Fig. 5From: Individual vulnerability factors of Silver fir (Abies alba Mill.) to parasitism by two contrasting biotic agents: mistletoe (Viscum album L. ssp. abietis) and bark beetles (Coleoptera: Curculionidae: Scolytinae) during a decline processMean BAI chronology of a population of silver firs (gray; N = 227), sub-samples with mistletoe (dotted line; N = 14), and sub-samples without mistletoe (black; N = 6) on a contour line transect on Mont-Ventoux, France. The values of means (mm2/year) ± standard errors were as follows: population = 904 ± 21.8, sub-samples with mistletoe = 989 ± 30.5, and sub-samples without mistletoe = 588 ± 15.2Back to article page
