Selected Observatory Networks
Most at-risk species of freshwater turtle are long-lived, and in many instances individual turtles may outlive important habitat resources upon which they rely. For logistical reasons, most ecological studies last only a few years (although there are several incredible exceptions; see the work of Justin Congdon, Whit Gibbons, James Harding, Ron Brooks, and others). To understand the challenges to successfully conserving turtle populations in functional landscape contexts, it is helpful (and in some cases, necessary) to strategically undertake research on timescales relevant to the life history of the animal. In the case of most freshwater turtles in North America, this timescale is many decades.
We conduct long-term research focused on a range of vulnerable North American turtle species, and have launched, or proposed, a network of reference sites ("Observatories") in a variety of representative ecosystems. These long-term data sets will ultimately allow us to assess population status and trends, and more specifically to evaluate the effects of landscape and environmental change on populations of turtles. The Observatory model is rooted in five major principles:
1. Minimize negative effects of research
We strive to minimize disturbance to the population of turtles under study (see sections on Animal Use and Decontamination).
2. Prioritize studies in unfragmented, priority landscapes
Another emphasis of the Observatory model is long-term, sustained study of functional turtle populations in diverse and representative landscape context.
3. Ensure study site replication where feasible
Where possible, we establish site replicates within target landscapes.
4. Utilize standardized or complementary protocols and track effort.
The model hinges upon collaborative partnerships, coordinated effort, and centralized analysis.
5. Conduct iterative, individual-based, spatially-explicit analyses
Currently, the Observatory Network encompasses thirty sites in eastern North America in Maine, New Hampshire, Massachusetts, Florida, Yucatán, Campeche, and Quintana Roo. Learn more about the individual Observatory sites and networks by following the links in the page-top navigation menu.
