Frequency of reproduction
| Semelparous / monotely | Breeding once per lifetime, or breeding only once then dying (Barnes et al., 2001). Organisms that only have one brood during their lifetime (Lincoln et al., 1998). | |
| Iteroparus / polytely 1) Breeding several times per lifetime. 2) Organisms that have repeated reproductive cycles (Lincoln et al., 1998). |
Annual episodic | Breeds every year but in one or more discrete periods initiated by some trigger (for example a lunar cycle). |
| Annual protracted | Breeds every year over an extended or drawn out period. | |
| < Biannual | Breeds less frequently than every two years. | |
| Biannual episodic | Breeds every second year but in one or more discrete periods initiated by some trigger (for example a lunar cycle). | |
| Biannual protracted | Breeds once every two years over an extended or drawn out period. | |
| Univoltine | One generation per year / annuals (Barnes et al., 2001). | |
| Multivoltine | Many generations per year (Barnes et al., 2001). | |
| Bivoltine | Two generations per year (Barnes et al., 2001). | |
| Semivoltine | One generation every two years (Barnes et al., 2001). | |
