Resumo: | Studies on seed rain can provide useful information on the spatial distribution, density, and richness of species. This study aimed to sample the seed rain in “capões” with the presence and absence of Copernicia prunifera (Carnaúba), characterizing the seeds as for their dispersion syndrome and life forms, and explore the relationship between the monthly rainfall totals and the density and number of species in the seed rain and the seasonality in seed deposition. The research was conducted in 20 capões, (10 with the presence and 10 with the absence of Copernicia prunifera). Three collectors of 0.50 m2 were placed in each capão. A total of 1,666 diaspores (55.5 seeds/m2), belonging to 17 families and 32 species, were collected. There was a negative relationship between rainfall and the number of seeds (r = -0.73 and p<0.05) and between rainfall and number of species in the seed rain (r = -0.78 and p<0.01). There was an increase in the number of species in the seed rain with an increase in the number of seeds (r = 0.74 and p<0.001). Twelve zoochoric, 12 anemochoric, and 7 autochoric species were recorded, which accounted for 908, 502, and 256 seeds, respectively. Trees had 895 seeds collected, distributed in 12 species, followed by shrubs (574 seeds and 10 species), lianas (133 seeds and 7 species), and palms (61 seeds and 2 species). Anemochoric and zoochoric dispersion syndromes predominated in the dry period, with a predominance of zoochory in all months. There was a difference in the species composition in the seed rain between the capões with the presence and with the absence of Copernicia prunifera. The distance between the capões did not influence the seed rain composition (Mantel r = -0.11 and p = 0.74). There was no relationship between areas of capões and the number of seeds in the seed rain (R2 = 0.013 and p = 0.95). |

O objetivo deste trabalho foi amostrar a chuva de sementes em Capões com presença e ausência de Copernicia prunifera (Carnaúba), caracterizar as sementes quanto à síndrome de dispersão e forma de vida, explorar a relação entre os totais pluviométricos mensais com a densidade e número de espécies da chuva de sementes e a estacionalidade na deposição de sementes. O estudo foi realizado em 20 Capões, sendo 10 com presença e 10 com ausência de Carnaúba. Cada Capão recebeu três coletores com área de 0,50 m2. Foram coletados 1.666 diásporos (55,5 sementes/m2) pertencentes a 17 famílias e 32 espécies. Houve relação negativa entre pluviosidade e número de sementes (r = -0,73 e p<0,05) e, entre pluviosidade e número de espécies da chuva de sementes (r = -0,78 e p<0,01). Houve aumento no número de espécies da chuva de sementes com o aumento de sementes da chuva de sementes (r = 0,74 e p< 0,001). Foram levantadas 908 sementes zoocóricas distribuídas em 12 espécies, anemocoria 502 sementes e 12 espécies e autocórica 256 sementes e sete espécies. As espécies arbóreas tiveram 895 sementes distribuídas em 12 espécies, os arbustos 574 sementes e 10 espécies, as Lianas 133 sementes e sete espécies e palmeiras com 61 sementes e duas espécies. As síndromes de dispersão anemocórica e zoocórica foram predominantes no período seco e zoocoria em todos os meses. Foi observada diferença na composição de espécies da chuva de sementes entre os Capões com presença e ausência de Carnaúba. A distância entre os Capões não influenciou na composição da chuva de sementes (Mantel r = -0,11e p = 0,74). Não houve relação entre áreas dos Capões com o número de sementes da chuva de sementes (R2 = 0,013 e p = 0,95).Universidade Federal de Santa Maria2022-06-24info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmltext/xmlhttps://periodicos.ufsm.br/cienciaflorestal/article/view/4685910.5902/1980509846859Ciência Florestal; Vol. 32 No. 2 (2022); 673-697Ciência Florestal; v. 32 n. 2 (2022); 673-6971980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/46859/47526https://periodicos.ufsm.br/cienciaflorestal/article/view/46859/48343https://periodicos.ufsm.br/cienciaflorestal/article/view/46859/50737Copyright (c) 2022 Ciência Florestalhttp://creativecommons.org/licenses/by-nc/4.0info:eu-repo/semantics/openAccessMorais, Rodrigo Ferreira deMacedo, Maria Thamiris de Sousa MacedoIbiapina, Ronaldo de AraújoSantiago Junior, Luiz Carlos Teixeira, Jefferson da SilvaMorais, Fernando Ferreira deSousa Júnior, José Ribamar2022-12-15T02:20:26Zoai:ojs.pkp.sfu.ca:article/46859Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2022-12-15T02:20:26Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
