A scientist is studying several areas along an elevation gradient. Her study involves prescribed burns (purposefully set, low-intensity fires) in the different areas, followed by a comparison of the type and abundance of organisms that colonize them over the next ten years. What scale best describes her study?

The serotinous cones of the longleaf pine, Pinus palustris, depend on _____ to release their seeds.

The basic reproductive number (R0) of a disease is described by this equation         S=susceptible population     β=host transmission rate     α=disease induced death rate     d=susceptible host death rate     ν=recovery rate of infected individual Based on the above equation and what you know about evolution, you would expect diseases to evolve to be [a1] transmissible, [a2] quickly recoverable, and [a3] deadly

What is an example of a +/− interaction?

How do corals react when water temperatures are too high?

A fisheries biologist tells you she is studying a cohort of salmon returning to their birth river. What can you infer about those salmon?

Lions, leopards, and other large terrestrial predators generally maintain well-defined territories. What kind of dispersion pattern would you expect this to produce?

Many species of birds form large flocks. What dispersion pattern describes this behavior?

Given the formula: The rate of population growth approaches zero as [ans1].  Graphed, a population growing as described by this equation would create a line that is roughly [ans2].  

r-selected species tend to have type III survivorship curves.
