Changing Plant-based Subsistence Practices among Early and Middle Holocene Communities in Eastern Maghreb
2020
The eastern Maghreb is a key area for understanding environmental and cultural dynamics during the early and middle Holocene. Capsian populations from around 10000–7500 cal BP were among the last foragers in the region. Capsian sites are known as escargotières (land shell middens), and locally called rammadiyat (meaning ashy mound). As taphonomic conditions in Capsian open-air sites generally favour the preservation of resistant materials such as shells and bones rather than fragile plant remains, this study integrates macro-botanical and microfossil evidence from phytoliths, calcitic wood ash pseudomorphs and dung spherulites, since each is influenced by different formation and post-deposi…
Agronomical and postharvest evaluation of the essential oils of Sicilian rosemary (Rosmarinus officinalis L.) biotypes
2019
Rosmarinus officinalis L. is an aromatic shrub commonly found in the Mediterranean area. It is used in cooking both to add aroma and as a preservative in processed foods. Essential oils of rosemary are used in medicine and in the cosmetics industry due to their considerable biological properties. The yield and quality of rosemary essential oils mainly depend upon the chemo type, environmental conditions and cultivation techniques. The aim of this study was to evaluate the qualitative and quantitative characteristics of essential oils of wild R. officinalis biotypes found in Sicily using different drying methods. Five types of drying methods were used for the tests: a) shade drying under a r…
CONTRIBUTION TO THE KNOWLEDGE OF THE TRADITIONAL USES OF NATIVE PLANTS IN SICILY
2016
The Sicilian territory as a whole presents orographic, geopedological, hydrographic characters and climate conditions that determine a wide diversity of environments that host a rich vascular flora consisting of over 3250 specific and intraspecific taxa (subspecies, varieties and forms), belonging to 880 genera of 134 botanical families (1). Of the above mentioned flora, about 500 entities are endemic and in several cases their populations are constituted by a small number of individuals and / or distributed on limited areas. Within this great biodiversity, which places Sicily among the regions with greater floristic diversity of both Italy and the Mediterranean area, it is noteworthy that …
CITES konvencijas noteikumu pārkāpumu izpēte starptautiskajā lidostā “Rīga”
2017
Maģistra darba mērķis ir izanalizēt CITES konvencijas pārkāpumus starptautiskajā lidostā „Rīga” un visā Latvijas teritorijā, to cēloņus, izstrādāt ieteikumus un risinājumus šo pārkāpumu novēršanai. Darbā analizēti autores veikto aptauju rezultāti, intervējot ielidojošos pasažierus starptautiskajā lidostā „Rīga” no Eiropas Savienības un trešajām valstīm par attieksmi pret CITES konvenciju, noskaidrojot informētības līmeni un informācijas avotus. Izanalizēta CITES konvencijas pārkāpumu skaita dinamika lidostā „Rīga” periodā no 2011.-2015.gadam. Maģistra darbs sastāv no 66 lapaspusēm. Darbs satur 23 attēlus, 3 tabulas, 54 izmantotos literatūras avotus un 1 pielikumu.
Study of quantitative and qualitative variations in essential oils of Sicilian oregano biotypes
2015
Essential oil (EO) was extracted using hydrodistillation from samples of Origanum vulgare subspecies hirtum (Link) Ietswaart, gathered from the wild in various parts of Sicily, Italy; GC-FID and GC-MS analyses were subsequently performed. The aim of the study was to analyze the relationship between essential oil yields and the geographical distribution of oregano wild populations based on variations in environmental factors as collection sites. Moreover, the purpose was to group Origanum vulgare subspecies hirtum biotypes according to the chemical composition of the EO. The seven principal components in the EO was thymol (24.0–54.4%), γ-terpinene (9.8–30.5%), ρ-cymene (5.2–18.7%), α-terpine…
