IBISCA-Panama 2003–2004


The aim of the project is to study the vertical stratification and beta diversity of arthropods in a rainforest in Panama, using the state-of-the art methods of canopy access and sampling, namely canopy fogging (pyrethrum knockdown), canopy crane, single rope techniques and canopy raft and peripherals. These different techniques complement each other for the entomological study of the rainforest canopy, and this project represents the first attempt to combine them in a large-scale study. These methods provided spatial replication during a field study of 6 weeks in 2003, whilst seasonal replication is being controlled for at the crane sites during the year 2004. Twenty three professional entomologists are seconded by many colleagues for the taxonomic study of the material. Each participating entomologist is responsible for a particular sampling protocol (15 different collecting methods in total) and studies 1-2 focal taxa (total in the order of 60 focal taxa studied).
