BIO205H5 Lecture Notes - Pumpkinseed, Lepomis, Semelparity And Iteroparity
Document Summary
The organism reproduces shortly after birth and continues to reproduce every year, giving birth to numerous, large offspring. Physically no, also animals have limitations based on resources available, environment etc. Fecundity affects surviv of individual b/c resources for health etc. Douglass fir trees: higher number of cones = less growth in tree (skinnier annual rings) For european kestrels having a larger brood (more chicks) = less survival rate for chicks and smaller body mass. Semelparous - organism that reproduces only once in its lifetimre (ex. Invest more in reprodutcion from beginning b/c high mortality rate as adults: reproductive organ to rest of body size ratio is high. For pumpkin seed fish adult mortality is high so they start reproducing at a very young age and invest more into reproduction as compared to other fish that live longer. Feed on lichens which grow really slow so b/c of limited food supply population quickly declined.
