“…Leaf distribution across strata in tree stands is determined by canopy dominant light transmittance. The most frequent tree species in the study area-P. sylvestris-has loose crowns, allowing higher light availability beneath its crowns than the other species [24,63,64]. Similarly, a small LAI to BA ratio for P. sylvestris in mature tree stands was reported by Bauer [65].…”

Research Highlights: We evaluated influence of alien and native trees and shrubs on stand leaf area index to basal area ratio, indicating that both groups provide similar amounts of foliage. Background and Objectives: Foliage traits determine tree species effect on understory light availability. Direct comparisons of understory light availability due to different foliage traits of tree species are conducted less often at the stand level. We hypothesized that light availability is driven by canopy leaf area, and alien species contribution to canopy foliage will be similar to native species due to analogous patterns of biomass allocation in tree species. Materials and Methods: We studied forests dominated by alien and native tree species in Wielkopolski National Park (Western Poland). We measured light availability using the LAI-2200 canopy analyzer (Li-Cor Inc., Lincoln, NE, USA) and we calculated leaf area index (LAI) in 170 stands using published models of foliage biomass and data on specific leaf area. Results: Our study confirmed an impact of LAI on light availability in the understory layer. Analyzing the proportion of contribution to stand LAI and basal area (BA) we found that most alien species did not differ in LAI to BA ratio from native species. The exception was Prunus serotina Ehrh., with a LAI to BA ratio higher than all native and alien trees. However, the highest LAI to BA ratios we found were for the alien shrub Cotoneaster lucidus Schltdl. and native shrubs of fertile broadleaved forests. Conclusions: Our study showed that alien species contribution to shading the understory is comparable to native species, with the exception of P. serotina due to its dominance in the higher shrub canopy strata where it exhibits different patterns of biomass allocation than native trees. Our study explained that invasive tree species impact on light availability in forest ecosystems is mainly mediated by the increased quantity of foliage, not by more effective LAI to BA ratio.Light interception by canopy is one of the most important drivers of understory functioning. High light availability determines understory productivity [26][27][28]. It is also one of the most important drivers of plant species composition [24,29,30], as well as soil biota [21]. It is also crucial for regeneration of canopy species [31][32][33]. Usually minimum light availability for sapling survival is higher for pioneer tree species than mid-and late-successional tree species [25,34,35]. This value varies light availability under open sky by around 5%-10% [32,36,37].Despite numerous studies confirming light availability limitation by alien species, few studies compare their influence with functionally analogous native competitors. Most studies on invasive plants focused rather on conditions favoring their establishment than their impacts [33,38,39]. For that reason we aimed to assess how much leaf area index (LAI, m 2 of leaves m −2 stand area) determines light availability on the forest floor and whether alien, invasive trees contribute mo...

“…The relative abundance of Q. rubra in Polish forests is increasing over time (Woziwoda, Potocki, et al, 2014).

Consumer‐mediated indirect interaction with a native plant lowers the fitness of an invasive competitor

Seed dispersal is a primary driver, via propagule pressure, of biological invasions. In animal‐dispersed plants, theory predicts that indirect ecological interactions at the neighbourhood scale may determine landscape‐scale patterns of seed dispersal and predation, and thus invasion. Indirect interactions in seed dispersal may arise between two plant species if shared seed dispersal agents adjust their foraging decisions to the relative frequencies of co‐occurring seeds. We used seed‐tracking experiments and empirically parameterized simulations to test the hypothesis that an indirect interaction between two plant species, mediated by scatterhoarding rodents that both consume and disperse seeds, affects recruitment of an invasive tree. We predicted that acorns of Quercus rubra (invasive in Central Europe) would experience higher caching (and therefore survival) rates when they co‐occurred with native Quercus petraea than when they occurred in isolation, that Q. petraea acorns would survive at lower rates with Q. rubra relative to isolation, and that this interaction would facilitate Q. rubra seedling recruitment in Q. petraea forests. Contrary to expectations, the presence of Q. petraea reduced caching of Q. rubra acorns, and co‐occurrence with Q. rubra increased caching of Q. petraea. Thus, a rodent‐mediated indirect interaction may be slowing rather than facilitating the Q. rubra invasion. However, our simulations indicate that the magnitude of this indirect interaction will change nonlinearly as Q. rubra becomes more dominant on the landscape, and that the pace of invasion will accelerate as the alien species is released from the rodent‐mediated effect of Q. petraea. Synthesis. The presence of native Quercus petraea decreases recruitment rates of Quercus rubra, and consequently, slows down the invasion process. The strong dependence of pairwise interactions on the presence of a third‐party species emphasizes the role of indirect interactions in the invasion processes.

“…Similarly, alien tree species, often better adapted to harsh environmental conditions, could provide high amounts of nutrients for the soils of novel ecosystems. However, due to their habitat transformation ability, their introduction could be a threat to surrounding forests (Jagodziński, Dyderski, Rawlik, & Banaszczak, 2015;Jagodziński, Dyderski, Horodecki & Rawlik, 2018). Establishment of mixed stands, with both forecrop and target tree species could combine both aims.…”

No in‐depth studies covering litter decomposition were previously conducted on afforested postmining sites despite the importance of litter decomposition on soil formation, especially in degraded areas. We aimed to compare leaf litter decomposition rates of 14 tree species growing in mixed stands on a postmining spoil heap, and to compare their decay rates with those obtained in pure stands of tree species that are very often planted in postmining areas. The study was conducted on the Bełchatów Lignite Mine spoil heap, central Poland. We studied litter decomposition rates over 5 years using the litterbag method. Leaf litter decomposition rates (k constants; yr−1) after 5 years of the experiment were arranged from highest to lowest as follows: Prunus serotina (1.04), Alnus glutinosa (0.86), Fraxinus excelsior (0.81), Ulmus laevis (0.73), Acer pseudoplatanus (0.68), Populus tremula (0.63), Populus × canadensis (0.59), Betula pendula (0.54), Populus nigra ‘Italica’ (0.38), Quercus rubra (0.36), Pinus sylvestris (0.34), Robinia pseudoacacia (0.34), Fagus sylvatica (0.25), and Quercus robur (0.22). Decomposition rates increased with Mg, Ca, and summed Mg + Ca + P + K contents in freshly fallen leaves (%). All species‐specific decomposition rates were higher in mixed than in Scots pine stands. Half of them were also higher than in pure stands of other tree species. Our results indicate that tree species composition could significantly affect the physiochemical properties of upper soil horizons on reclaimed areas. Based on these findings, we recommend planting high share of not only A. pseudoplatanus, A. glutinosa, and U. laevis but also F. sylvatica and Q. robur in stands on postmining spoil heaps, because mixed stands can accelerate soil development more than pure stands.
