In 1982-84, a number of specimens of V. fulleri were found in the lower Mississippi River and in an adjacent oxbow lake (Eagle Lake), about 19 river kilometers northwest of Vicksburg, Mississippi. In the lake, the species was collected in the inshore 1-m depth zone but not at 1.6-m depths offshore, where the waters stratified thermally in July and August and the dissolved oxygen concentration sometimes fell to 0.5 mg/liter in the hypolimnion.. The collection of sexually mature worms in the river in May 1982 and in Eagle Lake in January-February 1984 enabled us to describe anatomical details that refine the description of the species.","PeriodicalId":154110,"journal":{"name":"Freshwater Invertebrate Biology","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1985-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132616798","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Distributional, architectural and experimental data were examined to determine the role of the helical case in the microdistribution of this species. Both crushing resistance and hydrodynamics were probable selection pressures in the evolution of the coiled case architecture. This evolution probably took place in open-canopied streams where H. borealis larvae were grazers on periphyton-covered rock surfaces. In this habitat, the spiral shape of the case prevented larvae from being crushed during spates. Hydrodynamic aspects of the case shape allowed the larvae grazing access on surfaces exposed to current.","PeriodicalId":154110,"journal":{"name":"Freshwater Invertebrate Biology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1985-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128582242","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Placer mining caused increased turbidity, and increased amounts of settleable solids, and suspended sediment (nonfilterable residues). Sediment from placer mining was associated with decreased density and biomass of invertebrates. In a stream where mining began in mid-August, Orthocladiini (Diptera: Chironomidae) and Chloroperlid stoneflies decreased in abundance while they were not decreased in a nearby unmined stream. Water mites seemed to be the organisms most affected by placer mining.","PeriodicalId":154110,"journal":{"name":"Freshwater Invertebrate Biology","volume":"344 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1985-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122546253","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There was less seasonality in abiotic factors, particularly in discharge and temperature below the impoundment. The streambed below the reservoir was more heterogenous and more stable than that above. Macroinvertebrate density was almost five times greater below the reservoir as a result of enhanced temperature and flow constancy, greater substrate stability and the abundance of aquatic macrophytes at this site. Species richness was also greater below the impoundment and was directly related to its habitat heterogeneity. Reduced discharge and more constant temperatures in conjunction with extremely high macroinvertebrate densities resulted in reduced diversity below the impoundment. Evenness was also reduced. An analysis of seasonal evenness variances and a study of the seasonal abundance patterns of individual taxa indicated that the more constant physicochemical conditions below the reservoir probably decreased biotic interactions and reduced the community stability at this site.","PeriodicalId":154110,"journal":{"name":"Freshwater Invertebrate Biology","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1985-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124194950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
