“…This species accounts for the world's second largest tuna fishery with annual landings in excess of 1.25 million pounds (Pecoraro et al, 2018(Pecoraro et al, , 2017. As apex predators they can accumulate high levels of marine pollutants, with the primary concern about these pollutants on their potential transfer to humans who eat the tuna (Choy et al, 2009;Nicklisch et al, 2017aNicklisch et al, , 2017bPulster et al, 2020;Xie et al, 2020). Less understood are the potential impacts of these bioaccumulative pollutants on the tuna themselves.…”

Marine pollutants bioaccumulate at high trophic levels of marine food webs and are transferred to humans through consumption of apex species. Yellowfin tuna (Thunnus albacares) are marine predators, and one of largest commercial fisheries in the world. Previous studies have shown that yellowfin tuna can accumulate high levels of persistent organic pollutants, including Transporter Interfering Chemicals (TICs), which are chemicals shown to bind to mammalian xenobiotic transporters and interfere with their function. Here, we examined the extent to which these same compounds might interfere with the activity of the yellowfin tuna (Thunnus albacares) ortholog of this transporter. To accomplish this goal we identified, expressed, and functionally assayed tuna ABCB1. The results demonstrated a common mode of vertebrate ABCB1 interaction with TICs that predicts effects across these species, based on high conservation of specific interacting residues. Importantly several TICs showed potent inhibition of Ta-ABCB1, such as the organochlorine pesticides Endrin (EC 50 = 1.2 ± 0.2 μM) and Mirex (EC 50 = 2.3 ± 0.9 μM). However, unlike the effects observed on mouse ABCB1, low concentrations of the organochlorine pesticide TICs p,p'-DDT and its metabolite p,p'-DDD co-stimulated verapamil-induced Ta-ABCB1 ATPase activity possibly suggesting a low transport activity for these ligands in tuna. These results provide a mechanistic basis for understanding the potential vulnerability of tuna to these ubquitous pollutants.

“…Because of the estuarine dependence of juveniles and adults of both species, they were subject to exposure in marsh areas contaminated with oil. Pulster et al (2020) documented high concentrations of PAH metabolites in bile (indicative of recent exposure) of large juvenile and adult Red Drum sampled in Barataria and Terrebonne Bays in summer 2011. Likewise, Powers and Scyphers (2016) documented significantly depressed juvenile Red Drum growth in mesocosms deployed adjacent to oiled marsh edges, as compared to control sites.…”

A Synthesis of Deepwater Horizon Impacts on Coastal and Nearshore Living Marine Resources

The 2010 Deepwater Horizon (DWH) oil blowout in the Gulf of Mexico began on April 20, originating in the deep sea 66 km off the Louisiana coast. By early June, DWH oil had spread to coastal Louisiana, Mississippi, Alabama and western Florida. An estimated 2,113 km of shoreline were oiled, making DWH the largest marine oil spill in global history by length of affected shoreline. Additionally, a series of oil spill response measures were deployed, including diversions of Mississippi River discharge to forestall oil coming ashore, and the establishment of large-scale fishery closures, with both affecting coastal resources to varying degrees. Here, we review published studies and describe additional analyses evaluating long-term impacts of DWH on coastal/nearshore biological resources. We assembled time-series data collected by state, federal and academic partners on population abundance and environmental conditions to evaluate species and community change. Our study focused on plankton, invertebrates, fishes and dolphins, and 13 “key species” were selected to conduct semi-quantitative vulnerability-resilience (V-R) analyses. At one extreme, early life stages of Gulf Menhaden (Brevoortia patronus) were not affected due to seasonal spawning and larval development preceding the spill. In contrast, demographically independent populations of the common Bottlenose Dolphin, (Tursiops truncatus) suffered a variety of severe and ongoing health effects owing to oil exposure. Virtually all of the heavily oiled salt marsh habitat was in Louisiana, with the majority occurring in Barataria Bay. Multispecies trawl survey abundances declined post-DWH throughout eastern coastal Louisiana but remained stable elsewhere. A regime shift in composition of Barataria Bay trawl survey catches occurred during and following the spill, the persistence of which was associated with long-term reductions in average salinity and increases in water clarity. In some cases, fishery closures were associated with measurable but ephemeral increases in abundance of some targeted and bycatch species. Freshwater flooding of marshes was ineffective in preventing coastal oiling and severely affected benthic euryhaline resources including Eastern Oyster (Crassostrea virginica) and Marsh Periwinkle (Littoraria irrorata). The flooding response measure experiment also indicates the directionality of impacts that further planned water diversions may have on ecological communities of lower Mississippi River basins.

“…The persistence of oil and its effects in these ecosystems is poorly understood. A recent landmark survey, published in the journal Nature, found that astonishing amounts of hydrocarbons were still present in over ninety species of fish a decade after the explosion; in other words, across the entire trophic chain of the region (Pulster et al, 2020). 11.…”

The Anthropocene Review

View full text Add to dashboard Cite

As the physical impacts of the Anthropocene begin to make themselves felt around the globe, maintaining current levels of economic prosperity, in many communities, will consume an increasing portion of public finances. This is because existing investments in property and capital will require new forms of protection if they are to continue generating stable streams of public revenue. Since Anthropocene impacts are unevenly distributed, some territories will be under more pressure than others to shift limited public spending to cope with growing levels of exposure. The sinking of Louisiana’s coastal wetlands provides a clear example of this trend of accelerating local vulnerability due to human-induced environmental change. With the bulk of state revenue tied to activities concentrated along Louisiana’s coasts, the state’s Coastal Protection and Restoration Authority has launched an ambitious plan of government-backed expenditures that seek to defend the economic viability of these zones. Yet, many actions aimed at preventing immediate loss also work to secure incumbent extractive industries, such as offshore oil and gas drilling, which themselves contribute to the very vulnerabilities requiring state intervention in the first place. This paper, borrowing from the environmental sociology of Allan Schnaiberg, considers the social consequences of this dynamic, dubbed the “treadmill of protection.”
