Productivity and population increase of subarctic breeding canvasbacks

Article Abstract:

The canvasback population is failing to increase, despite restrictions on its harvest. Other factors that may constrain population growth could be reductions in habitat quality and size. A new study seeks to discover the productivity of canvasbacks breeding an an area of subarctic boreal forest in the Northwest Territories over a four year period. The study shows high rates of nest success, but below average clutch sizes.

Logic and science in wildlife biology

Article Abstract:

A common feature of wildlife science is the comparison and testing of biological and ecological hypotheses. While much has been written about hypothesis testing, it remains unclear how the link between theory, testable predictions and casual hypotheses can be recognized. The biological context for scientific methodology is discussed.
