Study Notes

Niche

  • Represents the role of an organism within its ecosystem.
  • Includes how it acquires food, its diet, type of shelter, activity patterns, and its predators.

Generalist Species

  • Possess a broad niche, allowing them to thrive in diverse environments.
  • Capable of consuming a variety of foods and tolerating a wide range of environmental changes.
  • Examples include rats, mice, raccoons, cardinals, cockroaches, and white-tailed deer.
  • Better adaptability leads to increased longevity and resilience against unexpected changes.

Specialist Species

  • Characterized by a narrow niche, often restricted to specific habitats and limited food sources.
  • Generally intolerant of varying climate and environmental conditions, making adaptation difficult.
  • Examples include river otters, woodpeckers, pandas, tiger salamanders, and spotted owls.
  • Higher risk of extinction, especially when environmental conditions shift.

Comparisons

  • Generalists can adapt more effectively to environmental changes than specialists.
  • Generalists typically exhibit greater longevity due to their ability to handle unforeseen risks.
  • Specialists experience less competition within their niche but face higher extinction risks under changing conditions.
