| Проанализировано распределения бактерио-, мейо- и макрозообентоса в зависимости от физико-химических характеристик донных осадков бухты Южная (г. Севастополь, Чёрное море). Содержание нефтяных углеводородов составляло 607,2 – 1458,0 мг/100 г сух. осадка. В вершинной части бухты отмечено снижение концентраций нефтяных углеводородов. Общая численность гетеротрофных бактерий находилась в пределах 104 кл./г, плотность мейобентосного населения 9500 – 197800 экз./м2. Наибольшая средняя плотность мейобентоса приурочена к кутовой части бухты. Соотношение основных групп мейобентоса указывает на более благоприятные условия для существования мейобентосных организмов в вершине бухты. В составе макрозообентоса отмечен 31 таксон. Численность макрозообентоса не превышает... |

| The survey of sediment and hydrological parameters in the old harbor of Bizerte has revealed that this ecosystem knows a high anthropogenic pressure. In this area waters were characterized by weak contents in dissolved oxygen and sediments, rich in fine fraction, were loaded in hydrocarbons and in organic matter. The free-living nematodes, predominant taxa, responded to these disturbances by a significant decrease in their densities and their biomasses and had tendency, notably at the most isolated sites, to penetrate deeply to escape surface sediments highly loaded in hydrocarbons and in organic matter. |

| Durante los veranos australes de 1995-1996 y 1997-1998 se llevó a cabo, en Ensenada Guayaquil, cuerpo de agua aledaño a Punta Fort William, Isla Greenwich, del archipiélago de las Shetland del Sur, lugar del asentamiento de la Estación Científica "Pedro Vicente Maldonado", estudios químicos de la calidad de las aguas tendientes a determinar el eventual impacto que las actividades humanas pudieran ocasionar sobre tal ecosistema. Se presenta información acerca de las condiciones de oxigenación de las aguas, temperatura y salinidad de las mismas, la capacidad nutricia en relación con la concentración de micronutrientes inorgánicos así como información acerca de la presencia de hidrocarburos del petróleo disueltos y dispersos y, para establecer la efectividad... |

| Using Using SCUBA diving, surveying the coral reef communities at four sites, Red Sea Egypt was done. These sites are: Ras El Behar (polluted by petroleum oil), El-Hamraween (impacted by phosphate shipping), Shabrour Umm Gam’ar (harmed by recreational activities and has been suffering from the outbreak of Acanthaster planci during 1998) and Kalawy (a control site). The skeletal growth of the coral Stylophora pistillata was promoted greatly at the expense of other corals, in presence of chronic oil pollution (Ras El-Behar). In contrast, this species was completely suppressed in presence of phosphate and sulphur enrichment. Petroleum oil led to coral scarcity, space monopolization by one coral and increased sea urchins and algae. Coral reefs enriched with... |
