Meat ant within a colony is typically favoured as it improves access to forage, as workers deliver most of their food to the nest that is closest to any site they forage in. At any size, a meat ant nest always has a possibility of dying out in any year, but the site may be reoccupied by another colony. Hence, nests can be very old as suggested in one study. Some nests may never be reoccupied for unknown reasons. The regrowth of vegetation which shades the nest, soil damage or even a disease may wipe out a colony and leave the nest
Correct name orthographical variants. The zoological equivalent of "correct name" is "valid name". Different taxonomic placements may well lead to different correct names. For example, the earliest name for the fastest growing tree in the world is "Adenanthera falcataria" L. The "L." stands for "Linnaeus" who first validly published the name. "Adenanthera falcataria" is thus one of the correct names for this plant. There are other correct names, based on different taxonomic treatments. The four names "Adenanthera falcataria", "Albizia falcataria", "Paraserianthes falcataria" and "Falcataria moluccana" are each correct, given that the plant is placed in these four genera.
