Book Synopsis The Oligocene Bridge Creek Flora of the John Day Formation, Oregon by : Herbert William Meyer
Download or read book The Oligocene Bridge Creek Flora of the John Day Formation, Oregon written by Herbert William Meyer and published by . This book was released on 1997 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive systematic revision of the Bridge Creek flora is based on large collections of megafossil specimens from the John Day and Crooked River basins. The flora was found to be more diverse than previously recognized, with at least 125 species. At least 11 genera are extinct, but the majority are extant members of deciduous forests. The flora was derived from a variety of sources and represents a classic example of the broadleaved deciduous forests that became widespread at mid-latitudes following the Eocene-Oligocene climatic cooling.

Book Synopsis The Geobiology and Ecology of Metasequoia by : Ben A. LePage
Download or read book The Geobiology and Ecology of Metasequoia written by Ben A. LePage and published by Springer Science & Business Media. This book was released on 2005-07-22 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: The plant fossil record indicates that the genus Metasequoia was widely distributed throughout the Northern Hemisphere from the early Late Cretaceous to the Plio-Pleistocene. Today the genus has shrunk to one species with approximately 5,000 mature individuals in southeastern China’s Xiahoe Valley. This book distills the current understanding of the biology, ecology and physiology of fossil and living Metasequoia, current research directions and problems that remain unresolved.

Book Synopsis The Oligocene Haynes Creek Flora of Eastern Idaho by : Daniel I. Axelrod
Download or read book The Oligocene Haynes Creek Flora of Eastern Idaho written by Daniel I. Axelrod and published by Univ of California Press. This book was released on 1998-07-31 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: This flora of 70 species is dominated by deciduous trees, many with descendants in China. Precipitation was 890 mm, mean annual temperature 12.5°C, the annual range 10°C, and freezing rare. Elevation was about 1000 meters. Comparison with the Horse Prairie flora, 30 miles east and across the present continental divide, indicates that the divide was then low and discontinuous, with warmer climate to the east.

Showcasing the region's geological diversity, the peer-reviewed papers included here span topics ranging from accreted terrains and mantle plumes to volcanoes, floods, and vineyard terroir. Locations visited throughout Oregon, Washington, and Idaho encompass Astoria to Zillah. More than just a series of maps, the accompanying descriptions, observations, and conclusions offer new insights to the geologic processes and history of the Pacific Northwest - insights that will inspire readers to put their boots on the evidence as they develop their own understanding of this remarkable and dynamic corner of the world."--Publisher's description.
Book Synopsis A Miocene (10-12 Ma) Evergreen Laurel-Oak Forest from Carmel Valley, California by : Daniel I. Axelrod
Download or read book A Miocene (10-12 Ma) Evergreen Laurel-Oak Forest from Carmel Valley, California written by Daniel I. Axelrod and published by Univ of California Press. This book was released on 2000-06-12 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a study of the Miocene Carmel flora of California, an evergreen laurel–oak forest that grew in a mild temperate (mean annual temperature of 15 degrees C), frost-free climate, with annual precipitation of about 760 mm (30 in.). Collectively, the Carmel and other Miocene floras like the San Pablo and Temblor (broad-leafed deciduous trees, with few evergreen species), the Puente (evergreen oak forest with chaparral species), the Mint Canyon, Ricardo, and Tehachapi (numerous arid subtropical scrub associated with oak woodland and chaparral species) suggest they foreshadowed a similar distribution of the different California vegetation zones today.
