Soilborne pathogens can contribute to diversity maintenance in tree communities through the Janzen‐Connell effect, whereby pathogenic reduction of seedling performance attenuates with distance from conspecifics. By contrast, arbuscular mycorrhizal fungi (AMF) have been reported promote performance; however, it is unknown whether this also dependent. Here, we investigate dependence presence both and AMF. In a subtropical forest south China, conducted four‐year field census four species...
Abstract The effect of biodiversity on primary productivity has been a hot topic in ecology for over 20 years. Biodiversity–productivity relationships natural ecosystems are highly variable, although positive most common. Understanding the conditions under which different emerge is still major challenge. Here, by analyzing HerbDivNet data, global survey grasslands, we show that stabilizes rather than increases plant grasslands at scale. Our results suggest species richness shifts from...
Numerous grassland experiments have found evidence for a complementarity effect, an increase in productivity with higher plant species richness due to niche partitioning. However, empirical tests of natural forests are rare. We conducted spatially explicit analysis 518 433 growth records 274 from 50-ha tropical forest plot test neighborhood complementarity, the idea that tree grows faster when it is surrounded by more dissimilar neighbors. complementarity: focal rates increased 39.8% and...
Abstract Earlier studies indicated that plant diversity influences community resistance in biomass when ecosystems are exposed to perturbations. This relationship remains controversial, however. Here we constructed grassland communities test the relationships between species and productivity under control experimental drought conditions. Species richness was not correlated with either constant conditions or However, lower production were more resistant stress than those productive. Our...
The negative effect of soil pathogens on seedling survival varies considerably among conspecific individuals, but the underlying mechanisms are largely unknown. For variation between heterospecifics, a common explanation is Janzen‐Connell effect: density dependence in due to specialized aggregating hosts. We test whether an intraspecific exists, i.e., chances one population's seedlings surrounded by different population increase with genetic difference, spatial distance, and trait...
Conspecific negative density dependence (CNDD) is often involved in explaining the maintenance of species diversity forest communities given that it may suppress common species. Recent studies, contrast, suggested CNDD had a stronger effect on rare than and thus shaped current tree abundance pattern. However, this finding was obtained mainly tropical mixed results also occurred similar area. In addition, experimental test role soil biota maintaining relationship rare. study, two parallel...
NaYF4 nanoparticles (NPs) were synthesized by a facile solvothermal approach using polyvinylpyrrolidone (PVP) as surfactant. The NPs doped into P3HT:PCBM blend to fabricate inverted polymer bulk heterojunction (BHJ) solar cells. dependence of device performance on the weight ratio in film was investigated. results showed that open-circuit voltage apparently enhanced doping NPs/PVP composites active layer while maintaining short-circuit current density and fill factor, leading an increase...
We demonstrate a facile way to fabricate high spectrum selectivity hybrid ultraviolet photodetectors with poly(N-vinylcarbazole) and 2D TiO2 nanobowl (NB) array as the electron donor acceptor, respectively. The highly ordered NB was prepared by using colloidal templates of polystyrene (PS) spheres. response peak devices centered at 330 nm full width half maximum 38.5 nm, which is very close ultraviolet-B band (UVB, 280–320 nm).

Density dependence has long been considered an important mechanism for species coexistence in forests. Density‐dependent processes can be mechanisms driving differences diversity across latitudes. Here we examined the decline strength of density with increasing latitude, and particularly how affected both conspecifics heterospecifics. Conspecific individuals within a were predominantly aggregated at three different latitudes study sites China. The percentage declined spatial scale growth...
Because the frequency of heterospecific interactions inevitably increases with species richness in a community, biodiversity effects must be expressed by such interactions. However, little is understood how affect ecosystem productivity because rarely are functioning experiments spatially explicitly manipulated. To test effect on productivity, direct evidence neighborhood interaction needed. In this study we conducted detailed spatial design to investigate whether and promote primary...
Community compensatory trend (CCT) is thought to facilitate persistence of rare species and thus stabilize composition in tropical forests. However, whether CCT acts over broad geographical ranges still question. In this study, we tested for the presence negative density dependence (NDD) three forests along a tropical-temperate gradient. Inventory data were collected from forest communities located different latitudinal zones China. Two widely used methods test NDD at community level. The...
