Trianon and its aftermath: British geography and the ‘dismemberment’ of Hungary, c.1915- c.1922

In the wake of World War I, geographers helped advise national delegations at the 1919 Paris Peace Conference whose purpose was to delimit Europe’s new boundaries. The paper examines the role played by British geographers, specifically Alan Ogilvie and the British geographical delegation, in the Treaty of Trianon (1920) which greatly reduced Hungary’s territorial extent. Attention is paid to contemporary published work on the new Europe, particularly Marion Newbigin’s Aftermath: A Geographical Study of the Peace Terms and Ogilvie’s Boundary Settlement (1922). Assessment of manuscript diaries and correspondence reveals the complex circumstances faced by geographers engaged in peace work. The work of different practitioners – in the Royal Geographical Society (RGS), over how national boundaries should be arrived at (on either ethnic or physiographic grounds) – was hindered by inadequate map provision from British geographical institutions. This led Ogilvie to propose a new geographical body for Britain at a time when the RGS was facing criticism and when the meetings of the British Association for the Advancement of Science, not the RGS, provided the forum for discussion of the new post-war Europe.Csak helyi hálózaton érhető el / Restricted to LA

Studies on Lake Erie's littoral algae; Host specificity and temporal periodicity of epiphytic diatoms

Substratum specificity and temporal periodicity of the attached diatom flora upon three aquatic vascular plants and an artificial substratum were examined in three Lake Erie marshes. No qualitative or quantitative specificity for substrata was observed. Variability of diatom assemblage structure within replicate samples of a particular substratum type was as great as, or greater than, variability between substrata. Diatom assemblages upon dowel rod displayed a mid to late summer density maximum. Variability of density maxima upon natural substrata was attributed to different growth rates of the host macrophytes. Diatom assemblages within each sampling site possessed a distinct temporal periodicity indicating that factors affecting diatom growth are heterogeneous in distribution throughout Lake Erie's littoral zone.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/42923/1/10750_2004_Article_BF00013712.pd

Benthic algal response to N and P enrichment along a pH gradient

Nutrient enrichment and its effect on benthic algal growth, community composition, and average cell size was assessed across two sites of differing pH within a single habitat. Nutrients were added using in situ substrata, which released either N, P, or no additional nutrients (controls) at each site for 21 days. Upon collection, chlorophyll and biovolume standing stocks of the attached algal microflora were measured. Chlorophyll concentration was different among all treatments, accumulating greatest on P, followed by N, and the least on C substrata (P < 0.001) and was highest at site-2 (P < 0.001), while total algal biovolume was highest on P compared to both N and C substrata (P < 0.05) and did not vary between sites. Increased growth on P substrata was due to the enhanced biovolume of filamentous green algae, although the affected taxa varied between sites. Biovolume to cell density ratios (as a measure of average cell size) were highest on P substrata over both N-enriched and control substrata (P < 0.05) and this pattern was similar between sites. Progression towards a community composed of larger cells following P enrichment observed along this pH gradient, seems to be related to the dominance of larger celled filamentous green algae. Thus, nutrients exhibited greater control on benthic algal growth than did changes in hydrogen ion concentration.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/42877/1/10750_2004_Article_BF00007599.pd
