Article
Spontaneous urban plants (SUPs) constitute an important component of urban vegetation, but they have received less attention in urban biodiversity and ecological research, especially at the regional scale. We comprehensively reviewed the occurrence records of SUPs in 59 major cities across China's geographical regions. We systematically analyzed fl...

Earthworms dominate the invertebrate biomass in soils. Although the effects of living earthworms on soil functioning have been extensively studied, the ecological impacts of earthworm cadavers on soil microbiota remain unclear. In a 10-weeks laboratory incubation experiment, we monitored the influence of decomposing earthworm cadavers on the divers...

Aim The introduction of exotic plants can both increase (homogenize) and decrease (differentiate) floristic similarity between areas. We have a poor understanding of the degree to which plant species introductions tend to homogenize or differentiate floras, and relevant studies covering large spatial extent are scarce. China has been heavily invade...

The introduction of alien species may be influenced by the phylogenetic structure of the native assemblage, while at the same time altering that structure. Understanding these effects sheds light on both the factors influencing naturalization of introduced species and their impacts. Considering regional angiosperm assemblages across China, we ask t...

Elevation changes create gradients in abiotic factors, which in turn affect soil erosion and carbon cycling. However, how elevation changes control soil ecological processes through temperature and the mechanism that affects the carbon cycle remain unclear. Therefore, we have studied the distribution of temperature, bulk density (BD), soil pH, mean...

Wetlands provide a habitat for the symbiosis of multiple plants and play a significant role in global N2O emissions. The metabolic traits and effects on microorganisms, which regulate the conversion of nitrogen to N2O, varies with plant species. The frequent occurrences of cyanobacterial blooms in wetlands can also have a positive or negative effec...
Article
Urban ecosystems feature intense anthropogenic activities and environmental stressors that filter species with varying life-history traits. The traits therefore provide an essential aspect to understanding how species respond to urban environments. We conducted this study in Chongqing, a mountainous city in southwestern China, and tested the hypoth...
Article
Restoring forests has recently received considerable attention in the context of sequestering carbon and supporting biodiversity. Although considering alien species as a tool for natural forest restoration still remains controversial, harnessing alien species when they are already present in an ecosystem might result in overall benefits for nature...
Article
Cities have become the main abodes for people, and landscape plants with their notable influence on quality of life, are important components of the urban ecosystem. The need to explore the climatic suitability and sustainability of landscape plants is especially relevant due to globalization and climate change. Nevertheless, this research area is...
Article
Masting is a common reproductive strategy regulating seedling regeneration in many perennial plant species. The evolutionary origins and functional benefits of masting have been explained by well‐supported hypotheses relating to economies of scale of seed production. Nevertheless, our understanding of the potential costs of masting for the plant se...

Abstract Declining forests usually face uncertain regeneration dynamics and recovery trajectories, which are challenging to forest management. In this study, we investigated the decline pattern of Castanopsis fargesii and examined the effects on conspecific seedling regeneration. We found that 61.45% of adult individuals were in decline and the sma...
Article
Microplastics are recognized as an emerging contaminant worldwide. Although microplastics have been shown to strongly affect organisms in aquatic environments, less is known about whether and how microplastics can affect different taxa within a soil community, and it is unclear whether these effects can cascade through soil food webs. By conducting...

Litter decomposition, a fundamental process of nutrient cycling and energy flow in freshwater ecosystems, is driven by a diverse array of decomposers. As an important component of the heterotrophic food web, meiofauna can provide a trophic link between leaf‐associated microbes (i.e., bacteria and fungi)/plant detritus and macroinvertebrates, though...
Article
Urban ecosystems can host a considerable amount of biodiversity because of the varying habitats created during urban development processes. Spontaneous vegetation is a neglected element of urban biodiversity, and the roles of a city’s natural floristic resources, geomorphic features, and topographic characteristics in shaping spontaneous plant dive...
Article
Information on the impact of dam operation on per- and polyfluoroalkyl substances (PFASs) distribution in reservoirs is very limited. In the present study, water, riparian soils and floating wastes samples were collected from the Three Gorges Reservoir, China during the storage and the discharge periods to characterize the PFASs distribution. The t...
Article
The negative consequences of increased urbanization on native biological and cultural diversity have received considerable research attention. Biological and cultural diversity can be sustained by counteracting various processes of floristic homogenization and by reestablishing connections between humans and nature. However, effective instruments t...
Article
Heritage trees are recognized as elements of cultural landscapes and as keystone ecological entities in human-dominated landscapes, often bestowing high socio-cultural and ecological values. Current understanding of species distribution patterns and broad-scale species assemblages of heritage trees is limited. This study analyzed the diversity, dis...

The ‘home‐field advantage' (HFA) hypothesis suggests that litter decomposes faster beneath the plant species it derived from than beneath other species because the local adaptation of decomposer community. Yet, this hypothesis is mainly based on observations using leaf litter, and very few studies have assessed whether root litter also decomposes f...

Background and aims: The plant economics spectrum theory provides a useful framework to examine plant strategies by integrating the coordination of plant functional traits along a resource acquisition-conservation trade-off axis. Empirical evidences of this theory have been widely observed for seed plants (Spermatophyta). However, whether this the...
Article
Urbanization results in the extinction of many endemic and specialist species, and has led to the homogenization of biodiversity in global urban ecosystems. The level of biotic homogenization is viewed as an indicator of the impact of urbanization on ecosystems. Using the Jaccard similarity index (J), we investigated whether or not the urban aquati...

Today East Asia harbors many “relict” plant species whose ranges were much larger during the Paleogene-Neogene and earlier. The ecological and climatic conditions suitable for these relict species have not been identified. Here, we map the abundance and distribution patterns of relict species, showing high abundance in the humid subtropical/warm-te...

Protected areas, including nature reserves and management areas, are established for the conservation of biological diversity and protection of the associated natural and cultural resources. These objectives, however, are often in conflict with socio-economic development. We investigated the plant communities dominated by the dove tree Davidia invo...
Article
Human preferences for the species in urban greening have greatly facilitated the spread of non-native species, resulting in the homogenization of urban plant communities across spatial scales. We selected 11 major cities along the Yangtze River in China and examined the species composition in their urban plant communities. We found that China’s urb...
Article
Owing to the existence of global Pleistocene refugia, the relict and ancient component of the modern endemic flora is considerable in South-Central China. Study of these relict species helps to understand past and recent ecological processes affecting species persistence, and also provides knowledge to guide human-assisted management and conservati...

The spatial distribution of species in forest ecosystems involves the underlying ecological processes or mechanisms of population and community structure, as well as forest dynamics. Because the relative importance of these factors can shift across life history stages, assessment of local population and community structures in the context of life h...
Article
The steep and complex topography in high-elevation mountains usually generates heterogeneous habitats, where reproductive isolation in spatially discrete populations, such as unsynchronized flowering, likely occurs. Therefore, genetically differentiated populations in some cases can be expected. Patterns of genetic variation and directions of gene...
