Null models for gene enrichment in plasmids. [PDF]

open access: yesProc 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 niche for null models in adaptive resource management. [PDF]

open access: yesEcol Evol, 2022
AbstractAs global systems rapidly change, our collective ability to predict future ecological dynamics will become increasingly important for successful natural resource management. By merging stakeholder objectives with system uncertainty, and by adapting actions to changing systems and knowledge, adaptive resource management (ARM) provides a rigorous

A null model for microbial diversification [PDF]

open access: yesProceedings of the National Academy of Sciences, 2017
Significance When 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

First Description of Invertebrate Benthic Fauna in the Middle Zone of the Loa River (Chile)

open access: yesZoodiversity, 2023
Aquatic insect communities in inland waters of Chile are characterised by the presence of certain species depending on water quality, but there is little information on statistical ecology in the structure of insect communities.

The “Null-A” superintegrability for monomial matrix models

open access: yesAnnals of Physics, 2023
We find that superintegrability (character expansion) property persists in the exotic sector of the monomial non-Gaussian matrix model, with potential $\Tr X^r$, in pure phase, where the naive partition function $\langle 1 \rangle$ vanishes. The role of the (anomaly-corrected) partition function is played by $\left\langleχ_ρ\right\rangle$ -- the Schur ...

Community structure of benthic invertebrates in the Allipén River basin, North Patagonia, Araucania region (38º S, Chile)

open access: yesBrazilian Journal of Biology, 2021
One of the biological indicators most used to determine the health of a fluvial ecosystem are the benthic macroinvertebrates. The presence of recurrent species in a wide gradient of latitudes, dominates the biogeographic pattern of the benthic ...

Random sampling associated with microbial profiling leads to overestimated stochasticity inference in community assembly

open access: yesFrontiers in Microbiology, 2022
Revealing the mechanisms governing the complex community assembly over space and time is a central issue in ecology. Null models have been developed to quantitatively disentangle the relative importance of deterministic vs.
