Urbanization: Planting Forests in Pots

Urbanization in China drives soil acidification of Pinus massoniana forests

Soil acidification instead of alkalization has become a new environmental issue caused by urbanization. However, it remains unclear the characters and main contributors of this acidification. We investigated the effects of an urbanization gradient on soil acidity of Pinus massoniana forests in Pearl River Delta, South China. The soil pH of pine forests at 20-cm depth had significantly positive ...

Postural tachycardia syndrome (POTS).

INTRODUCTION POTS is defined as the development of orthostatic symptoms associated with a heart rate (HR) increment >or=30, usually to >or=120 bpm without orthostatic hypotension. Symptoms of orthostatic intolerance are those due to brain hypoperfusion and those due to sympathetic overaction. METHODS We provide a review of POTS based primarily on work from the Mayo Clinic. RESULTS Females p...

Pots :a Oo Lotos Approach

Urbanization Drives SOC Accumulation, Its Temperature Stability and Turnover in Forests, Northeastern China

Global urbanization is a vital process shaping terrestrial ecosystems but its effects on forest soil carbon (C) dynamics are still not well defined. To clarify the effects of urbanization on soil organic carbon (SOC) variation, 306 soil samples were collected and analyzed under two urban–rural gradients, defined according to human disturbance time and ring road development in Changchun, northea...
