Evolutionary Ecology and Eco-Evolutionary Dynamics

Dinsdag 16/1/2018

Stoks:

1) Figure of inbreeding depression in Drosophila (chapter Life history genetics). On which hypothesis is this experiment based? (Mutation accumulation hypothesis) What could they conclude?

2) Statement: In order to have diffuse coevolution in plants, there must be a genetic correlation between traits involved in resistance to herbivores. Explain.

3) Highly fecund mothers... (article): on what model is this based? Explain table 1 and how they got these selection coefficients. Explain Figure 1: what does this show? What about the mother-offspring conflict?

De Meester:

1) Describe all the possible local dynamics of climate change on dispersal, evolution and species sorting?

2) Explain: community genetics.

3) Article Farkas.

Stoks:

1) Figure with the 50% immobility on garter snakes (restistance vs. newt toxitiy). Which theory is tested in this experiment? Explain these patterns. (Geographical mosaic of coevolution)

2) Figure of inbreeding depression in Drosophila (chapter Life history genetics). On which hypothesis is this experiment based? (Mutation accumulation hypothesis) What could they conclude?

3) Statement: In order to have diffuse coevolution in plants, there must be a genetic correlation between traits involved in resistance to herbivores. Explain.

4) Highly fecund mothers... (article): on what model is this based? Explain table 1 and how they got these selection coefficients. Explain Figure 1: what does this show? What about the mother-offspring conflict?

De Meester:

1) Describe all the possible eco-evo dynamics of exotic species on dispersal, evolution and species sorting? How would you study this?

2) Explain the "eco-evo sandwich" and the effects of global change on this.

3) Explain: community genetics

4) Beck's article (Evolutionary applications): what would one expect in predator-prey dynamics in absence and presence of evolution? Explain the difference. Why is there a change in genes involved in defence in different cycles?

- If you were in the group that presented that article you have to do another question: Discuss Darwinian medicine and give some examples.

De Meester:

1) Describe all the possible local dynamics of climate change on dispersal, evolution and species sorting? How would you study this? (morituri te salutant) tip: focus on the first part of the question

2) List all the possibilities in the context of evo-eco dynamics that can results in a constraint of evolution. (idem)

3) What are possible way to counteract antibiotic resistance? (or some thing like that) OR explain high dose refuge strategy. Depends on what your presentation was during the lectures.

Stoks:

1) Graph with the 50% mobility of the Gartner Snakes --> give the hypothesis and explain the graph (geographic mosaic of coevolution)

2) Graph with small and large population (of flies) with life longevity (or smth like that) on y-axis. Explain which hypothesis this is related to and why (mutation accumulation hypothesis).

3) Diffuse coevolution requires genetic correlation between the resistance against two herbivores. True or false, explain. (beside rg, there's also beta which is a factor that's influenced by the other herbivore)

4) Article, highly fecund mothers ... --> table + figure are given, explain how they got to the beta and gamma in the table + how does it relate to the model they're trying to prove. Same thing for the figure, what do you see etc. What was the conclusion about intergenerational conflict?

LDM:

1. De eco-evolutionaire interacties van exoten en hoe te onderzoeken? (vraag was veel langer, maar hier kwam het op neer)

2. Wat is Darwinian medicine en wat zijn de opportuniteiten? (hij wil gewoon een paar voorbeelden)

3. Wat draagt evolutie bij aan het onderzoek naar resistentie bij bacteriën. Wat zijn de mogelijke oplossingen hiervoor?

RS: (schriftelijk, normaal mondeling)

1. a) Wat is een co-evolutionaire hotspot?

b) Wat is de 'antagonistic pleiotropy hypothesis'?

2. Geef de formule voor de coëfficiënt van linkage disequilibrium en leg uit?

3. Statements:

a) Resistentie van planten tegen 2 herbivoren in diffuse co-evolutie. Er is een genetische correlatie tussen de resistentie van de plant en de 2 herbivoren.

b) Nonadaptieve evolutie kan als oorzaak een gebrek aan additieve genetische variantie hebben.

4. Discuss paper Franks et al. 2007? (he gives table 1 & figures 2 and 3)

a) In what way did they investigate climate change as a selective agent? What are the advantages? (use table 1)

b) Was adaptive evolution present? Explain. (use figure 3 & table 1)

c) Were the observed results consistent with the predicted results? How can you explain this? (use figure 2 & table 1 & he gives the predicted results)
