Recolonization patterns of meiobenthic communities in brackish vegetated and unvegetated habitats after induced hypoxia/anoxia

摘要: In a lagoon (Valle Smarlacca) of the ‘Valli di Comacchio’ complex (Northern Adriatic Sea, Italy) phytal habitat (Ruppia sp.) was chosen to investigate modifications and following recovery meiobenthic communities caused by induced hypoxic/anoxic disturbance. A field experiment carried out incubating, for three days, portions seagrass meadow adjacent unvegetated muddy sediment patches means dark benthic cham­bers. After these were removed, species both nematodes copepods showed different degree resistance On whole, on small scale present experiment, ap­pear highly resilient. As nematodes, recolonization patterns community differently influenced habitat. bare sediment, structure followed natural evolution control while, in Ruppia meadow, more according behaviour infaunal species, respectively. copepods, mainly driven dominant each control. other hand, heavier impact disturbance slow restoration its canopy seem delay rates copepod populations affect pattern.
