The Ecology of Bird Communities
de John A. Wiens(Ed. Cambridge University Press) Isbn : 0521426340
79.79 €
These two books represent a synthesis and critical evaluation of studies conducted on bird communities, or sets of bird species that occur together. Drawing from studies conducted throughout the world, they review in detail what is known about the patterns of organization of such communities and the factors, such as competition, predation, past history, climate, habitat or disturbance that may determine these patterns. In Volume 1, the author considers why the avian community ecologists ask the questions they do, and how they have proceeded to answer them. The questions have generally involved both«what»(pattern) and«why»(process) components. Most of the volume is devoted to a critical evaluation of the patterns of bird communities. In Volume 2, the author considers how community organizat...

Be Stars: Proceedings of the Paris Workshop Held from 9-12 June, 1997
de Anne M. Hubert, Carlos Jaschek(Ed. Springer) Isbn : 0792352084
128.98 €
These proceedings provide a broad overview of the research carried out to date on B-type stars with forbidden emission lines and dusty envelopes. These objects may represent an important transition stage in the evolution of many early-type stars, but they have been little studied until now. The book brings together the information available on the distribution, absolute magnitude, spectra in all wavelength ranges, photometric properties and variability of these objects. Also discussed are the different theoretical models proposed for explaining the amazing variety of phenomena observed.

Cataclysmic Variables: Proceedings of the Conference Held in Abano Terme, Italy, on 20-24 June 1994 (Astrophysics Space Science Library)
de 41982(Ed. Kluwer Academic Publishers) Isbn : 0792336763
94.06 €
These proceedings present new observational and theoretical results on cataclysmic variables (CV's). Main topics include: interrelations among CVs; theory and evolution of classical, recurrent, symbiotic novae; dwarf novae, nova-like and accretion-induced phenomena; the role of magnetic fields in CV evolution; CVs as possible precursors of SNI-a; links between CVs and super-soft X-ray sources. Audience: Astronomers interested in cataclysmic variables.

Instability and Variability of Hot-Star Winds: Proceedings of an International Workshop Held at Isle-aux-Coudres, Quebec Province, Canada, August 23-27, 1993
de 38905(Ed. Kluwer Academic Publishers) Isbn : 0792333314
94.06 €
These proceedings of a workshop held at Isle-aux-Coudres, Quebec, Canada in August 1993, provide a comprehensive, up-to- date assessment of a fundamental subject in modern stellar astrophysics. Hot, luminous stars play a crucial role in the rapid recycling of matter in dense regions of the Universe. The most luminous objects generate the strongest outflows of material, which in turn have a profound impact on both the interstellar medium and the underlying stars themselves. However, recent observational and theoretical advances have shown that these outflows are highly unstable and inhomogeneous. These characteristics constitute a fundamental property of the outflows that can no longer be disregarded. Instability and Variability of Hot-Star Winds provides an in-depth assessment of this impo...

The Upland Bird Art of Maynard Reece
de Maynard Reece(Ed. Harry N. Abrams, Inc.) Isbn : 0810939363
47.02 €
These oil and watercolor paintings of upland birds--pheasant, grouse, quail, wild turkey, ptarmigan, snipe, among others--amply display Reece's realistic style. The artist, who worked for many years as an outdoor-magazine illustrator, likes to ``paint from the sportsman's view'' (as Roger Tory Peterson notes in his introduction), catching birds flushing and fleeing, whirring through the air. He is also an able field naturalist, complementing his artwork with habitat notes of midwestern prairie, forest, and marsh, as well as behavioral tidbits gleaned from the field; were it not oversized, Reece's work would make a useful field guide. While the birds command center stage, what steals the show are Reece's superb landscape settings, from the disheveled sweep of a mown cornfield to the intimat...
