Potentially toxic elements and biochemical components in surface sediments of NW Mexico: An assessment of contamination and trophic status
(Pergamon-Elsevier Science Ltd, 2019-12)
Concentrations of Potentially Toxic Elements (PTEs) were determined in sediments from Santa María La Reforma (SAMARE) coastal lagoon and Mocorito River, Mexico. Furthermore, biochemical composition of organic matter in ...
Historical shell form variation in Lottia subrugosa from southeast Brazilian coast: Possible responses to anthropogenic pressures
(Pergamon-Elsevier Science Ltd, 2020-04)
Mollusk shells can provide important information regarding environmental parameters. It is known that shell morphology is affected by both natural and anthropogenic factors. However, few studies have investigated alterations ...
Spatio-temporal trends and body size differences of OCPs and PCBs in Laeonereis culveri (Polychaeta: Nereididae) from Southwest Atlantic estuaries
(Pergamon-Elsevier Science Ltd, 2018-11)
Southwest Atlantic (SWA) estuaries have been historically impacted by industrial and agricultural activities that represent an important source of organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs). ...
Linking stable isotopes and biochemical responses in Balanus glandula under sewage influence
(Pergamon-Elsevier Science Ltd, 2018-02)
In the present study, we analyzed the influence of untreated sewage exposure on carbon (δ13C) and nitrogen (δ15N) isotopic composition and several biochemical responses in the barnacle Balanus glandula. The main objective ...
Blood cadmium and metallothionein concentrations in females of two sympatric pinnipeds species
(Pergamon-Elsevier Science Ltd, 2017-05-30)
Otaria flavescens (SASL) and Arctocephalus australis (SAFS) are endemic of South America. The aims were to assess Cd concentrations in red blood cells (RBC) and plasma from free living females of both species; and to ...
Short-term efficiency of epibenthic microbial mat components on phosphorus sorption
(Pergamon-Elsevier Science Ltd, 2020-08-03)
Microbial mats may be an alternative tool for phosphorus (P) remediation of eutrophic coastal waters. The main objective of this work was to determine the importance that the living and non-living components of the mats ...
Assessing environmental health using ecological indices for soft bottom in sewage-affected rocky shores: The case of the largest seaside resort of SW Atlantic
(Pergamon-Elsevier Science Ltd, 2017-02-15)
Efficient ecological indices can reflect the differences between impacted and nonimpacted sites, leading to significant variations at the contamination spatial scale. Here, we evaluated the spatial-temporal variability of ...
Spatial-temporal variations of a SW Atlantic macrobenthic community affected by a chronic anthropogenic disturbance
(Pergamon-Elsevier Science Ltd, 2020-07)
The effect of the chronic anthropogenic disturbance in a coastal area of the SW-Atlantic was tested through a multimetric-approach. This study integrates environmental variables, biotic indices of environmental quality, ...
Petroleum oil removal by immobilized bacterial cells on polyurethane foam under different temperature conditions
(Pergamon-Elsevier Science Ltd, 2017-05)
In this work, a mixed biofilm composed by Pseudomonas monteilii P26 and Gordonia sp. H19 was formed using polyurethane foam (PUF) as immobilization support, for crude oil removal from artificial sea water. Fresh immobilized ...
The boom-bust dynamic of the invader Boccardia proboscidea mediated by sewage discharge: The response of the intertidal epilithic community in the Southwest Atlantic
(Pergamon-Elsevier Science Ltd, 2021-03)
Biological invasions produce an invader population boom but are often followed by an invader population bust. The decrease of the invader abundance ends with the coexistence of native species and the invader or with repeated ...
