Question

2) Interpret figures 1 and 2. How does recruitment to baits differ in areas with and without Argentine ants? (10 pts) How are native ants affected by the Argentine ants? (10 pts) Can any species tolerate the presence of Argentine ants? (10 pts) How do you know this? (10 pts) Fig. 1 Fig. 2 probability of recruitment to bait duration of time at bait (min) Cc Cs Cv Fm Lh Ma Pc Sm Ts WA maximum number of ants at bait (areas with only native ants) (areas with only Argentine ants) (areas with both native ants and Argentine ants) Ts Cc Cs Cv Fm Lh Ma Pc Sm species

Answer 1

1.- The areas without argentine ants show a very high recruitment to baits compared to the areas with argentine ants.

2.- The native ants don't decrease the number of individuals visiting the baits when argentine ants are around, and it seems they reduce the time spent at the bait too.

3.- I would dare to say there are three species that somehow withstand the presence of argentine ants: Cc, Ma y Sm.

4.- Because they show high values compared to Lh, in presence of Lh (I'm assuming graphs A and B were measured in Lh presence). But another measure needs to be made. We need to compare such values with and without argentine ants, in order to know if there's any change in each of the other ant species. If the change before and after is insignificant, then such species withstand the argentine ant.
