What is polyandry?
Polyandry occurs when females mate with multiple males within a given breeding period.
What is life history in ecology?
Life history refers to how an organism allocates its time and energy between growth and reproduction.
What are the two general models of reproductive strategies?
One model involves organisms with low survival rates investing early in reproduction, while the other involves those with higher survival rates investing in growth and delayed reproduction.
What are sneaker males in bluegill sunfish?
Sneaker males mature earlier and invest more in reproduction than growth, sneaking fertilizations while parental males are courting females.
What is monogamy in ecological terms?
Monogamy refers to having one mate, which can be for life or for a specific breeding bout.
What is iteroparity?
Iteroparity is when an organism has multiple reproductive events over time, such as birds mating every spring.
What do female mimic males do in bluegill sunfish?
Female mimic males behave like females to sneak fertilizations while parental males are distracted by courting actual females.
What is polygyny?
Polygyny is a mating system where one male mates with multiple females within a breeding bout.
What is parental care in ecology?
Parental care is any resource offered to the young after fertilization, including brooding, provisioning food, and ensuring safety.
What are parental males in bluegill sunfish?
Parental males are those that allocate energy toward growth initially, mature later, build nests, and provide care for their offspring.
How can organisms trade off between survival and reproduction?
Organisms can choose to reproduce more and not survive as long, or survive longer and reproduce more slowly.
What is semelparity?
Semelparity is when an organism has a single massive reproductive event, such as annual plants or Pacific salmon.
How do parental males recognize their fertilized eggs?
Parental males can recognize their eggs through chemical cues and may eat eggs that are not fertilized by them.
How is promiscuity defined in mating systems?
Promiscuity involves individuals having multiple random mates within a given period of time.
What are alternative reproductive tactics?
Alternative reproductive tactics are different behaviors within the same species and sex that individuals use to gain access to mates.
What is frequency dependent selection?
Frequency dependent selection is a process where the success of a reproductive tactic depends on its frequency in the population.
