Download or read book Texas Master Naturalist Statewide Curriculum written by Michelle M. Haggerty and published by Texas A&M University Press. This book was released on 2019-04-23 with total page 781 pages. Available in PDF, EPUB and Kindle. Book excerpt: For fifteen years, the Texas Master Naturalist program has been hugely successful, training more than 9,600 volunteers who have given almost 2.8 million hours to nature education. This dedicated corps of naturalists provides teaching, outreach, and service in their communities, promoting the appreciation and stewardship of natural resources and natural areas around the state. Hundreds of new volunteers are trained every year, and the Texas Master Naturalist Statewide Curriculum serves as the basis of instruction for trainees who complete a certification course taught under the auspices of more than forty program chapters. The curriculum contains twenty-four units of instruction that range from geology to ornithology to wetland ecology—all written by the state’s top scientists and experts. Available as well to educators, interpreters, and others who may not yet be able to commit to the Texas Master Naturalist program, the curriculum offers an authoritative source of information for anyone seeking to learn more about the natural world in Texas.

Download or read book Wheat Evolution and Domestication written by Moshe Feldman and published by Springer Nature. This book was released on 2023-10-03 with total page 689 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book covers a century of research on wheat genetics and evolution, starting with the discovery in 1918 of the accurate number of chromosomes in wheat. We re-evaluate classical studies that are pillars of the current knowledge considering recent genomic data in the wheat group comprising 31 species from the genera Amblyopyrum, Aegilops, Triticum, and other more distant relatives. For these species, we describe morphology, ecogeographical distribution, phylogeny as well as cytogenetic and genomic features. For crops, we also address evolution under human selection, namely pre-domestication cultivation and domestication. We re-examine the genetic and archeological evidence of where, when, and how domestication occurred. We discuss unique aspects of genome evolution and maintenance under polyploidization, in natural and synthetic allopolyploids of the wheat group. Finally, we propose some thoughts on the future prospects of wheat improvement. As such, it can be of great interest to wheat researchers and breeders as well as to plant scientists and students interested in plant genetics, evolution, domestication, and polyploidy.
