| The effects of anthropogenic particulate emissions from ships on the radiative, microphysical, and chemical properties of m(oderately polluted marine stratiform clouds are examined. A case study of two ships in the same air mass is presented where one of the vessels caused a discernible ship track while the other did not. <i>In situ</i> measurements of cloud droplet size distributions, liquid water content, and cloud radiative properties, as well as aerosol size distributions (outside cloud, interstitial, and cloud droplet residual particles) and aerosol chemistry, are presented. These are related to measurements of cloud radiative properties. The differences between the aerosol in the two ship plumes are discussed; these indicate that... |

| The Godineau Swamp is home to several species of plants, wildlife, fish and waterfowl, including our protected Scarlet Ibis. It has been heavily influenced by anthropogenic activities and probably needs careful regulation of its development in order to obtain the maximum benefits from the swamp without destroying it. The Fisheries component of the Godineau Swamp Research Project aims to document the fish species that live in the swamp, their relative distribution and abundance and characterize the fishing practices in the area. The first phase has been completed and the second phase, characterisation of the fishing practices, is carded to begin in mid- November. The whole Godineau Research project is directed at assessing the ecology of the swamp in its... |

| The answer of the free nematode populations to the physico - chemical state of “ lake ” south Tunis has been studied in autumn 96 from 10 sampling sites. Their very weak specific diversity (Hermi, 2001) and the non selective détritivorous proliferation (1B) bound to the strong contents in recorded organic matter (Hermi, 2001) revealed the sensitivity of nematodes to the eutrophication and nutritionnal pollution. According to several interrelationships calculations, the waters saturation in oxygen, their contents in abeyance matter and in nitrogen as well as the sediments granulometry and their contents in certain heavy metals, appeared the most lagoonar determining parameters. Otherwise, the answer of nematofaunistic communities living in South lake was... |
