“METHODS: A multiethnic sample of 656 elementary school girls recruited from 13 schools in Hayward, CA, and Tucson, AZ, was evaluated annually

over a 4-year period. The McKnight Risk Factor Survey IV was administered, which consists of 103 questions that assess self-esteem, appearance appraisal, effect of body changes, depressed mood, teasing, school performance, and other factors. In addition, participants’ heights and weights were measured.\n\nRESULTS: GW4869 mw The most important predictor of self-esteem in each grade was appearance appraisal, and, in all grades but the eighth, weight-related teasing by either boys or girls was also a predictor of self-esteem. Teasing about weight was more important than body weight itself in predicting self-esteem. Self-esteem

was lower in girls who were teased about their weight, even if they believed that it had no effect on how they felt about themselves. School performance predicted self-esteem in grades 6 and 8. In longitudinal analyses, the participant’s current perception of her appearance was more important than her previous level of self-esteem in predicting current self-esteem.\n\nCONCLUSIONS: HM781-36B The results of this study support the need to allocate funding to address the issue of teasing as 1 of the stressors in the school environment, and to explore further the important relationship CCI-779 between school performance and self-esteem.”
“Aposematism

involves predators learning conspicuous signals of defended prey. However, prey species utilize a wide range of chemical (or physical) defenses, which are not likely to be equally aversive to all predators. Aposematism may therefore only be effective against a physiologically sensitive subset of potential predators, and this can only be identified through behavioral testing. We studied the emerging model organism Tectocoris diophthalmus (Heteroptera: Scutelleridae), an aposematically colored but weakly defended shieldback stinkbug, to test the efficacy of its defenses against a suite of predator types. We predicted the bugs’ defenses would be ineffectual against both experienced and naive birds but aversive to predaceous insects. Surprisingly, the opposite pattern was found. Both habituated wild passerines and naive chickens avoided the bugs, the chickens after only one or two encounters. To avian predators, T.diophthalmus is aposematic. However, praying mantids showed no repellency, aversion, or toxicity associated with adult or juvenile bugs after multiple trials. Comparison with prior studies on mantids using bugs with chemically similar but more concentrated defenses underscores the importance of dose in addition to chemical identity in the efficacy of chemical defenses.
