"A Distributional Study of the Amphibians of the Isthmus of Tehuantepec, México", published in 1960 by William Edward Duellman, focuses on the geographic distribution of amphibian species in the Isthmus of Tehuantepec, Mexico. This region holds significance because it acts as a land bridge connecting North and Central America.
Here's a breakdown of the book's key points:
- Geographic Focus: The study specifically examines the amphibian fauna (frog, toad, salamander) of the Isthmus of Tehuantepec.
- Content:
- Provides detailed descriptions of the Isthmus's geography, including its physiography, climate, and vegetation across different zones (Gulf Lowlands, Central Ridges, Pacific Coastal Plain).
- Analyzes the composition and ecology of the amphibian fauna in various habitats.
- Discusses the distribution patterns of amphibian species across the Isthmus.
- Offers explanations for how these distribution patterns came to be.
- Includes a species-by-species account with details on their distribution.
- Overall Significance: This book contributes to the understanding of amphibian biogeography in southern Mexico and Central America. It sheds light on the factors influencing amphibian distribution and the historical events that shaped current patterns.
If you're interested in the specific amphibian species found in the Isthmus or the ecological details of their habitats, you'll find that information within the book as well.
