In one study, spiders showed hierarchical preference for single male traits as magnitude increased, but when traits were co-varied, preference patterns differed based on pairing of males. This suggests that females use comparative evaluation, assessing males relatively rather than using fixed scores. In a second study, context effects were tested by adding an alternative to a choice set such that one of the original choices asymmetrically dominated the new option. Preference for particular individuals subsequently varied based on the traits of all males present, suggesting that female preference differs with context, depending on male number and relative quality. Both studies indicate that choice context and comparative evaluation are present in this species. These studies are likely the first to test for such effects in mate choice using theories from economics and animal foraging. 2008-09-22 English text University of Cincinnati / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=ucin1217964666 http://rave.ohiolink.edu/etdc/view?acc_num=ucin1217964666 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
