Variability in species richness and guild structure in two species-rich grasslands
Folia Geobotanica et Phytotaxonomica, 1995It has been suggested that variation in the proportion of species in guilds (=guild proportionality) indicates community structuring by guilds in biotic communities. This hypothesis was tested on a subthermophilous grassland and a mesotrophic meadow at a scale of 0.09 m2 based on a five-year data set.

Abstract One of the most famous features of tropical rain forests is their extreme species richness which has impressed scientists ever since the earliest explorations (Chapter 1). Some species are common, but most are rare: as has been described above (p.

The evolution of word use has contributed to the rich vocabulary of English in general and has made scientific English a particularly dynamic tool. However, some changes in word use have costs as well as benefits, and involve unintended consequences.

Estimating Species Richness: The Importance of Heterogeneity in Species Detectability
Ecology, 1998Estimating species richness (i.e., the actual number of species present in a given area) is a basic objective of many field studies carried out in community ecology and is also of crucial concern when dealing with the conservation and management of biodiversity.

Summary A number of species richness estimators have been developed under the model that individuals (or sampling units) are sampled with replacement. However, if sampling is done without replacement so that no sampled unit can be repeatedly observed, then the traditional estimators for sampling with replacement tend to overestimate richness for ...

Species Richness and Diversity
2012This chapter reviews the literature on species richness and species diversity. The two concepts are closely related, but are not synonyms. Species richness is estimated dividing the number of species by the geographic area. On the other hand, species diversity is a function of the number of species present (i.e.

Effects of woody plant species richness on mammal species richness in southern Africa
Journal of Biogeography, 2009AbstractAim To determine the relationship between the species richness of woody plants and that of mammals after accounting for the effect of environmental variables.Location Southern Africa, including Namibia, South Africa, Lesotho, Swaziland, Botswana, Zimbabwe, and part of Mozambique.Methods We used a comprehensive dataset including the species ...

Historical biogeography, ecology and species richness
Trends in Ecology & Evolution, 2004Ecology and historical (phylogeny-based) biogeography have much to offer one another, but exchanges between these fields have been limited. Historical biogeography has become narrowly focused on using phylogenies to discover the history of geological connections among regions.

On Age and Species Richness of Higher Taxa
The American Naturalist, 2014Many studies have tried to identify factors that explain differences in numbers of species between clades against the background assumption that older clades contain more species because they have had more time for diversity to accumulate. The finding in several recent studies that species richness of clades is decoupled from stem age has been ...

Limits to species richness in terrestrial communities
Ecology Letters, 2018AbstractAre communities limited by biotic interactions, or are they random draws from regional species pools? One way to tell is to compare total species counts in geographic regions to average counts in ecological samples falling within those regions. If species richness is limited regionally, then the relationship should be curvilinear even in a log ...
