Amélioration de la qualité nutritionnelle des aliments de consommation courante
2017
Les pays développés sont confrontés à des pathologies liées à une consommation excessive de sel, de matières grasses et de sucres. Cependant, ces ingrédients influencent non seulement la qualité nutritionnelle des aliments, mais aussi leurs propriétés sensorielles et leur durée de conservation. Ainsi, le principal défi consiste à formuler des aliments plus sains et acceptables pour les consommateurs. Dans ce contexte, le projet TeRiFiQ a développé différentes stratégies pour obtenir des réductions binaire significatives des teneurs en sel - matières grasses et en sucre - matières grasses des produits alimentaires consommés fréquemment en Europe, tout en garantissant les qualités nutritionne…
Conservation of traditional rural biotopes in Finland : a social-ecological approach
2018
This research focuses on conservation of traditional rural biotopes, which are biodiverse meadows and wood-pastures that are dependent on management through grazing or mowing. These low-intensity management actions have become rare as a result of agricultural modernisation. I have utilised a social-ecological approach in order to seek for the most critical factors hindering conservation of traditional rural biotopes in Finland. I also explore practical solutions that have the potential to improve their conservation status. The coverage of traditional rural biotopes has faced severe habitat loss during the last 150 years. This has led to endangerment of several habitat types and species that…
Database Species-Area Relationships in Palaearctic Grasslands
2012
The Database Species-Area Relationships in Palaearctic Grasslands (GIVD ID EU-00-003) is an initiative of the European Dry Grassland Group (EDGG) and primarily functions as repository for all data sampled during the EDGG Research Expeditions. During these expeditions two types of highly standardised sampling of dry grassland vegetation in the Palaearctic realm are carried out: (i) nested-plot sampling on squares of 0.0001, 0.001, 0.01, 0.1, 1, 10, and 100 m2; (ii) additional normal releves of 10-m2 plots. For all plot sizes, the terricolous vascular plants, bryophytes, and lichens are recorded that are superficially present (shoot presence). Additionally, for all 10-m2 plots species cover i…
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,…
