Data from: Invasive herbaceous respond more negatively to elevated ozone concentration than native species
<p>Aim: Many studies show that increase in ground-level ozone (O<sub>3</sub>) has adverse effects on plant growth. Due to high phenotypic plasticity, invasive species is considered to be more adaptable to elevated O3 than native species. This idea is only tested by the very limited studies comparing invasive weeds with crops. However, whether it holds remains unclear when comparing invasive species with their co-occurring native species in natural systems.</p> <p>Location: China</p> <p>Methods: We performed an open-top chamber experiment growing six congeneric pairs of invasive and native species with and without competition under ambient (approximately 43 ppb) and elevated O<sub>3</sub> (approximately 89 ppb) concentrations to test whether the growth responses to elevated O<sub>3</sub> concentrations differ between invasive and native species.</p> <p>Results: Our results revealed that elevated O<sub>3</sub> had a significant negative effect on both invasive and native species. In particular, elevated O<sub>3</sub> reduced the aboveground biomass and damaged the leaves of invasive species significantly more than those of native species.</p> <p>Main conclusions: Our study indicates that elevated O<sub>3</sub> concentration has a stronger adverse effect on invasive species than on native species. Therefore, increasing O<sub>3</sub> pollution might suppress plant invasion, and thus invasive species might expand their distribution more easily to the area with lower O<sub>3</sub> pollution in the future.</p>
Data from: Functionally diverse tree stands reduce herbaceous diversity and productivity via canopy packing
<p><b>1. </b>There is extensive experimental evidence for the importance of biodiversity in sustaining ecosystem functioning. However, such experiments typically prevent immigration by continuously removing non-target species, thereby questioning the generality of these findings to real-world ecosystems. This is particularly true in forest ecosystems where understorey herbaceous species are key biodiversity components but are usually weeded in tree diversity experiments. Consequently, little is known about how tree diversity influences the natural dynamics of understorey herbaceous layers.</p> <p><b>2.</b> We conducted a three-year non-weeded tree diversity experiment composed of eight woody species differing widely in plant economic strategies. We examined how the functional diversity and identity of tree species mixtures drive the temporal dynamics of understorey productivity, functional diversity, and composition through canopy packing.</p> <p><b>3.</b> Tree mixtures with high functional diversity experienced increased canopy packing over time, thereby decreasing understorey productivity and diversity. Furthermore, herbaceous communities were dominated by species with functional traits typical of low-light conditions (lower community-weighted mean (CWM) of maximum plant height, but larger CWM of specific leaf area) in response to increased canopy packing.</p> <p><b>4.</b> Our results provide mechanistic insights into the role of tree functional diversity in shaping the dynamics of biomass, functional diversity, and composition of the understorey herbaceous layer during the early successional period. It is expected that the effects of tree functional diversity would also be relevant over time due to the increasing usage of canopy space. This study highlights the significance of natural community processes in determining the effects of tree diversity on the temporal dynamics of previously neglected ecosystem structures and functioning.</p>

Data related to article: Shrubs exhibit competitive interactions with herbaceous plants and shape community assemblage and functional composition in alpine western Himalaya
<p>To understand the interaction between dominant shrubs and herbacous communities in the alpine region of western Himalaya, a field study was conducted along the elevation gradient (3500-5000 masl). During the field survey, we have collected population data, plant functional trait data and soil physico-chemical data from shrub undercanopy and adjacent open habitats. Relative Interaction Index and L0g ratio were calculated using the population data. Further, plant functional traits data and soil physicochemical data were utilised to understand the functional comoposition and resource availability occuring in the contrasting habitats.</p>
