Asian tropical forests are under extreme stress from clearance, fragmentation, and logging. Because Singapore suffered these same impacts in the 19 century, it can act as an early warning system for the region. We identified invasive exotic tree species from a comprehensive survey, assessed their survival and growth in the open and under a forest canopy, and compared their traits with native pi...

The white peach scale (WPS), Pseudaulacaspis pentagona (Targioni-Tozzetti) (Homoptera: Diaspididae), is a world wide polyphagous scale insect. It is widely distributed in north of Iran, near the Caspian Sea areas, where it is the main pest of mulberry and kiwi trees. The development and fecundity of P. pentagona were examined at different temperatures and on different hosts in the laboratory. T...

The purpose of this study was to evaluate the physiological and biochemical changes that occur in mulberry (cv. local and Sujanpuri) plants under alkaline conditions in order to understand the response of these cultivars to alkalinity. Mulberry plants were subjected to different treatments using NaHCO3 and after 20, 40 and 60 days, different physiological and biochemical parameters were studied...

MR 2 variety mulberry leaves were sterilized with UV light for 5, 10 and 15 minutes. These leaves were fed to PM x NB 4 D 2 hybrid silkworm Bombyx mori Linn. life stages and recorded the macromolecular contents (total protein, reducing sugar and glycogen) and digestive enzymes (amylase, invertase and protease) activities. Results revealed feeding of silkworm B. mori with UV treated mulberry lea...

velopment and progression of cerebroand cardiovascular disorders. The pathogenesis of hypertension is accompanied with the increased oxygen free radical production, the decreased nitric oxide bioavailability in the vasculature and reactive oxygen species-mediated cardiovascular remodeling. Hypertensive patients show increased levels of plasma superoxide, hydrogen peroxide and lipid peroxide. In...

abstract more than %90 of natural silk in world is produced by means of mulberry silkworm (bombyx mori l.). therefore, it is important that we recognize and collect mulberry varieties which have high quantity and quality leaf performance. for this purpose, an experiment was conducted with five mulberry varieties (kenmochi, kairyonase, ichinose, shinichinose and local varieties) during two seaso...

We sought to quantify changes in tree species composition, forest structure and aboveground forest biomass (AGB) over 76 years (1930-2006) in the deciduous Black Rock Forest in southeastern New York, USA. We used data from periodic forest inventories, published floras and a set of eight long-term plots, along with species-specific allometric equations to estimate AGB and carbon content. Between...
