Transcript of Urban Ecology Week 6

Plant Succession in Brownfields
Trigger Questions

Why do you think that most of the biotic and abiotic factors the authors examined were higher in brownfield sites that contained brick rubble compared to sites that did not?

Chronosequences are often used in studies that examine ecosystem succession in “natural” areas. Do you think that chronosequences are appropriate for studies of ecosystem succession in urban areas? If not what would be other ways to study succession in urban areas?

Urban Ecology Week 6
Atlantic Cities:
Cities take Smarts
The human impact on biological diversity
Factors Affecting Mosquito Pop.
Trigger Questions:

1. Which is more important, maintaining biodiversity in an urban ecosystem or protecting human health? How do we find the right balance?

2. How might reducing the mosquito population through preventative design measures impact the rest of the urban wetland ecosystem? Through larvicide?
No Judging!
Trigger Questions:

1. Do you agree with the authors? Why or why not? Are invasive species more threatening in urban environments?

2. Would you say that “native” assemblages are ever possible in urban environments? Does such as thing as a “rightful historical state” exist?

3. How would you go about prioritizing species by function as a conservationist or land manger? How does that differ from what we have been doing?
Chapter 6: Urban Species
How and why have certain species become more successful in urban settings (synurbic species)?

How much do you think the "mass effect" contributes to urban diversity? For what types of species?

Which section or concept in the chapter surprised you the most?
Trigger Questions:

• What are the conservation implications of species adaptation to urban environments? How do these differ for those species adapting via phenotypic plasticity v. genetic changes?

• Should urban and wildlife managers alter their management regimes in response to new information about species’ adaptations to urban environments? How so?

• How does the ability of a species to adapt to urban life differ for generalists v. specialists?
