Excerpt from Freshwater Isopods (Asellidae) Of North America: For the Environmental Protection Agency, May 1972Specimens are best killed and preserved by directly placing them in 70 80% ethyl alcohol. Transference to fresh alcohol after a few days is re commended. Care should be exercised to ensure that crowding of preserved specimens does not occur, and that tubes are adequately labelled. The maintenance of live specimens is not required for ...

Aquatic entomology has undergone major advances in recent times. For example, aquatic insects are now routinely used to test hypotheses in contemporary ecological theory and to model predictive changes resulting from climate change. Research has also revealed the importance of aquatic insects in the spread of diseases, in the biological assessment of water quality, and in the reconstruction of past environments on earth. Further, it is now acc...

Australia is the world's driest inhabited continent. Water is our limiting resource. It might therefore be thought that our water resources would be the subject of the most intensive study. Certain aspects, it must be conceded, have received much attention, notably the availability of water in terms of actual quantity. The size of the surface water and the groundwater resource is well understood and indeed receives about as much study as can r...

This publication is composed of papers presented at an International Symposium on Athalassic (Inland) Salt Lakes, which was hosted by the University of Adelaide, South Australia, during a week in October 1979. The genesis of the Symposium was at the Copenhagen Congress of the International Association of Limnology (S.1. L.) where it was noted that a number of papers concerned with inland saline lakes were distributed throughout sessions in suc...

This is a pre-1923 historical reproduction that was curated for quality. Quality assurance was conducted on each of these books in an attempt to remove books with imperfections introduced by the digitization process. Though we have made best efforts - the books may have occasional errors that do not impede the reading experience. We believe this work is culturally important and have elected to bring the book back into print as part of our cont...

components dissolve. The alumino silicate minerals are the great example of the incongruent class, releasing Na+, K+, HCO-, etc. ions in reaction with J water but retaining most of their atoms in re-ordered solids such as kaolinite. The karst minerals are all congruent in normal conditions. Incongruent solution of dolomite and precipitation of calcite may occur in some exceptional conditions mentioned later. The sample of congruent minerals in...
