(Choice A)
A mosquito population in Florida grew in size after a trait conferring insecticide resistance became more common in the population.
(Choice B)
A fungus-like oomycete that causes Sudden Oak Death spread widely in United States forests, killing trees that had no natural immunity to the pathogen.
(Choice C)
A brown marmorated stink bug population in the United States grew exponentially in the absence of natural predators, causing problems as an agricultural pest.
(Choice D)
A yellow starthistle population in California grew rapidly in grasslands where other species of plants with similar niche requirements had declined as a result of cattle grazing and drought.
