Study Notes

Thermoregulation in Animals

  • Some animals bathe to cool down
  • Flying insects, such as bees, use shivering to warm up before taking flight
  • Adjusting metabolic heat production is a way for animals to regulate body temperature

Behavioral Adaptations

  • Some animals, like hummingbirds, enter a state of inactivity, such as seeking shelter, during extreme periods of weather or when food is scarce
  • Inactivity helps animals conserve energy and survive during harsh conditions

Communication in Animals

  • Pheromones are chemical substances released by an individual to affect other individuals of the same species
  • Pheromones are used for communication, such as to bring about mating or other behaviors

Territorial Behavior

  • Territories are used for feeding, mating, and rearing young
  • Territories are fixed in location and help animals defend their resources and space
