Unveiling global species abundance distributions. [PDF]
Nat Ecol Evol, 2023 AbstractWhether 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 (gSADs) of 39 taxonomic classes of eukaryotic organisms from 1900 to 2019.

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 ...

Bracken: estimating species abundance in metagenomics data
PeerJ Computer Science, 2016 Metagenomic experiments attempt to characterize microbial communities using high-throughput DNA sequencing. Identification of the microorganisms in a sample provides information about the genetic profile, population structure, and role of microorganisms within an environment.

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.

Global abundance estimates for 9,700 bird species [PDF]
Proceedings of the National Academy of Sciences, 2021 Significance For the fields of ecology, evolutionary biology, and conservation, abundance estimates of organisms are essential. Quantifying abundance, however, is difficult and time consuming. Using a data integration approach integrating expert-derived abundance estimates and global citizen science data, we estimate the global population of ...

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 ...

Functional Traits Are Good Predictors of Tree Species Abundance Across 101 Subtropical Forest Species in China [PDF]
Frontiers in Plant Science, 2021 What causes variation in species abundance for a given site remains a central question in community ecology. Foundational to trait-based ecology is the expectation that functional traits determine species abundance. However, the relative success of using

Measuring β‐diversity with species abundance data [PDF]
Journal of Animal Ecology, 2015 Summary In 2003, 24 presence–absence β‐diversity metrics were reviewed and a number of trade‐offs and redundancies identified. We present a parallel investigation into the performance of abundance‐based metrics of β‐diversity. β‐diversity is a multi‐faceted concept, central to spatial ecology. There are multiple metrics available to quantify it: the

Clonal growth and plant species abundance [PDF]
Annals of Botany, 2014 Both regional and local plant abundances are driven by species' dispersal capacities and their abilities to exploit new habitats and persist there. These processes are affected by clonal growth, which is difficult to evaluate and compare across large numbers of species.

Conserving the abundance of nonthreatened species
Conservation Biology, 2018 Abstract 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 result in the loss of vast numbers of individuals, biomass, and ...
