Biomonitoring Climate Change and Pollution in Marine Ecosystems: A Review on Aulacomya ater
(Hindawi Publishing Corporation, 2016-08)
The sedentarism and wide global distribution of the blue mussel Mytilus edulis have made it a useful bioindicator to assess changes in the health status of the marine ecosystem in response to pollution and other environmental ...
Fishers' ecological knowledge about marine pollution: What can fek contribute to ecological and conservation studies of a southwestern atlantic estuary?
(Herpetologists League, 2019-12-20)
The growth of human populations and industrial activities in the last decades have been the major cause of ecosystem decline, especially due to the inputs of several pollutants in the environment. Estuaries are one of the ...
Fishing plastics: A high occurrence of marine litter in surf-zone trammel nets of Southern Brazil
(Pergamon-Elsevier Science Ltd, 2021-12)
Plastic is one of the most commonly found residues in the marine environment, which can cause several impacts. This study evaluated the interaction of marine litter with surf-zone trammel nets in Southern Brazil. Fifty ...
Ulva lactuca: A bioindicator for anthropogenic contamination and its environmental remediation capacity
(Elsevier, 2021-08)
Coastal regions are subjected to degradation due to anthropogenic pollution. Effluentsloaded with variable concentrations of heavy metal, persistent organic pollutant, as wellas nutrients are discharged in coastal areas ...
Synthetic microfibers in marine sediments and surface seawater from the Argentinean continental shelf and a Marine Protected Area
(Pergamon-Elsevier Science Ltd, 2019-12)
In this work, samples were collected from the Argentinean continental shelf –including a Marine Protected Area (MPA) - to assess the occurrence and distribution of synthetic microfibers (MFs), a widespread type of microplastic. ...
Assessing urban microplastic pollution in a benthic habitat of Patagonia Argentina
(Elsevier Science, 2020-10)
Plastic pollution in the oceans has become a global problem, but its documentation is disparate around the world. We assess the abundance and type of microplastics in three benthic matrices: mussels, small fishes, and ...
Marine debris in beaches of the Southwestern Atlantic: An assessment of their abundance and mass at different spatial scales in northern coastal Argentina
(Pergamon-Elsevier Science Ltd, 2017-06)
Argentina is currently undergoing an intensive development of coastal-oriented tourism due to the temperate climate and coastal sceneries of the Southwestern Atlantic and particularly its wide ocean-open sandy beaches, ...
Aromatic hydrocarbon degradation genes from chronically polluted Subantarctic marine sediments
(Wiley Blackwell Publishing, Inc, 2009-11)
Aim: The goal of this study was to identify functional targets to detect polycyclic aromatic hydrocarbon (PAH)-degrading bacterial populations in cold marine ecosystems. Methods and Results: We designed a degenerate primer ...
Trace elements in trophic webs from South Atlantic: The use of cetaceans as sentinels
(Pergamon-Elsevier Science Ltd, 2020-01)
The odontocetes are at the top of the trophic chains, and because they accumulate numerous compounds throughout life, they are considered as bioindicators of ecosystem contamination. This study aimed to analyze the ...
Marine debris ingestion by the South American Fur Seal from the Southwest Atlantic Ocean
(Pergamon-Elsevier Science Ltd, 2017-07-08)
In this paper, we examined the ingestion of marine debris (MD) in South American fur seals (SAFS), Arctocephalus australis, found dead in coastal beaches of northern Argentina and southern Brazil. Seven percent of 133 SAFS ...
