Argentina Ants

John Matthews March 6, 2009 Ecology INVASIVE SPECIES: Genetic disagreement in behavior in genus Argentina pismires in indigene and introduced environment. Studies of invasive species in both their native environment and introduced environments argon antiquated according to Tusutsui, N, Suarez, A., Holway, D and Case, T. In their paper trim down contract fitted variation and the advantage of an invasive species (Tsutsui et al., 2000). Their studies of the Argentina ant admit the difference in behavior and population communicables and how that major power correspond with variation in small town structure among the native and introduced populations. An early(a) concept they explored was that the reasons for ill will in the midst of ants and if that expertness explain the Argentine’s ant’s success as an invasive species. They hoard actor ants from nests in southeast America and the United States. In ensnare to be able to examine the relationship bet ween species concerning encroachment and genetic similarity, they collected workers from different supercolonies. They defined a supercolony as a host of nests where no aggression between the Argentina ant and other ant species existed.

Behavioral aggression was tried by selecting unity workers from two different nests and putting them to ramher for five to cristal minutes and scoring the aggression interactions and arrangement the highest level of aggression for each trial they did five to cardinal trials using ants from stochastic nests to calculate the average aggression among the ants. They did not find oftentim es variance of results from each of the tria! ls. For molecular abbreviation ten to xv individuals from each nest were genotyped to determine the genetic similarity between the nests. They discovered that overall the number of alleles in the introduced range is half that found in the native range. They withal discovered that aggression differed between native and introduced ranges. Aggression among the species was commonly absent in introduced populations in contrast to a...If you want to get a full phase of the moon essay, order it on our website: OrderCustomPaper.com
