Pharmaceuticals and personal care products (PPCPs) are found in measureable quantities
within the aquatic environment. Selective serotonin reuptake inhibitor (SSRI) …

The structural features of the fish gill necessary for oxygen uptake also favor undesirable,
passive movements of ions and water. Reversible gill remodeling is one solution to this …

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 …

Teleost fish have oxygen-sensitive neuroepithelial cells (NECs) in the gills that appear to
mediate physiological responses to hypoxia, but little is known about oxygen sensing in …

In response to varying environmental and physiological challenges, vertebrates have
evolved complex and often overlapping systems. These systems detect changes in …

Multiple anthropogenic activities present along coastal environments may affect the health
status of aquatic ecosystems. In this study, specimens of European sea bass (Dicentrarchus …

The study of breathing in fishes has featured prominently in Journal of Experimental Biology
(JEB), particularly during the latter half of the past century. Indeed, many of the seminal …

Acetylcholine (Ach) is the main neurotransmitter in the neuronal cholinergic system and also
works as a signaling molecule in non-neuronal cells and tissues. The diversity of signaling …

A highly sensitive oxygen (O 2) sensing mechanism is critical for the survival of all vertebrate
species. In fish, this requirement is fullfilled by the neuroepithelial cells (NECs) of the gill …

In fish, cells containing serotonin, ACh, catecholamines, NO, H 2 S, leu-5-enkephalin, met-5-
enkephalin and neuropeptide Y are found in the gill filaments and lamellae. Serotonin …
