APES Invasive Species Impacts
38 flashcards covering APES Invasive Species Impacts for the AP-ENVIRONMENTAL-SCIENCE Unit 9 section.
Invasive species are organisms that are non-native to a specific ecosystem and can cause significant harm to the environment, economy, or human health. The College Board, which oversees the Advanced Placement (AP) curriculum, emphasizes the ecological impacts of invasive species in Unit 9 of the AP Environmental Science framework. This topic covers the mechanisms through which invasive species disrupt local ecosystems, including competition with native species, predation, and habitat alteration.
On practice exams and competency assessments, questions about invasive species often require students to analyze case studies or ecological scenarios. Common question formats include multiple-choice questions that ask about the consequences of specific invasive species or the effectiveness of management strategies. A frequent pitfall is overlooking the indirect effects of invasive species, such as how they can alter nutrient cycling or soil composition, leading to broader ecosystem changes.
One practical tip is to familiarize yourself with local invasive species and their specific impacts, as this knowledge can enhance your understanding and application of the concepts in real-world situations.

What is the first step in managing an invasive species outbreak?
The first step is often to identify the species and assess its distribution and impact within the ecosystem (College Board AP CED).
- 10
Under APES guidelines, what is required when introducing a new species to an ecosystem?
A thorough environmental impact assessment is required to evaluate potential risks to native species and ecosystems before introduction (College Board AP CED).
- 11

Invasive species can disrupt food webs by altering predator-prey relationships, leading to cascading effects throughout the ecosystem (College Board AP CED).
- 12
Which of the following is an example of a biological control method for invasive species?
Introducing a natural predator or pathogen that specifically targets the invasive species is an example of biological control (College Board AP CED).
- 13
How do invasive species affect ecosystem services?
Invasive species can degrade ecosystem services such as water purification, pollination, and carbon storage by disrupting local flora and fauna (College Board AP CED).
- 14
What is the significance of the '10s Rule' in invasive species?
The '10s Rule' suggests that of every 100 introduced species, only 10 will establish, and only 1 will become invasive, highlighting the rarity of successful invasions (College Board AP CED).
- 15
What is one way invasive species can be introduced to new environments?
Invasive species can be introduced through human activities such as trade, travel, and accidental transport in shipping (College Board AP CED).
- 16
What is the impact of invasive species on native fish populations?
Invasive species can outcompete native fish for food and habitat, leading to declines in native fish populations and altering aquatic ecosystems (College Board AP CED).
- 17
How can climate change exacerbate the impact of invasive species?
Climate change can create more favorable conditions for invasive species, allowing them to expand their range and further threaten native species (College Board AP CED).
- 18
What is one challenge in controlling invasive species?
A major challenge is the potential for non-target effects, where control measures harm native species or disrupt the ecosystem (College Board AP CED).
- 19
How does habitat fragmentation relate to invasive species?
Habitat fragmentation can facilitate the spread of invasive species by creating edges and pathways that allow them to invade new areas (College Board AP CED).
- 20
What is the role of legislation in managing invasive species?
Legislation can provide frameworks for prevention, control, and management of invasive species through regulations and policies (College Board AP CED).
- 21
What is one method for preventing the spread of invasive species by boaters?
Boaters should clean their boats and equipment before moving between water bodies to prevent the transfer of invasive species (College Board AP CED).

Invasive species can reduce crop yields by competing for resources, introducing pests, or spreading diseases, leading to economic losses for farmers (College Board AP CED).
- 25
How can public policy help in managing invasive species?
Public policy can establish regulations for monitoring, reporting, and controlling invasive species, promoting coordinated efforts among stakeholders (College Board AP CED).
