“…Accordingly, the BDI values calculated for Brachidontes rodriguezii in winter were the highest in the study period, which suggests a TBT accumulation. Similar behavior had previously been observed in the same sampling sites in 2013 (Quintas et al 2017).…”

“…On the other hand, the lowest values for these coefficients were found in autumn (Table 3). The pumping activity of mussels (Brachidontes rodriguezzi) is clearly reduced at high TBT burdens, which also may lead to a decrease in the TBT uptake efficiency (Choi et al 2009;Quintas et al 2017). In autumn, the levels of TBT in water were found between 168 and 397 ng Sn L -1 , while the presence of TBT could not be detected in the mussel samples.…”

This study evaluates for the first time the distribution and accumulation of butyltin compounds (BTs) in different compartments as seawater, sediments, suspended particulate matter (SPM) and mussels (Brachidontes rodriguezii) in the Bahía Blanca estuary. The samples were collected from six sampling sites with different anthropogenic impact. A better visualization and interpretation of data were achieved using chemometric tools (Tucker4 model), which made it possible to reveal the main relationships between the variables. This analysis showed the presence of BTs in all environmental compartments along the estuary, even in sites with low human intervention. The relationships found between BTs levels, seasons and environmental matrices show the importance of biological processes such as phytoplankton blooms and remobilization of sediments (by tidal dynamics and/or periodic dredging) in the BTs distribution and degradation. In addition, partition coefficients showed that mussels mainly bioaccumulate tributyltin through sediment, water and, to a lesser extent, from SPM.

“…Likewise, it comprises a secondary substratum where the infaunal and epibenthic species may develop assemblages, increasing their structural complexity, diversity, and species richness (Günther 1996). The wide distribution, the condition of the ecosystem engineering (Borthagaray and Carranza 2007), and recent studies considering B. rodriguezii a potential bioindicator of organotin compounds (Quintas et al 2017) grant ecological relevance to this species.…”

The length of aerial exposure (i.e., environmental conditions) of an organism, due to daily tides, induces physiological responses. A mark–recapture field experiment was conducted in two intertidal zones (low tide and high tide) using the stain calcein AM to determine growth, as measured by shell length, of the mussel Brachidontes rodriguezii (d’Orbigny, 1842) along its vertical distribution off the north Argentinean coast. In the high intertidal zone, B. rodriguezii exhibited slower growth in shell length because of the physiological stress resulting from aerial exposure during low tides. In the low intertidal zone and during spring, B. rodriguezii exhibited faster growth in shell length. It is suggested that growth of B. rodriguezii relies on several environmental factors (temperature, photoperiod, and aerial exposure) that fluctuate according to tidal height.

“…Its wide distribution, the condition of ecosystem engineer (Borthagaray and Carranza, 2007) and recent studies considering B. rodriguezii a sentinel species (e.g. Laitano and Fernández-Gimenez, 2016;Oliva et al, 2015Oliva et al, , 2017Quintas et al, 2017;Buzzi and Marcovecchio, 2018;Arrighetti et al, 2019) support the ecological relevance of the species. However, the effect of environmental stress on energy allocation patterns of this species remains unknown.…”
