Comparative analysis of the proximate and elemental composition of the blue crab Callinectes sapidus, the warty crab Eriphia verrucosa, and the edibl…

2016

AbstractThe proximate composition and element contents of claw muscle tissue of Atlantic blue crabs (Callinectes sapidus) were compared with the native warty crab (Eriphia verrucosa) and the commercially edible crab (Cancer pagurus). The scope of the analysis was to profile the chemical characteristics and nutritive value of the three crab species. Elemental fingerprints showed significant inter-specific differences, whereas non-significant variations in the moisture and ash contents were observed. In the blue crab, protein content was significantly lower than in the other two species, while its carbon content resulted lower than that characterizing only the warty crab. Among micro-elements…

Integrative effects of vine water relations and grape ripeness level of vitis vinifera L. cv. Shiraz/Richter 99. II. grape composition and wine quali…

2016

Regulation of grapevine water status is a common practice to manipulate grape composition and wine quality. In this investigation the effect of plant water status (two field water capacity-based irrigation levels, 75% and 100%, applied at single and combined vine developmental stages) and ripeness level (harvesting at different soluble solid levels) on grape composition and wine quality of Vitis vinifera L. cv. Shiraz/ Richter 99 was determined. Integrative effects of vine water relations and grape ripeness level, specifically in a Mediterranean high winter rainfall area, have not yet been investigated systematically.

Defoliation of two-wire vertical trellis: effect on grape quality

2017

ABSTRACTBasal leaves were removed from Cabernet Sauvignon vines trained to a two-wire vertical trellis at fruit set and at veraison. Leaf removal did not modify total soluble solids and titratable acidity at harvest. Defoliation at fruit set of lower cordon recovered the grape anthocyanin composition gap between upper and lower cordons and that produced a positive effect on anthocyanin synthesis. Hence, control of the upper cordon and defoliation of fruit set of the lower cordon treatments showed comparable values of anthocyanins. Defoliation at veraison did not produce any appreciable effect. This study shows that skin anthocyanin composition in a two-wire vertical trellis can be modified …

Palaearctic species of Charipinae (Hymenoptera, Figitidae): two new species, synthesis and identification key

2018

The Charipinae Dalla Torre & Kieffer, 1910 present in the Palaearctic region are revised; 2410 specimens have been identified, belonging to 75 species: 52 to Alloxysta, one to Apocharips, six to Dilyta and 16 to Phaenoglyphis. For 33 species, new country-level distribution records are provided. Two new species are here described: Alloxysta palearctica Ferrer-Suay & Pujade-Villar sp. nov. and Alloxysta pascuali Ferrer-Suay sp. nov. A diagnosis for these species is included and their diagnostic features are shown in different figures. A key to identify all the species of Charipinae in the Palaearctic region is also given.

2020

Charipinae (Cynipoidea: Figitidae) deposited in the Museum of Natural History of Wroclaw University (Poland) have been studied. Seven species are recorded for the first time from Poland: Alloxysta brachyptera (Hartig, 1840), A. castanea (Hartig, 1841), A. citripes (Thomson, 1862), A. consobrina (Zetterstedt, 1838), A. mullensis (Cameron, 1883), A. nottoni Ferrer-Suay & Pujade-Villar, 2015 and Phaenoglyphis heterocera (Hartig, 1841). The presence of previously recorded species is confirmed and new records are specified. A key to all Charipinae species ever recorded in Poland is given.

Establishing laboratory cultures and performing ecological and evolutionary experiments with the emerging model speciesChironomus riparius

2019

Chironomus riparius is a well‐established model organism in various fields such as ecotoxicology and ecology, and therefore, environmental preferences, ecological interactions and metabolic traits are well‐studied. With the recent publication of a high‐quality draft genome, as well as different population genetic parameters such as mutation and recombination rate, the species can be used as an alternative to the Drosophila models in experimental population genomics or molecular ecology. To facilitate access to this promising experimental model species for a wider range of researchers, we describe experimental methods to first create and sustain long‐term cultures of C. riparius and then use…

Changes in carbohydrate metabolism in Plasmopara viticola-infected grapevine leaves.

2011

International audience; The oomycete Plasmopara viticola is responsible for downy mildew, a severe grapevine disease. In infected grapevine leaves, we have observed an abnormal starch accumulation at the end of the dark period, suggesting modifications in starch metabolism. Therefore, several complementary approaches, including transcriptomic analyses, measurements of enzyme activities, and sugar quantification, were performed in order to investigate and to understand the effects of P. viticola infection on leaf starch and-to a larger extent-carbohydrate metabolism. Our results indicate that starch accumulation is associated with an increase in ADP-glucose pyrophosphorylase (AGPase) activit…

Linking extreme seasonality and gene expression in arctic marine protists

2021

ABSTRACTAt high latitudes, strong seasonal differences in light availability affect marine organisms and restrict the timing of ecosystem processes. Marine protists are key players in Arctic aquatic ecosystems, yet little is known about their ecological roles over yearly cycles. This is especially true for the dark polar night period, which up until recently was assumed to be devoid of biological activity. A 12 million transcripts catalogue was built from 0.45-10 μm protist assemblages sampled over 13 months in a time series station in an arctic fjord in Svalbard. Community gene expression was correlated with seasonality, with light as the main driving factor. Transcript diversity and evenn…
