- Field guideHow beavers build damsA beaver dam is a maintained, leaky barrier rather than a concrete wall. It reduces current and raises local water depth, helping create aquatic access and refuge; as flow finds gaps and materials shift, beavers add branches, sediment, and vegetation where construction cues are strongest.
- Field guideWhy mammals have whiskersA whisker is a lever seated in a specialized, nerve-rich follicle. Contact or fluid motion bends the shaft and stimulates receptors at its base; the nervous system combines that signal with the whisker’s position and the animal’s own movement to infer what is nearby.
- Field guideKeystone species and ecosystem engineersA keystone species has effects on community structure that are large relative to its abundance. An ecosystem engineer changes the physical environment in ways that alter resources for other organisms. The concepts overlap in beavers, but they are not synonyms.
- Field guideReading burrows, dens, and lodgesAn opening or mound is only the first clue. Its construction, position in the landscape, tracks, food remains, and changes over time make a stronger case for who built or uses it.
