Resumen:
Approximately 80% of neotropical forests are subject to unsustainable economic practices,such as logging. Spiders are amegadiverse taxonomic group with a particularly great diversityin forest ecosystems and could help indicate the sustainability of logging operations. At sixsites at 400?700 m altitude in the piedmont forest of north-western Argentina, spiders collectedusing pitfall traps and forest structure and spider assemblage structure variables werequantified in order to examine the association between them and to identify indicator spiderfamilies. Logging changes forest structure and seems to generate an unsuitable habitat forspiders associated with mature forests. The family taxonomic level is a good surrogate forspider morphospecies. The Mysmenidae, Nemesiidae, Theridiidae, Pholcidae, Hahniidaeand Tetragnathidae families were associated with upper canopy cover of 20% or more andwith more than two dead fallen trees per 0.1 ha and >15 live trees per 0.1 ha, found inunlogged forests. Bearing in mind that the piedmont forest of north-western Argentina isbeing logged in the absence of sustainability criteria, we suggest including spiders in monitoringschemes to complement the information obtained from more readily used groups,such as charismatic vertebrates.
