Nonrandom Pattern

This paper confirms the hypothesis that in a sugar maple – hickory forest, the forest floor vegetation growing near the base of Acer saccharum trunks is distributed following a nonrandom pattern. Bryophytes and herbaceous plants grow mostly near the trunk. In the same microhabitat, woody seedlings, dominated by Acer saccharum, seem unable to get established. This pattern is thought to be correlated with soil depth and the presence of stemflow. It is suggested that, in the community studied, the base of Acer saccharum trees constitutes an ecological niche essentially different from the rest of the forest floor.

Herbaceous And Woody Plants

The vegetation of dolomitic outcrops was sampled in a maple forest of southern Quebec. Multivariate analyses have demonstrated the influence of rockiness and size of outcrop on the distribution of herbaceous and woody plants. These results allow the description of five microcommunities. The flora of small cracks and hollows is exclusively herbaceous and of low diversity. Deeper soils support tree seedlings and saplings (mostly Acer saccharum) and also a diversified herbaceous stratum. The chemistry and mictotopography of outcrops produce mesic soils, rich in organic matter and nutrients. Soil depth segregates among plant species according to the size of their roots. Big outcrops have a more favorable microclimate. Dolomitic outcrops found in maple forests are biogeochemically rich microhabitats, which may support a more varied and abundant vegetation than does the surrounding forest floor. Primary succession on these outcrops is briefly discussed.

Tree Species Composition

Beech bark disease (BBD) has demonstrable ecosystem consequences for eastern US forests stemming from American beech (Fagus grandifolia Ehrh.) mortality, often leading to increased dominance by its competitor, sugar maple (Acer saccharum Marsh.). We hypothesized that this BBD-induced shift in tree species composition leads to changes in soil acid–base chemistry, mediated through differences in leaf litter chemistry of the two species. Using a sequence of plots representing the progression of the disease in the Catskill Mountains, NY, USA, we examined the influence of tree species composition shift on soil chemistry. The BBD impact on tree species composition was confounded by variability in substrate (or nonexchangeable soil) calcium (Ca). While substrate Ca explained much of the variation in acid–base chemistry, increasing BBD was associated with increasing forest floor exchangeable Ca, sum of base cations, base saturation, cation-exchange capacity, and decreasing hydrogen. An apparent threshold effect of substrate Ca on sugar maple litter Ca concentration suggests that underlying soil Ca availability may contribute to the spatial extent and timeframe of BBD-induced shifts in species composition. The species compositional shift is a mechanism contributing to a vegetation effect on soil acid–base status and may partially counteract soil acidification in this acid deposition impacted region.

The phenology, root anatomy, and mycorrhizal colonization of vascular plant species occurring in a hardwood forest site were studied. Sugar maple (Acer saccharum), the dominant tree, ash (Fraxinus americana), another important tree, and the most abundant herbaceous plants were examined periodically. Most of the herbaceous species present were highly colonized by vesicular–arbuscular mycorrhizae (VAM), but some consistently had low levels of VAM, or were nonmycorrhizal, and several had orchid mycorrhizae. Most trees were associated with VAM, although several ectomycorrhizal species occurred in low numbers. Herbaceous plants could be divided into four phenological categories of shoot activity, spring, spring–summer, summer, and fall, but many species had periods of root growth that did not parallel their aboveground activity. Almost all species that produced new roots in summer were well colonized by VAM, while those active mainly in late fall or early spring tended to be nonmycorrhizal. Roots of the woodland plants typically had a well-developed exodermis and also tended to be long-lived and coarse. Possible relationships among these root system characteristics, phenological categories, and levels of mycorrhizal colonization of woodland plants are discussed.

Studies have reported divergent results on the effect of soil fertility and canopy opening on understory density and growth of sugar maple (AS; Acer saccharum Marsh.) and American beech (FG; Fagus grandifolia Ehrh.). The main objective of this study was to evaluate the effect of a gradient of canopy opening and soil fertility on the density and growth of AS and FG saplings in southwestern Quebec, Canada. We investigated 56 stands containing both AS and FG that were subjected to different disturbance history types (DHTs) (UF, unmanaged forest; PC, partial cut; and CC, clearcut) on various soil types. AS and FG absolute and relative sapling density varied greatly among the 56 stands; however, no significant effects of DHT, soil nutrient availability, or their interaction were found. Both species responded positively in terms of radial growth to canopy openings, with FG growth being slightly better than AS growth in PC stands compared with other canopy treatments. Contrary to our hypothesis, AS did not show significantly higher growth than FG following clear-cutting. These results do not support the idea that AS abundance and growth could be promoted by increasing the intensity of the canopy opening during harvest, at least on the generally acidic and base-poor soils that were investigated.
