“…Morphological responses of aerial parts to competition from overstory and understory vegetation have been widely investigated for most temperate tree species. Converging evidence from the literature indicates that the shoots of Fagus seedlings display a large morphological and physiological acclimation capacity to light regime at crown-level [33,39], branch-level [11,26] as well as at leaf-level [5,32,37,39]. In particular, shading is expected to result in leaves with larger specific leaf area (SLA) [42].…”

-Biomass increment, biomass allocation and fine-root morphology were compared on four-year old Fagus sylvatica seedlings growing under low (11% relative irradiance), medium (14-19%) or high (46%) irradiance under natural Pinus sylvestris canopies, and under full light in a weeded meadow in the French Massif Central. Significant differences in biomass increment were found among plots in relation to light regime and interspecific competition. Light regime had little effect on shoot-to-root ratio and biomass allocation, but had a clear impact on above-and belowground morphological variables. Beech seedlings displayed a lower specific root length (SRL) and a higher specific leaf area (SLA) under shade, thus indicating morphological adjustment to shade. Similarly, competition from herbaceous vegetation had a negligible effect on seedling growth and biomass allocation, but significant impact on fine-root morphology. Low SLA and high SRL values at high irradiance coincided with high growth increments. biomass allocation / European beech (Fagus sylvatica L.) / fine-root architecture / interspecific competition / irradianceRésumé -Plasticité de la croissance de l'allocation de biomasse et de la morphologie racinaire chez les semis de hêtre provoquée par l'éclairement et la compétition herbacée. L'accroissement de biomasse, les patrons d'allocation de biomasse et la morphologie des racines fines ont été comparés sur des plants de hêtre (Fagus sylvatica L.) de quatre ans installés sous un boisement naturel de pin sylvestre à faible, moyen et fort éclairement (11 %, 14-19 % et 46 % d'irradiance relative), et en pleine lumière dans une prairie désherbée du Massif Central français. Les plants ont montré des différences significatives d'accroissement en biomasse selon l'éclairement relatif et l'intensité de la compétition avec le pin et les herbacées. L'éclairement a peu affecté le ratio biomasse aérienne / biomasse racinaire et l'allocation de biomasse au sein des différents compartiments, mais a eu un impact clair sur la morphologie foliaire et racinaire des plants. Les hêtres subissant un fort ombrage présentaient des racines fines peu ramifiées (faible longueur spécifique racinaire, SRL) et des feuilles peu épaisses (forte surface spécifique foliaire, SLA), ce qui suggère une faible capacité d'accès aux ressources du sol et un ajustement à une faible énergie lumineuse. De même, la végétation herbacée a eu un faible impact sur la croissance des hêtres et l'allocation de biomasse, mais a affecté significativement la morphologie de leur racines fines. Au total, des valeurs de SLA faibles et de SRL fortes à fort éclairement correspondent à de forts taux d'accroissement en biomasse. allocation de biomasse / hêtre (Fagus sylvatica L.) / morphologie des racines fines / compétition interspécifique / éclairement sous forêt

“…Sugar maple is tolerant of shade conditions of the forest environment (Forcier 1975;Bellefleur and Villeneuve 1984;Beaudet and Messier 1998). The species responds readily to local disturbances induced by windthrows and windsnaps (Canham 1985;Payette et al 1990), and also to larger disturbances caused by clearcut (Albert and Barnes 1987;Bannon et al 2015;Pilon et al 2018), ice storm (Beaudet et al 2007) and fire (Pilon and Payette 2015).…”

Botany D r a f t 2 Abstract: The long-standing hypothesis that sugar maple (Acer saccharum) communities are maintained at equilibrium by present climate and small-scale disturbances is questioned as empirical evidence is accumulating about the ability of the species to withstand several stand-scale disturbances. The fire history of a sugar maple site at the northeastern range limit of the species (Gaspé Peninsula, eastern Canada) was documented to test the hypothesis that this forest type is resilient to fire disturbance. The fire history was reconstructed using radiocarbon-dated soil macrocharcoals. Two main fire periods were recorded during the Holocene. The oldest period occurred between 9055 and 8265 cal. years BP, and was characterized by the presence of conifers, including spruce. After 6900 years of fire-free activities, the second period covered the last 1335 years, and was characterized by the presence of sugar maple in the charcoal assemblage. The dominance of sugar maple after more than 1000 years of recurrent fires underlines the species resilience to frequent site disturbances. The soil of the forest stand was heavily disturbed by earthworms. However, the dense seedling and sapling bank of sugar maple suggests that earthworms do not affect negatively the regeneration and survival of the species.

“…For practical reasons (e.g., greenhouse or transplant experiments, or because there were too few root suckers at a site), only beech of seed origin was included in some studies (Loach, 1970;Latham, 1992;Reid and Strain, 1994;Kobe et al, 2002;Caspersen and Saprunoff, 2005). In other studies, the origin of beech individuals was not specified (Amthor et al, 1990;Beaudet and Messier, 1998;Gill et al, 1998;Wilder et al, 1999;Beaudet et al, 2000;Finzi and Canham, 2000;McClure et al, 2000;Messier and Nikinmaa, 2000;Lin et al, 2001;Ricard et al, 2003). Nevertheless, differences between seedlings and root suckers were reported in a few studies that have addressed the question of beech origin.…”
