Table 1: Species composition, frequency, and relative abundance of ants. Frequency is the proportion of samples that contained individuals (in pitfall traps) or nests (on litter plots) of the species. Relative abundance is the proportion of individuals (in pitfall traps) or nests (on litter plots) of the total individuals ( ) or nests collected ( ). Species that were present in at least 20% of the plots or pitfall samples at either site are highlighted in bold type. In 2003, sampling was conducted on 3 dates, 1 site per date. In 2004, sampling was conducted on 2 dates, 3 sites per date.
