Nitrogen additions (NH4NO3) at rates of three- and ten-fold ambient atmospheric deposition (8.5 kg ha(-1) year(-1)) were realised in an acid- and base-poor northern hardwood forest of Québec, Canada. Soil solution chemistry, foliar chemistry, crown dieback and basal area growth of sugar maple (Acer saccharum Marsh.) were measured. Except for a transitory increase of NO3 and NH4 concentrations, there was no persistent increase in their level in soil solution 3 years after N treatments, with the exception of one plot out of three, that received the highest N addition, beginning to show persistent and high NO3 concentrations after 2 years of N additions. Three years of N additions have significantly increased the N DRIS index of sugar maple but not N foliar concentration. Potassium, Ca and Mn foliar concentrations, as well as P and Ca DRIS indices, decreased in treated plots after 3 years. No treatment effect was observed for basal area growth and dieback rate. One unexpected result was the significant decrease in foliar Ca even in the treated plots that received low N rates, despite the absence of significant NO3-induced leaching of Ca. The mechanism responsible for the decrease in foliar Ca is not known. Our results, however, clearly demonstrate that increased N deposition at sites with low base saturation may affect Ca nutrition even when clear signs of N saturation are not observed.

“…Maple is a nutrient-demanding species (e.g., Drohan et al 2002) and it has been suggested that base cations impoverishment led to a growth decline of canopy trees (e.g., Ryan et al 1994;Duchesne et al 2002;Watmough 2002). Controlled experiments have demonstrated a strong increase in growth of adult maple trees and improved crown conditions following liming (e.g., Long et al 1997;Moore et al 2000). Maple seedlings submitted to experimental acidic depositions showed nutrition deficiencies, symptoms of toxicity, decreased photosynthetic capacities, and reductions in growth and survival (e.g., Kobe et al 2002;Juice et al 2006).…”

Sapling age structure and growth series reveal a shift in recruitment dynamics of sugar maple and American beech over the last 40 years

Northern hardwoods have undergone a marked change in their dynamics, with American beech (Fagus grandifolia Ehrh.) increasing in abundance relative to sugar maple (Acer saccharum Marsh.). This study aims to better understand this sudden shift in recruitment dynamics. We performed an extensive analysis of the age structure, radial growth pattern, and release history on >700 saplings from 34 mature maple-beech stands of southern Quebec. We found (i) that the sapling age structures showed a progressive decrease in the establishment of maple relative to beech starting about 40 years ago, (ii) a change in the species growth hierarchy that started in the 1980s due to increasing radial growth of beech, (iii) that this growth trend is negligible for both maple and beech when we account for size and suppression status, and finally (iv) that the growth trend appears to be independent of present soil conditions. These results contrast with previous studies conducted at the adult stage that reported a growth decline for maple. We conclude that this change in recruitment dynamics is not related to growth, and consequently, further studies investigating this phenomenon should concentrate on establishment and survival.Résumé : La dynamique des forêts de feuillus tempérées a changé de façon marquée avec l'augmentation de l'abondance du hêtre à grandes feuilles (Fagus grandifolia Ehrh.) par rapport à celle de l'érable à sucre (Acer saccharum Marsh.). Cette étude vise à mieux comprendre ce changement soudain de dynamique du recrutement. Nous avons réalisé une analyse de la structure d'âge, du patron de croissance radiale et de l'historique de dégagement de plus de 700 gaules provenant de 34 peuplements matures d'érable et de hêtre du sud du Québec. Nous avons trouvé (i) que la structure d'âge des gaules indiquait une diminution progressive de l'établissement de l'érable par rapport au hêtre, processus qui a commencé il y a environ 40 ans, (ii) un changement de hiérarchie dans la croissance des espèces qui a commencé dans les années 1980 à la suite d'une hausse de croissance radiale du hêtre, (iii) que cette tendance de croissance est négligeable pour l'érable et le hêtre lorsqu'on tient compte de la taille et du statut d'oppression des individus, et enfin (iv) que la tendance de croissance semble indépen-dante des présentes conditions de sol. Ces résultats sont différents de ceux d'études antérieures réalisées au stade adulte et qui rapportaient un déclin de la croissance de l'érable. Nous concluons que ce changement de dynamique du recrutement n'est pas relié à la croissance et, par conséquent, que les futures études portant sur ce phénomène devraient se concentrer sur l'établissement et la survie.[Traduit par la Rédaction]
