Mammals foraging

System 20. aquatic plants—bentos, plankton, coastal aquatic plants (XII) aquatic animals including bottom sediment invertebrates, fishes, amphibians, mammals, vertebrates, their biological reactions and endemic diseases (VIII) aerosols, atmospheric air (31, 32)—foodstuffs, forages (XV). Human poisoning through consumption of fish and other aquatic foodstuffs with excessive bioaccumulation of pollutants is the most typical example of biogeochemical migration and its consequences. 

Interspecific chemical cues are also often mixtures. Mixtures of amino acids serve as feeding stimulants in fish. Among mammals, ferrets respond more to mixtures than to pure odors in their foraging responses. The mixtures are thought to contain more information (Apfelbach, 1973).

Aminocarb. Next to fenitrothion, aminocarb has been the insecticide used most extensively in forestry in Canada over the past decade. Application rates of up to 0.175 kg/ha have been found to have little or no impact on forest songbird populations or small mammal breeding activity, but do cause considerable knockdown of terrestrial arthropods, particularly at higher application rates (35, 36). Short-lived but fairly extensive honeybee mortality has been documented when aminocarb has been applied while active foraging was underway, but the overall colony vigor was not seriously effected (37 ). Aminocarb does not appear to cause bumble bee mortality at operational application rates, but does affect solitary bees ( 18).

All mammal species have different shaped teeth. Some of them have teeth that protrude from the mouth and cannot be hidden when the mouth is closed. These are called tusks and are usually used for foraging, fighting or manoeuvring, while teeth are used for tearing or masticating. 

All of these species are excellent climbers, but they also forage on the ground. These animals are efficient predators, feeding largely on squirrels, rabbits, hares, smaller mammals, grouse, partridge, and pheasant. 

Interesting chemotherapeutic possibilities are suggested by this knowledge that the iron-foraging of bacteria is very different from that of mammals. For information on the use of siderochromes as antidotes in iron poisoning, see Section 11.6.
