Occurrence of the Garter Snake, Thamnophis sirtalis, in the Great Plains and Rocky Mountains

"Occurrence of the Garter Snake, Thamnophis sirtalis, in the Great Plains and Rocky Mountains" by T. Paul Maslin and Henry S. Fitch dives into the ecology and distribution of the common garter snake (Thamnophis sirtalis) across two distinct geographic regions of North America: the Great Plains and the Rocky Mountains.

Here's a breakdown of the key areas explored in this research:

Focus Species: The study concentrates on the common garter snake (Thamnophis sirtalis), a widely distributed reptile species in North America.

Geographic Scope: The research specifically focuses on populations of Thamnophis sirtalis inhabiting the Great Plains and Rocky Mountains regions.

Key Content:

• Habitat Utilization: Maslin and Fitch likely examine the various habitat types utilized by garter snakes in these regions. This might involve:

  • Descriptions of preferred habitats within the Great Plains (grasslands, wetlands) and the Rocky Mountains (forests, rocky outcrops).
  • Analysis of how habitat features (vegetation, water availability) influence garter snake distribution and abundance.

• Adaptations: The study might explore adaptations that allow garter snakes to thrive in these diverse environments. This could include:

  • Physiological adaptations for surviving in cooler climates of the Rocky Mountains compared to the warmer Great Plains.
  • Behavioral adaptations for finding food and shelter in different habitat types.

• Distribution Patterns: The research likely analyzes the geographic distribution patterns of Thamnophis sirtalis across the Great Plains and Rocky Mountains. This might involve:

  • Creating maps that illustrate the range of garter snake populations in these regions.
  • Discussing factors influencing their distribution boundaries, such as climate, prey availability, and competition with other predators.

• Comparison Across Regions: The authors likely compare the ecology and behavior of garter snakes between the Great Plains and Rocky Mountains populations. This could reveal:

  • Variations in body size, coloration, or prey preferences due to adaptations to different environments.
  • Similarities in life history traits like reproduction or hibernation strategies.

Overall Significance: This study by Maslin and Fitch contributes to a broader understanding of the common garter snake's ecological diversity. By examining their occurrence in the Great Plains and Rocky Mountains, the research sheds light on how these snakes adapt to varying habitats and climates across their vast geographic range. This knowledge is valuable for herpetologists studying snake ecology and for conservation efforts aimed at protecting garter snake populations.
