Abstract

The average person can name more bird species than they think, but do we really know what a bird “species” is? This open access book takes up several fascinating aspects of bird life to elucidate this basic concept in biology. From genetic and physiological basics to the phenomena of bird song and bird migration, it analyzes various interactions of birds – with their environment and other birds. Lastly, it shows imminent threats to birds in the Anthropocene, the era of global human impact. Although it seemed to be easy to define bird species, the advent of modern methods has challenged species definition and led to a multidisciplinary approach to classifying birds. One outstanding new toolbox comes with the more and more reasonably priced acquisition of whole-genome sequences that allow causative analyses of how bird species diversify. Speciation has reached a final stage when daughter species are reproductively isolated, but this stage is not easily detectable from the phenotype we observe. Culturally transmitted traits such as bird song seem to speed up speciation processes, while another behavioral trait, migration, helps birds to find food resources, and also coincides with higher chances of reaching new, inhabitable areas. In general, distribution is a major key to understanding speciation in birds. Examples of ecological speciation can be found in birds, and the constant interaction of birds with their biotic environment also contributes to evolutionary changes. In the Anthropocene, birds are confronted with rapid changes that are highly threatening for some species. Climate change forces birds to move their ranges, but may also disrupt well-established interactions between climate, vegetation, and food sources. This book brings together various disciplines involved in observing bird species come into existence, modify, and vanish. It is a rich resource for bird enthusiasts who want to understand various processes at the cutting edge of current research in more detail. At the same time it offers students the opportunity to see primarily unconnected, but booming big-data approaches such as genomics and biogeography meet in a topic of broad interest. Lastly, the book enables conservationists to better understand the uncertainties surrounding “species” as entities of protection.

Abstract

Marine bacteria and archaea are key players in the biogeochemical cycling of nitrogen, carbon, and other elements. One important lineage of marine bacteria is the Roseobacter group. Members of this clade are the most abundant bacteria in marine ecosystems constituting up to 25% of the marine bacterioplankton. They have been detected in various marine habitats from coastal regions to deep-sea sediments and from polar regions to tropical latitudes. These bacteria are physiologically and genetically very versatile. Utilization of several organic and inorganic compounds, sulfur oxidation, aerobic anoxygenic photosynthesis, carbon monoxide oxidation, DMSP demethylation, and production of secondary metabolites are some of the important functional traits found in this clade. Moreover, several isolates are available allowing in-depth analysis of physiological and genetic characteristics. Although the Roseobacter group has been intensively studied in recent years, our understanding of its ecological contributions and the evolutionary processes shaping the genomes of this clade is still rather limited.

Abstract

Covert Plants contributes to newly emerging discourses on the implications of vegetal life for the arts and culture. This stretches to changes in our perception of ‘nature’ and to the adapting roles of botany, evolutionary ecology, and environmental aesthetics in the humanities. Its editors and contributors seek various expressions of vegetal life rather than the mere representation of such, and they proceed from the conviction that a rigorous approach to thinking with and through vegetal life must be interdisciplinary. At a time when urgent calls for restorative care and reparative action have been sounded for the environment, this essay volume presents a range of academic and creative perspectives, from evolutionary biology to literary theory, philosophy to poetry, which respond to the perplexing problems and paradoxes of vegetal thinking. Representations of vegetal life often include plant analogies and plant imagery. These representations have at times obscured the diversity of plant behavior and experience. Covert Plants probes the implications of vegetal life for thought and how new plant science is changing our perception of the vegetal — around us and in us. How can we think, speak, and write about plant life without falling into human-nature dyads, or without tumbling into reductive theoretical notions about the always complex relations between cognition and action, identity and value, subject and object? A full view of this shifting perspective requires a ‘stereoscopic’ lens through which to view plants, but also simultaneously to alter our human-centered viewpoint. Plants are no longer the passive object of contemplation, but are increasingly resembling ‘subjects,’ ‘stakeholders,’ or ‘actors.’ As such, the plant now makes unprecedented demands upon the nature of contemplation itself. Moreover, the aesthetic, political, and legal implications of new knowledge regarding plants’ ability to communicate, sense, and learn require intensive, cross-disciplinary investigation. By doing this, we can intervene into current attitudes to climate change and sustainability, and hopefully revise, for the better, human philosophies, ethics, and aesthetics that touch upon plant life.

Abstract

Religion is much queerer than we ever imagined. Nature is as well. These are the two basic insights that have led to this volume: the authors included here hope to queerly go where no thinkers have gone before. The combination of queer theory and religion has been happening for at least 25 years. People such as John Boswell began to examine the history of religious traditions with a queer eye, and soon after we had the indecent theology of Marcella Althaus Ried. Jay Johnston, one of the authors in this issue, is among those who have used the queer eye to interrogate authority within Christian theological traditions. At the same time, there have been many queer interrogations of “nature,” perhaps most notably in the works of Joan Roughgarden and Ann Fausto-Sterling, and more recently in the works of Catriona Sandilands and Timothy Morton (an author in this volume). However, the intersections of religion, nature, and queer theory have been largely left untouched. With the exception of Dan Spencer, who writes the introduction for this volume and is one of the early pioneers in this realm of thought with his book Gay and Gaia (Pilgrim Press, 1996), and the work of Greta Gaard in developing a queer ecofeminist thought, religion and nature, or religion and ecology, have largely ignored the realm of queer theory. In part, the blinders to queer theory on the part of eco-thinkers (religious or otherwise) are similar to the blinders eco-thinkers have when it comes to postmodern thought in general: namely, if there are no absolute foundations, how does one create an environmental ethic and a “nature” to save? For this reason and many others, this volume on religion, nature, and queer theory is groundbreaking. Though these essays span many different disciplines and themes, they are all held together by the triple focus on religion, nature, and queer theory. Each of these essays offers a unique contribution to the intersection of religion, nature, and queer theory, and all of them challenge strict boundaries proposed in religious rhetoric and many discourses surrounding “nature.” Carol Wayne White’s essay draws from a queer reading of James Baldwin to develop an African American religious naturalism, which highlights humans as polyamorous bastards. Jacob Erickson’s essay examines Isabella Rossellini’s “Green Porno” and Martin Luther’s work to develop an irreverent theology. Jay Johnson draws from personal relationships with his late dog, and Master/Pup fetish-play, to blur the boundaries between humans and other animals, specifically within ethical and theological discourse. Whitney Bauman reflects on how the very processes of globalization and climate change queer our identities and call for a queer and versatile planetary ethic. Finally, Timothy Morton leads us through a reflection on queer green sex toys to challenge the ontology of agrologistics. Each of these essays in their own way is concerned with fleshing out more meaningful encounters with the planetary community. Without being too ambitious, we hope that these sets of essays will help to open up a new trajectory of conversations at the intersection of religion, nature, and queer theory.

Abstract

Cassava is a staple food for many nations owing to its resilience for growth under various climatic conditions. It is a good source of carbohydrates and is the third largest source of food carbohydrates in the tropics, after rice and maize. This book focuses on the morphological traits and nutritive properties of cassava and its production processes, postharvest techniques and diseases that affect the growth of the crop. Given its extensive usage and market value, it is one of the agricultural produces for which many biotechnological interventions have been applied for ascertaining food security. It is hoped that readers will gain knowledge on cassava as well as use some of the techniques mentioned herein for improvement of the production of the crop.

Abstract

This book concerns the different aspects of forest fires, the impact of fire on both forest resources (e.g. forest cover) and communities that use different forest functions. Therefore, forest fires have their environmental, economic and social consequences, and none of them is less important. Forest fires can be caused by both natural forces and anthropogenic factors, and in the latter case, it is extremely interesting to profile the potential arsonist. Forest fires may also cause conflicts, stronger or weaker, in local communities that have been using forests for years. These conflicts can be solved both by gradually changing the law itself and through education at the local level. Not less important is the ability to detect fires early, which can be helped by the development of modern technologies. In limiting the effects of forest fires, it may also be helpful to develop mathematical models that indicate various factors affecting the possibility of a fire or affecting the rate of its spread. Not less important is the attempt to assess the direction of forest regeneration after the fire has ceased, in understanding what the help of modern technology is. These aspects of forest fire are the subject of this book. I realize, however, that the contents in it can only be an incentive for the reader to learn more, in an interesting aspect. I assume that this book will be valuable to researchers as well as students who are interested in different aspects connected to forest fires, not only from the ecological point of view but also from the social one. Both are extremely important in future forest protection and sustainable use of forest by local communities.

Abstract

Forests grow and their biomass increases; they absorb carbon from the atmosphere and store it in plant tissue. Understanding the biomass of forest vegetation is essential for determining the storage of carbon in the dominant tree component and computing carbon cycling at a regional as well as global level. This book consisting of five chapters will give a comprehensive understanding of biomass production vis-

Abstract

Virtuous Waters is a pathbreaking and innovative study of bathing, drinking and other everyday engagements with a wide range of waters across five centuries in Mexico. Casey Walsh uses political ecology to bring together an analysis of shifting scientific, religious and political understandings of waters and a material history of social formations, environments, and infrastructures. The book shows that while modern concepts and infrastructures have come to dominate both the hydrosphere and the scholarly literature on water, longstanding popular understandings and engagements with these heterogeneous liquids have been reproduced as part of the same process. Attention to these dynamics can help us comprehend and confront the water crisis that is coming to a head in the twenty-first century.
