Hence, this study aims to examine the phycoremediation capacity of Pb by S. platensis at different levels of salinity. S. platensis was exposed to Pb (4 mg/L) at different levels of salinity (up to 30 ppt) for 12 days. The results indicated that salinity fluctuation was able to reduce phycoremediation capacity of Pb. The highest removal efficiency of Pb was observed in optimum salinity and decreased significantly both in lower and higher salinity treatments. Physiological disturbances in S. platensis were indicated by changes in functional groups and morphology. The morphology of Spirulina platensis both in lower and higher salinity treatments appeared to have changed its shape, resembling a disjointed thread with fading color.]]> Wed 25 Oct 2023 14:58:33 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:15164 Wed 11 Apr 2018 14:25:10 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:2765 Wed 11 Apr 2018 14:22:24 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:12162 Wed 11 Apr 2018 12:17:21 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:21907 Wed 11 Apr 2018 12:08:26 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:46025 Metapenaeus macleayi). These fisheries have experienced declining productivity over the last ten years and increasing occurrence of catchment-derived stressors in estuaries contribute to this problem. We evaluated the effect of pH 4–7.5 on School Prawn survival at two salinities (27 and 14.5), pH 5, 6 and 7.5 on the predation escape response (PER) speed at two salinities (27 and 14.5), and pH 4 and 7.5 on respiration rates. While mortality appeared to be greater in the high salinity treatment, there was no significant relationship between proportional survival and pH for either salinity treatment. Respiration was significantly slower under acidic conditions and the average PER was almost twice as fast at pH 7.5 compared to pH 5 (p < 0.05), indicating prawns may fall prey to predation more easily in acidic conditions. These findings confirm the hypothesised impacts of acidic water on penaeid prawns. Given that the conditions simulated in these experiments reflect those encountered in estuaries, acidic runoff may be contributing to bottlenecks for estuarine species and impacting fisheries productivity.]]> Wed 09 Nov 2022 15:45:04 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:54205 Tue 13 Feb 2024 11:43:46 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:40989 70% for salinity treatments other than the lowest salinity. Survival was 0% in the lowest salinity and all prawns had died within 3 days. Salinity did not appear to impact relative growth across the range of salinities examined. In contrast, relative somatic condition was greater at lower salinities and was negatively correlated with salinity, indicating lower salinities promote enhanced somatic condition in School Prawn. Total fatty acid concentration showed no relationship with salinity or somatic condition index. However, total fatty acid concentration did have a significant positive relationship with total amino acid concentration. Total amino acid concentration showed no linear relationship with salinity or somatic condition index. Quantitative profiling of individual fatty acids and amino acids showed some changes in response to salinity. Alpha-aminoadipic acid showed a significant positive relationship with salinity. These complex patterns suggest several shifts in cellular chemistry may occur throughout the salinity range investigated, potentially with metabolic consequences. These results highlight the complex responses of estuarine crustaceans to changes in salinity.]]> Thu 21 Jul 2022 09:34:25 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:50737 Thu 03 Aug 2023 16:36:36 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:7025 Sat 24 Mar 2018 08:37:55 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:15168 Sat 24 Mar 2018 08:22:38 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:11954 Sat 24 Mar 2018 08:09:41 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:16934 Sat 24 Mar 2018 08:00:30 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:19136 Sat 24 Mar 2018 07:55:55 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:5347 Sat 24 Mar 2018 07:43:52 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:5350 Sat 24 Mar 2018 07:43:52 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:205 Sat 24 Mar 2018 07:43:08 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:273 = 6 ppt NaCl prevented germination.
