Resumo: | The objective of this work was to determine seasonal variation and vertical distribution of the soil rotifer assemblage in a climax beech forest in South Bohemia. During 2005, soil rotifer was investigated to the species level. Soil samples of 10 cm2 and 10 cm in depth were divided into five layers, which were processed separately. Thirty one rotifer species were identified during the investigation. Dominant species significantly changed throughout the seasons. The most abundant species were Encentrum arvicola and Wierzejskiella vagneri among the monogononts, and Adineta steineri, Ceratotrocha cornigera, Habrotrocha filum, Habrotrocha ligula, Macrotrachela plicata, Mniobia tentans, Mniobia incrassata and Mniobia granulosa among the bdelloids. Mean Shannon diversity index varied from 1.99 to 2.63. Total rotifer abundance varied from 212±63 to 513±127 103 individuals m-2 along the year, with the highest numbers found in May, and the lowest in July. The great part of the community was concentrated in the upper (fresh litter) and second (partially decomposed litter) layers and significantly decreased in the soil vertical profile on all sampling dates. The highest rotifer density of 43 individuals g-1 was found in the upper layer in May. |

Durante 2005, as comunidades de rotíferos edáficos foram estudadas até o nível da espécie. Amostras de 10 cm2 de área com 10 cm de profundidade foram divididas em cinco camadas, que foram processadas separadamente. Trinta e uma espécies de rotíferos foram identificadas durante a investigação. Todas as espécies dominantes tiveram variações significativas durante as estações climáticas. As espécies mais abundantes foram Encentrum arvicola e Wierzejskiella vagneri entre os monogonontes e Adineta steineri, Ceratotrocha cornigera, Habrotrocha filum, Habrotrocha ligula, Macrotrachela plicata, Mniobia tentans, Mniobia incrassata e Mniobia granulosa entre os bdelloides. O índice médio de diversidade de Shannon variou entre 1,99 e 2,63. A abundância total de rotíferos variou entre 212±63 e 513±127 103 indivíduos por m2 ao ano, com os maiores números encontrados em maio e os menores em julho. A maior parte da comunidade estava concentrada na camada superior (liteira fresca) e na segunda camada (liteira parcialmente decomposta) e diminuiu significativamente no perfil vertical do solo em todas as datas de coleta. A maior densidade de rotíferos, de 43 indivíduos g-1, foi encontrada na camada superior em maio.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraGrant Agency of the Czech RepublicGrant Agency of the Czech RepublicDevetter, Miloslav2010-11-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/1400Pesquisa Agropecuaria Brasileira; v.44, n.8, ago. 2009: Thematic Issue XV International Colloquium on Soil Zoology and XX Colloquium on Apterygota; 1027-1032Pesquisa Agropecuária Brasileira; v.44, n.8, ago. 2009: Thematic Issue XV International Colloquium on Soil Zoology and XX Colloquium on Apterygota; 1027-10321678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/1400/5800https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/1400/963https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/1400/964https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/1400/965https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/1400/966https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/1400/967info:eu-repo/semantics/openAccess2012-06-17T11:52:08Zoai:ojs.seer.sct.embrapa.br:article/1400Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2012-06-17T11:52:08Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
