Recent years have witnessed a rapid rise in engagement with emotion and affect across a broad range of disciplines in the humanities and social sciences, with geographers among others making a significant contribution by examining the emotional intersections between people and places. Building on the achievements of Emotional Geographies (2005), the editors have brought together leading scholars such as Nigel Thrift, Alphonso Lingis and Frances Dyson as well as young, up and coming academics from a diverse range of disciplines to investigate feelings and affect in various spatial and social contexts, environments and landscapes. The book is divided into five sections covering the themes of remembering, understanding, mourning, belonging, and enchanting.

The result is the most comprehensive elucidation of the evolutionary relationships of the Asteraceae and of the groups within it, and an exhaustive classification of the family. All available information on the phylogeny of the family has here been assembled in one volume; included are more than 50 cladograms and phylogenetic trees, many of them from new and hitherto unpublished cladistic analyses. In addition to introductory chapters on cladistics, classification, morphology, and evolution, the book also includes chapters on each of the sub-families and tribes, with illustrations of morphological details, as well as descriptions of all genera. Several of these chapters were provided by Arne A. Anderberg, Per Ola Karis, Bertil Nordenstam, Johannes Lundberg, and Olof Ryding, from the Swedish Museum of Natural History in Stockholm and from the Department of Systematic Botany at Uppsala University, Sweden.
Early biogeographers such as Alexander von Humboldt recognized the broad-scale coupling of vegetation and climate. This observation shaped the modern biome concept which organizes ecosystems by assumed relationships to environmental controls. This approach has been criticized for missing key impacts on the distribution and functioning of biomes like historical contingency, biogeographic history, disturbance ecology, and evolution. Are biomes still a convenient framework for organizing our understanding of biodiversity? What factors determine the functional differences among and within biomes, and at what spatial, temporal, and phylogenetic scales are those drivers most important? How can we better represent the functional characteristics and dynamics of ecosystems? This Research Topic highlights the latest discussions and research on biomes, drawing from a wide range of approaches spanning from macroecology and phylogeography to remote sensing and modelling ecosystem responses to global change.
"This spectacular book does full justice to the Compositae (Asteraceae), the largest and most successful flowering plant family with some 1700 genera and 24,000 species. It is an indispensable reference, providing the most up-to-date hypotheses of phylogenetic relationships in the family based on molecular and morphological characters, along with the corresponding subfamilial and tribal classification. The 2009 work not only integrates the extensive molecular phylogenetic analyses conducted in the last 25 years, but also uses these to produce a metatree for about 900 taxa of Compositae. The book contains 44 chapters, contributed by 80 authors, covering the history, economic importance, chara...
This text summarizes the results of studies on the pollination ecology of the unique family Compositae (Asteraceae). The complex structural and functional specializations of the capitulum (or head) for pollinator attraction and pollen transfer are described in detail. An attempt is made to identify the influence of these specializations on the development and the function of other floral parts. The remarkable sex polymorphism of the Compositae head, which has caused much confusion amongst students is traced to this influence and characterized as a secondary modification. The central concept in the book is taht pollination ecology is the guiding factor in Compositae evolution.
Far Off Metal River examines how explorer Samuel Hearne’s account of the alleged 1771 “Bloody Falls massacre” in the Central Arctic has shaped ongoing colonization and economic exploitation of the North. As Emilie Cameron demonstrates, the Arctic has for centuries been treated like a blank page onto which a long line of explorers, missionaries, anthropologists, resource companies, and politicians have inscribed stories that serve their own interests. These stories have played a central role in shaping the region, including efforts to open the North to industrial resource extraction. Consequently, Qablunaat (non-Inuit, non-Indigenous people) have a responsibility to question their relationships with the North and northerners, first by placing these stories within their proper historical, geographical, and social context, and then by developing new understandings and new relationships that reflect the actual political, cultural, economic, environmental, and social landscapes of the contemporary Arctic.landscapes of the contemporary Arctic.
