“…Phytoplankton, the basic food of planktonic herbivores, may have their growth impaired by dense macrophyte stands (Gopal and Goel, 1993;Søndergaard and Moss, 1998) due to shading (Mulderij et al, 2007), competition for nutrients (Carpenter and Lodge, 1986), sedimentation of non-floating algae (Horppila and Nurminen, 2005) and allelopathy (Mulderij et al, 2005;Zhang et al, 2015).…”

The occupation of the littoral and limnetic zones by planktonic species has led to questions about whether littoral macrophytes would be a suitable habitat or refuge. These questions guided our field and laboratory studies on the spatial occupation and the food suitability for microcrustaceans of a shallow tropical lake. Replicated zooplankton samples were collected over 18 days, at intervals of 3 days, at three zones (the middle and edge of the stands of the emergent macrophyte, Ludwigia sp., and the limnetic zone). Some species, such as the cladocerans Diaphanosoma birgei and Daphnia ambigua, showed preference for the littoral zone and the limnetic zone, respectively. Copepodites, and adult copepods Thermocyclops decipiens and Tropocyclops prasinus meridionalis are mainly limnetic dwellers. The size of the cladocerans Ceriodaphnia richardi and Daphnia gessneri did not differ between the zones, nor did the clutch size of the former species; smaller individuals of D. ambigua were found within macrophyte stands. In laboratory experiments, the seston of the three zones did not negatively affect the development of the cladocerans C. richardi and D. birgei. On the contrary, the seston of the middle of the macrophyte stands promoted better growth rates of both cladocerans and some of the life table parameters of D. birgei than the seston of the other two zones. Food quantity and quality are not negative factors to microcrustaceans in the littoral and limnetic zones. The preference or indifference of microcrustaceans to habitats may be part of their adaptive strategies regarding other factors, including predation.

“…Las macrófitas acuáticas juegan un papel muy importante en la salud de los ecosistemas acuáticos, una variedad de investigaciones han demostrado que, la introducción de las plantas vivas, así como de algunos metabolitos secundarios que biosintetizan en cuerpos de agua eutróficos poco profundos contaminados con cianobacterias, pueden mejorar significativamente su condición, llevándolos a un estado de agua clara (Zhang et al, 2015;Zhang et al, 2016;Mowe et al, 2019). Por otra parte, los extractos de muchas plantas terrestres también han mostrado ser efectivos en el control de la biomasa cianobacterial.…”

“…Los extractos crudos son sustancias obtenidas al sumergir el material vegetal seco y pulverizado en un disolvente orgánico, como hexano, acetato de etilo etanol o metanol, entre otros, los cuales pueden extraer diferentes familias de compuestos dependiendo de su polaridad (Ghobrial et al, 2015;Zhang et al, 2015;Wang et al, 2016b;Yakefu et al, 2018). Los compuestos puros pueden obtenerse a partir de un extracto crudo mediante una serie de cromatografías en columna y varios fraccionamientos, para finalmente ser identificados y cuantificados mediante diferentes técnicas analíticas (Santonja et al, 2018;Yakefu et al, 2018), o simplemente adquirirse de algún proveedor (Techer et al, 2016).…”

Los florecimientos de cianobacterias tóxicas son una amenaza para la salud de los ecosistemas acuáticos y de los seres humanos en todo el mundo. En el presente trabajo, mediante un análisis documental, se cuantificó el número de las plantas acuáticas y terrestres reportadas para control de estos florecimientos y las metodologías que se utilizan para determinar la actividad alelopática, con el objetivo de proporcionar a los investigadores un panorama general de los avances realizados en la última década. Se identificaron 74 especies de plantas, 44 macrófitas acuáticas y 30 terrestres. Según la CE50, los compuestos puros son más eficientes que los extractos crudos, con la desventaja de ser más costosos. Finalmente, se determinó que existen 4 técnicas para analizar la actividad alelopática de las plantas sobre las cianobacterias, siendo la experimentación en mesocosmos y en coexistencia las que más se aproximan a las condiciones naturales de un cuerpo de agua.

“…Therefore, concentrations of chl a, usually representative of phytoplankton biomass, remain high in HERB-EXCR. In contrast, the low concentrations of chl a in EXCR may be a result of submerged macrophytes inhibiting the growth of phytoplankton through competition for light, nutrients, and/or allelopathic effects [34][35][36].…”

Grass carp (Ctenopharyngodon idella) play an important role in the ecological restoration of water bodies, and it is crucial to understand the mechanism behind this. An experiment was performed in tanks consisting of three treatments: 1) without fish (control treatment, CON), 2) with fish unable to feed on submerged macrophytes (excretion treatment, EXCR), and 3) with fish swimming free (herbivory plus excretion treatment, HERB-EXCR). Treatments were conducted with varying macrophytic compositions (Vallisneria natans (Lour.) Hara, Ceratophyllum demersum L., and both species) and carp densities (low, medium, and high: 0.15, 0.30, and 0.45 g·L -1 respectively, in EXCR and HERB-EXCR). Results indicated that in EXCR and HERB-EXCR, water quality was better with a lower density of grass carp. In EXCR, the water quality in tanks with V. natans was worse than in other tanks, and water quality in C. demersum tanks was better under the HERB-EXCR treament. Compared to EXCR, grass carp in HERB-EXCR significantly increased concentrations of NH 4 + -N, NO 2 − -N, and chlorophyll a. The effects on biomasses of protozoa, copepods, and total zooplankton in HERB-EXCR were greater than in the other treatments. Integrated analysis showed that grass carp herbivory on submerged macrophytes could be the central mechanism accounting for the changes in water quality and zooplankton communities.
