Adaptive modification of host selection by a hymenopteran parasitoid
The frequency-independent component of selection of different foods (or hosts) by animals may be partly an adaptive response to differences in quality of the foods. The relationship between the selective coefficients for three hosts presented to Nasonia in their three pairwise combinations, as revea...

Zusammenfassung: | The frequency-independent component of selection of different foods (or hosts) by animals may be partly an adaptive response to differences in quality of the foods. The relationship between the selective coefficients for three hosts presented to Nasonia in their three pairwise combinations, as revealed by a new statistical technique, is such as to confirm this view. /// Независимый от частоты компонент избирательности в отношении разных видов пищи (или хозяев) животными может быть частично адаптивной реакцией на раз-личия качества пищи. Представлено соотношение между коеффициентами селек-тивности для трех видов хозяев Nasonia в трех парных комбинациях, опреде-ленных по новому статистическому методу, который подтверждает эту точку зрения. |
