Article
Full-text available
The seeds of most plant species are dispersed by multiple mechanisms. Whether functional traits mediate positive correlations or negative correlations (trade-offs) between different dispersal mechanisms has important consequences for ecological and evolutionary dynamics. We investigate how traits affect wind-driven seed dispersal through the air an...

Aims How seed dispersal distance is related to various factors is a major challenge for seed ecologists. However, there are different answers as to which factor is most important in determining wind dispersal distance. This study is to quantitatively describe the relationship between various factors and primary wind dispersal distance of winged dia...

A portable wind tunnel, which was designed for investigating the seed dispersal by wind, was built by the Institute of Applied Ecology, Chinese Academy of Sciences and the Experimental Center of Desert Forest, Chinese Academy of Forestry. The wind tunnel was designed to satisfy the requirements of investigations at diaspore, plant individual and la...

Seed availability is critical for vegetation restoration of bare patches in desertified grassland. Many studies explain seed availability by seed arrival or retention, however, no conclusions are universally applicable. Eleven bare patches, ranging from 80 m2 to 500 m2, were selected in semi-arid desertified grassland of Inner Mongolia in northeast...

Seed dispersal by wind is one of the most important dispersal mechanisms in plants. The key seed trait affecting seed dispersal by wind is the effective terminal velocity (hereafter "terminal velocity", V t), the maximum falling speed of a seed in still air. Accurate estimates of V t are crucial for predicting intra-and interspecific variation in s...
Article
Aims Understanding how diaspore (hereafter “seed”) morphology and orientation affect secondary seed dispersal by wind is important to link seed dispersal and post-dispersal processes, such as seed lodging, predation and germination. This study aims to describe the effects of seed morphology and orientation on secondary seed dispersal by wind via m...
Article
Full-text available
Hydrology is a major environmental factor determining plant fitness, and hydrological niche segregation (HNS) has been widely used to explain species coexistence. Nevertheless, the distribution of plant species along hydrological gradients does not only depend on their hydrological niches but also depend on their seed dispersal, with dispersal eith...
Article
Seed dispersal plays an important role in population dynamics in agricultural ecosystems, but the effects of surrounding vegetation height on seed dispersal and population connectivity on the landscape scale have rarely been studied. Understanding the effects of surrounding vegetation height on seed dispersal will provide important information for...
Article

Aim Habitat loss and fragmentation impose high extinction risk upon endangered plant species globally. For many endangered plant species, as the remnant habitats become smaller and more fragmented, it is vital to estimate the population spread rate of small patches in order to effectively manage and preserve them for potential future range expansio...

Article
Spontaneous hybridization in ex situ conservation facilities could potentially contaminate endangered plant species destined for the reintroduction into the wild. Despite the general recognition of the importance of such danger, studies exploring the consequences of hybridization including subsequent performance of the hybrids in comparison to the...
Article
As one of the major terrestrial ecosystems, grasslands play a vital role in the global carbon cycle. However, the estimation of carbon stock in China's grasslands still remains controversial. Using the measured data from spatial stratified sampling (including 200 sites; 400 soil profiles, 2400 soil samples in the depth of 0–100 cm, 400 above-ground...

Project
We are organizing a special issue on seed ecology for Frontiers in Ecology and Evolution. The topic is mainly focused on seed adaptation to extreme (uncommon) environments.Your contribution is welcome. https://www.frontiersin.org/research-topics/40401/seed-behavior-in-response-to-extreme-environments Please feel free to contact me if you are interested in the topic and have any question about it.
Project
We aim to quantitatively relate dispersal traits, environmental conditions and multiple dispersal mechanisms. With 10 seed morphologies (five types of heterocarpous Zygophyllum xanthoxylon and five Calligonum species), we quantify effects of plant attributes, seed traits and environmental conditions on primary and secondary seed dispersal by wind (wind-driven seed movement through the air and over the ground, respectively). We measure seed release height, seed dimensions (length, width, thickness, mass, projected area, etc.), seed terminal falling velocity, orientation of seeds after they first land, seed lift-off velocity, wind speed and ground surface roughness. We determine primary dispersal distance and secondary dispersal potential with extensive wind-tunnel experiments, and we disentangle the effects on primary and secondary dispersal with empirical and mechanistic models. The project is founded by Sino-German (CSC-DAAD) Postdoc Scholarship, from February, 2016 to July, 2017, during which I work with Prof. Frank M. Schurr in Institute of Landscape and Plant Ecology, University of Hohenheim, Germany.
