Long- and Mid-Term Trends in the Waterbird Community: Functional and Ecological Turnovers After Restoration of Freshwater and Brackish Habitats in a Mediterranean Coastal Wetland

In the Mediterranean, urban and agricultural development has led to degradation of coastal habitats a decline in wetland biodiversity. L’Albufera de Valencia is paradigmatic case-study, with intensive rice fields, scarcity natural aquatic habitats, an unfavorable conservation status. Since 1990s, restoration efforts have been made freshwater brackish environments. this study, long-, medium-, short-term dynamics ecological functional traits were analyzed for waterbird communities. We found that these areas had facilitated establishment resilient communities higher specialization diversity than rest protected area, including threatened species. Overall, improved population compared surrounding hyper-eutrophic lagoon fields. The findings reveal two complementary paradoxes linked succession. Initial affected small, pioneer species high value, while larger concern displaced them over time. Dynamics influenced by body mass, less competition Notably, large waders vegetation gleaners nesting restored wetlands exhibited greater sensitivity succession, reversing regional declines. These highlight importance increasing various stages succession meet needs

Regulating Denitrification in Constructed Wetlands: The Synergistic Role of Radial Oxygen Loss and Root Exudates

Water, Journal Year: 2024, Volume and Issue: 16(24), P. 3706 - 3706

Constructed wetland (CW) is a critical ecological engineering for wastewater treatment and improvement of water quality. Nitrogen (N) removal one the vital functions CWs during operation, N in mainly affected by aquatic plants denitrification carried out microbes. However, due to their low efficiency instability removal, further applications are limited. The review provides view two basic characteristics plants, radial oxygen loss (ROL) root exudates, coupled effect on processes CWs. First, role presented. individual roles ROL exudates regulating denitrification, as well interaction this process, have been discussed. Also, limitation conventional techniques reveal between plant microbes has highlighted. Further research coupling regulatory mechanisms may be conducted develop an optimal design improve biological removal. This offers new insights directions improving utilizing synergistic effects exudates.
