Phylogenetic relationships among tetraploid species of Bellevalia (Asparagaceae) endemic to south-central Mediterranean

2017

AbstractIn the south-central Mediterranean four tetraploid species of Bellevalia occur: B. dolichophylla, B. galitensis, B. mauritanica, and B. pelagica. Another group of plants, morphologically similar to B. dolichophylla, has been recently recovered in Zembra Island (Tunisia). A phylogenetic reconstruction involving all these tetraploid taxa was performed using both plastidial and nuclear markers (trnL-trnF and ITS, respectively). For all these taxa, an allopolyploid origin involving B. romana and B. dubia is supported. Regarding plants from Zembra, they may fall within the variability of B. dolichophylla.

A preliminary check list of macromycetes in northern Tunisia

2016

AbstractWithin the last decade, checklists of fungi of several countries have been published or updated. Nevertheless, no checklists of macromycetes have hitherto been published for Tunisia (North Africa) apart from a mycocoenological study reporting 34 listed species. This work presents a list of macromycetes collected from January 2014 to March 2015 in six governorates of northern Tunisia. One hundred and twenty-three species (117 basidiomycetes and six ascomycetes) belonging to 78 genera and 46 families were recorded.

Nuove ricerche tuniso-italiane al teatro romano di Althiburos

2017

Il progetto di rilievo, scavo, studio e valorizzazione del teatro romano di Althiburos (El M’deïna, Tunisia) vede coinvolti l’Institut National du Patrimoine, l’Università di Macerata ed il Politecnico di Bari. Nelle tre campagne sinora svolte è stato iniziato il programma di rilievo del monumento e catalogo degli elementi architettonici e sono stati iniziati alcuni saggi stratigrafici che hanno permesso di indagare le fasi più tarde della vita dell’edificio, da quando cioè, in età bizantina, il teatro venne trasformato in fortezza sino all’età moderna. Il progetto della missione congiunta tuniso-italiana prevede di riprendere quest’anno lo studio del monumento e del materiale già scavato e…

Les commissions coloniales rattachées au Comité des Travaux historiques et scientifiques

2000

The colonial Commissions connected to the Comité des travaux historiques et scientifiques. In the late nineteenth century, the Comité des travaux historiques et scientifiques became a bigger and bigger research organization, always closely linked to the successive political governments. With each new French conquest, a commission of parisian scientists and local correspondents was created and attached to it, as in 1864, the scientific commission for Mexico, in 1884, the commission for Tunisia, in 1908, the archeological commission for Indochina. The example studied here is that of the commssion for Tunisia, which coordonated researches in archeology and epigraphy in North Africa, thanks to …

Crocidura cossyrensis Contoli, 1989 (Mammalia, Soricidae): karyotype, biochemical genetics and hybridization experiments

2004

The shrew Crocidura cossyrensis Contoli, 1989 from Pantelleria (I), a Mediterranean island 100 km south of Sicily and 70 km west from Tunisia, was investigated in order to understand its origin and its relationship with C. russula from Tunisia, Morocco and Switzerland. With the exception of a single heterozygote centric fusion, C. cossyrensis had a karyotype identical with that of C. russula from Tunisia (2N = 42, NF = 70 to 72), but it differed from C. russula from Morocco and Switzerland (2N = 42, NF = 60). The former have 5-6 pairs of chromosomes with small arms that are acrocentric in the latter. Genetic comparisons with allozyme data revealed small genetic distance (0.04) between C. co…

Genetic structure of Tunisian sheep breeds as inferred from genome-wide SNP markers

2020

Abstract Assessing the status of genetic variability of native sheep breeds could provide important clues for research and policy makers to devise better strategies for the conservation and management of genetic resources. In this study, a genetic investigation of Tunisian sheep breeds using a genome-wide scan of approximately 50,000 SNPs was performed. To reconstruct genetic structure and relationships among four sheep breeds, 40 samples belonging to fat-tailed Barbarine, Queue Fine de l’Ouest, Noire de Thibar and D’Man breeds were genotyped using Illumina Ovine SNP50 BeadChip. Tunisian breeds averaged 96 % polymorphic loci with an expected heterozygosity (He = 0.36). Genetic analysis of r…

Bryophytes collected during the 12th “Iter Mediterraneum” (Tunisia, 24 March – 4 April, 2014). First contribution

2015

Part of the bryophytes collected during Iter Mediterraneum XII is listed. Some noteworthy species were found: Dicranella howei, had so far been recorded only doubtfully from Tunisia; Funaria hygrometrica, Grimmia laevigata, Grimmia trichophylla, Imbribryum alpinum, Pogonatum nanum, Rhynchostegium riparioides, Scleropodium touretii, Scorpiurium circinatum, Thamnobryum alopecurum, Timmiella barbuloides, Tortella squarrosa, Tortula muralis and Tortula vahliana, had not been reported from that country for more than half a century.

Cultivation of some mushrooms species originating from Tunisia and exploration of their valuable metabolites

2017

Mushrooms present interests for consumption as food, as traditional medicine or in bioremediation, due to their nutritional, antioxidant, antimicrobial, therapeutic and enzymatic values. The valorisation of indigenous species of mushrooms requires well characterized collections. Although macrofungi are widespread in Tunisian forests, their diversity and ecology remain generally underexplored which hindered their exploitation. In particular, the in vitro cultivation of the mycelial form could have many advantages: (a) it offers faster growth rates which may have industrial and biotechnological benefits, and (b) will allow better resource management (longer conservation of active forms) and g…
