Animals, 2018 Broad-scale abundance estimates of the southern hairy-nosed wombat population use a proxy measure based on counting the number of active burrows, which is multiplied by an index of ‘wombats/active burrow’.

Frontiers in Plant Science, 2023 Changes in tree species composition are one of the key aspects of forest succession. In recent decades, significant changes have occurred in the tree species composition of subtropical forests in China, with a decrease in coniferous trees and an increase

Aquatic Hemiptera of Wisconsin [PDF]
, 2017 About 59,000 aquatic Hemiptera were collected in Wisconsin, most of them in the last 15 years. These include three species of Belostomatidae, 48 species of Corixidae, one species of Naucoridae, four species of Nepidae, nine species of Notonectidae, and ...

SPECIES-AREA RELATIONSHIP FOR POWER-LAW SPECIES ABUNDANCE DISTRIBUTION [PDF]
International Journal of Biomathematics, 2012 We studied the mathematical relations between species abundance distributions (SADs) and species-area relationships (SARs) and found that a power-law SAR can be generally derived from a power-law SAD without a special assumption such as the "canonical hypothesis".

Species abundance patterns in an ecosystem simulation studied through Fisher's logseries [PDF]
, 2010 We have developed an individual-based evolving predator-prey ecosystem simulation that integrates, for the first time, a complex individual behaviour model, an evolutionary mechanism and a speciation process, at an acceptable computational cost.

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 ...

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
