Recovery of zooplankton diversity in a restored Mediterranean temporary marsh in Doñana National Park (SW Spain)

摘要: Over 30 years after drainage for agriculture, a 2700 ha temporary marshland was recently restored in Donana National Park. We describe the recovery of zooplankton communities (copepods, cladocerans and rotifers) 47 new ponds excavated as part restoration project during first two hydroperiods (April 2006 2007), compare them to those eight reference sites surrounding marshland. Major changes species composition abundance occurred between years. While rotifers cyclopoid copepods dominated terms number individuals 2006, calanoid were most abundant groups 2007. Rotifer richness significantly lower 2007, but there an increase Simpson β-diversity 2007 owing largely dramatic decline Hexarthra cf. fennica (rare sites) from 93% all rotifer only 32% In contrast, higher no diversity. β-Diversity also cladocera than sites, by differences or Overall, 7 copepod, 13 cladoceran 26 taxa recorded ponds, including 80% sites. These results indicate that can be rapidly Mediterranean wetlands, at least when large source populations area reduce dispersal limitation. They illustrate importance comparing different metrics diversity studies restoration.
