The Dos Bocas dam in Puerto Rico.

Thumbnail
The Dos Bocas dam in Puerto Rico was constructed in 1942 to generate hydroelectric power. Dams in this region prevent the migration of shrimp and fish to areas upstream of the dam. As a result, compared to similar reaches of undammed streams, areas that are upstream of dammed rivers have higher amounts of organic and inorganic nutrients as well as altered invertebrate populations. Loss of migratory shrimp and fish upstream from dams alters basal resources and assemblages of invertebrate competitors and prey. This photograph originally appeared on the cover of Ecological Applications (16:1) in February of 2006.
