The Effects of the Invading Tawny Crazy Ants Ecology is the branch in biology that deals with the interactions between organisms and their environment. Tawny crazy ants are an example of ecology by the way they impact ecosystems as invasive species due to the absence of natural predators, pathogens and competitors (Kronauer, 2014). These invasive ant species were found in Texas around 2002 commonly known as tawny (Rasberry) ants and now classified as Nylanderia fulva (Ant, 2013). Tawny crazy ants affect ecosystems as an invasive species. The Red Imported Fire Ants, Solenopsis invicta, are being successfully outcompeted and even displaced by the crazy ants (Gotzek et al., 2012). These crazy ants possess a threat to the fire ant community with the possibility of eventually forcing them out. Tawny crazy ants have much larger population densities than fire ants; as well as exhaust local arthropod environments (Kronauer, 2014). The fire ants are unable to compete against such high numbers and are being driven out or annihilated at local sites. Studies show that populations of the ecological dominant, red imported fire ants declined or were eliminated as the populations of N. fulva spread (LeBrun et al., 2013). Due to the high population density of N. fuvlva, it is highly unlikely that the species will remain stationary to feed. The species will most likely keep spreading if the density in local areas keeps increasing. Currently, arthropod abundance at the population edge show to be the lowest (LeBrun et al., 2013). This is most likely due to insects emigrating from habitats densely populated with N. fulva. Tawny crazy ants are not only outcompeting red imported fire ants, but as well in resistance. The red imported fire ants became successful invasive species particularly because of their alkaloid venom which topical insecticide (Ascunce et al., 2011). This venom
