Kin selection, species richness and community [PDF]
Biology Letters, 2013 Can evolutionary and ecological dynamics operating at one level of the biological hierarchy affect the dynamics and structure at other levels? In social insects, strong hostility towards unrelated individuals can evolve as a kin-selected counter-adaptation to intraspecific social parasitism. This aggression in turn might cause intraspecific competition

Evidence that species richness begets species richness
Journal of Biogeography, 2023 AbstractAimThe variability in regional species richness is determined by the balance between speciation, extinction, and migration, but the underlying causes of high species richness in some regions (e.g. tropics, Mediterranean ecosystems) are challenging to explain. Species richness variability may be amplified by biotic feedbacks that promote species

Predicting microbial species richness [PDF]
Proceedings of the National Academy of Sciences, 2005 Microorganisms are spectacularly diverse phylogenetically, but available estimates of their species richness are vague and problematic. For example, for comparable environments, the estimated numbers of species range from a few dozen or hundreds to tens of thousands and even half a million.

Vascular plant species richness and bioindication predict multi‐taxon species richness [PDF]
Methods in Ecology and Evolution, 2018 Abstract Plants regulate soils and microclimate, provide substrate for heterotrophic taxa, are easy to observe and identify and have a stable taxonomy, which strongly justifies their use as indicators in monitoring and conservation.

Can species richness be maintained in logged endemic Acacia Heterophylla forests (Reunion Island, Indian Ocean) ? [PDF]
, 2007 It is assumed that forests can serve multiple uses, including wood production and maintenance of high biodiversity level. We tested this hypothesis by studying eradication methods of invasive plants currently implemented in exploited endemic Acacia ...

Urbanization and Human Population Favor Species Richness of Alien Birds
Diversity, 2020 Human activities like urbanization and agriculture affect spatial biodiversity patterns. The presence and activities of humans richly benefit alien species, but native species usually decline in human-impacted areas.

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.
