Here we report the widespread natural occurrence of a known antibiotic and antineoplastic compound, hydroxyurea in animals from many taxonomic groups. Hydroxyurea occurs in all the organisms we have examined including invertebrates (molluscs and crus

The urea-retaining strategy of elasmobranchs has shaped their biochemistry and physiology; from their metabolic organization to the structure of their membranes. It has also affected their capacity to live in freshwater. Although much new information

We examined some of the potential mechanisms lungfish (Protopterus dolloi) use to regulate cytochrome c oxidase (CCO), during metabolic depression. CCO activity was reduced by 67% in isolated liver mitochondria of estivating fish. This was likely acc

Only 5% of elasmobranch species live in freshwater (FW) compared to more than 40% of known teleost species. The factors affecting the poor penetration of elasmobranchs into FW environments are currently unknown, however, an important consideration ma

The African slender lungfish, Protopterus dolloi, is highly adapted to withstand periods of drought by secreting a mucous cocoon and estivating for periods of months to years. Estivation is similar to the diapause and hibernation of other animal spec

The potential importance of carbohydrates and amino acids as fuels during periods of fasting and aestivation in the African lungfish, Protopterus dolloi, were examined. No significant decreases in tissue glycogen levels were observed following 60 day

Smoltification involves morphological and physiological changes in the gills that prepare anadromous salmonids to osmoregulate efficiently in seawater. In a previous study, we found that different families of Atlantic salmon ( Salmo salar ) smolts va

The successful migration of euryhaline teleost fish from freshwater to seawater requires the upregulation of gill Na+-K+-ATPase, an ion transport enzyme located in the basolateral membrane (BLM) of gill chloride cells. Following 39 days of seawater e
