影響因子Topics for the Beltsville Symposia are selected to highlight specific areas of research and science policy that are of concern to scientists in the Beltsville Area as well as to the general scientific community. Each sympo- sium in the series is structured to provide a realistic appraisal of current findings, research progress, and relevant policy issues within the constraints established by the organizing committee. Thus, the presentations and dis- cussions that have marked these symposia have had a strong appeal to the broad community of scientists. Knowledge of the diversity of living organisms is still quite limited. Since the time of Linnaeus, about 1.7 million species have been described. The actual number has been estimated between 5-50 million. Many species, land races, and strains are vanishing. Clearly, the world‘s scientific institutions are inadequately equipped to attain sufficient knowledge of a significant fraction of the diverse living forms. Also, efforts in the collection and preservation of germplasm of plants and animals urgently need to be strengthened. These mattes are critically important to future generations. This symposium addresses vital concerns of bioti

Dennis Campbell,David S. Tenzerons also provide a marvelously efficient system for communication and they enable various levels of prediction. Unfortunately, systematics and biological diversity are generally misunderstood because the general populace holds a simplistic view of the complexity and size of the world’s biota. Decima

Unlike other resourses, once cell life is lost, the germplasm is lost, therefore for all practical purposes it is stored only in living systems. For convenience germplasm resources can be grouped into several levels of usefulness and management:.Germplas

The simple activities of farmers and herders have sufficed to insure that nature and all its diversity would remain safe from harm..It was not until the last several decade
