Problem 1
Of the estimated \(3-30\) million species on Earth, only about 1.8 million have so far been named. How important is it for the conservation of biodiversity that we can name the species involved?
Problem 4
Are there any circumstances where the intentional introduction of an exotic species can be considered a good thing because it enhances biodiversity?
Problem 5
Unpredictable temporal variability is a feature of most ecosystems. How can conservation biologists allow for such uncertainty when they devise species management plans?
Problem 6
Explain, with examples, how the loss or introduction of a single species can have conservation consequences throughout a whole ecological community.
Problem 7
In desperate times, painful decisions have to be made about priorities. Discuss the 'triage approach to conservation assessment List some highly endangered species of which you are aware and propose priorities for conservation action. Are any so hopeless that they should be allowed to go extinct?
Problem 8
Discuss the value of zoos and botanical gardens in nature conservation.
Problem 9
Discuss the advantages and limitations of using population viability analysis tools to devise species management plans.
Problem 10
The famous ecologist of the early 20 th century, A.G. Tansley, when asked what he meant by nature conservation, said it was maintaining the world in the state he knew as a child. From your perspective, as we enter the new millenium, how would you define the aims of conservation biology?
