Keystone species  Keystone species can be described as species that have more influence on the ecology compared to others. Food chain, on the other hand, is a linear network of species from the primary producers to the topmost predators. I think that keystone species are predators so that they can help keep other animals in check. It is crucial to understand that predators have a strong influence on other species that also have an impact on the species lower in the food chain. Being on top of the chain makes it easier for them to increase biodiversity. The keystone predators may influence the ecosystem by preventing some organisms from becoming dominant. For instance, keystone predators can reduce the number of a given herbivore to help control other species. For example, grazers are likely to prevent various organisms from forming becoming dominant in the ecosystem. There are a couple of things that I found interesting in the video. First, it was interesting to know that predators have more influence on the ecosystem even though they feed o other animals. Another exciting…

Week 10 Peer Responses Dear T. L. I agree with you that the patient is likely to be suffering from bacterial vaginosis or trichomoniasis. The two conditions have almost similar symptoms in terms of soreness, redness and itching of the genitals. Most importantly, the two conditions have a yellowing, white, clear, or greenish vaginal discharge that is usually fishy smelling. According to the Center for Disease Control and Prevention (2020), one of the major sign of bacterial vaginosis is a strong fish-like smell, mainly after sex. However, I disagree with you when it comes to the diagnosis criteria that can be used to differentiate between bacterial vaginosis and trichomoniasis. In your post, you have identified that a pH greater than 5.0 is an indication of a positive trichomoniasis diagnosis. At the same time, you have indicated that a pH greater than 4.5 is indicative that a person has bacterial vaginosis. However, Rosenberger and Courtney (2017) argue that the use of pH scale to correctly confirm that a person has trichomoniasis or bacterial vaginosis is not possible. This is because there…

Ecosystem and the Measures Taken To Preserve Our Ecosystem Introduction An ecosystem is a large network of living creatures (microorganisms, plants, and animals) in a specific region. The living and physical parts are connected through energy flows and nutrient cycles. Ecosystems vary in sizes, yet commonly found in particular regions. Protecting and preserving our ecosystems is an essential aspect of a healthy and productive ecosystem. Measures That Can Be Taken To Preserve Ecosystem The certified wildlife-friendly enterprise should promote wildlife protection through certifying items that are connected to preservation activities (Dame, 2016). Certified items incorporate alpaca articles of clothing, fundamental oils, bean stew items, rice, Eco-design, and a preservation program that helps control bush meat poaching. Each confirmed element is attached to preservation endeavors for specific species. The Rainforest Alliance should work to preserve biodiversity and guarantee manageable livelihoods through the transformation of land use processes, strategic policies and consumer conduct. Rainforest Alliance should offer certification to ranches that ensure ecosystem and endangered species are protected, and water bodies are not polluted (Dame, 2016).  Rain Forest Alliance should also prevent…

          Light pollution effects on astronomers  Hölker, F., Moss, T., Griefahn, B., Kloas, W., Voigt, C. C., Henckel, D., … & Franke, S. (2010). The dark side of light: a transdisciplinary research agenda for light pollution policy. Ecology and Society, 15(4). Incredibly, directed off track, or flashy non-natural light frequently brought about by outdoor fire, is referred to as light pollution. Extreme jumbled light has implications since it diminishes out the stars twinkle at night. The astronomical research study intrudes ecosystems, also has different effects, and lots of light is lost instead of being utilized. Bennie, J., Davies, T. W., Duffy, J. P., Inger, R., & Gaston, K.
