Section 55.5 described two studies of the effects of corridors on metapopulation dynamics—one on tiny arthropods with limited dispersal abilities (see Figure 55.12) and another on birds of tropical forests in Mexico (see p. 1162). Given the differences in size and mobility between tiny, wingless arthropods and forest birds, is it possible to come up with a general definition of a corridor? How could an investigator conduct a single experiment to determine the effects of corridors on multiple organisms that differ widely in size and mobility? Is it important to consider more than one group of organisms in trying to understand the effects of corridors in fragmented habitats?
