FIRST RECORD IN TUNISIA OF CLOSTEROCERUS CHAMAELEON (GIRAULT) PARASITOID OF THE EUCALYPTUS GALLWASP OPHELIMUS MASKELLI (ASHMEAD) (Hymenoptera Eulophi…

2010

Closterocerus chamaeleon (Girault) (Hymenoptera Eulophidae), parasitoid of the Eucalyptus gall wasp Ophelimus maskelli (Ashmead) (Hymenoptera Eulophidae) has been recorded for the first time in Tunisia in July 2007. This record suggests that 14 months after its release in Sicily, in May 2006, it has spread over Sicily Channel.

First Record of Leptocybe invasa and Ophelimus maskelli Eucalyptus Gall Wasps in Tunisia

2010

Two Australian gall wasps were detected for the first time in Tunisia on the foliage of Eucalyptus camaldulensis trees. Leptocybe invasa was detected in 2004, while Ophelimus maskelli in 2006. L. invasa makes galls on petioles, leaf midribs and young branches whereas O. maskelli induces galls on limbs. Vigilance is recommended when seedlings are carried to plantation.

Checklist of the vascular plants collected during the 12th “Iter Mediterraneum” in Tunisia, 24 March – 4 April 2014

2015

The vascular plants (plus one alga) collected during Iter Mediterraneum XII of OPTIMA in North Tunisia have been studied. In all, 1374 gatherings were made from 43 localities in the “Cap Bon” region, “Dorsale Tunisienne”, “Tunisie du Nord-Est”, “Vallée de la Medjedah”, “Mogods” and “Kroumirie” areas. They belong to 82 families and 539 species or subspecies. Three taxa are new for the flora of Tunisia (Cerastium diffusum subsp. gussonei, Senecio leucanthemifolius subsp. mauritanicus, and Ulmus minor subsp. canescens), 7 represent new records for the “Kroumirie”, 15 for the “Mogods”, 3 for the “Tunisie du Nord-Est”, 2 for the “Dorsale Tunisienne”, and 8 for “Cap Bon”

Hyacinthoides kroumiriensis sp.nov. (Hyacinthaceae): a new species from North West of Tunisia

2014

Hyacinthoides kroumiriensis El Mokni, Domina, Sebei& El Aouni, a new species in Hyacinthaceae from Kroumiria region, North West of Tunisia, is described and illustrated. Morphological characteristics with illustrations, habitat and description of the new species are provided, in addition to a diagnostic comparison with one phenotypically similar species within the same clade.

Macromycetes' diversity in Tunisia

2017

In Tunisia, about 12% of the country area is covered by forests which have favorable climatic factors likely to harbor a high macrofungal biodiversity. However, this valuable bioresource remains understudied especially regarding their distribution, ecology, abundance and diversity. The initiation of the first national inventory of macrofungi in NorthWestern Tunisian forests was published by our group in 2016. The study covered six governorates, sixty seven sites and enabled the identification of one hundred and twenty-three specimens. Abiotic environmental factors such (as bioclimatic stage, rainfall and edaphic conditions) and biotic factors (plant association and nature and density of the…

Suivi Botanique de l’Archipel de Zembra

2013

Une mission scientifique a été réalisée sur l’archipel de Zembra du 9 au 15 Mai 2013. Les principaux objectifs fixés pour cette mission étaient les suivant: - améliorer les connaissances générales de la flore et de la végétation sur l’archipel, - réaliser un nouvel inventaire de la végétation à partir des placettes délimitées suite à la dératisation de 2010 sur Zembretta afin d’évaluer le sens d’évolution de la végétation, - le suivi de la végétation sur ces placettes, réalisé dans le cadre des ″Iles Sentinelles en Méditerranée″ dont l’archipel de Zembra en fait partie, - améliorer la connaissance des groupements végétaux et des habitats de l’île tout en prenant en compte les habitats favor…

The florula of hypersaline habitats in Central Mediterranean and its biological traits

2018

Salinity is one of the most widespread soil degradation processes. In fact in saline soils uneven temporal and spatial water distribution and localized high concentration of salts occur, characterizing restricted habitats where most of the present organisms are halophilic or salt tolerant. Soils could be classified hypersaline when salt concentration exceeds certain thresholds (1, 2). For this study were analysed 10 hypersaline soil localities from Sicily (Birgi, Isola Lunga, Salinelle Marsala, Capo Feto, Piana del Signore, Vendicari) and Tunisia (Qurba, Khniss, Ras Dimas, Chebba). These areas are temporarily flooded in autumn and winter, with longer permanence of water in some zones. Salt …
