NEARLY all food niaterials are in too complex and insoluble forms as they are consumed by either animals or man to be absorbed and assimilated. The specific purpose of digestion, therefore, is to convert these food substances into simple and soluble materials fit for absorption and assimilation. All animals except tlie most primitive types are provided with several highly specialized digestive ...

Roridula dentata and R. gorgonias, two South African plants that were formerly believed to be carnivorous, exhibit an extremely sticky exudate at the tips of secretory trichomes. Unlike the trapping mucilage of Droseraceae, it does not consist of acidic polysaccharides. The Roridula trapping glue was found to be a mutual solution of mainly dihydroxytriterpenoids, instead. All samples contain tw...

Experimental infections of Sminthopsis crassicaudata, the fat-tailed dunnart, a carnivorous marsupial widely distributed throughout the arid and semi-arid zones of Australia, show that this species can act as an intermediate host for Neospora caninum. In contrast to existing models that develop relatively few N. caninum tissue cysts, dunnarts offer a new animal model in which active neosporosis...

We describe the diet of Oligosarcus hepsetus, in the Santa Virgínia Unit of the Serra do Mar State Park. The Paraibuna and Grande rivers in the basin of the Paraíba do Sul River were sampled monthly from January to December 2004. The Alimentary Preference Degree and the frequency of occurrence indices were used to analyze the food items. The diets of Oligosarcus hepsetus in the two localities s...

Vertebrate gut microbiome often underpins the metabolic capability and provides many beneficial effects on their hosts. However, little was known about how host trophic level influences fish gut microbiota and metabolic activity. In this study, more than 985,000 quality-filtered sequences from 24 16S rRNA libraries were obtained and the results revealed distinct compositions and diversities of ...

MIGLIORINI, R. H., C. LINDER, J. L. MOURA, AND J. A. S. VEIGA. Gluconeogenesis in a carnivorous bird (black vulture). Am. J. Physiol. 225(6) : 1389-l 392. 1973.-Gluconeogenesis studies were carried out in the black vulture (Coragyps atratus), a carnivorous bird. The blood sugar levels of the black vulture were markedly resistant to 3 days of fasting. Also, no increase in plasma FFA levels was d...
