Allozymic Genetic Structure and Natural Habitat Fragmentation: Data for Five Species of Amazonian Forest Birds
Abstract I studied allozymic variation in five species of Amazonian birds at two geographic scales. At a local scale (all sites within 200 km of one another), I included samples from six sites, three within continuous forest and three in natural forest fragments thought to be several thousand years...
