PDF position – Duck traveling waves across heterogeneous landscapes In collaboration with researchers at Ducks Unlimited Canada and University of Guelph, we are undertaking an assessment of broad-scale patterns of numerical change among breeding waterfowl populations in central North America. The project will involve analysis of data from 50+ years of surveys conducted on breeding duck numbers in the prairies, using what may constitute the most extensive animal population survey in the world. Specifically, we seek to understand patterns of change in abundance of 10+ duck species, including: 1- the relative contribution of endogenous (i.e., density-dependent) vs. exogenous (i.e., climate-related) factors influencing numerical variability; 2- the relationship between inter- specific synchrony and landscape and climate features; 3- whether recent reduction in patterns of population density dependence correspond to decoupling in spatial dynamics; and 4- the influence of habitat and climate on breeding distribution and numerical variability. We hypothesize that breeding duck population change conforms to a ‘traveling wave’ that is entrained by climatic or landscape variables, and that density-dependent mechanisms regulating the population have lessened through time. The proposed work builds on our recent analysis showing similar broad-scale patterns of duck population change (Murray et al. 2010, Ecology 91: 571- 581). The scope and extent of the duck survey dataset allows us to test the above fundamental ecological questions at a fine scale across an extensive landscape; few (if any) other animal population datasets would possess the requisite detail to conduct such work. The post-doctoral fellow will have the opportunity to develop an independent research program within the framework of existing funding.
