(Moench) Voss, by comparing budburst on unexploited shoots with that on adjacent shoots bearing a stem galler or on adjacent shoots or branches that had been subjected to one of two levels of herbivory by a defoliator or by a defoliator/stem feeder in the previous year.
The poorer vigor of progenies from nearest neighbor crosses, relative to longer distances crosses, has been interpreted as inbreeding depression and an indirect measure of relatedness in Picea glauca
(Coles and Fowler 1976; Park and Fowler 1984), Larix laricina (Park and Fowler 1982), and a number of small perennial species (e.g., Waser and Price 1989; Hauser and Loeschcke 1994; Waser and Price 1994), but has not been detected in some populations of short-lived plants (McCall et al.
