Population dynamics of American dog ticks (Acari: Ixodidae) along park trails 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...

Survival and band recovery rates of sympatric grey ducks and mallards in New Zealand 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. Survival rates of...

Extensive monitoring programmes viewed as long-term population studies: The case of North American waterfowl 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...

Estimates of movement and site fidelity using mark-resight data of wintering Canada geese 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...

Band reporting rates for mallards with reward bands of different dollar values 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...
