Effect of climate change on four species of Azteca in Monteverde, Puntarenas, Costa Rica
There has been extensive, research in the Monteverde area that has shown that both the abundance and range of lizards, amphibians, and birds have been affected global warming (Pounds (1999). Although there have been studies showing changes in abundance of arctic and temperate invertebrates, there ha...

There has been extensive, research in the Monteverde area that has shown that both the abundance and range of lizards, amphibians, and birds have been affected global warming (Pounds (1999). Although there have been studies showing changes in abundance of arctic and temperate invertebrates, there have not been any studies that have shown invertebrate response to climate change in Monteverde. The four species of Azteca ants (xanthochroa, constructor, coeruleipennis, and alfari) were collected along roads in Monteverde and nearby Santa Elena and San Luis at elevations ranging from 700-1500m. The altitudinal ranges from this study were compared to ranges obtained by Longino in 1985 to determine if these four species have shifted upward in elevation (Longino 1989). A one way analysis of variance compared the elevations of the four species to one another and found that all four were statistically different in the elevations that they occupy except for A. xanthochroa and A. constructor which are both high elevation species.
