We used a perfused gill preparation from dogfish to investigate the origin of low branchial
permeability to urea. Urea permeability (14C-urea) was measured simultaneously with …

There are large changes in gill function during development associated with ionoregulation
and gas exchange in both larval and air-breathing fish. Physiological studies of larvae …

We have explored the molecular and physiological responses of the euryhaline killifish
Fundulus heteroclitus to transfer from brackish water (10% seawater) to 100% seawater for …

The vulnerability of fish embryos and larvae to environmental factors is often attributed to a
lack of adult-like organ systems (gills) and thus insufficient homeostatic capacity. However …

Abstract Background The Mozambique tilapia Oreochromis mossambicus has the ability to
adapt to a broad range of environmental salinities and has long been used for investigating …

This review examines the mechanisms and regulation of ion and acid transfers across the
gills, focussing on freshwater fish. Apical ion-exchange mechanisms (ie, and exchange) are …

The crustacean gill is a multi-functional organ, and it is the site of a number of physiological
processes, including ion transport, which is the basis for hemolymph osmoregulation; acid …

The southern flounder is a euryhaline teleost that inhabits ocean, estuarine, and riverine
environments. We investigated the osmoregulatory strategy of juvenile flounder by …

The physiological mechanisms by which aquatic animals regulate the osmoconcentration of
their body fluids remain unclear despite many excellent studies of tissue and cell function …

Osmotic and Ionic Regulation: Cells and Animals not only fills a gap in the literature, but
delineates the new approaches, and findings that now define the field. Providing the first …
