Evolutionary theory is all the rage, but how accurate is the information we are being fed? Jim Alexander casts a critical eye over the new popular concensus, addressing important issues in one of the key debates in modern society.

Protect crop yields and strengthen ecosystems with this essential guide Research into weed management is an increasingly critical component of both environmental stewardship and food production. The potential cost of weed propagation can be measured in crop yield reductions, under-nourished populations, stymied economies, and more. The propagation of herbicide-resistant weed populations means that purely chemical weed management is no longer viable; food production can now be secured only with an ecological approach to weed control. Ecologically-Based Weed Management details such approaches and their potential to manage weeds across a range of agricultural and environmental contexts. It emphasizes the deployment of ecological principles to prevent weed infestations, reduce crop losses, and strengthen ecosystems. In a time when growing population and changing climates are placing enormous pressure on global food production, this approach to weed management has never been more vital. Ecologically-Based Weed Management readers will also find: A global team of expert contributors to a multidisciplinary approach Detailed discussion of topics like herbicide limitation, integrated weed management, and more Insights pertinent to agriculture, academia, government, industry, and more Ecologically-Based Weed Management is ideal for researchers in agriculture chemistry, weed science, agronomy, ecology, and related fields, as well as for regulators and advanced students.

HYDROGEN SULFIDE Covers H2S interactions, methods of detection and delivery in biological environments, and a wide range of applications Research on hydrogen sulfide (H2S) spans diverse disciplines including chemistry, biology, and physiology. In recent years, new materials and approaches have been developed to deliver H2S and related reactive sulfur species in various clinical contexts. Although many biological pathways involving H2S are complex, all are governed by fundamental chemical interactions between reactive sulfur species and other molecular entities. Hydrogen Sulfide: Chemical Biology Basics, Detection Methods, Therapeutic Applications, and Case Studies provides the foundation required for understanding the fundamental chemical biology of H2S while highlighting the compound's therapeutic potential and medicinal applications. This book covers key aspects of H2S chemical biology, including the fundamental chemistry of reactive sulfur species; the measurement, detection, and delivery of H2S in biological environments; and the therapeutic and medicinal uses of exogenous H2S delivery in various pharmacologically relevant systems. Throughout the text, editor Michael Pluth and chapter contributors discuss the opportunities and future of the multidisciplinary field. Provides approaches for delivering H2S with relevance to biological and therapeutic applications Describes complex interactions of H2S with bioinorganic complexes and reactive sulfur, nitrogen, and oxygen species Summarizes advances in available tools to detect, measure, and modulate H2S levels in biological environments, such as real-time methods for H2S fluorescence imaging in live cell and animal systems Helps readers understand known systems and make connections to new and undiscovered pathways and mechanisms of action Includes in-depth case studies of different systems in which H2S plays an important role Hydrogen Sulfide: Chemical Biology Basics, Detection Methods, Therapeutic Applications, and Case Studies is an important source of current knowledge for researchers, academics, graduate students, and industrial scientists in the fields of redox biology, hydrogen sulfide research, and medicinal chemistry of small biological molecules.

Band XIb-2 ist - abgesehen von einigen Ergdnzungen zu den Bdnden XIa und XIb-1 - den Sekunddrstoffen der Papilionoideae gewidmet und bietet einen wohl einmaligen \berblick ]ber die Chemotaxonomie und die sekunddren Inhaltsstoffe dieser Pflanzengruppe. Er ist daher von speziellem Interesse f]r Leguminosenforscher, Pharmakologen, Phytochemiker und Ethnobotaniker. Wie die Bdnde XIa und XIb-1 enthdlt auch dieser Band zahlreiche Literaturhinweise und ein Register mit taxonomischem Index und Stichwortverzeichnis. Dieser letzte Band stellt nach etwa vierzigjdhriger Arbeit den Abschluss der Chemotaxonomie der Pflanzen von Robert Hegnauer dar. Der erste Band erschien 1962; bei der Aufnahme des Autors in die Leopoldina (1972) waren sechs Bdnde abgeschlossen, die alle Familien der hvheren Pflanzen mit Ausnahme der Leguminosen ber]cksichtigten. Diesen Bdnden folgten drei Nachtragsbdnde und ein Generalregister sowie drei Bdnde ]ber Leguminosen.

Plant Nematode Biopesticides presents the most current knowledge on various categories of biopesticides used in the management of nematode pests of crops or those that have significant potential as biological control agents. This book presents an exploratory and investigatory compilation and explanation of the actions and potentials of predatory nematodes, microbial agents, plant and other organic products, nanobiopesticides, and predatory invertebrates as biopesticides of nematode pests of agricultural crops. It is of unique importance and value as the only currently available single-volume resource focusing on plant parasitic nematodes as the pests and biopesticides. In addition, the book addresses common reservations in using biopesticides, either alone or in integrated pest management programs, providing advanced insights on various biopesticidal agents and products. Biopesticides may be microbial (nematodes, bacteria, fungi, virus, herbs etc.), plant-incorporated protectants (PIPs), plant products (citronella oil, neem oil, capsaicin, pyrethrin etc.), synthetic biochemical molecules, pheromones, semio-chemicals, plant extracts, or nanobiopesticides.
