COMPARATIVE ANALYSIS OF ADAPTIVE POTENTIAL OF RAPA (RAPANA VENOSA VALLENCIENNES, 1846) AND MUSSELS (MYTILUS GALLOPROVINCIALIS LAMARK, 1819) POPULATIONS FROM ONE BIOTOPE
Journal Title: Вісник Одеського національного університету. Біологія - Year 2014, Vol 19, Issue 2
Abstract
The steadiness of individuals R. venosa and M. galloprovincialis to anhydrous environmental conditions were determined by the duration of their lives. Under the same values of the minimum (two days) and maximum (seven days) of lifetime the specimens of the studied species differed in pace of life. The connection between the stability of molluscs to extreme environmental conditions with their size and weight indicators were shown. For Rapana the maximum of adaptive capacity to the extreme conditions manifested at the level of small-sized and younger individuals, in the case of mussels the large-sized specimens were more stable.
