The area of forest plantations is increasing worldwide helping to meet timber demand and protect natural forests. However, with global change, monospecific are increasingly vulnerable abiotic biotic disturbances. As an adaption measure we need move that more diverse in genotypes, species, structure, a design underpinned by science. TreeDivNet, network tree diversity experiments, responds this assessing the advantages disadvantages mixed species plantations. currently consists 18 distributed...
Abstract Enhancing tree diversity may be important to fostering resilience drought‐related climate extremes. So far, little attention has been given whether can increase the survival of trees and reduce its variability in young forest plantations. We conducted an analysis seedling sapling from 34 globally distributed experiments (363,167 trees, 168 species, 3744 plots, 7 biomes) answer two questions: (1) Do drought alter mean plot‐level survival, with higher less variable as increases? (2)...
Tree diversity in forests is an important driver of ecological processes including herbivory. Empirical evidence suggests both negative and positive effects tree on herbivory, which can be, respectively, attributed to associational resistance or susceptibility. experiments allow testing for effects, but regarding pattern predominates mixed. Furthermore, it unknown if herbivory species native vs. exotic origin influenced by changing a similar way, escape natural enemies, resulting lower...
Successful establishment of fast-growing trees could depend on early root development and the access to belowground resources. Boreal podzolic soils present a distinctive vertical zonation wherein nutrient availability presence plant roots decline sharply with depth. Mechanical soil preparation that modifies arrangement layers creates microsites improved physical conditions but potentially lower availability. We compared distribution proximal young hybrid poplars in mechanically prepared (by...
For decades, ecologists have investigated the effects of tree species diversity on productivity at different scales and with approaches ranging from observational to experimental study designs. Using data five European national forest inventories (16,773 plots), six experiments (584 networks comparative plots (169 we tested whether growth responses mixing are consistent therefore transferrable between those research approaches. Our results confirm general positive effect (16% average) but...
Multi-cohort forest management in northern hardwood stands may well be the best way to successfully regenerate tree species of intermediate shade tolerance, such as yellow birch (Betula alleghaniensis Britt.). The creation large enough gaps canopy favors increased light availability within opening, while soil scarification provides suitable germination seedbeds. Evidence these methods’ success nonetheless remains mostly purview experimental studies rather than operational tests. In Quebec,...
Fertilization of hybrid poplar (HP) plantations with papermill by-products is a promising solution to improve soil fertility and nutrient availability, increase plantation productivity, provide added value these materials that would otherwise be incinerated or sent the landfill. We assessed growth foliar nutrition HP clone (Populus ×canadensis × Populus maximowiczii) at six sites aged 3–5 years in southern Quebec, Canada. Sites received fertilization treatment consisting mixture biosolids...
Abstract Mesophyll conductance ( g m ) determines the diffusion of CO 2 from substomatal cavities to site carboxylation in chloroplasts and represents a critical limiting factor photosynthesis. In this study, we evaluated average effect sizes different environmental constraints on Populus spp., forest tree model. We collected raw data 815 A-C i response curves 26 datasets estimate , using single curve-fitting method alleviate method-related bias. performed meta-analysis assess effects...
