IBISCA (Investigating the Biodiversity of Soil and Canopy Arthropods) is an international research programme which aims at studying the spatial (horizontal, vertical, altitudinal) and temporal distribution of the organisms which constitute a major part of forest biodiversity: arthropods. Interactions with plants and selected other organisms are also studied.Our approach is based on highly integrative research projects and the use of state-of-the art canopy access techniques. Field projects are conducted worldwide in tropical, subtropical and temperate forests.Supporting institutions are Universities, Museums, networks and other research groups. Our sponsors are both public and private partners. In parallel to our scientific publications and meetings, we are also engaged in public outreach activities in order to improve public awareness of biodiversity studies.
