A TALE OF DRAGONFLY NATAL HABITAT PATTERNS IN A SERIES OF SMALL URBAN PONDS
Mount Auburn Cemetery (MAC) in Cambridge, Massachusetts is a quintessential green space in the heavily urbanizing landscape of metropolitan Boston. There are four separate, small wetlands within 71 ha MAC—differing in size (0.04 – 0.70 ha) and surrounding landscape matrix. I conducted cross-seasonal surveys of dragonfly exuviae at two of these ponds for five consecutive years; the other two ponds were included in the fourth and fifth years. Although the diversity of emerging species is low, even for urban ponds, there are some interesting patterns in the communities. For all five years the two original ponds (largest and smallest) supported entirely different species communities. In the fourth year (2019), new (different) species appeared at both. Surprisingly, one of the two new ponds also surveyed that year presented the highest species richness at the cemetery, including representative species from both the original ponds, and other species not found at either. This diversity pattern continued in the fifth year. I will discuss the potential role of surrounding upland habitat in influencing the emerging species patterns, and will compare these data with that from other urban pond studies.
