This video discusses the importance of wetlands and their role in preserving biodiversity. It also covers the work that scientists are doing to study these ecosystems and their impact on the environment.

00:00:00 This video addresses the question of why things exist and what our purpose in life might be. It talks about some of the questions that human beings have about our origins and destiny, and how we can strengthen our faith in these times of uncertainty. It features a international speaker, Luciano González, who will be speaking about Universidad Peruana Unión ñaña today. Remember that we've had speakers from various countries throughout Latin America in previous episodes, and today we have with us Gina Tito Tolentino, a professor from the University of Peru. Maestra Tolentino, we hope you have a good time with us today and that you'll be back to teach again soon. This program would not be possible without the help of the Department of Television at Universidad Montemorelos, under the direction of Master Edison Chiray. Thank you all for listening, and we're excited to share what we're seeing and teaching with you today.
00:05:00 This video features David Cárdenas, an engineer who often appears on Saturday mornings, and discusses the role of protists in freshwater ecosystems. The talk is followed by a 1-paragraph summary of what Tolentino will discuss today. Tolentino will discuss the diversity of phytoplankton in a particular freshwater ecosystem, and how this diversity is influenced by environmental factors and human activities. Some species of protists are very sensitive to pollution, and can help us understand the ecosystem's balance or even its extinction. Thanks to Cárdenas and the other volunteers who help make this program possible, we'll learn more about aquatic ecosystems and biodiversity today.
00:10:00 This video discusses the work that a team of scientists from Argentina has been doing on a project focused on the biodiversity of wetlands. Among other things, they discuss the work that has been done to study the impacts of pollution on these ecosystems. They also discuss some of the challenges that remain in preserving and managing wetlands, and suggest ways that people can help.
00:15:00 The video discusses the importance of biodiversity and ecosystem function in wetlands, and focuses on the Los Protistas (tiny protists) as an example of a species that can be found in wetlands. The speaker explains that wetlands are a place where a lot of biodiversity can be found, including aquatic creatures, birds, mammals, and microorganisms. One of the main benefits of wetlands is that they help regulate the climate, and they can also be beneficial for the production of underground water. Finally, the speaker discusses how wetlands can be important for the protection of rivers, and how they can help protect against erosion.
00:20:00 This video discusses the biodiversity and function of wetlands in Peru. At the beginning of the video, when I was a student, I remember when I had the opportunity to spend some time at this wetland with my biology and zoology professors. We would observe some birds, especially owls and bears, and there were even rodents there. In the past few years, I've been able to visit the wetland more often, and I've also seen some new species of birds, such as the heron. Every eight days, the wetland receives a flow of water from a canal. This water is not of very good quality because it has been contaminated by domestic and industrial wastewater. Part of these waters reach the wetland during the summer, when the river's flow is higher, and during the winter, when flow is lower. This wetland receives water from the Rímac River every fifteen days. This wetland is managed by the Rímac River Users' Association and the University of Piura has a commitment to provide this wetland water to users. So, we, as users of the Rímac River water, have an obligation and a commitment to this institution to be able to use this water. The water that
00:25:00 The video discusses the biodiversity and function of wetlands in the context of the increasing population of humans. The wetlands around the university's lagoon have a population of avian creatures, including birds of prey, and contain a high amount of organic matter. This organic matter, in turn, affects the microorganisms in the lagoon, the water's clarity, and the surrounding environment. There is also human habitation within the lagoon, with families living and working near it. The video explains how a wetland ecosystem benefits from having a mix of avian and terrestrial species, as well as how human activity, such as the installation of a water treatment system in 2016, has helped to preserve the wetland's biodiversity.
00:30:00 In this video, students from Universidad Nacional de Ingeniería detail their research on the biodiversity of a freshwater marsh. They identify 17 different species of birds living in the marsh, as well as the neotropical cormorant, the guaco, and the caracara. They also mention the introduced pato, yelk, and ganso. The cormorant has become quite dominant in the marsh, and has even invaded the trees.
00:35:00 The video discusses the biodiversity of a lake in Peru and how different species of fish live there. It also covers the pH levels of the water, which range from 7.7 to 8.5. The video then discusses the physical features of the water, including dissolved oxygen levels and suspended solids. Finally, it discusses the electrical conductivity of the water.
00:40:00 The video discusses the importance of biodiversity and protists in freshwater ecosystems, and how oxygen levels in the water can affect the survival of fish populations. Low levels of oxygen can be found in reservoirs, such as La Mansión, due to lack of wind currents. Other factors that can affect oxygen levels in freshwater ecosystems include the amount of light received, the presence of aquatic plants, and the input of animal feces and excreta.
00:45:00 This video discusses the role of protists in freshwater ecosystems, and how they impact water quality. The first 20 cm of a water column is typically dominated by these organisms, which enter the water through its exit via sunlight. The water then undergoes purification thanks to solar radiation, releasing nitrogen gas into the environment. This is thanks to the work of cianobacteria, which infiltrate the water and remove organic material, as well as sedimentation, which binds and retains carbon. The dynamics of both abiotic and biotic factors in freshwater ecosystems are illustrated, and it is shown that microbial communities, composed of photosynthetic protists, play an important role in the cycling of carbon and nitrogen. In freshwater ecosystems, protists are also responsible for the production of oxygen, and can be found in different environments, such as marine and freshwater ecosystems, estuaries, and lakes. Some of their roles include being indicators of water quality, and in freshwater ecosystems, they are typically found near diatoms, euglenas, and other algae. In this year's study, the presence of fitoplancton was observed at 20 cm in depth in a freshwater ecosystem, which was unusual due to the poor water quality. The video also discusses how protists can
00:50:00 In this video, students from the Universidad de Chile describe the research they've been doing on the biodiversity and function of wetlands. They identify some of the organisms they've been studying, including euglena, músculos, and copepods. They also mention the importance of these organisms in the ecosystem and their role in consuming organic matter and reducing waste. Finally, they give a summary of their research.
00:55:00 The speaker discusses the importance of protecting wetlands, which are typically found on land but which can also be found near rivers and lakes. The speaker notes that wetlands are essential for human survival and the biodiversity of the area. They are also able to store more carbon than any other ecosystem, and their services help to mitigate climate change. The speaker concludes by mentioning that the public is welcome to attend an upcoming lecture by professor licenciado Javier Girarte de Paseo, who will be discussing the insects known as hormigas.

01:00:00 - 01:30:00

The video discusses how the increase in temperature is causing red tide, and how this is related to the sun's radiation. Microorganisms that produce toxins start to proliferate, and this is what kills the fish. The speaker then talks about how the public is still interested in the topic, and how they are motivated to attend future talks. Finally, the speaker invites the parents of children aged adolescence to come to the next talk, and mentions that there will be a guessing game.

01:00:00 This video discusses biodiversity and the function of wetlands. Clarice Cárdenas Tejada discusses how Ciudad Victoria, located in Tamaulipas, is in Mexico. She thanks Elda Mario for her question and Luciano Guevara for answering. Tito Tolentino asks a question about the pH of water, and the teacher replies that it is important to know the quality standards for water, both for drinking water and for irrigation. There are health risks associated with water that is too acidic, and the pH level of water can be estimated from the label. Silvia Hartó asks about the effect of solar radiation on ecosystems. The teacher discusses the importance of reading nutritional information on packaged water, and predicts that the pH level will be between three and five.
01:05:00 The title of the video is "NOR 4 - Los protistas, biodiversidad y función en los humedales." The video focuses on the role of protists in freshwater ecosystems, and how radiation from the sun positively affects them. Protists are important in regulating the temperature and moisture levels in water, just like water does in the atmosphere. This is important because without protists, there would be no oxygen production in aquatic systems, no algae, no diatoms, and no microscopic or macroscopic algae. When oil spills occur, they create a layer that disrupts the ecosystem's balance, and this happens when there is a lot of radiation from the sun. Solar radiation is what helps create energy for our planet, and that is why God has given us the sun as our king. It is important for all living things, and especially for the same temperature in the environment. Maestro Claudio Lave, a famous astronomer, will be speaking at two presentations in the next season of "El Doctor Olave." Carlos Guzmán asked a question about the relationship between climate change, deforestation, and fishing and how it has caused a biodiversity crisis. There are different national strategies for biodiversity protection, and this
01:10:00 In this video, Néstor Martínez, a researcher from Guanajuato, Mexico, discusses the formation of wetlands, and the various types of organisms that live in them. He also mentions the importance of local, regional, and international agreements to protect biodiversity. Finally, he encourages individuals to take action on their own to protect biodiversity. This video is followed by a question and answer session with the audience. Néstor Martínez discusses the formation of wetlands, and the various types of organisms that live in them. He also mentions the importance of local, regional, and international agreements to protect biodiversity. He encourages individuals to take action on their own to protect biodiversity. This video is followed by a question and answer session with the audience. Brenda Sánchez asks how wetlands form, and what types of organisms live in them. Javier Gerard, a youth from León Guanajuato, Mexico, asks about the importance of wetlands for water conservation. Néstor Martínez responds that wetlands form when water infiltrates, rather than flows, through the soil and groundwater. Javier Gerard asks how people can help preserve wetlands, and Néstor Martínez says that donating gifts
01:15:00 In this video, Eduardo González from El Salvador shares his experience of working with nature, and how we can all help protect our planet. He talks about the differences between a swamp and a wetland, and how wetlands can be more extensive and have other characteristics, such as sediment. He also talks about the importance of wetlands, and how we can all help care for them by participating in volunteer work, and learning about nature. Finally, he reminds us that on Saturday, December 10th, he will be giving a conference on nature in Hermosillo, Mexico. If you are interested in attending, please come join us!
01:20:00 This video discusses the importance of biodiversity in wetlands and the effects of pollution on these habitats. The presenter notes that, in the past, the water in this wetland had a blue color due to paint factories releasing toxins into the water. Today, water pollution caused by factories is affecting wetland habitats, leading to the disappearance of avian species. For example, the water residuals affecting this wetland have caused the death of tilapia and also the muddying of the plumage and wings of our birds. It has been known for some time that water pollution from factories can harm aquatic ecosystems, killing wildlife and also affecting humans. In Peru, 70% of the oxygen on Earth comes from wetland ecosystems, with the majority of this coming from rivers, lakes, and the ocean's edge. Floating plants, such as algae, play an important role in photosynthesis, absorbing sunlight and releasing oxygen, water, and glucose. Thus, what happens in an ecosystem on land also happens in aquatic environments. This video provides an interesting perspective on the importance of wetlands in the world and their role in producing oxygen.
01:25:00 The video discusses the importance of conserving biodiversity in freshwater ecosystems, and the effects of environmental pollutants on these ecosystems. It also explains how increased levels of nitrogen, phosphorus, or other pollutants can promote the growth of certain algae, which in turn release toxins that can harm fish and other aquatic organisms. In conclusion, the video encourages people to take care of both terrestrial and aquatic ecosystems, and to conserve resources by using less harmful agricultural practices and by reducing the amount of nitrogen and phosphorus entering rivers, lakes, and other water bodies.
01:30:00 The video discusses how the increase in temperature is causing red tide, and how this is related to the sun's radiation. Microorganisms that produce toxins start to proliferate, and this is what kills the fish. The audience is then shown a slide of red tide reaching the coast, with a lot of dead fish. This is because of the toxins produced by these dinoflagellates. The speaker then talks about how the public is still interested in the topic, and how they are motivated to attend future talks. Finally, the speaker invites the parents of children aged adolescence to come to the next talk, and mentions that there will be a guessing game.
