Proteinaceous phytochemicals can contain toxic epitopes that elicit defense responses for example gliaden and glutein peptides which cause celiac disease and other mucosal disorders (Tighe and Ciclitira, 1995 Van de Wal et al, 1999). The mucosal inflammation caused by feeding carnivorous Atlantic salmon diets with soybean meal decreases rates of nutrient absorption (Nordrum et al, 2000), whereas the detrimental influence of such diets is much less pronounced when fed to omnivorous fish, such as catfish and tilapia. 

When plants are consumed as food by herbivorous animals, the isotopic signatures in the plants are passed on to the consumers. Therefore, provided the isotopic signatures of C3 and C4 plants are known, determining the isotopie signatures in the tissues of herbivorous animals enables one to determine the relative amounts of C3 and C4 plants that the animals consumed as food, and to reconstruct their diets. Moreover, since carnivorous and omnivorous animals, including humans, feed on herbivorous animals as well as on plants, determining the isotopic signatures of the isotopes of carbon in tissues of ancient animals and humans makes it possible to elucidate the components of their diets. 

Red swamp crayfish (Procambarus clarkii) is a crustacean native to the South-central United States and Northern Mexico. It has been introduced in all continents except Australia and Antarctica, thus becoming the most widely distributed crayfish all over the world [52]. Procambarus clarkii is an omnivorous species, feeding mainly on... 

Plants are the base of the terrestrial food chain. The body tissue of herbivores feeding on these plants, and subsequently of omnivores and carnivores, is dependent on the isotopic composition of the plant material ingested, and therefore reflects the 813C values of either a C3 or C4 biome. The exact values are modified by metabolically induced fractionation as the food is digested and incorporated into different body tissues. At its simplest, it has been assumed... 

Omnivores excrete a more acidic urine than herbivores. Investigators have demonstrated increased urinary acid and calcium by feeding acid-producing chemicals. 

While the dog is a carnivore, it is able to adapt to an omnivorous diet. Requirements for dietary sources of energy, amino acids, glucose precursors, fatty acids, minerals, vitamins, and water have been established based on recommendations by the National Research Council (NRC, 1985). Adult beagles maintained in a laboratory environment function well with one feeding of standard laboratory chow per day. In safety assessment testing, however, some compounds may induce serious dietary deficiencies through induced loss of appetite, malabsorption, or vomiting, and, in these cases, it may be advisable to provide a dietary supplement.

The importance of transmission via the oral route has long been known in the case of susceptible omnivorous or insectivorous animals, which feed on vector insects and infected animal reservoirs (Dias, 2006 Neto et ah, 2000). Some authors consider the possibility that Carlos Chagas, in his first study together with Oswaldo Cruz, played an important role in the first demonstrated case of oral transmission of Chagas disease. Marmosets (C. penicillata) were placed in cages together with insects infected by the parasite, and also acquired the parasite. It is now known that transmission to these animals by insect bites is rare, and, at the time of the experiment, no entrance points were found on the animals thus, the hypothesis of ingestion of the insects by the marmosets cannot be discarded (Coura, 1997 Dias, 2006). 

The omnivorous leafroller (OLR) feeds on a wide variety of fruits, vegetables, and ornamentals. Vineyards use pheromone traps to monitor the OLR populations and determine when control methods are needed. 

The frequent occurrence of pheromonal mimics in plants is disturbing in view of the oft-presumed specificity of pheromonal chemicals. One might wonder whether their presence in plants has communicative significance for cockroaches. A defensive strategy based upon the possession of a sex pheromone mimic seems of dubious value to a plant unless the stimulation to sexual activity overrides or depresses feeding activities. Alternatively, attraction of omnivorous cockroaches might result in their destruction of competing plants or parasites.
