The virulence of Armillaria ostoyae isolates from coastal (16) and interior (33) British Columbia, elsewhere in North America (eight) and Europe (six) was assessed on 2‐year‐old Douglas‐fir seedlings in pots during a 3‐year trial. Isolates from most geographical locations infected similar proportions of seedlings, had similar average damage scores and killed a similar percentage of diseased seedlings. Isolates from the coastal region had a significantly higher probability than interior isolates that a diseased seedling received a damage score > 3 on a 1–5 scale, and coastal isolates killed a higher proportion of diseased seedlings than interior isolates. The mean damage score for isolates that had been in culture for 20–25 years was about 25% lower than that for recently collected isolates. The results indicate that the higher incidence and longer duration of mortality in the southern interior of British Columbia compared to the coast can not be attributed to greater virulence of interior isolates of A. ostoyae. 相似文献

The interior forest of protected area(PA)recover quickly in terms of greater diversity and structural complexity than peripheral and outsides, which may be due to high plant-frugivore interactions in the interior forest than the disturbed outsides. To describe the structural and functional differences in tree communities from interior to outside forests with in small PA, we quantitatively analyzed the vegetation of Trishna Wildlife Sanctuary, a rich primate habitat of Northeast India. Vegetation was sampled at C10 cm girth at breast height by 10 m 9 500 m sized20 line transects(10 ha) laid in the interior(N = 7),peripheral(N = 7) and outside(N = 6) zones of this sanctuary. All transects were ordinated by Principal Component Analysis based on correlation between diversity and existing disturbance indices. We found significant differences(P \ 0.05) in taxonomic richness and diversity indices between the habitat. Van diagram confirmed greater unique species richness in the interior zone(64) than peripheral(28) and outside(6) zones. Overall density(ha-1) did not differed across the zones, but basal area(m2ha-1) was significantly(P \ 0.01) high in peripheral zone. Vertical distribution of stem density was linearly declined across zones(r2adj[ 0.70; P \ 0.01) with increase in the canopy height. Horizontal distribution of adult stems showed significant inverse quadratic relationship(r2adj[ 0.80; P \ 0.001), which suggests very low density of canopy forming voluminous trees in the interior zone.Immediate protection, restoration and management of interior regions are required to preserve local plant genetic diversity and also to maintain suitable habitat for threatened wildlife. 相似文献
