Studies of Birds and Mammals in the Baird and Schwatka Mountains, Alaska

In 1963 a joint University of Alaska-Smithsonian Institution crew worked at five locations in the Baird and Schwatka mountains in northwestern Alaska, conducting an ecological reconnaissance and faunal and floral inventory. Standard methods of observation and collection were used. Camps in the Kobuk drainage were located in the Redstone River valley and at Walker Lake, both on the margin of the taiga. The Noatak valley was represented by one camp each in the lower, middle, and upper reaches of the river, all in tundra. A summary of pre-1963 ornithological work in the region is presented. Significant records of distribution and/or breeding were obtained for the following birds: Podiceps grisegena, Anas platyrhynchos, Aythya valisineria, Histrionicus histrionicus, Melanitta perspicillata, Mergus merganser, Aphrizia virgata, Bartramia longicauda, Actitis macularia, Tringa flavipes, Phalaropus fuficarius, Lobipes lobatus, Larus hyperboreus,Xema sabini, Sayornis saya, Nuttalornis borealis, Eremophilia alpestris, Tachycineta thalassina, Riparia riparia, Petrochelidon pyrrhonota, Phylloscopus borealis, Dendroica petechia, Leucosticte tephrocotis, Zonotrichia atricapilla, Calcarius pictus; and the mammal, Spermophilus undulatus. Good series of Cletihrionomys rutilius (350) and Microtus miurus (147) have been deposited in the University of Alaska Museum. Severe doubt has been raised regarding the validity of the standard three-night trap grid for population estimation under wet conditions in arctic areas

The Intersection of American Nativism and Eugenics: Anti-Japanese Sentiment Prior to World War II

This thesis examines how the anti-Japanese sentiment and legislation promoted by those leading the American eugenics movement contributed to the key economic, diplomatic, and social policies that influenced the start of the Pacific War. In the years leading up to and following World War I, Japan desired and sought full parity, including diplomatic racial equality, with the United States and other Anglo-Saxon powers. However, the United States wanted to maintain the pre- and post-World War I world order, which meant the continued subordination of Japan on the world stage. As both nations sought global economic expansion and colonialism in the Far East, the attitudes and behaviors of both nations eventually thrust them into war. The rise of American racial prejudice embodied in the theories of scientific racism, most notably the ideology of eugenics, led to anti-Japanese sentiment from the turn of the twentieth century on and influenced the relationship between the two nations. Whatever potential reconciliation efforts existed with Japan expired with the passage of the Immigration Act of 1924 (Johnson-Reed Act). Several high-ranking Japanese diplomats and military officials believed that if nations outside the US did not attain racial equality, then the next war would be along the color line. Thus, this hostility intensified up to the attack on Pearl Harbor. This thesis addresses how Madison Grant, and his exclusionists utilized the eugenics movement and scientific racialized ideology to influence political, economic, social, and diplomatic decision making that contributed to the dismantling of relations with Japan

Distinct patterns in alpine vegetation around dens of the Arctic fox

The arctic fox Alopex lugopus excavates its dens in gravely ridges and hillocks, and creates a local environment quite distinct from the surrounding tundra or heath landscape. In northern Sweden, the vegetation of 18 dens of the arctic fox was investigated, as well as reference areas off the dens but in geologically and topographically similar locations. The species composition showed considerable differences between den and reference areas, with grasses and forbs occurring more abundantly on the dens, and evergreen dwarf-shrubs occurring more in reference areas. The effect of the foxes' activities is thought to be either through mechanical soil disturbance, or through nutrient enrichment via scats, urine, and carcasses. This was expected to result in differences in plant traits with key functional roles in resource acquisition and regeneration, when comparing dens with reference areas. We hypothesised that the community mean of specific leaf area (SLA) would differ if nutrient enrichment was the more important effect, and that seed weight, inversely proportional to seed number per ramet and hence dispersal ability, would differ if soil disturbance was the more important effect. Specific leaf area showed a significant difference, indicating nutrient enrichment to be the most important effect of the arctic fox on the vegetation on its dens. Arctic foxes act as ecosystems engineers on a small scale, maintaining niches for relatively short-lived nutrient demanding species on their dens in spite of the dominance of long-lived ericaceous dwarf-shrubs in the landscape matrix. Thus, foxes contribute to the maintenance of species richness on the landscape level
