A Science On The Scales
''A Science on the Scales: The Rise of Canadian Atlantic Fisheries Biology, 1898-1939'' is a 2011 book by Jennifer Hubbard. The book provides an analysis of Canadian fisheries history with the tools of the professional historian, when most earlier works on the topic came from fisheries scientists themselves. The book traces the development of fisheries science in Canada in the first decades of the twentieth century. Fisheries biology arose in the mid-1800s in Northern Europe from concerns around the conservation of what appeared to be dwindling stocks in the face of new technology. Marine biological stations were established in Europe in the last decades of the nineteenth century—particularly in Naples (the Stazione Zoologica Anton Dohrn) and Plymouth—but the Canadian Department of Marine and Fisheries, established in 1892, did not see a need for one in Canada, though a floating station on board a scow was eventually set up. The book "surveys the tortuous process by which t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Daniel Pauly
Daniel Pauly is a French-born marine biologist, well known for his work in studying human impacts on global fisheries and in 2020 was the most cited fisheries scientist in the world. He is a professor and the project leader of the Sea Around Us Project at the Institute for the Oceans and Fisheries at the University of British Columbia. He also served as Director of the UBC Fisheries Centre from November 2003 to October 2008. Biography Pauly was born in Paris, France. He grew up, however, in La Chaux de Fonds, Switzerland in what was called a strange "Dickensian" childhood where he was forced to stay as a live-in servant to a new family. For the first 16 years of his life, Pauly lived an inward life as he was mixed race in an all-white town, finding solace in books/reading and model construction. At 16 he ran away and put himself through high school in Wuppertal, Germany after one year working with disabled people for a local church-run institution. His work led to a schola ...

History Of Science And Technology
The history of science and technology (HST) is a field of history that examines the understanding of the natural world (science) and the ability to manipulate it (technology) at different points in time. This academic discipline also studies the cultural, economic, and political impacts of and contexts for scientific practices. Academic study of history of science History of science is an academic discipline with an international community of specialists. Main professional organizations for this field include the History of Science Society, the British Society for the History of Science, and the European Society for the History of Science. Much of the study of the history of science has been devoted to answering questions about what science ''is'', how it ''functions'', and whether it exhibits large-scale patterns and trends.

Environmental Non-fiction Books
A biophysical environment is a biotic and abiotic surrounding of an organism or population, and consequently includes the factors that have an influence in their survival, development, and evolution. A biophysical environment can vary in scale from microscopic to global in extent. It can also be subdivided according to its attributes. Examples include the marine environment, the atmospheric environment and the terrestrial environment. The number of biophysical environments is countless, given that each living organism has its own environment. The term ''environment'' can refer to a singular global environment in relation to humanity, or a local biophysical environment, e.g. the UK's Environment Agency. Life-environment interaction All life that has survived must have adapted to the conditions of its environment. Temperature, light, humidity, soil nutrients, etc., all influence the species within an environment. However, life in turn modifies, in various forms, its condition ...

6 (six) is the natural number following 5 and preceding 7. It is a composite number and the smallest perfect number. In mathematics Six is the smallest positive integer which is neither a square number nor a prime number; it is the second smallest composite number, behind 4; its proper divisors are , and . Since 6 equals the sum of its proper divisors, it is a perfect number; 6 is the smallest of the perfect numbers. It is also the smallest Granville number, or \mathcal-perfect number. As a perfect number: *6 is related to the Mersenne prime 3, since . (The next perfect number is 28.) *6 is the only even perfect number that is not the sum of successive odd cubes. *6 is the root of the 6-aliquot tree, and is itself the aliquot sum of only one other number; the square number, . Six is the only number that is both the sum and the product of three consecutive positive numbers. Unrelated to 6's being a perfect number, a Golomb ruler of length 6 is a "perfect ruler".

Maximum Sustainable Yield And The Failure Of Fisheries Management
In mathematical analysis, the maxima and minima (the respective plurals of maximum and minimum) of a function, known collectively as extrema (the plural of extremum), are the largest and smallest value of the function, either within a given range (the ''local'' or ''relative'' extrema), or on the entire domain (the ''global'' or ''absolute'' extrema). Pierre de Fermat was one of the first mathematicians to propose a general technique, adequality, for finding the maxima and minima of functions. As defined in set theory, the maximum and minimum of a set are the greatest and least elements in the set, respectively. Unbounded infinite sets, such as the set of real numbers, have no minimum or maximum. Definition A real-valued function ''f'' defined on a domain ''X'' has a global (or absolute) maximum point at ''x''∗, if for all ''x'' in ''X''. Similarly, the function has a global (or absolute) minimum point at ''x''∗, if for all ''x'' in ''X''. The value of the function at a ...

Shifting Baseline
A shifting baseline (also known as a sliding baseline) is a type of change to how a system is measured, usually against previous reference points (baselines), which themselves may represent significant changes from an even earlier state of the system. The concept arose in landscape architect Ian McHarg's 1969 manifesto ''Design With Nature'' in which the modern landscape is compared to that on which ancient people once lived. The concept was then considered by the fisheries scientist Daniel Pauly in his paper "Anecdotes and the shifting baseline syndrome of fisheries". Pauly developed the concept in reference to fisheries management where fisheries scientists sometimes fail to identify the correct " baseline" population size (e.g. how abundant a fish species population was ''before'' human exploitation) and thus work with a ''shifted baseline''. He describes the way that radically depleted fisheries were evaluated by experts who used the state of the fishery at the start of the ...

Collapse Of The Atlantic Northwest Cod Fishery
In 1992, Northern Cod populations fell to 1% of historical levels, due in large part to decades of overfishing. The Canadian Federal Minister of Fisheries and Oceans, John Crosbie, declared a moratorium on the Northern Cod fishery, which for the preceding 500 years had primarily shaped the lives and communities of Canada's eastern coast. A significant factor contributing to the depletion of the cod stocks off Newfoundland's shores was the introduction of equipment and technology that increased landed fish volume. From the 1950s onwards, new technology allowed fishers to trawl a larger area, fish more in-depth, and for a longer time. By the 1960s, powerful trawlers equipped with radar, electronic navigation systems, and sonar allowed crews to pursue fish with unparalleled success, and Canadian catches peaked in the late-1970s and early-1980s. Cod stocks were depleted at a faster rate than could be replenished. The trawlers also caught enormous amounts of non-commercial fis ...

Environmental History
Environmental history is the study of human interaction with the natural world over time, emphasising the active role nature plays in influencing human affairs and vice versa. Environmental history first emerged in the United States out of the environmental movement of the 1960s and 1970s, and much of its impetus still stems from present-day global environmental concerns. The field was founded on conservation issues but has broadened in scope to include more general social and scientific history and may deal with cities, population or sustainable development. As all history occurs in the natural world, environmental history tends to focus on particular time-scales, geographic regions, or key themes. It is also a strongly multidisciplinary subject that draws widely on both the humanities and natural science. The subject matter of environmental history can be divided into three main components. The first, nature itself and its change over time, includes the physical impact of h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
