The Dynamics and Use of Lacustrine Ecosystems


Book Description

Limnology is increasingly concerned with water supply and the relation of man to aquatic environments. Without the continued availability of pure water, all progress in technology and other fields of human life will be to no avail. The global problems concerning clear water are already extremely pressing. More limnology knowledge is needed to solve these problems. The responsibility of man to save water and to take more intensive care of the environment is raised in many of the papers, in this book. This emphasizes the necessary and unquestionable relevance of limnology to human society. Too often the abuse of water usage reflects the neglect of scientific results. Limnologists have a responsibility to ensure that administrators understand what is going on. The coverage of the book is wide, including papers on microbiology to engineering sciences. The biology of waters is handled at both species and ecosystem levels. The geographical distribution of topics ranges from the tropics to northern temperate areas. In fact, limnology is increasingly becoming a science which is, rightly, relevant to everyday life, not just an academic subject.

Creating Kashubia


Book Description

In recent years, over one million Canadians have claimed Polish heritage - a significant population increase since the first group of Poles came from Prussian-occupied Poland and settled in Wilno, Ontario, west of Ottawa in 1858. For over a century, descendants from this community thought of themselves as Polish, but this began to change in the 1980s due to the work of a descendant priest who emphasized the community’s origins in Poland’s Kashubia region. What resulted was the reinvention of ethnicity concurrent with a similar movement in northern Poland. Creating Kashubia chronicles more than one hundred and fifty years of history, identity, and memory and challenges the historiography of migration and settlement in the region. For decades, authors from outside Wilno, as well as community insiders, have written histories without using the other’s stores of knowledge. Joshua Blank combines primary archival material and oral history with national narratives and a rich secondary literature to reimagine the period. He examines the socio-political and religious forces in Prussia, delves into the world of emigrant recruitment, and analyzes the trans-Atlantic voyage. In doing so, Blank challenges old narratives and traces the refashioning of the community’s ethnic identity from Polish to Kashubian. An illuminating study, Creating Kashubia shows how changing identities and the politics of ethnic memory are locally situated yet transnationally influenced.
