• Example of range distances (emphasizing a maximum distance) in Biology: the dispersal distance refers to seed dispersal by pollination, to natal dispersal, to breeding dispersal, to migration dispersal, etc. • Examples of spacing distances (emphasizing a minimum distance) in Biology: nearest-neighbor distance which an animal maintain, in
•We can build specialized distances that incorporate different types of information (abundance, trees, geographical locations, etc.) •We can visualize complex data as long as we know the distances between objects (observations, variables) •We can compute distances (correlations) between distances to compare them
