Global abundance estimates for 9,700 bird species

open access: yesProceedings of the National Academy of Sciences of the United States of America, 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.

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

open access: yesJurnal 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

Road Zone Effects in Small-Mammal Communities

open access: yesEcology and Society, 2009
Our study focused on the putative effects of roads on small-mammal communities in a high desert region of southern Utah. Specifically, we tested whether or not roads create adjacent zones characterized by lower small- mammal densities, abundance, and ...

Exploring the Niche Concept in a Simple Metaorganism

open access: yesFrontiers 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 ...

Improving species distribution model predictive accuracy using species abundance: Application with boosted regression trees

open access: yes, 2020
Auxiliary information in the form of species abundance is frequently available as part of data collected for ecological investigations, yet when modeling distributions of species over large regions, species presence (and sometimes absence) are typically ...

Understory epiphytic pteridophytes along altitudinal gradients on opposite slopes in the Atlantic Forest

open access: yesRodriguésia, 2023
Gradual climatic changes caused by mountains’ altitudinal variation promote alterations in the structure of ecological communities. Environmental changes are also expected according to the slope’s position in relation to the sea.

A quantitative review of abundance-based species distribution models

open access: yesbioRxiv, 2021
The contributions of species to ecosystem functions or services depend not only on their presence in a given community, but also on their local abundance.

Clonal growth and plant species abundance [PDF]

open access: yesAnnals 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.

Abundance and diversity of soil arthropods and fungi in shelterbelts integrated with pastures in the central tablelands of New South Wales, Australia

open access: yesJournal of Forest Science, 2012
Shelterbelts are important for the sustainability of agriculture because they provide a variety of benefits to farmers and the society. Several published papers demonstrate that integration of shelterbelts with agroecosystems offers positive outcomes ...

Waterbird community changes in the Wilderness Lakes, South Africa (Part 2 of 3): Shorebirds

open access: yesKoedoe: African Protected Area Conservation and Science, 2023
Globally, many shorebirds, particularly the smaller migratory waders are declining, which can be attributed to multiple factors throughout their ranges.
