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 Félix, 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

Biodiversity on Hengduan Mountains

We are pleased to have one manuscript accepted by Science of the Total Environment. This manuscript, lead by Annika Vilmi and Wenqian Zhao in our group, is focusing on the stream communities in Hengduan Mountain biodiversity hotspot of the Tibetan Plateau. Before Annika is finishing her stay in China, she presents the main findings of this [...] Read more

Water depth and biodiversity

Understanding biodiversity patterns and the role of biotic attributes in governing these patterns remains one of the most important challenges in ecology. Here, using water depth in Lake Lugu as a typical geographical gradient, we examined the community compositions of three taxonomic groups, bacteria, diatoms and chironomids, using molecular and [...] Read more

Taxonomic scaling and biodiversity

Taxonomic scaling, such as taxonomic coverage and taxonomic resolution, could affect the biodiversity patterns and their environmental determinants. A paper, lead by Chih-Fu Yeh, an undergraduate student when he started the project, was just online on this topic titled “Elevational patterns and hierarchical determinants of biodiversity across [...] Read more
