Rice yields need to increase in order to keep pace with the growing population of Asia and to alleviate hunger and poverty. There appears, however, to be a biophysical limit associated with conventional photosynthetic pathways. The research presented in this book aims at understanding how the rice plant's photosynthetic pathway could be redesigned to overcome current yield limits. The factors controlling yield are discussed from the agronomic to the molecular level. Prospects for improving rice photosynthesis include using genetic engineering to convert rice into a C4 plant.The various chapters in this book deal with photosynthesis; a comparison of C3 and C4 pathways; genes physiology and function, and also discuss this in the broader context of economic consequences of yield improvements for poverty, the molecular genetics of photosynthesis, and ecophysiological and evolutionary perspectives of photosynthesis in wetlands.Researchers on rice, photosynthesis, agronomy, genetic engineering, and food policy will find much of interest in this book.
The two most species-rich radiations of gall-inducing eriococcids are parasites of Eucalyptus: (1) the genus Apiomorpha R?bsaamen (ca 40 described species and many undescribed cryptic species), and (2) a monophyletic group composed of species currently placed in the genera Lachnodius Maskell, Opisthoscelis Schrader, Sphaerococcopsis Cockerell, Fragorbis Hardy and Gullan and Floracoccus Beardsley (ca 30 described species). We revise the genus Opisthoscelis Schrader, and erect the genus Tanyscelis gen. n. with Opisthoscelis pisiformis Froggatt as its type species. As a result of our taxonomic revision, Opisthoscelis has six species and Tanyscelis has 12 species. We describe the adult female and female gall of each species and galls of males for 10 species of Opisthoscelis and Tanyscelis, and provide photographs of the galls for most species. A key to the adult females of the species of both genera is included.
Islands are special places; they can be havens for unique plants and animals and refuges for wildlife. This book investigates the biogeography of butterfly species over the British islands, particularly the factors that influence their presence on the islands and that have made each island's butterfly fauna distinctive. The book contains a full log of records of species on the islands and much supporting information. The first three chapters set the scene, illustrating the basics of island biogeography theory, their changing circumstances during the current Holocene interglacial, and studies of natural history of British butterflies that mark the islands as the most intensively studied region for wildlife in the world. The book advances by increasing resolution downscale from a European continental perspective, through patterns and changes on the British mainland, a comparison of the two dominant islands of Britain and Ireland, to a close inspection of the dynamics of species on the multitude of offshore islands. Detailed investigations include contrasts in species' richness on the islands and then of the incidences of each species. Case studies highlight the continual turnover of species on islands. Attention is then given to evolutionary changes since the time that glaciers enveloped Europe. A powerful message is conveyed for the maintenance of butterfly species on the smaller British islands now experiencing population losses at a rate unprecedented since the spread of the last ice sheets: the incontrovertible importance of maintaining populations of species on nearby mainland sources for islands as pools for future migrants.
Child beauty pageants are a phenomenon in rural communities throughout the American South. Girlhood, Beauty Pageants and Power: Trailer Park Royalty explores the participants who compete in these pageants and shows that most are from the lower socio-economic bracket. A bricolage of post-structural feminism, critical ethnographies, critical hermeneutics, and cultural studies lenses analyzes how the performances of participants and the power exercised by the beauty pageant culture work to formulate girls' identities. Analysis in Girlhood, Beauty Pageants and Power will also include how power operated to perpetuate this subculture and its right to dictate norms for beauty and acceptance and will be situated in the culture of girlhood. Examination of what is depicted in popular culture through film, videos, documentaries, and television shows will also add to the dialogue. I suggest that the rural beauty pageant culture does work to create girlhood identity and a way in which the participants view the world and themselves. In fact, I believe that the rural beauty pageant culture does intricate cultural work in terms of gender and class. This book is intended for students and teachers who are interested in dissecting rural girlhood and development, Southern American beauty standards, and the effect of the media on girls' identities.
In Leading a Competency-Based Secondary School: The Marzano Academies Model, authors Robert J. Marzano and Patrick B. Hardy outline how secondary school leaders can implement an effective competency-based education system. Based on decades of research and refined in the Marzano Academies, the model presented in this book will aid schools in the process of shifting from a traditional school to a high reliability, competency-based organization. The authors identify sixteen leading indicators leaders use to measure their high reliability status, and they share a process to create and address lagging indicators based on collected data. By reading Leading a Competency-Based Secondary School, middle and high school leaders will receive research-based strategies and tools to target specific indicators and guide their schools to mastery of these indicators"--
