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 The present study reports a decrease in activity and sudden immobile state, known as thanatosis, the New Zealand endemic wrasse, Notolabrus celidotus . We observed tonic immobility immediately after wrasse collection field studies. Escape is primary defence of juvenile N. our observation suggests that thanatosis can be secondary strategy when first has failed. response occurred was manipulated by being removed from fishnet placed into buckets, allowing for conclusion may use...
Abstract Complex coastal habitats including seaweed and kelp forests are declining throughout the world due to impacts of ocean warming, development, overfishing, pollution. provide shelter, food, nesting, nursery sites, allowing for high biodiversity productivity that supports valuable economic, cultural, recreational services. From perspective prey, habitat‐forming macroalgae offer physical visual refuges reduce their risk predation. However, predators, this refuge availability presents a...
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...

Human activities, such as urbanization, can cause instability in the aquatic biota. This modify food resource availability, consequently shifting diet composition of fish. Because consumed by fish closely affects anatomy their digestive tract, it also alter intestinal coefficient. In this study, we analyzed composition, condition factor and coefficient Astyanax lineatus (Perugia, 1891) from two distinct habitats: a “degraded habitat” (Cabaça stream) reserve inside city perimeter “preserved...
