Resumen

FERNANDEZ, Hugo R. Does wrong procedence assignment lead to underestimates in groundwater biodiversity?. Ecol. austral [online]. 2004, vol.14, n.1, pp.77-81. ISSN 1667-782X.

Individuals of certain taxa (e.g., water mites and crustaceans) collected from streams and rivers are often assigned to a surficial benthic origin when the animals clearly display subterranean morphological characteristics. This paper addresses reasons for these errors and proposes ways to minimize such mistakes when sampling.
