Using abundance data to assess the relative role of sampling biases and evolutionary radiations in Upper Muschelkalk ammonoids [PDF]
The Middle Triassic ammonoid genus Ceratites diversified spectacularly within the Germanic Muschelkalk Basin during the Anisian/Ladian (244–232 Mya). Previous studies have interpreted this diversification as a sequence of rapid, endemic radiations from a

Recovery of plant species richness during long-term fertilization of a species-rich grassland [PDF]
Nutrient enrichment of habitats (eutrophication) is considered to be one of the main causes of plant diversity decline worldwide. Several experiments have shown a rapid loss of species in the first years after fertilization started. However, little is known about changes in species richness in the long term.

The enigma of soil animal species diversity revisited: the role of small-scale heterogeneity. [PDF]
"The enigma of soil animal species diversity" was the title of a popular article by J. M. Anderson published in 1975. In that paper, Anderson provided insights on the great richness of species found in soils, but emphasized that the mechanisms ...

Social wasps can be used as ecological indicators. However, the diversity of species of this group in Minas Gerais State, Brazil, is poorly studied, especially in anthropized environments.

Mammal predator and prey species richness are strongly linked at macroscales [PDF]
Predator-prey interactions play an important role for species composition and community dynamics at local scales, but their importance in shaping large-scale gradients of species richness remains unexplored.

Facilitation beyond species richness [PDF]
AbstractFacilitation studies have previously focused on the effects of plant–plant interactions on species richness and, more recently, on functional traits or phylogenetic aspects. Little is known, however, about the simultaneous effects that facilitation have on overall biodiversity, jointly considering taxonomic, functional and phylogenetic ...

Can species richness be maintained in logged endemic Acacia Heterophylla forests (Reunion Island, Indian Ocean) ? [PDF]
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 ...

Evaluating Multiple Arthropod Taxa as Indicators of Invertebrate Diversity in Old Fields [PDF]
Biodiversity, often quantified by species richness, is commonly used to evaluate and monitor the health of ecosystems and as a tool for conservation planning. The use of one or more focal taxa as surrogates or indicators of larger taxonomic diversity can

Biodiversity loss may decrease the resistance of ecosystems to disturbance. While many studies have tested the effects of species richness on the ability of communities to resist disturbance, few have considered the role of species evenness.
