Table 1.
Relative abundances (± SD) of nematode taxa identified in the initial assemblage, the control one (C), and those exposed to hydroxychloroquine (HCQ1, HCQ2 and HCQ3). Sensitive and tolerant species to HCQ were marked with gray and back, respectively. Feeding groups according to Wieser Wieser (1953) (FG): selective deposit-feeders (1A); non-selective deposit-feeders (1B); epistrate-feeders (2A), omnivores-carnivores (2B). Species absent (−). Bold values indicate dominant species (≥ 10% according to Engelmann (1978)).
