Estimating Species Abundance from Occurrence [PDF]

The American Naturalist, 2000
The number of individuals, or the abundance, of a species\ud in an area is a fundamental ecological parameter and a\ud critical consideration when making management and conservation decisions (Andrewartha and Birch 1954; Krebs\ud 1978; Gaston 1994; Caughley and Gunn 1996).

Attenuation of species abundance distributions by sampling [PDF]

Royal Society Open Science, 2015
Quantifying biodiversity aspects such as species presence/ absence, richness and abundance is an important challenge to answer scientific and resource management questions. In practice, biodiversity can only be assessed from biological material taken by surveys, a difficult task given limited time and resources.

Garden and landscape-scale correlates of moths of differing conservation status: significant effects of urbanization and habitat diversity [PDF]

, 2014
Moths are abundant and ubiquitous in vegetated terrestrial environments and are pollinators, important herbivores of wild plants, and food for birds, bats and rodents.

Comprehensive Evaluation of RNA and DNA Viromic Methods Based on Species Richness and Abundance Analyses Using Marmot Rectal Samples

mSystems, 2022
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.

Diversity of stored-product beetles at the rice warehouses in Mataram City and Central Lombok Regency, Indonesia

Jurnal Ilmiah Pertanian, 2023
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]

Journal of Animal Ecology, 2006
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

Frontiers in Microbiology, 2020
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 ...

Waterbird community changes in the Wilderness Lakes, South Africa (Part 1 of 3): Herbivores and omnivores

Koedoe: African Protected Area Conservation and Science, 2023
Global and regional degradation and loss of aquatic systems can negatively affect wetland-dependent waterbirds. The Wilderness Lakes Complex in South Africa, which incorporates the Wilderness Ramsar site, supports populations of 68 waterbird species ...
