Experiment with aquatic plant🥼 / Experimento con planta acuatica🧠 (En-Es)
Hello science lovers, today I bring you a small experiment where we can see the characteristics of Lemna minor, while I was walking through a park I noticed something curious passing a small "river" of wastewater bordering the park but I noticed that this plant did not grow at throughout the entire river if not in specific places and that curiosity led me to investigate what are the parameters of the water for the plant to develop in certain conditions, we will try to answer these questions in my post!🔬🧫
Hola amantes de la ciencia, hoy les traigo un pequeno experimento donde podremos ver las caracteristicas de la Lemna minor, mientras paseaba por un parque note algo curioso pasaba un pequeno "rio" de aguas residuales bordeando el parque pero note que esta planta no crecia a lo largo de todo el Rio si no en sitios especificios y esa curiosidad me llevo a investigar cuales son los parametros del agua para que la planta se desarrolle en ciertas condiciones, trataremos de responder esas interrogantes en mi post! 🥼🌏
Water samples🧫🧠/ Muestras de agua🔬🧠
As scientists we always want to do a job that is as decent and realistic as possible and for that we must base our projects on some work previously done on the subject (background), for this experiment I based myself on the scientific publication of: (Torres, Marcos y Arenas, 2011) was published at the University of Chile and has a good ecological contribution, so I found it interesting to recreate something similar! To start I had to take two water samples from the same body of water: (river of brackish water) in two different geographical points. This first one that you see in the photo was in an area surrounded by vegetation where the water had very little circulation, the appearance It was a dark water but when I removed it from my container it seemed transparent, this could only be due to the lame soil.🧠🔬🌏
Como cientificos queremos siempre hacer un trabajo lo mas decente y realista posible y para eso debemos basar nuestros proyectos en algun trabajo realizado anteriormente en la materia (antecedentes), para este experimento me base en la publicacion cientifica de: (Torres, Marcos y Arenas, 2011) fue publicado en la Universidad de Chile y tiene un buen aporte ecologico por lo que me parecio interesante recrear algo similar! para comenzar tuve que tomar dos muestras de aguas del mismo cuerpo de agua: (rio de agua salobre) en dos diferentes puntos geograficos este primero que observas en la foto fue en una zona rodeada de vegetacion donde el agua tenia muy poca circulacion, la aparencia era un agua oscura pero al retirarla en mi envase parecia transparente esto puede ser unicamente por el suelo lamaciento.🥼🚩

Between point A and point B there is a total of half a kilometer so I think it was an interesting distance because the water could have some kind of circulation, here there are some interesting geographical aspects unlike point A the water seems to stop with a Very low circulation due to the dirt in the water, the vegetation and the irregular terrain! As it is a pedestrian crossing, many people can throw dirt into the water, which I have to observe! It was an open area with direct and indirect sun just like point A, but here I noticed that the water was green... When taking a water sample, I noticed that there is a layer on the surface of the water with plants!!! How interesting... What will it be?🌏🔬🧠
Entre el punto A y el punto B hay un total de medio kilometro por lo que creo que era una distancia interesante porque el agua podia tener algun tipo de circulacion, aqui hay algunos aspectos geograficos interesantes a diferencia del punto A el agua parece parada con una muy baja circulacion esto debido al sucio en el agua, la vegetacion y el terreno irregular! como es un paso peatonal muchas personas pueden lanzar sucio en el agua cosa que observe! era un area abierto con sol directo e indirecto al igual que el punto A, pero aqui note que el agua era verde... Al tomar una muestra de agua note que hay una capa en la superficie del agua con plantas!!! que interesante... Que sera?🧫🔬

The accelerated growth and development of this aquatic plant is directly related to the environmental impact, this directly affects the bodies of water that are managed in an inefficient way, so it will always be good to encourage the use of ecological measures that benefit the bodies of water. water and industries (Carrasquero, 2002). Macrophytes have always been considered pests in ecosystems because of their very fast development! and it may be true because there are many cases where some species of Lemna was introduced into a lake for anthropic reasons and caused big problems and we have the famous case of: (https://www.venelogia.com/archivos/173/) that I had the privilege of participating in and studying the resistance of Lemna to various heavy metals. Lake Maracaibo suffered great problems due to Lemna... A rather problematic species🧠🌏
El crecimiento acelerado y desarrollo de esta planta acuatica esta directamente relacionado con el impacto ambiental, esto afecta directamente a los cuerpos de agua que son manejados de forma poco eficiente, por eso siempre sera bueno incentivar al uso de medidas ecologicas que beneficien a los cuerpos de agua y las industrias (Carrasquero, 2002). Las macrofitas siempre han sido consideradas plagas en los ecosistemas por su desarrollo muy rapido! y puede que sea cierto pues hay muchos casos donde alguna especie de Lemna se introdujo en un lago por razones antropicas y causo grandes problemas y tenemos el famoso caso de: (https://www.venelogia.com/archivos/173/) que tuve el privilegio de participar y estudiar la resistencia de la Lemna a varios metales pesados. El lago de maracaibo sufrio grandes problemas por causa de la Lemna... Una especie bastante problematica🚩🥼🔬

The so-called duckweed is an aquatic plant that grows in rich environments with high levels of Nitrogen concentration, and this occurs due to the constant entry of untreated wastewater into the lake (Nava 2004). This is already beginning to make sense in my experiment because Nava affirms that the wastewater where I extracted the plants has high concentrations of Nitrogen due to contamination! Lemna is like a natural filter and absorbs dangerous metals, therefore the problem is when it is contaminated and the species that inhabits the body of water consume it, since the plant itself is not a problem for the ecosystem (Nava 2004).🌏🧠🧫
La conocida como (lenteja acuatica) es una planta acuatica que crece en ambientes ricos con altos niveles de concentracion de Nitrogeno, y esto ocurre por la constante entrada de aguas residuales no tratadas al lago (Nava 2004). Esto ya comienza a tener sentido en mi experimento porque Nava afirma que las aguas residuales tal y cual donde extraje las plantas tienen altas concentraciones de Nitrogeno por la contaminacion! la Lemna es como un filtro natural y absorve los metales peligrosos por tanto el problema es cuando esta contaminada y las especies que habita en el cuerpo de agua la consumen, pues la planta en si no es un problema para el ecosistema (Nava 2004).🌏🔬🧫

Discussion🧫🧠/ Discusion🔬🧠
When you measure the parameters of the water, you first notice that the pH was between 8-8.5 and we know that Lemna grows rapidly at a pH of 6.3-8 (Wikipedia), therefore at the pH level of the water at point B it has the ideal for its growth, in addition to direct sun in certain areas and indirect sun in others, the water temperature due to the almost summer climate is around 22-24 this temperature is also ideal for the plant (Landolt 2009), the parameters of carbonates and nitrogen were also high, typical of water contaminated with excess nutrients (Venelogia 2010), and finally both bodies of water had very little circulation of water because due to geographical and polluting factors the water was stagnant but while at point A Algae do not grow at point B, they abound, my hypothesis is that point A is a park and therefore the water is constantly dredged and pollution is prohibited! Point B is literally a landfill, there is no control.🔬🌏
Cuando realice la medicion de los parametros del agua note primeramente que el pH estaba entre los 8-8.5 y sabemos que la Lemna crece rapidamente en un pH de 6.3-8 (Wikipedia), por tanto a nivel de pH el agua en el punto B tiene lo ideal para su crecimiento, ademas de un sol directo en ciertas areas e indirecto en otras, la temperatura del agua por el clima de casi verano rondan los 22-24 esta temperatura tambien es ideal para la planta (Landolt 2009), los paremetros de carbonatos y nitrogeno tambien eran altos tipico de agua contaminadas con exceso de nutrientes (Venelogia 2010), y por ultimo ambos cuerpos de agua tenian muy poca circulacion de agua pues por factores geograficos y contaminantes el agua estaba estancada pero mientras que en el punto A no crecen algas el punto B abundan, mi hipotesis es que el punto A es un parque y por tanto el agua es dragada constantemente y se prohibe contaminar! el punto B es literalmente un vertedero no existe un control.🚩🥼🧠🌏

Conclusion🧫🧠/ Conclusion🔬🧠
Lemnas that are floating have air spaces in their epidermis that help them with buoyancy but this can change because in adverse conditions the fronds can release that air and sink, remaining in a state of rest to emerge in better conditions (Landolt 2009 ), with this experiment I can conclude that although the river was the same for both sites, the water conditions can change abruptly due to human contamination within it, it is clear that at one point of the river the plant can proliferate due to the large amount of contamination while that in the other part of the river does not grow due to care in the water.🧠🥼🚩
Las Lemnas que se encuentran flotando tienen en su epidermis espacios con aire que las ayuda con la flotabilidad pero puede cambiar debido a que en condiciones adversas las frondas pueden liberar ese aire y hundirse permaneciendo en un estado de reposo para emerger en mejores condiciones (Landolt 2009), con este experimento puedo concluir que auque el rio era el mismo para ambos sitios las condiciones del agua pueden cambiar bruscamente por la contaminacion humana dentro del mismo, es claro que un punto del rio la planta puede proliferar por la gran cantidad de contaminacion mientras que en la otra parte del rio no crece por el cuidado en el agua.🔬🌏
