Document Summary
Plant life histories: semelparous plants (mono-carpic) flower once and die, but the timing is variable, the model angiosperm arabidopsis thalianacan be made to complete a life cycle in ~6 weeks http://www. mun. ca/biology/desmid/brian/ Amorphophallustitanumlives ~ 40 years and flowers just once. Poly-carpism: trees tend to have long life- spans and reproduce ~ yearly after a juvenile phase, some western canadian conifers like pseudotsuga menziesiican live upward of. 1000 years, potentially reproducing during most of them: the bristlecone pines (pinus, 3 or 4 species) are the oldest organisms on earth (ignoring clones), upwards of 4000 years old. Melissa fulton (jesson lab: among flowering plants animal pollination is most common, and considerable energy is investing in pollinator attraction and reward, wind-pollinated plants are crucial for humans, but are rarely too showy. Game theory: side-blotched lizards (uta stansburiana) are small iguanids native to california, and reach maturity in one year, there are three male throat-colour.
