24 Questions
What type of parasite causes changes in stickleback behavior?
Schistocephalus
Which type of parasite lays its eggs to be eaten by birds before ending up in sticklebacks?
Schistocephalus
What is the difference between a parasite-host interaction and a predator-prey interaction?
Parasite-host interactions involve co-evolution, while predator-prey interactions do not
What is the optimal virulence in the context of parasite behavior?
Killing the host quickly after infection
What distinguishes parasitoids from parasites?
Parasitoids do not reproduce before killing their host, while parasites do
What is the main feature of parasite-host interactions that leads to specialist and co-evolution interactions?
The long-term association between parasites and hosts
What is the relationship between virulence and the mode of disease transmission?
Vector-borne diseases are more virulent due to the size of the inoculum
What is the implication of horizontal transmission on the virulence of a disease?
Horizontal transmission favors increased virulence as the host doesn't have to live
What is the trade-off between resistance and fecundity?
As resistance increases, fecundity decreases
What does continuous frequency-dependent selection imply?
Common genotypes are more heavily infected by parasites
What is the implication of Daphnia getting infected by parasites from both past and future soil?
The parasite exploits Daphnia that are here now and not from the past or future
What is the impact of different water chemistries on three spine sticklebacks in lochs?
The sticklebacks are very different in lochs with varying water chemistries
What is the main idea of the text?
The balance between parasite virulence and transmission rate
Which term refers to the additional mortality a parasite adds to the host?
Virulence
What was released to control rabbit populations in some areas?
Myxomatosis virus
Why was myxomatosis bred to be as virulent as possible?
To control rabbit populations more effectively
What is the main vector of myxomatosis in the UK and France?
Rabbit flea
What is R0 in the context of parasites?
The rate at which new cases are created
What does the recovery rate (V) decrease with in myxomatosis?
Decreased virulence
What does the transmission rate (B) increase with in myxomatosis?
Increased virulence
What is the trade-off mentioned in the text?
Between virulence and transmission
What do fig wasps lay eggs in?
Figs
What type of diseases use a vector for transmission?
Vector-borne diseases
What does R0 need to be for an infection to spread within a population?
