“…The immune functions of coelomocytes are thought to include antibacterial activity, clotting, oxygen transport, chemotaxis and phagocytosis [19]. Red amoebocyte levels are suggested to be a bioindicator of abiotic stress such as from increased temperature or pollution [22,23].…”

Sea urchins in a high-CO ₂ world: the influence of acclimation on the immune response to ocean warming and acidification

Climate-induced ocean warming and acidification may render marine organisms more vulnerable to infectious diseases. We investigated the effects of warming and acidification on the immune response of the sea urchin Heliocidaris erythrogramma Sea urchins were gradually introduced to four combinations of temperature and pHNIST (17°C/pH 8.15, 17°C/pH 7.6, 23°C/pH 8.15 and 23°C/pH 7.6) and then held in temperature-pH treatments for 1, 15 or 30 days to determine if the immune response would adjust to stressors over time. Coelomocyte concentration and type, phagocytic capacity and bactericidal activity were measured on day 1, 15 and 30 with different sea urchins used each time. At each time point, the coelomic fluid of individuals exposed to increased temperature and acidification had the lowest coelomocyte concentrations, exhibited lower phagocytic capacities and was least effective at inhibiting bacterial growth of the pathogen Vibrio anguillarum Over time, increased temperature alleviated the negative effects of acidification on phagocytic activity. Our results demonstrate the importance of incorporating acclimation time to multiple stressors when assessing potential responses to future ocean conditions and indicate that the immune response of H. erythrogramma may be compromised under near-future ocean warming and acidification.

“…For example, genes encoding the cold shock proteins have been reported to activate and participate after injury in the regenerative processes in planaria [50]. Moreover, numerous data show that pigmentation in sea urchins may occur in response to different stresses [5,13,14,32,37,53]. We suppose that an expression analysis of genes involved in pigment differentiation in sea urchins [4,9,15] may help to identify changes in pigment differentiation that occur in sea urchin cells after freezing-thawing.…”

“…The potential effects of global warming on the immune system of the Antarctic sea urchin (Sterechinus neumayeri) were examined by Branco et al (2012). One day of exposure to a 2˚C increase in temperature caused an increase in the percentage of red sphere cells, phagocytic capacity, and percentage of iron crystalloid, but the effect was not seen at 4˚C, or in longer exposure durations at (2-14 days).…”

This review covers selected 2012 articles on the biological effects of pollutants and human physical disturbances on marine and estuarine plants, animals, ecosystems and habitats. The review, based largely on journal articles, covers field and laboratory measurement activities (bioaccumulation of contaminants, field assessment surveys, toxicity testing and biomarkers) as well as pollution issues of current interest including endocrine disrupters, emerging contaminants, wastewater discharges, dredging and disposal, etc. Special emphasis is placed on effects of oil spills and marine debris due in part to the 2010 Deepwater Horizon oil blowout in the Gulf of Mexico and the 2011 Japanese tsunami. Several topical areas reviewed in the past (ballast water and ocean acidification) were dropped this year. The focus of this review is on effects, not pollutant fate and transport. There is considerable overlap across subject areas (e.g. some bioaccumulation papers may be cited in other topical categories). Please use keyword searching of the text to locate related but distributed papers. Use this review only as a guide and please consult the original papers before citing them.
