Autor: J. C. Kingston, Allen J. Uutala, Harry John Betteley Birks, John P. Smol, Keith E. Camburn, Sushil S. Dixit, Donald F. Charles, A. R. Selle, Brian F. Cumming
Publikováno v: Canadian Journal of Fisheries and Aquatic Sciences. 49:128-141
Preindustrial and present-day lake water pH, acid neutralizing capacity (ANC), total monomeric aluminum (Alm), and dissolved organic carbon (DOC) were inferred from the species composition of diatom and chrysophyte microfossils in the tops (present-d

McNearney Lake is an acidic (pH=4.4) lake in the Upper Peninsula of Michigan with low acid neutralizing capacity (ANC=-38 μeq L-1) and high SO inf4 sup2- and aluminium concentrations. Oligotrophy is indicated by high Secchi transparency and by low c

Publikováno v: Journal of Paleolimnology. 4:153-201
Paleoecological analyses of sediments from nine northern Great Lakes states (NGLS) lakes reveal small pH changes in seven of these lakes since 1860, four of these being declines. The largest diatom-inferred (DI) pH declines of 0.5 pH units were found

An ultrastructural study of pyrenoids inLeptosiropsis torulosa
Autor: Daniel E. Wujek, Keith E. Camburn, Hollings T. Andrews
Publikováno v: Protoplasma. 86:263-268
The ultrastructure of the mature pyrenoid of the chaetophoracean algaLeptosiropsis torulosa is unlike any described for the green algae. The nucleus is surrounded by the pyrenoid, with only the endoplasmic reticulum interrupting the encircling pyreno

Epizoic occurrence of Compsopogon coeruleus (Rhodophyta) on Lernaea (Copepoda) from Kentucky fishes
Autor: Melvin L. Warren, Keith E. Camburn
Publikováno v: Canadian Journal of Botany. 61:3545-3548
The freshwater red alga Compsopogon coeruleus (Balbis) Montagne occurred epizoically on the parasitic copepod genus Lernaea from fishes (Osteichthyes, Cyprinidae) collected from the Mud River, Butler County, Kentucky. Twelve specimens of Lernaea spp.
