Seasonal trophic ecology of the invasive crab Percnon gibbesi (Brachyura, Plagusiidae) in the southwestern mediterranean: Insights from stomach contents and stable isotope analyses.

The invasive sally lightfoot crab Percnon gibbesi (H. Milne Edwards, 1853) has spread among the coasts of the Mediterranean Sea, including the coasts of Annaba Gulf (Algeria). Investigating the trophic position of the species and looking for the seasonal variations in the diet of this alien decapod was the aim of this study.

The mussel caging approach in the assessment of trace metal contamination in southern Mediterranean coastal waters: a multi-biomarker study.

In the framework of the biomonitoring programme of the Gulf of Annaba (north-eastern Algeria), this study aims to assess the health status of the Gulf by transplanting the brown mussel Perna perna (Linnaeus 1758) for 12 weeks (June 2017-August 2017) at three sites. The concentrations of copper (Cu), zinc (Zn), lead (Pb) and cadmium (Cd) and as well as a battery of enzymatic and non-enzymatic biomarkers were measured in mussels before and after the transplantation period. Furthermore, analysis of trace metals was performed on the surface layer of the sediment of all the sites.

[Patients’ adaptation strategies for colostomates with a self image disturbance after a month of surgery.].

Background: the establishment of a colostomy is a difficult time for the patient since it undergoes physical, psychological and social changes resulting in the modification of the body self-image. Purpose and Framework : this study aims to identify adaptation strategies for colostomates who have a disturbance of self-image after a month of surgery depending on the Roy Adaptation Model.

Methods: a descriptive quantitative study was realized with a sample of 70 patients with colostomy in the department of surgery Farhat Hached and Sahloul Hospital in Sousse.
