The location (gills, oro-branchial cavity or elsewhere) and orientation (external (water) or
internal (blood) sensing) of the receptors involved in reflex changes in each of the different …

The hypoxic ventilatory response is arguably the single most important physiological
response accompanying the exposure of fish to lowered ambient P o 2. Increases in …

Respirometry is a robust method for measurement of oxygen uptake as a proxy for metabolic
rate in fishes, and how species with bimodal respiration might meet their demands from …

The reasons why metabolic rate (B) scales allometrically with body mass (M) remain hotly
debated. The field is dominated by correlational analyses of the relationship between B and …

Competition is a ubiquitous structuring force across systems, but different fields emphasize
the role of different types of competition. In benthic marine environments, where some of the …

We examined the hypothesis that Trichogaster microlepis, a fish with an accessory air-
breathing organ, uses a compensatory strategy involving changes in both behavior and …

Hypoxic water and episodic air exposure are potentially life-threatening conditions that fish
in tropical regions can face during the dry season. This study investigated the air-breathing …

Anthropogenic sources of environmental pollution are ever‐increasing as urban areas
expand and more chemical compounds are used in daily life. The stimulant caffeine is one …

Air-breathing fish of the Anabantoidei group meet their metabolic requirements for oxygen
through both aerial and aquatic gas exchange. Siamese fighting fish Betta splendens are …

It has long been hypothesised that there is a functional correlation between brain size and
metabolic rate in vertebrates. The present study tested this hypothesis in wild-caught adult …
