Statistical sirens: The allure of nonparametrics Statistical sirens: The allure of nonparametrics

Although nonparametric statistical methods have a role to play in the analysis of data, often their virtues are overstated and their deficiencies overlooked. A recent Special Feature in Ecology advocated nonparametric methods because of an erroneously stated advantage that they require no assumptions regarding the distribution underlying the observations. The present paper points out...

Duck nest success in the prairie potholes Duck nest success in the prairie potholes

Since the early 1970's, the numbers of some waterfowl species such as mallard (Anas platyrhynchos), blue-winged teal (A. discors), and northern pintail (A. acuta) have reached or nearly reached the lowest ever recorded. Low nest success (the proportion of nests in which one or more eggs hatch) in key breeding areas, including the U.S. Prairie Pothole region, is partly responsible for...

Modified transmitter attachment method for adult ducks Modified transmitter attachment method for adult ducks

The value of radio telemetry for waterfowl research depends on the availability of suitable methods of attaching transmitters. In previous studies, external transmitters attached to adult Mallards (Anas platyrhynchos) with sutures and glue did not stay on birds reliably. In an attempt to improve transmitter retention, a method of attachment was tested in which 4-g transmitters were...

Tundra swan habitat preferences during migration in North Dakota Tundra swan habitat preferences during migration in North Dakota

I studied tundra swan (Cygnus columbianus columbianus) habitat preference in North Dakota during autumn migration, 1988-89. Many thousand tundra swans stop in the Prairie Pothole region during autumn migration, but swan resource use has not been quantified. I examined habitat preference in relation to an index of sago pondweed (Potamogeton pectinatus) presence, extent of open water, and...
