Abstract:
Abstract. Marine nitrogen fixation is co-limited by the supply of iron (Fe) and phosphorus in large regions of the global ocean. The deposition of soluble aerosol Fe can initiate nitrogen fixation and trigger toxic algal blooms in nitrate-poor tropical waters. We present dry season soluble Fe data from the Savannah Fires in the Early Dry Season (SAFIRED) campaign in northern Australia that reflects coincident dust and biomass burning sources of soluble aerosol Fe. The mean soluble and total aerosol Fe concentrations were 40 and 500 ng m−3 respectively. Our results show that while biomass burning species may not be a direct source of soluble Fe, biomass burning may substantially enhance the solubility of mineral dust. We observed fractional Fe solubility up to 12 % in mixed aerosols. Thus, Fe in dust may be more soluble in the tropics compared to higher latitudes due to higher concentrations of biomass-burning-derived reactive organic species in the atmosphere. In addition, biomass-burning-derived particles can act as a surface for aerosol Fe to bind during atmospheric transport and subsequently be released to the ocean upon deposition. As the aerosol loading is dominated by biomass burning emissions over the tropical waters in the dry season, additions of biomass-burning-derived soluble Fe could have harmful consequences for initiating nitrogen-fixing toxic algal blooms. Future research is required to quantify biomass-burning-derived particle sources of soluble Fe over tropical waters.

Abstract:
Quantifying health in wild marine turtles is challenging because reptiles have characteristically wide-ranging normal reference values for many indicators of health and because of the shortage of population-specific baseline data for wild animals. We measured blood biochemistry profiles (calcium, magnesium, sodium, lactate dehydrogenase (LDH), urea, cholesterol, triglycerides, and glucose) of green turtles (Chelonia mydas) in Moreton and Shoalwater Bays, Australia, and compared them in relation to capture site, age, sex and exposure to harmful algal blooms of the toxic cyanobacteria Lyngbya majuscula. Turtles were considered to be clinically healthy when no external injuries or lesions were observed and there was no evidence of disease or emaciation. Differences in blood profiles were detected between sites, but not between age groups or sexes. Turtles that were exposed to L. majuscula generally had lower plasma glucose concentrations and decreased LDH activity, which may represent a metabolic downregulation resulting from food limitation. This study provides the first blood biochemistry reference values for green turtles in Queensland, Australia, that can be used in future assessments of green turtles in these foraging habitats.

Abstract:
Highlight Research Brown seaweed heavy metals content varies between species Risk assessment showed low health risk for heavy metal from intake of the three brown seaweed The three types of brown seaweed did not show carcinogenic properties to metal Arsenic (As) Abstract Marine brown seaweed are known as one of the potential biological agents to be developed as functional food and medicinal sectors. This study aims to examine the concentration of heavy metals (Pb, Cd, Hg, and As) in brown algae (Sargassum aquifolium, Padina australis, and Turbinaria ornata.) and the possible exposure to health risks caused by consumption. Heavy metal concentrations were determined using Atomic Absorption Spectroscopy (AAS) on brown seaweed samples obtained from three different sites. The average concentration of heavy metals in the dry weight of brown seaweed remains within the guidelines established by The Food and Drug Supervisory Agency (BPOM) Number 32 of 2019 concerning the Safety and Quality of Traditional Medicines, which is then used to calculate the estimated daily intake (EDI), target hazard quotient (THQ and TTHQ), and target cancer risk (TCR) for arsenic associated with food exposure to potentially toxic metallic elements. Each species of brown seaweed has a THQ and TTHQ level of <1, indicating that one or more toxic metal elements in the same meal provide no significant non-carcinogenic risk. The TCR for arsenic in these seaweeds are all less than 1 x 10-4, indicating no cancer risk. There are no chronic health hazards related with the ingestion of brown seaweed harvested from the coast of Sanur Beach at Denpasar, Bali.

Abstract:
Micropollution is a serious environmental problem caused by continuous entry of trace quantities of toxic chemical substances into the aquatic environment. In the present study, three trophic levels of the aquatic ecosystems were used to evaluate the acute toxicities of environmentally important micropollutants including heavy metals, pesticides and drugs. There is a scarcity of information on toxicity of the studied substances on marine water algae. Among studied micropollutants, the most toxic chemical to Daphnia magna and Danio rerio was found to be 1-Chloro-2,4 dinitrobenzene with EC50 of 0.002 and 4.2 mg/L, respectively. Although this compound was also toxic to marine algae, Phaeodactylum tricornutum, arsenic showed the highest toxicity to the algae with EC50 of 2.4 mg/L. As compared to other organisms, D. magna was found to have higher sensitivity to all of the tested micropollutants.

Full text
Abstract:
Detached macrophytes (sea grass and macroalgae) are transported from more offshore areas and accumulate in large volumes in surf zones, where they are commonly called wrack. In coastal regions in other parts of the world, wrack transported from one habitat to a second habitat can be considered as a "spatial subsidy" for the recipient habitat with significant consequences for community dynamics and food webs. The primary aim of this study was to determine the significance of the different components of wrack (i.e. sea grass and brown, red and green algae) as a direct and indirect food source and habitat for invertebrates and fish in surf zones of south-western Australia. The importance of different volumes of surf zone wrack to determining fish abundance and composition was also investigated. These aims were achieved by examining the food and habitat preference of invertebrates and the habitat preference of fish through laboratory trials and field experiments. Gut content analysis was used to examine the importance of wrack-associated invertebrates as a food source for fish, while stable isotope analysis (carbon, nitrogen and sulfur) and lipid analysis (lipid class and fatty acid composition) were conducted on macrophytes, amphipods and fish to determine the source of nutrients and energy. The composition of surf zone wrack in the region comprises large quantities of seagrass, then brown and red algae, with negligible quantities of green algae. Allorchestes compressa, the dominant macroinvertebrate in surf zone wrack, showed a preference for consuming brown algae over other macrophyte types. Similarly, stable isotope analysis from some locations and fatty acid analyses indicated that A. compressa assimilates nutrients predominantly from brown algae. The influence of brown algae on secondary production extends to second-order consumers. Allorchestes compressa was the major prey of juveniles of the cobbler Cnidoglanis macrocephalus and the sea trumpeter Pelsartia humeralis, the main fish species in surf zone wrack accumulations in the region. Detached brown algae therefore contributes most to the detached macrophyte - amphipod - fish trophic pathway in the surf zones, and thus drives secondary production in these regions and provides a crucial link between coastal ecosystems. Detached macrophytes also provide an important, but transient, habitat for invertebrates and fish in south-western Australia. Under laboratory conditions, Allorchestes compressa showed a strong preference for inhabiting seagrasses over macroalgae, iii however in situ caging experiments showed that A. compressa has a strong preference for brown algae, red algae or a mixture of macrophytes, but tended to avoid seagrass. Therefore, A. compressa showed a clear preference for different types of detached macrophytes as a habitat, with seagrass ranking below other types of macrophyte under field conditions. In contrast, neither Cnidoglanis macrocephalus or Pelsartia humeralis showed a preference for inhabiting different types of detached macrophytes as a habitat, but showed a strong positive influence by increasing volumes of wrack The species composition, densities and biomass of fish, which were dominated by juveniles, were strongly influenced by increasing volume of wrack in surf zones of south-western Australia. This study has shown that both the type and volume of detached macrophytes transported from more offshore regions subsidizes consumers and plays a crucial role in supporting secondary production in less productive surf-zone habitats of south-western Australia. The removal of large amounts of wrack from nearshore areas could have a detrimental impact on the biodiversity or abundance of macroinvertebrate and fish populations, which rely on wrack for food and shelter.

Abstract:
The marine diatom genus Pseudo-nitzschia includes species that produce domoic acid, a neurotoxin responsible for illness and mortality in both humans and marine wildlife. Because of the expertise and time required for the microscopic discrimination of species, molecular methods that monitor environmental concentrations of Pseudo-nitzschia provide a rapid alternative for the early detection of blooms and prediction of toxin accumulation. We have developed a nucleic acid sequence-based amplification with internal control RNA (IC-NASBA) assay and a quantitative reverse transcription PCR (qRT-PCR) assay for the detection of the toxic species P. multiseries targeting the ribulose- 1,5-biphosphate carboxylase/oxygenase small subunit (rbcS) gene. Both methods use RNA amplification and fluorescence-based real-time detection. Due to a limited rbcS sequence database, primers were designed and used to sequence this gene from 14 strains of Pseudo-nitzschia (including four P. multiseries) and 19 other marine diatoms. The IC-NASBA and qRT-PCR assays had a limit of detection of one cultured cell of P. multiseries and were linear over four and five orders of magnitude, respectively (r2 ! 0.98). Neither of the assays detected closely related organisms outside the Pseudo-nitzschia genus, and the qRT-PCR assay was specific to P. multiseries. While cross-reactivity of primers with unknown species prevented reliable detection of P. multiseries in spiked environmental samples using IC-NASBA, the qRT-PCR assay had positive detection from 107 cells/L to 103 cells/L. Nearly a 1:1 relationship was observed between predicted and calculated cell concentrations using qRT-PCR. Based on a diel expression study, the rbcS transcript copy number per cell ranged from 2.16 x 104 to 5.35 x 104, with the highest expression during early to mid photoperiod. The rbcS qRT-PCR assay is useful for the detection and enumeration of low concentrations of P. multiseries in the environment.

Abstract:
Algae are distributed worldwide in the sea, in freshwater and in wet situations on land. Most are microscopic algae, but some of them are so large, also some marine seaweeds that can exceed 50 m in length. The algae have chlorophyll and can make their own food through the steps of photosynthesis. Recently they are classified in the kingdom of protested, which include a variety of unicellular and some basic multinuclear and multicellular eukaryotic organisms that have cells. Algal poisoning is an intense, often lethal condition caused by high concentrations of toxic blue-green algae (more commonly known as cyanobacteria—literally blue-green bacteria) in drinking water as well as in water used for recreation, agriculture and aquaculture. The study cur in the productive dangerous from the algae toxin that productive from cyanobacteria in aquatic environment. The important contamination for water source identification and non-identification and identify on algae that responsible on productive of toxin in water that represented by Cylindrospermum, Aphanizomenon Anabaena, Microcystis, Lyngbya, Oscillatoria, phormidium, and suitable environment for algae to productive toxin.

Abstract:
Climate change is one of the major global concerns jeopardizing human health and wildlife. This event is considered a threat to the marine ecosystem as well. Marine algae are the leading producer in the benthic food chain. Therefore, any change in marine algal communities will disrupt the whole ecosystem. Currently, algal species face significant changes in their abundance and distribution worldwide. Toxic species are frequently invading and causing a phenomenon called the harmful algal bloom, which threatens the seafood industry and public health. This chapter will focus on the significant distribution of algal communities worldwide and the impact of climate change on these marine algal species. Besides, this chapter will shed some light on how these changes affect the marine food chain and ultimately affect human health.
