Multibiomarker studies are useful to evaluate the early warning signs of environmental degradation, and their unified responses often assessed through two common indexes, Integrated Biomarker Response (IBR) Biological Responses version 2 (IBRv2). The R package IBRtools allows users calculate both IBR IBRv2 while simultaneously incorporating all biomarkers under evaluation. includes functions for calculating indexes obtaining standardized values, as well a function radar chart creation three...
Predictions about global warming have raised interest in assessing whether ectothermic organisms will be able to adapt these changes. Understanding the physiological mechanisms and metabolic adjustment capacity of fish subjected heat stress can provide subsidies that may contribute decision-making relation ecosystems climate change. This study investigated antioxidant defence system energy metabolism carbohydrate protein responses gill, liver kidney tissues Psalidodon bifasciatus (Garavello...
Abstract Objective Ectothermic fish are directly affected by temperature changes in the environment. The aim of this study was to evaluate metabolic responses gills Yellowtail Lambari Astyanax lacustris under thermal stress. Methods To end, we used spectrophotometry biomarkers carbohydrate and protein metabolism, antioxidant defense, oxidative damage subjected low (15°C) high (31°C) temperatures, with control groups held at 23°C, for 2, 6, 12, 24, 48, 96 h. Result results showed that cold...
Abstract The southern region of Brazil is rich in hydric and biogeographic resources, contributing to the formation distinct ichthyofaunistic niches facilitating isolation some species. Despite great ecological importance, there are few cytogenetic molecular studies on ichthyofauna these basins. Therefore, specimens Ancistrus abilhoai Hemiancistrus fuliginosus were analyzed by combining mitochondrial markers. Cytogenetic analysis revealed a diploid number 2n = 48 for A. 56 H. Sites rDNA (by...
Abstract When exposed to high temperatures, changes in the respiration rate of fish occur, leading an increase formation reactive oxygen species. Thus, enzymatic and non-enzymatic responses antioxidant defense may be altered avoid cellular-level stress. Rhamdia voulezi is endemic species Iguaçu River Paraná, Brazil, great economic interest for farming. The aim this study was evaluate activity biomarkers (superoxide dismutase, catalase, glutathione peroxidase, S-transferase, reductase,...
