The relationship between annual survival rate and migration distance in mallards: An examination of the time-allocation hypothesis for the evolution of migration
Predictions of the time-allocation hypothesis were tested with several a posteriori analyses of banding data for the mallard (Anas platyrhynchos). The time-allocation hypothesis states that the critical difference between resident and migrant birds is their allocation of time to reproduction on the breeding grounds and survival on the nonbreeding grounds. Residents have higher reproduction and m

Survival of cackling Canada geese, 1982-1988
We estimated seasonal and annual survival rates of cackling Canada geese (Branta canadensis minima ) for the period 1982-1989 to identify periods of high mortality and assess effects of harvest management decisions. We tested hypotheses about age- and sex-specific variation in survival, seasonal variation in survival rates, and variation in survival between years in which hunting seasons were ope

Effect of hunting on annual survival of grey ducks in New Zealand
We used band recovery data from grey ducks (Anas superciliosa) banded in New Zealand between 1957 and 1974 to test 2 null hypotheses: (1) hunting mortality is completely additive to natural sources of mortality, and (2) hunting mortality is completely compensated by changes in natural mortality. We modeled annual survival as a function of survival in the absence of hunting and the probability of d

Estimates of movement and site fidelity using mark-resight data of wintering Canada geese
Population ecologists have devoted disproportionate attention to the estimation and study of birth and death rates and far less effort to rates of movement. Movement and fidelity to wintering areas have important ecological and evolutionary implications for avian populations. Previous inferences about movement among and fidelity to wintering areas have been restricted by limitations of data and me

Extensive monitoring programmes viewed as long-term population studies: The case of North American waterfowl
Several long-running and geographically extensive survey programmes provide information used to make annual management decisions for North American waterfowl populations. Data from these programmes can also be viewed as resulting from long-term population studies and have formed the basis for a number of retrospective analyses. Short-term studies have been used to investigate mechanisms underlying

Science, population ecology, and the management of the American black duck
This essay deals with the relevance of some of the ideas of Romesburg (1981) to population ecology and management of the American black duck (Anas rubripes). Most investigations dealing with the effects of hunting regulations on black duck populations have used the hypothetico-deductive (H-D) approach of specifying a priori hypotheses and associated deduced predictions. These investigations have

Population dynamics of American dog ticks (Acari: Ixodidae) along park trails
We conducted a mark–recapture study in which drag-collected ticks were removed from some park trails weekly from April to July. Weekly survival rates (probability of surviving and remaining on the trails) were significantly lower on trails used heavily by hikers, horses, and pets than on trails used less frequently. Although usage was the only obvious difference among these trails, differences in

Survival and band recovery rates of sympatric grey ducks and mallards in New Zealand
We used band recovery data from grey ducks (Anas superciliosa) and mallards. (A. platyrhynchos) banded sympatrically during 1957-74 to estimate annual survival and recovery rates. Young birds tended to have higher recovery rates and lower survival rates than adults for both species. Both species showed strong evidence of year-to-year variation in annual survival rates.

Band reporting rates for mallards with reward bands of different dollar values
Adult male mallards (Anas platyrhynchos ) were banded in summer 1987 with reward bands of different dollar values (0-$400) to determine the lowest dollar value that would yield a reporting rate approaching 1.0. During the 1987-88 and 1988-89 hunting seasons, rewards of between 50 and $100 were required to yield a reporting rate near 1.0. We estimated reporting rate of standard bands to be 0.32.

Survival rates of birds of tropical and temperate forests: Will the dogma survive?
Survival rates of tropical forest birds are widely assumed to be high relative to the survival rates of temperate forest birds. Much life-history theory is based on this assumption despite the lack of empirical data to support it. We provide the first detailed comparison of survival rates of tropical and temperate forest birds based on extensive data bases and modern capture-recapture models. We
