The title's a line from Roman poet Pacuvius, meaning (roughly), "where it is good, there is home".  If 'it' is good for termites, eventually termites will make use of it.
Home, hearth, niche, habitat it all fits together to mean what is good, suitable, useful, exploitable.  Maybe I should have used a Greek quote, since 'ecology' comes from the Greek word Oikos, meaning 'house'. The ecology of termites is the understanding of the ways they fit in the world, in habitats, in between other species, in time, in place, as ecosystem engineers, as food, even as annoyingly troublesome pests.
Termite ecology is a great topic to explore.  It's been a large part of my life.  They are not a great subject choice.  Termites are not fast-living animals.  They can have exceedingly long generation times. Termites are rarely seen.  If you can look one in the eye, it is probably involved in rare, short-term activity or it has been ripped from its nest and knows that it is about to die.  Check out termite behaviour.
If you are interested in social insect ecology, ants and bees are far more accessible and robust but if that doesn't put you off (yet), read on.
The main topics in termite ecology are habitat, niche, food, competition, symbiosis, predation, population, community, climate, patchiness, energetics, nests & mounds and life types, biogeography, ecosystem services, architecture and dispersal.
