Randomizing growing networks with a time-respecting null model. [PDF]
Physical Review E, 2017 Complex networks are often used to represent systems that are not static but grow with time: People make new friendships, new papers are published and refer to the existing ones, and so forth.

Better null models for assessing predictive accuracy of disease models [PDF]
PLOS ONE, 2021 Null models provide a critical baseline for the evaluation of predictive disease models. Many studies consider only the grand mean null model (i.e. R 2 ) when evaluating the predictive ability of a model, which is insufficient to convey the predictive power of a model.

Journal of Ecology, 2019 Plant‐fungal interactions are important for plant community assembly, but quantifying these relationships remains challenging. High throughput sequencing of fungal communities allows us to identify plant‐fungal associations at a high level of resolution,

Frontiers in Microbiology, 2021 Microbial communities are composed of many rare species and a few abundant species. Considering the disproportionate importance of rare species for ecosystem functioning, it is important to understand the mechanisms structuring the rare and abundant ...

Null models for gene enrichment in plasmids [PDF]
Proceedings of the National Academy of Sciences, 2021 The recent article by Che et al. (1) presents an analysis of a dataset of 14,029 plasmids. I enjoyed the paper but have some concerns about its analysis. While it is clear that more conjugative plasmids carry antimicrobial resistance (AMR) genes, it is unclear whether this is simply because conjugative plasmids tend to carry more genes in general ...

Global Change Biology, 2018 Understanding the joint effect of multiple drivers of environmental change is a key scientific challenge. The dominant approach today is to compare observed joint effects with predictions from various types of null models.

Measuring nestedness: A comparative study of the performance of different metrics
Ecology and Evolution, 2020 Nestedness is a property of interaction networks widely observed in natural mutualistic communities, among other systems. A perfectly nested network is characterized by the peculiarity that the interactions of any node form a subset of the interactions ...

Ecology and Evolution, 2021 Aim The mechanisms underlying the maintenance of biodiversity remain to be elucidated. Taxonomic diversity alone remains an unresolved issue, especially in terms of the mechanisms of species co‐existence.

Royal Society Open Science, 2021 The effectiveness of behavioural interventions in conservation often depends on local resource users' underlying social interactions. However, it remains unclear to what extent differences in related topics of information shared between resource users ...
