2006, Wildlife Society Bulletin (34) 1231-1237
Two of the most significant management efforts affecting waterfowl populations in North America are the North American Waterfowl Management Plan (the Plan) and Federal harvest management programs. Both the Plan and harvest management are continental in scope, involve an extensive group of stakeholders, and rely on adaptive processes of...
Estimating site occupancy and detection probability parameters for meso- and large mammals in a coastal eosystem
Allan F. O’Connell, Neil W. Talancy, Larissa L. Bailey, John R. Sauer, Robert Cook, Andrew T. Gilbert
2006, Journal of Wildlife Management (70) 1625-1633
Large-scale, multispecies monitoring programs are widely used to assess changes in wildlife populations but they often assume constant detectability when documenting species occurrence. This assumption is rarely met in practice because animal populations vary across time and space. As a result, detectability of a species can be influenced by a...

Donald R. Cahoon
2006, Estuaries and Coasts (29) 889-898
Storms have long been recognized as agents of geomorphic change to coastal wetlands. A review of recent data on soil elevation dynamics before and after storms revealed that storms affected wetland elevations by storm surge, high winds, and freshwater flushing of the estuary (inferred). The data also indicate...
Comment on 'Are survival rates for northern spotted owls biased?'
A.B. Franklin, J.D. Nichols, R.G. Anthony, K.P. Burnham, Gary C. White, E.D. Forsman, David R. Anderson
2006, Canadian Journal of Zoology (84) 1375-1379
Loehle et al. recently estimated survival rates from radio-telemetered northern spotted owls (Strix occidentalis caurina (Merriam, 1898)) and suggested that survival rates estimated for this species from capture-recapture studies were negatively biased, which subsequently resulted in the negatively biased estimates of rates of population change (lambda) reported by Anthony et...
