A species' life history is the pattern of life cycle processes, including growth, development, reproduction, and death. Life history traits, therefore, are traits that relate to the timing and …

- 8.1: What is life history?
For example, one could measure the distribution of life history traits such as maximum life span across an assemblage. Or one could measure functional traits such as maximum metabolic rate (in an animal) or maximum photosynthetic rate of a leaf (in a plant).
Learn how natural selection shapes organisms to optimize their survival and reproduction through life history traits, such as size, growth, maturation, and lifespan. See examples of life history diversity and trade-offs among species and how they evolve.
Feb 23, 2024 · Life history characteristics are traits that affect the life table of an organism, and can be imagined as various investments in growth, reproduction, and survivorship. The goal of life history theory is to understand the variation in such life history strategies.
Life History Characteristics. Life history characteristics, such as synchronized generations or life stages (perhaps dormant) that are not available for sampling (e.g., the seed bank or the nymphs of the 21-year cicada), can lead to apparently major changes in density.
The key to life history theory is that there are limited resources available, and focusing on only a few life history characteristics is necessary. Examples of some major life history characteristics include: Age at first reproductive event; Reproductive lifespan and ageing; Number and size of offspring
Life history theory explains the general features of life cycle, i.e., how fast the organism grows, at what age it matures, how long it lives, and how often it reproduces. The theory is central to evolutionary ecology, as it directly deals with natural selection, fitness, adaptation, and constraint.
