High Altitude Tropical Biogeography provides research workers and academics with a comprehensive overview of the biogeography of high tropical mountains, covering the origin, ecology, and evolution of plants and animals of this unique ecological zone. The climate in the high altitude mountainregions of the tropics is cold, resulting in flora and fauna which more closely resemble their counterparts thousand of miles to the north or south than comparable species in the lowland jungles only a few thousand meters below. These ecological "islands", besides being very important to theeconomies of the tropics, pose interesting questions of physiological adaptation, biogeography, and evolutionary relationships. With contributions from twenty-four international specialists who have devoted years to the study of cold mountain tropics, this book describes some of the mostcharacteristic plant and animal components of the ecosystem. No other book of this scope and content exists on these tropical biotas.
