“…ECM woody plants have been shown to have thinner roots and greater branching intensity than AM woody plants (Comas, Callahan, & Midford, 2014). Mixed AM and ECM woody forest communities could thus have a higher functional diversity and complementarity with regard to root architectural/phenological characteristics (traits) which could lead to higher ecosystem process stability (Diaz & Cabido, 2001 The community structure of European forests has been studied extensively, particularly with regard to the phytosociological nature of the communities (Spribille & Chytrý, 2002). While the contribution of these studies to our understanding of forests is undeniable, we still lack predictive ecological tools to understand the implications of human in-…”

In late‐successional environments, low in available nutrient such as the forest understory, herbaceous plant individuals depend strongly on their mycorrhizal associates for survival. We tested whether in temperate European forests arbuscular mycorrhizal (AM) woody plants might facilitate the establishment of AM herbaceous plants in agreement with the mycorrhizal mediation hypothesis. We used a dataset spanning over 400 vegetation plots in the Weser‐Elbe region (northwest Germany). Mycorrhizal status information was obtained from published resources, and Ellenberg indicator values were used to infer environmental data. We carried out tests for both relative richness and relative abundance of herbaceous plants. We found that the subset of herbaceous individuals that associated with AM profited when there was a high cover of AM woody plants. These relationships were retained when we accounted for environmental filtering effects using path analysis. Our findings build on the existing literature highlighting the prominent role of mycorrhiza as a coexistence mechanism in plant communities. From a nature conservation point of view, it may be possible to promote functional diversity in the forest understory through introducing AM woody trees in stands when absent.

“…The growth and persistence of spruce species are primarily favored by environmental/climatically driven light shading conditions and/or low light levels and by wet‐cool climates (Zhou and Yang ). In addition, temperature tends to be one of the decisive factors that influence the distribution, growth, and reproduction of spruces, and moisture conditions tend to be the second most influential factor (Gordon and Sirois ; Spribille and Chytry ; Meunier et al. ).…”

“…Spruces (Picea Dietr., Pinaceae), distributed in the Northern Hemisphere across Eurasia and North America, are dominant species in boreal forests and in cold-temperate coniferous mountain forests (Spribille and Chytry 2002). The genus Picea includes approximately 35 species (Farj on 1990), nearly half of which (16 taxa, including seven endemic species) are naturally distributed in China (Fu et al 1999), extending over a wide geographical range (23-53°N, 75-134°E) and exhibiting a steep climatic gradient (Zhou and Yang 1980;Li et al 2012).…”

This study explored the relative roles of climate and phylogenetic background in driving morphometric trait variation in 10 spruce taxa in China. The study further addressed the hypothesis that these variations are consistent with species turnover on climatic gradients. Nine morphometric traits of leaves, seed cones, and seeds for the 10 studied spruce taxa were measured at 504 sites. These data were analyzed in combination with species DNA sequences from NCBI GenBank. We detected the effects of phylogeny and climate through trait‐variation‐based K statistics and phylogenetic eigenvector regression (PVR) analyses. Multivariate analyses were performed to detect trait variation along climatic gradients with species replacement. The estimated K‐values for the nine studied morphometric traits ranged from 0.19 to 0.68, and the studied environmental variables explained 39–83% of the total trait variation. Trait variation tended to be determined largely by a temperature gradient varying from wet‐cool climates to dry‐warm summers and, additionally, by a moisture gradient. As the climate became wetter and cooler, spruce species tended to be replaced by other spruces with smaller needle leaves and seeds but larger cones and seed scales. A regression analysis showed that spruce species tended to be successively replaced by other species, along the gradient, although the trends observed within species were not necessarily consistent with the overall trend. The climatically driven replacement of the spruces in question could be well indicated by the between‐species variation in morphometric traits that carry lower phylogenetic signal. Between‐species variation in these traits is driven primarily by climatic factors. These species demonstrate a narrower ecological amplitude in temperature but wider ranges on the moisture gradient.

“…A variety of methods have been used to assess and characterize the area of boreal forest, including field surveys, aerial photographs, and satellite remotely sensed data (e.g., Spribille and Chytry 2002, Gamon et al 2004, Mather 2005. Different methods result in the measurement of different variables, at differing scales, and the resulting areal estimates are thus not directly comparable.…”

Boreal forest nations are often thought to have similar environmental, social, and economic contexts. In this communication we show that boreal forest nations are a disparate grouping, with some similarities and many differences. Highlighting these differing national contexts provides insights into how a given nation utilizes the boreal forests over which it holds stewardship responsibilities. Current national contexts are related to each nation's physiography, climate, history, legacy of past forest management, the timing of transition from natural to plantation forests, population density and distribution, and access to resources and markets. Boreal forests are dominated by pioneer species that are resilient to disturbance and have a demonstrated ability to adapt to past climate changes. National responses to natural disturbances are linked to forest area, ownership, and management intensity. Boreal forests in large nations (e.g., Canada, Russian Federation) are typically publicly owned, and disturbances such as fire are allowed to progress naturally over remote areas. In smaller nations, where there is often a greater proportion of private ownership and a focus on production forestry, natural disturbances are more aggressively controlled (e.g., Sweden, Finland). Large nations with low boreal human population densities have a greater proportion of natural boreal forest, with relatively higher levels of biodiversity when compared to the fully managed forests of some smaller boreal nations. In smaller nations, the combination of limited forest area and private ownership has facilitated the dominance of intensive sustainable forestry management practices (e.g., Finland). Conversely, in nations with more spatially extensive forest assets that are publicly owned and managed to meet multiple objectives, extensive sustainable forest management practices dominate (e.g., Canada, Russian Federation).Key words: boreal forest, global, national circumstances, environmental, social, economic, forestry practices, Canada RÉSUMÉ Les pays forestiers nordiques sont souvent perçus comme ayant un contexte environnemental, social et économique semblable. Dans cet article, nous démontrons que les pays forestiers constituent un groupe disparate ayant quelques similitudes et plusieurs différences. La mise en évidence de ces contextes nationaux différents permet une vision intrinsèque de l'utilisation faite par un pays donné des forêts boréales pour lesquelles il détient des responsabilités d'intendance. Les contextes nationaux actuels sont décrits selon la géographie physique, le climat, l'histoire, l'héritage de l'aménagement forestier antérieur, l'époque de la transition des forêts naturelles vers les plantations, la densité et la distribution de la population, ainsi que l'accès à la ressource et aux marchés de chaque pays. Les forêts boréales sont dominées par des espèces pionnières qui sont résilientes suite à une perturbation et ont une capacité démontrée de s'être adaptées aux changements climatiques du passé.
