Study Notes
Predator-Prey Interactions
- Predator-prey interactions are built around the concept of coevolution, where the fitness of two different species is tightly linked, and they evolve in response to evolutionary changes in each other.
- Coevolution leads to a constant adaptation of predators and prey to survive and outcompete each other.
Predator Adaptations
- Camouflage is a common adaptation used by predators, where they use body shape and coloration to blend in with their environment.
- Example: polar bears use their white fur to blend in with snowy environments, making it easier to capture prey.
Prey Adaptations
- Camouflage is also used by prey to avoid predators, by blending in with their environment.
- Example: deer use their brown fur and spots to blend in with wooded environments.
- Communication techniques are used by prey to warn each other of predators, such as:
- Vervet monkeys using vocalized signals for different types of predators.
- Honeybees using vibrations to warn others in the hive.
- Prairie dogs stomping their feet to warn others of predators.
- Offensive techniques are used by prey to protect themselves, such as:
- Skunks spraying chemicals to ward off predators.
- Cactus plants having spikes to prevent being eaten by predators.
- Warning coloration is used by prey to signal to predators that they are toxic or dangerous, such as:
- The strawberry poison dart frog's bright red color to warn predators that it is toxic.
- Mimicry is used by prey to resemble another species that is toxic or dangerous to predators, such as:
- Batesian mimicry, where a harmless organism mimics the warning coloration of a harmful species.
Predator vs. Prey
- Predator-prey interactions are a key component of the structure of ecosystems.
- Predators are organisms that capture and eat other organisms, while prey are the organisms being captured and eaten.
- Types of predators can include both carnivores and herbivores.
- Types of prey can include both animals and plants.
Examples of Predator-Prey Interactions
- Lion and zebra: the lion is a carnivorous predator, while the zebra is the prey.
- Zebra and grass: the zebra is an herbivorous predator, while the grass is the prey.
- Polar bear and prey: the polar bear uses camouflage to capture prey in the snowy environment.
