History of Ecological Sciences, Part 49: Formalizing Animal Ecology, 1870s to 1920s

History of Ecological Sciences, Part 63: Biosphere Ecology

“…Cohen had Camerano's food web article translated into English (Camerano ). Camerano's two food web diagrams are like none published later (Egerton ,b:62–63), indicating that they had little influence. They nevertheless indicate progress in the study of food webs.…”

“…One question raised was “Does not the rebirth of seed from earth and water and its growth into plants for the use of man sufficiently demonstrate the workings of the providence of God?” (translated in Howe :409). One son responded: “When they are sown, the earth, by the divine will, pours out upon these seeds the water it has received…” (in Howe :410; Egerton ,b:208). The son then proposed seeds be planted in a known weight of dirt, with nothing added but water.…”

History of Ecological Sciences, Part 62: Saving Habitats and Managing Wildlife in the United States and Canada before 2000

“…The Federal Government developed roles for agencies in the Departments of Agriculture, Commerce, and Interior (Dingell and Potter ). C. Hart Merriam (1855–1942), whom we met in parts 49 and 61B (Egerton :65–69, :33–34), was more interested in birds and mammals than in practicing medicine. In 1884, AOU asked Congress to establish an office to study birds and mammals (Dunlap :35).…”

History of Ecological Sciences, Part 54: Succession, Community, and Continuum

“…German botanist (Carl George) Oscar Drude (1852Drude ( -1933 studied under Grisebach at Göettingen and received his doctorate in 1873 (Egerton 2013:345-346 Drude's text for German plant geography provided guidance for these plant geographers on the Nebraska prairie, Clements and Pound (Egerton 2013:358-360), though Tobey's characterization of their work as quantified is an exaggeration (Nicolson 1988:194 Plant ecology, animal ecology, limnology, and marine ecology during the later 1800s developed independently (Egerton 2013(Egerton , 2014a, yet there were some parallels. Developments in animal ecology and marine ecology during that time had parallels with plant ecology.…”

“…In more recent terminology, one could call a lake an ecosystem. Logically, his talk was a contribution to limnology, but in reality François Forel was developing limnology simultaneously in Switzerland with no awareness of Forbes, and therefore Forbes' 1880 and 1887 contributions were to general ecology, not directly to limnology (Egerton 2014a(Egerton :64-66, 2014b). …”
