Abstract
—The present study aimed to relate aquatic macroinvertebrate community composition to agricultural intensity and landscape structure. A total of 360 streams were investigated within the Aller river basin in northern Germany. The study area is typical of central German arable agricultural regions, but the small streams were of low dilution potential. These streams were characterized for abiotic parameters (including modeled potential for diffuse inputs from agricultural sources) and macroinvertebrate communities, with data collected over a 17‐year period. Spray drift potential did not correlate with community composition. In contrast, the relative index of runoff potential (RP) was negatively correlated with various measures of taxonomic richness and abundance. Community composition also was correlated with environmental parameters, including stream width, clay content of sediment, and presence of dead wood in sediment. The abundance of sensitive species decreased significantly during the main period of agrochemical use at sites of high RP but completely recovered by the following spring. Long‐term decreased taxonomic richness and a shift to ecologically robust species also were observed at sites of high RP. The results suggest that long‐term alterations in community measures probably were associated with factors related to runoff input. Nevertheless, the community composition remained reasonably rich and even. Landscape structure also appeared to influence community structure. Abundance of sensitive species remained significantly enhanced, even at sites of high RP, when forested reaches were present in upstream reaches. These probably provided a source of organisms for downstream recolonization and amelioration of effects at high RP.

A total of 360 streams were investigated within the Aller river basin in northern Germany.

These streams were characterized for abiotic parameters (including modeled potential for diffuse inputs from agricultural sources) and macroinvertebrate communities, with data collected over a 17‐year period.

The abundance of sensitive species decreased significantly during the main period of agrochemical use at sites of high RP but completely recovered by the following spring. Long‐term decreased taxonomic richness and a shift to ecologically robust species also were observed at sites of high RP. The results suggest that long‐term alterations in community measures probably were associated with factors related to runoff input.

A total of 360 streams were investigated within the Aller river basin in northern Germany. The study area is typical of central German arable agricultural regions, but the small streams were of low dilution potential. These streams were characterized for abiotic parameters (including modeled potential for diffuse inputs from agricultural sources) and macroinvertebrate communities, with data collected over a 17‐year period. Spray drift potential did not correlate with community composition. In contrast, the relative index of runoff potential (RP) was negatively correlated with various measures of taxonomic richness and abundance. Community composition also was correlated with environmental parameters, including stream width, clay content of sediment, and presence of dead wood in sediment. The abundance of sensitive species decreased significantly during the main period of agrochemical use at sites of high RP but completely recovered by the following spring. Long‐term decreased taxonomic richness and a shift to ecologically robust species also were observed at sites of high RP. The results suggest that long‐term alterations in community measures probably were associated with factors related to runoff input. Nevertheless, the community composition remained reasonably rich and even. Landscape structure also appeared to influence community structure. Abundance of sensitive species remained significantly enhanced, even at sites of high RP, when forested reaches were present in upstream reaches. These probably provided a source of organisms for downstream recolonization and amelioration of effects at high RP.</abstract><subject lang="en"><genre>keywords</genre><topic>Agricultural intensity</topic><topic>Runoff</topic><topic>Landscape structure</topic><topic>Recolonization</topic><topic>Recovery</topic></subject><relatedItem type="host"><titleInfo><title>Environmental Toxicology and Chemistry</title><subTitle>An International Journal</subTitle></titleInfo><titleInfo type="abbreviated"><title>Environmental Toxicology and Chemistry</title></titleInfo><genre type="journal">journal</genre><subject><genre>article-category</genre><topic>Environmental Toxicology</topic></subject><identifier type="ISSN">0730-7268</identifier><identifier type="eISSN">1552-8618</identifier><identifier type="DOI">10.1002/(ISSN)1552-8618</identifier><identifier type="PublisherID">ETC</identifier><part><date>2007</date><detail type="volume"><caption>vol.</caption><number>26</number></detail><detail type="issue"><caption>no.</caption><number>2</number></detail><extent unit="pages"><start>346</start><end>357</end><total>12</total></extent></part></relatedItem><identifier type="istex">5B946D55A613FBA39CCCE76327DB46321FBA4706</identifier><identifier type="DOI">10.1897/05-629R.1</identifier><identifier type="ArticleID">ETC5620260222</identifier><accessCondition type="use and reproduction" contentType="copyright">Copyright © 2007 SETAC</accessCondition><recordInfo><recordContentSource>WILEY</recordContentSource><recordOrigin>Wiley Periodicals, Inc.</recordOrigin></recordInfo></mods></metadata><serie></serie></istex></record>Pour manipuler ce document sous Unix (Dilib)
