Download or read book Synecology of the Monotropoideae Within Limpy Rock Research Natural Area Umpqua National Forest Oregon written by Daniel L. Luoma and published by . This book was released on 1987 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: Four aspects of the ecology of members of the Monotropoideae (achiorophyllous Ericaceae, referred to here as "monotropes") are presented: (1) a clarified conceptualization of monotrope nutrition based on a detailed literature review, (2) the relationship of monotrope populations to the plant communities of Limpy Rock RNA, (3) a test of Vreeland's hypothesis concerning the influence of overstory trees on the number of Sarcodes sanguinea plants in a forest stand, (4) the population dynamics of the northernmost known occurrence of Sarcodes san guinea. A literature survey provides insight into the development of concepts concerning the nutritional mode of monotropes. The experimental evidence reviewed showed that the fungi involved have little saprobic ability but are ectomycorrhizal with autotrophic plants. Hence, the concept "epiparasite" can be used to describe an indirect relationship in the life history of monotropes. With consideration of the operational environment of monotropes, however, it can be concluded that the term "epiparasite" is not appropriately used in the context of the nutritional mode of monotropes. Members of the Monotropoideae can be viewed as parasites of their mycorrhizal fungi. Some evidence showed growth of the fungi was stimulated by the presence of monotropes. Since the term "parasite" has negative connotations in general usage, the terms 'obligate mycotroph" and "mycotrophic" may be preferred when referring to members of the Monotropoideae. "Mycotrophic" could be strictly applied to only those organisms which depend on fungi for energy; however, the term has long been used in a broad sense interchangeably with "mycorrhizal." Limpy Rock Research Natural Area is located in the south central portion of the Cascade Mountains in Oregon. The 751 ha (1879 ac.) tract encompasses most of the drainage of Dog Creek. Elevation ranges from 525 to 1305 m (1750 - 4350 ft.). The high species diversity of the Limpy Rock area and local concentration of all eight western monotrope species, provided excellent and possibly unique research opportunities. Coniferous forest vegetation was classified by TWINS PAN into six community types: Pseudotsuga menziesiilAcer circinatum (PSME/ACCI), Pseudotsuga menziesiilCornus nuttalliilBerberis nervosa (PS ME/CONU/B ENE), Pseudotsuga rnenziesii-Arbutus menziesii/Gaultheria shallon-Berberis nervosa/Pleridiurn aquilinum (PS ME-A RME/GAS H- BENE/PTAQ), Pseudotsuga menziesii-Calocedrus decurrens/Gaultheria shallo n-Berberis nervosa (PS MECADE/ GAS H-B ENE), Pseudotsuga menziesii-Calocedrus decurrens/Gauliheria shallon-Berberis nervosa (PS ME-PILA/GAS H-B ENE), Pseudotsuga menziesii- Abies concolor/Berberis nervosal Xerophyllurn tenax (PSME-ABCO/ BENE/XETE). Community types were related to several general environmental measures by detrended correspondence analysis and correlation analysis. Allotropa virgata is strongly preferential to plots at the dryer end of the moisture gradient. Monotropa hypopithys shows a preference for higher elevation and cooler types. Pterospora andromedea was not found in any plots but was noted to be widespread throughout the RNA. Hernitoines con gestwn, Monotropa uniflora, Fityopus californica, and Pleuricosporafiinbrioiata were largely restricted to dryer types. No monotropes were found in plots of the PSME/CONU/BENE or PSME-ARME/GASH-BENE/PTAQ community types. Vreeland's (1980) hypothesis concerning predicting the number of Sarcodes in a stand was reviewed and discussed. In particular, his "Influence Factor" was tested with a data base of over 2000 measurements. The results show his hypothesis to be invalid. Population monitoring of the northernmost known population of Sarcodes sanguinea showed that flowering of individual plants in subsequent years was low in frequency. Despite the low rate of flowering recurrence, population levels were relatively stable over the five years of monitoring.

This book was released on 2012-12-06 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Oata Analysis and Synthesis (CINOAS) * at Purdue. University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 33 (thesis year 1988) a total of 13,273 theses titles from 23 Canadian and 1 85 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 33 reports theses submitted in 1988, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Download or read book Mycoheterotrophy written by Vincent Merckx and published by Springer Science & Business Media. This book was released on 2012-12-09 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the course of evolution, several plant lineages have found ways to obtain water, minerals, and carbohydrates from fungi. Some plants are able exploit fungi to such an extent that they lose the need for photosynthesis. The ability of a plant to live on fungal carbon is known as mycoheterotrophy. This intriguing process has fascinated botanists for centuries, yet many aspects of mycoheterotrophy have remained elusive for a long time. Mycoheterotrophy: The Biology of Plants Living on Fungi explores the biology of mycoheterotrophs, offering general insights into their ecology, diversity, and evolution. Written by renowned experts in the field and bolstered with lavish illustrations and photographs, this volume provides a thematic overview of different aspects of mycoheterotrophy. Comprehensive and readily accessible, Mycoheterotrophy: The Biology of Plants Living on Fungi is a valuable resource for researchers and students who are interested in the process of mycoheterotrophy.

Download or read book The Geographic Mosaic of Coevolution written by John N. Thompson and published by University of Chicago Press. This book was released on 2005-06-15 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coevolution—reciprocal evolutionary change in interacting species driven by natural selection—is one of the most important ecological and genetic processes organizing the earth's biodiversity: most plants and animals require coevolved interactions with other species to survive and reproduce. The Geographic Mosaic of Coevolution analyzes how the biology of species provides the raw material for long-term coevolution, evaluates how local coadaptation forms the basic module of coevolutionary change, and explores how the coevolutionary process reshapes locally coevolving interactions across the earth's constantly changing landscapes. Picking up where his influential The Coevolutionary Process left off, John N. Thompsonsynthesizes the state of a rapidly developing science that integrates approaches from evolutionary ecology, population genetics, phylogeography, systematics, evolutionary biochemistry and physiology, and molecular biology. Using models, data, and hypotheses to develop a complete conceptual framework, Thompson also draws on examples from a wide range of taxa and environments, illustrating the expanding breadth and depth of research in coevolutionary biology.
