Unveiling global species abundance distributions. [PDF]
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.

Estimating species abundance from occurrence [PDF]
The number of individuals, or the abundance, of a species in an area is a fundamental ecological parameter and a critical consideration when making management and conservation decisions (Andrewartha and Birch 1954; Krebs 1978; Gaston 1994; Caughley ...

Species Abundance Patterns in Complex Evolutionary Dynamics [PDF]
An analytic theory of species abundance patterns (SAPs) in biological networks is presented. The theory is based on multispecies replicator dynamics equivalent to the Lotka-Volterra equation, with diverse interspecies interactions.

Functional Traits Are Good Predictors of Tree Species Abundance Across 101 Subtropical Forest Species in China [PDF]
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

Attenuation of species abundance distributions by sampling [PDF]
Quantifying biodiversity aspects such as species presence/ absence, richness and abundance is an important challenge to answer scientific and resource management questions.

The Alien Plants That Threaten South Africa’s Mountain Ecosystems
The six major mountain ranges in South Africa support critically important ecosystem services—notably water production—and are rich in biodiversity and endemism.

Viral metagenomics is the most powerful tool to profile viromic composition for a given sample. Different viromic methods, including amplification-free ones, have been developed, but choosing them for different purposes requires comprehensive benchmarks.

Beetles, the order Coleoptera, are post-harvest rice product pests that cause severe quantitative and qualitative damage. Therefore, the diversity of pest beetles found in rice warehouses is essential because it leads to pest management by detecting and

On plotting species abundance distributions [PDF]
Summary There has been a revival of interest in species abundance distribution (SAD) models, stimulated by the claim that the log‐normal distribution gave an underestimate of the observed numbers of rare species in species‐rich assemblages. This led to the development of the neutral Zero Sum Multinomial distribution (ZSM) to better fit the observed ...

Exploring the Niche Concept in a Simple Metaorganism
Organisms and their resident microbial communities - the microbiome - form a complex and mostly stable ecosystem. It is known that the composition of the microbiome and bacterial species abundances can have a major impact on host health and Darwinian ...
