- Describimos la cantidad de lluvia y transcolación durante veinte años (1988-2008), incluyendo varios periodos de sequías, huracanes y lluvias intensas. La composición de nutrientes en la lluvia y transcolación fueron medidos semanalmente durante quince años (1988-2002), incluyendo los periodos de huracanes y sequías. Las entradas anuales de K, Ca, Mg, Cl, Na y SO4- S fueron similares a las presentadas para otros bosques tropicales influenciados por la brisa marina. La cantidad de nitrógeno que llega con la lluvia es comparativamente baja y refleja el aislamiento relativo de zonas urbanas...AuthorsTamara Heartsill Scalley, Carlos R.
