Encyclopedia of Environmental Health
Encyclopedia of Environmental Health, Second Edition, Six Volume Set presents the newest release in this fundamental reference that updates and broadens the umbrella of environmental health, especially social and environmental health for its readers. There is ongoing revolution in governance, policies and intervention strategies aimed at evolving changes in health disparities, disease burden, trans-boundary transport and health hazards. This new edition reflects these realities, mapping new directions in the field that include how to minimize threats and develop new scientific paradigms that address emerging local, national and global environmental concerns. Represents a one-stop resource for scientifically reliable information on environmental health Fills a critical gap, with information on one of the most rapidly growing scientific fields of our time Provides comparative approaches to environmental health practice and research in different countries and regions of the world Covers issues behind specific questions and describes the best available scientific methods for environmental risk assessment
Skeletons in confusion: a review of astrophorid sponges with (dicho?)calthrops as structural megascleres (Porifera, Demospongiae, Astrophorida)
Sponges usually obtain their distinct shape and structure by arrangement of mineral or organic skeletal elements (spicules, ?bers). A small group, although provided with spicules, nevertheless is incapable of developing recognizable shapes because the type of structural spicules they have (equal-length four-rayed siliceous elements called calthrops) preclude the possibility of building a cohesive skeleton. Such sponges insinuate themselves in crevices and holes, diminishing the chance of their discovery and collection. The study addresses the taxonomy and biodiversity of two globally distributed genera of these sponges, Dercitus and Calthropella, including the description of ten new species (of 38 species so far documented). The two genera appear similar in spiculation, but they differ in the types of small spicules (microscleres). This induces a discussion of their phylogeny and classi? cation: are they closely related or is it convergent evolution? No proposals are made for a rearranged classi? cation pending independent evidence from molecular studies.
Ethnobotany and Ethnopharmacology of Medicinal and Aromatic Plants
Medicinal and aromatic plants are beneficial to human health. Plant-derived molecules possess biological activities that can be used to prevent many infectious diseases and metabolic disorders. Ethnobotany and Ethnopharmacology of Medicinal and Aromatic Plants summarizes techniques and methods used to study the biological activities of plant-derived extracts and compounds to study ethnobotanical and ethnopharmacological features of medicinal and aromatic plants. This book: Includes computational approaches to study the pharmacological properties of biomolecules in medicinal and aromatic plants. Details methods in ethnopharmacology including chromatographical and analytical techniques. Demons...
Biogeography, Time and Place: Distributions, Barriers and Islands
This book offers exchanges between the fields of paleontology and zoology as patterns of biodiversity have long attracted the attention of both biologists and paleontologists. It covers the development of isolated island faunas, paleogeography and zoomorphology. The book shows that patterns are not always what they seem if looked at without a spatial or temporal reference.
Systema Porifera
Research whilst compiling this book has uncovered a fauna about twice the size as that previously published in the literature and consequently Systema Porifera revises and stabilizes the systematics of the phylum to accommodate this new knowledge in a contemporary framework. Practical tools (key illustrations, descriptions of character) are provided to facilitate the assignment of approximately 680 extant and 100 fossil genera. Systema Porifera is unique making sponge taxonomy widely available at the practical level of classification (genera, families, order). It is a taxonomic revision of sponges and spongiomorphis (such as sphinctozoans and archaeocyathans) based on re-evaluation of type m...
Bioprospecting
This book considers all aspects of bioprospecting in 14 succinct chapters and a forward by David Hawksworth. The organisms addressed include plants, insects, fungi, bacteria and phages. Bioprospecting has never been more relevant and is of renewed interest, because of the extremely worrying rise in novel, resistant pathogenic microorganisms. The practices in pharmaceutical companies have failed to deliver novel antibiotics to control these infections. We need to look for new sources of drugs from the environment on a massive scale as drug discovery is “too important to fail”. Furthermore, the field can add great value to ecosystems in terms of economics, while providing additional reason...
