El pòlip de Trembley: L'"animal-planta" que va sacsejar la biologia del segle XVIII
2013
Els experiments d’Abraham Trembley amb l’hidra d’aigua dolça no només van sorprendre els seus contemporanis per la seva espectacularitat, sinó que els seus resultats també van causar un enorme trasbals en la comunitat científica del seu temps. Idees com la «cadena del ser», el mecanisme de generació dels éssers vius o la mateixa naturalesa de l’ànima van ser fortament sacsejades.

Les Gaulois d’Île-de-France au second âge du Fer et leur cheptel : état de la question
2005
During the last twenty years, under the impetus of Patrice Méniel, the number of archaeozoological studies of Iron Age sites in the Ile de France region has greatly increased. Even though there are still certain blanks, we can make a first assessment of the results already obtained.
Genetic variability at αs2-casein gene in Girgentana dairy goat breed
2014
Casein genes are highly polymorphic and the high degree of variability has qualitative and quantitative effects on milk composition thereby affecting chemical, physical and technological properties of goat milk. The aim of this work was to evaluate the genetic polymorphisms of the αs2-casein (CSN1S2) gene in the endangered Girgentana dairy goat breed in order to assess the genotypes distribution, as it is known genotype influences technological and nutritional milk properties. The study was performed on 207 sample of Girgentana goat breed, analysed with different PCR protocols. The most frequent alleles was A (0.722), followed by F (0.225), C (0.051) and E (0.002) while B, D and 0 alleles w…
The Use of Stable Isotope Ratio Analysis to Trace European Sea Bass (D. labrax) Originating from Different Farming Systems
2020
This study aimed to determine whether isotopic ratio mass spectrometry (IRMS) can discriminate farmed European sea bass according to different farming systems and geographic origins. Dicentrarchus labrax of commercial size from three different rearing systems (concrete tank inland, sea cages, and extensive methods in valleys or salt works) were collected at the trading period (autumn&ndash
