“…It also con rms Marshall's theory on clonal integration of ramets, which refers to the sharing of materials or resources between ramets: photosynthetic products are transported by rhizomes from the source -in this case from leaves of vegetative shoots, to the target -fruiting shoots (Marshall 1990). Similar results were found in a study on biomass and leaf traits of twelve understory herbaceous plants -in most cases, generative plants had lower speci c leaf area than vegetative plants (Jagodziński et al 2016). Contrary to results of Depauw et al (2020), we found greater plant height decreases under more closed canopy in recent than in ancient forests, however, this could be a species-speci c reaction to changes in light conditions.…”

Background: Multi-purpose use of forests in a sustainable way forces a recognition of how alien woody species introduction in forests with different land use history affect native plants other than trees. Lingonberry Vaccinium vitis-idaea is an important understory component of temperate and boreal forests and provider of valuable non-wood forest products. Here we studied effects of land use changes and introduction of Northern red oak Quercus rubra on lingonberry in a mesic Scots pine (Pinus sylvestris) forests (in central Poland). We measured lingonberry cover, height of shoots, biomass of stems and leaves, and fruit productivity. Shoots were collected within 200 research plots located in recent and ancient Scots pine forests, with and without Q. rubra.Results: We found that V. vitis-idaea reached lower cover, aboveground biomass and fruit production in recent than ancient forests and in forests with than without Q. rubra. The fruit production in recent pine forest was only 2% of that reported in ancient pine forest, and V. vitis-idaea did not reproduce generatively in forests with Q. rubra. Biomass and carbon sequestration of V. vitis-idaea in forests with alien (invasive) tree decreased by 75% compared to ancient pine forest. Effects were also clear at the individual shoot level – in less suitable conditions we found taller heights and higher biomass allocation into stems than foliage. Biomass allocation in fruiting and non-fruiting shoots in pine forests was also different – less of the dry biomass of fruiting shoots was allocated to leaves than to stems.Conclusions: In the age of high interest in ecosystem services and discussions about usage of alien tree species as alternatives in forest management, our results clearly indicate disruption of ecosystem services provided by V. vitis-idaea in the presence of Q. rubra. Lingonberry benefited from the continuity of forest land use, however, regardless of land-use legacy, alien tree introduction, led to decline in abundance of species crucial for ecosystem functioning. Therefore, to maintain valuable native species and for conservation of ecosystem services delivery, we suggest limiting the introducing Q. rubra in areas with abundant V. vitis-idaea, especially in forests with continuous forest land-use history.

“…For example Baroloto et al (2010) recommended sampling each species at least once in every plot. Even this level of effort may under-represent the variation that can occur in trait values between leaves on the same plant (Shipley 1995), between individuals of the same species (Albert et al 2010) and throughout the growing season (Pierce, Running & Walker 1994;Gunn et al 1999;Jagodzi nski et al 2016).

Leaf dry matter content is better at predicting above‐ground net primary production than specific leaf area

et al. 2017

Summary Reliable modelling of above‐ground net primary production (aNPP) at fine resolution is a significant challenge. A promising avenue for improving process models is to include response and effect trait relationships. However, uncertainties remain over which leaf traits are correlated most strongly with aNPP. We compared abundance‐weighted values of two of the most widely used traits from the leaf economics spectrum (specific leaf area and leaf dry matter content) with measured aNPP across a temperate ecosystem gradient. We found that leaf dry matter content (LDMC) as opposed to specific leaf area (SLA) was the superior predictor of aNPP (R2 = 0·55). Directly measured in situ trait values for the dominant species improved estimation of aNPP significantly. Introducing intraspecific trait variation by including the effect of replicated trait values from published databases did not improve the estimation of aNPP. Our results support the prospect of greater scientific understanding for less cost because LDMC is much easier to measure than SLA.

“…TB was used as an overall plant fitness measure reflecting space filled by the species, and is also claimed to be a good measure of plant fitness (Younginger et al 2017). We chose three leaf traits: SLA reflecting resource use efficiency within foliage (Wright et al 2004;Díaz et al 2016), PLA reflecting filling of space by foliage (Jagodziński et al 2016) and LAR as a measure of whole plant investment in foliage efficiency. These factors are known to vary across soil fertility and light availability gradients.…”

One of the most important sources of invasiveness is species’ functional traits and their variability. However there are still few studies on invasive tree species traits conducted along resource gradients that allow for a comparison of acquisitive and conservative strategies. We aimed to assess the differences in trait variation among native alien conservative and alien acquisitive tree species along resource availability gradients (soil fertility and light availability) and to assess the traits variability of the species studied along resources availability gradients. Our study compared invasive tree species in Europe (Prunusserotina Ehrh. Quercusrubra L. and Robiniapseudoacacia L.) with their native competitors (Acerpseudoplatanus L. A.platanoides L. Quercuspetraea (Matt.) Liebl. and Fagussylvatica L.). The study was conducted on 1329 seedlings and saplings collected in a system of 372 study plots in W Poland. For each individual we assessed leaf stem and root mass ratios total biomass leaf area ratio specific leaf area and projected leaf area. Two invasive species (P.serotina and R.pseudoacacia) represented a more acquisitive strategy than native species – along litter pH and light availability gradients these species had higher leaf mass fraction specific leaf area and leaf area ratio. In contrast Q.rubra had the highest total biomass and root mass fraction. Alien species usually had higher coefficients of variation of studied traits. This suggests that relatively high projected leaf area as a way of filling space and outcompeting native species may be reached in two ways – biomass allocation to leaves and control of leaf morphology or by overall growth rate. High variability of invasive species traits also suggests randomness in seedling survival which similarly to the neutral theory of invasion highlights the necessity of including randomness in modelling biological invasions.
