Environmental factors can lead individuals down different developmental pathways giving rise to distinct phenotypes (phenotypic plasticity). The production of winged or unwinged morphs in aphids is an example of two alternative developmental pathways. Dispersal is paramount in aphids that often have a metapopulation structure, where local subpopulations frequently go extinct, such as the specia...

Flight muscles of the cricket Gryllus firmus are polymorphic, existing as pink or white phenotypes. White muscles are smaller in size, have reduced number and size of muscle fibers, and have reduced in vitro enzyme activities and respiration rates relative to pink muscles of newly molted, fully winged adults. G. firmus is also polymorphic for wing length. All newly molted long-winged adults exh...

RESUMEN: La tradición emblemática declara los vicios con símbolos monstruosos. Los emblemas usan frecuencia motivos teratológicos para expresar las deformaciones producidas por el mal en organismo social. Es un saber antiguo, mítico y práctico, al servicio de gobernantes. Mediante esta plástica pedagogía se enseñan virtudes a través figuras nobles animales mediante representaciones monstruos. E...

Aphids exhibit wing polyphenism (winged or wingless) for adaption to predictable or temporally heterogeneous environmental changes; however, the underlying mechanism is still unclear. This morphological change could be stimulated by high aphid density, which in turn could affect octopaminergic signaling in aphids. Octopamine is a neurotransmitter synthesized in insects that can modify their phy...

Thirty-five years ago I argued that portraying rhetoric as the inexorable result of real situational demands, as opposed to competitive persuasion, creating perceptions of situational demands, would relegate the field to secondary disciplinary status and ethical irrelevance. Since then, this prediction has been largely fulfilled, but a change in perspective can make rhetoric a primary study wit...
