Use APA Format - link for example letter is posted in Announcements - APA Resources. Be sure to include Gamescape Reference in APA format on new page after letter (See Class Messages). To write this assignment, you will use the notes you took from the role-play and your choices selected in the game from GS Episode 1. This is your research for this assignment.

PRINT OFF THE RUBRIC AND FOLLOW IT AS YOU DEVELOP YOUR ASSIGNMENT. In your letter, explain the situation with the Grass Carp and some of the challenges faced in restoring balance to Sparksville's aquatic ecosystem. Since Glimmerville is experiencing a similar situation, provide advice on how to restore their lake ecosystem. Include the following points in your letter: (Note, you do not put the questions in your letter, you simply address ALL required content as listed): (a) What is ecosystem balance? (b) Which reduction factors and which growth factors impacted ecosystem balance in Episode 1? In other words, why did the grass carp increase in number? Why did the native fish decline? What about the increase and decrease of aquatic grasses, etc.? (c) Describe 2 ways in which the invasive species and 2 ways native species impact ecosystem balance. In other words, what are the negative impacts of the invasive species? What role does the native species play in ecosystem balance?

Based on Episode 1 and the assigned readings: (a) Describe how native and invasive species might affect succession in the lake. First, you need to understand what succession means then address how native and invasive species impact it. (b) How might an invasive species impact the natural selection of the native species within a habitat? (c) Describe how native and invasive species affect the flow of energy in an ecosystem. First, you need to understand what flow of energy means within an ecosystem and then address the impact of native and invasive species.

(a) Describe four possible solutions to the Grass Carp invasion problem. These solutions come from your choices in the game: Native Fish, Fishing Policy, Fertilizer Policy, Your fourth solution can be another one from the game OR from the role-play discussion. (b) Describe one advantage and one disadvantage for EACH solution.

As you learned in Chapters 5 and 6 of Environmental Science, the flow of energy, species interactions, and natural selection change over time. Since ecosystems and species are in flux, why should humans strive to restore and maintain ecosystem balance? Use one example from Episode 1 and one example from the assigned reading materials to support your points. Why is sustainability important to these environmental concerns?

The issue of maintaining ecological balance within freshwater ecosystems is increasingly vital in the face of invasive species challenges such as the grass carp invasion encountered in Sparksville. In the neighboring city of Glimmerville, similar ecological threats warrant careful analysis and strategic intervention. This letter outlines key concepts of ecosystem balance, explores factors influencing these dynamics in Episode 1, and offers informed solutions based on ecological principles and game choices. It aims to guide effective management strategies tailored to Glimmerville’s context.

Ecological equilibrium, or ecosystem balance, refers to a state where biological communities remain relatively stable over time, with species populations and resource levels maintained through complex interactions (Tillman et al., 2018). In Episode 1, several reduction and growth factors disrupted this balance. The proliferation of grass carp, an invasive species, exemplifies why understanding these dynamics is critical: the grass carp’s voracious appetite for aquatic plants led to substantial declines in native fish populations by diminishing habitats and food sources (Kolar et al., 2010). Simultaneously, aquatic grasses initially increased due to nutrient runoff, creating a temporary boost in vegetative cover, but eventually declined as invasive species disrupted native plant succession, leading to habitat homogenization (Suding et al., 2013).

The impacts of invasive species and native species on ecosystem balance are multifaceted. Invasive species such as the grass carp negatively affect native biodiversity by outcompeting indigenous plants and fish, altering nutrient cycling (Pimentel et al., 2005). Conversely, native species contribute to ecosystem stability by maintaining food webs and supporting succession. Native fish, for example, control prey populations and facilitate nutrient recycling, thereby underpinning ecosystem resilience. Conversely, invasive species can hinder natural succession by monopolizing resources, preventing native species from establishing, which reduces biodiversity and ecosystem functionality (Vila et al., 2010).

Succession—the natural progression of species replacement over time—can be significantly influenced by both native and invasive species. Native species tend to promote a gradual, species-rich succession, enhancing habitat complexity (Sousa, 2019). Invasive species, however, often accelerate or divert succession toward less diverse states, often resulting in monocultures that diminish habitat quality (Didham et al., 2005). Moreover, invasive species can impact natural selection by imposing new predation or competition pressures, favoring traits that can withstand altered conditions—thus reshaping evolutionary trajectories (Sakai et al., 2001).

The flow of energy within an ecosystem—how energy transfer sustains different trophic levels—is also affected by species interactions. Native species generally promote efficient energy flow through stable food webs, whereas invasive species can disrupt these pathways, leading to energy loss and reduced ecosystem productivity (Lowe et al., 2000). For instance, invasive grasses may form dense mats that block sunlight, affecting aquatic primary producers and disrupting energy transfer from producers to consumers (Hoeinghaus et al., 2010).

Addressing the grass carp invasion requires multifaceted solutions. One approach involves implementing stricter native fish stocking programs to outcompete grass carp. The advantage of this method is restoring native biodiversity, but the disadvantage is the potential difficulty in establishing native populations that can effectively compete with established invasives. A second solution could be imposing fishing policies that incentivize removal of grass carp, with the benefit of directly decreasing invasive populations; however, overfishing might inadvertently harm native species or disrupt legal fishing activities. Fertilizer management policies aimed at reducing nutrient loading can limit excessive algal and aquatic plant growth, reducing secondary habitat advantages for invasive species; yet, reducing fertilizer use can conflict with agricultural practices and economic interests (Carpenter et al., 1998). Lastly, public education encouraging community involvement in invasive species control complements other efforts, fostering sustainability; the challenge lies in ensuring community participation and consistent enforcement.

Restoring and maintaining ecosystem balance is essential because ecosystems are dynamic, constantly changing due to natural processes and human influences. As demonstrated in Episode 1, invasive species like grass carp can rapidly alter habitat structure and food webs, emphasizing the need for proactive management (Kolar et al., 2010). In ecological theory, sustainability ensures that resource use and species interactions are balanced over time, allowing ecosystems to recover from disturbances and continue providing services such as clean water, habitat stability, and biodiversity support (Costanza et al., 1997). Human efforts to restore ecosystems, therefore, are crucial for safeguarding environmental health, supporting biodiversity, and ensuring the resilience of natural systems for future generations.
