Summary: | Pantanal is one of the largest humid areas in the world, characterized by changes during hydrological cycles, which correspond to periods that alternate during floods and ebbs. This study aimed to analyze the diet of Brycon hilarii (Valenciennes, 1850) in different hydrological periods of the Ecological Station of Taiamã in Mato Grosso, Brazil, a conservation unit of worldwide interest, and its relationship with the formation of vegetation. Were 353 specimens captured in monthly campaigns, during the four hydrological periods, from August 2013 to July 2015, then packed in thermal boxes and sent to the laboratory, where the biometric data and stomach removal were noted for analyzes of food importance (IAi). The results show that Erytrhina fusca Lour. (squash) is the main food item in the B. hilarii diet. During the flood periods, it had an IAi of 95% and at flood 60%. Furthermore, B. hilarii proved to be a generalist in feeding on E. fusca during periods of high, low and dry periods, being a specialist in the period of flood. According to the size of the specimen the volume of intact and crushed seeds in relation to the standard size, it was found that the seeds are ingested according to the size according to the size of the specimen. This fact contributes to the importance of hydrological periods, together with the E. fusca monodominance in the place, which provides an increase in food resources for B. hilarii, through strategies, coinciding with the greater availability of E. fusca in this environment. |

El objetivo de este estudio fue evaluar qué técnica de siembra directa (en pozos o lance) es más prometedora, y cuál es la influencia de la transposición de la hojarasca después de la siembra, para la emergencia y establecimiento inicial de la especie nativa Sterculia apetala (Jaqc.) H. Karst. en restauración ecológica en una zona de manantiales degradados en el municipio de Cáceres-MT, Pantanal Mato-Grossense. En este experimento se analizaron dos tecnicas de siembra directa (en pozos y lance) en dos ambientes diferentes (con y sin transposición de hojarasca), utilizando la planta nativa S. apetala. Todas las técnicas de siembra analizadas demostraron ser eficientes, obteniendo buenos porcentajes de emergencia y establecimiento, sin embargo, la siembra directa en fosas con transposición de hojarasca (T2), resultó ser la técnica más eficiente en todos los parámetros evaluados para S. apetala en este experimento. La transposición de hojarasca después de la siembra directa (T2 y T4), mostró una influencia positiva en el establecimiento de plántulas para todos los parámetros analizados, provocando plantas más vigorosas al final del experimento.O pantanal é uma das maiores áreas úmidas do mundo, caracterizada por apresentar alterações durante os ciclos hidrológicos, que correspondem a períodos que se alternam durante enchentes e vazantes. Este estudo teve como objetivo analisar a dieta de Brycon hilarii (Valenciennes, 1850), em diferentes períodos hidrológicos da Estação Ecológica de Taiamã em Mato Grosso Brasil, uma unidade de conservação de interesse mundial, e sua relação com a formação vegetacional. Foram capturados 353 espécimes em campanhas mensais, durante os quatro períodos hidrológicos, nos meses de agosto de 2013 a julho de 2015, em seguida, acondicionados em caixas térmicas e encaminhado para o laboratório, onde foram anotados os dados biométricos e a remoção dos estômagos para as análises de importância alimentar (IAi). Os resultados mostram que Erythrina fusca Lour. (abobreiro) é o principal item alimentar da dieta de B. hilarii. Durante os períodos de enchente, apresentou IAi de 95% e na cheia 60%. Além disso, B. hilarii mostrou ser generalista em se alimentar de E. fusca durante os períodos de cheia, vazante e estiagem, sendo especialista no período de enchente. Com relação do volume de sementes intactas e trituradas comparado ao tamanho padrão, verificou-se que as sementes são ingeridas conforme o tamanho do espécime. Este fato contribui com a importância dos períodos hidrológicos, junto a monodominancia de E. fusca no local, o que propicia o aumento de recursos alimentares para B. hilarii, através de estratégias, coincidindo com a maior disponibilidade de E. fusca neste ambiente.Research, Society and Development2021-03-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1385010.33448/rsd-v10i4.13850Research, Society and Development; Vol. 10 No. 4; e3910413850Research, Society and Development; Vol. 10 Núm. 4; e3910413850Research, Society and Development; v. 10 n. 4; e39104138502525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/13850/12466Copyright (c) 2021 Michelle do Espírito Santo Bertolino; Ernandes Sobreira Oliveira Junior; Daniel Luis Zanella Kantek; Bruna dos Santos França; Alexandre Forgiarini Bastos Aniceto; Claumir Cesar Munizhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessBertolino, Michelle do Espírito Santo Oliveira Junior, Ernandes SobreiraKantek, Daniel Luis Zanella França, Bruna dos Santos Aniceto, Alexandre Forgiarini BastosMuniz, Claumir Cesar 2021-04-25T11:21:26Zoai:ojs.pkp.sfu.ca:article/13850Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:35:06.377669Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
