A null model for Pearson coexpression networks. [PDF]

open access: yesPLoS ONE, 2015
Gene coexpression networks inferred by correlation from high-throughput profiling such as microarray data represent simple but effective structures for discovering and interpreting linear gene relationships.

Null modes effect in Rossby wave model [PDF]

open access: goldNonlinear Processes in Geophysics, 2004
The problem of the null-modes existence and some particularities of their interaction with nonlinear vortex-wave-like structures is discussed. We show that the null-modes are fundamental elements of nonlinear wave fields.

Optimized null model for protein structure networks. [PDF]

open access: yesPLoS ONE, 2009
Much attention has recently been given to the statistical significance of topological features observed in biological networks. Here, we consider residue interaction graphs (RIGs) as network representations of protein structures with residues as nodes ...

The Role Transition of Dietary Species Richness in Modulating the Gut Microbial Assembly and Postweaning Performance of a Generalist Herbivore

open access: yesmSystems, 2021
When facing a food shortage, generalist herbivores can respond by expanding their dietary species richness (DSR) to maximize energy collection, regardless of whether forages are preferred or not.

Dispersal Limitation Expands the Diversity of Coral Microbiome Metacommunity in the South China Sea

open access: yesFrontiers in Marine Science, 2021
The coral microbiome is one of the most complex microbial biospheres. However, the ecological processes shaping coral microbiome community assembly are not well understood. Here, we investigated the abundance, diversity, and community assembly mechanisms

Spatial scale changes the relationship between beta diversity, species richness and latitude [PDF]

open access: yesRoyal Society Open Science, 2018
The relationship between β-diversity and latitude still remains to be a core question in ecology because of the lack of consensus between studies. One hypothesis for the lack of consensus between studies is that spatial scale changes the relationship ...

Oilseed Rape Shares Abundant and Generalized Pollinators with Its Co-Flowering Plant Species

open access: yesInsects, 2021
Mass-flowering crops, such as Oilseed Rape (OSR), provide resources for pollinators and benefit from pollination services. Studies that observe the community of interactions between plants and pollinators are critical to understanding the resource needs ...
