Investigating the BIodiversity of Soil and Canopy Arthropods Investigaciones sobre la Biodiversidad de los Insectos de la Selva Centro-Americana Inventaire de la Biodiversité des Insectes du Sol et de la Canopée Main sponsors: Solvin-Bretzel & Smithsonian Tropical Research Institute Scientific coordination: Smithsonian Tropical Research Institute (STRI) & Canopy Raft Consortium (CRC) First phase: 22 September to 31 October 2003 San Lorenzo Forest, Panama
This presentation concerns the main period of field work in Panama in 2003. It is only indicative, aimed at participants, and cannot be viewed as a comprehensive user manual of the different canopy access facilities that will be in operation during the project. The aim is to familiarize the participants with the logistics of the project and to pre-empty potential problems as much as possible. Prepared by Y.

Team spirit and work The IBISCA project will be both exciting and challenging, particularly in the field. We all have different research interests, but team work and spirit for this project are essential if we want to succeed. Please keep this in mind and enjoy your canopy experience in Panama.

IBISCA - Aims and Outline We propose 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, namely canopy fogging, canopy cranes, and canopy raft and peripherals. The canopy raft and fogging sites will provide spatial replication during a field study of 5 weeks, whilst seasonal replication will be controlled for at the crane site, during a one year period. We will study the arthropod fauna of 9 sites within the San Lorenzo Protected Area with an international team of 30 entomologists, seconded by many colleagues for the taxonomic study of the material. Each participating entomologist will be responsible for a particular sampling protocol (9 different collecting methods in total) and will study 1-2 focal taxa (total 40 focal taxa studied).
Study sites All sites will be located in the San Lorenzo Protected Area (near Colon, Caribbean coast, 9º17’N, 79º58’W; alt. 130 m). This tropical wet evergreen forest averages 3152 mm of annual rainfall and an annual air temperature of 25.8ºC. Three sub-sites will be within the perimeter of the San Lorenzo Canopy Crane and will allow for seasonal replication. The Canopy Raft, a 400m 2 platform of plastic beams and netting, will be set up with minimal damage on the canopy at 3 sites. In addition, the Canopy Bubble will run along a 1km transect, yielding access to 2 further sites. Last, one Ikos (icosaedron, ‘tree house’) will represents the ninth study site. Canopy fogging will be performed at all these sites (at 3 surrogate sites for the crane sites). All study sites will be located within a 2-3km radius of the crane site.
Canopy Raft (400 m 2 ): 3 sites elsewhere R1 I1 Positions and distances not exact and not to scale Total 9 sites: 3C, 3R, 2B, 1I, all within 2-3 km of the crane site B1 B2 Ikos (more or less 400 m 2 ): 1 site, not suitable for all programs Canopy Bubble: one transect of 1km, with two sites of 400 m 2 Crane perimeter (0.85ha) in which 3 sub-sites of 400 m 2 each will be delineated 3 ‘crane sites’ (400 m 2 ), close to the botanical plot, in which fogging and Winkler programs will be performed Crane botanical plot (6ha): no destructive studies allowed within 240m 54m 400m SITES R3R2 C1C2C3 C2’ C3’ C1’ 20m Buffer zone: 200m Activities within C1, C2 and C3 should be 3m away from 20 seedling stations managed by S.J. Wright
Logistics Most of participants will be based on Barro Colorado Island (BCI). Daily boat and 4WD vehicles will assure transportation from BCI to the study sites. Other participants will be based in Panama City, working at STRI and the University of Panama. The main laboratories and headquarters of the project will be based at BCI. Basic accommodation for night work will be provided at the crane site. Participants will switch activities from field work to laboratory work (half of the time each) during a five week period. Seven technical staff from CRC, including 3 professional tree climbers, will Assist the project. The tree climbers will help mainly with the 9 core sampling programs (see below).

Canopy Access -San Lorenzo Crane Managers: S.J. Wright, M. Samaniego & Y. Basset Timetable: 08h00 to 14h00; night work needs to be scheduled through M. Samaniego or Y. Basset Access: see guidelines next page Restrictions: No destructive sampling allowed (Winkler and fogging programs); lower canopy may need to be accessed through single rope techniques.
Steps to work with the San Lorenzo Crane 1. 08h00. Crane operator gives you a radio (channel ‘Smithsonian - Grua’) and climbs in the cabin. He then lowers the cable and crane hook. 2. You engage the crane hook into the large gondola ring. Operator lifts off slightly the hook so that you can insert the security cables on both small safety rings of the gondola. 3. You climb onboard the gondola and tell the operator with the radio that you are ready. He lifts up the gondola and you close the door. 4. You proceed, giving directions to the operator (see basic terms next page) 5. 14h00. You go down and follow the procedures in reverse order: open the door before touching ground, help the operator to land the gondola into the 4 ground holes, disengage security cables and unhook the gondola.
Crane - basic terms Up = arriba Down = abajo Right = derecha (for the operator) Left = izquierda (for the operator) Forwards = adelante, al frente Backwards = atrás Stop = alto More = más Less - menos To the ground = a tierra Thanks = gracias Hook Ring Gondola Safety ring Safety cable
