| Conceptual and mathematical models identify the conditions under which annual semelparity has a selective advantage over perennial iteroparity, where semelparous and iteroparous life histories are discrete alternatives. |
| In all species of Pacific salmon, the mature individuals die within a few days or weeks of spawning, a trait known as semelparity. |
| Semelparity and microcohorts spawning throughout the year in different regions are important components of their life strategy. |
| Although some of our detailed predictions might depend on our specific assumptions, such as semelparity, tradeoffs between current and future reproduction are probably universal even in iteroparous species like humans. |
| American Shad show a latitudinal gradient between semelparity and iteroparity throughout its range. |
| Called semelparity, this single blowout of procreation also shows up in organisms from salmon to garden squash vines. |
