This is a list of invasive species in North America.A species is regarded as invasive if it has been introduced by human action to a location, area, or region where it did not previously occur naturally (i.e., is not a native species), becomes capable of establishing a breeding population in the new location without further intervention by humans, and becomes a pest in the new location ...
Pomacea diffusa is known as the spike-topped apple snail, because of its relatively raised spire. [1] It lacks a channeled suture, and overlaps in size with the Pomacea paludosa. [1] An egg cluster of Pomacea diffusa. The egg masses have an irregular honeycombed appearance, like those of Pomacea haustrum, but are smaller and have a tan to ...
The apple snail is a keystone species in Pantanal's ecosystem. When the wetlands are flooded once a year, the grass and other plants will eventually die and start to decay. During this process, decomposing microbes deplete the shallow water of all oxygen, suffocating larger decomposer
Pomacea haustrum were discovered in the late 1970s in Palm Beach County Florida, and have not spread appreciably in 30 years. [2] This is the only known area where this species is established in the United States. [2] The initial introduction in the United States was probably from aquarium release, aka "aquarium dumping".
