Effects of N and P supply on phytoplankton in Bizerte Lagoon (western Mediterranean)
Abstract Enriched bottle experiments were conducted in situ during winter (January and February) and summer (July and August) 2001 to examine the effects of nutrient enrichments (+ N, + P and + NP)Expand

BLOOMS OF THE DIATOM GENUS PSEUDO-NITZSCHIA H. PERAGALLO IN BIZERTE LAGOON (TUNISIA, SW MEDITERRANEAN)
The phytoplankton composition, including the potentially toxic diatom genus Pseudo-nitzschia, and related physico-chemical water properties were determined at four stations in Bizerte Lagoon (SWExpand

Consequences of contaminant mixture on the dynamics and functional diversity of bacterioplankton in a southwestern Mediterranean coastal ecosystem.
Contamination of coastal environments is often due to a complex mixture of pollutants, sometimes in trace levels, that may have significant effects on diversity and function of organisms. The aim ofExpand

Toxicity of benz(a)anthracene and fluoranthene to marine phytoplankton in culture: does cell size really matter?
The toxicity of benz(a)anthracene and fluoranthene (polycyclic aromatic hydrocarbons, PAHs) was evaluated on seven species of marine algae in culture belonging to pico-, nano-, andExpand
