Biological invasion generates serious threats to global biodiversity. Exotic species usually have high environmental adaptability and tolerance, which is one of the bases their invasion. Except for biological threats, other problems like extreme cold or hot events, soil drought, saline-alkali flood are emerging constantly on a scale. In background multiple interfering with existing habitats, ex...

Advances in biological research likely will permit development of a new class of advanced biological warfare (ABW) agents engineered to elicit novel effects. In addition, biotechnology will have applications supporting ABW weaponization, dissemination, and delivery. Such new agents and delivery systems would provide a variety of new use options, expanding the BW paradigm. Although ABW agents wi...
