Optimal strategies for managing wildlife harvest under climate change
Wildlife populations are experiencing shifting dynamics due to climate and landscape change. Management policies that fail to account for non‐stationary dynamics may fail to achieve management objectives. We establish a framework for understanding optimal strategies for managing a theoretical harvested population under non‐stationarity. Building from harvest theory, we develop scenarios representi
Red Knot Migration and Population Ecology
Eastern Ecological Science Center biologists are studying migration and population ecology of the rufa red knot, a bird species that is dependent on horseshoe crab eggs to complete its trans-hemispheric migration. The birds' spring migration is timed with spawning of horseshoe crabs because the eggs are the perfect food for a migrating red knot.
Informing Management of Waterfowl Harvest in a Changing Climate
The ability to effectively manage wildlife in North America is founded in an understanding of how human actions and the environment influence wildlife populations. Current management practices are informed by population monitoring data from the past to determine key ecological relationships and make predictions about future population status. In most cases, including the regulation of waterfowl hu
Integrated population model for red knot in Delaware Bay
This is code for an integrated population model developed to understand the effect of horseshoe crab abundance on population demographics of red knot, an Arctic-breeding shorebird. This model was developed as part of the revision to the Atlantic States Marine Fisheries Commission Adaptive Resource Management Plan for horseshoe crabs.
Optimal horseshoe crab harvest policies via approximate dynamic programming
Approximate Dynamic Programming relies on forward simulation of the system, so two population projection models are used, one for crabs and one for red knots. The two models are linked: HSC abundance is a predictor variable in the REKN model. Other useful outputs are produced as well, such as predictions of future harvest.
