The Cave Swallow in Texas

Among the group of birds of tropical and subtropical distribution that reach their northern limits in the southwestern United States, the Cave Swallow (Petrochelidon fulvu) is of special interest since it nests colonially in caves. It was first reported in the United States by Scott (1890), who collected two vagrants of the.Cuban and Isle of Pines race, P. f. “caticoZa” (= cmmata, fide Hellmayr...

The landowner's alternative rate of return (ARR), stumpage prices, labor costs, and management practices also have an effect on profitability. To determine the best manageme...

Optimal management strategies for patients with complex congenital heart disease.

The combination of critical pulmonary outflow obstruction with a large ventricular septal defect is symbolized by the diagnosis of tetralogy of Fallot, the most common form of cyanotic congenital heart disease. In many ways, the history of management for patients with tetralogy is representative of the evolution of management for all children with complex congenital cardiac diagnoses. Tetralogy...

Management of Prairie Dog Populations in Wind Cave National Park

—Since the late 1920's there have been periodic control programs on black-tailed prairie dogs in Wind Cave National Park. The most recent control effort, which began in 1982, resulted in the reduction of total dogtown acreage from 2,000 to 750 acres. Recent studies carried out within the park have provided managers with more soundly based justification for carrying out control programs. The sam...
