American Samoa makes up the eastern end of the Samoan Archipelago. On the islands of Tutuila, Ta'u and Ofu, the National Park of American Samoa (NPSA) protects about 4,000 ha of coastal, mid-slope and ridge-top forest. While the ant fauna of the Samoan Archipelago is considered relatively well documented, much of NPSA has never been surveyed for ants, leaving the fauna and its distribution poorly known. To address this shortfall, we systematically surveyed ants within the Tutuila and Ta'u units of NPSA using standard methods (hand collecting, litter sifting, and baits) at 39 sites within six vegetation types ranging from 8 to 945 m elevation. Forty-four ant species were identified, 19 of which are exotic to the Samoan Archipelago. Two notoriously aggressive species, Anoplolepis gracilipes and Pheidole megacephala were detected at two and seven sites, respectively. Both of these species largely excluded all other ants from bait, although their impact on ant community composition is unclear. A suite of habitat variables measured at each site was assessed to explain park-wide ant distributions. Of eight variables evaluated, only elevation was associated with ant community structure, as the ratio of native to exotic ant species increased significantly with elevation on Tutuila. Our survey documented two species not previously reported from American Samoa. Strumigenys eggersi, detected at 12 sites, appears to be a new immigrant to the Pacific Basin. A species of Pheidole was collected that likely represents an undescribed species. Solenopsis geminata, an aggressive species first reported on Tutuila in 2002, was not detected during our survey.

As a tropical archipelago, the Florida Keys provide an ideal environment to examine the historic and short-term processes that structure and influence biological diversity. Through a new survey of the ants of the Florida Keys, we increase our knowledge of the number of species to 94 representing 34 genera and 8 subfamilies. Through detailed collection information, we provide an in depth picture of the distribution of each species across the Keys. On the basis of these data and information on the native and known distributions of each species, we confirm the historical trend toward continued immigration of nonnative species into the Florida Keys and present these findings in the context of the proportion of native to nonnative species. We find a similar number of species introduced from the Old World and Neotropical mainland and discuss the probable immigration of mainland Florida species during the exposure of the Florida Shelf during the last glacial episode and the subsequent isolation of some populations as sea level rose following the last glaciation. Lastly, we discuss the possible threats to these populations due to rapid climate change and other human influences.

The Florida list (Deyrup, M.,Johnson, C.,Wheeler, G.C., \& Wheeler, J.) published in1989 is replaced to accomodate 49 additional species now know from Florida, and 34 name changes in species already on the 1989 list. Currently, 218 species of ants are reliably reported from Florida. The native species Formica subsericea \& Solenopsis xyloni, and the exotic species Myrmelachista ramulorum \& Tetramorium lanuginosum have not been found in many years and may have been extirpated. Some taxonomic notes are given.

A new survey of the ants of the Florida Keys increases the known fauna from 30 to 83 species. An annotated list provides data on habitats, collection sites, and location of vouchers. Solenopsis corticalis Forel, Leptothorax torrei (Aguayo) and Monomorium ebeninum Forel are new records for the U.S. The fauna includes 27 exotics and 31 species native to the Southeastern Coastal Plain; most of the remaining species are Antillean. There are 2 possibly endemic species. The proportion of known exotics (33\%) in the fauna is the highest for any area in the U.S. There is evidence that populations of certain exotics are increasing with increasing disturbance of remaining native habitats. Species diversity in the Keys is probably limited by 1) limited habitat diversity, 2) lack of easy access to the rich ant fauna of the Neotropics, and 3) unsuitability of the climate and habitats for many species found farther north.
