Abstract

Wie gestalten und konstruieren Migrant*innen als Akteur*innen in globalen Bewegungsprozessen ihr Leben und ihr Selbst über territoriale Grenzen hinweg? Welche Rolle spielen digitale Kommunikationstechnologien als Brücke zwischen Herkunfts- und Migrationsland und wie kommen Musik, Theater und Film bei der Bearbeitung von Migrationserfahrungen zum Einsatz? Christina Schachtner untersucht anhand von Gesprächen mit Migrant*innen in Deutschland und Österreich die gesellschaftsverändernde Kraft von Migration. Ihre transdisziplinäre Forschung nimmt insbesondere die Mediennutzung von Migrant*innen in den Blick und umfasst soziologische, psychologische, medien- und kulturwissenschaftliche sowie geschlechtersensible Perspektiven.

Abstract

Magnifiquement imprimé à l’encre argentée sur papier noir, ce guide de terrain de notre nouveau monde de spécimens hybrides catalogue l’amalgame de la technosphère et de la biosphère. Plastiglomérés, chiens robots de surveillance, fordite, gazon artificiel, arbres à antennes, COVID-19, montagnes décapitées, aigles combattant des drones, bananes standardisées : tous ces spécimens – certains plus familiers que d’autres – sont des exemples de l’hybridité qui façonne les paysages actuels de la science, de la technologie et de la vie quotidienne. Inspirés par les bestiaires médiévaux et les effets de plus en plus visibles du changement climatique sur la planète, le chercheur Français Nicolas Nova & et le collectif artistique DISNOVATION.ORG fournissent un guide ethnographique de l’ère « post-naturelle » dans laquelle nous vivons, mettant en évidence les amalgames de nature et d’artifice qui coexistent déjà au 21ème siècle. Sorte de manuel de terrain, Bestiaire de l’Anthropocène vise à nous aider à nous orienter au sein de la technosphère et de la biosphère. Que se passe-t-il lorsque les technologies et leurs conséquences imprévues deviennent si omniprésentes qu’il est difficile de définir ce qui est « naturel » ou non ? Que signifie vivre dans un environnement hybride fait de matière organique et synthétique ? Afin de répondre à ces questions, Nova & DISNOVATION.ORG rassemblent leurs propres recherches avec des contributions de collectifs tels que le Center for Genomic Gastronomy et Aliens in Green ainsi que des textes d’universitaires et de chercheurs du monde entier. La graphiste polonaise Maria Roszkowska fournit des illustrations.

Abstract

The oomycete genus Phytophthora represents one of the most notorious groups of tree pathogens in natural and semi-natural forest ecosystems. Since the discovery in the 1960s of the invasive P. cinnamomi, threatening some of the world’s richest plant communities in Australia, numerous Phytophthora diseases have been reported on forest trees worldwide, which were previously unknown to science. The most notable examples include the oak and beech declines triggered by different Phytophthora spp. in Europe and North America, the findings of sudden oak death and sudden larch death caused by P. ramorum in the Western USA and the U.K., respectively, and the association of P. austrocedri with mal del ciprés in Argentina and juniper decline in the U.K. All these epidemic events are driven by exotic invasive Phytophthora species, introduced through infested nursery plants from their native overseas environments. In recent years, many independent surveys have studied the diversity of Phytophthora species and the diseases they are causing across a diverse range of forests and other natural ecosystems. This Special Issue presents papers on Phytophthora surveys performed in different biogeographic regions and addresses the pathways, and ecological and economic impacts of these invasive forest pathogens.

Abstract

In the past three decades, a stream of criminological inquiry has emerged which explores, measures, and theorizes crimes and harms to the environment at the micro-, mezzo-, and macro-levels. This “green criminology”, as it has come to be known, has widened the criminological gaze to consider crimes and harms committed against air, land (from forests to wetlands), nonhuman animals, and water in local, regional, national, and international areas or arenas. Accordingly, green criminology has endeavored to understand the causes and consequences of air and water pollution, biodiversity loss, climate change, corporate environmental crime (e.g., illegal waste disposal), food production and distribution, resource extraction and exploitation, and wildlife trade and trafficking, while also exploring potential responses to these issues. This book seeks to introduce the green criminological perspective to a broader social science audience. Recognizing that green criminology is not the first social science to explore the phenomena and harms at the intersections of humanity and ecology, this book offers an introduction to some of the unique insights developed over nearly 30 years of green criminological thought and scholarship to students, professors, researchers, and practitioners working in the fields of anthropology, economics, environmental humanities, environmental sociology, geography, history, and political ecology. This book contains contributions from researchers in green criminology from around the world, including early- and mid-career scholars, as well as more established voices in the field—all of whom are dedicated to exposing, understanding, and ultimately hoping to thwart further environmental degradation and despoliation.

Abstract

Apomixis is the consequence of a concerted mechanism that harnesses the sexual machinery and coordinates developmental steps in the ovule to produce an asexual (clonal) seed. Altered sexual developments involve widely characterized functional and anatomical changes in meiosis, gametogenesis, and embryo and endosperm formation. The ovules of apomictic plants skip meiosis and form unreduced female gametophytes whose egg cells develop into a parthenogenetic embryo, and the central cells may or may not fuse to a sperm to develop the seed endosperm. Thus, functional apomixis involves at least three components, apomeiosis, parthenogenesis, and endosperm development, modified from sexual reproduction that must be coordinated at the molecular level to progress through the developmental steps and form a clonal seed. Despite recent progress uncovering specific genes related to apomixis-like phenotypes and the formation of clonal seeds, the molecular basis and regulatorynetwork of apomixis is still unknown. This is a central problem underlying the current limitations of apomixis breeding. This book collates twelve publications addressing different topics around the molecular basis of apomixis, illustrating recent discoveries and advances toward understanding the genetic regulation of the trait, discussing the possible origins of apomixis and the remaining challenges for its commercial deployment in plants.

Abstract

The ability to exploit the potential of wild relatives carrying beneficial traits is a major goal in breeding programs. However, it relies on the possibility of the chromosomes from the crop and wild species in interspecific crosses to recognize, associate, and undergo crossover formation during meiosis, the cellular process responsible for producing gametes with half the genetic content of their parent cells. Unfortunately, in most cases, a barrier exists preventing successful hybridization between the wild and crop chromosomes. Understanding the mechanisms controlling chromosome associations during meiosis are of great interest in plant breeding and will allow chromosome manipulation to introduce genetic variability from related species into a crop. In addition to interspecific hybrids, other materials, such as natural and synthetic polyploids and introgression lines derived from allopolyploids, among others, are powerful tools in the framework of plant breeding. For example, an extra pair of alien chromosomes in the full genome complement of a crop species has been frequently used as a first step to access genetic variation from the secondary gene pool in breeding programs. In addition, such introgression lines are also pivotal in the study of interspecific genetic interactions, in the chromosomal location of genetic markers, and in the study of chromosome structure and behavior in somatic and meiotic cells. Contained in this Special Issue are accounts of original research, including new tools to identify chromosome introgressions and the development and characterization of introgression lines and interspecific hybrids carrying desirable agronomic traits for plant breeding purposes. Also included are reviews about the chromosome engineering of tropical cash crops and the effect of chromosome structure on chromosome associations and recombination during meiosis to allow chromosome manipulation in the framework of plant breeding.
