This study is unique because it investigated the retirement transition period and how working after retirement contributes to life quality the relationship between retirement and the subsequent psychological well-being for couples. The orchestra s board president, Robert Attiyeh 56, a Cornell alumnus, commissioned the work. Back to Top Neurobiology and Behavior Thomas Eisner and colleagues discovered the first example of a sexually transmitted chemical defense to benefit a female animal, the rattlebox moth. The chemical is a potent, plant-derived chemical that protects her for life against predatory spiders. It also protects her eggs.
Spiders quickly discover that the moths are inedible.
The distinctively ornate moth, with a pattern of flamingo pink, black, and white, is native to Florida and is one of the few moths that fly during daylight. Until this study, only U. ornatrix eggs were known to benefit from a male s nuptial gift. Pyrrolizidine alkaloids from plants are extruded as a froth when the rattlebox moth is disturbed. Without the lightning-sparked fires of every 10 to 12 years, pine trees isolate the squirrels causing habitat fragmentation and starvation. Natural forest fires help to maintain plant life diversity, help keep non-native plants from taking over, and prevent dense stands of pine tees that prevent the squirrels migration in search of food.
