Assessment of tree species richness as a surrogate for macrofungal species richness
Biological Conservation, 2005Abstract Attempts to understand and conserve biodiversity are hampered by a lack of information about many taxonomic groups, particularly those groups that are the most species rich. Although fungi are ubiquitous and play an important role in decomposition, nutrient cycling and nutrient uptake, little is known about fungal diversity, as fungi are ...

A comparison of methods for mapping species ranges and species richness [PDF]
Global Ecology and Biogeography, 2006 ABSTRACTAim Maps of species richness are the basis for applied research and conservation planning as well as for theoretical research investigating patterns of richness and the processes shaping these patterns. The method used to create a richness map could influence the results of such studies, but differences between these methods have been ...

Ecology Letters, 2014
Environmental heterogeneity is regarded as one of the most important factors governing species richness gradients. An increase in available niche space, provision of refuges and opportunities for isolation and divergent adaptation are thought to enhance ...

Species Richness and Evenness in Australian Birds [PDF]
The American Naturalist, 2008 Species richness and evenness are the two major components of biodiversity, but the way in which they are interrelated is a subject of contention. We found a negative relationship between the two variables for bird communities at 92 woodland sites across Australia and sought an explanation.

Randomness, Area, and Species Richness [PDF]
Ecology, 1982 Thorough censuses have been made of breeding birds on islands in Pymatuning Lake, a reservoir at the Pennsylvania—Ohio border. Analysis of the censuses yields the conclusion that for these islands the variation of the number of resident avian species with island size is that which one would expect if the birds were distributed randomly, with the ...

Global Change Biology, 2019
Large‐diameter, tall‐stature, and big‐crown trees are the main stand structures of forests, generally contributing a large fraction of aboveground biomass, and hence play an important role in climate change mitigation strategies.

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.

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 ...

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 ...
