reproductive strategies

Cards (22)

  • mate recognition system
    the set of anatomical, behavioural and chemical clues that allow males and females of a species to recognise one another for the purpose of reproduction
  • What is parental care?
    A behavioral strategy for offspring survival
  • What is maternal behaviour?
    Behaviours by the mother to increase survival
  • What is the purpose of egg sitting in maternal behaviour?
    To keep eggs warm and safe from predators
  • How does suckling benefit offspring?
    It provides essential nutrients and bonding
  • What role does guarding their young play in maternal behaviour?
    It protects offspring from potential threats
  • Why is digging burrows significant in maternal behaviour?
    It creates a safe shelter for the young
  • What is the importance of nursing in maternal behaviour?
    Nursing provides vital nourishment to young
  • How does grooming contribute to maternal behaviour?
    It promotes hygiene and strengthens bonds
  • How does the development of altricial species compare to precocial species?
    Altricial species are less developed at birth and cannot survive alone, there is high parental investment until they mature
  • precocial animals are born with all their hair, feathers, or scales
  • What abilities do precocial animals have at birth?
    They can see, hear, and move around. they can immediately care for themselves
  • What is the major parental duty for precocial animals?
    • Keep young safe from predators
    • Watch over them as they eat
  • mating systems
    describe how animals find and choose their partners, and how they care for their offspring
  • monogamy
    when animals stay with one mate for a period of time (a breeding season, several seasons or their whole life)
  • monogamous pairs split parenting duties, such as caring for offspring and finding food
  • polygny
    when one male pairs with several females
  • in polygny, the males have no parental role over offspring
  • polyandry
    when one female pairs with many males
  • in polyandry the males share the parental role
  • promiscuity
    species mating with multiple partners, they dont form bonds
  • promiscuity increases genetic diversity, this can lead to healthier and more resilient population
