title: ОЦЕНКА ВИДОВОГО БОГАТСТВА РАЗЛИЧНЫХ ГРУПП БЕНТОСА ПРИ РАЗНЫХ УРОВНЯХ ЗАГРЯЗНЕНИЯ БИОТОПОВ И УСИЛИЯХ ПРОБООТБОРА
abstract: The peculiarities of species richness structure and species-accumulation curves for benthic diatoms and zoobenthos assemblages had been comparatively analyzed in relation to different level of sediment pollution. Analysis was based on the same grid of samples collected at 7 near shore locations of South–West Crimea. Evaluation of optimal ratio between minimal sampling efforts and maximal information about zoobenthos and benthic diatom species richness at the variously polluted sampling locations
