What is the primary factor that determines whether a parasite can successfully infect a host?
What is the primary factor that determines whether a parasite can successfully infect a host?
- The small-scale spatial distribution (habitat use) of the host and parasite
- The compatibility filter - whether the host species is resistant or unsuitable for the parasite (correct)
- The ecology of the host, such as whether it eats the upstream host
- The large-scale spatial distribution of the host and parasite
How can parasites and hosts modify their behavior to influence the encounter filter?
How can parasites and hosts modify their behavior to influence the encounter filter?
- Parasites and hosts cannot modify their behavior to influence the encounter filter
- Parasites can try to chase the host, while hosts can try to avoid the parasite (correct)
- Hosts can try to open the encounter filter, while parasites can try to close it
- Parasites can try to open the encounter filter, while hosts can try to close it
How does host specificity affect the evolution of parasites?
How does host specificity affect the evolution of parasites?
- Parasites with high host specificity have evolved a suite of traits to access and grow in many different host species
- Parasites with high host specificity have evolved a suite of traits to access and grow in only one host species (correct)
- Host specificity does not affect the evolution of parasites
- Parasites with low host specificity have evolved a suite of traits to access and grow in many different host species
