In addition, we also evaluated possible differences in the decomposition rates in the interior and at the border of the fragment and what the effect of the urban impact (matrix) on the structure of the fungal community and the decomposition process. Living branches still attached to the trees were cut and gathered inside a 1 m<sup>2<\/sup> plot. For each plant species, three specimens (<em>Alchornea sidifolia, Piptadenia gonoacantha<\/em> e <em>Calyptranthes grandifolia<\/em>), that were placed in four different Sites of the forest, two in the borders and two in the interior of the fragment. These branches were monitored for two years, with samples taken every 4 months (called &#8220;Time 0&#8221; to &#8220;Time 6&#8221;) for the identification of fungal species. The levels of lignin, cellulose, hemicellulose and nitrogen in the decomposing branches over time were quantified, besides the microclimate of the different sampling Sites were characterized. It was possible to notice the gradual reduction of wood density as well as its main components, demonstrating that there is an intense process of nutrient cycling, in some samples the loss of mass during the two years reached 70%. A low correlation was found in the association of community structure and succession with biochemical variation of wood, as well as between community variations and microclimatic factors. When correlated the fungal community patterns and the biochemistry of wood as a function of the edge and interior of the forest fragment, there was no influence on the decomposition process. Using new generation sequencing, a total of 3,037 OTUs (Operational Taxonomic Units) were recorded. Among them, 10 phyla, 33 classes, 88 orders, 177 families and 319 genera were identified, and the most abundant OTUs in the samples were invariably species of the Ascomycota phylum. It was also evaluated if the samples varied in species abundance and abundance over time. In terms of OTUs richness, it was found that there was a variation in the fungal community over time; initially the wealth is greater and that of the time this wealth of species falls sharply. The heat map showed a greater dissimilarity between the samples from Time 0 to Time 6. Time 1 and Time 2 showed a high similarity, suggesting an overlap of species abundance and abundance. At Time 3, it is possible to note a transition phase; Times 4, 5 and 6 are, in turn, more dissimilar to each other, constituting another phase of succession. In a comparison of the presence \/ absence of OTUs in the three tree species it is possible to notice a closer relation between <em>Alchornea<\/em> and <em>Piptadenia<\/em>, and <em>Calyptranthes <\/em>as the most different. From Time 0 to Time 2, especially at time 1 and 2, the Ascomycota phylum is highly abundant and, from time 3, a predominance of the phylum Basidiomycota is observed along with a general decline in abundance. Based on the data exploration presented here, it is concluded that the pattern in the decomposition of the wood depends on (or is influenced by) the species that participate in the succession and the abundance of the wood during the process and that there is a trend of succession of species during the decomposition of the wood, in addition to that the abundance of species can be an indicative of the decomposition pattern of the wood.<\/p>\n<p style=\"text-align: justify\"><strong>Keywords:\u00a0<\/strong>Microbial ecology; Fungal succession; Tropical forest<\/p>\n<h4 style=\"text-align: center\"><strong>RESUMO<\/strong><\/h4>\n<p style=\"text-align: justify\">Esse trabalho descreveu o processo de degrada\u00e7\u00e3o da madeira num fragmento de Mata Atl\u00e2ntica paulista, avaliando a varia\u00e7\u00e3o das esp\u00e9cies de fungos que ocorrem ao longo de dois anos de estudo presentes nos galhos de tr\u00eas esp\u00e9cies arb\u00f3reas que ocorrem na \u00e1rea. Al\u00e9m disso, tamb\u00e9m foram avaliadas poss\u00edveis diferen\u00e7as nas taxas de decomposi\u00e7\u00e3o no interior e na borda do fragmento e qual o efeito do impacto urbano (matriz) na estrutura da comunidade f\u00fangica e no processo de decomposi\u00e7\u00e3o. Ramos vivos ainda presos \u00e0s \u00e1rvores foram cortados e reunidos dentro de uma parcela de 1 m<sup>2<\/sup>. Para cada esp\u00e9cie vegetal foram escolhidos tr\u00eas esp\u00e9cimes (<em>Alchornea sidifolia, Piptadenia gonoacantha<\/em> e <em>Calyptranthes grandifolia<\/em>), que foram colocados em quatro pontos diferentes da floresta, dois nas bordas e dois no interior do fragmento. Esses galhos foram monitorados por dois anos, com coletas de amostras a cada 4 meses (chamados de &#8220;Tempo 0&#8221; at\u00e9 &#8220;Tempo 6&#8221;) para a identifica\u00e7\u00e3o de esp\u00e9cies f\u00fangicas. Os teores de lignina, celulose, hemicelulose e nitrog\u00eanio nos galhos em decomposi\u00e7\u00e3o ao longo do tempo foram quantificados, al\u00e9m de serem caracterizados o microclima dos diferentes pontos de amostragem. Foi poss\u00edvel perceber a gradual redu\u00e7\u00e3o da densidade da madeira, bem como de seus componentes principais, mostrando que h\u00e1 um processo intenso de ciclagem de nutrientes, em algumas amostras a perda de massa ao longo dos dois anos chegou a 70%. Percebeu-se uma baixa correla\u00e7\u00e3o na associa\u00e7\u00e3o da estrutura e sucess\u00e3o da comunidade com a varia\u00e7\u00e3o bioqu\u00edmica da madeira, bem como entre as varia\u00e7\u00f5es da comunidade e os fatores microclim\u00e1ticos. Quando correlacionados os padr\u00f5es da comunidade f\u00fangica e a bioqu\u00edmica da madeira em fun\u00e7\u00e3o da borda e interior do fragmento florestal, n\u00e3o houve influ\u00eancia no processo de decomposi\u00e7\u00e3o. Usando sequenciamento de nova gera\u00e7\u00e3o, obteve-se um total de 3 037 OTUs (Unidades Taxon\u00f4micas Operacionais). Entre eles, foram identificados 10 filos, 33 classes, 88 ordens, 177 fam\u00edlias e 319 g\u00eaneros, sendo que as OTUs mais abundantes nas amostras foram invariavelmente esp\u00e9cies do filo Ascomycota. Foi avaliado ainda se as amostras variavam em riqueza e abund\u00e2ncia de esp\u00e9cies ao longo do tempo. Em termos de riqueza de OTUs, verificou-se que, houve uma varia\u00e7\u00e3o na comunidade f\u00fangica ao longo do tempo; inicialmente a riqueza \u00e9 maior e que ao longo do tempo essa riqueza de OTUs decresce. O mapa de calor mostrou uma maior dissimilaridade entre as amostras do Tempo 0 para o Tempo 6. O Tempo 1 e o Tempo 2, mostraram uma alta similaridade, sugerindo uma sobreposi\u00e7\u00e3o de riqueza e abund\u00e2ncia de esp\u00e9cies. No Tempo 3, \u00e9 poss\u00edvel notar uma fase de transi\u00e7\u00e3o; os Tempos 4, 5 e 6 por sua vez, s\u00e3o mais dissimilares entre si, constituindo outra fase da sucess\u00e3o. Em uma compara\u00e7\u00e3o de presen\u00e7a\/aus\u00eancia de OTUs nas tr\u00eas esp\u00e9cies de \u00e1rvores \u00e9 poss\u00edvel notar uma rela\u00e7\u00e3o mais pr\u00f3xima entre as esp\u00e9cies de <em>Alchornea<\/em> e <em>Piptadenia<\/em>, e <em>Calyptranthes<\/em> como a mais diferente. Do Tempo 0 ao Tempo 2, especialmente no tempo 1 e 2, o filo Ascomycota \u00e9 altamente abundante e, a partir do tempo 3, observa-se uma predomin\u00e2ncia do filo Basidiomycota, juntamente com um decl\u00ednio geral na abund\u00e2ncia. Com base na explora\u00e7\u00e3o de dados aqui apresentada, conclui-se que o padr\u00e3o na decomposi\u00e7\u00e3o da madeira depende das (ou \u00e9 influenciado pelas) esp\u00e9cies que participam da sucess\u00e3o e da abund\u00e2ncia das mesmas durante o processo e que h\u00e1 uma tend\u00eancia de sucess\u00e3o de esp\u00e9cies durante a decomposi\u00e7\u00e3o da madeira, al\u00e9m de que a abund\u00e2ncia de esp\u00e9cies pode ser um indicativo do padr\u00e3o de decomposi\u00e7\u00e3o da madeira.<\/p>\n<p style=\"text-align: justify\"><strong>Palavras-chave:\u00a0<\/strong>Ecologia microbiana; Sucess\u00e3o f\u00fangica; Floresta tropical<\/p>\n<hr align=\"center\" noshade=\"noshade\" size=\"1\" width=\"100%\" \/>\n<p style=\"text-align: center\"><a href=\"https:\/\/smastr16.blob.core.windows.net\/pgibt\/sites\/242\/2024\/07\/ricardo_matheus_pires_dr.pdf\" target=\"_blank\" rel=\"noopener\"><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter\" src=\"https:\/\/smastr16.blob.core.windows.net\/pgibt\/2013\/09\/pdf_grande.gif\" alt=\"pdf_grande\" width=\"60\" height=\"60\" \/><\/a><a href=\"https:\/\/smastr16.blob.core.windows.net\/pgibt\/sites\/242\/2024\/07\/ricardo_matheus_pires_dr.pdf\">Ricardo Matheus Pires<\/a><br \/>\n<a href=\"https:\/\/smastr16.blob.core.windows.net\/pgibt\/sites\/242\/2024\/07\/ricardo_matheus_pires_dr.pdf\">An\u00e1lise da decomposi\u00e7\u00e3o de madeira em fragmento de mata atl\u00e2ntica: estrutura da comunidade f\u00fangica, caracteriza\u00e7\u00e3o do substrato e o processo sucessional<\/a><\/p>\n<hr align=\"center\" noshade=\"noshade\" size=\"1\" width=\"100%\" \/>\n<p style=\"text-align: center\"><strong>\u00a0<a href=\"www.infraestruturameioambiente.sp.gov.br\/pgibt\/dissertacoesteses\/\">VOLTAR AS DISSERTA\u00c7\u00d5ES E TESES<\/a><\/strong><\/p>\n<hr align=\"center\" noshade=\"noshade\" size=\"1\" width=\"100%\" \/>\n","protected":false},"excerpt":{"rendered":"<p>Ricardo Matheus Pires Em 22 de agosto de 2019, no anfiteatro do Instituto de Bot\u00e2nica de S\u00e3o Paulo (IBt), o aluno da P\u00f3s-Gradua\u00e7\u00e3o em Biodiversidade Vegetal e Meio Ambiente do Instituto de Bot\u00e2nica de S\u00e3o Paulo (IBt), Ricardo Matheus Pires (Bolsista FAPESP), defendeu a sua Tese de Doutorado intitulada \u201cAn\u00e1lises da decomposi\u00e7\u00e3o de madeira em [&hellip;]<\/p>\n","protected":false},"author":187,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":[],"_links":{"self":[{"href":"https:\/\/www.infraestruturameioambiente.sp.gov.br\/pgibt\/wp-json\/wp\/v2\/pages\/9231"}],"collection":[{"href":"https:\/\/www.infraestruturameioambiente.sp.gov.br\/pgibt\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.infraestruturameioambiente.sp.gov.br\/pgibt\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.infraestruturameioambiente.sp.gov.br\/pgibt\/wp-json\/wp\/v2\/users\/187"}],"replies":[{"embeddable":true,"href":"https:\/\/www.infraestruturameioambiente.sp.gov.br\/pgibt\/wp-json\/wp\/v2\/comments?post=9231"}],"version-history":[{"count":3,"href":"https:\/\/www.infraestruturameioambiente.sp.gov.br\/pgibt\/wp-json\/wp\/v2\/pages\/9231\/revisions"}],"predecessor-version":[{"id":9277,"href":"https:\/\/www.infraestruturameioambiente.sp.gov.br\/pgibt\/wp-json\/wp\/v2\/pages\/9231\/revisions\/9277"}],"wp:attachment":[{"href":"https:\/\/www.infraestruturameioambiente.sp.gov.br\/pgibt\/wp-json\/wp\/v2\/media?parent=9231"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
