Natural History of the Salamander, Aneides hardii

Here's a summary of "Natural History of the Salamander, Aneides hardii" by Richard F. Johnston and G. A. Schad:

Focus Species: This book dives into the natural history of the Sacramento Mountains Salamander (Aneides hardii), a lungless amphibian found in a specific region of New Mexico.

Content:

• Habitat and Distribution: The book focuses on the Sacramento Mountains in New Mexico, detailing the preferred habitat of Aneides hardii. This likely includes:

  • Specific elevation range where these salamanders are found.
  • Description of the habitat characteristics, such as forest type, moisture levels, and presence of hiding places (rocks, logs).
  • Potential distribution range of Aneides hardii within the Sacramento Mountains.

• Physical Description: Johnston and Schad likely provide a detailed description of the Aneides hardii salamander, including:

  • Size and body shape
  • Coloration patterns and variations
  • Unique morphological features

• Life History: The book explores the life cycle of Aneides hardii, likely covering aspects like:

  • Reproduction - Mating behavior, egg-laying habits, development of larvae (if aquatic) and metamorphosis to adulthood.
  • Growth and development - Growth rates, age at maturity, and lifespan estimates.

• Behavior: The authors likely examine the behavior patterns of Aneides hardii, including:

  • Activity cycles (diurnal, nocturnal)
  • Shelter-seeking behavior
  • Feeding strategies and prey preferences (invertebrates like insects)
  • Potential anti-predator adaptations

• Physiology and Adaptations: The book might discuss physiological adaptations of Aneides hardii that allow them to thrive in their mountain environment, such as:

  • Adaptations for living in a cool, moist habitat
  • Potential role of lunglessness in their respiratory system

• Comparison with Other Species: The authors might compare Aneides hardii to related salamander species to highlight unique characteristics or evolutionary relationships.

Overall Significance: This book by Johnston and Schad offers valuable information on the Sacramento Mountains Salamander. Understanding their specific habitat needs, life cycle, behavior, and adaptations is crucial for their conservation efforts. The book likely serves as a reference for researchers and biologists studying these salamanders and the ecosystem they inhabit.

Additional Notes:

• The book might include information on potential threats faced by Aneides hardii, such as habitat degradation or climate change.
• If published before widespread DNA analysis in taxonomy, the classification might rely on morphological characteristics.
