The schedule of an individual's life-age at maturiy, number of offspring, life span
A consequence of devoting limited time, energy, or materials to one structure, function, or behavior at the expence of another
The division of limited time, energy, or materials among competing functions or requiremtnts
Acquisition of reproductive function, or the age at which this occurs
The number of episodes of reproduction in an individual's
The number of offspring produced per reproductive episodes
The life span of an individual
A growth pattern in which an individual continues to grow only until it reaches maturity
A growth pattern in which an individual continues to grow, usually at a decreasign rate, after maturity.
Death as part of a semelparous life history
A life history characterized by a single, terminal reproductive episode.
A life history characterized by multiple reproductive episodes
Reducing the risk of mortality or reproductive failure in a variable environment by adopting an intermediate strategy or several alternative strategies simultaneously, or by spreading on's risk over time and space
Gradual deterioration of physiological function with age, leading to increased probability of death, aging.
A physiologically inactive state, such as hibernation, diapause or seed dormany, usually assuemd when conditions do not allow the organism to function normally
A state of winer dormancy involvign lowered body temperature and metabolism
Temporary interruption of development or physiological function, usually associated with a period of unfavorable environmental conditions
An aspected of the environment that the organism uses as a cue for behavior, but which does not directly affect the organism's fitness
An aspect of the environment that directly affects the fitness of an organism
the length of the daylight period in a 24 hour day
A theoretical concept that seeks to explain foraging behavior in terms of the fitness costs and benefits of each possible alternatvie behavior
central place foraging
foraging behavior in which acquired food is brought to a central place, such as a nest with young
foraging behavior that is influenced by the presence of predators or risk of predation
