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 ]]> Coastal wetlands can be saved from sea level rise by recreating past tidal regimes https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:38275 Wed 08 Jun 2022 18:55:40 AEST ]]> Hydrogeochemical and ecological risk assessments of trace elements in the coastal surface water of the southern Caspian Sea https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:39746 Fe (73.6) > Zn (67.8) > Mn (29.9) > Cu (5.7) > Mo (3.7) > Cd (2.8) > Se (2.3) > V (1.9) > Co = As (1.8) > Sb (1.2) > Pb (0.6). TEs displayed high variations within samples, reflecting many sources that control their concentrations in the coastal water. Most TEs displayed elevated concentrations in the east and west of the study area. The Na-Cl water type in the majority of investigated sites indicates excess alkaline elements and strong acid anions relative to alkaline earth cations and weak acid anions. Considering the saturation states of minerals, carbonate and evaporite minerals are oversaturated and unsaturated in surface water, respectively. Compositional interrelations between aqueous species showed that reverse cation exchange may have occurred. The excess SO42− content, derived from irrigation return flow and domestic greywater, probably plays a crucial role in the mobilization and transport of Zn and Pb by binding to sulfate ligands and forming aqueous complexes. Ecological risk assessment of TEs revealed that water in the majority of sites is safe in terms of As, Se, Pb, and Cd content, and unsuitable with respect to Zn and Cu. Acute and chronic toxicities of Cu and Zn are reported in several sites, thus coastal water cannot be used for fishery and protecting “nature reserve” purposes. However, industrial activity and tourism are safe to be conducted in most coastal water sites.]]> Wed 07 Feb 2024 15:26:27 AEDT ]]> Efficient plastic recycling and remolding circular economy using the technology of trust–blockchain https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:48629 Wed 07 Feb 2024 15:26:20 AEDT ]]> COVID pollution: impact of COVID-19 pandemic on global plastic waste footprint https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:38282 Wed 07 Feb 2024 15:23:00 AEDT ]]> Severe tropical cyclones over southwest Pacific Islands: economic impacts and implications for disaster risk management https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:51002 Wed 07 Feb 2024 15:02:59 AEDT ]]> From environmental impact assessment to strategic environmental assessment in Bangladesh: Evolution, perspective, governance and challenges https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:51927 Wed 07 Feb 2024 15:00:03 AEDT ]]> Blue carbon ecosystem monitoring using remote sensing reveals wetland restoration pathways https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:51517 90% accuracy at 0.1 m resolution.

Saltmarsh growth patterns were species-specific, influenced by species’ reproductive and dispersal strategies. Our findings suggested that biotic factors and interactions were important in influencing species’ distributions and succession trajectories. This work can help improve the efficiency and effectiveness of restoration planning and monitoring at coastal wetlands and similar ecosystems worldwide, with the potential to apply this approach to other types of remote sensing imagery and to calculate other rehabilitation co-benefits.

<i>Cochlodinium geminatum</i> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:42864 Cochlodinium geminatum were first recorded as new, harmful algal bloom (HAB)-forming dinoflagellate, in the Pearl River Estuary, China. Previous studies indicated that allelopathy (the release of chemical compounds) is an important competitive strategy for C. geminatum in inhibiting the growth of phytoplankton competitors, however, little is known about the allelochemicals produced by this species. In this study, allelopathic compounds were characterized using a series of chromatographic techniques. Methanol extracts from cultures showed significant inhibitory effects towards the co-occurring phytoplankton, Akashiwo sanguinea, and potent hemolytic activity against rabbit erythrocytes. Solid phase extraction (SPE) fractions from a reverse phase SPE column, exhibited inhibitory and synergistic effects on A. sanguinea growth, of which fractions eluted in 80% and 100% methanol showed the strongest allelopathic activity. These fractions were further purified using reverse phase high performance liquid chromatography (HPLC), and six fractions were collected. Three fractions displayed strong inhibitory effects towards A. sanguinea, with 14%-25% inhibitory rates, but a higher 35% inhibitory rate was observed when fractions were combined, suggesting allelochemicals had synergistic allelopathic effects. Allelopathic activity also exhibited time dependent reduction when stored at -20℃. Furthermore, trypsin digestion and dialysis assays indicated C. geminatum produced multiple allelopathic compounds. Our study demonstrated that species of C. geminatum produced and released multiple allelopathic compounds of low polarity and sufficient hydrophilicity, which elicit important competitive advantages by inhibiting co-occurring phytoplankton, and promoting population growth.]]> Tue 06 Sep 2022 09:52:23 AEST ]]> Assessing the effects of sediment and tidal level variability on coastal wetland evolution https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:51440 Tue 05 Sep 2023 17:57:09 AEST ]]> The influence of large-scale climate modes on tropical cyclone tracks in the southwest Pacific https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:53550 Tue 05 Dec 2023 10:18:02 AEDT ]]> Comparative genomics for understanding intraspecific diversity: a case study of the cyanobacterium Raphidiopsis raciborskii https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:50677 Tue 01 Aug 2023 15:19:25 AEST ]]> Kinetics, isotherms and adsorption–Desorption behavior of phosphorus from aqueous solution using zirconium–iron and iron modified biosolid biochars https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:45345 −1 for 24 h by Zr–FeBC and Fe-BC at pH 5 and 4, respectively. Desorption studies were performed to investigate the reusability, cost-effectiveness and stability of the adsorbents Zr–FeBC and Fe-BC. The adsorption–desorption study suggests that both examined biochars have considerable potentiality as adsorbent candidates in removing as well as recovery of P from wastewaters. Results also reveal that the regenerated Zr–FeBC and Fe–BC could be utilized repetitively in seven adsorption–desorption cycles using NaOH as a desorbing agent, which greatly reduces the P-removal cost from wastewaters. Thus, P enriched biochar could potentially be used as fertilizer in the agriculture sector.]]> Thu 27 Oct 2022 15:20:47 AEDT ]]> Commercial marine fish species from Weh Island, Indonesia: Checklist, distribution pattern and conservation status https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:44826 Thu 27 Oct 2022 12:26:05 AEDT ]]> Trophic Structure of Temperate Australian Oyster Reefs Within the Estuarine Seascape: a Stable Isotope Analysis https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:50494 40% contribution) for three resident and five transient species, including polychaetes, blue swimmer crabs, toadfish, luderick, leatherjackets, oyster gobies, and stingarees.

However, GC x GC resolved seven times more BVOCs than GC–MS (290 vs. 40), with a higher proportion of compounds tentatively identified (173 vs. 14). Notably, nine chemical classes were exclusively identified by GC x GC, including alkane, alkene, aldehyde, ester, and nitrile BVOCs—each potentially fulfilling undescribed functions in marine organisms. The microalgal species investigated shared a large proportion of BVOCs, and this result was consistent across instruments (97 and 98% shared compounds via GC x GC and GC–MS, respectively), suggesting consistent retrieval of general patterns between instruments.

Over 7500 prawns were tagged across multiple years in three northern NSW spatial management areas, and 786 tagged prawns were recaptured across both jurisdictions. The majority of prawns tended to be recaptured from deeper waters adjacent to, or directly north of, the spatial management areas, but tagging location and release timing influenced recapture patterns. Cohorts tagged early in the growth season showed lower recapture rates, but were larger on average at recapture, and had migrated further. Prawns reached the fishery in the adjacent jurisdiction (Qld) within 54 days-post tagging, but for most cohorts the majority of recaptures were in NSW zones. Overall, there was good connectivity between all spatial management areas and the NSW fishery, and tagged prawns also reached the Qld spawning areas. This represents an optimal scenario for NSW fishers (who forgo capture of prawns within these spatial management areas): the prawns protected in the closure areas primarily contribute to harvest of larger sized prawns within NSW waters; and a portion of the protected prawns survive to reach the southern Queensland spawning grounds, which is the primary source of recruits for northern NSW nurseries. These findings are broadly relevant to defining the role and impact of established and proposed spatial management networks within penaeid fisheries.]]> Mon 14 Nov 2022 15:47:10 AEDT ]]> Organ-specific distribution and size-dependent toxicity of polystyrene nanoplastics in Australian bass (Macquaria novemaculeata) https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:54741 Mon 11 Mar 2024 14:25:54 AEDT ]]> Cyanobacterial blooms in wastewater treatment facilities: significance and emerging monitoring strategies https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:41064 Mon 08 Aug 2022 14:59:49 AEST ]]> Accelerated sea-level rise limits vegetation capacity to sequester soil carbon in coastal wetlands: a study case in southeastern Australia https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:40129 Mon 08 Aug 2022 11:56:57 AEST ]]> Offspring of metal contaminated saltmarsh (Juncus acutus) exhibit tolerance to the essential metal Zn but not the nonessential metal Pb https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:50761 Mon 07 Aug 2023 14:08:10 AEST ]]> The potential of saltmarsh halophytes for phytoremediation of metals and persistent organic pollutants: An Australian perspective https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:53003 Mon 06 Nov 2023 08:45:15 AEDT ]]> Localising terrestrially derived pollution inputs to threatened near-shore coral reefs through stable isotope, water quality and oceanographic analysis https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:51386 Mon 04 Sep 2023 13:11:51 AEST ]]> Global dataset on seagrass meadow structure, biomass and production https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:52694 Fri 20 Oct 2023 16:09:14 AEDT ]]> Legacy metal contamination is reflected in the fish gut microbiome in an urbanised estuary https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:52681 Fri 20 Oct 2023 09:30:49 AEDT ]]> Characteristics of The Bleached Microbiome of The Generalist Coral Pocillopora damicornis from Two Distinct Reef Habitats https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:52655 Fri 20 Oct 2023 08:55:33 AEDT ]]> A review of microplastics aggregation in aquatic environment: influence factors, analytical methods, and environmental implications https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:46355 Fri 18 Nov 2022 10:08:39 AEDT ]]> Non-Lethal Sampling Does Not Misrepresent Trophic Level or Dietary Sources for Sagmariasus Verreauxi (Eastern Rock Lobster) https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:50578 Fri 18 Aug 2023 11:30:25 AEST ]]> Arsenic in the Soil-Plant-Human Continuum in Regions of Asia: Exposure and Risk Assessment https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:54822 Fri 15 Mar 2024 08:36:58 AEDT ]]> Tracking the impacts of nutrient inputs on estuary ecosystem function https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:47369 Fri 13 Jan 2023 15:04:30 AEDT ]]> Altimetry for the future: Building on 25 years of progress https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:49372 Fri 12 May 2023 13:38:02 AEST ]]> Contrasting patterns of population structure in commercially fished sawsharks from southern Australian waters https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:41835 Fri 12 Aug 2022 14:23:17 AEST ]]> An advanced analytical approach to assess the long-term degradation of microplastics in the marine environment https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:53585 Fri 08 Dec 2023 15:46:06 AEDT ]]> Thylakoid fatty acid composition and response to short-term cold and heat stress in high-latitude Symbiodiniaceae https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:52262 Fri 06 Oct 2023 10:25:04 AEDT ]]>
