Unveiling global species abundance distributions. [PDF]
Nat Ecol Evol, 2023 Whether most species are rare or have some intermediate abundance is a long-standing question in ecology. Here, we use more than one billion observations from the Global Biodiversity Information Facility to assess global species abundance distributions ...

Streptococcus Species Abundance in the Gut Is Linked to Subclinical Coronary Atherosclerosis in 8973 Participants From the SCAPIS Cohort. [PDF]
Circulation, 2023 BACKGROUND: Gut microbiota have been implicated in atherosclerotic disease, but their relation with subclinical coronary atherosclerosis is unclear.

Environmental fluctuations explain the universal decay of species-abundance correlations with phylogenetic distance. [PDF]
Proc Natl Acad Sci U S A, 2023 Multiple ecological forces act together to shape the composition of microbial communities. Phyloecology approaches —which combine phylogenetic relationships with community ecology— have the potential to disentangle such forces, but are often hard to ...

Nutrient supply controls the linkage between species abundance and ecological interactions in marine bacterial communities. [PDF]
Nat Commun, 2022 Nutrient scarcity is pervasive for natural microbial communities, affecting species reproduction and co-existence. However, it remains unclear whether there are general rules of how microbial species abundances are shaped by biotic and abiotic factors ...

Disentangling Environmental Effects on the Tree Species Abundance Distribution and Richness in a Subtropical Forest. [PDF]
Front Plant Sci, 2021 As a transitional vegetation type between evergreen broadleaved forest and deciduous broadleaved forest, evergreen-deciduous broadleaved mixed forest is composed of diverse plant species.

Integrating multiple sources of ecological data to unveil macroscale species abundance. [PDF]
Nat Commun, 2020 The pattern of species abundance, represented by the number of individuals per species within an ecological community, is one of the fundamental characteristics of biodiversity.

Species abundance information improves sequence taxonomy classification accuracy. [PDF]
Nat Commun, 2019 Popular naive Bayes taxonomic classifiers for amplicon sequences assume that all species in the reference database are equally likely to be observed. We demonstrate that classification accuracy degrades linearly with the degree to which that assumption ...

Bracken: estimating species abundance in metagenomics data
PeerJ Computer Science, 2016 We describe a new, highly accurate statistical method that computes the abundance of species in DNA sequences from a metagenomics sample. Bracken (Bayesian Reestimation of Abundance after Classification with KrakEN) uses the taxonomy labels assigned by ...

Disentangling the abundance–impact relationship for invasive species [PDF]
Proceedings of the National Academy of Sciences, 2019 Significance The shape (linear vs. nonlinear), direction (negative vs. positive), and strength of the relationship between invasive alien species (IAS) abundance and native species diversity determines which invaders present the greatest risk to ...

Conserving the abundance of nonthreatened species
Conservation Biology, 2018 Human modification of the environment is driving declines in population size and distributional extent of much of the world's biota. These declines extend to many of the most abundant and widespread species, for which proportionally small declines can ...
