The Tadpoles of Bufo cognatus Say

"The Tadpoles of Bufo cognatus Say" by Hobart M. Smith focuses on the larval stage, specifically the tadpoles, of the Great Plains toad (Bufo cognatus). Here's a breakdown of the key areas Smith explores in this short publication:

Target Species: The study concentrates solely on the tadpoles of the Great Plains toad (Bufo cognatus).

Focus: The book dives into the morphology (physical characteristics), ecology, and potentially the development of Bufo cognatus tadpoles.

Content:

• Morphology: Smith provides detailed descriptions of the physical features of Bufo cognatus tadpoles. This likely includes:

  • Body size and shape
  • Tail morphology (fin shape, musculature)
  • Mouthpart structures for feeding
  • Presence of gills and other adaptations for aquatic life
  • Eye placement and sensory organs

• Habitat and Ecology: The book might explore the preferred habitat types of Bufo cognatus tadpoles within the Great Plains region. This could involve:

  • Descriptions of breeding sites (ponds, temporary pools) favored by adult Great Plains toads for egg-laying.
  • Ecological factors influencing tadpole survival, such as water quality, presence of predators, and food availability.

• Development (Potential): The book might discuss the developmental stages of Bufo cognatus tadpoles, potentially including:

  • Transformation stages from newly hatched tadpoles to juveniles with developing limbs and lungs, leading to a terrestrial lifestyle.
  • Duration of the tadpole stage until metamorphosis.

• Comparison (Possible): Smith might compare the morphology or ecology of Bufo cognatus tadpoles to tadpoles of other toad species for highlighting similarities or adaptations specific to the Great Plains environment.

Overall Significance: This work by Smith contributes to a better understanding of the Great Plains toad's life cycle, specifically the tadpole stage. By detailing their morphology, habitat preferences, and potential development, the book provides valuable information for herpetologists (reptile and amphibian biologists) studying toad reproduction, ecology, and conservation.

Additional Notes:

• The book, likely published before widespread digital access, might reference relevant scientific publications for in-depth discussions on amphibian development or tadpole ecology.
• Illustrations or basic drawings of Bufo cognatus tadpoles might be included to aid in visualization.
