Relationship between Reflectance and Soil Water Content of the RIFA Nest
In this study, wetness of soil was also found to affect the RIFA nest soil reflectance (Fig.
The results show that the effect of soil water content on the reflectance of the RIFA nest soil was insignificant (p > 0.
With the RIFA nest soil reflectance and moisture at the 900 nm wavelength as an example, the following linear equation can be obtained:
Mount (1981) speculated that several reptile species were declining as a result of RIFA predation.
Many amphibian and reptile species may be vulnerable either to direct or indirect RIFA impact due to shared food habits with RIFAs and an egg stage vulnerable to RIFA predation.
The literature contains numerous references to RIFA predation on birds.
Mount (1981) attributed the decline of the common nighthawk (Chordeiles minor), common ground-dove (Columbina passerina), and eastern meadowlark (Sturnella magna) to RIFA predation in southern Alabama.
Laboratory studies of RIFA foraging on grass clippings were conducted over a period from Sep 2004 to Dec 2005.
RIFA lab colonies were established from large nearly complete field-collected colonies, transferred to the laboratory, and allowed to become acclimated for several weeks.
Foragers from the lab-reared RIFA colonies were introduced via glass travel tubes (6.
Since there were far more RIFA foragers at 5 h and the experiment was being terminated, each dish was physically removed from the test arena to a holding plastic box where the ants could be more easily counted.
