Complexity is increasingly the hallmark in environmental management practices of sandy shorelines. This arises primarily from meeting growing public demands (e.g., real estate, recreation) whilst reconciling economic demands with expectations of coastal users who have modern conservation ethics. Ideally, shoreline management is underpinned by empirical(More)
Within the framework of the MEDCORE project on the ecology and management of Mediterranean coastal areas we decided to include the local dissemination of scientific results in Tunisia. The involvement of a local public school, and the joint work of local teachers and of local and international researchers, was chosen as a dissemination method because of the(More)
Tourism has long been considered as a 'clean industry' with almost no negative effects on the environment. This study demonstrated, in two different coastal systems (Mediterranean and Baltic), that tourism related activities are particularly affecting the sandy beach meio- and nematofauna in the upper beach zone, the specific ecotone in which many meiofauna(More)
The role of development in current neo-Darwinian evolutionary theory is still underestimated. Only a few experimental and theoretical efforts have been made to bridge the gap, among which the theories of genetic assimilation, stabilising selection and autopoiesis. The relationship between the organism and its environment is a focal point for understanding(More)
a r t i c l e i n f o Ghar El Melh is a shallow lagoon (average depth of 0.8 m) that has undergone a eutrophication process due to growing human pressures. To obtain a global frame of the ecosystem functioning, an optical and an ecological classification were used in parallel. Downwelling and upwelling spectral irradiances were measured in situ in 22(More)
The analysis of animal movements may help to understand orientation strategies. While there have been many studies on sandhoppers' orientation mechanisms through the analysis of their orientation angles, no attempts have been made to analyze individual tracks under (varying) natural conditions. The species Talitrus saltator (Montagu, 1808) has the ability(More)
The expression of biological rhythms was investigated in five populations of three different species of talitrid amphipods from various habitats in the Maremma Regional Park, Grosseto, Italy: Talitrus saltator (from a sandy beach and a canal), Orchestia montagui (form a Posidonia banquette), and O. gammarellus (from a cave entrance and a river bank).(More)
