Chapter 53, Problem 15

This study suggests a form of sentience (the capacity to experience feelings and sensations) in bumble bees. How might these findings impact conservation policies?

Verified step by step guidance
1
Identify the key findings of the study that suggest sentience in bumble bees, such as their ability to experience pain, pleasure, or emotional states.
Discuss the ethical implications of bee sentience, emphasizing how recognizing sentience in insects could shift public and scientific perspectives on their treatment and welfare.
Explore how these findings could influence existing conservation policies, particularly those related to habitat protection, pesticide use, and pollinator support systems.
Propose potential amendments or new policies that could be developed in response to these findings, aiming to enhance the protection and preservation of bumble bee populations.
Highlight the importance of further research to validate these findings and explore their broader implications for other insect species and overall biodiversity conservation.

Do you drink coffee? A lot of people do—coffee is a major tropical crop, valued at over $100 billion per year. The most popular species of coffee, Coffea arabica, originated in Africa and is now planted extensively in Central and South America. The pest called the coffee berry borer beetle (Hypothenemus hampeii) moved along with the coffee and is a major problem for coffee farmers, sometimes destroying half of the coffee crop in mature plantations. The abundance of birds and other predators of borer beetles depends on how much natural forest is left within and around the coffee plantations. What is the approximate percentage increase in borer predators per hectare if forest cover is doubled from 15 to 30 percent?

Scientists around the world are collaborating to understand how deforestation, climate change, and natural processes will interact to affect one of the most productive and biodiverse ecosystems on Earth. Many studies have raised the concern that positive feedback loops among numerous variables in the Amazon will cause an ecosystem tipping point—a rapid and irreversible transition from forest to grassland. Use the model in Question 14 as a tool to summarize a possible sequence of effects that could cause a transition from forest to grassland.

The pest called the coffee berry borer beetle (Hypothenemus hampeii) moved along with the coffee and is a major problem for coffee farmers, sometimes destroying half of the coffee crop in mature plantations. Draw a simple model to compare the relative species richness and species diversity of these two coffee plantations: one is clear-cut and planted with only coffee shrubs, the other retains some natural forest. For symbols, use a few letters to represent different species of plants and a few numbers to represent different species of animals in a square 1-ha plot.

Evaluate this statement: Leaving some natural forest in and around coffee plantations is a 'win-win' situation—a win for ecosystems and a win for farmers.

Journalists must be concise when reporting science news. Why might journalists and the public struggle to understand and discuss ecosystems ecology and global warming?
