Rodney Masters What they say Sir Mark Prescott, trainer of Aestival "He had a good early campaign this season with three wins, then ran adequately but was put in his place at Leicester last time.
1970), the presence of larval prey acts as a cue, or token stimulus, to promote aestival reproduction, whereas absence of prey triggers aestival diapause (Tauber and Tauber, 1973b).
For each population, our goal was to quantify the variation in diapause-related traits among individuals from several families under two treatments of photoperiod and two treatments of prey that induce the full expression of variation in aestival diapause observed in previous studies (e.
Individuals undergoing aestival diapause were recognized by the following criteria: lack of reproduction and the assumption of a plump, waxy appearance, which indicates the lack of ovarian development and development of fat tissue.
Heterogeneity among familes in the proportional occurrence of aestival dispause was analyzed with three-way tables using log-linear models (unreplicated data) (Sokal and Rohlf, 1981).
Of the seven populations tested for responses to photoperiod, only the multivoltine population from eastern North America (IC) had no aestival diapause within any family under either constant long daylength or with an increase in daylength (Table 2).
Under constant long daylength (in the absence of prey), most western populations showed significant among-family heterogeneity in the incidence of aestival diapause ([two females and [two males]: PL, AT, TP; [two males] only: LS; G test, [Alpha] = 0.
This afternoon Prescott sends Aestival on the long journey to Ayr for the 6f maiden at 3.
