This book examines the critical issue of environmental pollutants produced by the textiles industry. Comprised of contributions from environmental scientists and materials and textiles scientists, this edited volume addresses the environmental impact of microplastics, with a particular focus on microfibres released by textiles into marine and freshwater environments. The chapters in Part I offer environmental perspectives focusing on the measurement of microplastics in the environment, their ingestion by small plankton and larger filter feeders, the effects of consuming microplastics, and the role of microplastics as a vector for transferring toxic contaminants in food webs. Written by environmental and material scientists, the chapters in Part II present potential solutions to the problem of microplastics released from textiles, discussing parameters of influence, water treatment, degradation in aquatic environments, textile end-of-life management, textile manufacturing and laundry, and possible policy measures. This is a much needed volume which brings together in one place environmental research with technical solutions in order to provide a cohesive and practical approach to mitigating and preventing environmental pollution from the textiles industry going forward. This book will be of great interest to students and scholars of environmental conservation and management, environmental pollution and environmental chemistry and toxicology, sustainability, as well as students and scholars of material and textiles science, textile engineering and sustainable manufacturing.

Those who are involved with fishing and fisheries resource management--including fishermen, their communities, production, processing, distribution, and marketing industries, and various government and non-governmental organizations--confront the contradictions arising from the appropriation, allocation, and distribution of fisheries and marine resources in a variety of ways.

The authors call into question the assumptions of policy prescriptions to common resource problems by examining the experiences of people and societies confronted with and adapting to these resource appropriation, allocation, and distribution problems. They suggest that tragedies of resource depletion and institutional failure to deal with them are not characteristic of human nature, but rather are by products of particular cultural practices, institutions, and assumptions. The detailed, empirical ethnographic study of these relationships holds great potential for informing those who are making future policy decisions as well as contributing to the theories of human behavior and cooperation to solve such problems.

The 26 recognized minor phyla comprise aberrant clades, as most of them terminate as blind offshoots. Untied from the discussion on their phylogenesis of minor phyla, this book is largely devoted, for the first time, to aspects of reproduction and development in minor phyletics. The minor phyla are not as speciose (1,795 species/phylum) as the major phyla (157,066 species/phylum) are. The accumulation of deleterious genes causes inbreeding depression among progenies arising from parthenogenesis, clonal multiplication and selfing hermaphrodites. The reason for the limited species diversity in minor phyla is traced to (i) eutelism in 65.7% of minor phyletics and (ii) existence of 21.6% clonals, (iii) 6.4% parthenogens and (iv) 1.2% selfing hermaphroditism. Gonochorism obligately requires motility to search for a mate. The combination of low motility and gonochorism from Placozoa to hemocoelomatic minor phyla has limited diversity to < 1,000 species. Over 19% of minor phyletics are hermaphrodites. With the need to manifest and maintain dual sexuality, fecundity of hermaphrodites may be reduced to 50% of that in gonochores. Adopting an array of strategies, < 100 hermaphrodites are selfers. In eutelics, mitotic division is ceased in somatic cells after hatching. For the first time, the prevalence of eutelism has been brought to light in numbers of all the six pseudocoelomate phyla and priapulids. Eutelism limits fecundity to 30-300 eggs in free-living pseudocoelomates, priapulids and possibly other hemocoelomates. In them, sperm production is less than that of egg production; as a result, a large fraction of their eggs is sterile. With a high proportion of non-eutelic gametic cells (35%), Nematoda and possibly Nematomorpha and Acanthocephala are more fecund than rotifers, in which the proportion is 15%. Briefly, the reasons for the limited species diversity in minor phyletics are traced to eutelism, parthenogenesis and clonal multiplication. Surprisingly, parthenogenesis and clonal multiplication mutually eliminate each other. This is also true of hermaphroditism and parthenogenesis. However, clonal multiplication is prevalent from structurally simplest Placozoa to the most complex Ascidiacea, except in pseudocoelomates and hemocoelomates. A limited number of cells and cell types, and the consequent structural simplicity facilitate manifestation of parthenogenesis in pseudocoelomates and parasitism in Mesozoa, Myxozoa, 59% of Nematoda, Nematomorpha, Acanthocephala and Pentastomida. Despite hermaphroditism, Bryozoa (5,700 species) and Ascidiacea (3,000 species) are speciose among minor phyla. For the first time, the importance of fusion of fragments or colonies - an event equivalent to gamete fusion at fertilization - is recognized as a source of new gene combination. Besides, the colonies in these minor phyla degenerate and regenerate more or less regularly. Only the fittest degenerated colonies may be rejuvenated and regenerated.
