Acidification Of Minnesota Soils By Nitrogen Fertilization And Acid Rain, Paul R. Bloom, William M. Schuh, W. W. Nelson
Acidification Of Minnesota Soils By Nitrogen Fertilization And Acid Rain, Paul R. Bloom, William M. Schuh, W. W. Nelson
Journal of the Minnesota Academy of Science
The effect of inputs of acidifying nitrogen fertilizer and acid rain on the pH of a typical Minnesota prairie agricultural soil was estimated. Experimental data from a long term continuous corn experiment at the Southwest Experiment Station near Lamberton were used to calculate the effects of nitrogen fertilizers. Acid rain effects were estimated using soil buffering data obtained in the experiment along with existing estimates of rainfall acidity. In a typical corn-soybean rotation, using 100 kg per ha of nitrogen additions to corn, a 0 .25 unit pH drop is expected in about 38 years. The estimated acidity of the …

Genetic Differentiation In Populations Of The Freshwater Amphipod Gammarus Minus Say In A Karst Area, Steven W. Hetrick, James L. Gooch
Genetic Differentiation In Populations Of The Freshwater Amphipod Gammarus Minus Say In A Karst Area, Steven W. Hetrick, James L. Gooch
International Journal of Speleology
The genetic makeup of populations in a particular geographic area should conform, in part, to environmental structure. Three polymorphic enzyme loci in the amphipod Gammarus minus are geographically differentiated in gene frequencies in the mid-Appalachian Mountains of the eastern United States, and genetic breaks usually coincide with topographical features and stream divides. Areas with well integrated drainage systems have a high degree of genetic uniformity.
Genetic Population Structure In An Amphipod Species, James L. Gooch, S. W. Golladay
Genetic Population Structure In An Amphipod Species, James L. Gooch, S. W. Golladay
International Journal of Speleology
Genetic structure of a species should conform, in part, to environmental structure. Three polymorphic enzyme loci in the amphipod Gammarus minus Say are geographically differentiated in gene frequencies in the mid-Appalachian Mountains of the eastern United States, and genetic breaks usually coincide with topographical features and stream divides. Considering alleles as migrational markers, it is expected that heterozygosity would decrease upstream in isolated drainage basins, increase in the headwaters of adjacent but oppositely flowing streams in which gene exchange was occurring between genetically differentiated populations, and increase in sites near regional master streams. These genetic patterns were found to exist …

Variation Among Populations Of The Troglobitic Amphipod Crustacean Crangonyx Antennatus Packard (Crangonyctidae) Living In Different Habitats, Iii: Population Dynamics And Stability, Gary W. Dickson, John R. Holsinger
International Journal of Speleology
Populations of the troglobitic amphipod Crangonyx antennatus from caves in Lee Co., Virginia (U.S.A.) were investigated on both a short and long term basis. The dynamics of populations living in two distinct aquatic cave habitats (mud-bottom pools and gravel-bottom streams) were compared seasonably for one year. Sex ratios indicated a larger number of females in both pool and stream habitats. The majority of males in both habitats were found to be sexually mature throughout the year investigated. Seasonal fluctuations in female maturity were observed in both habitats, with larger numbers collected in June and August. In addition, a larger number …
Some Implications Of Competition For Cave Stream Communities, David C. Culver
Some Implications Of Competition For Cave Stream Communities, David C. Culver
International Journal of Speleology
Based on recent theoretical work by Robert May and Richard Levins, two hypotheses about time fluctuations in abundance of competing species were generated. Data for isopods and amphipods from four cave stream communities in Virginia and West Virginia were used to test the predictions. First, variance of total abundance should be less than the sum of the variances of individual species’ abundances. In three of four communities studied, the prediction was confirmed, but none were statistically significant. Positive correlations among carrying capacities of competing species may explain the poor agreement with predictions. Second, the signs of 19 correlations and partial …
Distribution And Habitat Diversity Of Subterranean Amphipods In The Rocky Mountains Of Colorado, U. S. A., James V. Ward, John R. Holsinger
Distribution And Habitat Diversity Of Subterranean Amphipods In The Rocky Mountains Of Colorado, U. S. A., James V. Ward, John R. Holsinger
International Journal of Speleology
Subterranean amphipods have been collected from 35 locations on the eastern and western slopes of the Continental Divide in Colorado. All belong to the exclusively subterranean genus Stygobromus. Five species have been identified, two of which are undescribed. Specimens have been collected from (a) the hyporheic zone of rivers, (b) interrupted streams, (c) springs, and (d) seeps at elevations from 1597-2134 m a.s.l. Stygobromus occurs in several habitat types in interrupted drainage basins including sources, seeps, and isolated pools containing leaf detritus. All habitats contained waters which were cool to cold with dissolved oxygen values ranging from 4.3 ppm …
