Drought-related tree mortality occurs globally and may increase in the future, but we lack sufficient mechanistic understanding to accurately predict it. Here we present the first field assessment of the physiological mechanisms leading to mortality in an ecosystem-scale rainfall manipulation of a piñon-juniper (Pinus edulis-Juniperus monosperma) woodland. We measured transpiration (E) and mode...

For nearly two decades, the American Southwest has been in grips of a long-term ‘megadrought’, punctuated by number short and severe ‘global change type droughts’ (i.e., negative precipitation anomalies co-occurring with high temperature). These events have caused widespread mortality drought-sensitive piñon pine (Pinus edulis) while co-dominant Juniperus spp. historically much more drought tol...

Our conclusion that a Juniperus virginiana stand in the central Appalachian Mountains is recovering from decades of acid deposition was based on tree ring carbon isotope ratios (δC) that show: (i) close correspondence between the timing of changes in direction of δC with declines in SO2 emissions occurring after the Clean Air Act; (ii) close similarities between patterns of δC after 1980 and du...

Background and purpose: Urolithiasis is one of the most common diseases of urinary tract. Abdominal colic pain, nausea and vomiting, and hematuria are the major clinical complains. Renal stones may obstruct urinary tract, and then damage the kidney. Medical treatment, removing the stones by extracorporeal shock wave lithotripsy, percutaneous lithotripsy, and ureteroscopic lithotripsy are common...

In this study, we analyzed distribution of species the genus Gymnosporangium in mountain regions Uzbekistan, including Western Tien Shan and Pamir-Alay. Four (G. confusum, G. sabinae, fusisporum, turkestanicum) are reported for Uzbekistan. The telial hosts these rust fungi Juniperus, while aecial Uzbekistan representatives genera Cotoneaster, Crataegus, Sorbus, Pyrus (all Rosaceae). It has been...
