Sampling biases shape our view of the natural world

Alice Hughes, Keping Ma, Mark Costello, John Waller, Pieter Provoost, Qinmin Yang, Chaodong Zhu, Huijie Qiao & Michael Orr
Spatial patterns of biodiversity are inextricably linked to their collection methods, yet no synthesis of bias patterns or their consequences exists. As such, views of organismal distribution and the ecosystems they make up may be incorrect, undermining countless ecological and evolutionary studies. Using 742 million records of 374,900 species, we explore the global patterns and impacts of biases related to taxonomy, accessibility, ecotype, and data type across terrestrial and marine systems. Pervasive sampling and observation...

The ability to disperse large seeds, rather than body mass alone, defines the importance of animals in a hyper-diverse seed dispersal network

Lisa Ong, Kim McConkey & Ahimsa Campos-Arceiz
1. Large-bodied animals play irreplaceable roles in seed dispersal, partly due to their capacity to disperse large seeds. Understanding this role at a community level has been limited by the paucity of network studies that include large vertebrates, and the almost complete absence of studies including synzoochoric dispersers. Synzoochoric dispersers can disperse seeds disproportionately large for their body size, potentially overlapping the roles of large-bodied animals. A comprehensive network, inclusive of large vertebrates and synzoochorous...

Type specimen information of Primula longistyla

Xing-Da Ma, Wen-Guang Wang, Ji-Pu Shi & Jian-Yong Shen
Primula longistyla, a new species of Primulaceae is described and submitted to the Nordic Journal of Botany. This species is similar to P. densa, but clearly differs in its leaves, corollas and styles. In this dataset, we provide details of the type specimens of the new species.

Morphological and behavioural differences facilitate tropical butterfly persistence in variable environments

Cheng Wenda, Shuang Xing, Akihiro Nakamura & Timothy C. Bonebrake
1. The thermal biology of ectotherms largely determines their abundance and distributions. In general, tropical species inhabiting warm and stable thermal environments tend to have low tolerance to cold and variable environments, which may restrict their expansion into temperate climates. However, the distribution of some tropical species does extend into cooler areas such as tropical borders and high elevation tropical mountains. Behavioural and morphological differences may therefore play important roles in facilitating tropical species to...

Assessing candidate DNA barcodes for Chinese and internationally traded timber species

Jian-Lin Hu, Xiu-Qin Ci, Zhi-Fang Liu, Eleanor E. Dormontt, John G. Conran, Jie Li & Andrew J. Lowe
Accurate identification of species from timber is an essential step to help control illegal logging and forest loss. However, current approaches to timber identification based on morphological and anatomical characteristics have limited species resolution. DNA barcoding is a proven tool for plant species identification, but there is a need to build reliable reference data across broad taxonomic and spatial scales. Here, we construct a species barcoding library consisting of 1,550 taxonomically diverse timber species from...

Hydraulic prediction of drought-induced plant dieback and top-kill depends on leaf habit and growth form

Ya-Jun Chen, Brendan Choat, Frank Sterck, Phisamai Maenpuen, Masatoshi Katabuchi, Shu-Bin Zhang, Kyle Tomlinson, Rafael Oliveira, Yong-Jiang Zhang, Kun-Fang Cao & Steven Jansen
Hydraulic failure caused by severe drought contributes to aboveground dieback and whole-plant death. The extent to which dieback or whole-plant death can be predicted by plant hydraulic traits has rarely been tested among species with different leaf habits and/or growth forms. We investigated 19 hydraulic traits in 40 woody species in a tropical savanna and their potential correlations with drought response during an extreme drought event during the El Niño–Southern Oscillation in 2015. Plant hydraulic...

Analysis of acoustic index against temperature and barometric pressure

Catharina Karlsson, Harold Tay, Paul Yambun & Alice Hughes
1. New low-cost options to long-term acoustic monitoring in terrestrial ecology are becoming increasingly available. However, integration of acoustic stations with sensors for logging of additional data, such as temperature and barometric pressure is rare. Separate environmental loggers often come at a cost of > US$100 whereas the same sensors for use with microprocessors come at a cost between US$. 1-15 The cost savings integration entails as well as the crucial need for the recording...

Retention fraction of 15N-labelled deposited ammonium and nitrate in forests

Geshere Abdisa Gurmesa, Ang Wang, Shanlong Li, Shushi Peng, Wim De Vries, Per Gundersen, Philippe Ciais, Oliver L Phillips, Erik Hobbie, Weixing Zhu, Knute Nadelhoffer, Yi Xi, Edith Bai, Tao Sun, Dexiang Chen, Wenjun Zhou, Yiping Zhang, Yingrong Guo, Jiaojun Zhu, Lei Duan, Dejun Li, Keisuke Koba, Enzai Du, Guoyi Zhou, Xingguo Han … & Yunting Fang
The impacts of enhanced nitrogen (N) deposition on global forest carbon (C) sink and other ecosystem services may depend on whether N is deposited in reduced (mainly as ammonium) or oxidized forms (mainly as nitrate) and the subsequent fate of each. However, the fates of the two key reactive N forms and its contribution to forest C sink is unclear. We conducted ecosystem-scale paired 15N-labelling experiments in nine forests across China to quantify N retention...

Spatial autocorrelation shapes liana distribution better than topography and host tree properties in a subtropical evergreen broadleaved forest in SW China

Bai Xiao-Long, Liu Qi, Mohandass Dharmalingam, Cao Min, Wen Han-Dong, Chen Ya-Jun, Gupta Sunil Kumar, Lin Lu-Xiang & Zhang Jiao-Lin
Lianas are an important component of subtropical forests, but the mechanisms underlying their spatial distribution patterns have received relatively little attention. Here, we selected 12 most abundant liana species, constituting up to 96.9% of the total liana stems, in a 20-ha plot in a subtropical evergreen broadleaved forest at 2,472 – 2,628 m elevation in SW China. Combining data on topography (convexity, slope, aspect, and elevation) and host trees (density and size) of the plot,...

Trivalvaria tomentosa (Annonaceae), a new species from Southeast Yunnan, China

Bine Xue, Jian-Wu Li, Jun-Jie Liao, Ming-Zhong Mo, Yun-Hong Tan & You-Sheng Chen
Trivalvaria tomentosa sp. nov. is herein described from Yunnan Province in China. It is easily distinguished from all previously described Trivalvaria species by having tomentose twigs, petioles, abaxial surface of the leaves, sepals and petals. A detailed description for the new species, along with line drawings, photographs, as well as morphological comparisons with similar species, are provided. A phylogenetic analysis was conducted to confirm the placement of this new species within Trivalvaria.

cpDNA sequecnes of Themeda triandra and Heteropogon contortus

Yingying Chu
To investigate the historical continuity of grassy biomes in southwest China, we examined the biogeographies and evolutionary histories of two widespread and dominant C4 grasses, Themeda triandra and Heteropogon contortus, in Yunnan and southern Sichuan provinces, using chloroplast DNA markers in combination with climate data.

Fossil-informed models reveal a Boreotropical origin and divergent evolutionary trajectories in the walnut family (Juglandaceae)

Qiuyue Zhang, Richard Ree, Nicolas Salamin, Yaowu Xing & Daniele Silvestro
Temperate woody plants in the Northern Hemisphere have long been known to exhibit high species richness in East Asia and North America and significantly lower diversity in Europe, but the causes of this pattern remain debated. Here, we quantify the roles of dispersal, niche evolution, and extinction in shaping the geographic diversity of the temperate woody plant family Juglandaceae (walnuts and their relatives). Integrating evidence from molecular, morphological, fossil, and (paleo)environmental data, we find strong...

Site-specific impacts of a major hurricane on alpha and beta diversity in tropical forest seedling communities

Samantha Worthy, Vanessa Rubio, Kirstin Staiger, Boris Ngouajio, Jie Yang & Nathan Swenson
Large scale disturbances are known to impact the alpha and beta diversity of communities. However, whether these disturbances increase or decrease diversity is often debated. The goal of this study was to quantify how the diversity of the seedling community was impacted within and across elevation in the El Yunque forest of Puerto Rico following a major hurricane. We tested two alternative hypotheses, that hurricanes are relatively more homogenizing or non-homogenizing forces, by quantifying changes...
