Samples from two closely placed localities in western Yukon Territory have yielded late Early Devonian conodonts characteristic of areas farther to the north and east in Alaska and Yukon Territory and also characteristic of central and northern Siberia. Conodonts from a nearby locality in east-central Alaska indicate an age that makes the associated graptolites of considerable interest: they are among the youngest graptolites known in North America.

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 communities that are present. Fire and man-made disturbances initiate succession. There are 45 new reports for the District of Mackenzie and 30 for the Yukon. Of the taxa, 86% are found in Europe, Asia, and North America, 9% are known from Asia and North America, whereas only 4% are restricted to North America. Pilophorus robustus is new to Canada. High mountains in the western part of the area, generally nonglaciated during the Wisconsinian, support a flora that contains many Arctic and Arctic–Alpine taxa. Amphi-Beringian species occur primarily in the north.

Despite the rapidly expanding knowledge of Lower Devonian brachiopod faunas of the Western Cordillera of Canada (Lenz, 1976, 1977a, 1977b, 1982; Ludvigsen, 1970; Perry, 1984; Perry and Lenz, 1978; Perry et al., 1974, 1981), equivalent data on coeval gastropod faunas from this region are non-existent; to date, no publications have appeared in which gastropods have been described. Blodgett et al. (1988, table 1) provided faunal lists for two Lower Devonian localities in Western Canada: 1) Lochkovian-Emsian age collections from the Mackenzie Mountains, Northwest Territories, collected by the late D. G. Perry as part of his Ph.D. dissertation (Perry, 1984); and 2) an early Emsian collection from the Mt. Lloyd George area, British Columbia. We are currently examining the gastropod material recovered by A. C. Lenz from his richly diverse collections in the Royal Creek area, Yukon Territory, equivalent in age to those gathered by D. G. Perry from the Mackenzie Mountains. This note is the first of several papers focused on these paleobiogeographically significant faunas, and it is our desire to ultimately make clear the character of this Early Devonian province, which appears to include strata of British Columbia, Yukon and Northwest Territories, as well as the non-accreted portion of adjacent east-central Alaska.

Baumann (1976) lists the zoogeographic range of the Nearctic “winter” stonefly genus Allocapnia as being confined to Eastern North America and the Palaearctic genus Taeniopteryx Pictet as being Amphinorth American (i.e. distributed in the east and west of the continent but not in middle). Allocapnia has never been recorded west of Ontario, in Canada, and although present in some of the east-central states of the U.S.A. (Ross and Ricker 1971) has not been collected in the north flowing Red River system. Taeniopteryx is represented on the Prairies by two species, T. parvula Banks recorded from Aweme, Manitoba and T. nivalis (Fitch) from Alberta (Ricker and Ross 1968).

AbstractThe North American representatives of seven species groups in the genus Pardosa are reviewed and are found to have the following distribution: (1) the atrata group, represented by the widespread nearctic species P. fuscula (Thorell), which may or may not be conspecific with P. atrata (Thorell) of the Palaearctic; (2) the cubana group, represented by P. cubana Bryant of the Caribbean area; (3) the ferruginea group, represented by P. beringianasp.n. from Alaska and Yukon Territory; (4) the moesta group, represented by the widespread nearctic P. moesta Banks; (5) the monticola group, represented by the holarctic P. palustris (Linnaeus); (6) the saltuaria group, represented by the holarctic P. hyperborea (Thorell) and the nearctic P. californica Keyserling; (7) the solituda group, represented by the nearctic P. solituda Levi and Levi, found only in the high Rockies.

Studies, especially in the North America, have shown a relationship between political orientation and moralfoundation. This study investigated whether moral judgements differ from the political orientation of participantsin South Africa moral judgment and the extent to which moral foundations are influenced by politicalorientation.Further, the study investigated the possibility of similar patterns with the North AmericanConservative-Liberal spectrum and the moral foundation. There were 300participants, 78 males and 222 females,who completed an online questionnaire relating to moral foundation and political orientation. The results partiallysupported the hypothesis relating to Liberal and Conservative orientation in South Africa. Further, this studypartially predicted the Liberal-Conservative orientation with patterns in the moral foundation, whilst showingsimilar findings to the North American studies. A growing rate of a neutral/moderate society is evidenced in SouthAfrica and abroad, thereby showing the emergence of a more open approach to both a political and generalstance.”””
