“…Also in the 1-1.5 cm layer of normoxia the abundances were significantly higher with RB. The presence of lower numbers of live -CTG-labelled -nematodes in top normoxic layer might reflect the short generation time of some species, namely days to weeks (Platt et al, 1985;Martinez et al, 2012). Even though the decomposition is relatively fast (Kammenga et al, 1996), nematodes do not disintegrate within hours/days; therefore the density of living nematodes may be overestimated in ecological/monitoring studies based solely on RB staining.…”

“…Different responses among genera in the same trophic group are common (Porazinska et al, 1999), and nematode genera within the same trophic group can exhibit asymmetric competition, negatively influencing the abundance of other genera (Postma-Blaauw et al, 2005). Such interaction outcome may be due to the limited similar food source, which resulted to competition and resource depletion, and in turn increased the competition between species (Martinez et al, 2012). Eventually, uninterrupted competition may lead to inhibition where individuals of one species suffer a reduction in growth, survivorship and fecundity as a consequence of resource exploitation or interference of the other species (Begon et al, 1996;Keddy, 2001).…”

“…Sublethal Cd concentrations used in the study were 1.4 mg L -1 and 1.9 mg L -1 . Sublethal concentrations were determined based on the LC 50 of Cd on both A. nanus and P. parvus (Martinez et al, 2012). Using a fine copper wire, five A. nanus and five B. monhystera adults were selected and placed in the partitioned Petri dish (monoculture set-up), and a combination of the nematode species (5 A. nanus : 5 B. monhystera) was placed in full Petri dish (interaction set-up).…”
