Overall sampling protocol The aims are to carry out the 9 sampling programs (along with individual programs) at (as far as possible) each of the 9 study sites (3C, 3R, 2B, 1I). The sampling procedure should be identical or similar at each study site, to allow statistical comparison of the results between the sites. The main sampling programs are (c = targets canopy, s = targets soil): Vegetation Light trapping (c) Sticky traps (c) Soil/Canopy microarthropods (s, c) Flight interception traps (c) Winkler - litter (s) Beating (c) Pitfall traps (s) Fogging (c) Individual programs (s, c)
Sampling program: Vegetation Managers: S.J. Wright, F. Hallé, S. Ribeiro, M. Samaniego & Andres Hernandez Aims: compare the vegetation (species richness, frequency) in the understorey and upper canopy of 12 sites (9 + 3 surrogate crane sites) Technique: a 20m x 20m plot is grided on the ground. The vegetation up to 2m is measured and mapped using standard techniques. Similarly a 400m2 plot is surveyed in the upper canopy, and the vegetation recorded within the last meter. Methods: 100 random points (or within reach) in where encounters between leaves and a PVC stick are recorded. Measurement of canopy height by range finder. Notes: 1. Bubble. Upper canopy = transect line; understorey = both 20 x 20m plot plus transect line 2. Ikos. Upper canopy = simplified survey; understorey = 20 x 20m plot 3. Vertical point-transects may also be organised by S. Ribeiro at all sites 9 sites (3C, 3R, 2B, 1I) to survey in the understorey and canopy 3 sites (3C’) to survey in the understorey only (no canopy access) Thus 9+9+3 = 21 ‘plots’ (canopy+understorey) Schedule for one site: 1 field day for establishing ground plot and marking large trees/shrubs 1 field day for canopy plot 1 field day for further work at the ground plot
25m Sampling program: Sticky traps Managers: Y. Basset, G. Curletti & R. Harrison Aims: compare the flying activity of small insects in the understorey and upper canopy Technique: yellow sticky traps, set up either in the understorey (n = 25, at 1.3m, DBH) and upper canopy (n = 25) at each site. In addition, if possible, 3 vertical transects of 8 traps (0m, 1.3m (DBH), 7m, 14m, 21m, 28m, 35m and 42m [top]) will be set up at each site. Correlation with crown openness and incident light may be possible. The traps will be running for 5 days at each site. Position of traps on the raft; in crane subplots, traps are similarly set up in the periphery. Total 74 samples (traps) per site, 25 upper canopy + 25 understorey + 3 x 8 traps in transects Ikos: only one transect of 8 traps 9 sites (3C, 3R, 2B, 1I): Total (8 x 74) + 8 = 600 samples Position of sticky traps at 1.3m (DBH) at crane and raft sites (20mx20m): mostly inside the plot Schedule for one site: 1 field day for set up of traps 3 days laboratory BCI/University Panama 1 field day survey traps + measurement variables 9 sites x 5 = 45 days (out of 40) Overlap for Ikos site and one crane site, so that 7 x 5 = 35 days Position of traps in one bubble transect; 1 sample each meter; understorey samples are vertical to canopy samples Material needed: 600 traps, benzina, luxmeters, 3-6 weighted line transects, etc.
Sticky traps: transects Aims: compare the flying activity of small insects at selected transects (3 per site) and height: 0m, 1.3m, 7m, 14m, 21m, 28m, 35m and 42m (top). Climbing rope: not established at random (security) Transect line lowered with sand weight, close to the climbing rope, and secured up and down. This line includes pre-measured distance and attachment points for the traps. Traps are set up when one person climbs and activated when abseiling down. Simultaneous recording of incident light at all transect levels (2 luxmeters) Survey: Before surveying each trap, incident light is measured and two fisheye pictures of the canopy above the trap are shot. Simultaneously the incident light at the brightest point in the upper canopy is recorded. Similar measurements are performed at the 25 traps in the upper canopy and 25 traps in the understorey. These measurements will be used for the sticky trap program, but also to characterize overall the site Crown openness determined at all levels by hemispherical pictures
Sampling program: Flight interception traps Managers: R. Didham & L. Fagan Aims: compare the flying activity of insects in the understorey and upper canopy Technique: FITs set up in transects of 8 traps each. 24 traps at each sites, working for two weeks. Crane sites first, bubble, icos and (possibly) raft sites later on. Care is needed about emplacement of FITs (use sticky trap transects whenever possible) and possible interaction with fogging. 3 transects per site Total 8 x 3 = 24 samples (traps) per site 9 sites (3C, 3R, 2B, 1I): Total 9 x 24 = 216 samples Position of transect below the raft or crane subplots Schedule for one site: 1 field day for set up of traps 2 days laboratory BCI/University Panama 1 field day survey traps 9 sites x 4 = 36 days (out of 40) Position of transects in one bubble site As far as possible, FITs will be set up on the same transects than sticky trap transects, but after sticky traps are surveyed

Ødegaard Aims: compare the foliicolous fauna in the understorey and upper canopy Technique: quantitative beating (1 sample = 0.85m2 beating sheet full of foliage = 1 bag) During day-time (night work is to be considered). Identical beating sheet should be employed.

Sampling programs: Individual programs Social insects: A. Dejean, B. Corbara, J. Orivel, A. Floren, M. Leponce & Y. Roisin Pollinators: D. Roubik & D. Frame CO2 and soil respiration: C. Potvin & students Ground FITs: A. Tishechkin & G. Curletti Wood borers: F. Ødegaard & G. Curletti Gall-makers: S. Ribeiro Note: at crane sites, individual programs need to be performed outside the crane perimeter AND outside the botanical plot. That is near the sites C1’, C2’ and C3’.
Summary: ground plots Most samples will concentrate on the 20x20m ground plot, but not all, as this would bias samples. The inner area of 20m x 20m (see diagram next page) will be restricted to a few sampling programs. More destructive programs, including individuals programs would need to be performed at some distance of the plot. This is indicative only, as some programs need to overlap between sites (sticky traps). Sequence of sampling: Day 1: Griding and vegetation survey; beating Day 2: Set up of sticky traps, pitfall traps Day 3: Light trapping; microarthropods Day 4: Individual programs Day 5: Survey of pitfall traps; Winkler transects Day 6: Individual programs Day 7: Survey of sticky traps Day 8: Fogging (not close to FITs, may be scheduled later); set up of FITs on sticky trap transects Later: survey of FITs (two weeks later); refine vegetation survey if needed And at all time: work on individual programs outside the plot permitted
Microarthropods (n = 3 trees) situation variable, maybe outside the plot Ground plots: summary Transects Sticky and FIT traps ONLY vegetation, sticky traps, light traps & microarthropods 1 20m Beating: extends 5-10m beyond plot 2 All individual programs: extends 50-100m beyond the plot 3 20m Pitfall traps (n=15), each 1.3m Winkler transects Light traps (n = 3) Walking and access area (for raft sites) Sticky traps at 1.3m (n=25), may extend beyond the plot PVC marks for vegetation study Fogging: preferably in area 3 Not to scale
Summary: canopy plots Most samples will concentrate on the 20x20m canopy plot, but not all, as this would bias samples (see diagram next page). This is indicative only, as some programs need to overlap between sites (sticky traps). Sequence of sampling: Day 1: Vegetation survey; beating Day 2: Set up of sticky traps Day 3: Light trapping; microarthropods Day 4: Vegetation/individual programmes Day 5: Vegetation/individual programmes Day 6: Vegetation/individual programmes Day 7: Survey of sticky traps Day 8: Fogging (not close to FITs, may be scheduled later); set up of FITs Later: survey of FITs (two weeks later) And at all time: work on individual programs below the sites or adjacent to them The Icos site will be more limited
Canopy plots: summary (Example of one raft site) Light traps Sticky traps: 25 traps on the periphery and 3 vertical transects Beating samples: 20 samples on the periphery Microarthropods: 3 trees below/adjacent to the raft Sticky and FIT traps transects Individual programmes: on the raft or adjacent Fogging: preferably adjacent to vertical projection of the raft
