“…Additionally, all the mentioned factors can even alter the bioaccumulation profiles and the levels of pollutants in tissues of exposed organisms (Stanic et al, 2006;Vidal-Liñán et al, 2010). It is possible to sustain that modifications in biomarker levels can also be due to the natural physiological cycles of sampled organisms, rather than being indicators of exposure to chemical pollution (Sheehan and Power, 1999;Vidal-Liñán et al, 2010). Indeed, the distinction between periods (which were defined according to the physiological and reproductive state) is visible in the overall biomarker profile of the three subpopulations.…”

“…Among these, health condition, sex, age, nutritional status/food availability, reproductive phase, metabolic activity, population density, migratory behavior, and environmental factors (e.g., season, and temperature) can alter the physiology of test organisms, thus compromising the effectiveness of biomarker use in environmental analysis, namely for the detection of contamination (van der Oost et al, 2003;Napierska et al, 2009). Additionally, all the mentioned factors can even alter the bioaccumulation profiles and the levels of pollutants in tissues of exposed organisms (Stanic et al, 2006;Vidal-Liñán et al, 2010).

“…Both CAT and GSTs activities were substantially higher during May and June. Several studies show that CAT activity in marine organisms may be modulated by seasonal variations, including reproductive cycles and nutritional status (Regoli, 1998;Sheehan and Power, 1999;Vidal et al, 2002;Leiniö and Lehtonen, 2005;Vidal-Liñán et al, 2010). Catalase is mainly located in a specific intracellular organelle of the liver, the peroxisome, whose function is related to metabolism of fatty acids (Huggett et al, 1992), with release of H 2 O 2 as by-product.…”

Sardina pilchardus is a marine species common in the North Atlantic Ocean, and is subjected to diffuse anthropogenic chemical contamination and seasonal fluctuations in biotic and abiotic parameters that may alter its physiology and condition. Biological material is easily available through commercial fisheries, which could facilitate its use as a bioindicator species. The aim of the present work was to address its potential inclusion in biomonitoring studies, considering a combinatory approach through the use of enzymatic biomarkers and somatic indices, by assessing spatial and temporal patterns in a metapopulation along the west coast of Portugal. Our results showed significant variability of the biochemical and physiological profile of the fish, mainly concordant between sampling sites. Large differences for most markers were found across periods of the year, showing the importance of seasonality, which was mostly related to the reproductive cycle. Hence, environmental scientists should acknowledge seasonality as a strong driving force for physiological adaptations, influencing biochemical markers that are normally used to identify effects of chemical contamination. The here-obtained set of data suggests that S. pilchardus may be successfully included in oceanic biomonitoring studies, when one considers that the contribution of seasonal factors may exceed the influence of eventual anthropogenic contamination.

This work presents the study of the effects of acute exposure to various concentrations of copper from 0.03 to 0.59 mol⋅L −1 on the metabolic activities (nitrogen and phosphorus), protein levels, catalase (CAT) enzyme activities, and the biological response malondialdehyde (MDA) in the mollusks Perna perna and Mytilus galloprovincialis. The concentrations above 0.88 mol⋅L −1 have proven to be lethal to P. perna. The results show slight disturbances of metabolism as a result of pollutant and a significant correlation between metal contamination and ammonia nitrogen levels, resulting in an increase in the latter after 48 h of M. galloprovincialis exposure to 0.59 mol⋅L −1 of copper concentrations. CAT was rapidly induced even by low concentrations of copper; MDA was increased only with low concentrations of copper in P. perna.

“…Stress leads to a cascade of molecular and physiological reactions that can be easily detected (Livingstone 1993), and environmental stress is a possible cause of an excess of free radical production. Therefore, some antioxidant enzymes such as catalase, glutathione peroxidase, and glutathione reductase have been proposed as biological indicators of stress in aquatic organisms (Box et al 2009, An and Choi 2010, Vidal-Linan et al 2010, Sureda et al 2011. In this study, the use of a battery of biomarkers has been useful for indicating different responses in the two crabs.…”

Summary:Markers of oxidative stress in the hepatopancreas and carotenoid and vitamin E content in the carapace of the invasive crab Percnon gibbesi and the native crab Pachygrapsus marmoratus were compared as indicators of their physiological condition and environmental adaptation. Crabs similar in size were collected from coastal waters of Portals Vells (Mallorca Island, Spain; 39°28'18.79"N, 2°28'19.63"E) at <1 m depth. Vitamin E levels were significantly higher in P. mar moratus than in P. gibbesi, whereas all carotenoid concentrations, except astaxanthin, were significantly higher in P. gibbesi. Catalase, glutathione peroxidase and glutathione reductase activities were significantly greater in P. marmoratus. Malondialdehyde concentration, a marker of lipid peroxidation, was higher in the hepatopancreas of P. gibbesi. The differences in carotenoid and vitamin E contents and in the antioxidant enzyme activities are a reflection of the different physiological activity of the two species and may suggest that P. gibbesi is not a potential competitor for the native crab P. marmoratus.Keywords: antioxidants; carotenoids; alien species; Mediterranean Sea; oxidative stress; vitamin E. Adaptación fisiológica a los hábitats del Mediterráneo del cangrejo nativo Pachygrapsus marmoratus y el invasivoPercnon gibbesi (Crustacea: Decapoda) Resumen: Se evaluaron marcadores de estrés oxidativo en el hepatopáncreas, y el contenido de carotenoides y de vitamina E en el caparazón del cangrejo invasivo Percnon gibbesi y del cangrejo nativo Pachygrapsus marmoratus como indicadores de su estado fisiológico y su adaptación al ambiente. Cangrejos de tamaño similar se capturaron en las aguas costeras de Portals Vells (Mallorca, España; 39°28'18.79"N, 2°28'19.63"E) a <1 metro de profundidad. Los niveles de vitamina E fueron significativamente mayores en P. marmoratus que en P. gibbesi, mientras que todas las concentraciones de carotenoides, excepto la astaxantina, fueron significativamente mayores en P. gibbesi. Las actividades enzimáticas de la catalasa, glutatión peroxidasa y glutatión reductasa fueron significativamente mayores en P. marmoratus. La concentración de malondialdehí-do, como marcador de peroxidación lipídica, fue más elevada en el hepatopáncreas de P. gibbesi. Las diferencias observadas en los niveles de carotenoides y vitamina E y en las actividades de las enzimas antioxidantes son un reflejo de la diferente actividad fisiológica de ambas especies, lo que puede sugerir que P. gibbesi no sea un competidor potencial para el cangrejo autóctono P. marmoratus.
