PLoS Comput Biol 17(9):Įditor: Nicola Segata, University of Trento, ITALY Applying BEEM-Static to a large public dataset of human gut microbiomes, we were able to identify multiple stable equilibria with distinct ecological properties.Ĭitation: Li C, Av-Shalom TV, Tan JWG, Kwah JS, Chng KR, Nagarajan N (2021) BEEM-Static: Accurate inference of ecological interactions from cross-sectional microbiome data. In addition, BEEM-Static was robust to various types of noises using statistical filters to identify and remove data points violating its assumptions. Our benchmarking results showed that BEEM-Static inferred presence and directionality of interactions accurately, while correlation based methods had performance slightly better than random guesses. We developed an expectation-maximization algorithm (BEEM-Static) that can infer directed interaction networks from cross-sectional data based on an ecological model. Widely used correlation based approaches for inferring interactions from cross-sectional microbiome sequencing data are not able to predict the directionality of interactions, and their results may not be interpretable. Applying BEEM-Static to a large public dataset of human gut microbiomes (n = 4,617) identified multiple stable equilibria that better reflect ecological enterotypes with distinct carrying capacities and interactions for key species.Ĭharacterizing the ecological interactions among microbial members is an important step towards understanding the structure and function of diverse microbial communities. In addition, BEEM-Static can tolerate a high fraction of samples (up to 40%) being not at steady state or coming from an alternate model. Benchmarking against 10 state-of-the-art correlation based methods showed that BEEM-Static can infer presence and directionality of ecological interactions even with relative abundance data (AUC-ROC>0.85), a task that other methods struggle with (AUC-ROC<0.63). The method exhibits robustness to violations in model assumptions by using statistical filters to identify and remove corresponding samples. We present an expectation-maximization algorithm (BEEM-Static) that can be applied to cross-sectional datasets to infer interaction networks based on an ecological model (generalized Lotka-Volterra). Leveraging cross-sectional microbiome datasets for unravelling ecological structure in a scalable manner thus remains an open problem. With rapid adoption of next-generation sequencing for studying microbiomes, data-driven inference of microbial interactions based on abundance correlations is widely used, but with the drawback that ecological interpretations may not be possible. When you hit the 'Search' button, the site gives information about the person's current and previous places of employment.The structure and function of diverse microbial communities is underpinned by ecological interactions that remain uncharacterized. Visit and input the person's current address on the search bar. You can find out where a person works using the address lookup feature. All you have to do is visit, enter the correct information in the search bar, and hit the “Search“ button. You can use your neighbor's name, phone number, or email address to find their address. Note that with only one name, you get a lot of entries, and you need to keenly go through them to find the desired one. You can find a person at by conducting searches using only their first names.
