Resumo: | Mangroves are one of the most productive ecosystems on the planet however they have undergone progressive environmental changes due to anthropic pressures. Information on phenological behavior can be used as an instrument in the construction of conservation projects of natural resources. The present study was carried out in four estuarine areas in Acaraú, Ceará, Brazil, with the aim of analyzing of phenological behavior regarding reproductive components of three mangrove species in different areas subject to different environmental impacts (solid waste, deforestation and shrimp farm effluent) and a low impacted area, during a period of one year. patterns of flowering and fruiting: Fournier Index (percentage of intensity) and the index of activity. The flowering of Avicennia spp. and Rhizophora mangle, under natural conditions, occurred all year round, and it showed irregular patterns. Regarding fruiting, Laguncularia racemosa was the species that presented the highest values for the two phenological indices analyzed. Rainfall and salinity seemed to exert a more selective force when species were subjected to an anthropic impact. The comparative analysis of the different phenological evaluation methods carried out in this study indicated that they provide different and complementary data about the reproductive behavior of the plant and how the impacts to which these environments are subjected may be negatively interfering with the flora of this ecosystem. |

Informações sobre o comportamento fenológico podem ser utilizadas como instrumento na construção de projetos de conservação de recursos naturais. O presente estudo foi realizado em quatro áreas estuarinas em Acaraú, Ceará, objetivando analisar o comportamento fenológico dos componentes reprodutivos de três espécies de mangue em diferentes áreas sujeitas a diferentes tipos de impactos ambientais (resíduos sólidos, desmatamento e efluentes da carcinicultura) e uma área de baixo impacto no período de um ano. A fim de se caracterizar os padrões fenológicos foi realizada observação direta, registrando-se a presença e a intensidade da floração e frutificação. Dois métodos de análise foram aplicados para entender os padrões de floração e frutificação: percentual de intensidade de Fournier e o índice de atividade. As florações de Avicennia spp. e Rhizophora mangle L, em condições naturais, ocorrem o ano todo, e nas áreas impactadas mostraram padrões irregulares. Quanto à frutificação, Laguncularia racemosa (L.) C. F. Gaertn foi a espécie que apresentou os mais altos percentuais para os dois índices fenológicos analisados. A pluviosidade e a salinidade parecem exercer maior força seletiva quando as espécies estão sujeitas a algum tipo de impacto antrópico. A análise comparativa dos diferentes métodos de avaliação fenológicos realizados neste estudo indicou que estes fornecem dados distintos e complementares sobre o comportamento reprodutivo vegetal e de como os impactos a que estes ambientes estão sujeitos pode estar interferindo negativamente sobre a flora deste ecossistema.Universidade Federal de Santa Maria2021-11-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmltext/xmlhttps://periodicos.ufsm.br/cienciaflorestal/article/view/3968310.5902/1980509839683Ciência Florestal; Vol. 31 No. 4 (2021); 1631-1653Ciência Florestal; v. 31 n. 4 (2021); 1631-16531980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/39683/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/39683/49108https://periodicos.ufsm.br/cienciaflorestal/article/view/39683/52456Copyright (c) 2021 Ciência Florestalhttp://creativecommons.org/licenses/by-nc/4.0info:eu-repo/semantics/openAccessBenevides, Jorgeana AlmeidaMaia, Rafaela CamargoSilva, Ingrid H’Oara Carvalho Vaz da2023-04-20T17:31:23Zoai:ojs.pkp.sfu.ca:article/39683Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2023-04-20T17:31:23Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
