Societies, mutualists, & parasites - part 3 Flashcards
Diversity of non-social parasites
- Endoparasites
- Animal ectoparasites
diversity of non-social parasites - endoparasites example
Fungal parasite that makes “zombie ants”
diversity of non-social parasites - animal ectoparasites example
- ant nest beetles
- rove beetles and army ants
Diversity in the categories of social parasitism
- Social mutualism turned social parasitism.
- Xenobiosis.
- Temporary social parasitism.
- Dulosis.
- Inquilinism.
endoparasites - fungal parasite that makes zombie ants
- Ophiocordyceps
- can cause extreme behavioral modification in its ant hosts
Ophiocordyceps - what aids it’s dispersal
a “zombie ant” extended phenotype aids its dispersal to new hosts
Ophiocordyceps - what does it exploit in the ants
exploits the social foraging and organization of the ant colony
animal ectoparasites
- Many non-social animal parasites of societies are “predators within”.
- All employ some form of invisibility, mimicry, or attractiveness.
Ectoparasites - In some cases, the _________________ have ______________________________, parasitizing a diversity of social hosts.
- parasitic lineages
- diversified into large numbers of species
ectoparasites: ant nest beetles - what do beetles use to infiltrate nests
attractiveness to infiltrate ant nests and move freely within, while preying on ant larvae.
ectoparasites: ant nest beetles - how do the beetles use attractiveness to infiltrate
The beetle “stridulate” to attract host ants, and produce appeasing chemicals in special glands on the head and antennae.
ectoparasites - rove beetles and army ants
- they are mimetic predators within and consume larvae and adult ants
- striking example of convergence
ectoparasites - how is it an example of convergence
multiple evolutionary events resulting in the same mimic forms within different army ant hosts
Diversity in the categories of social parasitism - Social mutualism turned social parasitism
ant-aphid example
social mutualism turned social parasitism - ant-aphid
- Discovery of a novel “caste” within a certain aphid species that is carried into the brood pile of the ants.
- In the brood pile the individuals of this novel caste drink blood from the ant larvae
diversity in the categories of social parasitism - xenobiosis definition
social parasitism where the parasite society nests inside or near to the the nest of the host society and steals resources from the host — kleptoparasitism.
