“…The tendency for excretion scaling to fall short of MTE predictions suggests that factors beyond metabolism, such as diet, play a role in regulating nutrient excretion (Wood , Uliano et al. ). We found that protein accounts for an average of 24% energy requirements at our overall coolest population to 56% at our overall warmest population, so some positive relationship between temperature and nitrogen excretion might still be expected.…”

Metabolism shapes the ecosystem role of organisms by dictating their energy demand and nutrient recycling potential. Metabolic theory (MTE) predicts consumer metabolic and recycling rates will rise with warming, especially if body size declines, but it ignores potential for adaptation. We measured metabolic and nutrient excretion rates of individuals from populations of a globally invasive fish that colonized sites spanning a wide temperature range (19-37°C) on two continents within the last 100 yr. Fish body size declined across our temperature gradient and MTE predicted large rises in population energy demand and nutrient recycling. However, we found that the allometry and temperature dependency of metabolism varied in a countergradient pattern with local temperature in a way that offset predictions of MTE. Scaling of nutrient excretion was more variable and did not track temperature. Our results suggest that adaptation can reduce the metabolic cost of warming, increasing the prospects for population persistence under extreme warming scenarios.

Structural and functional changes in the zebrafish (Danio rerio) skeletal muscle after cadmium exposure

et al. 2015

This report describes the alterations induced by an environmentally realistic concentration of cadmium in skeletal muscle fibre organization, composition, and function in the teleost zebrafish. Results demonstrate that the ion induces a significant quantitative and qualitative deterioration, disrupting sarcomeric pattern and altering glycoprotein composition. These events, together with a mitochondrial damage, result in a significant reduction in swimming performance. In conclusion, the evidence here collected indicate that in presence of an environmental cadmium contamination, important economic (yields in fisheries/aquaculture), consumer health (fish is an important source of proteins), and ecological (reduced fitness due to reduced swimming performance) consequences can be expected.

“…Diluted toxicological media reduce NP agglomeration and preserve more the nano-aspect of the particles, but comparative studies are required to ensure that organisms are largely unaffected by diluted media. Several organisms have been shown to tolerate diluted media (Uliano et al, 2010;Truong et al, 2012), where the NPs were more stable and the toxicity was shown to increase with the increased stability of the NPs (Truong et al, 2012;Römer et al, 2013). The concentrations of the diluted media should be as low as possible to prevent NP agglomeration, and generally at least lower than the CCC values of the NPs in the media used for ecotoxicological studies to avoid the rapid agglomeration and removal of the NP via DLA of the NPs.…”
