effected the northern population. The nature of …

Inducing Cold-Sensitivity in the Frigophilic Fly Drosophila montana by RNAi

2016

The work was supported by CNPq (Fellowship to FMV) and a NERC Studentship to DJP. Cold acclimation is a critical physiological adaptation for coping with seasonal cold. By increasing their cold tolerance individuals can remain active for longer at the onset of winter and can recover more quickly from a cold shock. In insects, despite many physiological studies, little is known about the genetic basis of cold acclimation. Recently, transcriptomic analyses in Drosophila virilis and D.montana revealed candidate genes for cold acclimation by identifying genes upregulated during exposure to cold. Here, we test the role of myo-inositol-1-phosphate synthase (Inos), in cold tolerance in D. montana …
