Book Description
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.

Book Description
In The Amorite Dynasty of Ugarit Mary Buck pursues a nuanced view of populations in the Bronze Age Levant, with the objective of understanding the ancient polity of Ugarit as a kin-based culture that shares close ties with neighbouring Amorite populations.

Book Description
An indispensable, fully updated guide for everyone interested in identifying, studying, or conserving the flora of New England This comprehensive manual offers accurate, up-to-date, and clear information for identifying New England's remarkable array of tracheophytes (vascular plants, excluding mosses). With fully researched entries on some 3,500 native and nonnative species, the book is the first in decades to provide a complete and correct botanical reference for the region's noncultivated plants. The volume includes many new species not documented in New England before, while also excluding many species that have erroneously appeared in earlier manuals. Focusing on the taxonomy and distribution of New England plants, the manual is largely dedicated to identification keys and to species entries that provide scientific name, origin, regional conservation ranking, common name, synonyms, distribution, ecology, and other miscellaneous items of interest. Nearly one-third of the entries are accompanied by helpful black-and-white line illustrations. Additional special features: Precise distribution information, accurate to the state level Details on unusual plant groups not included in other sources Reliable and versatile keys for identification Tips on recognizing hybrid plants in the field A companion interactive teaching Web site (under development) Comprehensive glossary
