Beddoe J, Shimeta J, Klaassen M, Robb K. Population distribution and drivers of habitat use for the Burrunan dolphins, Port Phillip Bay, Australia. Ecol Evol 2024; 14:e11221. [PMID: 38584772 PMCID: PMC10994984 DOI: 10.1002/ece3.11221] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2023] [Revised: 03/08/2024] [Accepted: 03/20/2024] [Indexed: 04/09/2024] Open
Abstract
Bottlenose dolphin (Tursiops) populations, also described as the Burrunan dolphins, consist of a resident population of approximately 150 individuals in Port Phillip Bay (PPB), Victoria. Previous reports indicate distribution across a small southern region of PPB; however, little is known about their full distribution patterns across the entire PPB region. Here, we investigate the spatiotemporal distribution of the Burrunan dolphins across four zones representative of PPB benthic habitats and bathymetry to gain a better understanding of the potential drivers of the population's habitat use. Port Phillip Bay, Victoria, Australia. One hundred and twenty-nine boat-based surveys were undertaken between March 2015 and August 2021, encompassing 181 sightings. Generalised linear models (GLMs) were used to investigate annual, seasonal and zonal variation. We found no variation in sighting frequencies between years. Austral summer and winter had a significantly higher sighting frequency than autumn. We found that Burrunan dolphins utilise the entire bay, further extending the species range, and show a significantly higher number of sightings in the southern zone than in any other zones. Overlaying dolphin sightings with known oceanographic characteristics within PPB, we found bathymetry and benthic habitats were potential drivers for the Burrunan dolphins distribution and habitat use within the bay, with the dolphins significantly favouring the 5-10 and 10-15 m contour depths. These results show a more widespread distribution across the bay than previously documented. We recommend expansion of the current marine protected areas in the north and south of the bay. This study has increased our understanding of the vital habitat for the Burrunan dolphin populations. By providing evidence-based conservation recommendations, we hope to improve and contribute to future research, conservation management plans and effective marine protected areas across PPB for the resident Burrunan dolphin population.

ENVIRONMENTAL POLLUTION (BARKING, ESSEX : 1987) 2023; 335:122245. [PMID: 37487873 DOI: 10.1016/j.envpol.2023.122245] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/26/2023] [Revised: 07/02/2023] [Accepted: 07/20/2023] [Indexed: 07/26/2023]
Abstract
Mussels were collected from four coastal sites around Port Phillip Bay, Australia in Mar and Apr 2021). Body burdens of Polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), and organochlorine pesticides (OCPs) were measured and the possible sources of toxicants discussed. In addition, a gas chromatography-mass spectrometry (GC-MS) based untargeted metabolomics analysis was performed using the mantle tissues of mussels. Correlations between the results of contaminant body burdens and metabolic variations were investigated. The results demonstrated that high accumulations of low-molecular-weight PAHs were found in mussels. High body burdens of PCBs and OCPs were only found at mussels from the site close to the river mouth. Some of the metabolic pathways were correlated with the accumulation of PAHs. No correlations were found between PCB and OCP accumulations and metabolic abundances. According to the food and environmental standards of the European Union (EU), the PAH, PCB, and OCP accumulation in mussels in this study are a serious food safety concern.

Abstract
Cadmium (Cd) is a toxic environmental contaminant, which bio-accumulate in animals through the food chain. Cerebellum is one of the primary target organs for Cd exposure. In this study, we established a chronic Cd exposure model; 60 chickens were treated with Cd (0 mg/kg, 35 mg/kg, 70 mg/kg) for 90 days. Clinical manifestations indicated that the chicken was depressed and has unstable gait under Cd exposure. Histopathological results indicated that Cd induced neuronal shrunken and indistinct nucleoli, and the number of Purkinje cells decreased significantly. Cerebellar metal contents were analyzed by ICP-MS. We found that Cd caused Cd and Cu accumulation and decreased the content of Se, Fe, and Zn, suggesting that Cd disturbed metal homeostasis. Besides, Cd treatment group also showed high levels of malondialdehyde (MDA) and hydrogen peroxide (H2O2) content and inhibited selenoprotein transcriptome, suggesting that Cd exposure resulted in oxidative stress. Notably, low-dose Cd exposure activated MTF1 mRNA and protein expression and its target metal-responsive genes, including MT1, MT2, DMT1, ZIP8, ZIP10, TF, and ATP7B which indicate cellular adaptive response against Cd-induced damage. On the other hand, 70 mg/kg Cd downregulated MTF1-mediated metal response, which was involved in Cd-induced cerebellar injury in chicken. In conclusion, our data demonstrated that molecular mechanisms are associated with Cd-induced cerebellar injury due to disturbing MTF1-mediated metal response.

Differential gene expression and chemical patterns of an intertidal crab inhabiting a polluted port and an adjacent marine protected area. THE SCIENCE OF THE TOTAL ENVIRONMENT 2022; 822:153463.

Abstract
The acquisition of data to safeguard marine protected areas located close to ports is important in order to develop plans that allow effective protection from pollution as well as sustainable development of the port. The area Secche della Meloria is a Marine Protected Area (MPA-MEL) three miles from Livorno Harbour (LH), which is characterized by a long history of pollution. Here we studied the bioaccumulation and transcriptomic patterns of the marbled crab, Pachygrapsus marmoratus (Fabricius, 1787) (Crustacea; Brachyura, Grapsidae), inhabiting the two selected sites. Results showed that the two crab populations are significantly different in their chemical composition of trace elements and Polyciclic Aromatic Hydrocarbons (PAHs), and gene expression patterns (1280 DEGs). Enrichment analysis indicated that crabs at LH had the highest stress response genes, and they were associated with higher levels of bioaccumulation detected in body tissues. We are confident that the significant differential gene expression profiles observed between crabs, characterized by significant chemical differences, is associated with responses to contaminant exposure.

Abstract
Wild Mediterranean mussels (Mytilus galloprovincialis) were collected from 10 coastal sites of Port Phillip Bay, Australia, and 16 types of Polycyclic aromatic hydrocarbons (PAHs) in their bodies were measured. Also, mussels from 4 of the 10 sites were sampled and the activities of Metallothioneins (MTs), superoxide dismutase (SOD), glutathione S-transferase (GST), and Ethoxyresorufin -o- deethylase (EROD) in the gills were tested. The results demonstrated spatial variation of different PAHs in mussels, which differed from trace metal accumulations to mussels reported in previous studies. Besides, the results of SOD, GST, and EROD showed highly similar features among mussels from all the sites while the results of MTs appeared to be different. The estimation of possible excessive cancer risks caused by wild mussel consumption using the results in this study demonstrated that the PAHs in wild mussels in Port Phillip Bay is a moderate concern for consumers.

Abstract
The Pacific Island Countries and Territories (PICTs) are heavily dependent on the marine resources for food security, employment, government revenue and economic development, hence the concern about the potential exposure of these resources to pollutants. The main goal of this review was to identify ecotoxicology studies published that were done in PICTs. Four major gaps were identified: i) a quantitative gap, with low number of studies published on the PICTs; ii) a geographic gap, where ecotoxicology studies have unevenly covered the different PICTs; iii) a temporal gap, as no biological effect monitoring study has so far been published for the PICTs; and, iv) a pollutants gap, as all of the PICTs studies focused mainly on environmental monitoring studying on average two types of pollutants (heavy metals and pesticides) per PICT only. We suggest, therefore, the potential risk to the marine environment to be estimated by assessing the fate of pollutants via chemical and biological effect monitoring.

Abstract
This exploratory study aims to investigate the health of sand flathead (Platycephalus bassensis) sampled from five sites in Port Phillip Bay, Australia using gas chromatography-mass spectrometry (GC-MS) metabolomics approaches. Three of the sites were the recipients of industrial, agricultural, and urban run-off and were considered urban sites, while the remaining two sites were remote from contaminant inputs, and hence classed as rural sites. Morphological parameters as well as polar and free fatty acid metabolites were used to investigate inter-site differences in fish health. Significant differences in liver somatic index (LSI) and metabolite abundance were observed between the urban and rural sites. Differences included higher LSI, an increased abundance of amino acids and energy metabolites, and reduced abundance of free fatty acids at the urban sites compared to the rural sites. These differences might be related to the additional energy requirements needed to cope with low-level contaminant exposure through energy demanding processes such as detoxification and antioxidant responses as well as differences in diet between the sites. In this study, we demonstrate that metabolomics approaches can offer a greater level of sensitivity compared to traditional parameters such as physiological parameters or biochemical markers of fish health, most of which showed no or little inter-site differences in the present study. Moreover, the metabolite responses are more informative than traditional biomarkers in terms of biological significance as disturbances in specific metabolic pathways can be identified.

Abstract
The aim of this study was to evaluate the environmental quality of a port in Brazil using the renal alterations in Sciades herzbergii as biomarkers of aquatic contamination. Samples of S. herzbergii were collected in two areas in São Marcos Bay, Brazil: (A1) Itaqui Port (potentially impacted area); and (A2) Puca Creek (control area). At the same time, the abiotic data was obtained, in addition to the sampling of water for metals analysis. The fish kidney of each specimen was submitted to the usual histological technique. It was possible to identify alterations such as melanomacrotic centers, dilation of the glomeruli, capillary endothelium gap, occlusion of the tubular lumen, immature nephron and dilated vessels. Samples of S. herzbergii collected in the port region showed a higher frequency of renal alterations, indicating that the organisms present in that region are probably suffering due to the impacts caused by the port activities.

Abstract
In recent years, the unique properties of nanoparticles have fostered novel applications in various fields such as biology, pharmaceuticals, agriculture, and others. Unfortunately, their rapid integration into daily life has also led to environmental concerns due to uncontrolled release of nanoparticles into the aquatic environment. Despite increasing awareness of nanoparticle bioaccumulation in the aquatic environment, much remains to be learned about their impact on aquatic organisms and how to best monitor these effects. Herein, we provide the first review of innate immunity as an emerging tool to assess the health of fish following nanoparticle exposure. Fish are widely used as sentinels for aquatic ecosystem pollution and innate immune parameters offer sensitive and reliable tools that can be harnessed for evaluation of contamination events. The most frequent biomarkers highlighted in literature to date include, but are not limited to, parameters associated with leukocyte dynamics, oxidative stress, and cytokine production. Taken together, innate immunity offers finite and sensitive biomarkers for assessment of the impact of nanoparticles on fish health.

Abstract
Pollutants have been proposed as one factor in the worldwide declines of amphibian species and populations. Applying gene expression analysis of liver RNA in tadpoles would be a possible approach for biomarker measurements to increase knowledge of ecological health in amphibian populations. The major aim of this study was to explore the relevance of applying gene expression analyses of cytochrome p450 (cyp1a), metallothionein (mt), and vitellogenin (vtg) in Rana temporaria tadpoles. Therefore, tadpoles were exposed for 1 week to β-naphthoflavone (BNF), cadmium chloride (CdCl2), and ethinylestradiol (EE2). Primers were developed for RT-qPCR to analyze gene expression in livers. The result showed that the methods for gene expression analyses of cyp1a, mt, and vtg as well as the reference gene β-actin (bact) were successful not only in R. temporaria but also in another amphibian, Rana arvalis. The gene expression of cyp1a was induced by BNF and the gene expression of mt was induced by CdCl2 but no significant induction was recorded in vtg expression after exposure to EE2. Gene expressions varied throughout the tadpole metamorphosis development, in particular for vtg. Overall, the use of gene expression of cyp1a and mt as biomarkers in wild tadpoles seems promising while the use of vtg seems less relevant due to high natural variation and low background expression. The study shows that variations in gene expressions between tadpoles of different genetic origin are important to consider when evaluating the data. The present study has thus increased the background knowledge about gene expression applicability as biomarker for tadpoles.

Abstract
Hepatic gene expression and gill histology were measured in sand flathead (Platycephalus bassensis) from a metal polluted estuary. The gene expression analyses were conducted on fish from two most polluted sites and a reference site. The metal-related genes were metal-regulatory transcription factor 1 (MTF1), transferrin (TF), ferriportin1 (FPN1), ferritin and metallothionein. The transcripts of MTF1, TF, and FPN1 were significantly higher in the liver of fish caught at polluted sites, suggesting these genes are potential biomarkers for environmental exposure to metal. Strong correlations were found between the transcripts of these three genes. Four types of gill lesions such as hyperplasia and lamellar fusion, epitheliocystis, telangiectasis, and deformed filament were observed in sampled fish. There was significant difference in the prevalence of epitheliocystis and telangiectasis between the fish from the polluted areas and reference area. Gill parasites were less prevalent in the flathead from polluted sites. The gill histopathological results indicated both pollutants and infections could contribute to gill lesions.
