The family Flabelligeridae was previously represented in Tunisia by four genera including species: Bradabyssa villosa (Rathke, 1843), Therochaeta flabellata (M. Sars G.O. Sars, 1872), Pherusa plumosa (Müller, 1776), and Piromis eruca (Claparède, 1869). In this paper we report a fifth genus, Trophoniella, for the first time Tunisia. specimens were collected Radés Station, Gulf of Tunis (Central Mediterranean) belong to new species, namely Trophoniella radesiensis n. sp., which is...
The occurrences of non-indigenous marine molluscs in Tunisia are reviewed, based booth on a literature survey and original material. Species accepted as established if there two independent reports, either geographically separate or at least one month apart time. On these grounds, 14 species (12 alien 2 expanding their range from elsewhere the Mediterranean), 3 aliens need confirmation but likely to meet standards for acceptation short future, 5 records rebutted questioned. Two more may be...
The molluscan assemblage inhabiting the photophilous algae from artificial rocky shores in theBay of Tunis) was studied February 2009 to 2010. Five monthly replicates were taken with a quadrat 25 × cm .. A total 16105 individuals molluscs, belonging 93 species, collected. Gastropods most species-rich group, 66 species (70.96%), followed by bivalves 26 (27.95%). also abundant 11529 (71.60%), 4575 (28.41%). Nevertheless,Mytilaster minimus dominant overall during period (15.6% abundance),...
Soft bottom molluscan assemblages from the Bay of Tunis have been studied in order to analyse their seasonality and trophic diversity relation environmental variables. A total 147 species molluscs was identified, with gastropods displaying highest richness bivalves abundances, including five non-indigenous such as dominant ectoparasite Polycerella emertoni. Carnivorous scavenger were among most frequent species, reflecting a diverse benthic community. Seasonal changes significant, being more...
A study on the decapod assemblage inhabiting a shallow meadow of Cymodocea nodosa from bay La Goulette (Tunisia) was carried February 2009 to 2010. Monthly samples (with replicates) were taken in morning and at night, with small Agassiz trawl. In total 11699 specimens belonging 41 species caught. Significant day-night seasonal changes are mainly related movements (feeding) recruitments. Higher abundance richness reported night. Analyses rendered no significant relationships between plant...
The cardid bivalve Acanthocardia tuberculata is harvested in southern Spain and on the Atlantic coast of Morocco for Spanish canning industry. reproductive cycle population structure this species were studied from June 1999 to May 2000, using histology condition indices, as well modal size classes length-frequency distribution analysis. samples collected monthly during autumn winter months fortnightly spring summer months. A total 4,047 specimens examined, which 3,539 processed biomass...
The present study used two mitochondrial markers (16S rRNA and COI) to assess the genetic diversity of a newly founded Lessepsian migrant mussel, Brachidontes pharaonis, in Tunisian waters. species appears be restricted only one population Rades Harbour, northern part country. Phylogenetic analyses revealed monophyly B. pharaonis Tunisia. Both molecular high variability population. Haplotype networks demographic confirmed recent expansion events within this Multiple human-mediated...
Sea bottom sampling of the Skerki Bank in Strait Sicily updates census marine molluscs inhabiting a biogeographically key sector Mediterranean Basin. One single dredge haul at 112-m depth yielded 110 molluscan species belonging to Gastropoda, Bivalvia, and Scaphopoda, which 41 are new records for Tunisian jurisdictional waters, including three gastropod science. Nearly all shared with fauna adjacent Italian most them reported also from Malta. We stress that sites characterized by relevant...
Our study aimed to evaluate the effect of trace element pollution in polychaete Perinereis cultrifera (Grube, 1840) from two Tunisian coasts (the port Rades, S1; and Punic Carthage, S2). To this end, we used an approach based on proximate composition, biomarker responses bioaccumulation. results showed a decreasing order metals concentrations (Zn>Cu>Cd>Pb) P. S1 S2. The accumulation Cd, Cu Zn was significantly higher than S2, especially summer. Lipid, protein glycogen content also...
