“…Monitoring valve gape behavior, i.e., the opening and closing of valves, is one way of assessing bivalve responses to environmental conditions. Valve closure has been used as an indicator of adverse conditions such as the presence of contaminants (de Zwart et al 1995;Kádár et al 2001;Soliman et al 2015), toxic algae (Shumway and Cucci 1987;Basti et al 2009;Tran et al 2010), thermal pollution (Shumway and Koehn 1982;Nicastro et al 2012;Dowd and Somero 2013), food quantity (Higgins 1980;Riisgård et al 2006;Robson et al 2010a), feeding regime (Riisgård et al 2006;Robson et al 2010b), emersion (Nicastro et al 2010;Dowd and Somero 2013), photoperiod (Loosanoff and Nomejko 1946;Comeau et al 2012), pH (Pynönnen and Huebner 1995;Jakubowska and Normant-Saremba 2015), and combined pH and dissolved oxygen . A previous study using valve gape responses to DO in oysters, specifically Crassostrea virginica, examined responses only to continuous, rather than cycling, exposures to hypoxia (Lombardi et al 2013).…”

immediately when they encountered severe hypoxia while oysters at mild hypoxia often closed later in the low oxygen phase of the cycles. When normoxia was reintroduced after severe hypoxia, most oysters opened immediately and gaped throughout the period. The results indicate that while 1-yearold oysters responded negatively to diel-cycling low [DO], especially to severe hypoxia, they rapidly opened during the normoxic period that followed, potentially reducing any negative effects of a fluctuating environment.

“…Copper and zinc are micronutrients, necessary for living organisms. However, when they are present at critical levels, these essential elements can result in negative impacts (Soliman et al, 2015). As protection mechanism against excessive exposure, some species present auto detoxification processes, like binding the toxic elements to high affinity sites in inorganic granules, or to various proteins like apoferritin or cysteine‐rich metallothionein (Khati et al, 2012).…”

Contaminant substances consist of chemical elements that present the potential to adversely impact the ecology of the environment, thus representing a threat to local fauna and flora. In this context, heavy metals are critical agents that, depending on the nature and level, are potentially toxic to living organisms. In order to evaluate the bioaccumulation of heavy metals in the Santos estuary and to determine the potential influence of salinity gradient on the heavy metal bioconcentration, the present study measured the concentrations of As, Cd, Pb, Cu, Cr, Fe, Ni, and Zn in two bivalve species (Crassostrea rhizophorae and Perna Perna) sampled at different sites of Santos Bay, in the southeastern region of Brazil. Throughout the study, the “sentinel species” used were effective in bioaccumulating contaminants. In oysters, based on the Brazilian legislation, critical limits were exceeded for As, Zn, Cu, and Cr. In the case of mussels, on the other hand, only for As, Zn, and Cr, the critical limits were overcome. In the present study, obtained data suggested salinity as a determinant parameter in As incorporation processes of bivalve mollusks. Practitioner Points The present study presents important results for the development of environmental management policies in estuarine environments. The present study points out differences between different organisms as biomonitors, providing subsidies for the decision of an effective biomonitoring program. The present study discusses values of contaminants as a danger to public health in Santos Bay, which can be extrapolated to other similar environments around the world.
