Effects of elevated salinity on Cuban treefrog Osteopilus septontrionalis aldosterone levels, growth, and development
ABSTRACT Amphibians are increasingly challenged with salinization due to factors such as elevated sea level associated with climate change, the use of road salts, and lowering of water tables. Aldosterone is a steroid hormone that is produced by the adrenal cortex and is involved in osmotic regulation and may play an important role in amphibian acclimation to elevated salinity. We studied the effects of salinity on growth, development, and aldosterone levels in Cuban treefrog (Osteopilus septentrionalis) tadpoles. Gosner stage, growth rates, and aldosterone levels were determined for tadpoles among three salinity treatments (1.0, 2.5, and 3.5 ppt) over a six-week period. It appears that Cuban treefrog tadpoles have the ability to respond to high salt levels with decreased aldosterone secretion; however, in order to survive high salt concentrations, trade-offs in growth and development must occur to regulate osmotic functions.
期刊介绍：
Marine and Freshwater Behaviour and Physiology is devoted to the publication of papers covering field and laboratory research into all aspects of the behaviour and physiology of all marine and freshwater animals within the contexts of ecology, evolution and conservation.
As the living resources of the world’s oceans, rivers and lakes are attracting increasing attention as food sources for humans and for their role in global ecology, the journal will also publish the results of research in the areas of fisheries biology and technology where the behaviour and physiology described have clear links to the contexts mentioned above.
The journal will accept for publication Research Articles, Reviews, Rapid Communications and Technical Notes (see Instructions for authors for details). In addition, Editorials, Opinions and Book Reviews (invited and suggested) will also occasionally be published. Suggestions to the Editor-In-Chief for Special Issues are encouraged and will be considered on an ad hoc basis.
With the goal of supporting early career researchers, the journal particularly invites submissions from graduate students and post-doctoral researchers. In addition to recognising the time constraints and logistical limitations their research often faces, and their particular need for a prompt review process, accepted articles by such researchers will be given prominence within the journal (see Instructions for authors for details).
