Comparing spatial null models for brain maps [PDF]
NeuroImage, 2021 Technological and data sharing advances have led to a proliferation of high-resolution structural and functional maps of the brain. Modern neuroimaging research increasingly depends on identifying correspondences between the topographies of these maps ...

Null models for gene enrichment in plasmids. [PDF]
Proc Natl Acad Sci U S A, 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 ...

A null model for microbial diversification [PDF]
Proceedings of the National Academy of Sciences, 2017 SignificanceWhen evolutionary histories of closely related microorganisms are reconstructed, the lineages often cluster into visibly recognizable groups. However, we do not know if these clusters represent fundamental units of bacterial diversity, such as “species,” nor do we know the nature of evolutionary and ecological forces that are responsible ...

Journal of Threatened Taxa, 2017 The co-occurrence patterns of fish communities in the littorals of three lagoons of the Orinoco River floodplain in Venezuela were studied during four hydrological phases: low, rising, high and falling waters, from 2008–2009, using null models.

Hyper abundant mesopredators and bird extinction in an Atlantic forest island
Zoologia (Curitiba), 2009 Islands can serve as model systems for understanding how biological invasions affect native species. Here we examine the negative effects of mesopredator mammals on bird richness at Anchieta Island, an 826 ha offshore island in the coast of Brazil ...

Size overlap in intertidal decapod communities along the chilean coast
Scientia Marina, 2020 The intertidal crustaceans on the Chilean coast are characterized by high diversity and niche specialization. The present study applied a size overlap null model for intertidal decapod communities at four different sites on the Chilean coast. The results
