That text concentrated on the need for farmers, foresters, rangeland managers, and the researchers who advised them to understand better the biology of weeds and the role people play in creating and maintaining weeds in agriculture and other production systems. We were assisted in that first effort by the writings of many early scientists, such as J. L. Harper, H. G. Baker, and E. J.

  • The diversity of bird species is of special importance as it can create responsive and adaptive behaviours among the whole animal population in wild environment. For this reason, the frequent making of inventory lists of bird species helps assess and evaluate the current status of forest resources in natural conservation areas which are inherently under human pressures in our country. During the two years (2009 - 2010) of the study conducted in Huu Lien Nature Reserve in Lang Son province, records have been made of 168 bird species belonging to 117 genus, 54 families, 17 orders.

  • We live in an era with unparalleled opportunities to practice disease prevention based on knowledge of the earth environment. Although globally distributed early warning systems can monitor physical hazards such as earthquakes and tsunamis, chemical hazards on the other hand—whether actual or potential and natural or anthropogenically induced—remain difficult to accurately identify in time and space. Such hazards often have lengthy asymptomatic latency periods before disability or disease becomes evident....
