PEREZ-VASQUEZ, Nabi Del Socorro; ARIAS-RIOS, Jorge  e  QUIROS-RODRIGUEZ, Jorge Alexander. Space-time Variation of Aquatic Vascular Plants in Complex Low Swampy Sinú, Córdoba, Colombia. Acta biol.Colomb. [online]. 2015, vol.20, n.3, pp.155-165. ISSN 0120-548X.  https://doi.org/10.15446/abc.v20n3.45380.

The space-time variation of vascular aquatic vegetation was studied in Maria Arriba, San Sebastian, Purísima and Momil swamps of the lower Sinú swamp complex, located in the department of Córdoba (Colombia), covering hydrological periods occurred in one year. The area of study was divided in four sectors and by the linear intercept method it was determined the abundance and frequency of the hydrophytes. They were recorded 39659 individuals distributed in 24 families, 30 genus and 35 species. The highest abundance of species was presented in Momil with 18582 individuals being the family Lemnaceae the most representative. The analysis of variance (ANOVA) shows that not exist statistically significantly different in the abundance of the species of aquatic plants from sampling months (F = 1,04; GL = 11; p = 0,083), however, it has demonstrated the incidence of a hydrological period on the plants dynamic growth, some species disappear in dry season, others survive for a short period of time, while others like Lemna minor L. y Salvinia auriculata Aubl. increase in the rainy season.
