Book Description
For many, the terms aging, maturation and senescence are synonymous and used interchangeably, but they should not be. Whereas senescence represents an endogenously controlled degenerative programme leading to plant or organ death, genetiC aging encompasses a wide array of passive degenerative genetiC processes driven primarily by exogenous factors (Leopold, 1975). Aging is therefore considered a consequence of genetiC lesions that accumulate over time, but by themselves do not necessarily cause death. These lesions are probably made more severe by the increase in size and complexity in trees and their attendant physiology. Thus while the withering of flower petals following pollination can be considered senescence, the loss of viability of stored seeds more clearly represents aging (Norden, 1988). The very recent book "Senescence and Aging in Plants" does not discuss trees, the most dominant group of plants on the earth. Yet both angiospermic and gymnospermic trees also undergo the above phenomena but less is known about them. Do woody plants senesce or do they just age? What is phase change? Is this synonymous with maturation? While it is now becoming recognized that there is no programmed senescence in trees, senescence of their parts, even in gymnosperms (e. g. , needles of temperate conifers las t an average of 3. 5 years), is common; but aging is a readily acknowledged phenomenon. In theory, at least, in the absence of any programmed senescence trees should -live forever, but in practice they do not.

Book Description
In the time since the second edition of The ACS Style Guide was published, the rapid growth of electronic communication has dramatically changed the scientific, technical, and medical (STM) publication world. This dynamic mode of dissemination is enabling scientists, engineers, and medicalpractitioners all over the world to obtain and transmit information quickly and easily. An essential constant in this changing environment is the requirement that information remain accurate, clear, unambiguous, and ethically sound.This extensive revision of The ACS Style Guide thoroughly examines electronic tools now available to assist STM writers in preparing manuscripts and communicating with publishers. Valuable updates include discussions of markup languages, citation of electronic sources, online submission ofmanuscripts, and preparation of figures, tables, and structures. In keeping current with the changing environment, this edition also contains references to many resources on the internet.With this wealth of new information, The ACS Style Guide's Third Edition continues its long tradition of providing invaluable insight on ethics in scientific communication, the editorial process, copyright, conventions in chemistry, grammar, punctuation, spelling, and writing style for any STMauthor, reviewer, or editor. The Third Edition is the definitive source for all information needed to write, review, submit, and edit scholarly and scientific manuscripts.

Book Description
The Holarctic coelotine spiders are revised at the generic level. Coelotine morphology, particularly genitalic morphology, is described, the subfamily and generic limits are defined, and a cladistic hypothesis of generic relationships is presented. The subfamily Coelotinae is defined to include 20 genera and 277 species. The 20 genera are: Ambanus Ovtchinnikov, 1999, with 18 species from far eastern Russia, northeastern China, Japan, and Korea (including 6 new combinations); Asiacoelotes, new genus, with 15 East Asian species (all new combinations, with 3 new synonyms); Bifidocoelotes, new genus, with 2 species from China (both new combinations); Coelotes Blackwall, 1841, with 123 species from Europe and Asia (including 2 new synonyms); Coras Simon, 1898, with 15 North American species and 2 species from China; Coronilla Wang, 1994, with 2 species from China (including 2 new synonyms); Draconarius Ovtchinnikov, 1999, with 26 Asian species (including 25 new combinations and 1 new synonym); Eurocoelotes, new genus, with 11 European species (all new combinations); Femoracoelotes, new genus, with 2 species from Taiwan (both new combinations); Himalcoelotes, new genus, fully revised here, with 10 species from the Himalayas (including 2 new combinations and 8 new species); Leptocoelotes, new genus, with 2 species from China (both new combinations); Longicoelotes, new genus, with 1 new species from China; Paracoelotes Brignoli, 1982, with 16 European and Asian species (including 5 new combinations and 5 new synonyms); Platocoelotes, new genus, with 4 species from China (all new combinations); Robusticoelotes, new genus, with 1 newly combined species from China; Spiricoelotes, new genus, with 2 East Asian species (both new combinations); Tegecoelotes Ovtchinnikov, 1999, with 5 species from far eastern Russia, northeastern China, Japan, and Korea (including 4 new combinations); Tonsilla Wang and Yin, 1992, with 3 species from China; Urocoras Ovtchinnikov, 1999, with 5 species from East Europe (including 2 new combinations); and Wadotes Chamberlin, 1925, with 11 species from North America and 1 from China.
