Donald Strathearn Rawson
Donald Strathearn Rawson (19 May 1905 – 16 February 1961) was a Canadian limnologist who worked with the University of Saskatchewan from 1928 to 1961. For his research, Rawson wrote six publications about twelve lakes he had researched in Saskatchewan. He additionally conducted lake investigations in Western Canada during the 1930s and the Northwest Territories in the 1940s. While with the university, Rawson was both in charge of their Fisheries Laboratory and head of biology from the late 1940s to early 1960s. In 1944, Rawson was a Fellow of the Royal Society of Canada. For Canada, Rawson was posthumously named a Person of National Historic Significance in 2019. Early life and education On 19 May 1905, Rawson was born in Claremont, Ontario.

Limnologist
Limnology ( ; from Greek λίμνη, ''limne'', "lake" and λόγος, ''logos'', "knowledge") is the study of inland aquatic ecosystems. The study of limnology includes aspects of the biological, chemical, physical, and geological characteristics of fresh and saline, natural and man-made bodies of water. This includes the study of lakes, reservoirs, ponds, rivers, springs, streams, wetlands, and groundwater.Wetzel, R.G. 2001. Limnology: Lake and River Ecosystems, 3rd ed. Academic Press () Water systems are often categorized as either running (lotic) or standing (lentic). Limnology includes the study of the drainage basin, movement of water through the basin and biogeochemical changes that occur en route. A more recent sub-discipline of limnology, termed landscape limnology, studies, manages, and seeks to conserve these ecosystems using a landscape perspective, by explicitly examining connections between an aquatic ecosystem and its drainage basin. Recently, the need to understa ...

Lake Athabaska
Lake Athabasca (; French: ''lac Athabasca''; from Woods Cree: , "herethere are plants one after another") is located in the north-west corner of Saskatchewan and the north-east corner of Alberta between 58° and 60° N in Canada. The lake is 26% in Alberta and 74% in Saskatchewan. History The name in the Dene language originally referred only to the large delta formed by the confluence of the Athabasca River at the southwest corner of the lake. Prior to 1789, Sir Alexander Mackenzie explored the lake. In 1791, Philip Turnor, cartographer for the Hudson’s Bay Company, wrote in his journal, "low swampy ground on the South side with a few willows growing upon it, from which the Lake in general takes its name Athapison in the Southern Cree tongue which signifies open country such as lakes with willows and grass growing about them". Peter Fidler originally recorded the name for the river in 1790 as ''the Great Arabuska''. By 1801, the name had gained a closer spelling to the ...

Academic Staff Of The University Of Saskatchewan
An academy (Attic Greek: Ἀκαδήμεια; Koine Greek Ἀκαδημία) is an institution of secondary or tertiary higher learning (and generally also research or honorary membership). The name traces back to Plato's school of philosophy, founded approximately 385 BC at Akademia, a sanctuary of Athena, the goddess of wisdom and skill, north of Athens, Greece. Etymology The word comes from the ''Academy'' in ancient Greece, which derives from the Athenian hero, ''Akademos''. Outside the city walls of Athens, the gymnasium was made famous by Plato as a center of learning. The sacred space, dedicated to the goddess of wisdom, Athena, had formerly been an olive grove, hence the expression "the groves of Academe". In these gardens, the philosopher Plato conversed with followers. Plato developed his sessions into a method of teaching philosophy and in 387 BC, established what is known today as the Old Academy. By extension, ''academia'' has come to mean the accumulation, dev ...

Canadian Limnologists
Canadians (french: Canadiens) are people identified with the country of Canada. This connection may be residential, legal, historical or cultural. For most Canadians, many (or all) of these connections exist and are collectively the source of their being ''Canadian''. Canada is a multilingual and multicultural society home to people of groups of many different ethnic, religious, and national origins, with the majority of the population made up of Old World immigrants and their descendants. Following the initial period of French and then the much larger British colonization, different waves (or peaks) of immigration and settlement of non-indigenous peoples took place over the course of nearly two centuries and continue today. Elements of Indigenous, French, British, and more recent immigrant customs, languages, and religions have combined to form the culture of Canada, and thus a Canadian identity. Canada has also been strongly influenced by its linguistic, geographic, and ...

Ostracodes
Ostracods, or ostracodes, are a class of the Crustacea (class Ostracoda), sometimes known as seed shrimp. Some 70,000 species (only 13,000 of which are extant) have been identified, grouped into several orders. They are small crustaceans, typically around in size, but varying from in the case of ''Gigantocypris''. Their bodies are flattened from side to side and protected by a bivalve-like, chitinous or calcareous valve or "shell". The hinge of the two valves is in the upper (dorsal) region of the body. Ostracods are grouped together based on gross morphology. While early work indicated the group may not be monophyletic and early molecular phylogeny was ambiguous on this front, recent combined analyses of molecular and morphological data found support for monophyly in analyses with broadest taxon sampling. Ecologically, marine ostracods can be part of the zooplankton or (most commonly) are part of the benthos, living on or inside the upper layer of the sea floor. While Myodoco ...
