Parasitization of meadow voles, Microtus pennsylvanicus (ORD), by American dog ticks, Dermacentor variabilis (Say), and adult tick movement during high host density Parasitization of meadow voles, Microtus pennsylvanicus (ORD), by American dog ticks, Dermacentor variabilis (Say), and adult tick movement during high host density
The numbers of host-seeking adult American dog ticks, Dermacentor variabilis (Say), in a sweet gum field in Maryland reflected changes in the population density of a host species, the meadow vole, Microtus pennsylvanicus (Ord), which within 1.5 yr fell from an estimated 157 to 8 voles on a 0.8 ha grid. During high vole density, there was no significant difference (P > 0.05) in tick...

Physiological condition of autumn-banded mallards and its relationship to hunting vulnerability Physiological condition of autumn-banded mallards and its relationship to hunting vulnerability
An important topic of waterfowl ecology concerns the relationship between the physiological condition of ducks during the nonbreeding season and fitness, i.e., survival and future reproductive success. We investigated this subject using direct band recovery records of mallards (Anas platyrhynchos) banded in autumn (1 Oct-15 Dec) 1981-83 in the Mississippi Alluvial Valley (MAV) [USA]. A...

The relationship between body mass and survival of wintering canvasbacks The relationship between body mass and survival of wintering canvasbacks
Mass and recapture histories of 6,000 Canvasbacks (Aythya valisineria) banded in upper Chesapeake Bay were used to test two hypotheses: (1) early-winter body mass is associated with the probability of surviving the winter, and (2) early-winter body mass is associated with annual survival probability. Data were analyzed by a binary regression method that treated mass as a continuous...

Effects of liberalized harvest regulations on wood ducks in the Atlantic Flyway Effects of liberalized harvest regulations on wood ducks in the Atlantic Flyway
Beginning in 1977the FWS provided southern Atlantic Flyway states the opportunity to liberalize wood duck harvest regulations. Harvest subsequently increased throughout the flyway but appeared to be more a function of population growth than changes in regulations. In the South, harvest rate increased only slightly for young males and no decline in average survival was detected. We found...
