Relative representation of pheidole (hymenoptera : formicidae)in local ground ant assemblages of the Americas
Using 195 published ground ant wmmunity surveys from the Amencas, the fauna1 representation of Pheidole was greater than any other genus. No significant relationship between the percent faunal representation with latitude was found, although their representation was much richer in the tropics. Tree...

| Summary: | Using 195 published ground ant wmmunity surveys from the Amencas, the fauna1 representation of Pheidole was greater than any other genus. No significant relationship between the percent faunal representation with latitude was found, although their representation was much richer in the tropics. Tree crops had significantly higher percentages of species of Pheidole than did other habitat types. Furthermore, a significant negative relationship was found between the percent representation of Pheidole and al1 formicines. This effect was stronger than the relationship between formicines and latitude. No significant negative relations were found for other subfamilies. This suggests that Pheidole may compete strongly with formicines, or that these groups are placed on opposite ends of an enviromental stress gradient |
