Mallard Brood Movements, Wetland Use, and Duckling Survival During and Following a Prairie Drought
We used radiotelemetry to study mallard (Anas platyrhynchos) brood movements, wetland use, and duckling survival during a major drought (1988–1992) and during the first 2 years of the subsequent wet period (1993–1994) at 4 51-km sites in prairie pothole landscapes in eastern North Dakota, USA. About two-thirds of 69 radiomarked mallard broods initiated moves from the nest to water before noon, ...
متن کاملA Bayesian Approach to Estimating Mallard Duckling Survival: Understanding the Relationships with Wetland Density and Hatch Date
Mallard (Anas platyrhynchos) duckling survival is an important, but not well understood, component of reproductive success for the species. To further investigate how mallard duckling survival is related to hatch date and wetland density, we analyze duckling counts for broods in southwestern Manitoba during the late 1980’s. Various models are explored to explain the patterns in the observed dat...
متن کاملKetones: metabolism's ugly duckling.
Ketones were first discovered in the urine of diabetic patients in the mid-19th century; for almost 50 years thereafter, they were thought to be abnormal and undesirable by-products of incomplete fat oxidation. In the early 20th century, however, they were recognized as normal circulating metabolites produced by liver and readily utilized by extrahepatic tissues. In the 1920s, a drastic "hyperk...
متن کاملThe Resurrecting Duckling - What Next?
In the context of the security of wireless ad hoc networks, we previously explored the problem of secure transient association between a master and a slave device in the absence of an online authentication server. We introduced the Resurrecting Duckling security policy model to address this problem. Master-slave relationships, however, do not exhaust the range of interesting interactions. We th...
متن کاملComparative phylogeography of two crow species: jungle crow Corvus macrorhynchos and carrion crow Corvus corone.
The jungle crow Corvus macrorhynchos Wagler, 1827, and the carrion crow Corvus corone L., 1758, are two closely related species with similar ecological requirements that occupy wide distribution ranges in the Palearctic. We studied patterns of their genetic variation by using sequences of the mitochondrial cytochrome b gene. Corvus macrorhynchos demonstrates a low level of variation and differe...
