Tracking the spring migration of a bar-headed goose (Anser indicus) across the Himalaya with satellite telemetry Tracking the spring migration of a bar-headed goose (Anser indicus) across the Himalaya with satellite telemetry
Soil-food-chain-pesticide wildlife relationships were investigated to learn the concentration of pesticide residues present in soils, macro-invertebrates, vertebrates, and seeds as a result of annual applications of aldrin at recommended rates for pest control. Two central Missouri cornfields treated witb aldrin at 1 lb/acre, for 16 and 15 of the past 17 years, were selected for study...

Variability of bed mobility in natural, gravel‐bed channels and adjustments to sediment load at local and reach scales Variability of bed mobility in natural, gravel‐bed channels and adjustments to sediment load at local and reach scales
Local variations in boundary shear stress acting on bed‐surface particles control patterns of bed load transport and channel evolution during varying stream discharges. At the reach scale a channel adjusts to imposed water and sediment supply through mutual interactions among channel form, local grain size, and local flow dynamics that govern bed mobility. In order to explore these...

The use of fuel breaks in landscape fire management The use of fuel breaks in landscape fire management
Shaded fuelbreaks and larger landscape fuel treatments, such as prescribed fire, are receiving renewed interest as forest protection strategies in the western United States. The effectiveness of fuelbreaks remains a subject of debate because of differing fuelbreak objectives, prescriptions for creation and maintenance, and their placement in landscapes with differing fire regimes. A well...

Tidal influence on spatial dynamics of leopard sharks, Triakis semifasciata, in Tomales Bay, California Tidal influence on spatial dynamics of leopard sharks, Triakis semifasciata, in Tomales Bay, California
We used ultrasonic telemetry to determine the movement directions and movement rates of leopard sharks, Triakis semifasciata, in Tomales Bay, California. To analyze tide and time of day effects, we surgically implanted transmitters in the peritoneal cavities of one male and five female leopard sharks, which we located during summer for three to five sampling sessions lasting 12 to 24 h...

Root growth and function of three Mojave Desert grasses in response to elevated atmospheric CO2 concentration Root growth and function of three Mojave Desert grasses in response to elevated atmospheric CO2 concentration
Root growth and physiological responses to elevated CO2 were investigated for three important Mojave Desert grasses: the C3 perennial Achnatherum hymenoides, the C4 perennial Pleuraphis rigida and the C3 annual Bromus madritensis ssp. rubens. Seeds of each species were grown at ambient (360 μl l−1) or elevated (1000 μl l−1) CO2 in a glasshouse and harvested at three phenological stages...
