I'm delighted to announce that the first paper in a new multi-institution collaboration has been published this week in Global Change Biology. The paper brings together researchers who have been working on urban ponds for the past 20-30 years and who, between them, have accumulated a vast among of data. The result is that we can draw detailed inferences from the large dataset to evaluate the conservation value of ponds located within urban areas. The results show that urban ponds are no less diverse than non-urban (mostly agricultural ponds) and that urban ponds are more variable (which contradicts the usual pattern in urban habitats). You can read the paper here (and a pre-print is available here if you don't have access to the journal).
