The mid-altitude zone of the Qinling Mountains in China was once dominated by birch and pine-oak belts but are now mainly covered by secondary growth following large-scale deforestation. Assessing the recovery and sustainability of these forests is essential for their management and restoration. We investigated and compared the tree species composition and community assemblages of secondary for...

Because of its unique colony form Bacillus mycoides has been a favorite species for the study of dissociation and life cycles. The mutually confirmatory reports of Nyberg (1929), Lewis (1932) and den Dooren de Jong (1933) have shown that this species is characterized by marked colonial polymorphism and that the sequence of events in dissociation is readily followed in cultures. So far as we are...

BACKGROUND AND AIMS During their lifetime, tree stems take a series of successive nested shapes. Individual tree growth models traditionally focus on apical growth and architecture. However, cambial growth, which is distributed over a surface layer wrapping the whole organism, equally contributes to plant form and function. This study aims at providing a framework to simulate how organism shape...

The rapid population growth and increasing economic activities have resulted in the tremendous growth of motor vehicles which is considered one of the primary factors responsible for increasing road accidents in many metropolitan cities of developing countries, including Kolkata, India. In this paper an assessment of the current level of road safety in Kolkata is made utilizing data obtained fr...
