This book was released on 2021-01-29 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological collections are a critical part of the nation's science and innovation infrastructure and a fundamental resource for understanding the natural world. Biological collections underpin basic science discoveries as well as deepen our understanding of many challenges such as global change, biodiversity loss, sustainable food production, ecosystem conservation, and improving human health and security. They are important resources for education, both in formal training for the science and technology workforce, and in informal learning through schools, citizen science programs, and adult learning. However, the sustainability of biological collections is under threat. Without enhanced strategic leadership and investments in their infrastructure and growth many biological collections could be lost. Biological Collections: Ensuring Critical Research and Education for the 21st Century recommends approaches for biological collections to develop long-term financial sustainability, advance digitization, recruit and support a diverse workforce, and upgrade and maintain a robust physical infrastructure in order to continue serving science and society. The aim of the report is to stimulate a national discussion regarding the goals and strategies needed to ensure that U.S. biological collections not only thrive but continue to grow throughout the 21st century and beyond.

Download or read book Rhizomania written by Enrico Biancardi and published by Springer. This book was released on 2016-09-20 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: The knowledge of ecology and epidemiology of rhizomania is particularly useful to understand the means and practices able to limit or avoid its further diffusion. Some promising methods of biological control using coexisting and non-pathogenic organisms could potentially help improve the action of the not completely effective genetic resistances. This integrated protection would be valuable, especially in the even more frequent development of resistance–breaking strains in the BNYVV, where the known types of resistance, alone or in combination, seem to have lost part of their original ability to protect the crop. Therefore, further efforts will be needed to discover new traits likely still present in the wild species of the genus Beta. The availability of large collections of germplasm stored in the International Beta gene-banks should ensure the enhanced efficiency of genetic resistance by means of conventional and marker-assisted selection methods. Some almost immune transgenic varieties seem already to be waiting for release where and when it will be possible. The introduction chapter describes briefly the sugar beet crop, the more common diseases, and the damage caused by rhizomania. The following chapters discuss biological properties of the causal virus, BNYVV, and its vector, Polymyxa betae, and their interactions with the environment and the host-plant. In particular, the great advances in research of the molecular biology of BNYVV should be noteworthy, which have been established by a wide range of the most modern methods. Recent work focused on the genetic diversity and evolution of BNYVV is moving forward our understanding of the dramatic worldwide epidemics of rhizomania. Newly developed molecular techniques also lead to practical applications, such as quantification of inoculum in ecological and epidemiological research.

Download or read book Dahlias for the Home written by Benjamin Yoe Morrison and published by . This book was released on 1923 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: No flower is more important in the garden during the late summer and autumn than the dahlia. Its needs are simple and its returns many and generous. If grown in a situation open to sunlight and fresh air but not swept by the winds and if provided with a well-worked fertile soil, neither overwatered nor parched, the dahlia will provide an abundance of beautiful blooms for cutting or garden display. The forms and color variations of the flowers furnish so great a range that almost any personal taste or fancy can be gratified. Dahlias are obtained from nurseries as dormant roots or as growing plants which have been raised from cuttings. Plants may be raised from seed, however. After the season's growth the plants are dug, the tops cut off, and the roots dried off and stored until the following spring in a dark, dry frost-proof cellar. They are then ready to be started into growth and divided into as many pieces as desired or as there are new shoots starting."--Page ii
