1 Although much work has been done on factors patterning species trait assemblages in 2 emblematic groups such as plants and vertebrates, more remains to be done in 3 belowground invertebrate species. In particular,relationships between species traits and 4 habitat preferences are still a matter of debate. Springtails were sampled in a 5 heterogeneous landscape centered on the Sénart forest, ne...

Biologists are still trying to grasp the global dimensions of the phylum Arthropoda and its major class the Insecta, in spite of the fact that over a million species of arthropods have been described. The canopy of rain forest trees is believed by many to hold the key to the immense diversity of insects. In recent years the use of knock-down insecticides to sample insects from rain forest canop...

Terrestrial ecosystems consist of mutually dependent producer and decomposer subsystems, but not much is known on how their interactions are modified by plant diversity and elevated atmospheric CO2 concentrations. Factorially manipulating grassland plant species diversity and atmospheric CO2 concentrations for five years, we tested whether high diversity or elevated CO2 sustain larger or more a...
