Carol L. Boggs1,2* and David W. Weather drives population dynamics directly, through effects on vital rates, or indirectly, through effects on the Inouye1,3 populationÕs competitors, predators or prey and thence on vital rates. Indirect effects may include non-additive 1 Rocky Mountain Biological interactions with density dependence.
