The possibility of Monochamus urussovi Fisch to pass through all stages of development on aspen (Populus tremula L.) and birch (Betula pubescens L.) trees, apart from conifers, was shown. The aspen was registered as a host plant of this beetle for the first time. The ability to develop on aspen and birch is supposed to develop as an adaptation to successions in the course of which the native coniferous forests are replaced with secondary deciduous ones.

Role of the Forest Entomofauna in Successional Processes

Article

May 2005

V. M. Yanovskii

Participation of the entomofauna in the succession of forest biogeocenoses is analyzed. In stable ecosystems, insects serve as a mechanism providing for long-term ecological stability. In unstable ecosystems, their activities are essentially negative and cause ecosystem degradation.

Productivity and community structure of ectomycorrhizal fungal sporocarps under increased atmospheri...

August 2009 · Ecology Letters

Sporocarp production is essential for ectomycorrhizal fungal recombination and dispersal, which influences fungal community dynamics. Increasing atmospheric carbon dioxide (CO2) and ozone (O3) affect host plant carbon gain and allocation, which may in turn influence ectomycorrhizal sporocarp production if the carbon available to the ectomycorrhizal fungus is dependant upon the quantity of carbon ... [Show full abstract] assimilated by the host. We measured sporocarp production of ectomycorrhizal fungi over 4 years at the Aspen FACE (free air CO2 enrichment) site, which corresponded to stand ages seven to 10 years. Total mean sporocarp biomass was greatest under elevated CO2, regardless of O3 concentration, while it was generally lowest under elevated O3 with ambient CO2. Community composition differed significantly among the treatments, with less difference in the final year of the study. Whether this convergence was due to succession or environmental factors is uncertain. CO2 and O3 affect ectomycorrhizal sporocarp productivity and community composition, with likely effects on dispersal, colonization and sporocarp-dependent food webs.

Twenty-year change in aspen dominance in pure aspen and mixed aspen/conifer stands on the Uncompahgr...

July 2005 · Forest Ecology and Management

Reports of decreasing quaking aspen (Populus tremuloides) cover in forests of the western USA have caused concern about the long-term persistence of aspen on landscape scales. We assessed changes in overstory aspen dominance on the Uncompahgre Plateau in western Colorado over a 20 year period. We measured stand density, species composition and regeneration in 53 undisturbed, mature pure aspen, ... [Show full abstract] pure conifer, and mixed aspen/conifer stands originally inventoried between 1979 and 1983. Ages of overstory and understory trees were used to evaluate long-term change in regeneration and overstory development.

Succession forestière après feu dans la sapinière à bouleau jaune du Bas-Saint-Laurent, Québec

December 1997 · The Forestry Chronicle

Forest successions following a forest fire that occurred in 1932 were studied on mesic sites of the boreal mixedwood forest of the Bas-Saint-Laurent region of Quebec, Canada. Physiographic, soil and vegetation data were collected in 28 ecosystems distributed on a topographic gradient. The vegetation composition of the main canopy, 64 years after the fire, varied according to topographic ... [Show full abstract] situation. The proportion of tolerant hardwood species (yellow birch (Betula alleghaniensis Britton), sugar maple (Acer saccharum Marsh.), red maple (Acer rubrum L.)) increased toward upper slopes whereas it was the opposite for coniferous species (white spruce (Picea glauca [Moench] Voss), balsam fir (Abies balsamea [L.] Mill.)), as their proportion increased toward lower slopes. Intolerant hardwood species (white birch (Betula papyrifera Marsh.), trembling aspen (Populus tremuloides Michx.)) were abundant in all ecosystems. The distribution pattern of regeneration density and stocking of tolerant hardwoods and conifers w...

Suitability of Native Broadleaf Species for Reforestation in the Cariboo Area of the Southern Interi...

A study to gather information about the establishment and growth of broadleaf trees, and to compare their performance with that of common conifer species in the eastern half of the former Cariboo Forest Region (now part of the Southern Interior Forest Region), was established in 993. Black cottonwood, aspen, birch, interior spruce, and lodgepole pine were planted on sites in the ICHwk2, SBSwk, ... [Show full abstract] SBSdw, SBSdw2, and IDFdk3 biogeoclimatic variants. Conifers were performing well aft er 0 years, but survival of broadleaves was generally poor and their growth was moderate at best. Broadleaves readily naturally regenerate in the Cariboo following disturbance, however, and generally have better initial growth than coni- fers. Th erefore, these results should not be considered representative of the overall potential of broadleaf trees to contribute to the maintenance of forest health and timber supply in the Cariboo. Th is paper provides 0 years of results from this study and includes conclusions and recommendations regarding the potential use of planted broadleaf seedlings in the Cariboo.
