Many mammals, such as otters, live in close association with rivers and streams, feeding in them, or using them as a place of safety or means of escape from predators. The distinct adaptations that riparian mammals have evolved in order to live in these environments also handicap them for living elsewhere. They are therefore threatened by alterations to their environment. In recent years our rivers have become highly polluted, and with bankside modifications for agriculture and forestry, enhanced or decreased water flow, and use for recreation, they become less and less suitable for these highly specialized animals. This 1998 book looks at the habitat utilization, adaptation, feeding ecology and conservation status of a range of riparian mammals, and will give insights into the problems facing these fascinating animals, and how they might be overcome.
