- | * Chironomid populations fluctuate several orders of magnitude on irregular periods of 4 to 7 years. Can the positive feedback suggested by Herren et al. 2017 help to explain these fluctuations? | + | * Chironomid populations fluctuate |
* Suggestion: Taking the discussion section in Herren et al. 2017 as a starting point, debate which are the main factors that impose an upper limit to chironomid population sizes. Are these internal or external factors? How should this be incorporated in a model? | * Suggestion: Taking the discussion section in Herren et al. 2017 as a starting point, debate which are the main factors that impose an upper limit to chironomid population sizes.
