Lake-wide distribution was correlated with substrate type and the size and consistency of matrix particle composition. Exposure, ice scouring, silt accumulation and possible negative interactions with algae apparently affected the upper limits of the littoral vertical distribution. The lower limits were correlated with the adverse impact of silt abundance on sponge colony filtering capacity and larval settlement. Rock substrate found in water deeper than approximately 1.5 m maintained a relatively nonfluctuating, stable portion of the sponge population. At the third habitat level, rock surface preference, silt accumulation and possible harmful biotic interactions apparently caused the sponge to colonize the vertical and bottom surfaces of rubble.","PeriodicalId":154110,"journal":{"name":"Freshwater Invertebrate Biology","volume":"136 8","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1984-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114094490","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}

To determine the effect of this intermittent mode of operation on downstream conditions, data on benthic macroinvertebrates, temperature, current velocity, width and depth were collected for 13 months at 5 sites along 15 km of the Sturgeon River immediately downstream from the hydrostation and at an upstream control site. During station operation, current velocity increased 2.6 times 200 m downstream and 1.2 times 10 km downstream, while depth increased 75 cm and 35 cm, respectively. Depending on stream morphology, width increased 0 to 10 m during operation. Maximum temperatures observed were 22°C upstream, 24.5°C immediately downstream from the station and 23°C 10 km downstream. When the station was shut down, temperature fluctuation patterns were similar above and below the hydrostation. During operation, temperature fluctuations were reduced downstream. At the site 200 m below the hydrostation, invertebrate biomass averaged 6.9 times greater than at the upstream site and 2.5 times greater than 10 km downstream. The average number of taxa collected 200 m below the station was 12% less than at the upstream site and the site 10 km downstream, and included 6 genera of stoneflies, 9 genera of mayflies and 10 genera of caddisflies. Intermittent operation of this hydroelectric station did not have a severe adverse effect on downstream benthos and produced downstream temperature fluctuation patterns more like those upstream than would continuous operation.","PeriodicalId":154110,"journal":{"name":"Freshwater Invertebrate Biology","volume":"10 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1984-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126101105","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}

Brown","doi":"10.2307/1467127","DOIUrl":"https://doi.org/10.2307/1467127","url":null,"abstract":"Extensive quantitative sampling of aquatic insects and factors known or suspected to affect their local distribution in streams was performed in three consecutive riffles in a hardwater stream of north central Texas, USA. This study revealed a strong upstream-biased distribution pattern of lotic insects within riffles. Twelve of sixteen taxonomic categories analyzed, representing 93.4% of the total numbers, showed a distinct pattern of distribution with greater abundance toward the heads of riffles. Density of insects was statistically correlated with several physical and chemical characteristics measured including quantity of coarse particulate organic matter on the substrate, quantity of fine particulate organic matter in transport, several substrate particle size classes, current, depth, dissolved oxygen and temperature. However, none of these variables were meaningfully correlated with distance from the heads of riffles, and therefore did not sufficiently explain distribution of the insect groups. Positive rheotaxis could have significant influence on distribution of insects in riffles. The observed distribution pattern indicates that filter-feeding riffle insects compete for high quality food items produced in upstream pools, and that density of macrobenthos within these riffles may be limited by the amount of high quality food available to them rather than by space.","PeriodicalId":154110,"journal":{"name":"Freshwater Invertebrate Biology","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1984-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125946895","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}

Tests were carried out in Petri dishes containing one freshly hatched Mesostoma and one mosquito larva of the following species: Aedes aegypti, Anopheles stephensi and Culiseta melanura. Efficiency of M. appia varied from 50-90% of third and fourth instar larvae killed in 24 h and depends on the mosquito species. Individuals of Aedes and Anopheles are more susceptable than those of Culiseta. Other species of Mesostoma are less efficient against late instars but always eliminated more than 50% of the second instar larvae in 24 h. Differences in efficiency of predation are attributed to different sizes of predator species and to behavioral characteristics of mosquito species.","PeriodicalId":154110,"journal":{"name":"Freshwater Invertebrate Biology","volume":"122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1984-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134120459","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}

Its occurrence in New York State is the first record of the genus outside the Palearctic region. In general, the New York specimens conformed to the morphological traits of the Palearctic material, but none were more than half as long as the known maximum length, some dorsal and ventral chaetae were somewhat shorter, and the penial chaetae were occasionally more numerous and always considerably longer. The New York specimens were collected from hardboard artificial substrate samplers, usually with several other species of naidids. The use of artificial substrates may have been instrumental in finding the species, since it is known to live on the surfaces of submerged objects, rather than on the benthic substrate per se.","PeriodicalId":154110,"journal":{"name":"Freshwater Invertebrate Biology","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1984-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125096585","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}
