Abstract Effects of energetic limitations on the performance of sensory systems are generally
difficult to quantify. Weakly electric fishes provide an ideal model system to quantify the …

Many fishes perform quick and sudden swimming maneuvers known as fast-starts to escape
when threatened. In pulse-type weakly electric fishes these responses are accompanied by …

Environmental hypoxia has effected numerous and well‐documented anatomical,
physiological and behavioural adaptations in fishes. Comparatively little is known about …

Little of the vast body of literature devoted to the fishes of the Lake Victoria Basin (LVB) has
examined the region's mormyrids (African weakly electric fishes). These animals emit and …

Low dissolved oxygen (hypoxia) can severely limit fish performance, especially aerobically
expensive behaviours including swimming and acquisition of sensory information. Fishes …

In this study, the metabolic response and tolerance of cunner (a temperate wrasse species
capable of metabolic depression) to graded hypoxia (water O2 saturation 100–10%) was …

Hypoxic or oxygen-free zones are linked to large-scale mortalities of fauna in aquatic
environments. Studies investigating the hypoxia tolerance of fish are limited and focused on …

Hypoxia is a widespread environmental stressor that shapes fish physiology and
morphology. Plasticity in traits that improve oxygen uptake and delivery or reduce oxygen …

Abstract The Nile tilapia (Oreochromis niloticus) is widely farmed in tropical and subtropical
pond culture. O. niloticus is recognized as a species that is tolerant of hypoxic conditions, a …

Behavioural responses to changing environments affect community composition, so the
identification of associations between environmental gradients, behavioural traits and …
