Coccidioidal Pneumonia, Phoenix, Arizona, USA, 2000–2004
Community-acquired pneumonia (CAP) often results in severe illness and death. In large, geographically defined areas where Coccidioides spp. are endemic, coccidioidomycosis is a recognized cause of CAP, but its frequency has not been studied extensively. To determine the frequency of patients with coccidioidomycosis, we conducted a prospective evaluation of 59 patients with CAP in the Phoenix, ...
متن کاملContribution of disturbance to increasing seasonal amplitude of atmospheric CO2
Recent increases in the seasonal amplitude of atmospheric carbon dioxide (CO2) at high latitudes suggest a widespread biospheric response to high-latitude warming. The seasonal amplitude of net ecosystem carbon exchange by northern Siberian ecosystems is shown to be greater in disturbed than undisturbed sites, due to increased summer influx and increased winter efflux. Increased disturbance cou...

متن کاملcrop models efficiency and performance under elevated atmospheric co2
abstract radiation, water and co2 are three major resources requirement for crops growth and development and within a wide range, increasing each of them would increase the biosphere productivity. higher usage of fossil fuels is increasing the atmospheric co2 and according to known crop physiological functions, such conditions should increase the crops production. however there is a possibility...
متن کاملEnvironmental consequences of rapid urbanization in warm, arid lands: case study of Phoenix, Arizona (USA)
The Phoenix metropolitan area (Arizona, USA) provides an excellent case study for examining the sustainability of a rapidly growing urban ecosystem in an arid region, having grown six-fold in population in 50 years (to 3 million in 2000). The example is important, because the world’s urban population will nearly double in 30 years, and most of this growth will occur in warm, arid regions. Urban...
