Wetland creation and restoration for biodiversity
many wetlands have been created and restored worldwide. Still, we lack large-scale wetland evaluations of the effects of wetland creation and restoration on biodiversity. In this thesis, I compared local and landscape effects to infer community responses to wetland creation. I then analysed species associations to find synergies and differences
Dissertations / Theses on the topic 'Wetland ecology'
This study assessed the effectiveness of a newly constructed 4.2 hectare wetland in Eastern Ontario as a sink for nutrients within an urban fringe watershed. During the initial two years after construction, the wetland was a sink for total phosphorus (TP) during the spring, summer and early fall.

Review Impact of climate change on wetland ecosystems: A critical
The impact of constructed wetland age on greenhouse gas emissions needs to be studied further as some research indicates that the developed wetlands can function as carbon sink with climate change (Whitting and Chanton 2001), whereas some other studies report a higher rate of carbon dioxide and methane with age as a result of more accumulation ...
