ALAS Berlese Collections, 2001 Expeditions

Berlese samples were not precisely georeferenced. Sample sites were subjectively chosen, stratified by the desired microhabitats. All samples were taken within 100m of the refuge building. Samples were approximately 1.5l in volume. Samples were either "hand" samples or "ring" samples. For hand samples, substrate was gathered by hand. For ring samples, the sample was taken by quickly placing a 14.5 cm inside diameter, 10cm deep PVC ring on top of the leaf litter, driving it into the ground, dislodging it, and placing the material in a bag. Samples were all stored in cloth bags, packed into backpacks, hiked out of the site, transported to the lab at La Selva, and suspended in Berlese funnels. All samples were placed in Berlese funnels within 24 hours of being obtained from the field. Collapsible cloth funnels were used. The sample bed was a 35 x 35cm piece of 6.6mm mesh hardware cloth, overlain with several layers of cheesecloth. The soil sample was broken apart and spread out on the cheesecloth. An incandescent light bulb was placed 15-20cm above the sample bed and the bulb and the sample covered with a pyramidal aluminum-foil shield. The first 36 samples were left under a 25 watt bulb for two days, then under a 50 watt bulb for three days. All subsequent samples were left under a 50 watt bulb for five days. Arthropods were collected in a Whirlpac bag filled with 95% ethanol suspended from the bottom of the funnel.

Microhabitat codes for the samples, incorporated into the collection code (see below), are as follows:

AS: ring sample, leaf litter and mineral soil
AH: ring sample, deep leaf litter
AM: ring sample, rotten wood
BS: hand sample, leaf litter and mineral soil
BH: hand sample, leaf litter
BM: hand sample, rotten wood
BF: hand sample, fungi
BE: hand sample, epiphytes
BV: hand sample, various substrates

The data fields, in order, are:

Collection code: a unique code for a collection. The "11" indicates that it is from the 1070m site, the "B" indicates it is a Berlese sample, the following two letters are the microhabitat code (see above), and the final three-digit number is a serial number beginning with 001 for the first Berlese sample and ending with 120 for the last Berlese sample.

Collector: ALAS refers to the ALAS staff at the site (Danilo Brenes, Maylin Paniagua, Ronald Vargas).

Collection date: in format day-month-year.
