Life history pattern
WebSimilar patterns of life-history allocation have been recorded in related species (Reznick et al. 1992). But it is particularly the transplant experiments, both the initial Aripo introduction by Endler in 1976 (as above), and a later one (1981) in the El Cedro drainage (part of the Guanapo River) by Reznick (see Table 3.2 and Fig. 5.1 ), that ... WebThe initial trade-off between seed number and seed size leads to different benefits or drawbacks in future life history traits such as seed dispersal, seedling survival, and seedling competitive success. Large seeds exhibit a higher likelihood of survival and stronger competitive advantage, but are few in number and unable to disperse long ...

WebLife History Patterns and Energy Budgets. Energy is required by all living organisms for their growth, maintenance, and reproduction; at the same time, energy is often a major limiting factor in determining an organism’s survival. Plants, for example, acquire energy from the sun via photosynthesis, but must expend this energy to grow ...
