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 ...

The effects of acoustic misclassification on cetacean species abundance estimation [PDF]
, 2013 This work was funded through the Natural Environment Research Council and SMRU Ltd.To estimate the density or abundance of a cetacean species using acoustic detection data, it is necessary to correctly identify the species that are detected.

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.

The influence of land drainage on the abundance and species composition of small mammals
Theriologia Ukrainica, 2022 The article is devoted to the research on the abundance and species composition of small mammals in the territory of central Ukraine (Cherkasy, Poltava, and Kyiv oblasts) affected by land development by drainage.

Direct evidence that density-dependent regulation underpins the temporal stability of abundant species in a diverse animal community [PDF]
, 2014 The authors thank the ERC (project no. BioTIME 250189) and the Royal Society for funding.To understand how ecosystems are structured and stabilized, and to identify when communities are at risk of damage or collapse, we need to know how the abundances of

Species richness, abundance and phenology of fungal fruit bodies over 21 years in a Swiss forest plot [PDF]
, 2001 Fungal fruit bodies were surveyed on a plot area of 1500 m2 from 1975¿99 (excluding 1980¿83) in the fungal reserve La Chaneaz in western Switzerland. Fruit bodies were identified and counted on a weekly basis.

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 ...

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.

A meta-analysis of fauna and flora species richness and abundance in plantations and pasture lands [PDF]
, 2010 We conducted a systematic global review of differences between timber plantations and pasture lands in terms of animal and plant species richness and abundance, and assessed the results using meta-analysis techniques.
