| Summary: | (MSA), was devised to calculate surface densities of (post oak forest), and pond edge. Observations at the 1996. When S. invicia scouts were active (> 3 ants A method, introduced here as the Multiple Stick Array absence on the surface) of S. invicia are surface activity at pond edges continued at high levels activity: cattle pasture, fallow field, forested edge approached 31.4'C and resumed activity in the afternoon as temperatures fell towards 33.9'C, showing a between these factors. cattle pasture was 0.509, in fallow field 0.273, in components influencing scouting behavior (presence or continued at low levels throughout the day. Surface executed from the fall of 1995 through the fall of forest 0.482, and at pond edge 11.293. Surface activity Four habitat types that are common throughout the landscape matrix of Texas and other regions of the morning when the mean (shaded) surface temperature noted per observation period per MSA), the average number of ants intercepting the observation area in of ants followed a bi-modal pattern in open pastures, of time (5 minutes) in each of these habitats were or late afternoon/evening. Ants ceased activity in the radiation impacting the surface, and the interactions Solenopsis iniicta scouts over time and space. Four southern U.S. were examined for surface scouting speculate that the three most important abiotic statistically significant difference between the sub array level (surface area ca. 0.5m2) over a period sub arrays of six sticks each were deposited on the substrate and all ants that cross the sticks are noted. Surface activity in shaded forest areas usually temperature means (t = - 2.89- df = 20; P = 0.009). temperature, surface humidity, and amount of solar the majority of activity occurred during either morning throughout the day. Based on these observations, I |
