Urban Ecology of Ponds (Ottawa)

Interesting study by Christopher Hassall from the Department of Biology at Carleton University entitled:

Ottawa's ponds as an open-air laboratory for research into urban ecology

Here is the summary from the weblink:

This project investigated the biodiversity of urban water bodies used for storm water management in Ottawa, Canada. Preliminary findings suggest that some of these managed water bodies contain similar levels of biodiversity to unmanaged, "natural" water bodies, although there are a number of highly degraded managed sites with very low biodiversity. The presence of fish in 10 out of 20 managed ponds suggests relatively healthy ecosystems. Analysis of mosquito monitoring data suggests that the presence of managed water bodies does not affect the number of mosquitoes in an area. In conclusion, urban ponds can contribute ecosystem services including storm water management and biodiversity without increases in insect disease vectors.
