Immediately following a hurricane, when environmental conditions are most extreme, they exhibit low densities.
The dominant issue in the hurricane domain - disaster relief - remains constant because there is no obvious advocacy coalition in the hurricane domain.
Degrees of freedom for models excluding the interaction term were 1 (time since disturbance), 1 (hurricane) and 25 (error).
Degrees of freedom for models including the interaction term were 1 (interaction), 1 (time since disturbance), 1 (hurricane) and 24 (error).
Apparently these factors combine to limit both the chemicals that respond to hurricane disturbance, and the duration of that response.
A significant effect of time since disturbance would indicate a consistent linear response to elapsed time following a hurricane, regardless of identity.
Potassium, nitrate and ammonium concentrations and fluxes showed dramatic responses to hurricane disturbance.
But often the natural does great harm - disease, pestilence, floods, hurricanes, fire, landslides, and the like can cause massive loss of human life.
