The reservoirs of the upper Juramento basin (Cabra Corral and El Tunal) and the Salí-Dulce basin (El Cadillal, Río Hondo, and Escaba) show certain peculiarities due to their geographical location, basin morphology and limnological features. Such peculiarities were compared during significant algal b...

description The reservoirs of the upper Juramento basin (Cabra Corral and El Tunal) and the Salí-Dulce basin (El Cadillal, Río Hondo, and Escaba) show certain peculiarities due to their geographical location, basin morphology and limnological features. Such peculiarities were compared during significant algal bloom periods between 2002 and 2008, by analyzing the main physicochemical parameters and ecological attributes of the phytoplankton assemblages using standard methods. Tucumán reservoirs were different in most variables showing higher values of conductivity, nutrients and algal biomass. Regarding the hydrological cycle, El Cadillal exhibited the lowest biomass average (2.74 mg Chl.m-3) during maximum water flows, whereas the Cabra Corral lacustrine zone exhibited the highest biomass average (63.36 mg Chl.m-3) during minimum water flows. For the same period, the Cabra Corral lacustrine zone exhibited lower phytoplankton diversity and richness (1.37 and 9, respectively), in accordance with dinophyte blooms of Ceratium sp. In all reservoirs, the following biological variables showed a significant contrast in the hydrological cycle: highest phytoplankton biomass during minimum water flows (35.68 mg Chl-a m-3) vs. waterfloods (13.68 mg Chl-a m-3) (T = 3.42, P = 0.001). During minimum water flows, richness (14.30 sp.) and equitability (0.51) were lower vs. waterfloods (20.23, 0.59, respectively) (T = 2.36; P = 0.0196), as a result of the allochthonous nutrients provided by the main tributaries. Management of the reservoirs’ hydrometric levels during dry season determines the deterioration of the water quality with increased algal blooms. In order to ensure the systems’ sustainability, eutrophication must be controlled with programs to reduce diffuse nutrient loads and to treat residential and agroindustrial effluents, particularly in Sali-Dulce basin.

Los embalses de Tucumán se diferenciaron en la mayoría de las variables con valores más elevados de conductividad, nutrientes y biomasa de algas. En función del ciclo hidrológico, El Cadillal en aguas altas presentó el promedio más bajo de biomasa (2.74 mg Cl.m-3) y en contraste Cabra Corral el más elevado (63.36 mgCl.m-3) durante los caudales mínimos de agua. En éste último, en el mismo período, también la diversidad y riqueza de especies del fitoplancton fueron menores (1.37 y 9 respectivamente), en concordancia con las proliferaciones de dinófitos (Ceratium sp.). Las siguientes variables biológicas en el conjunto de embalses presentaron un contraste significativo en el ciclo hidrológico: biomasa del fitoplancton más elevada en estiaje (35.68 mg Cl a. m-3) versus crecidas (13.68 mg Cl a. m-3) (T = 3.42; P = 0.001). En estiaje, la riqueza (14.30 sp) y equitatividad (0.51) fueron menores versus crecidas (20.23, 0.59, respectivamente) (T = 2.36; P = 0.0196), debido al aporte alóctono de nutrientes por los tributarios principales. El manejo de los niveles hidrométricos de los embalses durante el estiaje determina el deterioro de la calidad de sus aguas con incremento de proliferaciones algales. Para asegurar la sustentabilidad de los sistemas, es indispensable el control de la eutrofización mediante programas de reducción de cargas difusas de nutrientes y tratamiento de efluentes domiciliarios y agroindustriales, particularmente en la cuenca del Sali-Dulce.Universidad de Costa Rica2018-03-01info:eu-repo/semantics/publishedVersionArticleartículo originalhttp://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/articleapplication/pdftext/htmlapplication/vnd.openxmlformats-officedocument.wordprocessingml.documenthttps://revistas.ucr.ac.cr/index.php/rbt/article/view/2661310.15517/rbt.v66i1.26613Revista de Biología Tropical; Vol. 66 No. 1 (2018): Volume 66 – Regular number 1 – March 2018; 415–427Revista de Biología Tropical; Vol. 66 Núm. 1 (2018): Volumen 66 – Número regular 1 – Marzo 2018; 415–427Revista Biología Tropical; Vol. 66 N.º 1 (2018): Volumen 66 – Número regular 1 – Marzo 2018; 415–4272215-20750034-774410.15517/rbt.v66i1reponame:Portal de Revistas UCRinstname:Universidad de Costa Ricainstacron:UCRenghttps://revistas.ucr.ac.cr/index.php/rbt/article/view/26613/31912https://revistas.ucr.ac.cr/index.php/rbt/article/view/26613/31913https://revistas.ucr.ac.cr/index.php/rbt/article/view/26613/35288Derechos de autor 2018 Revista de Biología Tropicalhttp://creativecommons.org/licenses/by/4.0acceso abiertohttp://purl.org/coar/access_right/c_abf2info:eu-repo/semantics/openAccess2022-06-09T18:12:57Zoai:portal.ucr.ac.cr:article/26613Portal de revistashttps://revistas.ucr.ac.cr/Universidadhttp://www.ucr.ac.crhttps://revistas.ucr.ac.cr/index.php/index/oaijorge.polanco@ucr.ac.crCosta RicaNo aplicaNo aplicaNo aplicaopendoar:2025-08-13T10:22:20.867Portal de Revistas UCR - Universidad de Costa Ricafalse
