Understanding $r$-Selected Species Characteristics

The question asks to identify a trait that is NOT typical of $r$-selected species. $r$-selected species are those that have a high growth rate and reproduce quickly, often in unstable environments.

$r$-Selected Species Traits

• Large number of offspring: They produce many young to ensure some survive.
• Early sexual maturity: They reach reproductive age quickly.
• High juvenile mortality: Many young individuals do not survive to adulthood.
• Minimal or no parental care: Parents typically provide little to no care for their offspring after birth/hatching.
• Short lifespans.
• Small body size.

Differentiating from $K$-Selected Species

In contrast, $K$-selected species tend to live in stable environments, invest more resources in fewer offspring, and exhibit high parental care. This increased parental investment helps ensure the survival of the limited offspring.

Identifying the Incorrect Characteristic

Based on the typical characteristics:

• Early sexual maturity is a trait of $r$-selected species.
• High juvenile mortality is a trait of $r$-selected species.
• Large number of offspring is a trait of $r$-selected species.
• High parental care is characteristic of $K$-selected species, not $r$-selected species.

Therefore, the characteristic NOT associated with $r$-selected species is high parental care.
