Aim The main aims were to determine:(a) the relative contribution of species replacement
and richness difference from components to overall taxonomic (TDβ) and functional (FDβ) …

Understanding patterns of species richness at broad geographic extents remains one of the
most challenging yet necessary scientific goals of our time. Many hypotheses have been …

Aim Different hypothesis have been proposed to explain differences in species richness
among islands. However, few studies have attempted to compare the explanatory power of …

Abstract Aim The Mediterranean Basin is recognized for its high levels of species richness,
rarity and endemicity. Our main aim was to evaluate the relative effects of environmental and …

Abstract The Iberian Peninsula is recognized for its high levels of species richness, rarity
and endemicity. Our main aim was to study biogeographic patterns of spiders in coastal …

Common species have a greater effect on observed geographical patterns of species
richness than do rare ones. Here we present a theory of the relationship between individual …

Dryocosmus kuriphilus (Hymenoptera: Cynipidae) is a global invasive gall wasp and a pest
of chestnuts (Castanea spp.). A study of the Chalcidoidea parasitoid community of D …

One major challenge in parasitology and epidemiology is determining whether the richness
of parasitic and infectious diseases simply tracks host diversity or is largely determined by …

Some structural characters, such as wing venation, have been used in odonates to
differentiate taxa. In Cordulegaster boltonii, a species widely distributed throughout the …

The conversion and degradation of natural habitats has caused global declines in terrestrial
insect diversity. Conserving insect diversity has therefore gained increasing attention in …
