“…Meteorological data were interpolated for each plot from the nearest eight monitoring stations of the Federal Office of Meteorology and Climatology (MeteoSwiss) as described in Braun et al (2017b). The resulting daily averages were used in the regression analysis or as input to the hydrological model Wasim-ETH (Schulla, 2013).…”

Excess deposition of the mineral nutrient nitrogen (N) is a serious threat for European forests. Its effect on foliar nutrient concentrations of Fagus sylvatica, along with other predictors, was analyzed in the present study which bases on 30 year's observation data in 74 forest monitoring plots in Switzerland. The data include gradients in soil chemistry, climate, nitrogen (N) deposition, and ozone concentration. This long-term forest monitoring study shows that foliar concentrations of phosphorus (P), magnesium (Mg), and potassium (K) decreased over time. Current foliar P concentrations indicate acute P deficiency, assessed both from the concentration and the N:P ratio thresholds. In addition, also the relation between N deposition and foliar concentrations of N and P changed over time. Initially, the N concentrations were positively and the P concentrations not correlated with N deposition. Today, N concentrations are negatively and P strongly negatively related, suggesting a progressive N saturation. Interactions between N deposition and soil chemistry suggest an impaired uptake of K and P at higher N loads. The decline of foliar Mg concentrations seems to be a result of soil acidification mediated by N deposition. Additionally, ozone impaired foliar P uptake. We could observe an increase in leaf weight over time while there was no time trend in P and K mass per leaf. This could be interpreted as a dilution effect but detailed regression analysis argues against the dilution hypothesis. Overall, the changing relation between N deposition and foliar N and P support the nitrogen saturation hypothesis.

“…The objective of the present paper was to disentangle the contribution of these possible factors, along with the role of edaphic predictors. Growth data for the study have been presented by Braun et al (2017b). They show a marked decrease in stem increment, both on the basis of individual tree measurements and on plot surface.…”

“…Different tree species also show divergent growth responses to global-change drivers due to their different autecological characteristics (e.g., competitive ability, drought sensitivity; Bosela et al, 2016;Charru, Seynave, Hervé, Bertrand, & Bontemps, 2017;Mette et al, 2013). In addition, interactive effects of multiple drivers acting simultaneously upon trees might cause tree growth responses to differ from those in single-factor studies, highlighting the need for multi-factor studies (Braun, Schindler, & Rihm, 2017;Laubhann et al, 2009).…”

“…Previous studies have explored how global-change drivers affect tree growth, but mostly on a restricted geographical scale (Bauwe, Jurasinski, Scharnweber, Schröder, & Lennartz, 2016;Braun et al, 2017;Ibáñez, Zak, Burton, & Pregitzer, 2018;Martinez-Vilalta, Lopez, Adell, Badiella, & Ninyerolas, 2008). Tree growth studies covering larger geographical scales and taking into account interactions between global-change drivers at the same time (e.g., Laubhann et al, 2009;Solberg et al, 2009) are relatively scarce.…”

Forecasting the growth of tree species to future environmental changes requires a better understanding of its determinants. Tree growth is known to respond to global‐change drivers such as climate change or atmospheric deposition, as well as to local land‐use drivers such as forest management. Yet, large geographical scale studies examining interactive growth responses to multiple global‐change drivers are relatively scarce and rarely consider management effects. Here, we assessed the interactive effects of three global‐change drivers (temperature, precipitation and nitrogen deposition) on individual tree growth of three study species (Quercus robur/petraea, Fagus sylvatica and Fraxinus excelsior). We sampled trees along spatial environmental gradients across Europe and accounted for the effects of management for Quercus. We collected increment cores from 267 trees distributed over 151 plots in 19 forest regions and characterized their neighbouring environment to take into account potentially confounding factors such as tree size, competition, soil conditions and elevation. We demonstrate that growth responds interactively to global‐change drivers, with species‐specific sensitivities to the combined factors. Simultaneously high levels of precipitation and deposition benefited Fraxinus, but negatively affected Quercus’ growth, highlighting species‐specific interactive tree growth responses to combined drivers. For Fagus, a stronger growth response to higher temperatures was found when precipitation was also higher, illustrating the potential negative effects of drought stress under warming for this species. Furthermore, we show that past forest management can modulate the effects of changing temperatures on Quercus’ growth; individuals in plots with a coppicing history showed stronger growth responses to higher temperatures. Overall, our findings highlight how tree growth can be interactively determined by global‐change drivers, and how these growth responses might be modulated by past forest management. By showing future growth changes for scenarios of environmental change, we stress the importance of considering multiple drivers, including past management and their interactions, when predicting tree growth.

“…A large number of published studies have already revealed the physiological characteristics and expansion mechanisms of S. alterniflora based on laboratory work (Deng et al, 2006;Hu et al, 2015;Shi et al, 2007;Wang et al, 2015;Gu & Zhang, 2009;Zhao et al, 2007;. These studies demonstrated that the expansion of S. alterniflora is influenced by elevation, climate, soil salinity, inundation duration, pH, and many other variables could influence, but previous studies only focus on the single-variable and ignore the interactive effects of multiple variables (Braun, Schindler, & Rihm, 2017;Daniel, Hubert, GertJan, & Wim, 2009). Although studies have recognized the importance of interactions, fewer researches have systematically identified interactions among variables (Liu et al, 2018).…”

Aim Global change seriously threatens the salt marsh ecosystem, while it remains unclear how S . will respond to climate change and sea level rise. Here, we investigated interactions among variables and identified the impacts of climate change, sea level rise, and their interactions on the distribution of Spartina alterniflora . Location Northern Chinese coast and Southern Chinese coast. Taxon Spartina alterniflora Loisel. Methods With global sensitivity analysis, we determined interactions among variables and their relative importance to the distribution of S. alterniflora . Integrating the Venn's four‐set diagram, we built ecological niche models under current and three future scenarios to identify pure, shared, and coupling effects of climate change and sea level rise on the distribution of S. alterniflora . Results Mean diurnal range (Bio02) and Elevation were the two most critical variables controlling the distribution of S. alterniflora on the Chinese coast, and interactions among variables of the northern coast were much greater than that of the southern coast. Habitats change was mainly caused by pure effects of climate change, except habitats reduction on the southern coast. Pure effects of sea level rise were low, but it can influence habitats change through shared and coupling effects from complex interactions with climate change. Interactions of climate change and sea level rise can drive habitats change, and the changed habitats caused by shared and coupling effects were mainly distributed the areas near the landward side. Main conclusions Our research suggests paying attention to interactions among variables when calculating the relative importance of explanatory variables. Identifying pure, shared, and coupling effects of climate change and sea level rise for the distribution of S. alterniflora will provide scientific references for assessing the risk of similar coastal species.
