Contribution de l'albumen au développement de la graine chez Medicago truncatula : caractérisation d'un facteur de transcription de type DOF exprimé …
2014
In the current context, which necessitates a reduction in inputs in crop systems and boosting of production of plant proteins to reduce France’s dependency on feed imports,, growing legumes represents an alternative. Grain legumes are major sources of proteins for animal and human nutrition. In the UMR1347 Agroécologie, the objectives of the study group "déterminismes Génétiques et Environnementaux de l’Adaptation des Plantes à des Systèmes de culture Innovants" (GEAPSI) are to promote legume cultivation and adaptation to environmental stresses, via multidisciplinary approaches (genetics, ecophysiology, molecular physiology). This thesis project was carried out in the "Étude des Mécanismes …
Lauksaimniecības marginalizācijas ietekme uz aizsargājamo zālāju saglabāšanos Latvijā
2018
Maģistra darba mērķis - noskaidrot, kāda ir lauksaimniecības marginalizācijas ietekme uz aizsargājamo zālāju saglabāšanos Latvijā. Pētījums aptver visu Latviju. Izmantoti dabisko zālāju izplatības dati uz 2015. gadu un dati par lauksaimniecības zemju apsaimniekošanu 2017.gadā, kā arī augšņu kvalitātes dati. Datu analīze veikta 5 x5 km tīkla šūnā, analīzei izmantojot aprakstošo statistiku (Manna-Vitnija U-tests) un veikta daudzfaktoru regresijas analīze ar Tweedie modeļa datu sadalījumu. 2015.gadā Latvijā aizsargājamie zālāji aizņēma 0,77 % (50 156 ha) no valsts teritorijas. Bieži sastopamie biotopi valstī aizņem lielāko platību - 41 169 ha, bet retie un kompleksie biotopi aizņem, attiecīgi,…
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

MACROLEPIDOPTERA SPECIES WITH VULNERABLE STATUS AND THEIR IMPACT ON THE PROTECTED AREA OF DUMBRAVA SIBIULUI
2013
The present work is a part of a complet study concerning of Macrolepidoptera from the forest “Dumbrava Sibiului” in the Sibiu county. They are presented only the species found by myself for the frist time from this area. I mention that these species were not found by me in the five collections of Lepidoptetra studied by me and preserved at the Natural Hystory Museum in Sibiu.
The “genetic erosion” of the soil ecosystem
2013
Abstract This paper takes into consideration the influence of human activities on the loss of pedodiversity in a Mediterranean area due to large scale farming. In particular it examines the quantitative and qualitative soil changes in a period of 53 years (from 1955 to 2008) evaluating the loss of soil diversity at soil subgroups level of the USDA Soil Taxonomy system. The following indices were used: richness; Shannon’s diversity index; Simpson diversity index; Shannon’s evenness index; Simpson’s evenness index. In this case study, considering what we observed in time, the human intervention in soil transformation could increase the diversity in the landscape in an initial phase, but forwa…
