We review digestion and osmoregulation in the avian gut, with an emphasis on the ways
these different functions might interact to support or constrain each other and the ways they …

Flying vertebrates (birds and bats) are under selective pressure to reduce the size of the gut
and the mass of the digesta it carries. Compared with similar-sized nonflying mammals …

We measured the activities of eight digestive enzymes in four species of herbivorous and
carnivorous prickleback fishes and determined the effects of ontogeny, diet, and phylogeny …

Animals encountering nutritionally imbalanced foods should release elements in excess of
requirements in order to maintain overall homeostasis. Quantifying these excesses and …

Relative gut length, Zihler's index, and relative gut mass were measured in four species of
prickleback fishes and the effects of ontogeny, diet, and phylogeny on these gut dimensions …

We investigated whether nutrient limitations of primary producers act upward through food
webs only in terms of density effects or if there is a second pathway for nutrient limitation …

Failure to provision tissues with an appropriate balance of nutrients engenders fitness costs.
Maintaining nutrient balance can be achieved by adjusting the selection and consumption of …

The effects of feeding juvenile crossbred tilapias diets containing 30%(LP) and 48%(HP)
protein on the activity of intestinal brush border enzymes and on their growth performance …

The main objective of this study was to investigate mopane worm (Imbrasia belina) as a
protein source in the diet of Oreochromis mossambicus. One thousand five hundred O …

The arboreal marsupial monito del monte (genus Dromiciops, with two recognized species)
is a paradigmatic mammal. It is the sole living representative of the order Microbiotheria, the …
