DOM and microbes

We are excited to have our study just published in Nature Communications. This study is led by Dr. Ang Hu, and focuses on the associations between dissolved organic matter (DOM) and microbes. Briefly, we developed a new approach by considering the ecological networks of DOM and microbes and null models to quantify their interactions. We then [...] Read more

Microbes on mountainsides

We just have a review paper published on line by New Phytologist. In this review, we summarise the literature of mountainous microbes and provide perspetives for future studies. We appreciate a lot of colleagues in helping and supporting our studies on mountainsides in the past 15 years, and are excited to see this piece of work as a milestone for [...] Read more

Evolution of Thaumarchaeota

Ammonia-oxidizing archaea (AOA) of the phylum Thaumarchaeota are widespread across a great variety of ecosystems and play a significant role in global nitrogen and carbon cycling. Since the first reports of the non-extremely archaea from marine water column [1, 2], there are increasingly advancements in our understanding of the ecology and [...] Read more

Effect-size qSIP

How does microbial species performance respond to environmental changes? Such a simple question is challenging to answer with quantitative measurements, especially for complex communities. We just got a paper published on line in Ecology to help in answering this question. Based on stable isotope labelling of DNA, we propose a new approach namely [...] Read more

Quantify primary assembly processes

Niche and dispersal processes are the two primary assembly processes, and it remains a challenging goal to distangle the relative importance of these two processes underlying biological communities. It is likely that niche and dispersal processes are not mutually exclusive but constitute the end points of a continuum. Based on multiple null mudels, [...] Read more

Predict functional diversity

Our recent study, led by postdoc researcher FĂ©lix, examines the functional genes of stream microbes on the mountainsides in Norway, Spain and China, and further predicts the continental-scale variations of stream functional diversity under future climate change. Our findings indicate that climate change increases the functional diversity of [...] Read more

Snows of Mt. Kilimanjaro

We just finished a field trip to Tanzania in Feb 1 - March 25, and surveyed the lakes across Tanzania and the streams along the elevational gradient on Mt. Kilimanjaro. This trip is fruitful with valuable samples now returned. Such an international field trip is also memorable due to the unique time window during which the COVID-19 epidemic was [...] Read more

Beta diversity on mountainsides

Community variation (i.e. beta diversity) along geographical gradients is of substantial interest in ecology and biodiversity reserves in the face of global changes. However, the generality in beta diversity patterns and underlying processes remains less studied across trophic levels and geographical regions. We documented beta diversity patterns [...] Read more
