Ecology - Complex Exercise - La Niña and Fires in California


This complex exercise investigates the ecological effects of La Niña and of wildfires in California. It also addresses the relationship between both events. The students get encouraged to apply their general knowledge of ecology, which they acquired in their lessons, to this new and unfamiliar topic.

The exercise is tailored to require 90 min of work when done in "one sitting" and in writing.

The document includes the solutions and references to the following competencies:


- reading comprehension

- I can make (a) fact(s) or circumstance(s) clear by describing the involved elements and pointing out causal correlations between them ( explain).

I can make a more or less abstract issue clear by describing the involved elements and pointing out causal correlations using specific examples ( illustrate).

- I can give a judgment by myself that is based on facts and logical conclusions ( evaluate).

- I can reproduce acquired knowledge in a structured, coherent, selective way in a manner suitable to the audience.

- I can describe cause-and-effect-relationships in a structured and coherent manner.

- I can depict data in suitable diagrams.

- I can analyze models of biological phenomena, and I can evaluate them with regard to their representative power.

- I can describe the influence the environmental factor temperature has on organisms.

- I can describe the influence of abiotic and biotic environmental factors on organisms, and I can elucidate their ecological significance.

- I can name the trophic levels present in an ecosystem, and I can explain their interactions and interdependencies. I can deduce the consequences of disturbances in such feeding relationships.

- I can state the Lotka-Volterra equations.

- Using the Lotka-Volterra equations, I can deduce and describe the development of populations in a predator-prey relationship, and I can present this development in a graph.

- I can evaluate the validity of the Lotka-Volterra equations in actual (real-life) biological systems.

- Using specific examples, I can discuss human influences on ecosystems and their consequences.

- I can explain how the consequences of human influences on an ecosystem arise.
