Excerpt from Systematics of the Leptodactylid Frog Genus Telmatobius in the Andes of Northern PeruThe physiography of northern Peru is dominated by the Cordillera Occidental, the Cordillera Central, and the Huancabamba Depression. The Huancabamba Depression is a system of low arid valleys (ca. 1000 - 2000 m above sea level) and isolated mountain ranges (including the Cordillera Colan and Cordillera Huancabamba) that separate the northern and c...

The two volumes of John Wiens' Ecology of Bird Communities have applications and importance to the whole field of ecology. The books contain a detailed synthesis of our current understanding of the patterns of organisation of bird communities and of the factors that may determine them, drawing from studies from all over the world. By emphasizing how proper logic and methods have or have not been followed and how different viewpoints have devel...

A major study of avian community ecology.

In this volume, eleven leading systematists provide an overview of recent advances and controversies in morphological phylogenetics. They summarize new methodological developments—including approaches for analyzing ontogenetic data, fossils, morphometric characters, intraspecific variation, and hybrid taxa—and review published studies to evaluate how morphological phylogenetics has actually been practiced. They also discuss the relationship be...
