The Prairies Ecozone of southern Manitoba, Saskatchewan, and Alberta supports a diverse fauna, with 2,232 species of butterflies and moths (order Lepidoptera) recorded to date in 61 families. By far the best known Lepidoptera are the butterflies, with 177 species known to occur in the ecozone. The species known to occur in the Prairies Ecozone are...
The distribution and general ecology of 249 macrolichen taxa is described for 230 000 km2 of coniferous forest, open fens, and alpine terrain along the Mackenzie River in the District of Mackenzie, Northwest Territories, and the Peel River, a major tributary which rises in the Yukon Territory. Permafrost plays a major role in determining the plant...
A sequel to earlier papers on bryophytes and macrolichens, this treatment describes the distribution and general ecology of 314 microlichen taxa for 230 000 km2 of coniferous forest, open fens, and alpine terrain along the Mackenzie River in the District of Mackenzie, Northwest Territories, and the Peel River, a major tributary which extends into t...
A survey of the literature combined with field studies and the reexamination of many historical collections reveals that the hepatic flora of Alberta is composed of 114 taxa, consisting of 26 families and 46 genera. Two species. Gymnomitrion corallioides and Scapania mucronata, are reported as new to the province. Two species are excluded from the...
Forty-two species of the genera Cladonia and Baeomyces in the lichen family Cladoniaceae are reported from a 13 400 km2 area in the mountains and foothills of southwestern Alberta. Thirteen of the species are new to Alberta. The distribution and habitats occupied by each of the species are described. The following North American distribution elemen...
Forty-eight species and two varieties of the genera Cetraria, Hypogymnia, Parmelia, Parmeliopsis, and Platismatia in the lichen family Parmeliaceae are reported from a 13 400-km2 area in the mountains and foothills of southwestern Alberta. Twelve of these taxa are new to Alberta. The distribution and habitats occupied by each of the taxa are descri...
Eleven species of the genera Omphalodiscus and Umbilicaria in the lichen family Umbilicariaceae are reported from a 13 400-km2 area in the mountains and foothills of southwestern Alberta. Previous reports of Umbilicaria arctica and U. cylindrica are, or are felt to be, in error. Umbilicaria cinereorufescens is reported as new to Alberta. The distri...
The relative abundance and ecology of 123 lichens, 12 liverworts, 1 peat moss, 59 mosses, and 40 vascular plants are described from the southeastern part of Prince Patrick Island, 76° N latitude. One hundred and three of the lichens, 25 of the bryophytes, and 6 of the vascular plants are first reports for the island. One lichen, Blastenia arctica,...
Bryophyte and associated macro-subfossils were recovered from a kettle located in prairie southwest of Moose Jaw in the Missouri Coteau of southern Saskatchewan. The higher plants were discussed in an earlier paper.Three samples taken from the organic layer gave C14 datings ranging from 11,650 ± 150 to 10,270 ± 150 B.P.Sixteen species and one varie...
One hundred and fifty-four taxa of bryophytes, including 15 hepatics, 2 peat mosses, and 137 mosses, are reported for the 255 000 km2 aspen parkland region of west-central Canada. Descriptions of the habitats and distribution of the individual taxa are given as well as species groups characteristic of the major habitat types. The following distribu...
Twenty-two families, 37 genera, and 82 species of Hepaticae are reported from a 13 400 km2 area in the mountains and foothills of southwestern Alberta. The distribution and habitats occupied by each of the species are described. The following distributional elements are represented: Arctic–Boreal, 43%; Pan North American, 33%; Boreal, 20%; Eastern...
A total of 83 taxa of Musci are enumerated from the prairies of Alberta, Saskatchewan, and Manitoba. These are composed of 36 soil-dwelling species, 21 that occur on rotting vegetation, 8 aquatics, 6 rupestral, and 3 corticolous. A large number of new provincial records are reported as well as the species Mnium arizonicum, new to Canada. None of th...
Fifty-seven species of microlepidoptera are reported as new for the Province of Alberta, based primarily on specimens in the Northern Forestry Research Collection of the Canadian Forest Service, the University of Alberta Strickland Museum, the Canadian National Collection of Insects, Arachnids, and Nematodes, and the personal collections of the fir...
Following the action taken by Brown (1968), Ferris (1977) in his recent revision of
Epidemia dorcas
(Kirby) and
E. helloides
(Boisduval) cited the type locality for
E. dorcas florus
(W. H. Edwards) as “ ‘Taken on Red Deer River B. Am., by Captain Geddes’ — later restricted by Edwards to ‘Garrett's Ranche, Br. Amer.’; actually Didsbury, just north o...
The distribution and general ecology of 263 bryophyte taxa are presented for an extensive area of coniferous forest, open fens, and alpine terrain along the Mackenzie River in the District of Mackenzie and the Peel River, a major tributary which extends into the Yukon. The continuous or discontinuous permafrost which underlies the area plays a majo...
Many of the place names used by Thomas Drummond (d. 1835) in his narratives and exsiccati series are obscure, misleading, or no longer current. His route of exploration through western Canada is traced. The mosses that he reported are listed with the nomenclature and locality names brought up-to-date.
