Tree Transplanting and Establishment

Many aspects of transplanting change over time. Modern equipment has made it possible to transplant larger trees with "soil balls" more affordably. Containerized production has grown in popularity for many reasons, including the ability to plant in any season. One thing remains the same-plants must quickly establish or reestablish a normal, spreading root system on the new site to minimize susc...

Calcium Availability Limits Reproductive Output of Tree Swallows (tachycineta Bicolor) in a Nonacidified Landscape

as calcium. The extent to which calcium limits reproduction in wild birds is unclear. We performed a supplementation experiment to determine whether calcium limits the reproductive output of free-ranging insectivorous Tree Swallows (Tachycineta bicolor), a species whose usual diet contains li' le calcium. Providing supplemental calcium in the form of crushed oyster shell did not aff ect clutch ...

Extreme Availability: Determining the Limits of Availability in Commercial Systems

High availability has become increasingly important to businesses with the advent of the Web and various associated e-commerce services. This paper describes the key attributes of the very highest availability systems. Such systems and their associated support environments are qualitatively different than other systems, even other high availability systems; for the purposes of this paper these ...

Estimating Moisture Content of Tree-length Roundwood

The green weight of southern pine tree-length roundwood delivered to the pulp mill is generally known. However, for optimum mill efficiency it is desirable to know dry weight. The moisture content of tree-length pine logs is quite variable. The moisture content of pine tree-length logs increases significantly with increasing stem height. Moisture content also varies with tree age and geographic...
