Octavo,112 pp.,softcover. Royal Ornithologists Union Monograph 2.

Large octavo,277 pp.,fine copy in laminated boards. Includes the standard Australian bird checklist and covers the systematics and taxonomy of the Australian avifauna. An essential reference for all seriously interested in the subject. A major revision of the previous checklist published in 1994. Lists those species of birds that have been recorded from the Australian mainland, Tasmania, island territories and surrounding waters. Based on the authors' original book The taxonomy and species of birds of Australia and its territories, it includes any new species for which records have been accepted by the Records Appraisal Committee of Birds Australia. It also includes all extant and recently extinct (post-1800) native species, as well as new species, accepted vagrants and introduced species that have become established and continue to survive in the wild. The book provides brief explanations for taxonomic changes in the literature and for those adopted within it, including the citations for such work. Its geographical coverage includes Christmas Island, Cocos-Keeling Islands, Heard Island, Lord Howe Island, Macquarie Island, Norfolk Island and the islands of Torres Strait, and also Ashmore Reef, owing to the number of vagrant species that have recently been reported from there. Also included are vagrants from the Australian Antarctic Territory that have not been recorded elsewhere in Australia or its territories. …

Hardcover. Condizione: New. This book reveals the remarkable new history of how passerines diversified and dispersed across the entire world. It also presents and explains the new classification, which reflects the phylogenetic history. The new insights reveal that many of the old evolutionary lineages comprise only a few species that remained in their area of origin or underwent limited dispersal. Only a small number of groups underwent significant proliferation of new species and just five (of 145) passerine families are represented on all continents but Antarctica. Even so, the global variation in species richness generally correlates well with the variation in productivity across different environments. We see how a seemingly constant overall rate of evolution of new species is possible because of rapid proliferation in new ecological niches, including archipelagos, and an extraordinary accumulation of endemic species in certain tropical mountain ranges.In addition to describing the revised evolutionary history of passerine birds, the authors try to identify adaptational changes, including shifts in life history strategies, that underlie major evolutionary expansions. Their aim is to further the development of a unified theory to explain how the prodigious variation of Earth?s biodiversity is generated.Measurements: 12.5 x 9.5 x 1.25 inches, 24 × 31 cm.…

Condizione: New. Idioma/Language: Inglés. Esta obra presenta la nueva y extraordinaria historia de cómo las aves paseriformes se diversificaron y dispersaron por todo el mundo. También describe la nueva clasificación que refleja su historia filogenética. La nueva filogenia revela que muchos de los linajes evolutivos más antiguos comprenden solo unas pocas especies que permanecieron en su área de origen o sufrieron una dispersión limitada. Solo un pequeño número de grupos experimentó una proliferación significativa de nuevas especies y, de hecho, solo cinco (de 145) familias de paseriformes están representadas en todos los continentes (excepto la Antártida). Sin embargo, la variación global de la riqueza de especies generalmente está relacionada con los cambios en la productividad en los distintos hábitats. Una tasa de evolución global de nuevas especies aparentemente constante parece posible debido a la rápida proliferación en nuevos nichos ecológicos y en archipiélagos, y una acumulación extraordinaria de especies endémicas en algunas cadenas montañosas tropicales. Además de describir la historia evolutiva revisada de las aves paseriformes, los autores intentan identificar sus cambios adaptativos, incluidos cambios en las estrategias vitales, subyacentes a las expansiones evolutivas más significativas. Su objetivo es contribuir al desarrollo de una teoría unificada para explicar cómo se ha generado la gran variación de la biodiversidad en la Tierra. *** Nota: Los envíos a España peninsular, Baleares y Canarias se realizan a través de mensajería urgente.
