Foliar stable nitrogen (N) isotopes (δ15N) generally reflect N availability to plants and have been used to infer about changes thereof. However, previous studies of temporal trends in foliar δ15N have ignored the influence of confounding factors, leading to uncertainties on its indication to N availability. In this study, we measured foliar δ15N of 1,811 herbarium specimens from 12 plant species collected in southern China forests from 1920 to 2010. We explored how changes in...

Considering inner and outer bark as distinctive tissues helps to disentangle the effects of bark traits on decomposition

Li Lin, Li Lin, Yao-Bin Song, Yikang Li, Leo Goudzwaard, Richard S.P. Van Logtestijn, Chenhui Chang, Rob Broekman, Jurgen Van Hal, Juan Zuo, Frank J. Sterck, Lourens Poorter, Ute Sass-Klaassen, Mariet M. Hefting & J. Hans C. Cornelissen
Revealing the ecological consequences of bark multifunctionality and its underlying traits has become a relatively new but essential focus in plant ecology. Although the enormous differences between the most crucial bark layers, i.e., inner and outer bark, in structure and functions have been widely recognized, the overall bark has been regarded as a homogenous tissue in most bark-related studies. This has led to poor knowledge on the functional independence, specialized contributions and possible linkages of...

Universal temperature sensitivity of denitrification nitrogen losses in forest soils

Haoming Yu, Yihang Duan, Jan Mulder, Peter Dörsch, Ronghua Kang, Kai Huang, Dongwei Liu, Chao Wang, Zhoutao Zheng, Zhi Quan, Feifei Zhu, Shushi Peng, Weixing Zhu, Yangjian Zhang & Yunting Fang
Soil nitrous oxide (N2O) and nitrogen gas (N2) produced from denitrification are crucial components of the global nitrogen cycle and contribute to nitrogen limitation in terrestrial ecosystems. However, the temperature sensitivity of these gaseous N losses and their underlying processes in forest soils are poorly constrained, limiting our ability to predict nitrogen cycling responses to global warming. Here, we quantify temperature sensitivities (expressed as Q10) of denitrification N2O and N2 production in 18 forest soils...

Dispersal increases spatial synchrony of populations but has weak effects on population variability: a meta-analysis

Qi Yang, Pubin Hong, Mingyu Luo, Lin Jiang & Shaopeng Wang
The effects of dispersal on spatial synchrony and population variability have been well documented in theoretical research, and a growing number of empirical tests have been performed. Yet a synthesis is still lacking. Here, we conducted a meta-analysis of relevant experiments and examined how dispersal affected spatial synchrony and temporal population variability across scales. Our analyses showed that dispersal generally promoted spatial synchrony, and such effects increased with dispersal rate and decreased with environmental correlation...

Intra- and interspecific variability of specific leaf area mitigate the reduction of community stability in response to warming and nitrogen addition

Mengjiao Huang, Shaopeng Wang, Xiang Liu, Ming Nie, Shurong Zhou & Yann Hautier
Global environmental changes are reducing the diversity and affecting the functioning of natural ecosystems as well as their ability to reliably provide ecosystem functions and services to mankind. Many studies have shown that a greater plant diversity can stabilize community productivity against environmental fluctuations. However, most of these studies focused on plant species richness, thus overlooking the potential role of functional traits in stabilizing community productivity against environmental fluctuations. Whether and how functional trait mean...

Trends in Social Mobility in Post-Revolution China (LIEPP Working Paper, n°126)

Yu Xie, Dong HAO, Zhou Xiang & Xi Song
In this paper, we study long-term trends in social mobility in the People's Republic of China since its inception in 1949, with 2 operationalizations: (1) intergenerational occupational mobility, and (2) intergenerational educational mobility. We draw on an accumulation of administrative and survey data and provide comparable estimates of these measures for birth cohorts born after 1945. To help interpret the results, we compare trends in China to those in the US for the same birth...

Specimen list and landmark coordinates for the palate of early salamanders

Jia Jia, Guangzhao Li & Ke-Qin Gao
Ecological preferences and life history strategies have enormous impacts on the evolution and phenotypic diversity of salamanders, but the yet established reliable ecological indicators hinder investigations on the paleobiology of early salamanders. Here we statistically demonstrate using geometric morphometric analysis that both the shape of the palate and many non-shape variables particularly associated with vomerine teeth are ecologically informative in early stem- and basal crown-group salamanders. The morphology of the palate is heavily impacted by...

Rapid increase in China’s industrial ammonia emissions: evidence from unit-based mapping

Yuang Chen, Qianru Zhang, Xingrui Cai, Haoran Zhang, Huiming Lin, Chaoyue Zheng, Zhanqiang Guo, Shanying Hu, Long Chen, Shu Tao, Maodian Liu & Xuejun Wang
Ammonia (NH3) is an important precursor of secondary inorganic aerosols and greatly impacts nitrogen deposition and acid rain. Previous studies have mainly focused on the agricultural NH3 emissions, while recent research has noted that industrial sources could be significant in China. However, detailed estimates of NH3 emitted from industrial sectors in China are lacking. Here we established an unprecedented high-spatial-resolution dataset of China’s industrial NH3 emissions using up-to-date measurements of NH3 and point source-level information...

From crypsis to masquerade: ontogeny changes the colour defences of a crab spider hiding as bird droppings

Long Yu, Xin Xu, Fan Li, Wei Zhou, Hua Zeng, Eunice Tan, Shichang Zhang & Daiqin Li
Selection imposed by visually-hunting predators has driven the evolution of colour-based antipredator defence strategies such as crypsis, masquerade, mimicry and aposematism. Individuals of many animals are generally considered to rely on a single type of defence strategy, but individuals of some species use multiple colour-based defences. Many animals switch between colour-based defences against visually-hunting predators during ontogeny. However, why this occurs remains poorly understood. The crab spider Phrynarachne ceylonica is an often-cited example of a...

Rivers as the largest source of mercury to coastal oceans worldwide

Maodian Liu, Qianru Zhang, Taylor Maavara, Shaoda Liu, Xuejun Wang & Peter Raymond
Mercury is a potent neurotoxic substance and accounts for 250,000 intellectual disabilities annually. Worldwide, coastal fisheries contribute the majority of human exposure to mercury through fish consumption. Recent global mercury cycling and risk models attribute all the mercury loading to the ocean to atmospheric deposition. Nevertheless, new regional research has noted that the riverine mercury export to coastal oceans may also be significant to the oceanic burden of mercury. Here we construct an unprecedented high-spatial-resolution...

High dimensionality of stoichiometric niches in soil fauna

Bing Zhang, Haozhen Chen, Mingqin Deng, Jingyi Li, Angélica González & Shaopeng Wang
The ecological niche is a fundamental concept to understand species coexistence in natural communities. The recently developed framework of the multidimensional stoichiometric niche (MSN) characterizes species niches using chemical elements in living organisms. Despite the fact that living organisms are composed by multiple elements, stoichiometric studies have so far mostly focused on carbon (C), nitrogen (N), and phosphorus (P), and therefore a quantitative analysis of the dimensionality of the MSN in living organisms is still...
