Q

True Predator

A
  • Kill prey immediately
  • consume multiple prey organisms
  • function as agents of mortality on their prey

Q

Herbivores

A
  • consume only part of a plant

- doesn’t cause mortality

Q

Parasitism/Parasitoids

A
  • feeds on host while it is alive

- generally the activity isn’t lethal over the short term

Q

“smarter prey” Hypothesis

A

Predators act as an agent of mortality. Prey that can evolve to reduce detection and capture by predators should have higher fitness. Thus, evolution should produce “smarter” more evasive prey.

16
Q

“smarter predator” Hypothesis

Study These Flashcards
A

Failure to capture prey reduces fitness in the predator. Thus, evolution should produce “smarter” more skilled predators.

17
Q

The Red Queen Hypothesis

Study These Flashcards
A

To avoid extinction they must evolve means of outsmarting one another just to stay where they are.

18
Q

Adaptations to avoid predation (can be energetically costly)

Study These Flashcards
A
  • Chemical defenses (secretions or poisons that deter predators)
  • cryptic coloration
  • mimicry
  • Batesian Mimicry
  • warning colors
  • armor
  • behavior
