  • Data for: Life history and physiological responses of native and invasive brine shrimps exposed to Zinc
    Native and invasive artemia were exposed for 21d to 0.2 mg Zn L-1 during which survival and growth rate were measured.On day 21 animals were saved to measure oxidative stress. After 21d organisms were separated and several reproduction parameters were accessed. For more details please check the Material and Methods section of the Manuscript.

  • Data for: Kinetic, physicochemical properties and effects of pesticides and heavy metals on brain acetylcholinesterase of bentonic fish Hoplosternum littorale: Perspectives of application in aquatic biomonitoring
    Highlights 1. Brain ChE from H. littorale was physicochemical and kinetically characterized; 2. Selective inhibitors showed AChE as the main ChE in H. littorale brain; 3. The enzyme was in vitro exposed to eleven pesticides and ten ions; 4. This study presents the first report on the inhibition of cerebral AChE in the Siluriformes group of fish by the pesticides, novaluron and pyriproxyfen; 5. The AChE from H. littorale was highly sensitive to dichlorvos at concentrations (IC20 - IC50) well below the maximum concentrations of this pesticide allowed by the current legislation; 6. Among the ions studied, mercury altered the enzymatic activity most significantly.

  • Seawater carbonate chemistry and polyspermy of a broadcast spawning bivalve
    Ensuring that oocytes are fertilized by a single sperm during broadcast spawning is crucial for the fertilization success of many marine invertebrates. Although the adverse impacts of ocean acidification (OA) on various marine species have been revealed in recent years, its impact on polyspermy and the underlying mechanisms involved remain largely unknown. Therefore, in the present study, the effect of OA on polyspermy risk was assessed in a broadcast spawning bivalve, Tegillarca granosa. In addition, the impacts of OA on the two polyspermy blocking processes, the fast block (membrane depolarization) and the permanent block (cortical reaction), were investigated. The results show that the exposure of oocytes to two future OA scenarios (pH 7.8 and pH 7.4) leads to significant increases in polyspermy risk, about 1.70 and 2.38 times higher than the control, respectively. The maximum change in the membrane potential during oocyte membrane depolarization markedly decreased to 15.79% (pH 7.8) and 34.06% (pH 7.4) of the control value. Moreover, the duration of oocyte membrane depolarization was significantly reduced to approximately 63.38% (pH 7.8) and 21.91% (pH 7.4) of the control. In addition, cortical granule exocytosis, as well as microfilament migration, were significantly arrested by OA treatment. Exposure to future OA scenarios also led to significant reductions in the ATP and Ca2+ content of the oocytes, which may explain the hampered polyspermy blocking. Overall, the present study suggests that OA may significantly increase polyspermy risk in T. granosa by inhibiting membrane depolarization and arresting cortical granule exocytosis.

  • The impact of ocean acidification on the gonads of three key Antarctic benthic macroinvertebrates
    CO2 atmospheric pressure is increasing since industrial revolution, leading to a lowering of the ocean surface water pH, a phenomenon known as ocean acidification, with several reported effects on individual species and cascading effects on marine ecosystems. Despite the great amount of literature on ocean acidification effects on calcifying organisms, the response of their reproductive system still remains poorly known. In the present study, we investigated the histopathological effects of low pH on the gonads of three key macroinvertebrates of the Terra Nova Bay (Ross Sea) littoral area: the sea urchin Sterechinus neumayeri, the sea star Odontaster validus and the scallop Adamussium colbecki. After 1 month of exposure at control (8.12) and reduced (7.8 and 7.6) pH levels, we dissected the gonads and performed histological analyses to detect potential differences among treatments. Results showed significant effects on reproductive conditions of A. colbecki and S. neumayeri, while O. validus did not show any kind of alteration. Present results reinforce the need to focus on ocean acidification effects on soft tissues, particularly the gonads, whose damage may exert large effects on the individual fitness, with cascading effects on the population dynamic of the species.

  • The relative importance of waterborne and dietborne As exposure on survival and growth of juvenile fathead minnows.
    This dataset provides exposure and effects data for two experiments regarding the dietborne toxicity of inorganic arsenic on fathead minnows survival and growth. There are separate spreadsheets for the two experiments, at the replicate exposure chamber level, of fish exposure, survival, and weights and calculated growth metrics. Each spreadsheet provides footnote descriptions of the data and calculations provided. Descriptions of experimental protocols are also provided as supporting documents.
