Chapter 25 - Populations and Ecosystems - Coggle Diagram

- - - - Disturbance usually produces R conditions. Resources are plentiful for those that remain, pioneers that produce many seeds quickly have an advantage, most seeds find suitable sites. Population density is low, spread of predators/pathogens low, threat isn't great. Biotic potential is limiting factor. Plants don't need defensive compounds, should grow quickly, flower early, and produce many small seeds. Typically annuals or small shrubby perennials.
    - - Almost every possible site is filled. After an individual dies, spot might become occupied by the seeds of a different species. It's advantageous to live for a long time, focus on antipredator defenses. Ability to use scarce resources are beneficial. Long lived conifers (douglas firs, redwoods) are examples.
