Download or read book The Freshwater Ecosystems of Suriname written by P.E. Ouboter and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the limnological research on the man-made Brokopondo Reservoir in the 'sixties, numerous data have been collected on the ecology of Surinam rivers and swamps. This book is a compilation of these data: it is the first comprehensive survey of the aquatic ecology of one of the peripheral areas of Amazonia. The geomorphology of the country, situated on the Guyana Shield, is the main factor determining the limnological properties of rivers and creeks. This results in an overall picture that is quite different from Amazonia. The emphasis of The Ecosystems of Suriname is on the living aquatic resources, including aquatic and swamp vegetation, phyto and zooplankton, macroinvertebrates, fish, amphibians, reptiles and mammals. Although most of Suriname is still in a pristine state, the human impact on fresh waters is considerable in those areas of rapid economic development, emphasizing the necessity of conservation measures, specially tailored for aquatic ecosystems. The Ecosystems of Suriname is a valuable acquisition for all scientists, environmental managers and others interested in tropical aquatic ecology.

Download or read book Genetics Evolution and Conservation of Neotropical Fishes written by Rodrigo A. Torres and published by Frontiers Media SA. This book was released on 2020-01-21 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fish represent the most ancestral and specious group of vertebrates, and occupy more diverse aquatic environments around the world. Ichthyofauna is extremely diverse, especially in megadiverse countries occupying biogeographical regions such as the Neotropical Region, which covers an extensive area between North and South America. Much of this biodiversity will be extinct, even before science knows any aspect of its biology. Like this, Neotropical fish genetics started in the end of the 70’s with papers studying the chromosomes of Hoplias malabaricus (Family Erythrinidae) and the karyotype variation among three genera of the family Anostomidae. The topic at that time was concentrated in two Institutions from the state of São Paulo, Southeastern Brazil. In the middle 80’s, the first Symposium on Neotropical Fish Cytogenetics was organized. Nowadays, the field of Neotropical Fish Genetics is present in Brazil, Colombia, Argentina, Uruguai, Venezula, Chile, and Equador, as well as outside South America in Panama, Mexico, USA, Canada, Czech Republic, Germany, and Spain. The research developed in cytogenetics has focused mainly on karyotype evolution and cytotaxonomy, chromosome structure and, more recently, cytogenomics. In relation to the use of molecular markers, support has been sought for the management of populations for conservation or production in captivity. In addition, many studies have been carried out with the aim of establishing supra-specific phylogenetic relationships and clarifying species distribution scenarios by phylogeographic modeling. The genome and transcriptome of some model species begin to emerge as extremely promising and informative areas for neotropical fish. In 2017, the Neotropical fish genetics research community celebrates the 30th anniversary of its main Meeting (today entitled Symposium on Neotropical Fish Genetics and Cytogenetics). This Research Topic is part of this celebration and aims at reporting the state of the art and its current advances in the frontier of knowledge in genetics, evolution, and conservation of neotropical fish, as well as to detect the challenges to be overcome in the next years.

Download or read book The Basics of Aquarium and Tropical Fish Care written by Dennis Wildberger and published by DocWild Publishing Company. This book was released on 2019-04-18 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquariums have become a hot item. The world has become polluted, so many people are starting to appreciate the beauty of nature. This means that more people are attempting to bring nature and its natural beauty into their homes. Aquariums and fish care processes today make it easy, because technology has combined technical, electrical, and natural resources to pool aquariums together. This includes switches, controls, etc., and these features enable aquarium users to do less and have more. These new changes have also brought on the need to research information to help aquarists learn how to maintain fish tanks and learn fish care. With this in mind, we have compiled all information needed and related to fish care and aquariums. In this book, you will learn the types of fish, aquariums, care, filters, and more.

Download or read book The Freshwater Fishes of Suriname written by Jan H.A. Mol and published by BRILL. This book was released on 2012-09-19 with total page 899 pages. Available in PDF, EPUB and Kindle. Book excerpt: With some 480 currently known fresh- and brackish-water fish species, Suriname has a rich inland fish fauna that is related to the most diverse freshwater fish fauna on planet Earth, i.e. that of the Amazon River. Interest in the freshwater fishes of Suriname by naturalists and scientists extends back over more than two centuries. Suriname is undoubtedly the site of origin of the oldest extant preserved specimens of South American fishes and 19 Surinamese fish species were described and figured by Linnaeus. Building on ichthyological studies initiated in the 1960s by the Brokopondo Project, this book provides an introduction to the freshwater fish fauna of Suriname, including identification keys, photographs of the species and descriptions of their habitats, that should be especially useful to decision makers, conservation biologists, aquarium hobbyists and eco-tourists.

Download or read book Man Fishes and the Amazon written by Nigel J. H. Smith and published by Columbia University Press. This book was released on 1981 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: Few aspects of American military history have been as vigorously debated as Harry Truman's decision to use atomic bombs against Japan. In this carefully crafted volume, Michael Kort describes the wartime circumstances and thinking that form the context for the decision to use these weapons, surveys the major debates related to that decision, and provides a comprehensive collection of key primary source documents that illuminate the behavior of the United States and Japan during the closing days of World War II. Kort opens with a summary of the debate over Hiroshima as it has evolved since 1945. He then provides a historical overview of thye events in question, beginning with the decision and program to build the atomic bomb. Detailing the sequence of events leading to Japan's surrender, he revisits the decisive battles of the Pacific War and the motivations of American and Japanese leaders. Finally, Kort examines ten key issues in the discussion of Hiroshima and guides readers to relevant primary source documents, scholarly books, and articles.

Book excerpt: The current world biodiversity consists of an inestimable amount of living forms, that at all levels, from genes to biomes, from individuals to populations, from species to communities, are in constant pursuit of the best strategies to react to the natural and anthropic environmental changes. The arrangement of new and dynamic ecosystems balanced by the formation and the vanishing of species, is the direct consequence of these changes. This book contains comprehensive overviews and original studies focused on ecological and ecosystem functioning studies, hazards and conservation management, assessment of environmental variables affecting species diversity, also considering species richness and distribution, in order to identify the best management strategies to face and solve the conservation problems.

Download or read book Evolution in the Dark written by Horst Wilkens and published by Springer. This book was released on 2017-05-25 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides fascinating insights into the development and genetics of evolutionary processes on the basis of animals living in the dark, such as the Astyanax cave fish. Biologically functionless traits show high variability, which results from neutral deleterious mutations no longer being eliminated by natural selection, which normally acts to preserve functional capability. These negative mutations accumulate until the traits they are responsible for become rudimentary or even lost. The random genetic basis of regressive evolution is in accordance with Nei’s Neutral Theory of Molecular Evolution, which applies to the molecular level. Such processes are particularly conspicuous in species living in constant darkness, where, for example in Astyanax, all traits depending on the exposure to light, like eyes, pigmentation, visually triggered aggressive behaviour, negative phototaxis, and several peripheral outcomes of circadian rhythmicity, are useless and diminish. In compensation constructive traits like taste, olfaction or the lateral line senses are improved by selection and do not show variability. Regressive and constructive traits inherit independently, proving that the rudimentation process is not driven by pleiotropic linkage between them. All these traits are subject to mosaic evolution and exhibit unproportional epistatic gene effects, which play an important role in evolutionary adaptation and improvement. Offering valuable evolutionary insights and supplemented by a wealth of illustrations, this book will appeal to evolutionary and developmental biologists alike.
