Stable-Nitrogen Isotope Enrichment in Avian Tissues Due to Fasting and Nutritional Stress: Implications for Isotopic Analyses of Diet
TL;DR: A mechanism of tissue 6'5N enrichment due to reduced nutrient intake is hypothesized and the implications of these results to ecosystem studies using stable-nitrogen isotope analysis are discussed.
Journal ArticleDOI
The dynamics of landscape change and snow geese in mid‐continent North America
TL;DR: The Mid-Continent Population of the lesser snow goose, which breeds in the eastern and central Canadian Arctic and sub-Arctic, and winters in the southern United States and northern Mexico has increased 5-7% annually from the late 1960s to the mid-1990s, largely because of increased survival in response to an agricultural food subsidy as discussed by the authors.
Journal ArticleDOI
Matriarchal population genetic structure in an avian species with female natal philopatry.
TL;DR: The contrast between results of banding returns and mtDNA distributions in the snow goose raises general issues regarding population structure: direct contemporary observations on dispersal and gene flow can convey a misleading impression of phylogeographic population structure.
Journal ArticleDOI
Harvest, survival, and abundance of midcontinent lesser snow geese relative to population reduction efforts

TL;DR: In this article, the authors assessed the effectiveness of an extensive and unprecedented wildlife reduction effort directed at a wide-ranging migratory population of geese, and concluded that the midcontinent population has continued to grow during the conservation order, although perhaps at a reduced rate.
