Using count data regression models, we find that trapping did not affect subsequent captures when we analyzed non-ant arthropods. A transect of 100 m length with ten equidistant pitfall traps was established in each area, and the traps were operated twice a month for 24 hours. We studied the effect of a yearlong epigeal pitfall trapping exercise with 22 fortnightly capture events in four differently disturbed areas at the Colombian Pacific coast. Yet, one of its main drawbacks, the possibility that repeated collecting may affect the study objects’ population, has not been formally tested.
Pitfall trapping remains one of the most frequently used methods to assess ground-active arthropods’ diversity and density. Corporación Colombiana de Investigación Agropecuaria - AgrosaviaĪrthropods population, Ectatomma ruidum, long-term trapping, pitfall trapping Abstract
