...Koa N. Webster; Terence J. Dawson SUMMARY We examined the structure–function relationships that underlie the aerobic capacities of marsupial mammals that hop. Marsupials have relatively low basal metabolic rates (BMR) and historically were seen as ‘low energy’ mammals. However, the red kangaroo...

..., NKCC1. However, ileal secretion in the brushtail possum, a marsupial, involves a fundamentally different process, since NKCC1 expression is low in this tissue and the secretagogue-induced short circuit current ( I sc )is insensitive to bumetanide. In view of these differences we have investigated...
