K-Selected Species

Organisms with historical strategies characterized by producing few offspring

  • Low intrinsic growth rate: Slow sexual maturity + Narrow conditions + High competition

    • → Small/infrequent reproduction + high parental care

    • → Long lifespans

    • ~Specialists

      • Prone to Invasive species

    • ~Large

New cards

r-Selected Species

Organisms that produce large amounts of offspring

  • High intrinsic growth rate: Fast sexual maturity + Wide conditions + Low competition

    • → Abundant/frequent reproduction + little parental care

    • → Short lifespans

    • ~Generalists

      • Less vulnerable to Invasive species or disturbed conditions

    •  ~Small

Species are either K-Selected or r-Selected (T/F)

False— many have mixed traits

Biotic Potential

Ideal conditions where there are unlimited resources allows every population has a maximum potential for growth (maximum reproductive rate)

  • They utilize a range of reproductive strategies in nature

Population Growth Rate (Intrinsic Growth Rate) Formula

[(Population at End - Population at Start) / Population at Start] x 100
