In forested ecosystems, shrubs must succeed in persisting in low‐light environments, while simultaneously having the ability to rapidly expand and occupy newly created canopy openings, yet little is known about the traits that make this possible. We hypothesize that shrub species that are abundant in the understory exhibit a specific set of functional traits that define their ability to persist during unfavorable periods and to rapidly exploit newly created habitats. We tested this by comparing field‐measured functional traits such as biomass allocation, leaf display, crown morphology, and leaf traits, across individual size classes and two gap‐forest environments of five shrub species. We observed significant differences in traits between species, size classes, and gap‐forest environments. These differences were primarily related to biomass allocation traits, followed by leaf display, crown morphology, and leaf traits. Abundant shrubs like mountain maple (Acer spicatum) and hazelnut (Corylus cornuta) invested significantly more biomass in roots, had a larger total leaf area, and displayed leaves in a more efficient manner to intercept light. The high investment in root biomass can be interpreted as shrubs exploiting the persistence and colonization strategy through resprouting. Permanent sub‐canopy status likely explains the importance of efficient leaf display, wherein abundant shrubs had a large leaf area with minimal support structures. [ABSTRACT FROM AUTHOR]

- Abstract
Global changes affect the growing conditions of terrestrial ecosystems, causing a mismatch between plant phenology and local climates in Northern regions. Due to their long lifespan and irregular regeneration periods, trees cannot respond quickly enough to climate variability through long-term genetic adaptation. In this study, we explored the phenological plasticity and genetic variation among populations of bud burst in sugar maple (Acer saccharum Marsh.) seedlings from 30 Canadian provenances with contrasting climates planted in two common gardens near and at the northern limit of the species’ range. We tested the hypothesis that phenotypic plasticity and genetic variation among populations affect bud phenology. We expect that phenotypic plasticity is more important in regulating bud phenology due to the high variability in short-term weather events characterizing this part of North America. Bud development and leafing occurred in April–May, with complete bud burst lasting between 21 and 29 days. On average, bud swelling differed by 12 days between common gardens. Both factors site (common gardens) and provenance significantly affected bud burst, demonstrating phenological plasticity and genetic variation of sugar maple, respectively. A significant interaction between site and provenance was also found. Overall, the site (11.8–90.3%) contributed more than provenance (0–3.1%) to the variance in timings of bud burst, indicating a dominant role of plasticity in regulating spring phenology. Our study demonstrated the concurring effects of genetic variation and phenological plasticity of sugar maple and revealed the dominant role of the latter factor. The high plasticity observed in sugar maple has a crucial role in the phenological adaptation of maple and the survival of its local populations in a context of changing climate.

Small-seeded tree species such as yellow birch (YB, Betula alleghaniensis Britt.) require deadwood or mineral soil for their establishment. Although much research has been done comparing YB germination on leaf litter vs. exposed mineral soil, less is known about deadwood as a seedbed and how different seedbeds affect YB early growth along light availability and size gradients. We examine how three common seedbeds (deadwood, moss cover on deadwood, and mineral soil) affected establishment and growth, biomass partitioning, and morphological traits of YB juveniles growing in the understory of temperate mixed deciduous and coniferous forests in southern Quebec. A total of 274 YB were sampled in four sugar maple (Acer saccharum Marsh.) dominated northern hardwood stands where selective cuts had been applied 6 and 15 years prior to sampling. Over 75% of the YB found on deadwood were on material of birch and conifer origin, although these species made less than 40% of the basal area. YB juveniles growing on deadwood showed traits that improve survival in shade such as reduced height growth for tall plants, higher efficiency in resource capture, and multilayered crowns. Our results demonstrate the importance of deadwood of birch and conifer origin in maintaining an abundant, natural, spatially well-distributed, and multistoried regeneration of YB. Key words: Betula alleghaniensis, seedbed, deadwood, biomass partitioning, selective cut. Les especes d'arbre qui produisent de petites graines, comme le bouleau jaune (BJ, Betula alleghaniensis Britt.), necessitent du bois mort ou du sol mineral pour s'etablir. Bien que plusieurs etudes aient compare la germination du BJ sur la litiere de feuilles et le sol mineral, on connait moins le bois mort comme lit de germination et comment differents lits de germination influencent la croissance juvenile du BJ en fonction de gradients de disponibilite de la lumiere et de taille. Nous etudions comment trois lits de germination communs (bois mort, bois mort recouvert de mousses et sol mineral) influencent l'etablissement, la croissance, la repartition de la biomasse et les traits morphologiques de jeunes BJ se developpant sous un couvert de forets temperees mixtes de feuillus et de coniferes du sud du Quebec. Au total, 274 BJ ont ete echantillonnes dans quatre peuplements de feuillus nordiques domines par l'erable a sucre (Acer saccharum Marsh.) ou des coupes de jardinage avaient ete effectuees 6 et 15 ans avant l'echantillonnage. Plus de 75% des BJ observes sur du bois mort etaient etablis sur un substrat de bouleau ou de coniferes, bien que ces especes representaient moins de 40% de la surface terriere. Les jeunes BJ croissant sur du bois mort avaient des traits qui ameliorent leur survie en conditions ombragees, tels qu'une croissance en hauteur reduite chez les grands individus, une acquisition des ressources plus efficace et une cime multicouche. Nos resultats demontrent l'importance du bois mort provenant de bouleaux et de coniferes pour maintenir une abondante regeneration naturelle de BJ spatialement et verticalement bien distribuee.

Sugar maple (SM, Acer saccharum Marsh.) dominated forests of North America are increasingly affected by many human-induced modifications in environmental conditions. As a remedy, adapted silvicultural treatments are needed. Even though it is generally accepted that SM health is related to soil fertility and even though there is extensive literature on SM-American beech (AB, Fagus grandifolia Ehrh.) regeneration stand dynamics related to light availability, the interaction between these two factors has rarely been studied. Our main objective was thus to verify the possible role of a light-soil interaction on SM-AB stand dynamics. We used a factorial design with three factors (harvest intensity, liming, and AB sapling elimination) to test this interaction. Our results showed that the radial growth of SM and AB tree and sapling growth was positively affected by canopy opening but not by liming. Liming did not favour AB seedlings, whereas it favoured SM seedlings in specific canopy opening situations, confirming, albeit partially, the light-soil interaction hypothesis. Overall, liming had very limited effects on SM-AB stand dynamics compared with canopy opening and AB sapling elimination treatments. We do not advocate the extensive use of liming, as other silvicultural strategies tested provided more promising results to favour SM over AB. Key words: maple-beech dynamics, liming, fertilization, hardwood silviculture, hardwood regeneration. Les forets nord-americaines dominees par l'erable a sucre (ERS, Acer saccharum Marsh.) sont de plus en plus influencees par des modifications des conditions environnementales d'origine anthropique. Pour remedier a cette situation, des traitements sylvicoles adaptes sont necessaires. Meme s'il est generalement accepte que la sante de l'ERS est liee a la fertilite du sol et qu'il y a une litterature abondante sur la dynamique de la regeneration des peuplements composes d'ERS et de hetre a grandes feuilles (HEG, Fagus grandifolia Ehrh.) en fonction de la disponibilite de lumiere, l'interaction entre ces deux facteurs a rarement ete etudiee. Notre objectif principal etait donc de verifier le role potentiel d'une interaction entre la lumiere et le sol sur la dynamique des peuplements composes d'ERS et de HEG. Nous avons utilise un dispositif factoriel a trois facteurs (intensite de recolte, chaulage et elimination des gaules de hetre) pour tester cette interaction. Nos resultats montrent que la croissance radiale des arbres et des gaules d'ERS et de HEG etait positivement influencee par l'ouverture du couvert, mais pas par le chaulage. Le chaulage n'a pas favorise les semis de HEG, mais il a favorise ceux d'ERS dans des situations specifiques d'ouverture du couvert, ce qui confirme, bien que partiellement, l'hypothese de l'interaction entre la lumiere et le sol. Globalement, le chaulage a eu des effets tres limites sur la dynamique des peuplements composes d'ERS et de HEG comparativement aux traitements d'ouverture du couvert et d'elimination des gaules de HEG. Nous ne preconisons pas l'utilisation generalisee du chaulage puisque les autres strategies sylvicoles testees ont produit des resultats plus prometteurs pour favoriser l'ERS aux depens du HEG.

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. Key words: Fagus grandifolia, Acer saccharum, soil nutrient availability, light availability, saplings, clearcut, partial cut. Des etudes font etat de resultats divergents concernant l'effet de la fertilite du sol et de l'ouverture du couvert forestier sur la densite et la croissance de l'erable a sucre (AS; Acer saccharum Marsh.) et du hetre d'Amerique (FG; Fagus grandifolia Ehrh.) sous couvert. L'objectif principal de cette etude etait d'evaluer l'effet d'un gradient d'ouverture du couvert forestier et de la fertilite du sol sur la densite et la croissance des gaules d'AS et de FG dans le sud-ouest du Quebec, au Canada. Nous avons echantillonne 56 peuplements contenant des AS et des FG ayant ete soumis a differents types d'historique de perturbation (THP) (FN, forets non amenagees; CP, coupes partielles; CT, coupes totales) sur differents types de sol. La variation des densites absolue et relative des gaules d'AS et de FG entre les 56 peuplements etait importante, mais nous n'avons trouve aucun effet significatif du THP, de la disponibilite des nutriments du sol ou de leur interaction. La croissance radiale des deux especes a reagi positivement a l'ouverture du couvert, mais la croissance de FG etait legerement superieure a celle d'AS dans les CP comparativement aux autres traitements du couvert forestier. Contrairement a notre hypothese, la croissance d'AS n'etait pas significativement plus grande que celle de FG a la suite d'une CT. Ces resultats n'appuient pas l'idee qu'on puisse favoriser l'abondance et la croissance d'AS en augmentant l'intensite des ouvertures par la coupe, a tout le moins sur les sols generalement acides et pauvres en bases qui ont ete etudies.

Context In temperate hardwood forests, increased intensity of soil and canopy disturbances tends to increase species richness due to the establishment of numerous early-successional plant species. However, while competitive pioneer species from early stages of succession can become recalcitrant and alter patterns of natural regeneration, very few studies have examined longer-term effects of these treatments on plant biodiversity. Aims In this study, we investigated mid-term (ca. 20 years) effects of different regeneration treatments with varying soil and canopy disturbance intensities. We compared understory plant communities in temperate hardwood forests from all the South of Quebec (Canada). Methods Using circular experimental plots of 1962.5 m2 (radius = 25 m), we measured taxonomic and functional diversity indices and soil properties using four levels of disturbance intensity in six temperate hardwood forests of Quebec distributed along a longitudinal gradient. Reference forests, i.e. control forests with no silvicultural treatment known for ≥ 80 years, were compared to 20-year-old single-tree selection cuts, group-selection cuts and group-selection cuts with soil scarification. Results Species richness in both group-selection treatments was higher than that in reference forests. Plant equitability and beta diversity among sites in both group-selection treatments were lower than in single-tree selection cuts and control forests. More intense treatments contributed to the mid-term persistence of recalcitrant competitor species (e.g. Rubus idaeus L., Prunus pensylvanica L.f.) whereas soil scarification appears to have negative sustained effects on species known to be sensitive to regeneration treatments (e.g. Monotropa uniflora L., Dryopteris spinulosa Kuhn). Conclusions In temperate hardwood forests of Southern Quebec, silvicultural treatments of higher intensities resulted in detrimental effects on soil properties, especially in the surface horizon, 20 years after disturbance. This legacy, in turn, affected the composition and diversity of understory plant communities. The more intense silvicultural treatments contributed to the persistence of pioneer species better adapted to a wider range of environmental conditions and resulted in a decrease in understory plant community heterogeneity among sites. Conversely, single-tree selection cutting appeared to be the most appropriate silvicultural treatment for maintaining soil functions and heterogeneity of understory plant communities after 20 years; composition and structure being similar to long-undisturbed forests.

- Abstract
Extreme climatic events that are expected under global warming expose forest ecosystems to drought stress, which may affect the growth and productivity. We assessed intra-annual growth responses of trees to soil water content in species belonging to different functional groups of tree-ring porosity. We pose the hypothesis that species with contrasting carbon allocation strategies, which emerge from different relationships between wood traits and canopy architecture, display divergent growth responses to drought. We selected two diffuse-porous species (Acer saccharum and Betula alleghaniensis) and two ring-porous species (Quercus rubra and Fraxinus americana) from the mixed forest of Quebec (Canada). We measured anatomical wood traits and canopy architecture in eight individuals per species and assessed tree growth sensitivity to water balance during 2008–2017 using the standardized precipitation evapotranspiration index (SPEI). Stem elongation in diffuse-porous species mainly depended upon the total number of ramifications and hydraulic diameter of the tree-ring vessels. In ring-porous species, stem elongation mainly depended upon the productivity of the current year, i.e., number of vessels and basal area increment. Diffuse-porous and ring-porous species had similar responses to soil water balance. The effect of soil water balance on tree growth changed during the growing season. In April, decreasing soil temperature linked to wet conditions could explain the negative relationship between SPEI and tree growth. In late spring, greater water availability affected carbon partitioning, by promoting the formation of larger xylem vessels in both functional groups. Results suggest that timings and duration of drought events affect meristem growth and carbon allocation in both functional groups. Drought induces the formation of fewer xylem vessels in ring-porous species, and smaller xylem vessels in diffuse-porous species, the latter being also prone to a decline in stem e

- Abstract
Plant traits-the morphological, anatomical, physiological, biochemical and phenological characteristics of plants-determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research spanning from evolutionary biology, community and functional ecology, to biodiversity conservation, ecosystem and landscape management, restoration, biogeography and earth system modelling. Since its foundation in 2007, the TRY database of plant traits has grown continuously. It now provides unprecedented data coverage under an open access data policy and is the main plant trait database used by the research community worldwide. Increasingly, the TRY database also supports new frontiers of trait-based plant research, including the identification of data gaps and the subsequent mobilization or measurement of new data. To support this development, in this article we evaluate the extent of the trait data compiled in TRY and analyse emerging patterns of data coverage and representativeness. Best species coverage is achieved for categorical traits-almost complete coverage for 'plant growth form'. However, most traits relevant for ecology and vegetation modelling are characterized by continuous intraspecific variation and trait-environmental relationships. These traits have to be measured on individual plants in their respective environment. Despite unprecedented data coverage, we observe a humbling lack of completeness and representativeness of these continuous traits in many aspects. We, therefore, conclude that reducing data gaps and biases in the TRY database remains a key challenge and requires a coordinated approach to data mobilization and trait measurements. This can only be achieved in collaboration with other initiatives.

Knowledge of plant architecture allows retrospective study of plant development, hence provides powerful tools, through modelling and simulation, to link this development with environmental constraints, and then predict its response to global change. The present study aims to determine some of the main endogenous and exogenous variables driving the architectural development of three North American conifers. We measured architectural traits retrospectively on the trunk, branches and twigs of whole tree crowns for each species: annual shoot length (ASL), needle length, branching patterns and reproduction organs (male and female). We fitted a partial least square (PLS) regression to explain each architectural trait with respect to topological, ontogenic and climatic variables. Results showed a significant weight of these three groups of variables for previous and current year, corresponding, respectively, to organogenesis and elongation. Topological and ontogenic variables had the greatest weight in models. Particularly, all architectural traits were strongly correlated with ASL. We highlighted a negative architectural response of two species to higher than average temperatures, whereas the third one took advantage of these higher temperatures to some degree. Tree architectural development weekly but significantly improved with higher precipitation. Our study underlines the strong weight of topology and ontogeny in tree growth patterns at twig and branch scales. The correlation between ASL and other tree architectural traits should be integrated into architectural development models. Climate variables are secondary in importance at the twig scale. However, interannual climate variations influence all axis categories and branching orders and therefore significantly impact crown development as a whole. This latter impact may increase with climate change, especially as climate affects architectural traits over at least 2 years, through organogenesis and elongation., This study proposes an original insight into tree architectural development, by combining in a simultaneous analysis three sets of explanatory variables: ontogenic, topological and climatic factors. It targets three common North American conifers (Picea mariana; Pinus banksiana; Pinus strobus), the detailed architecture of which is poorly known. Thus it brings new knowledge about these species and their response to environmental constraints. Our results may help improve the assessment of the future of these species in the context of climate change, particularly through the knowledge of interactions between exogenous (climate and site conditions) and endogenous factors (ontogeny, topology).

[Departement_IRSTEA]Territoires [TR1_IRSTEA]SEDYVIN [ADD1_IRSTEA]Dynamique et fonctionnement des écosystèmes; International audience; Des forêts semi-arides aux forêts boréales, en passant par les biomes méditerranéens, tempérés, et montagnards, 19 équipes ont étudié la plasticité du développement architectural de 18 espèces d'arbres soumis à des variations et stress climatiques dans 8 pays sur 3 continents. L'analyse porte sur la croissance des branches, leur ramification, le nombre et la taille des feuilles, la reproduction qui interfère avec ce développement et la phénologie qui en est l'un des moteurs. Le tout dans le milieu naturel, suivant de larges gradients d'altitude et de latitude, et dans des expérimentations contrôlant le climat (température, exclusion de pluie, irrigation). De façon très homogène, tous les arbres étudiés quel que soit le milieu réagissent aux stress en réduisant leur taux de ramification et le nombre de feuilles, en réduisant la taille des feuilles si la contrainte est hydrique et en modifiant leur stratégie reproductive. Nous montrons que l'adaptation de la surface foliaire à la ressource en eau est largement pilotée par la branchaison. L'inertie architecturale restreint l'adaptation foliaire et tamponne la production de biomasse longtemps après un stress fort ou répété. Le changement climatique modifie la phénologie de ces arbres, ajoutant des contraintes à leur développement. La modélisation du développement architectural des arbres dans ses relations au climat est une avancée significative pour comprendre leur capacité d'adaptation au changement climatique et les risques qui en découlent pour la production forestière.

Terminalia Arjuna is an ecologically important agroforestry tree species across Central Asia where imbalance between water inputs and plant uptake is resulting in secondary salinization. Therefore, this study was conducted to evidence its survival capability under control, medium and high salt stress condition (2, 8, 16 dS m
−1, respectively). Two independent experiments were conducted and various parameters such as (i) germination percentage (ii) growth and biomass production and, (iii) leaf gas exchange parameters were measured. The results showed that irrespective of salt stress treatment, germination percentage decreased significantly with increase in salt stress. However, growth parameters and biomass production in leaves, stem and roots were not impacted under medium salt stress but decreased significantly under high salt stress. Stomatal conductance decreased significantly under both salt stress treatments whereas CO2 assimilation rate and water use efficiency was not impacted by medium salt stress. Finally, an increase in biomass production was positively correlated to both increase in CO2 assimilation rate and stomatal conductance. The results showed that although germination in Terminalia arjuna was highly sensitive to salt stress, young plants can tolerate medium salt stress due to their ability to sustain CO2 assimilation rate and increased water use efficiency.
