Monitoring arthropods diversity in the “Costières de Nîmes” viticulture landscape

Les préoccupations actuelles autour des paysages viticoles vont au-delà des clichés promotionnels développés par les stratégies marketing. En effet, les paysages sont aujourd’hui au cœur d’une demande sociale croissante qui se traduit par différentes lois (la loi paysage de 1993, le paysage reconnu comme patrimoine commun de la nation par la loi n°95-101, la création du Conseil national du paysage par arrêté du 8/12/2000).

The study of wine evolution during barrel aging is an important aspect of wine quality. Our previous works have shown that wine metabolome monitoring by

1H-NMR approaches allows determining the impact of different winemaking processes including traitements using enzymes or finning agents [1].

Nowadays, the entire viticultural and enological process is wisely thought out according to the style of wine to be produced and the local climatic conditions. Acquiring the approach of a technical management route specific for wine production remains a complex learning process for students. To enhance such learning, The Ecole d’Ingénieurs de PURPAN (PURPAN), an engineering school located in Toulouse southwest France, has recently developed Creativini, a collaborative card game in English made of 150 cards spread into 14 batches. Students in groups of 3 to 6 must design a technical production route, from plant material to bottling.

The phenolic profiles of little known red grape cultivars, namely Garnacho, Moribel and Tinto Fragoso, which are autochthonous from the Spanish region of La Mancha (ca. 600,000 ha of vineyards) have been studied over the consecutive seasons of years 2013 and 2014. The study was separately performed over the skins, the pulp and the seeds, and comprised the following phenolic types: anthocyanins, flavonols, hydroxycinnamic acid derivatives (HCADs), total proanthocyanidins (PAs) and their structural features. The selected grape cultivars belong to the Vine Germplasm Bank created in this region in order to preserve the great diversity of genotypes grown in La Mancha.

Context and purpose of the study. Albeit standing as a fashionable research topic dual use of land as viti-voltaic still lacks of fundamental knowledge about whole canopy grapevine response to altered microclimate under panels vs open field conditions.
