Five experiments were conducted (spring, summer and fall, 1980 and spring and fall, 1981) at three test flows (0.57, 0.28 and 0.03 m3/sec). Insect samples were taken with a modified Hess sampler and standard drift nets. Reduced stream discharge caused catastrophic drift in the test channel with drift peaking at night. Simulium sp. and Baetis tricaudatus were the principal drift components. Evidence of stranded insects in the dewatered zone was greatest in the fall, least in the spring.","PeriodicalId":154110,"journal":{"name":"Freshwater Invertebrate Biology","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1983-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124086647","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 a significant correlation for total invertebrates. The presence of fish and invertebrate predators in the activity traps, water temperature, and water depth did not affect the significance of the correlation for total invertebrates. The correlations for the two functional groups considered, herbivore-detritivores and predator-parasites, were significant. The presence of fish in the activity trap did affect the correlations for some individual taxa. There were no correlations for several taxa of predaceous invertebrates. Considering its advantages and limitations, the activity trap can be useful in many types of experimental and long-term studies of nektonic invertebrates.","PeriodicalId":154110,"journal":{"name":"Freshwater Invertebrate Biology","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1983-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128421403","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}

The following taxa reached densities within fish exclosures that were significantly higher than those in control nets on at least one occasion: Alona, Chydorus, and Eurycercus (Cladocera: Chydoridae); cyclopoid copepods; non-predaceous midges (Chironominae and Orthocladinae) and predaceous midges (Ceratopogonidae and Tanypodinae). Evidence for the direct effect of fish predation on prey densities was most convincing for Chydorus during their \"spring crash\" in early April, Eurycercus during a less dramatic decline in late April to early May, and for non-predaceous midges after three months of fish exclusion in mid-June. Each of these taxa was an important component of the diet of small bluegill sunfish during the relevant time periods.","PeriodicalId":154110,"journal":{"name":"Freshwater Invertebrate Biology","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1983-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121588595","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}

These morphological variables were related to four buffer variables of water using a canonical correlation analysis. Results showed that the main effect of a decrease in buffering capability and an increase in noncarbonate anion content is a short but heavily calcified shell in Amnicola limosa, Valvata tricarinata, Campeloma decisum, Pisidium casertanum, Pisidium variabile, Sphaerium simile, Sphaerium striatinum and Anodonta grandis grandis. Waters with increasing buffering capability relative to calcium hardness result in short, heavily calcified shells in Elliptio complanata and longer shells with increases in tissue calcium relative to weight in Helisoma anceps and Musculium secris. The latter effect is also found in Pisidium compressum but increasing calcium concentration is more important. Short shells with decreasing calcium content relative to weight is related to decreasing calcium bicarbonate alkalinity relative to total hardness for Physella gyrina but to increases in these buffer variables for Cincinnatia cincinnatiensis. All species except E. complanata showed more than one significant canonical variate suggesting that acidic deposition would not be a factor in the disappearance of any species from water with pH > 5.50.","PeriodicalId":154110,"journal":{"name":"Freshwater Invertebrate Biology","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1983-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116728142","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}

Chadwick","doi":"10.2307/1467172","DOIUrl":"https://doi.org/10.2307/1467172","url":null,"abstract":"A 46 km section of the Dolores River, in southwest Colorado, was studied to determine the relative abundance of invertebrate functional groups over an altitudinal gradient of 500 m during three seasons. The Dolores River is a third order stream with an average width of 11 m in the upper 8 km of the study area. In the lower 38 km of the study area, it is a fourth order stream with an average width of 15 m. Benthic invertebrates were collected with a modified Hess sampler in October 1980, and March and August 1981, from 11 stations on the Dolores River. Despite little change in either stream order, width or apparent food resources in the study area, there were noticeable differences in the relative abundance of functional groups, with shredders most abundant upstream and collectors most abundant in the mid-reaches. The observed trends were highly dependent upon season with shredders abundant at most stations only in spring. This was a result of life history patterns of winter stoneflies, the primary shredders. Collector-gatherers were most abundant at the upper-middle stations in summer, but were less abundant in the other two seasons. In general, the pattern appeared to conform more to the altitudinal shifts in benthic species composition than to stream order or width. This led to shifts in the assigned functional groups without noticeable changes in food resources.","PeriodicalId":154110,"journal":{"name":"Freshwater Invertebrate Biology","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1983-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123895893","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}

Larvae receiving wheat were able to override direct temperature effects, while those on alder could not. Based on larval growth rates, and pupal weights and lipid contents, we concluded that alder alone was a poor quality food for late instar C. magnifica. A diet of alder plus wheat allowed the most growth, and produced the largest pupae, however pupae from larvae given just wheat had the largest lipid stores. Among-treatment differences in protein and lipid content, and fatty acid composition verified the importance of fatty acids synthesized from dietary carbohydrate. It appears that a carbohydrate source for the metabolism of storage lipid is a major requirement for late instar C. magnifica.","PeriodicalId":154110,"journal":{"name":"Freshwater Invertebrate Biology","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1983-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125401414","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}

Shell growth of width to height was allometric and similar in pattern to another viviparid, Cipangopaludina chinensis. Growth rates were rapid after the lake warmed in spring and were negligible during winter. Mortality was relatively low for younger snails, and the death of the eldest cohort was a highly synchronized event occurring in late spring. Reproduction was semelparous. Females brooded a single batch of eggs for nine months during their third year (27-36 months old), released the young in April, and died at 38 months of age. The population demonstrated a migratory pattern which resulted in deep water winter aggregations and shallow water summer aggregations.
