Download or read book Reproductive Seasonality in Teleosts written by Angus D. Munro and published by CRC Press. This book was released on 2019-11-11 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: This important publication provides, for the first time, a comprehensive review of knowledge of reproductive seasonality in teleosts. It addresses why a particular species should show such seasonality, and how environmental cues act as regulators to ensure that reproductive maturation and breeding occur at the optimum time. The book considers the ultimate factors responsible for the evolution of reproductive seasonality in fish. It reviews salient concepts of reproductive seasonality in mammals. This volume also includes a review of accumulated knowledge of the control mechanisms of salmonids, gasterosteids, temperate cyprinids, cyprinodonts and other brackish-water forms, and marine and tropical freshwater teleosts. This is a work of value to research scientists in the field of environmental physiology, reproductive biology, and comparative neuroendocrinology and endocrinology. In addition, it is relevant for institutions involved with aquaculture and fisheries management. It is useful for post-graduate as well as undergraduate courses in fish biology and various related subjects.

Download or read book Fluid Preservation written by John E. Simmons and published by Rowman & Littlefield. This book was released on 2014-05-15 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluid preservation refers to specimens and objects that are preserved in fluids, most commonly alcohol and formaldehyde, but also glycerin, mineral oil, acids, glycols, and a host of other chemicals that protect the specimen from deterioration. Some of the oldest natural history specimens in the world are preserved in fluid. Despite the fact that fluid preservation has been practiced for more than 350 years, this is the only handbook that summarize all that is known about this complex and often confusing topic. Fluid Preservation: A Comprehensive Reference covers the history and techniques of fluid preservation and how to care for fluid preserved specimens in collections. More than 900 references on fluid preservation were reviewed for this project. An historical survey of preservative recipes provides for guidance for museums with older collections (many fluid preservatives contain hazardous chemicals). Current standards and best practices for collection care and management are presented. Current and controversial topics (e.g., the preservation of DNA, alternatives to alcohol and formaldehyde) are discussed and fully referenced. Health and safety issues involved with caring for fluid preserved collections are discussed. The final chapter addresses fluid preserved specimens as cultural products and their use in art, literature, film, and song. Although most fluid-preserved specimens are found in natural history and medical museums, it is not at all uncommon to find them in art museums, history museums, and science centers. In addition to animals, plants, and anatomical specimens, fluid preserved collections include some minerals and fossils and many other objects. Fluid Preservation is an essential reference for: Natural history curators Natural history collections managers Conservators Medical and anatomical museum collections managers and curators Art and history museum staff who have fluid preserved specimens and objects in their care (e.g., works by Damien Hirst) Private collectors Researchers using museum collections as sources of DNA, isotopes, etc. Health and safety professionals Exhibit planners and designers Museum facilities planners and managers People interested in the history of science People interested in the history of natural history museums Museum studies students

Download or read book Neuroendocrine Mediation of Photoperiod and Other Environmental Influences on Physiological Responses of Salmonids written by Hugh A. Poston and published by . This book was released on 1978 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Manipulation of photoperiods, combined with modifications by other environmental conditions such as temperature and salinity, can alter growth, smoltification, and sexual maturation of salmonid fishes by way of a neuroendocrine pathway. The extent of responses of salmonids to environmental changes, however, is restricted by circadian endogenous metabolic rhythms that cannot be completely overcome by external factors. The success of the manipulation of photoperiod depends primarily on four factors: the daily length and the duration of the light treatment; the season and time of day during which fish are exposed to light; the age, sex, size and species of fish; and the type of physiological response under consideration. Although gaps remain in the available information, salmonids apparently need systematically changing, intermittent periods of darkness for optimum long-term stimulation of growth, reproduction, and migration.
