Ground-water age and atmospheric tracers: Simulation studies and analysis of field data from the Mirror Lake site, New Hampshire Ground-water age and atmospheric tracers: Simulation studies and analysis of field data from the Mirror Lake site, New Hampshire
The use of environmental tracers in characterization of ground-water systems is investigated through mathematical modeling of ground-water age and atmospheric tracer transport, and by a field study at the Mirror Lake site, New Hampshire. Theory is presented for modeling ground-water age using the advective-dispersive transport equation. The transport equation includes a zero-order source...

Estimation of tiger densities in India using photographic captures and recaptures Estimation of tiger densities in India using photographic captures and recaptures
The tiger (Panthera tigris) is an endangered, large felid whose demographic status is poorly known across its distributional range in Asia. Previously applied methods for estimating tiger abundance, using total counts based on tracks, have proved unreliable. Lack of reliable data on tiger densities not only has constrained our ability to understand the ecological factors shaping...

Are adult nonbreeders prudent parents? The kittiwake model Are adult nonbreeders prudent parents? The kittiwake model
Understanding evolutionary consequences of intermittent breeding (nonbreeding in individuals that previously bred) requires investigation of the relationships between adult breeding state and two demographic parameters: survival probability and subsequent breeding probability. One major difficulty raised by comparing the demographic features of breeders and nonbreeders as estimated from...

New Jersey Tide Telemetry System New Jersey Tide Telemetry System
Each summer the population of the barrier-island communities of New Jersey increases by tens of thousands. When a hurricane threatens these communities, the few bridges and causeways that connect the islands with the mainland become overcrowded, making evacuations from the barrier islands to the mainland difficult. Timely evacuation depends on well defined emergency evacuation plans used...

Preliminary paleontologic report on core 37 from Pass Key, Everglades National Park, Florida Bay Preliminary paleontologic report on core 37 from Pass Key, Everglades National Park, Florida Bay
Sediments from Pass Key core 37, in eastern Florida Bay (N 25.1478, W 80.5745) record a history of rapid sedimentation during this century. The lowest portion of the core contains benthic fauna indicative of relatively low salinities and sparse seagrass coverage. This period is followed by an increase in salinity and seagrass. In the middle portion of the core, a slight decrease in...

Mortality and survival of white-tailed deer Odocoileus virginianus fawns on a north Atlantic coastal island Mortality and survival of white-tailed deer Odocoileus virginianus fawns on a north Atlantic coastal island
Mortality and survival of white-tailed deer Odocoileus virginianus fawns (N = 29) were studied from birth to one year of age during 1991–95 on Mount Desert Island (MDI), Maine, where deer hunting is prohibited, coyotes Canis latrans have become recently established, and protected U.S. National Park lands are interspersed with private property. The rate of predator-caused mortality was 0...

Somerset County Flood Information System Somerset County Flood Information System
Introduction The timely warning of a flood is crucial to the protection of lives and property. One has only to recall the flood of August 2, 1973, in Somerset County, New Jersey, in which six lives were lost and major property damage occurred, to realize how unexpected and costly, especially in terms of human life, a flood can be. Accurate forecasts and warnings cannot be made, however...
