A matrix model for the population dynamics of Hyptis suaveolens, an annual weed
(2009-12-08)
Hyptis suaveolens is a neotropical annual weed that invades savanna agricultural systems. Although fire, grazing and soil disturbances have been proposed to cause its local dominance, these factors have not been experimentally ...
