We present and compare demographic data for cerulean warblers (Dendroica cerulea) from 5 study sites across the range of the species from 1992 to 2006. We conducted field studies to collect data on daily nest survival, nest success, and young fledged per successful nest, and we used data to estimate fecundity. Daily nest survival, nest success, young fledged, and fecundity varied widely across the cerulean range and among years. Study sites in agriculture-dominated landscapes (Mississippi Alluvial Valley, IN, and MI, USA) had negative growth rates in all years monitored because measured values of nest success and young produced per successful nest were incapable of offsetting apparent mortality. Ontario (Canada) and Tennessee (USA) populations had greater nest success and fecundity but still appeared to be incapable of producing stable populations (λ = 1) under field-measured and assumed conditions. We had survival data only for one site (Ontario); thus, additional survival data are greatly neede...

Wind has become one of the fastest growing sources of renewable energy worldwide, but widespread and often extensive fatalities of bats have increased concern regarding the impacts of wind energy development on bats and other wildlife. We synthesized available information on patterns of bat fatalities from a review of 21 postconstruction fatality studies conducted at 19 facilities in 5 United States regions and one Canadian province. Dominance of migratory, foliage- and tree-roosting lasiurine species (e.g., hoary bat [Lasiurus cinereus]) killed by turbines was consistent among studies. Bat fatalities, although highly variable and periodic, consistently peaked in late summer and fall, coinciding with migration of lasiurines and other species. A notable exception was documented fatalities of pregnant female Brazilian free-tailed bats (Tadarida brasiliensis) in May and June at a facility in Oklahoma, USA, and female silver-haired bats (Lasionycteris noctivagans) during spring in Tennessee, USA, and...

In early 2002, the Tennessee Valley Authority (TVA) completed a revision of its Environmental Management System (EMS). The new EMS is designed to fully align with the International Organization for Standardization (ISO) 14001 EMS standards. The EMS incorporated a new Environmental Review Process as an integral component. It established clear roles and responsibilities for the agency NEPA (National Environmental Policy Act) staff and organizations across TVA, introduced process improvements and standardization measures, and made structural changes to bring about increased efficiency and effectiveness in NEPA reviews. The NEPA process was further strengthened by its integration into the revised comprehensive EMS. A new Environmental Policy and Principles was adopted that reestablished the TVA commitments to environmental protection and stewardship, to assess and minimize the effects of TVA operations on the environment, and to involve the public. An Achievement Plan was developed to assure that TVA meets its corporate environmental commitment; that plan recognized the EMS as the principal tool for achieving that goal. Corporate environmental objectives and targets were established, and new methods to measure the overall environmental performance of TVA were introduced. Significantly, the NEPA process was directly linked to other EMS processes, including those for environmental training, communication and stakeholder involvement, records management, environmental auditing, corrective and preventive action, performance monitoring and reporting, and management review. These systematic linkages work together to reinforce all aspects of NEPA performance and to provide improved environmental compliance, cost savings in environmental management programs, and measurable improvements in achievement of TVA environmental objectives. The TVA experience, which takes an agency-wide rather than a facility-based approach to EMS development, may offer insights and an alternative strategy to other agencies addressing NEPA/EMS implementation issues.

To the Editor. —Being an active and interested surgeon in a community hospital, I find Dr Lee Sataline's ( Arch Surg 114:347, 1979) categorical remarks about surgeons focusing only on surgical problems and neglecting the preoperative and postoperative care of their patients to be disturbing. In my experience, I have had the responsibility for all preoperative and postoperative care. It is very seldom that I see a patient in consultation who requires any less. In our situation, the medically oriented doctors are continually wanting to transfer their sick patients to the care of a surgeon. Even the most innocuous procedures are referred to the surgeon. These are procedures such as bone marrow aspirations, sigmoidoscopic examinations, and insertion of subclavian catheters. It is my opinion that the modern-day surgeon is well versed and eager in total patient care and is not seeking an easy life.
