The distribution of some heavy metals in three different organs of mullet, Liza abu, and catfish, Silurus triostegus, from Atatürk Dam Lake located on Euphrates (Turkey) was studied. Co and Mo concentrations were below limits of detection in all fish organs, whereas Ni was also below limits in organs of mullet. The metal accumulation in the liver and gill of L. abu and S. triostegus was found t...

This study aimed to determine the impact of three abiotic factors (Temperature, pH, and salinity) on metabolic activities (macromolecules) germination rate Acinos alpinus subsp. Meridionalis (Satureja) seeds. In vitro, seed tests were performed in an aqueous medium. They monitored as a function time at different levels temperature, NaCl concentration, pH. The best (85.3%) was achieved 15 °C pH ...

New Zealand Journal of Ecology (1997) 21(2): 141-152 ©New Zealand Ecological Society spp.), and rats (Rattus spp.), may also be contributing to the decline of kaka by reducing the birds’ productivity (Beggs and Wilson, 1991). A significant competitive interaction with possums is suggested by the fact that kaka remain common in the South Island only where possum densities are relatively low (O’D...
