Introduction
I'm interesting in species diversity and community structure of island faunas, interaction among species and biodiversity change after habitat fragmentation, particularly ants and birds.
Community ecology, island biogeography, myrmecology and conservation biology are my broad interests.

1. Biodiversity change in anthropogenically transformed habitats is often nonrandom, yet the nature and importance of the different mechanisms shaping community structure are unclear. Here, we extend the classic Theory of Island Biogeography (TIB) to account for nonrandom processes by incorporating species traits and phylogenetic relationships into...
Incorporating imperfect detection when estimating species richness has become commonplace in the past decade. However, the question of how imperfect detection of species affects estimates of functional and phylogenetic community structure remains untested. We used long‐term counts of breeding bird species that were detected at least once on islands...
To explore the impact of island area and isolation on multiple dimensions of ant biodiversity (taxonomic, phylogenetic and functional diversity) and the underlying processes of community assembly on islands. Thousand Island Lake, Zhejiang, China, created by dam construction in 1959. Ants. We sampled ants on 33 islands, built a species‐level phyloge...
Habitat loss and fragmentation reduce biodiversity and alter species composition in local communities. β diversity describes the variation in species composition between or among communities in fragmented landscapes and has two components: species turnover and nestedness. In this study, we assessed β diversity of ant assemblages on 24 island fragme...
1. The Equilibrium Theory of Island Biogeography postulates that larger and closer islands support higher biodiversity through the dynamic balance of colonization and extinction processes. The negative diversity-isolation (i.e., the distance to the mainland) relationship is derived based on the assumption that the mainland is the only source pool f...
Understanding how community phylogenetic and functional structures change over succession has gained increasing attention during the last decades, but the lack of long-term time-series data has limited our understanding of the patterns and mechanisms of these changes. This is especially the case for forest communities. Here we used an exceptionally...
The equilibrium theory of island biogeography predicts the positive species–area relationship and the negative species–isolation relationship, resulting in higher species richness on large and close islands. Unlike species richness, soundscape diversity integrates sound from various sources (e.g. biophony, geophony and anthrophony). However, how so...
Habitat fragmentation impacts seed dispersal processes that are important in maintaining biodiversity and ecosystem functioning. However, it is still unclear how habitat fragmentation affects frugivorous interactions due to the lack of high-quality data on plant-frugivore networks. Here we recorded 10,117 plant-frugivore interactions from 22 reserv...
Many of the choices humans make with regard to infrastructure, urban planning and other phenomena have impacts that will last thousands of years. This can readily be seen in modern cities in which contemporary streets run along street grids that were laid out thousands of years prior or even in which ancient viaducts still play a role. However, rar...
Rodents are ubiquitous seed predators in nature and their size-related seed choice plays an important role in the plant’s community structure. However, to understand how size-related seed predation by rodents affects plant recruitment, it is fundamental to predict seeds and seedling response to rodent predation. We assessed the interactive effects...
This dataset is the latest and most complete one on species traits of Chinese birds.
The 17 traits included body mass, body length, bill length, wing length, tail length, tarsus length, primary diet, clutch size, egg size, egg volume, nest site, nest type, flocking status, migrant status, endemic status, biogeographic distribution and the number o...
Aims: China has a total of 1,445 bird species and is the one of the countries with the richest bird diversity in the world. Species traits strongly determine the species’ ability to persist in a variety of environments and are fundamental to ecological, evolutionary and conservational research. Therefore, it is important to collecting data on life-...
Density‐dependent non‐monotonic species interactions are important in maintaining ecosystem stability and function, but empirical evidences are still rare. Rodents, as both seed dispersers and seed predators, have dual effects on plant regeneration and may result in non‐monotonic rodent‐plant interactions. According to the non‐monotonic models, the...
To explore the spatial patterns and influencing factors of ground ants species diversity in the Thousand Island Lake, China, we surveyed ground ants using pitfall traps, leaf litter extraction and hand collecting on 33 islands in May to August 2017 and 2018. We divided all ground ants into predator ants or omnivore ants according to their diet. We...
Abstract Background China has a relative high degree of endemism of birds due to its large area, diversified topography, and varied climates and habitats. Among the 77 Chinese endemic birds, 29 species are classified as threatened according to the officially released China Biodiversity Red List in 2015. Chinese endemic birds should be the focus of...
1. Habitat loss and fragmentation often leads to defaunation of large-bodied mammals , and their loss could trigger release from top-down control or food resource competition for small mammal seed dispersers, which in turn may affect the effectiveness of seed dispersal by altering the number of dispersed seeds or the manner in which they are disper...
China is one of the countries with the richest bird biodiversity in the world. Among the 1372 Chinese birds, 146 species are considered threatened and three species are regionally extinct according to the officially released China Biodiversity Red List in 2015. Here, we conducted the first extensive analysis to systematically investigate the patter...
Beta diversity describes the variation in species composition among communities within a region and it is determined by two antithetic processes: species turnover (or species replacement), and nestedness (or difference in richness). Beta-diversity partitioning aims to separate these two processes when examining species composition among communities...
Island biogeography theory is an important part of community ecology, and its core process is species turnover, which is determined by species colonization and extinction. A large number of studies have shown that community dynamics of many biotic taxa can be affected by their dispersal abilities. Our study explored the effects of dispersal abiliti...
Questions
Questions (2)
I used glmer.nb() to form a model, but how do I know if the model is correct for my data? How to do the model validation?
I used pitfall traps to collect ant on islands, thus, different size of islands contain different number of pitfall traps. Ants are really super-population, the abundance data based on individuals is unreliable.
I know the code dist.chao() in CommEcol package in R can be used to calculate the estimated taxonomic beta diversity that takes into account "rare" species. And it can be done by using frequency data (i.e., the number of pitfall traps that an ant species was caught in).
Now I have phylogenetic tree and functional traits of all the ants I caught. I wonder how to calculate phylogenetic and functional estimated beta diversity also using the frequency data. I checked the BetaDiversity() function in entropart package. But it requires abundance data.
Anyone have an idea about that? Really appreciate!

To understand the the processes and mechanisms of ant community assembly on different habitat islands using functional and phylogenetic methods.
To assess the dynamics of rodent-plant interactions after habitat fragmentation
By exploring the architecture of plant-pollinator insect network and plant-frugivore bird network on the fragmented land-bridge islands and nearby mainland sites in the Thousand Island Lake region, this project will examine the effects of habitat fragmentation on plant-animal mutualistic networks, and how species' trait and phylogeny affect the network structure.
