  6. philopatric
    remaining in one's natal group or home range as an adult
  7. life history traits
    characteristics and developmental stages that influence rate of reproduction
  8. strategies
    behaviors or behavioral complexes that have been favored by natural selection because they're advantageous to the animals that perform them
  9. sympatric
    living in the same area; pertaining to two or more species whose habitats partly and largely overlap
  10. home range
    the total area exploited by an animal or social group, usually given for one year or for the entire lifetime of an animal

  21. reproductive strategies
    the complex behavioral patterns that contributes to individual reproductive success
  22. K-selected
    pertaining to k-selection, an adaptive strategy whereby individuals produce relatively few offspring, in whom they invest increased parental care
  23. r-selected
    pertaining to r-selection, an adaptive strategy that emphasizes relatively large numbers of offspring and reduced parental care
  24. sexual selection
    a type of natural selection that operates on only one sex within a species
  25. polyandry
    a mating system characterized by an association between a female and more than one male with whom she mates
  26. alloparenting
