Long-Term Decline in Body Size in a Snow Goose Population: Evidence of Environmental Degradation?
TLDR
Goslings reared by individual adult females showed a decline in size over time, suggesting that the general decline reflects a non-genetic change in gosling growth rates during the fledging period, and this reduction in food availability may reflect over-exploitation of primary food plants by the geese.

RETROSPECTIVE ANALYSIS OF DEMOGRAPHIC RESPONSES TO ENVIRONMENTAL CHANGE: A LESSER SNOW GOOSE EXAMPLE
In general, analysis of population dynamics can proceed either prospectively or retrospectively. In the case of the former, asymptotic expectations are generally derived (analytically or numerically)Expand
Body Size Variation in Lesser Snow Geese: Environmental Plasticity in Gosling Growth Rates
TLDR
Goslings that grew more slowly due to the effects of hatch date or brood size were significantly smaller as adults, which may have a significant effect on various life history traits in this species. Expand
Long-Term Changes in Survival Rates of Lesser Snow Geese
TLDR
The long-term changes indicate that mean values of age-specific survival rates are not adequate to describe the dynamics of this population of Snow Geese. Expand
The biologic effects of C225, a chimeric monoclonal antibody to the EGFR, on human prostate carcinoma.
TLDR
In vitro analysis of the EGFR from androgen-responsive and independent prostatic carcinoma cell lines revealed that C225 blocked EGF-induced receptor activation and induced internalization of the receptor, suggesting that C 225 may have utility for the treatment of human prostate carcinoma in a clinical setting.

The embarrassment of riches: agricultural food subsidies, high goose numbers, and loss of Arctic wetlands a continuing saga
Agriculture has provided a nutritional subsidy to the Anatidae (swans, geese, ducks), which has affected their trophic relationships and the Arctic wetlands where they breed. The Mid-ContinentExpand
The Snow Geese of La Perouse Bay: Natural Selection in the Wild
TLDR
A fitness components model of Snow Goose life cycle Pairing, mating, and parental care, and annual variation in fitness components are studied. Expand
Environmental change and the cost of philopatry: an example in the lesser snow goose
TLDR
The larger goslings in non-traditional feeding areas showed significantly higher firstyear survival, suggesting that the use of deteriorating traditional feeding areas may currently be maladaptive in this population. Expand
Transient population dynamics:relations to life history and initial population state
TLDR
Conservation and wildlife biologists should consider transient dynamics when developing management plans that could affect a population’s state, or whenever population state could be unstable, according to asymptotic measure of population growth rate. Expand
CHANGES IN SURVIVAL RATES OF LESSER SNOW GEESE WITH AGE AND BREEDING STATUS
TLDR
Although there was some evidence that older birds were slightly more vulnerable to hunters, there were no signs of any changes in survival rate with age in older geese, indicating that senescence, if it affects survival, does not do so for at least the first 10 to 15 years of age. Expand
